"dm-vertity failed - need to check DRK" after downgrading from cm13 successfully
Hi this only happens after playing with the EFS Folder as it is needed when you want to dawngrade . i heard that that some tools like ultimatemultitool can fix the prob on s6 but any help on note 4? plz
dm-verity is a checksum on the system partition if any file is touched or deleted on the system partition
the checksum fails and recovery says dm-verity failed
it doesnt mean nothing just flash a full stock image or custom recovery

Hello, I have a problem. When I installing supersu from SD card (I have TWRP), operation failed:
E: failed to verify whole-file signature
E: signature vertification failed
Please help, I need root
Its mostly a recovery issue. What twrp do you have? Twrp is doing verifications of the files being installed. I never had that problem on TWRP 3.1.1 by lemlis. Try installing from internal storage or download a new Su zip.
Dear all,
I tried since yesterday to root my S8 Exynos (G950F). My phone is crypted and when I try to root with magisk via TWRP, I have errors to access to datas. When the system boot, I have the error unable to restart your phone. the integrity verification has failed....
Then via TWRP and the shell, I made a copy of the userdata partition on my computer (the crypted partition), then I wiped my phone, I flashed the DM Verify Disabler and then Magisk via TWRP, until then, no problem, I was root but with an empty phone.
There, I uploaded my copy of userdata partition into my S8, I boot the system and always the same error of integrity verification failed...
Now, my phone works always good (I flash the stock ROM via ODIN) but I haven't yet the root.
Is there a way to root the S8 without lost the datas ? A kind of APK or something else ?
Kind regards,
Lau

You need to reflash twrp in odin and boot into recovery (TWRP) before the phone boots the system. Id uncheck auto reset in odin and when its done flashing twrp again boot right into it. From there you want to select to keep the system read only, and then flash the DM Verity Disabler. After thats done flashing, your phone should boot up normally without seeing the integrity failed message. Its important that you boot right into twrp (recovery) after odin flashes it, if not you need to reflash twrp in odin until you successfully get into recovery before it boots your system.
I just tried 2 times this procedure, when I flash the no-verity-opt-encrypt-5.1, I have several error messages like Failed to mount '/data' (Invalid argument) or Unable to recreate /data/media folder or Unable to mount storage and Unable to mount /data/media/TWRP/.twrps.
When I boot up the phone, I have the same error of integrity failed message and I have to flash a stock system and boot img

You have to wipe data otherwise it won't boot, there's no way round this unfortunately

Previous poster is correct. Wipe>Format data>yes> in twrp then you should be good to go.

Tablet [SM-P610](Android 11) was successfully unlocked & rooted.
However TWRP flash (using odin) failed!
I get the following error after flashing 'twrp-3.6.1_9-0-gts6lwifi.img.tar'
and tablet halts on boot!
"Error Verifying vbmeta image : invalid vbmeta header (6)"
Any suggestions as to how to fix this and flash TWRP successfully?
Any specific [SM-P610] vbmeta / TWRP Recovery .img.tar download links ?
Thanks!
Do NOT use TWRP, the current version is unfinished and won't ever be finished anytime soon. Use Lineage Recovery instead.
There is twrp for Android 12 ,, will be in comments iofntwrp.post
