After weeks of hard work we (Setmov and uncle Fab) proudly present you the first Una ROM for the galaxy Grand 2 I7102, based on 4.3 XXUANG4.
DISCLAIMER
As usual, your phone your responsability, we won't take any responsability if it flies out of the window or if your girlfriend/boyfriend runs away with it.
PLEASE, DO READ OP COMPLETELY AND CAREFULLY BEFORE ASKING ANY QUESTIONS, ANSWERS TO MOST PROBLEMS ARE THERE
WHAT IS UNA?
Una is a new concept that takes security to a new level.
Are you tired of seeing so much blatant, outrageous and shameless invasion of your privacy and data mining hidden behind nice sentences like "enhanced use experience" or "complete integration with the system"? We decided to develop secure ROMs where privacy means just that – Private!.
It’s free of charge, we are a non profit structure and we are not here to make big bucks
WHAT UNA ISN'T
UNA isn't a way to help you to stealthily buy massive destruction weapons to foment a coup d'etat in your favorite banana republic or to prepare the third world war.
UNA secures what leaves from your phone (ie your personnal data doesn't leak and no app can look over your shoulder to spy your activities), but it can't completely secure what comes into your phone.
Why is that?
Because it's just not possible to fully secure a phone from what comes into it, and anyone claiming to be able to do it is either a liar, or an ignorant, or both.
There are too many attacks, some not well documented, if documented at all, and some unknown to the public, and there are too many ways to hack a phone, especially if the user doesn't use his/her common sense.
If you are the type of person that installs apps from shaddy source and/or warez web sites (sites offering cracked paid apps) chances are that at some point you will unknowingly install a malware or a spyware. The same applies if you click on any link, specially on SMS' and emails, if you let any pop out window appear or if you don't protect your lockscreen with a password/pin/pattern and let anyone get physical access to your phone.
A bit of judgment and common sense can save you a lot of trouble, but there's unfortunately nothing UNA can do about it.
Then, if you use your phone to call through GSM your provider will know where you are. If he didn't you wouldn't be able to make any call, the signal has to find you and there's nothing UNA or anyone can do about it.
The only way to prevent that is to disable the phone functions (but then your phone will turn into a wifi only device) and reenable them when needed, head to the scripts section to learn how to do it.
Last but not least, bear in mind that the agencies have armies of tech savvy henchmen and 10 storeys computers, and tricks we can't even imagine, so think twice and use your brain before you attempt to outsmart them...
UNA IS FOR YOU IF:
. You are willing to learn how to use an unconventional ROM and generally speaking to understand how things work, even if it sometimes requires a little effort to fix this or that little problem (bear in mind that it took us a lot of work to develop Una to where it is now),
. You don't mind a few little occasional bugs here and there that come from all the restrictions the ROM contains,
. You want to take back ownership of your phone from google’s claws.
UNA IS NOT FOR YOU IF:
. All that you care about is the latest gimmick in the latest OS,
. You can't live without the google’s apps,
. You are the kind of person that never reads through the OP and only scroll down to the download section, and then complain that things don't work and/or ask stupid questions that have already been answered in OP.
An example? One guy makes a mod and writes clearly in OP that it's specifically for 4.2.2. Then some people complain: "it doesn't work on 4.4.2"...
ARE WE PARANOID TIN FOIL HATS? OR TERRORISTS? OR CARTEL BOSSES?
Nope, we only are people that don't see why we shouldn't be in control of our phones. Or why our phones can be wiped remotely, why apps or updates or who knows what can be downloaded and installed without asking for our consent, why SMS' can be sent without us to know, why we should pay for the bandwidth used for data mining and unwanted downloads, and why all those activities should deplete our battery and kill our RAM.
You think we are overreacting here?
You don't have to take our word for it, just download and install Network Log from here:
https://f-droid.org/repository/browse/?fdfilter=network+log&fdid=com.googlecode.networklog
Give it root permission, start logging and open some web pages. Come back to Network Log after a few minutes and see for yourself, you'll be surprised (or maybe horrified?) to find out that your android system, your settings, your kernel etc. connect to all sorts of funny IPs, including and foremost google’s.
Now you see what we mean?
It's time to go for Una
UNA'S FEATURES
. Rooted.
. Deodexed.
. Zipaligned.
. Busybox and sqlite installed.
. Init.d support and scripts.
. Auto start disabled for most apps.
. About 120 system apps, 40 framework jars, 30 permissions xmls and 25 libs removed, plus files here and there.
. Very low RAM and CPU consumption, more than 8 hours screen time with the WIFI on, 1% battery decrease every 10-12 hours while in stand by.
. Heavily and extensively modified system, in order to make it secure and prevent it from leaking your data.
. App Settings, Firewall and Xprivacy built-in, and already applied out of the box to make sure you are well protected.
. Xprivacy is a fantastic tool but it has one big limitation, it can't restrict the Android System from accessing your serial numbers and leaking it. For that reason these IDs have been edited as follows:
build.serial (androidboot.serialno), ro.boot.serialno and ro.serialno are both set to "1",
android id is set to "id",
net.hostname is set to "1".
. Wlan serial number set to "00000001" (this number identifies you everytime you connect to the internet, and Xprivacy can't do anything about it).
. USB ID (iSerial) set to 1.
. Unreadable cp access.
. Vulnerabilities patched thanks to Master Key Multi Fix.
. ADB disabled (can be re-enabled, see below).
. By default ADB, all google access (including youtube, blogspot and google search), the Live Wallpaper Picker and the Media Storage are disabled. You can re-enable some or all of them, instructions are in the "HOW TO USE THE ROM" section.
