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.

[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!

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

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.

Oh yeah forgot that happened (I'm on the Windows version). Fixed it now!
If anyone is still (trying) to use daydream on normal devices, I'm going to share my experiences with getting it to "work" in a redmi note 4 (sd625 variant), along some other problems I do still face.
First of all, you need to know that daydream is designed to have always reprojection on, if you don't know what that is, take a look at this. This means that unless you have an oled display, with their inherit characteristics (low persistence), or an lcd that's capable of doing 90hz or more, you're going to experience a lot of motion blur with fast head movements or circular movements. That's not a bug, it's how it's supposed to work, that's why if you go check the list of official compatible daydream phones all have oled displays. The benefit of that blur is the buttery smooth head tracking, use it for 5 min, and you won't be able go back.
Once you have prepared your stomach for the ride;
1st: You need a rooted device (easiest method is flashing with a custom recovery the latest magisk version). You might be able to avoid rooting if somehow you manage to modify the files in the next steps, but at least for me, to access those files I needed root permissions.
2nd: Go to the play store and just search for daydream (do not install it), if you're able to see the app, you could jump to the next step. If you don't, download a file explorer with root capabilities (I personally like fx explorer) and paste the "android.hardware.vr.high_performance" file attached to the following route;
Code:
/system/vendor/etc/permissions
.
In this same folder you'll find the handheld_core_hardware that's mentioned in other guides, you might be also capable of getting it working by editing handheld_core_hardware, just like the old tutorial said
3rd: In order to get most of the daydream apps to render in SBS mode or even open, you need to spoof the id of your device to one of the certified ones. This is exactly the same step contained in the tutorial above, but at least in my case, once I opened the build.prop in the /System folder, I didn't saw a "ro.product.device", but a "ro.product.system.device". What I did was modify the latter by changing "mido" (the name of my device) to "walleye" (pixel 2) and adding a new line with "ro.product.device=walleye"
4th: Restart your phone and install Daydream, google vr services, and daydream keyboard all three from version 1.13. Daydream
Google vr services
Daydream keyboard
This version, along with 1.14 are the last ones that at least in my phone don't distort the aspect ratio, making it all squezzed. Version 1.14 has some handy implementations but worse performance and the lack of a developer option that I find really interesting for our unsupported phones that I will mention later.
5th: Now that's all installed, open the app and it will tell you that it need some permisions to work, press cancel and it will exit itself. go press it again and this time you'll see the daydream menu, swipe to the right to open the side menu, go to settings, VR settings, and if you don't have developer options, press compilation version several times to make them appear. Once you're inside those developer options, check the "skip VR entry screens". This is essential for all of us that don't have nfc, otherwise we wouldn't be able to run any app.
6th: Go to to visor and select your daydream version, bare in mind that if want to use a controller, you'll need to chose between gen1 and gen2, as cardboard custom profiles gray out the controller.
7th: Go to the controller tab and press and new controller, you'll be asked to fix the permissions, by enabling bluetooth, gps, and location you should be good to go, but considering we are using google play and google already knows all about us, I would say go ahead and try go give all permissions, just in case some specific app requires them.
Now follow the tutorial and the controller should pair... or maybe not. This is one of the problems that I don't know how to fix. The controller appears to be paired, as the light no longer blinks, but the daydream app doesn't detect it. At least for me, I couldn't get it to work in android 7 or 9, android 8 I (think?) I managed to get it working, and all android 10 roms I tried worked fine. I suspect it has something to do with the bluetooth settings, as it's a low energy device.
8th: You're good to go. Depending on your display and calibration, you might want to download an app called sa2ration that allows you to boost the intensity to get a more vivid image, I personally use 1.25 and it works wonderfully. Bare in mind that this works system wide, you could toggle it on and off whenever you want, and the settings don't reset with phone restarts.
---------------------------------------------------------------------------------------------------------------------------------------
Now that everything is "working", If you want to avoid the blur, and the app you're going to use is capable of holding a steady 60fps, you could go to developer setttings, and tick the "Force undistorted rendering". This will supress most of the motion blur at the cost of smoothness. This for me also reveals another problem, the resolution/dpi settings, as the image "bleeds" outside the supposed rendering area.
@Retrete: THX for your hints.
Any xiaomi/redmi or oppo/realms device you can recommend? Is the experience as good as on official daydream phones?
I remember that on my axon7 the amoled needs to be switched to low persistence mode via fw command.

Hello, I have bought TV Box from China,
Model Vontar X3 Amlogic S905SX3 4GB/64GB Android 9.0.
I have a few problems with this TV Box:
1. I cant install any apps from Google Play Store. I dont know why...
2. There is problem with overheating.
3. Software installed in tv box comes from 2018 year. There is newer version on local disc. Should I update to new version?
I hope that someone help me
Regards
Hi, you may need to update google play services and the play store, you can find the apks on apk mirror,
What are your overheating symptoms and temps?
Where did you obtain this updated firmware, issue being sometimes these devices are clones and dont work properly so there is always a small risk when installing a firmware, I would reccomend using a usb A male to male cable & usb burning tool and read about Mask Rom Mode as this makes these devices recoverable from a bad firmware or flash, means you can try custom roms for S905X3 too, often the aweful factory firmware is aweful, I have my own android 6 s905x box running the official Android 9 Mi Box Firmware (with my modifications) and it makes these devices very usable, performs like a proper mi box, no lags ect, point is firmware can make a world of a diffrence

As my threads, topics etc here are unreachable for the moment (due to the forum changes) please go here to see about the playstore problem (Note2 of 1st page): https://forum.freaktab.com/forum/tv...-transpeed-x3-air-bqeel-y8-max-amlogic-s905x3
For the overheating just place your box above a USB fan base. That is what I use for all my TVboxes and I get a temperature 10-15 degrees Celcius lower, which is more than enough. You can make it by yourself or buy a ready made.
Installing also a custom rom will give you "another" box (meaning with more capabilities).
Have a look at my custom rom, especially if you need a preinstalled Magisk and TWRP.

