Hello to you all people of XDA, firstly I must state that I've scoured the forums far and wide and have yet to find some valuable info regarding my problem.
So what we're doing is developing (or trying to, as is obvious from this post) a custom rom for the Galaxy S2 which would be used for a single medical application for sensor tracking and the processing and displaying of said data on the SGS2, while at the same time sending it to his/her doctor.
What we need to be able to achieve with this rom is to put it into the hands of the end-user (a chronical patient which will in turn be able to stay at home instead of being hospitalized) and be able to completely lock down the phone for his use (I know, it sounds terrible) so that he loses the phone/sms/games/youtube/internet functionality as we need the phone to run as stable and for as long as possible without any additional battery stress (the constant sending, processing and processing of data seems enough of a problem for now).
I've searched into some custom roms but we eventually came up with the need for a stock Samsung rom which could be modified as we want to.
See this is where the problem begins, we can't seem to get the phone rooted, the ROM customized and then unrooted again so that the phone can't be fiddled with anymore, except when it's completely dead and we need to fix it.
So to cap it all up:
It needs to allow for a custom load and bootscreen (I almost got this to work)
It needs to be completely locked down for the end user.
It has to have full BT, NFC and WiFi functionality
It has to be able to call out and reciev calls, but only to/from specific numbers (911, doctor, etc..)
It has to basically allow for 2-3 programs to be running, while the others simply don't exist on the phone.
I am terribly sorry if anything like this has been asked about before, I swear I put 2 days of me life into researching already.
Any help, any help at all, ideas and solutions, but mostly links are welcome.
Thank you and good day to all.
Just a detail, but the SGS2 doesn't have the NFC functionality. Project seems to be possible, I would look into CyanogenMod sources if I was you.

Why are you afraid of leaving the phone rooted and in hands of the patient?
Is he so uncritical that he can search the web and find means of unrooting a mobile phone and then get around to actually doing it?

Block all internet access apart from ones you want or you can just setup iptables rules, shouldnt need root apart from when setting it up
As far as removing programs, just delete the apks from the zip, or before you remove root. My sig has a list of all apks in a upto date rom and what they do.
You can use gemini app manager to control autoruns (stop them etc) also to block (hide and disable apps)
As far removing root, your best bet is to once you are done, use adb (from the android sdk) to remove the superuser.apk then flash the stock kernel back, as far as I know without superuser apps cant grain root permisions.
OR
This app will allow you to block any app behind a password
This app will block incoming and outgoing sms and calls on white and blacklists
Custom boot logo (the first screen before the animation)
Custom boot animation need to go into system/media, I am not sure about the format but there are loads around, like this thread has loads, stock kernel should support them.
I hope that helps
Most of that is easily possible.
If you listed the apps needing removed, the apk files just need deleted.
To control calls, you can use a third party app from market for that.
It's possible to have the custom rom unrooted, and easily flashed, regardless of how badly the phone gets rooted
Boot animation is easy anyway... If you can provide it in a zip like other ones (zip containing numbered png's) then it's a piece of cake.
A little bit of clever firewall stuff would prevent any web traffic, in or out, except to your defined server, which is obviously a concern when a phone is handling sensitive medical info.

The phones are going to be used by around 500.000 people in a year, it's not that we want to take anything away from the user, it's more about not having any problems with the firmware - like ever.
Thanks for all the help!

LucLucLuc, not sure where you live, but you're entering the patient confidentiality minefield with big, big boots.
Apart from the legal considerations, your question is definitely OS related and not device related.
I see what you want, but legally - where I live anyway - it's too much of a grey area to get involved with.
I use call recording a lot for referrals and info from other doctors, but I've always asked the other party if they're OK with it. I won't record patient conversations, and I won't accept any files whatsoever that have seen RIS or PACS first - not worth it.
Can't see it's worth your while, but I'd appreciate it if you keep me informed should you decide to work on it.
Big boots indeed
We are from Slovenia, Europe.
I'm actually just a student doing the research and some basic Android programming, thank god I wasn't let into the bigger of the projects
But yes, this project is a colaboration of several european firms and you can read more about it at chiron-project.eu - it's a very very interesting project afaic.
I don't think we'll be swimming with lawyer piranhas soon though, the project uses sensor data (which sorta is a privacy issue) which will be monitored on a tablet running Android (currently testing the Galaxy tab 10.1 - we were lucky to order one before Steve had another one of his fits), proccessed in real time and then stored on the central server, from where it will only be accessible by the patients doctor.
Patient consents are dealt with before we even start talking about mobile hospitalizations.
It's very encouraging to see some actual interest, if anyone wants to know more about anything related to this project contact me at [email protected]
Thanks again for all the help.
I hope this proves useful to someone, but especially noobs like myself! I've searched high and low for a a way to access and install apps that are either restricted by country (I'm in Vancouver, BC) or by device type of and up to now was only able to find references here at XDA that involve using VPN. If the following tip is already common knowledge and I somehow overlooked it, I apologize in advance.
Yesterday I ran across this article handy applet that so far has worked flawlessly for me:
Clearly I can't post URLs yet but the applet "Real APK Leacher" can be downloaded at:
www[dot]mediafire[dot]com[slash]?5vibfddvxmh98y
No need to install anything, but just unzip the DL into any new folder and run it directly from there. It does require Java Runtime Environment 1.5.0 or later. First time the tool is launched it prompts you for a DeviceID and associated account and P/W for the device. I used the DeviceID for my Galaxy S2.
(To find the DeviceID on a phone, enter [*#*#8255#*#*] (not including the brackets), and find the lines that begin with "JID="and "DeviceID-".
When I first ran the tool, I ran a search and got no results.. Found that the trick is to enter the search term(s) and then select the "custom" radio button. I've used the tool to successfully DL and install 1) Google Currents, 2) Onlive Desktop, 3) USAA Mobile Banking, 4) HBO GO, 5) Canada Post App, 6) UPS app, 7) Fedex 8) Hulu+ 9) all Amazon apps, 10) Realtor.ca, and many others. Till now I haven't run across any app I wanted that I haven't been able to install using the tool. Hope you have as much luck as I have with it.
After downloading the APKs to your computer desktop, simply transfer to the Prime via you're method of choice and install.

