I'm pretty sure phone's Stock ROM comes with 3 vbmeta images, as these are: vbmeta.img, vbmeta_system.img & vbmeta_vendor.img. If that's true then on all these 3 vbmeta images the disable verity ( AVB ) flag must be reset in order to flash a Custom ROM, not only on the one named vbmeta.img.

Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_system vbmeta_system.img
fastboot --disable-verity --disable-verification flash vbmeta_vendor vbmeta_vendor.img
where all 3 vbmeta images must get derived from phone's Stock ROM.
there is no files in (umidigi power) but then i download (umidigi power 3) there is the files.

Hi guys... Need your help... I am not sure what i did but i cant seem to see any storage when i go to advanced settings. Using twrp 3.0.2. attaching the files..

I am using yutopia sambar phone.. n I jus want to install custom rom. When I install using fastboot to install rom, it does successfully but when I boot it up, it just hangs at Android is starting. And when I check thru twrp, it says that there is no os installed. I think I can't install the os because there is no system partition.

And when i click on the mount system, it does not get untick. Currently, there is no os in the phone. Appreciate your help on this matter.. been going crazy for the past 3 weeks.. trying to figure out why is not working...

I just want to install original ROM and just want the phone to function. Hope you guys can help me out here.

Thanks in advance guys..

?????????

I've literally owned dozens of Android phones this past 6 years and all of them requires wiping system to install a new ROM, so I did the same with my (now bricked) OP7Pro. Care to explain that??

Is this solved? if not, try to download its original firmware and download the "fastboot" one rather than the recovery one, after download , extract the zip after extracting , there should be a flash_all.bat just double click it and it will install the firmware

I mean, were there no errors when doing the flash_all.bat?

I tried all possibilities and flashed Stock ROM both in Fastboot and Recovery mode but no luck, even tried old stock ROM as well. Finally, after researching I think Encryption is the whole culprit for this boot loop.

How to decrypt? error is " unable to decrypt FBE device"

I tried below 2 steps to decrypt, but no luck again boot loop ....any suggestions?

1. Formatting Data by typing "yes"
2. Formatting data partition from f2fs to ext4

    download this https://github.com/phhusson/treble_...d/lineage-v21/system-arm64-aonly-gapps-su.img

    1. Perform a factory reset within TWRP.
    2. Transfer the system-arm64-aonly-gapps-su.img from your PC to your device’s internal storage where TWRP can access it.
    3. on TWRP tap Install
    4. choose install image select system-arm64-aonly-gapps-su.img install it on system partition.
    6. access rebboot to fastboot via TWRP (if your TWRP don't have this you can go fastboot by doing the hold vol+ method)
    7. type on fastboot flash vbmeta name_of_vbmeta.img <~ you may aswell disable dm-verity while you're at it
    after that type fastboot reboot

    since you can install stock rom inscase something wrong happen there's should nothing go wrong so ... May the odds be ever in your favor .
