"dm-vertity failed - need to check DRK" after downgrading from cm13 successfully

"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

Connect your phone to computer. Install Samsung Smart Switch on the computer and initiate a firnware reflash trough it. It is official samsung service so it will automatically download the latest official firmware for your device and after that it will flash it no matter what you have done to your phone as long as you can boot it into Download Mode.

Galaxy S8 Stuck on "Powered by Android" Screen After Android 9 Update.

Hi guys I own an S8, SM-G950F. The previous software I was on was Android 8 U2 (can't remember exact one). I flashed the new DBT Android 9 software via ODIN (using CSC, not home CSC). However the phone stays in the "Powered by Android" screen and does not go any further.
I can go into the Samsung recovery mode and have tried wiping both the cache and data/factory reset but this seems to make no difference. As an alternative I have tried flashing the Android 8 files (with bootloader U4), which is successful in ODIN but shows "No command" when booting.
USB debugging was also turned on before applying this update.
Other info:
FRP Lock: Off
OEM Lock: Off
RP SWREV: B:4 K:3 S:3
Any ideas what I could do?
Thanks.

Thanks for your reply. I have tried this although it does not work as the boot loader version is now at V4, whereas the previous software I had was V2. I have tried flashing other Android 8 software with boot loader V4 but it goes into the “No command” state where I can’t access the recovery, only download mode is available.

I also am seeing the same message in recovery mode. Also in odin mode(download mode) there is extra lines of text. Although in saying this the s8 boots and seems to function as per usual. The storage used from stock firmware is 12.4 GB... Is this normal??
All I am wanting to know is "is this normal for the exynos galaxy s8 running One UI, android 9" ?
or Did I Download a dodgy Rom?

How can I fix this?

Is there any update on this? I have the same issue as post #11 on a Samsung A8 sm-a530w.
Any help would be much appreciated.

I've got the same issue on a G950F.
I bought new (sealed, G950FXXU5DSFB), and tried to flash combination file G950FXXU5ASF1 . This did not work. (no boot).
So I flashed what I thought was stock rom matching CSC.
(AP_G950FXXU5DSFB_CL16290088_QB24491245_REV00_user_low_ship_meta_OS9.tar )
The phone boots and operates fine, except for the same message you guys are getting in recovery, as well as a message about no OTA updates.

WHAT SHOULD I DO?? TO GET BACK ON STOCK??

You'll need to install stock firmware via Odin. You can download this G935FXXS7ESK7 from sammobile. But it's slow so look for somewhere else.
Press and hold power, menu and volume down button to get into download mode. Then use Odin to flash the stock firmware. Hope this helps

have binary u2 there is no combination file on u2 for samsung g570f can i install any combination file? for my phone?

I have binary u7 for my SM-G935FD and there is no combination file of u7 sadly . I also have FRP lock on. This happens when I try to boot into recovery mode. And I cant boot because a blue android face comes up and the same thing happens.

J5 and u7 are not s7. Download the original firmware and install it.

You only need the AP Firmware file.
How to flash Stock
Then root or install custom roms.

did you find any solution ?

problems with the G570F help

well first i want to say hello, i will explain my problem how started i wipe efs from my phone via z3x box because I was trying to fix imei, baseband, and no service sim problems. I have an unknown and i'm failed the idea was stupid and i did a reboot and i faced some problems in frp has locked bootloader i think its text is red i downloaded firmware rom stock from sam mobile and did flash on odi, but I downloaded the last version and binary U2, this is the file name G570FXXS2CSH1_G570FOJV2CSI2_TUN then the phone turned on and entered me on the recovery mode and showed me " installing system update " and then the "Erasing" and then he restarted alone and it appeared after him "No Command" I pressed the volume up button and the button power so that I see what I'm wrong, I tried to find my combination binary u2 and i didn't find only binary u1 and i have frp lock ON so i can't install root or TWRP on my phone and also i could not to boot into the system so I searched on google and found a file named "SM-G570F U2 Android 8.0 FIX DRK - dm-verity Failed Frp ON RMM ON.tar"
I knew that this file would fix my problem is " E:[libfs_mgr] Couldn't create verity device!" I'm flash my phone and put this file in the place of BL and also put the AP file system which I think is 2 GB and when he succeeded in the flash process my phone did a restart and showed me the SAMSUNG logo and entered me to the system, but another problem appeared to me, that the touch does not work, I cannot press anything if I hold on the power button, and i'm see RESTART and SHUTDOWN appears to me, but I cannot even click on them. I thought that this problem is from the file that I flashed to the location of BL, perhaps, also I am unable to enter recovery mode unless I flash 4 files again but my question is there is another solution To fix my phone? I want it to come back :crying:
Question: did u download the firmware stock and the same model phone?

Try reflash stock, then TWRP if possible. Otherwise no hope, also stop spamming in your threads, no one will help you with this attitude. Try to maje the thread as short as possible cause no one will want to stay and read all this stuff.
