dm-verity verification failed recovery - Sprint Samsung Galaxy S7 Questions & Answers

If i modify the system partition, the recovery greets me with "dm-verity verification failed".
I do *not* get the message about the DRK being invalid. My phone works fine.
Is there a way to remove this cosmetic error?

I suppose that will work but i want my system partition modified/themed the way it is
I've heard it has something to do with the efs partition inside /efs/prov_data/dmvt or /efs/prov_data/dev_root
Maybe i can recalculate the hash value for the system partition and inject it somewhere?

My DRK is fine. just wish to remove recovery error.

i'm on stock recovery and my unit will always boot because I have the G930P eng kernel with dm-verity disabled. Stock recovery still thinks dm-verity is enabled because it just says "dm-verity verification failed" which is normal when you modify the system partition. I'm only trying to figure out how to remove the dm-verity verification failed error.

i can do such repair remotely

Go to recovery mode. factory reset. should boot now.

Hello, Is there any update about how to fix?

Any way to fool your kernel/recovery into thinking dm-verity is just fine?

dm-verity error...
Can anyone explain why it shows dm-verity error...
(and before anyone asks if i know what dm-verity is Yes i know what it is it's the function of the kernel that prevents unauthorized flashing unless the packaged is signed by the factory)

[HELP] Trying to transfer my rig, now I get a "Verification Failed" message on boot!

[HELP] Trying to transfer my rig, now I get a "Verification Failed" message on boot!
This is urgent! Please help1
I tried to transfer my phone's rig to another of the same phone. A guide here said to use TWRP's backup feature. I failed at doing the Odin flash the first couple times and accidentally booted into the system. I got a "Verification Failed" screen, with the only options being factory reset, and power off/restart. I figured this would go away once I flashed TWRP right, so I did, did that backup, but I noticed the backup was only ~4GB. I tried to mount the Data partition, but it reports 0B and won't mount. Every time I boot I get the same screen. I don't know what to do and I have no phone... and I need my data.. Please help!!! EDIT I also can't access TWRP anymore, and the normal recovery says "successfully verify for dmverity hash tree"
SM-G935W8
EDIT EDIT: I managed to boot using the standard recovery's reboot option... But I don't want this to happen again. Is there an easy way?

After flashing stock with Odin, enter in Settings, Developers Settings and activate OEM unlock and debugging, this will prevent the FRP lock, then you can repeat process to flash TWRP and root phone if you want and so...you will be fine.
Thanks for your time actually at that time firmware unavilable from official site so i was trying to make it from unofficial website but now problem is resolved. Again thankyou for support.

soft bricked my G928F

It's a long story but I soft bricked my G928F.
I bought it off Gumtree in the U.K and it had an frp lock on it, the seller stated that she had wiped it off so would not take it back. I had a read around and it seemed that Wondershare Dr. Fone would take off the frp lock........it didn't, rather it messed up the stock recovery. When attempting to enter recovery I get the following message and am stuck in a bootloop:
No Support SINGLE - SKU
Supported API: 3
dm-verity error
failed code: 0x02
E: failed to mount /cache (invalid argument)
While Odin will recognise the phone Smart Switch will not so I am unable to use the emergency recovery procedure.
I have read similar posts where it implies Smart Switch is the last resort but in my case that doesn't seem to be an option
Can anyone suggest a way to recover the phone or do I throw it in the bin? Any help appreciated

Flash this using odin :
https://drive.google.com/uc?id=1tg9hJOCquyfuyROYtgpxyVKNbuidzdL8&export=download
Then, you will be able to flash latest version normaly, and also your will remove frp lock.
Thanks for that, I will flash it when I get home and report back.
Didn't work for me, the combination file gave an 'md5 error! Binary is invalid' message when loading into Odin, while renaming to .tar the flash failed.
firmware update start
Single download
sboot bin
param.bin
FAIL
Thanks for your suggestion though.
I tried installing firmware G928FXXS5CRH1 (VOD) but it failed at hidden system image, I removed that file and created a .tar which flashed successfully but the phone rebooted
to recovery initially but still showed a dm-verity error. I deleted the cache and then factory reset which appeared to also complete successfully but the phone would not boot up.
I then tried flashing the hidden sys image on its own but that failed and the phone went to the Smart Switch error recovery page, Smart Switch will not recognise the phone so will not allow access to the emergency recovery facility.
Still trying though if anyone has any idea's.
Hi there,
Im in the same boat. It had the verity error too.
BUT:
For me it worked to flash the 4-part firmware of the G928FXXS5CRH1 via Odin then.
The device boots again, without the verity error
It had Android 5.1 before, when I could flash the COMBINATION ROM and use it just fine.
(but it was a Android 7 combination ROM) :/
After flashing Android 7 debranded (G928FXXS5CRH1) in 4-parts (BL, AP, CC and CSC file) the FRP lock is still there of course,
but the phone is booting again without the verity error.
COMBINATION ROM will no longer let me flash it, though.

