you're to unlock bootloader of your device and flash empty vbmeta along with twrp using fastboot

(22-03-2020, 02:22 AM)lypsky 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.HI! I installed the patch and touch didn't work anymore, but in the TWRP. So I reflashed boot.img and patched witch magisk (in this way touch works but I have the userdata partition encrypted). Is there any other way to get userdata decrypted?
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!

Hello made all the things you proposed except the point that I flashed the autoported TWPRP (https://www.hovatek.com/blog/auto-twrp-p...-spd-v1-4/) before trying to flash vbmeta.
seams that there is no vbmeta partition, I also can't witness this partion in the SP flashtool
actually I am not able to enter recovery mode, devices says its in "orange state" after unlocking the bootloader, but the devices boots up normally
any further suggestions?
Thanks in advance