. Plenty of under the hood modifications to make the ROM fast and fluid.
. Multi-purpose navigation keys.
. Call button in contacts.
. Because secure doesn't mean ugly, the whole ROM has been themed with a beautiful green color (if there are enough requests other themes will follow), transparency, and Lollipop HD wallpapers.
. Multiwindows have been revamped, they are no longer only static in Samsung style but now they can float and be resized/minimized too, like on a computer.
. All apps can be opened in floating mode.
. KK style quad view multiwindows.
. Heaps of hand picked and carefully scrutinized open source apps.
There are 2 non open source apps (Greenify and Quick Pic) but they are safe, believe me, I have thoroughly examined them. Still, you can always uninstall them if you feel like it.
In time we will develop our own apps, but first we want to see how people respond to the Una concept...
Installed apps/tools
. 920 Editor, to create and edit scripts or text files.
. AF+ Firewall.
. Alarm clock.
. APG, to encrypt messages.
. App Settings, to restrict apps' permissions, change DPI on a per app basis and more.
. Arity, a calcultor.
. Conversations, a secure and encrypted chat, modded by uncle Fab for increased security.
. Fdroid, an alternative to the Play Store, and all the apps are open source!
. Floating stickies, to make small notes on the fly.
. FTP Server, to copy files to/from your phone wirelessly.
. Ghost Commander, a very powerful dual panel root file manager.
. Gravity Box, a theming engine.
. Greenify, to make apps behave by hibernating them when not in use.
. K9 Mail, an email client.
. Kernel Adiutor, if you feel like playing with kernel tweaks (but you have to know what you are doing).
. Lightning, a fast and light weight browser.
. Master Key Multi Fix, a patch to some vulnerabilities.
. Network Log, to check where your apps connect and chase unwanted connections.
. Open Camera.
. Tor (Orbot) for Android, modded by uncle Fab for increased security.
. OS Monitor, to monitor and kill your phone's processes, and more.
. Pale Moon, based on Firefox for Android, for a full desktop experience with Mozilla add-ons preinstalled for enhanced security.
. PDF Reader.
. Preferences Manager, to edit the otherwise difficult to read shared_prefs files in data/data.
. Quick Dic, a good selection of free dictionaries.
. Quick Pic, a Gallery app.
. Rmaps, a maps app where you can download maps from various sources for offline use.
. Search Light, a torch.
. Terminal Emulator, fire up your commands and show your phone who is the boss!
. Text Secure, a secure and encrypted SMS app, modded by uncle Fab for increased security.
. Tint Browser, another fast web browser.
. Urecord, to record sounds with different sample rates.
. USB Mass Storage Enabler, to connect your phone to any computer (note that it only mounts the external SD).
. Viper4Android FX, a powerful sound enhancer.
. Viper4Android XHiFi, some more sound enhancements.
. VLC, a video and music player favourite.
. WI-Fi Privacy Police, to secure your connections even better than they already are.
. Xposed Installer, a great framework that enables apps like App Settings or Xprivacy to work.
. Xprivacy, last but not least, the best privacy app.
WHY DO WE USE A 4.3 ROM AS BASE INSTEAD OF THE LATEST 4.4.2?
Because when it comes to privacy Kit Kat 4.4.x is a complete
disaster, the newer the android version the more buit-in spying there is (and the more difficult it is to remove it), despite google's sweet talk about "enhanced user's experience.
Lollipop seems to be even worse, but that's another story.
INSTALLATION
As usual, make a backup first!
Do backup your contacts and whatever is important because all your apps and data will be erased (your sd card contents won't be deleted though).
Do backup your /system/csc folder, in case you need it for later.
Do backup your efs folder (VERY IMPORTANT).
Open an android terminal from your phone and type:
su
enter, then type:
busybox dd if=/dev/block/mmcblk0p11 of=/sdcard/efs.img
enter, this will create an efs backup caled efs.img in your sd card.
To restore it, first make sure the efs.img is in your internal sd card, then type:
su
enter, then type:
busybox dd if=/sdcard/efs.img of=/dev/block/mmcblk0p11
enter, your efs will be restored in no time.
If that sounds like too much work you can use the scripts provided to backup/restore your efs, instructions are in the scripts section.
To install the ROM you need a Custom Recovery and Philz' comes highly recommended.
We chose Philz since AFAIK it's the only one that allows you to lock you recovery with a password (if your recovery is not password protected it wouldn't take more than 2 minutes for someone to disable your pattern or pin protected lockscreen and access all your personal data on the phone).
I'm not sure whether there's a Philz recovery or not for the Grand 2, if there isn't then CWM or TWRP will do.
Custom recovery installation instructions
You need to have Samsung drivers installed.
Boot your phone into download mode (press volume down and power at the same time).
Open Odin 3.07 and connect your phone.
Click on the PDA slot, navigate to where the Custom Recovery is located and select it.
DOUBLE CHECK AND MAKE SURE THAT "RE-PARTITION" IS UNTICKED (only "Auto Reboot" and "F.Reset Time" should be selected).
Click start and wait while Odin flashes the Recovery.
If everything went well your phone will now auto-reboot into the system. Go into recovery, you should see your brand new Custom Recovery.
If you are still on stock recovery then repeat the above steps, but this time untick “Auto Reboot” in Odin.
When in recovery, if before you reboot you see a text on the screen displaying “yes – disable flash recovery”, select it to avoid stock recovery overwriting the Custom Recovery.
Download Una for Grand 2 from here (click on the menu at the top right and go to the download section):
http://unaos.com
Unzip the ROM and copy it to the backup folder that is inside the clockworkmod folder in your sd card (if there's no backup folder create it by choosing "mkdir" in Ghost Commander).
Boot into recovery.
Go to restore from sdcard, choose 1970-01-01.10.06.02, and go for it!
IMPORTANT!!!
If you are on Kit Kat (4.4.2) you must downgrade first to stock 4.3 before you attempt to install Una ROM, otherwise you may end up with a bricked phone.
Here are 2 threads to assist you in the downgrading process:

http://forum.xda-developers.com/galaxy-grand-2/help/downgrade-to-4-3-t2857183
If it works please report here so that other people will know, thanks in advance!
Once it's done reboot, congratulations, you have installed Una ROM on your phone!
HOW TO USE THE ROM
. Swipe down to access the applications drawer.
. Swipe up to turn off the screen.
. Go to settings and set a stong password/pin/pattern protected lockscreen (recommended).
. Go in recovery and set a recovery password (recommended).
. Long pressing on the menu key toggles expanded desktop (full screen, no more navigation bar and no more status bar).
. Double pressing the menu key kills and hibernates the current application.
. Long pressing the recent key brings you back to the last application (convenient to switch from one app to another).
. Between the home and the back key there's a supplementary key that can display up to 12 apps (editable in gravity box).
Double pressing that key shows the sound panel, long pressing it shows the reboot menu (note that there's an option to take screenshots in the reboot menu).
. You can open an app in full screen mode by dragging it from the Flash Bar (the side bar), then you can drag and add more windows to the view (up to 4 on the same screen).
Or, you can open apps in resizable and movable floating mode by clicking on them (double tapping the top bar minimizes them into a bubble, double tapping the bubble restores them).
. Go to /system/etc/security/cacerts, check the certificates that are there (you'll find the certificate's name approximately by the middle of the file), and erase the ones you don't need/like.
When you want to transfer files to/from your phone open the USB Mass Storage Enabler app and enable mass storage, that's it. When you are done, don't forget to eject your phone from the computer and to reenable MTP from the app.
. When you install a new application, by default it will be fully restricted in both Xprivacy and the Firewall.
Before you open the newly installed app wait until the Xprivacy icon appears in the status bar, then and only then can you open it.
Most likely the app will crash.
Go to Xprivacy, open its settings and then usage data, you will see what restrictions caused the crash. Re enable some, provided that they are not too invasive.
Many apps require "load.Library" to be allowed in the shell section, that's ok.
Others may need to access the sd card, that's in the storage section and it's ok to allow it for apps that really need to access the storage, like players, cameras or file managers (for other apps try to keep it restricted).
Root apps obviously need "su" and/or 'sh", and sometimes "exec", in the shell section.
Always try to enable as few fields as possible, and bear in mind that data requested by an app is not necessarily needed for that app to work (especially true for identification, internet and mcc/mmc access).
Lastly, give the app internet access in the Firewall if, and only if, it needs it, and restrict some more permissions in App Settings.
If you can't tame the app consider uninstalling it and look for a similar one that has less built-in spyware.
SCRIPTS
. As said above, by default ADB, all google access (including youtube, blogspot and google search), the Live Wallpaper Picker and the Media Storage are disabled.
If you want to re-enable some or all of them, open the script folder located in system/etc.
Click on the desired script and choose edit.
Copy the whole text and paste it into the Android Terminal, voila, the script is automagically executed.
. You will see more scripts to disable/enable the Bluetooth, the FM Radio and the Phone.
If you disable the Phone and later want to re-enable it do as follows:
untick App Settings in Xposed's modules section, re-enable Phone, reboot, then enable App Settings again.
. Some scripts will enable you to backup/restore your efs partition and flash a recovery.img (to restore or flash an .img, make sure it's in your internal sd and execute the script).
. Other scripts can enable/disable am and pm, but don't play with it unless you know what you're doing.
. You can uninstall the Live Wallpaper Picker, the Wallpaper Chooser and the Media Storage if you want, or keep them disabled and resurrect them when needed.
. If you are very privacy concerned you should consider using the "uncle's phone lite" mod because it enables you to call with only the Phone and the Telephony Provider apps (CSC, Contacts, Contacts Storage, Logs Provider and STK are completely de-activated). That's the method I use to make calls, but you have to know that the dialler forces close after you complete the call (not a big deal in my opinion but still, I may look into it one of these days). You'll find the mod in the add-ons section.
ENCRYPTION
If encryption is your thing we have you covered with the following installed apps:
APG, Conversations, K9 Mail and Text Secure.
BUGS
. Quick Dic won't download any dictionary, actually it's not a bug but a Una restriction since Quick Dic downloads from a google owned web site.
If you need to download dictionaries, temporarly enable google by running the "enable_google" script (don't forget to disable it again when you're done). After you've run the script go to the firewall, open its settings, go to "Set custom script" and click "OK" (do the same if you decide to disable again google's stuff).
. For some reason the ADW Launcher doesn't allow transparency in the navigation bars while in portrait, I'm working on that.
. You can't download anything from Lightning and Tint Browser, that's because the Download Manager and the Download UI have been uninstalled. If you need to download something, copy the link and paste it in Pale Moon, it has its own download engine.
. I didn't have time to properly and restrictively set Text Secure (the SMS app), because I don't own this phone and the person I borrowed it from wanted it back ASAP. Sorry about that, you'll have to do it on your own (if you want to make it simple just restrict its internet access).
. All the installed apps work, but other apps you install may crash. I call that kind of apps "google’s henchmen", they only work if the play store services or the bla bla app are installed and of course they won't on Una since all that garbage has been removed.
If I install your app, why do you want to force me to install your boss' app too? Forget about those apps and search Fdroid, you'll find what you need...
. Depending the way you use your phone you may have to fine tune Xprivacy and reenable some permissions, I'm sorry for the inconvenience but it's impossible to set Xprivacy for all users since we all have different ways to use our phone.
ADD-ONS
. Sony Xperia Keyboard, flash it in recovery.
Credits KristianCarl for porting it, and unclefab for theming it in green.
It's not open source and that's why it's not included in the rom by default, but it's my every day keyboard because it works fine and because I themed it to make it look nice.
Don't give it internet access in the Firewall.
In Xprivacy, only allow "loadLibrary" in the shell section. You may have to enable a few fields in the contacts section depending your phone's configuration.
In App Settings, restrict "Read_Phone_State" and "Record_Audio".
I removed the Chinese Keyboard, tell me if you want it and I'll readd it.
. Universe Wallpapers
If there are enough users' requests then I'll upload the following:
. Uncle's phone lite (with clipboard and dialer) for hardcore users. It's safer than using the regular phone configuration, but the dialer forces close when you hang up the call. Flash it in recovery, wipe dalvik-cache, reboot.
. Completely disable internet access for the Android System. Lightning and Tint Browser won't connect anymore since they use the same web engine as the Android System, but Pale Moon still works thanks to its build-in web engine. Flash it in recovery, wipe dalvik-cache, reboot.
RECOMMENDED NON OPEN SOURCE APPS
. Pri-fy, from chainfire the root master:

. Logging Test:

UPDATES?
I'm working on some improvements on kernel and system level to make Una even more secure, but I will release them for the Grand 2 if, and only if, there are enough users' feedback for the current version, because it's a lot of work to implement such stuff in a ROM.
No ETA though, you'll have to be patient because now we have to design and release Una for many other phones.
Still, any suggestions/comments/bug reports are welcome, help us to improve Una!
FEATURE REQUESTS
Yeah, sure, we'll see what we can do but we don't promise anything
SCREENSHOTS
I didn't have time to make screenshots since I ran short of time, so the ones you'll see here come from another phone.
They are very similar in shape, layout and color though, and you'll get the idea.
That's all for now, enjoy the ROM!!!

i dont own a galaxy grand 2 , although i may have to get one , but thank you for sharing your work. i'm not a developer so i can only imagine ( which probably falls way short ) of what this took to build.:thumbsup:
"all i can really do , is stay out of my own way and let the will of heaven be done"
Please do a 4.4.4/4.4.2 version. What about the security? Like anyone can hack into your phone....

Thank you soooooo much to take time to reply and show how much consideration and respect you have for someone that worked about 100 hours to build a rom and share it for free with the community.
It feels sad to know that you won t run Una rom on your phone, and thanks again for informing us that we won t count such a great person like you amongst our users, but maybe next time you should read OP:
UNA IS NOT FOR YOU IF:
. All that you care about is the latest gimmick in the latest OS,
. You can't live without the google’s apps,
. You are the kind of person that never reads through the OP and only scroll down to the download section, and then complain that things don't work and/or ask stupid questions that have already been answered in OP.

Well, time will tell, but so far if you were me what would you think/do?
Thanks for your valient efforts.
But most of the phones would have been upgraded
to k.k. and downgrading them to 4.3 is rather risky.
Even I wonder whether I can downgrade to 4.3 add you rightly mentioned
about 4.4 and 5 android versions.
Even then I will try to down grade to 4.3 and also
try this room. I am willing to take the risk for the developer.

I really dislike 4.4 because it s full of spying, but on the other hand I definitely could build a 4.4 rom for the Grand 2 cuz I can understand that not many people want to take the risk to downgrade.
The only problem is that I don t own the phone, and that the person I borrowed it from doesn t want me to install 4.4 on it, because of knox and because 4.3 runs well.
One thing you have to bear in mind is that latest android version doesn t mean best version, and since 4.1 it s actually been quite the opposite.
Google install 2-3 gimmicks to "enhance users' experience" bla bla, and at the same time strengthens its grip on android.
It got particularly bad with 4.4, and I read reports that it went even worse with 5x...

spying? Meh. 80% of people are on kitkat and a few are on lollipop. No reports of something hack-ish.

Most people don t realise they are being spyied.
Do one test.
Download network log from here:
https://f-droid.org/repository/browse/?fdfilter=network+log&fdid=com.googlecode.networklog
Install it, open it, give it root access and start logging by clicking "logging on" on the top.
Then do some browsing, going to this or that site, but don t go to any google related web site (no search, no youtube etc.).
Come back to network log, you will see that your phone connected to many funny addresses, including of course google, and that quite a lot of data has been transfered both inbound and outbound.
That s just a small test, there s actually much more than that but you ll get the idea.
You could make another test with xprivacy, and if you do so you ll see that all apps request various private data like ids and cell towers location.
The thing is that the higher the android version the more difficult it is to prevent that data mining, data mining that is little more than spying by looking over your shoulder.
Una roms have been designed to prevent that, and more (see OP), but it s up to everybody to install it or not.
I really appreciate your Hard work , I can imagine how much hard work you would have done by working on a phone which you do not own , borrowing it again and again , testing the ROM on someone else's phone and the fear of bricking it . But as someone mentioned in the thread many users are on 4.4 . Many here fear bricking there devices while downgrading it. The mere fact that you have to downgrade your device to use the ROM is what cause of lack of users . personally I really liked what your ROM offers. Just to help you for further development H6 is the most stable and without Knox count firmware. Some 60-70 % users who flash custom ROM are on this firmware and even many custom Roms use it as a base . Hope to see this ROM on kk .
Best of luck.

I really dislike 4.4 because it s full of spying, but on the other hand I definitely could build a 4.4 rom for the Grand 2 cuz I can understand that not many people want to take the risk to downgrade.
The only problem is that I don t own the phone, and that the person I borrowed it from doesn t want me to install 4.4 on it, because of knox and because 4.3 runs well.
One thing you have to bear in mind is that latest android version doesn t mean best version, and since 4.1 it s actually been quite the opposite.
Google install 2-3 gimmicks to "enhance users' experience" bla bla, and at the same time strengthens its grip on android.
It got particularly bad with 4.4, and I read reports that it went even worse with 5x...