The download I did via the tool "samfirm" use chk32 and decrypt on downloading !
"SM-G928F_1_20180828170540_5avji4munw_fac"
Thanks for the reply, I fixed it myself in the end. I spent 2 days over Xmas until I eventually tried the solution that you have suggested. I eventually found a 4 part software. AS to the FRP lock, be it good luck or persistence, I managed to get rid of that as well using Samsung FRP Tool.

Hell Friend, Not sure If you could get this message, If yes, Kindly help me., I am facing the same issue with my Samsung Galaxy Note 5 (N920G/I) but could not find 4 parts FRP unlock firmware. Do let me know If anyone finds one.
Thanks!

[Hard-breaked] S7 Edge SM-G9350 (G9350ZH Hong-Kong) Only download mode accessible

Hi everyone! Help! Need help! As titled, i have almost tried everything, frp lock is enabled i can't acces to recovery menu and i'm unable to flash TWRP recovery or boot into normal recovery, frp lock blocked everything, i can just access to download mode
Please, I need some help with my SM-G9350 Hong-Kong Galaxy S7 edge on Binary 4
I got custom binary TWRP recovery/boot blocked by frp lock when the device was working fine running custom rom, and then I flashed stock firmware via Odin and all was just fine and Odin succeed pass, but when installing system updates in recovery it was up to 32% then erasing and then it should boot up system, but it didn't it keeps rebooting to recovery with no options at all, just showing the android guy with no command below and then when I hard it to enter in recovery menu it shows a black screen with some lines that says couldn't open recovery cause unknown and no such file directory, and device is busy, and keep doing the same thing, I did same and flashed again with latest firmware but same thing happened, and then I tried to flash TWRP in order to flash a custom rom to boot up system, but Odin fails and says in download mode custom binary recovery blocked by frp lock, known that my device's bootloader is already unlocked and I flashed before this a whole of stuff, now, I can just access to download mode, otherwise I can't do anything else even no adb , there is no a combination file for the Hong-Kong variant G9350ZH, there is only for the Open-China variant G9350ZC which is not combatible with the device, even there are no adb enabled files, if someone has a solution for this, please kindly take care of this problem?

I'm having the same and exact problem as in this video with same brand device S7e https://youtu.be/l8-ccufk4Q0 the man could save the device by installing TWRP because frp was off. I can't do the same because I got frp on
I used to play with a whole Frp Remover Tools but nothing helped or worked, and also tried some cracked boxes but unfortunately they seem just like interfaces and didn't work as well
If I ended with frp lock turned successfully off then everything will be easy, installing TWRP then flashing through it no_verity_encryption will solve the issue and the device will boot the system successfully, I need to turn it off, if anyone has a solution please help!

This isn't good.... Unfortunately I can't help with this matter. I bricked my s7 and ended up exactly like this. I have not been able to recover it. So I gave up. Sorry to be the bearer of bad news.
What happens when you Odin your full firmware package?

Odin success passed the firmware's packages without problems, and it is the right one @klabit87, actually, there is a chance to recover the phone, I have found a video on YouTube having the same and exact problem as me with same brand device S7e, the man could save the device by installing TWRP because frp was off, I can't do the same because I got frp on https://youtu.be/l8-ccufk4Q0

I wonder if you could use a custom kernel with dm-verity removed altogether. You could Odin it. No need for twrp. What firmware version is currently installed? I will compile it for you if you want to try it. Maybe try verity will get you to a point where you could remove frp while booted. Is your bootloader still unlocked? As in OEM unlock I mean.

When tried to flash TWRP, it says custom binary recovery block by frp lock
And when tried to flash a custom boot that I took from a custom ROM and I Tared it, it says custom binary boot blocked by frp lock, I don't know if frp is related to OEM unlock or not and I don't know why it failed to Odin the boot that I took, the current firmware is CSC1 ..link for appropriated boot.img https://desktop.firmware.mobi/device:454/firmware:19931 if the device will read it as a custom one I don't think it will bypass it so, I would not disturb u if actually the phone will refuse it
But if crom service still off that means the bootloader is unlocked, once running for the first time on the device no need to use it anymore and the bootloader will be unlocked, but I don't know if OEM is enabled and it says in download mode secure download enabled

Ah ok. You're right it won't flash then. Sounding like a qcom CDMA tool might help. I've seen a couple that allow you to remove frp but I believe it requires entering qshusb mode. But it seems like options just get more and more slim now

Yes, playing around a right tool can remove it, searching and testing ..
Edit: @klabit87, all the tools failed
I have same model and same problem. Did you find any solution?
hi, do you have any update? I have the same problem and the same model too
Do anyone still need help in fixing this issue?
I would like you to join me in this experiment to fix your device.
