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.

Hello, I was trying to downgrade from N to MM and somehow i lost my system and data partition. I have the custom revolution recovery and i cant mount data or system on the mount menu, also when i try to flash any package it gives me the error "cant mout /datad/system oartition". I also tried to extract system from a original firmware and tried to flash it with fastboot, but it gives me the error "FAILED (remote: sparse flash write failure)". Is there a way to get back my partitions and reflash MM on here, or have i just won a new (very slim) paperweight? Any help would be much appreciated sice im kinda dependent on this phone.
For some reason system is able to mount now... but still nothing in the data partition , it show 0B
i have the same issue
Have you tried to flash oeminfo?
Hi, I have a S8+ and I'm having a BIG problem. I tried to put the stock ROM in my S8+, and now it shows the message: failed to mount /efs (invalid argument) in recovery after reboot, after odin says "PASS"... So I select the option "Reboot System Now", and Samsung Logo appear and nothing happens after this. Stuck!
I have OEM Locked and can't enter in the OS... Help!
Once when I had TWRP I backup my EFS. I have this archives, but I don't know how to zip then to Flash in Odin... (look at attach files).
Help!!!

I received similar error failed to find /misc partition on recovery...however the ODIN said PASS..
I had to install TWRP and install custom OS couldn't get the ODIN to succeed.
I decided to install a custom ROM in my device and what I did was wiped all partitions except 'Micro SD Card' and 'USB OTG', after that I formated data and it wiped all files in my device. Then I tried to flash the custom ROM but I was unable to flash it and an error message pops up - "failed to mount '/cache' (no such device)." I again tried wiping the partitions and all the partitions gets wiped easily exept the cache partition and the same error message pops up. Also whenever I try to restart into recovery, everytime it shows a message "No OS Installed! Are you sure you wish to reboot?"
So please help me out with this problem I can't flash anything at all

TWRP version? Have you tried to flash Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip
to prevent the device from encrypting itself?

I'm using TWRP v3.2.3-1 and I've flashed that zip but still the cache partition doesn't gets mount.
anyone have idea, im also experiencing the same issue. I was trying to root, and it wasnt taking it on my Moto G5 Plus, so i wiped everything except the same stuff, and then after that, any time it tries to mount the cache it fails. It wont mount at all, refuses to check the box. This is my log when i try to wipe the cache only now.

Nevermind, I got it solved,, must have been caught trying to get to the OS, and looping cause there was not OS, and messing things up. Had to make sure i was holding the buttons to go to boot loader every time, but got it working.
Hello,
im new to this Forum. I try my best to give all the information i have.
What happened?
I tried to install the project /e/ os on my axon 7 mini. First I unlocked my phone with tuliptool in edl mode. I found the twrp recovery-image for my device in this guide (https://www.getdroidtips.com/root-twrp-zte-axon-7-mini-magisk/#Download-Files) flashed it with tuliptool to the recovery partition and it worked. But it broke my stock android rom. I only can boot intro twrp - i cant boot android (only shows zte android title screen). Then i installed the unofficial /e/ port for my device with twrp and it worked. Then i thought i could unroot my phone with tuliptool (i dont know why atm i thougt it will be a good idea) so i ran tupliptool lock unlock and my device was locked again. Now i only can access twrp so i undo the locking. After wiping the data partition with twrp, /e/ startet again. Then i thought that wiping the data partition would solve the issiue with not loading /e/ while locked, therefore i gave it an other try. Locking my phone again, wiping partition with twrp and... nothing. So i gave up and wanted to use my phone again so i unlocked it again.
Whats the problem?
Now I only can access twrp, but it wont show the menu. It just autostarts a script and there are no buttons. The script failes after ~10 seconds and the device crashes (error message below). It trys to boot up but fails, so it loads into recovery -> starts twrp -> runs this script -> crashes and so on. Now i cant do anything. It reboots all the time.
What can I do?
As said, twrp starts but with no menu. I have access to edl mode so i rewrote the recovery partition. This does not change anything. I can access my device with adb while it loads twrp. I have a time window about 10-15 seconds until it reboots. Fastboot does not work. (Not available or locked on Axon 7 mini?) If i try "adb reboot bootloader" my phone just reboots into android (well it did before flashing, now its stuck in the loop.) From searching this forum i think i should reformat the partitions, but i dont know how because i dont have access to the twrp menu. If you need more informations like a dump or something, tell me how to do it.
The Error:
As i dont know how i could dump it from my phone to my PC, i had to manual type the Error here...
$Begin
Data successfully decrypted, new block device: '/dev/block/dm-0'
Updating partition details...
...done
Unable to mount storage

$end
This runs fast until "Done processing script file". There it waits for ~3 Seconds. Then the last two lines show up and it crashes immediately.
Ok i found a solution - it worked for me but i dont know why. Its not intuitive but hey, its a workaround.
The problem was twrp couldnt startup anymore because the data partition was currupted (not confirmed, but i guess it was currupted). If you follow any guide, they tell you to go to wipe data inside of twrp and wipe (and reformat) the partition. This wont work in this case, because the corrupted partition causes twrp to crash. Its the script in the post above.
To fix this i used adb while twrp was starting up
Code:
adb shell recovery --wipe_data
This alone wouldnt solve the issue, but it will buy some time. After twrp loads again, you will see the main menu of twrp for a couple of seconds. The time you have on the menu is very limited (5 seconds max) before the script that will crash twrp starts executing. In this time window i managed to set twrp to write mode and initiated the wipe of /data. If you get this far, both scrips (wipe data and open recovery script) will execute, the screen will switch between both of them very fast. After a few seconds it will crash again, but the wipe data script could reformat the data partition properly. After this twrp will work like normal.
I don't know if this problem is specific to my device or model. I dont know if this is recreatable. Im glad i fixed it after five long days, im not willing to sacrifice my device again. I dont know if this is a twrp bug or what happened exactly. If anyone had a clue or needs more informations i will provide them. At least I found a workaround.
I've had my leg h870 rooted for a few years now and I have the bliss 12.4 ROM installed, I'm now trying to update to 12.8 via twrp but it won't allow me to mount /data.
I keep getting the error "could not mount /data and unable to find crypto footer"
I have formatted data in twrp and rebooted into recovery, this allowed me to access the /data partion but once I've booted into system and go back into recovery it won't allow me to mount /data again with the same error I've also tried factory reset via the system but this also won't work.
Does anybody know anything I can do to fix this issue?
twrp is broken, lg bridge worked for me (restock via update error fix)