Definitely I wanna going to try this rom. I never said 4.4. Or 5 is best versions of android.
But the fact is downgrading is some what risky. Eben then I am going to try.
No need to pay me for taking sweet.

I didn t read everything about the downgrade procedure, but of what I have read you have to odin flash a specific KK version first, and then a specific 4.3.
Anyway, if it s really that risky maybe you shouldn t try and wait until we manage to release a 4.4 Una rom.
The problem is that the person that owns that phone uses it for business purposes, so I have to be very careful not to loose all the whatsapp, bbm etc. contacts and settings, and if it was ok to backup her rom, work on making una during nights and then restoring her original rom in the early morning, it would be a different story to switch from 4.3 to 4.4 to again 4.3 every night...
Let s see if I can convince her to use 4.4 as her daily rom, but I can t lie and tell her that 4.4 is better than 4.3, and I don t think she will accept to sacrifice her phone.
I meet her again next month and I ll keep you informed in case she accepts.
For now what you can do if you want to make your phone more private and secure is to follow what I explain in my security thread (check my signature "how to secure your phone").

All builds prior to NK1 are without KNOX.
NH6 is good and speedy.
I'm a dev too, and I don't recommend the over-VIP experience you're using to grab customers. I ain't sure, but it looks humiliating to you to give picky users a VIP experience.
Just tell them to get the hell off the thread if they hate the idea (I really like it and would've upgraded if I was a TW user. I use AOSP CM).
Also, the screenshots are from a Grand 1, and our device is SM-G7102, not I7102. You mixed up with the Grand 1 i9082.
Oah you know, customers is maybe not the right word, unless they pay which is not the case!
Then I don t know if that can be called a vip experience, but I understand your point, maybe sometimes I m too nice, what to do...
For the screenshots, I didn t mix 'em, I explained in OP that I didn't have time to make any since I ran short of time, and that the ones I put here come from another phone.
A galaxy grand i9082, yep, well done, you have a sharp eye!
They are very similar in shape, layout and color (apart from the cascade icon to minimize windows that Samsung has removed after 4.2.2, a big mistake to my opinion), so people can get the idea.

In some ways you are right, but we think that being professional is not a bad thing, despite the fact that the forum is full of picky users, ready to make bad comments even without trying the product. Of course, we can and we will also give a VIP experience, but it is reserved for the ones that will earn it.
In any case we appreciate your support. Thank you

Hello, everyone!
If you aren't an expert - that's okay. Everyone is welcome and you're free to ask questions.
Make sure to check the date this post was updated (I may forget to update the date in the title) which is located at the bottom of this post. If this post hasn't been updated in more than a month, contact me and I'll refresh everything.
Quick Introduction:
I'm new to the Yoga Book squad, and I've noticed one major downside.... the forums are a total mess. So what I'm hoping to do, is to keep this thread as up-to-date as possible, with links to guides, development progress and anything else.
I figure to make this more... tidy, I will enforce a colour-coding system for each sub-thread-guide-thingy, so you can instantly tell whether a guide or method to do something to your Yoga Book is risky, and most likely experimental, or is well tested. These will probably be done via experiments on my own Book (the wifi-only version), but of course I will hope via this community thread I will be able to provide more detailed statistics and such as everyone does their own thing to their device.
If you have anything to add to this thread, or would like to help out with anything; please feel free to contact me or just tell me what you're thinking - I'll do my best to read everyone's replies.
General Yoga Book Information
To my knowledge, there are two versions of the Yoga Book, each with two sub-versions for the OS:
1.) YB1-X9aF - this is the Wi-Fi version
2.) YB1-X9aL - this is the LTE/4G version
Where the "a" between the 9 and the F/L is either a zero or a one, depending on the installed OS (Android: 0, Windows 10: 1)
The SIM card is a Nano-SIM with 3G capability.
Other than that, all Yoga Book devices share the following specifications:
- 10.1 inch IPS display, of resolution 1920x1200
- Intel Atom x5-Z8550 processor, which:
----+ Has an architecture of x86_64
----+ Core base clock of 1.44 gigahertz
----+ Core boost clock of 2.4 gigahertz
----+ 4 cores and 4 threads
- Battery capacity of 8500 milliampere hours
- On-board storage of 64 gigabytes of solid-state storage (SSD)
- 4 gigabytes of random-access memory (RAM)
- A microSD card slot capable of up to 128 gigabytes of storage
- Two camera's, one above the display and one on the keyboard
- Wi-Fi (802.11 ac) and Bluetooth (v4)
- 3.5 millimetre headphone jack
- Micro-USB 2.0 OTG port
- Micro-HDMI port
Colour (or color) Codes and Tags:
For those who like using grey-scale display filters or whom are colour blind, I've added a "level" to each of them, where level 3 is like... crazy meltdown experimentation mode, and 1 is stable-ish (probably as stable as it'll get unless a REAL developer takes on the challenge).
[X] - Means that you will have to delete some or all of your data for it to work
[R] - Means that it requires a Rooted device
[Level 3] VERY EXPERIMENTAL - Use with caution, and with the knowledge that you may boot-loop, brick your device or lose your data!!! OR ALL OF THOSE THINGS!! Make sure to backup everything you hold dear, and just for good measure you'll have something to fallback on.
[Level 2] NOT WELL-TESTED - This will probably work for most people, but things may be unstable at the best of times. Again, make sure you have a backup before trying level 2 items.
[Level 1] 99% FINE - If there's an issue, it's probably your own fault... but again, I can't guarantee that everything I or anyone else does is perfect and will work for everyone! You should probably still have a backup, but if you're lazy like myself it's okay, I forgive you.

