Hello,
Its been a long time since I last flashed a phone/tablet. I've read the OP and I have a doubt:
Under downloads there is a file "only for wifi devices". My tablet is a BTV-W09 wifi only so I understand that I need that file, but when do I flash it? Do i flash it instead of LineageOS-17.1-BTV_2022-05-14.zip??
Im quite confused, thank you for your help!

Yes, install the .zip archive and after that you should install the fix for BTV-W09 wifi .

I had a few runins over the months with the creator's behaviour which I still find weird but I really have to say, the ROM works great, gave my M3 a second life. Quicker than stock, less batterie drain and all in all running very good.

Only two flaws:

- camera not working, which is common knowledge and not important fpr my use
- as with stock, no Netflix- and Disney+-HD streaming possible because it is still Widevine Level 3. Is this a hardware thing or can this be corrected by Software I ask myself?

If you need camera working you should switch to LOS 15.1 as it's working there !
Yes, our device it's Widevine Level 3 - so we can't do anything here .

Thank you for the understanding !

All it's working here without any issues if you can read and understand the installation instructions from TWRP and also for LOS ! Your issue will be fixed after data format into TWRP, that's why there are installation instructions, to be read and followed step by step

* format data
* reboot into twrp
* copy LOS 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.

    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.
