I need hepl, I've GM1910 With 10.0.1 gm21AA, I tried to flash 10.0.1 gm21AB from https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424. Unlocked bootloader, download the file and click on flash all. After the reboot i have this message " Qualcomm Crashdump DM-verity deivce corrupted. Force dump kernel_restart". what can i do? I can only reboot on fastboot. Help please.
Edit: I don't know how, but the phone rises up... maybe the force of my desperation... I attached it to warp charge, press vol up + and down + start button many times, after i turn off (I don't remember exactly what I did) and it boot! But now the rom is oxygen os 9.5.3 gm21AA (stock when i unpacked the phone).... Someone has an explanation?
Welcome - Hopefully the last solution - though someone also mentioned this earlier - dont know why people still confused.
If you reached here - "CrashDump Mode it is seems dm-verity device corrupted Force Dump kernel_restart"
dont worry everything is okay - follow below steps
1 - Hold 3 buttons - Power + Vol Up + Down (until phone turned off)
2-Press Power + Vol Down - go to fastboot
3-Power of by selecting the correct after turned off restart the phone, if doesnt work retry... solution is there
If after step 2 you not reaching fastboot mode - then choose between the menu given by system to reach fastboot mode then follow 3rd step.

hello brother. i am stuck here with. i have tride your words but not working.
qualcom crash dump mode
dm-verity device corrupted force dump Kernel restart
what can i do now
Hey sorry to bother, Ive run into the same problem as OcazPrime but in my case it is the oneplus 7 pro that shows that message. I dont know how he got the phone to boot to twrp but mine keeps going back to that error when i press vol+ and power button.
I really am loosing hope that ill be able to unbrick it, i tried every method that i found and got nowhere
what if fastboot mode doesnt work
You need to force reboot to recovery. In Dump mode,what if fastboot mode doesnt work
i`m holding volume up volume down and power button at the same time
and it will just restart to get again crashdump mode
Yesterday i had same problem, after few hours i managed to flash using MSM tool
but not every try works for me ....
it`s always going again to dump mode