[1][X] Unlocking the Bootloader
earthCallingAngela wrote a really nice guide for unlocking the bootloader. The original thread is here, but for those who are too lazy to open the link in a new tab I've quoted the information.
IF YOU APPRECIATE THEIR EFFORTS GO AND THANK THEIR ORIGINAL POST!!!
Remember, unlocking your devices bootloader will format your storage (meaning you'll lose all of your data), so backup anything important before proceeding.
earthCallingAngela's OP: https://forum.xda-developers.com/yoga-book/how-to/how-to-unlock-bootloader-t3502216
I hope this is useful information. It took me a bit to figure it out due to a lot of conflicting information, since the procedure has changed, perhaps several times, since the first version of Android. Also, I'll probably forget myself.
Please note that I've performed these steps on Linux (Specifically Arch Linux). Others have pointed out that if you have issues executing step 7 from Windows, you may need to follow this post.
1. Install Android Studio, or otherwise obtain the latest versions of the adb and fastboot programs. I think Windows users also need to install a USB driver, but I run Linux, so I am not sure about that procedure.
2. Gain access to the developer options on the tablet. Go to the settings, and find the "about tablet" section. Scroll down to the "Software version" section and tap on that several times until it says that you are now a developer. Feel special.
3. Go to the new "Developer options" setting. Select "OEM unlocking." Also, I selected "USB debugging" as a straightforward way to reboot into the boot loader.
4. Connect to the computer on which you've installed adb and fastboot.
5. Type 'adb devices' to see your device listed. The tablet will ask you if you're sure you want to allow the computer access to it. Answer in the affirmative, and save that option.
6. Type 'adb reboot-bootloader' to do just that.
7. After you see the innards of your 'droid, type 'fastboot flashing unlock' . On Linux, you may need root permissions to do this. The tablet will ask you to confirm (select with up/down volume, and accept with the power button), and will then erase all of your data! I didn't worry about this as I'm all on Google services, and so they can be restored easily enough.

[3] TWRP Custom Recovery
danjac has written a post about his attempt at getting a modified version of TWRP running on his Yoga Book. From what I can tell it was a success, besides a few bugs (which are avoidable... I think).
WARNING! MAKE SURE YOU READ THESE!!
Before you go ahead and just flash his version, make sure you know the consequences that could arise if something goes wrong. If the recovery of your device screws up, you don't really have much to bring it back to life with. Even though there shouldn't be many things to worry about, it's still very risky.
In fact, it is recommended you ONLY temporarily boot into TWRP, instead of just flashing it like you would on another device. danjac's OP gives more information for you to use.
If you think you are willing to take the risk and know what you're doing, I highly suggest you make a complete backup of your device if possible. So far there isn't really a way to get your stock recovery back (since we don't have a custom ROM or a way to download Lenovo's modified version online).
danjac's OP: https://forum.xda-developers.com/yoga-book/development/recovery-twrp-t3533980
[2] Rooting (via Magisk)
danjac wrote the first guide to rooting the Yoga Book, and you should, again, go and thank his original post. However, his OP is now a bit outdated, Magisk (currently v12.0) now includes a root module (MagiskSU) based on phh's SuperUser.
Please note: If you are already rooted via a different method (and maybe you want to change because it didn't work... or something like that) you have to go into your super-user manager and uninstall it. If you have a previous version of Magisk installed, there is an uninstall ZIP that you can flash, which will remove any Magisk version, including MagiskSU. Again, more details on the main Magisk thread.
Do I NEED to unlock my bootloader to Root my device?
The short answer is yes, and the long answer is sort-of. You only need to unlock your bootloader if your ROM doesn't support Rooting out-of-the-box (which in Lenovo's case, it isn't supported). However, you can lock your bootloader afterwards if it's such a concern to you. Yeah, you probably will stop receiving over-the-air updates from Lenovo, but they're probably not going to push out another update for a long while, so in my opinion it's nothing to worry about.
Follow the instructions on the main Magisk page to install it if you're new to Magisk, but if you know a thing or two then I'll paraphrase:
- Flash the latest Magisk ZIP file via the TWRP Recovery (if you have it) or just flash it over ADB
- You should also download the Magisk Manager from the Play Store to make sure you're always up-to-date

[2] Dual-booting Android and Windows 10
Since there isn't a place to get the Android side of things, I won't put too much info here.
Although if you're already running the Android version and want to know how to put Windows 10 on your device too, look at this thread.
Dual-booting OT: https://forum.xda-developers.com/yoga-book/help/android-to-windows-hack-dual-boot-option-t3475733
[3][X] Custom ROM
Currently there is no custom ROM which supports the Yoga Book, mainly for the simple fact not many people own the device. However, if we make enough noise in the community I'm sure someone will crack under the pressure ;P
Although, I'm doing my best efforts to merge the device drivers and such into the Android Source code, but you shouldn't get your hopes up. If I ever get it working, it will probably be unstable and not that great (I don't have much experience with the details of the Android OS), I'm running off my knowledge of the Linux OS.
If you're using the Windows 10 version of the Yoga Book (I'm sorry you paid the extra $50!!), hopefully Lenovo will at least release a version of their own ROM soon (or put it back from what I've heard). I've also heard that they're upgrading to Nougat in October (of 2017)... so we've got plenty of time to find another solution to our sorrows.
Information for Developers:
Someone has also posted a backup of their working Lenovo-customised Android OS, but I won't post a link here because:
- It's only a backup
- May draw un-wanted attention to the link
But if you're a developer and you think that will help you, you can easily find it somewhere in these forums.
EDIT: The link has now been removed (I can't find it)
If you're trying to
Code:
repo sync
the AOSP and you're getting stuck syncing the work tree, try doing this (from the folder you're trying to sync to):
Code:
rm -rf frameworks/compile/slang/
mkdir /home/<user>/slang_helper
sudo ln -s /home/<user>/slang_helper frameworks/compile/slang
Please be careful when typing commands into your terminal, especially from the internet, and especially when you don't understand what the commands are doing.