I tried to be as detailed as possible in my post (it was late, I was tired, perhaps I wasn't) which is why I went to the trouble of pointing out how I used my smartphone (the GS2) to carry out the procedure myself. I certainly don't claim to know exactly how the tool works behind the scenes, but I think it most likely needs to "fool" the source it accesses to DL the requested APKs into thinking the DL request is coming from a phone rather than a tablet.
In any case, there are probably many ways in which to retrieve a DeviceID. The method I went to the trouble of describing just happens to be the only way that I know how to do so. If you know of another... GREAT... use it. If not, then well, I think anyone frequenting these forums is probably clever enough to figure out/search for other ways.
In this day and age, I don't think that there are many tablet owners out there that don't also own or have access to a phone as well. In light of this fact, I assumed (perhaps unwisely) that readers of this thread don't require the same level of handholding/specificity that less tech-savvy members of the population might.
For those who've found other work-arounds to achieve the same end and are happy with their method, well, this post isn't meant for you. For others, like me, who've been seeking a simpler way, I truly hope you find the tool as useful as I have.

Just googled the tool and seems it's getting quite a bit of attention; certainly not unknown. Favourable reviews/mentions from well known and respected sites. I In fact, I seems like someone here at XDA beat me to the punch in extolling its virtues ... found link to an active thread in the General Section.
While there are ways to check out executables of questionable provenance (particularly a Java applet on a PC) without endangering/in a secure environment, particularly when link to said executable comes from a noob poster such as myself, you are wise indeed to be cautious! For the adventurous among you, check it out at your own risk.
Searching on "real apk leecher" (note the correct spelling), it looks like this tool came out a week ago. It wants your email acct, password, and device ID. At least to start out.
From the screenshot, the apparent dev, Nhat Cuong Mobile, is a Vietnamese outfit with website here: http://nhatcuong.vn/. However, it's a mobile phone sales & repair site, and I can't find any info on software development (I can speak Viet).
If you do try this out, be extremely wary.
If you're rooted try Market Enabler (in the market), change to code to whatever network in whatever country, force close the market app (drag it to App info, and force close from there), then open it again, and voila Access to all the apps you couldn't access before.

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.

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.

[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.

Does anybody know, whether bootloader unlocking is necessary for magisk root?

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!

it's not not-so-well-hidden app.... it's not hidden at all. you can found it under "appearance and personalization" section of retro control panel.

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!

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.

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

Oh yeah forgot that happened (I'm on the Windows version). Fixed it now!
Hello everyone in the XDA Developers community, how are you? I hope that very good.
I come to you because I am desperate with my phone; Since they gave it to me (yes, this phone is a gift) about 3 or 4 months ago (it is a phone from the Sky Devices brand, more specifically the Sky Devices Platinum 5.0M) I had not noticed anything strange, until a couple of weeks After checking my applications in the phone settings, I noticed a very strange app, which calls itself “App Settings”, it seemed strange to me, but I uninstalled it without further ado, but after a while I check the apps and I realize that the app reappeared without prior notice, to which my alarms go off immediately and I resort to installing the trial version of Kaspersky Internet Security for Android, and after running both a quick scan and a full scan, it detects the Trojan in question (attached screenshots below). What I proceed to do now is to eliminate the Trojan in question with the AV, to which I reassure myself a bit, knowing that the AV "neutralized" the Trojan; I'm still normal, using it, when days later, when I see the recent apps, I see the happy "App Settings" running, to which I deduce that the supposed virus survived, to which I resort to different AVs, such as Malwarebytes and ESET, both without throwing me any results. Tired, I let the matter pass and I don't give it much importance. Now we come to today: I begin to notice that the phone is draining the battery too quickly, apart from the fact that there is something that makes it not recognize the SIM (it is not the phone, because before it recognized it, apart from the fact that the SIM is new), I go to Settings to see the applications and I see that the infection has become worse: there are many more apps of its kind, such as a Flashlight call (I don't use external flashlights, I always use the one on the phone), another call " system service ”, and others that by the logo, I deduce that they come from the first one. My question comes in here: what should I do with the phone, given the evidence of infection? I need your help urgently, because if my phone continues like this, with your forgiveness, I will smash it against the wall without further ado, because this virus has me fed up.
Thank you all and I await your responses.
PS: The Sky Devices brand is from the United States, so it can't be that Chinese.
PS2: It should also be clarified that when I eliminate the virus with Kaspersky, more appear again, I attach screenshots below.
PS3: Yes, I know that this question has nothing to do with development, or ROM's or anything like that, I'm just desperate; this virus has me crazy, and I have also published my problem in the Kaspersky Community Forums, also in HTCMania , and nowhere do they answer me, and all I want is to get rid of this damn virus once and for all.
PS4: BTW, I am from Colombia, that is why in the screenshots that I attached you can see everything in Spanish.
