    As a test of compatibility and speed, I generally run Geekbench 5 after each new ROM version installation. Today's run went fine, 348 Single Core, 1281 Multi Core which is pretty consistent with past performances.

    BTV-L0J, Dirty flash not boot, but I was easily able to recover it.

    The method​


    Back up the data with TWRP.
    Wipe Dalvik cache, Cache, Data, System, and Vendor.
    Flash the latest ROM and Gapps. And boot system.
    Go to the home screen without internet connection and without logging in to Google.
    Restore the Data with TWRP.


    For Magisk users

    Back up your data with TWRP.
    Wipe the Dalvik cache, Cache, Data, System, and Vendor.
    Flash the latest ROM and Gapps. And flash Magisk.zip, boot system.
    Go to the home screen without connecting to the Internet and without logging in to Google.
    Install Magisk.apk. If you used Xposed, install it too.
    Restore the Data with TWRP.

    Finish. No need to register your Device.

    Hello !

    There is a new Update Of LOS 17.1 into OP !

    Thank you Surdu,

    This release is excellent. Vanced Manager works well again. Reddit videos seem to work again. I also had an issue with Arte application which didn't show thumbails. It works now.

    I don't know yet if I still have issue with Wifi which sometimes disconnects for unknown reason. I didn't have this issue with the stock ROM.

    Now, I will try to change the battery to increase again my tablet lifetime.

    Thank you again Surdu.

    Is it even possible to make the camera work or should we just forget camera when it comes to android 10 on this tablet?

    @surdu_petru Did you build the rom? I'm trying to get into rom building but i just don't get it. How did anyone get a real personal customized rom when they just hit 4 buttons and wait until the "building process" is done? I mean how can anyone customize a rom in that way? Am i just dumb? :O

"media.camera" not started , also "dumpsys | grep 'media.camera' return only "media.camera.proxy" and not the both services ( 'media.camera' & 'media.camera.proxy' ) as would have been normal ...for moment we can forget camera on Android 10 as I have no clue how I can fix this issue !

      Thank you bro. I hope you will update this rom 😁😁😁
      Yes, I'll update for a few years 😊

      I've been having a problem of Chrome freezing frequently since March or April. Once it freezes, it can be released by going to the home screen.

      This problem is not resolved in the latest build and also occurs even after re-installing Chrome.

      This problem also occurs in Chromium browsers such as Vivaldi, but not Firefox, so I suspect that the problem is not caused by the ROM, but by Webview.

      Does anyone else have the same problem?
      Chrome I rarely use it but I do use Brave and I haven't noticed any usage problems. I think Brave is also built on Chromium.

      I will flash the latest ROM tomorrow, and I'm using the previous version right now. Chrome still stops when I'm browsing, so I have a plan below.

      1: Dirtyflash and use Chrome for checking. If it doesn't stop, OK.

      2: If it does stop, I'll install it from scratch.


      Anyway, thank you for the update!
      Yes, dirty flash over previously update and I have 0 issues !

      Android 10 is coming on your Huawei MediaPad M3 8.4, Kirin 950 SoC with the LineageOS 17.1 !


      Devices Supported: Huawei MediaPad M3 8.4 : BTV-DL09; BTV-L0J; BTV-W09


      LineageOS is a free, community built, aftermarket firmware distribution of Android 10 (Q), which is designed to increase performance and reliability over stock Android for your device.

      LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

      All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.


      Warning !
      Installing a custom ROM on your device can sometimes be difficult and also with unwanted consequences! Therefore, make sure that you understand exactly what risks this operation entails - you are the only one responsible for all actions taken on your device.

      Reporting Bugs
      • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
      • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
      • If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
      • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
      Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.