[2] Linux without removing Android
Thanks to @Tiggi2017 for making the first guide. His OT here is a good one to read through if you're interested in this.
Via a few apps and some commands, you're able to have a "Linux" OS running on your Android device with the Halo Keyboard and such still working perfectly.
His original method doesn't need Root access apparently. However, there are other methods that may be easier for some people if they have a Rooted device. Look through the comments in that thread for more information.

[2] Changing the DPI
WARNING! Do not change your DPI to extreme values! You may render your device useless (unless you already have set up ADB and know how to revert the changes)!
Thanks to melando for bringing up the actual default DPI values.
Just so you are aware, if you're running Android 7 (Nougat) or later, you can adjust the "DPI" to some preset values from the settings app.
Using this site, I calculated that the Yoga Book has a technical DPI of 224 pixels per inch, with a resolution of 1920 by 1200 pixels, over a 10.1" screen (diagonal). However, the default Lenovo has set it to may be actually 280. They suggest that you may find it better if the DPI is set to 240.
This is a trivial modification if your device is Rooted. All you have to do is open the Play Store, and search for something along the lines of "DPI changer", and find an app that has good reviews.
An example app would be "Easy DPI Changer [Root]"
If your device does not have Root, then you will have to have a computer with ADB installed.
To install ADB, do a quick Google. There's bound to be a guide there somewhere (I'll put one here soon).
Once you have ADB installed, you can follow this easy guide to change your DPI to whatever you like.
DPI Calculator: http://dpi.lv/
Non-Root Method: http://www.androidbeat.com/2015/07/how-to-change-dpi-of-android-device-without-root/
[1] Recommended Apps...?
There isn't anything here as of yet, because I haven't gotten far enough to look for any good apps that work well with the Yoga Book. So right now I'm going to rely on everyone else for that. I'll get there eventually.
However, you should at least download Magisk Manager from the Play Store, to manage your Root and other neato Magisk features.
If you're a developer, and need guinea pigs to test your stuff on, I am happy to help anyway I can (and I'm sure much of the community is too).
If anyone needs help, I'll do my best to assist, but if it's anything too tedious (such as teaching you how TWRP works or something along those lines), you should probably have a look on the internet for tutorials and guides for that stuff. There are plenty of people out there who can explain concepts better than myself.

Simple customisations!
[1] Touch-pad Customiser
This program was first put into the spotlight by dinosauria123, so go to their original post and thank them for finding this.
This small program lets you modify some simple variables associated with your touch pad, only requiring a reboot after you change something.
Features:
- Setting extended right click area
- Setting unlock area
- Setting mouse pointer acceleration
- Setting scroll direction
- Disable Touchpad clicking (added in version 1.4)

[1] Minor Halo KB Customisations
If you were wondering if there was a simple and easy way to lower the brightness of the Halo Keyboard, or just get rid of those pesky battery-draining touch vibrations for every key press, there is a way!!
Best of all, you don't have to download it! It's already installed!!
To find this not-so-well-hidden app, you have to either go to your Program Files, or open the good-old Control Panel (thanks to urayandro for pointing out that it's in the Control Panel!).
Control Panel method: Once you're in the Control Panel, just click on "Appearance and Personalisation", and you will find the "Halo Keyboard" program right at the bottom.
Program Files method: For 99.9% of people this is on your Local Drive (C: ). It may be located in your normal Program Files or it may be in your x86 Program Files, I'm assuming it depends on whether you're using the Windows 10 your device originally came with, or you have re-installed it (thanks to sawyerbenjamin for informing me that for them, it was in the normal Program Files folder). Assuming it's in your normal program files; go to Program Files/Lenovo/ and there it is. The application name is "ControlApp.exe". You can also make a shortcut to this application - I put a shortcut on my Desktop.
It allows you to:
- Toggle the touch tone/sound
- Toggle the vibration on keypress
- Adjust the time it takes for the keyboard lights to turn off
- Adjust the backlight (or whatever that is called) brightness for the whole keyboard
Risky or experimental customisations!
[2] Using AMIDuOS (Android Emu)
Update: I've spent a bit of time trying to use this, and in my opinion it's not worth the time. But if you need a development environment for something, it's pretty good at that. :/
In my attempt at replacing my Windows 10 installation with any version of Android I could find, I ran across this program called AMIDuOS. It's similar to emulating an Android system while you're in Windows, but instead of running it in a virtual environment, it runs directly on your x86 hardware (which is what the Yoga Book uses).
If you're cool with having a Windows 10 version of the Yoga Book, but still want to use some Android applications (possibly for drawing, or maybe just because the Android ecosystem is miles better compared to the Windows one) this may be a good solution for you.
Currently, they support Lollipop and Jellybean (not Marshmallow). However, this program is not free. You can trial it for free though. I'm fairly certain the full price is $10 USD.
It's not a difficult thing to set up (apparently), so if you wanna try something out and know how to deal with possible emulation problems (although unlikely) it may be worth it.
AMIDuOS Website: http://www.amiduos.com/
[2] Process Lasso
Huh? Process what-now? Yep, Process Lasso is a very complex program filled to the brim with algorithms tailored mainly towards getting the best performance and responsiveness, and to control those pesky rogue background processes that slow down your device when you don't need them to.
This program is completely free (but it does have a Pro version if you want a few extra customisation's and want to support the developers) and I've found it works pretty well, especially with a low-power device like the Yoga Book.
Since the Yoga Book is meant to be a very portable device, I'm not using Process Lasso to get maximum performance (as that would obviously drain the battery life quickly), I'm using it to make sure that if there's a program that needs to use power and deplete my battery life, then it's something I want - not some dodgy Windows background processes or other stuff like that.
It's pretty easy to set up. I've got a few of the main features enabled, and I recommend that you use similar settings.
I've enabled:
- ProBalance; this will keep the background processes in check, and allow the foreground processes to take the reigns of your CPU, insuring you experience minimal stutters.
- SmartTrim; this is an optional one, since I'm constantly micro-managing the applications I've got installed on my 64GB internal drive, this should help to prolong the performance of my drive, making sure it's well pruned (that's a pretty good analogy actually)
I've turned off the tray-icon showing me the CPU utilisation, so that doesn't need to waste any of my precious battery life (I'm usually a battery-life extremest), but you don't need to do that.
So if you're experiencing major delays when just doing simple things like moving around the Windows 10 user interface due to rogue background processes, I highly recommend you give this program a try.
Also, if you're a pro-ish-user like myself, feel free to dive deeper into the program. It's filled with toggles and adjustable's for you to play with and tailor the program to your needs, and almost everything you can change is accompanied with a tool-tip explaining what it does. Enjoy! But of course, as always, be careful of what you change - there are some things that could make your system really slow and or unstable.
P.S. The Yoga Book uses the 64-bit system, so choose that version of the program.

