Hello, I want to fix a friend's device with the "dm verification failed"
When the phone is powered on, it loads into the stock recovery with the dm verification failed alert! I got to odin mode and he already got "FRP Lock ON!" before the device started the issue.
I have flashed a stock MM 6.0.1 and after successfull flashing. It tries to boot and complain of DRK missing and that it should be installed first.
I can not flash Custom recovery or CF Autoroot as "CUSTOM BINARY is blocked by FRP ON"
I's there any other thing I can try to fix this?
Thanks.

So guys, bought this phone used 3 days ago. The phone was rooted and the fingerprint scanner was not working giving some error. So I decided to get the phone returned back to stock.
I flashed the G925TUVU3DOJ7_G925TTMB3DOJ7_G925TUVU3DOJ7_HOME.tar file via odin 3.10.6. All files were successfully flashed with pass message but now i am stuck on the boot screen at s6 edge logo. I did a factory reset and wiped the cache but no luck.
The recovery shows an error of dm-verity verification failed... as well in the bottom. I can get the phone in download mode. The current binary is samsung official but in system status it still says Custom. I tried flashing G925TUVU2COF6_G925TTMB2COF6_G925TUVU2COF6_HOME.tar but it doesn't let me flash it as I read i cannot downgrade.
I have tried searching at different places but couldn't seem to find any appropriate solution as most of them are for cof6 or cof8 firmware. I would appreciate a lot if someone could guide me step-by-step procedure to get my phone working back.
Note: I think that the phone IMEI was also repaired as the IMEI on back glass and in the system does not match.
I also cannot get any assistance from t-mobile as I live in Pakistan. I could not attach shots as i have less than 10 posts so writing the status:
In download mode:
PRODUCT NAME: SM-G925T
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: OFF
Secure Download: Enabled
KNOX WARRANTY VOID: 1 (0x0301)
AP SWREV: B:3 K:2 S:2
Recovery error at the bottom:
dm-verity verification failed. . .
Need to check DRK first. . .
It sounds like there may be an issue with your IMEI. I think you should try and use Smart Switch on your PC to do an emergency recovery. It will completely wipe the phone and reset everything to how it should be.
Emergency recovery requires the serial number in order to proceed. You can get that by going into Download mode but before you hit Vol Up to continue hit Home instead. It will show IMEI and Serial Number (the bottom number).
Samsung Smart Switch for PC can be downloaded from Here. Install Smart Switch. Start up Smart Switch and click more in upper right corner. If you don't have the Samsung drivers installed you can install them from here. Or if you would like to reinstall them.
After you are done with drivers connect your phone to the PC and click more and click "Emergency software recovery and initialization" (the first option). It should ask for your serial number. enter it and it should start doing it's thing.
Hopefully this works for you and good luck.
Thanks for the fast reply. I flashed it using the smart switch software. The program completed successfully but still the same result. Stuck at boot logo and same dm-verity error in recovery

Thanks alot @jayshaa. Finally booted up... Hats off to you man...!! :good:
Sorry to disturb again... Today when I restart the phone, I couldn't pass the boot screen as I gave me the error Custom Binary blocked by FRP Lock. Frp lock turned on automatically and now I am again stuck at the boot screen. I again flashed the stock rom but the frp lock is still on. I couldn't flash the kernal as well because of this lock.
Someone please guide me to turn this frp lock off and get my phone working again.
Need to check DRK first. .
This error means at some point your efs probably was wiped meaning the drk was wiped... unless this is fixed the phone will boot loop everytime you update unless you flash a modified kernel...
So how do I fix that or turn frp lock off?
Anyone???

That can only be turned off via Developer Options in Settings. If you flashed a custom kernel then you cannot turn it off because you will boot loop. You must flash stock kernel. Or just reflash the stock firmware package.
After you get back to stock. get to developer options and turn off the FRP lock. Then you can flash away.
Edit: I'm editing this to show what I just posted in a comment elsewhere. I really wish someone would help me because I can't get answers.
"Can you please help me? I'm so lost. I've been at this for quite a few hours, so I'm sorry if I'm unclear, but my brain is fried. I started with the chainlink root (I don't know about unlocking bootloader, like you ask) and I forgot to confirm it was rooted. Installed xposed. Somewhere along the lines I either lost root or was just never rooted, because it doesn't show the pound symbol in terminal, but then I flashed my backup which was after chainlink and before xposed, but I'm stuck in a bootloop on that backup. I tried installing this with TWRP but it just failed and said "error executing updater binary in zip." I thought maybe it was TWRP so now I'm on CWM and it does the same thing. I then tried this but when I do the bootloader upgrade it says I need to, it fails and says SW REV. CHECK FAIL. DEVICE:2, BINARY:1 in red. I don't know what's going on, but I hope I'm not bricked. I just got this yesterday lol any help would be appreciated. I can't find any answers. I really just want the stock 4.4.2 with root and maybe the Boeffla kernel. Please help! Thanks!
Edit: now I unplugged and it's saying "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again" and won't turn off. Queue freak out mode "
I rooted my device, everything was fine until then but i wanted a custom rom so i tried to install twrp via odin, this didn´t work and the phone would not boot (recovery error validating footer) so i downloaded the stock firmware in the forum, when i tried to flash it odin got stuck at "setup connection" for like 30 minutes so i restarted the phone and instead of going to the download screen it displayed "an error has ocurred while updating the software, use the emergency recovery function in smart switch"
Smart switch didn't work so i came back to odin, now when i try to flash the stock firmware it tells me "sw rev check fail bootloader device* binary 1" i can´t tell what binary the phone has because the notch is hiding it but i can tell that the problem is that i cant downgrade the bootloader, where can i get a newer firmware? or can i just force the downgrade somehow?
now i´m stuck with a phone that won´t boot :crying:

Hello Dear modders!
I Got a samsung s9 from my dad and i wanted to install twrp. So i did the usual (unlocked bootloader, turned on debugging yada yada.) and went into odin mode. I put in the TWRP path into the ap segment and i said: "Lets Go!". Aaand it showed an error "Only official Binaries are allowed to flash (RECOVERY)". I instantly googled what was it but only what i got was the error while booting. Booting worked for me normaly so i checked in dev options if i unlocked the bootloader but the option wasnt there (in ODIN MODE it was showing it was unlocked) so i panicked really bad and thought i make a post here!
So Here i am.
Please Help.
.
So phone was soft bricked.I couldn't get to the home.It was rebooting to odin mode(download mode) or bootlooping but i could not reboot phone to normal.So I decided to flash a custom rom in Odin.First I was getting fail beacuse of frp.And I also tried twrp recovery and it also failed.After trying download mode said "an error has occurred while updating device software" and i tried to fix this with SmartSwitch but that failed(when I was connecting my phone it said unsupported phone and i couldn't do anything).So I found unofficial variation which is FRP Hijacker.And it worked well.I could get back the normal downlad mode and also recovery mode.After this i tried again to flash rom.It was successfuly flashed.I thought it's done, but no.Phone was bootlooping again.I didn't know what to do.So I found on internet combination file for this phone and flashed it in odin.It failed after this i rebooted my phone and it showed again the "An error has occurred while updating device software".So I opened again FRP Hijacker and clicked to "SoftBrick fix" and after this my phone died.And now I can't turn on the phone,cant get to recovery or download Nothing!It also is not charging.
Could someone help me pls?I will be so thankful!!
