[ROM][8.1.x] Official LineageOS 15.1 for Lenovo Yoga Tab 3 Plus (Wifi/LTE)

[Quallenauge]

Introduction

These builds only support the Lenovo YTX703F and YTX703L targets.

Installation instructions

1. Unlock your bootloader and install latest TWRP. Some further indications on how to do this can be found here.
2. If coming from another ROM (including unofficial cm14), do a full wipe of the system and data, cache and Dalvik cache.
3. Install your downloaded zip file containing this ROM.
4. Make sure your device has the latest supported firmware package (S000973_180524_ROW). If it doesn't, you may flash the attached firmware zip. This only needs to be done once.
5. Optionally install Open GApps (tested with ARM64, 8.1, nano variant).

Known Issues

• After installing from unofficial to official a data wipe is needed.
• Speaker auto-rotation is off by 90 degrees, and has currently been disabled.
• The Facebook Messenger app (com.facebook.orca) reads data from the camera sensors rotated by 90 degrees. To the best of my knowledge, this is an application bug, since it doesn't observe our camera HAL settings. Other camera applications work fine. Please use Facebook Messenger Lite if you need camera.
• Expanded Desktop feature doesn't work -> display isn't turning on after standby. See here for details.

At the moment we do not have plans to support unofficial builds.
Automatic data migration from unofficial cm14 to official lineage15 is technically possible, but we never attempted it before and therefore it might be error prone. You should be best served by backing up your app data on your own (e.g. Google cloud) and restoring after you clean wipe system and data partitions and install lineage15 and gapps.

That's not problem, I use NTFS with bigger SD Card.

No it does not support exFAT.

Thanks a lot for official version.
There is flashable Dolby Atmos for OREO Roms with LOS - can it work? Or is it completely impossible at this time? (I know it's not easy)

I don't know, I'm not a Dolby Atmos guy.
Of course you can try, but personally I wouldn't expect much.
What are you trying to achieve with Atmos anyway? Maybe I can help you in another way. Because you know, I use the device too for videos and music, and the speakers don't even sound half bad. Especially when you compare to some other devices running AOSP-based ROMs that lack the OEM customizations (**cough** devices with NXP TFA amplifiers **cough** where the audio in Lineage is really cringy).

After i installed and used it when the screen lock and i wanna unlock it i have to long press on the bottom and sometimes it does not unlock

Can you rephrase?
Is it the power button that fails to register some presses, or your screen has issues turning on (delayed or not at all)?

 

[waleed.star99]

Sometime delay ( time ) to get it on and and sometime i have to reboot and even it wont open and i check the wake on plug when i charge and discharge the tab the screen wont turn on even if i press the power bottom ( how i reboot i long press the bottom and the tab reboot )

 

[vladimiroltean]

The next time this happens, could you please activate ADB, connect the tablet to a PC and send me the dmesg on pastebin?

 

[waleed.star99]

Ok i will

 

[vladimiroltean]

After you capture the logs during screen power-on failure, please send me another dmesg taken immediately after you reboot as well. I want to check some messages printed early during the boot process and I want to make sure they don't get overwritten by newer messages if you keep the tablet open for too long.

 

[waleed.star99]

i rebooted waited till the screen off i tried to on but nothing then i captured these

I'll check the stock backlight driver tomorrow again. We probably missed something that is LCD ID specific.