I'm not entirely sure, however flashing something to your device (via TWRP at least) does require an unlocked bootloader. So without an unlocked bootloader, I don't think there's a way to install MagiskSU. Sorry about that... :/
I will have a look around and see what I can find, though.

So I've done more looking around and here is your answer: Yyyyeeeeaaaahhhhhh......?
Magisk itself does not require an unlocked bootloader, however, it does require root access. Usually to get root access you need to unlock your bootloader, unless it comes already rooted in a custom ROM (but in our case, it doesn't). Unlocking the bootloader is a relatively safe procedure to perform, so [in my opinion] you shouldn't have anything to worry about!

I found it in my normal Program Files folder. (x86) only contained a folder for LenovoPaper.

Huh, well it must depend on whether you kept the original installation of Windows that came on the device, or whether you reinstalled it (or came from Android). I'll add that information. Thanks!

Same here. In my device is also only contain LenovoPaper under \Program Files (x86)\LenovoPaper
What i mean with retro control panel is old window's control panel. not the win10 setting. You can access it by:
1. Click start and type "control panel" then press enter.
2. You should see control panel window that similar to older version of windows.
3. Go to "Appearance and Personalization
4. Under there you should see "HaloKeyboard" shortcut.
You can also create another shortcut of this app by right-clicking it then choose create shortcut. Windows will make another shortcut on the desktop. I did this to get easier access when need to adjust keyboard brightness.
Hey there,
i think there is a way to flash the win 10 image on my yb1-x90f. just don't wont to brick it and so i have a few questions to all of you experts. in other words, i need your help
there is a quide i found in internet, which i think could work. But there are words i've never read before like "RUSB". is this an important word? i attached as low quality pdf...
there is also the win 10 image online. but we have to pay for it because it's "exclusive" stuff. 50$
maybe we can put together, 50/50 so its 25$ for me and you?
i think you know which page is meant. if not pm me
like descriped in the guide, (part 3) we have to select "Boot Menu" and after that "EFI USB Device"
But my bootloader looks different (android version).
is there a way to flash the image via original android bootloader/recovery or do we need to find a way to get into the other bootloader?
in this post: https://forum.xda-developers.com/yoga-book/help/bricked-yoga-book-yb1-x90l-t3537048
@mmusaad managed to get into this kind of "mode" but i think its a dangerous way and he had a big luck to "unbrick" his device. maybe onyone find an easy way to go into this "windows bootloader" or whatever?
so maybe we can work togehter

Probably wrong translation from Chinese... Should read USB-R. There are USB Ports which don't support remote drives

Windows was never free, that's why the Windows Yoga Book is $50 more expensive. A Win-Image will not help you either, as Lenovo brands the Product Key into the Bios.

OMG sometimes i think "together" :highfive: is a heavy word... :crying:
what about this ? (see attachement)
and stop letting me look like an idiot...
I'm on the YB1-X91F, which is the Windows version. Unfortunately for us, the Android and Windows versions of the Yoga Book have totally different BIOS's. This is the main thing stopping us from being able to dual-boot.
Easy-firmware has both the Android and Windows' ROM's, but they only provide instructions on how to overwrite the current operating system, not the opposite ones. I have downloaded everything they have on the Android side of things, and everything except the Windows ROM on the Windows side.
While I was messing around with my device, I did brick it. But I was able to get an SD-card with a Windows bootable "USB" install on it, and went through the installation process on my external keyboard. Then from there was able to install the drivers and restore the Windows version with everything working after a bit of time. I don't know how different this would be if you don't mind getting rid of the Android bootloader totally, but that's not really recommended.
What we'd need for getting Android alongside the Windows version is a way to get a working Fastboot/ADB connection.
For the Android version getting Windows alongside it, you need a way to get the Android bootloader to point to and recognise the Windows installation. However, this is almost impossible unless you have a custom ROM, which we do not have that supports the Yoga Book. You could probably delete Android totally, and then install Windows from there, but I'm not 100% sure because I haven't messed around with the Android version of the tablet.
We'd need a way to get the Android BIOS and Fastboot off of it so we can then use it to our advantage.

That probably flashes a valid Serial Number into the Bios...
DPI settings
I believe default DPI may actually be 280 - there's a Lenovo forum thread recommending setting it to 240 which I have found reduces the size of icons etc. so 224 does not seem right

Thanks for the information! I've added a bit to the DPI section about the other values.
