[Android Q&A, Help & Troubleshooting] Kevincorella:
Hi

My Poco F2 pro, rooted and encrypted (sadly) decided to auto update, when it flashed in twrp, after reboot I couldnt even mount Data, so I tried to change the file system, but still 0mb, tried try decryp with no luck

I reseach about it, and found that I could dump the dev/block/dm-xx (I trhink so, or to at least recover my data anywhere else but the phone

Please help, any ideas what could or should I do?

~ # cat /proc/partitions

------------------------------

Tried

~ # pull /dev/block/dm-0 /data.img

-/sbin/sh: pull: not found

~ # twrp decrypt 1238

Attempting to decrypt data partition or user data via command line.

Failed to decrypt data.

Tried flashing disableVerity

PD: Lost vendor partition

Any way I can copy the dm-0 (I understood that I could somehow manage to regain my data if I get those files)

Or is it anyway to mount them or any ideas

===================

Would mean the world to me if anyone could help
