Interesting!
this must mean that both non-pro and pro use the same kernel, they both might basically be the same device with a few slight hardware tweaks

Hi! I installed TWRP on bv9800pro, but I didn’t manage to disable userdata encryption. I edited both fstab.mt6771 files in both /vendor/nvdata/ and /vendor/etc/ and formatted userdata from twrp, but after rebooting encryption always turn on. In folder /vendor/etc/ after reboot, the 'forcefdeorfbe' parameter is always restored. Also, I can not recommendet reset the phone if the native recovery is deleted from the phone, otherwise, instead of resetting, there will be a constant download of TWRP.
All the same, everything turned out.
To disable encryption, you need to install this patch  Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip (https://androidfilehost.com/?fid=4349826312261749617) from under twrp, then format userdata, you can immediately install Magisk. EVERYTHING WORKS!!!
Thanks! Smile

Hi,

I tried to flash your TWRP on a non-pro BV9800, but run into errors during flash procedure

could you assist on that issue?
