Please give me some more time, I'm very busy these days , and the little free time which I have will be dedicated to LOS 17.1.

I'll send a PM as soon as I'll be ready to help you ... Of course I'll just try, I don't promise to find a solution for sure. Thanks !
Much appreciated and no rush! If it helps at all the last build to work with the Bluetooth keyboard was 2020-11-17.

This is just to say thank you for your great work on this ROM! I am using it actively on a daily basis. I have even repaired the cracked display. Can't wait to check the new release :)

Flashed today latest build and is way more better than other releases. Everything goes smooth.
I found only 1 issue till now: when device is shutting down, screen still stays on. I do not know if it has already been reported.

If you have BTV-W09 you should try to flash also the new boot image for your device, because after your issue it looks like you are still using an old kernel where the encryption it was enabled .


EDIT:
On older releases like the one you use it, encryption was enabled in kernel but disabled in fstab, and on the new builds, encryption was disabled in kernel & enabled in fstab. If encryption is enabled in kernel & also in fstab you will get the same issue like you have right now !

I guess there was a major upgrade of the kernel from October to January and in this case a clean install is needed !

You may be able to help the developer by pulling a logcat. That can be done via ADB, or using Logcat Reader app, which allows you to download it. Then zip up and post for review.
If I use the Logcat Reader on the LineageOS 15.1 rom, will it generate a logcat that you can use? Or do I have to go back to the stock rom?

Please, check post #766 once again, it looks like you didn't understand.
I have tried back EMUI 5.x again but with no success. I reinstalled EMUI 5.x's old TWRP to restore it, but that TWRP doesn't work. Right now I'm still using TWRP-3.3.1-0 / LOS 15.1. can you guide me step by step to go back to EMUI 5.x and get INFO? Thank you very much