Hello, I ve found solution for overheating problem: Its Vontar C1 cooler. I get a temperature 20-25 degrees lower. It should be enough.
How to update google play services and play store in Vontar X3?
I can make update here: Settings -> System Update. I have XR1.180610.011_release_keys(20200822_0033). X - I dont know what sign is before R.
And there is another problem: some channels in smart TV are in 16:9 forrmat. In Vontar the same channels are in 4:3 format.
And frame is cut on the left and right. So for example, number 123 - I see only 23. Just like XR1.

Probably you didn't read my note 2.
Install the latest app of Playstore from apkpure https://m.apkpure.com/google-play-store/com.android.vending
Reboot and try again.
Also try in addition this : Playstore-Settings-version number and click upon the version number 7-8 times. You will become a developer and probably get even newer updates.
You may have to reboot again and click once more upon the version number!!!!
As far as your mother I have ginen one to my mother (she is 87 years old !!). Having Launcher Square Home she is happy/and easy to use !!!

First of all look at Settings-Device Preferences-Screen and look/change what it is in "Screen Resolution" "Screen Position" (you can make smaller/larger the image shown).
Also you may have to alter something in your TV preferences.

Thank you for solving problem with Play Store. Works great and perfectly.
About screen - I dont have "Sceen" option. The only option with screen in the name is " Screen Saver"
Anyway. Thanks again.

Hello, I think that you must update your play store, it happens a lot when Chinese dud taps a standard google android system. It's outdated and reconfigured for first use. Chinese craps. One thing you need to do is update play store as a .apk . Download it on your PC and put in SD CARD or direct with USB cable and transfer and install in device. Restart system and you should have a updated play store and no limitations.
I know this is a month old topic but maybe it will help others.
Hi guys,
I recently dug up this ancient piece of hardware wondering if i could get it back into a usable state again, as expected the normal windows 11 edition was almost unusable. So i created an ISO based on https://tech-latest.com/ghost-spectre-windows-11/. Its completely stripped down version of Windows 11 and has an intuitive command line tool to install your needs.
NOTE: As with all custom windows builds be careful about putting in personal data, i don't know the sources, I just added the drivers.
Bugs:
All drivers are already installed, only thing not working is Camera... but let's be honest... that thing never worked please SHARE if you found a solution
Instalation instructions:
Download iso here: https://mega.nz/file/5YwHyRaR#kgjrw2iQI23EvW2V6ReqlUu1-Rs9GT60zzhPXSNU-CA
Download Rufus here: https://rufus.ie/
1. Use Rufus to create a bootable USB
2. Dont use any of the Rufus options to customize your install
3. After creating the USB connect it to the tablet through a USB OTG adapter
4. Press F2 while booting up, select to boot from USB
5. Wait till in the windows install screen (this can take up to 15 mins).
6. Go through windows installation (can take up to 1 hour)
7. your pc will automatically reboot
8. set up admin password
9. connect to wifi
10. open GHOST TOOLBOX on the homescreen.
11. you'll see a menu with numbers, type in the number of the feature you'd like installed and it will guide you through the installation.
Tip: start downloading a browser first
yeah I know, the install time is insane. But at least you will have a semi-usable tablet.
MAKE A BACKUP OF THE ISO( IT'LL BE ACCIDENTALLY DELETED IN THE FAR FUTURE).
THIS ISO WILL ONLY WORK FOR THE FIRST EDITION YOGA BOOK WITH WINDOWS 8. DONT SEND ME A DM QUESTIONING ME IF IT'LL WORK ON [INSERT GENERIC CHINESE BRAND]
Good luck and may the odds be ever in your favor
“I installed Ghost Spectre Compact without DEF and I would like to add it. Can I upgrade without reinstalling?” Thanx
You saved my life! Your ISO was very helpful, and the solution you provided was both light and stable. My yoga book was broken and wouldn't boot, but now it's working very well. Thank you!

Thanks, it's good knowing I didn't do it for nothing. I mostly created it for myself but was so surprised with the usability that I decided to share.
Tbh I'm not really sure if this ISO is compliant with the MS Terms of Service. So I would recommend to download a backup
At least this ISO makes the tab usable and I'm happy I could share this goodness
Btw, I discovered that the camera's are not working with this iso. Please let me know if you found a solution
just working with superlite and its not good for audio production like Pro Tools my CPU not working with all cores even if i want to change to make my CPU work with full core from
System Configuration in windows >boot>Advanced option
is grayed how can i fix this?
and if i want to go with compact is any way to ypgrtade without losing setup plugins and configuartion installed before to make the system

I attempted to install Android and Windows Lite on my slow Yogabook, but it resulted in it not starting up properly and being unresponsive to touch. However, with the help of your software, my old sluggish Yogabook now looks great and runs smoothly - almost like a brand-new device. Thank you very much for your assistance.
about the camera, check on setting, camera VO2740 is working well for me. You can try to update the drivers (instead of the battery driver)

This is weird. Tbh I never looked into that and the perceived speed of the device is faster. Maybe there are some changes in this build that affect the multi core performance? Maybe the lack of TPM and windows 11? Is hyperthreading and or virtualization enabled? And have you tried it on the normal version of windows 11 and was it different? It could also have something to do with the limited CPU. I'm busy with my graduation internship, so don't really have time to delve into it myself
