You need to FORMAT DATA in TWRP before
you flash supersu.
Select WIPE in twrp then select FORMAT DATA
and follow the promps.
Please note:
Formatting data in twrp will erase your internal memory
so if you have anything important back it up first.
Good luck, have a great day!

Hi, I need your help guys, this is the problem:
I have a G9287, in last G9287ZHU2BPE1 6.0.1, stock kernel, rooted with flashed BETA-SuperSU-v2.74 and with twrp-3.0.2-0-zenltezt.
Suddenly it started to behave weird after installing some quick boot programs from play store. So I tried to recover it with a TWRP nandroid backup. And it failed, it said after that:
EXTRACTTARFORK () Process ended with ERROR: 255
I tried doing twice with same results.
So I decided to install original firmware again with Odin. All the Odin process went OK, so it rebooted and started to "installing system update" it went for a while and count some percentage up to 32% and then some more "installing system update" and after a while it went twice to Samsung start screen, it did this bootloop twice and the it went to Samsung Recovery with this legend:
E: failed to mount /preload (Invalid argument)
Supported API: 3
I tried again with Odin and also with Smart Switch with same results.
I tried Samsung Recovery wipe data.
I also tried TWRP wipe, first full "advanced wipe" and after same results, "format data"
Then tried Odin again and same resuts. Incomplete "installing system update" with Odin and Smart Switch.
So I went to download mode and with Odin flashed twrp-3.0.2-0-zenltezt with success
and then flashed Audax_Plus_M_v6.0 with complete success again.The ROM opens perfectly as expected. But only shows one not working SIM signal.
My problem is that I can not stay in this custom ROM since it doesn't support dual sim as my version is. Also there is no custom ROM that I know for G9287 version.
So, because of this, I then went again to Smart Switch to try to intall last firmware version. And get same results, an incomplete system update with same legend in Samsung Recovery.
I have googled all the legends I have gotten, with no conclusive results.
So, I am asking for your advice. Thanks in advance.
Anyone with more knowledge and experience than me, I am a noob, I have keept trying , with same negative results. Audax installs and works perfectlly, samsung firmware still the same, Odin flashes perfectly and ends succesfully and then starts "installing system update" makes a count to 32%, says "erasing" and after some second with system update ,again, shows the dead android and an exclamation and then goes to samsung recovery showing:
Supported API: 3
# MANUAL MODE #
-- Appliying Multi-CSC...
Applied the CSC-code : BRI
Successfully applied multi-CSC.
And if I reboots same results again and again.
I'm now with TWRP 3.0.2-2, I have wiped and full format all partitions.

Hey, this is ''no free storage in your phone'' failure I get this error many times while restoring, make sure you have more free space than back up size. I couldnt read your post completely, just in case if you restore old LP data etc, it may cause some issues.
Also have faced E: un/mount th?ng before, wipe all excluding internal» helped me in this case. Good luck.
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

Hello, Is there any update about how to fix?
Any way to fool your kernel/recovery into thinking dm-verity is just fine?
Samsung s7 says dm-verify verification failed after been reset
Hi, I think I f***** up badly...
I wanted to root my S7 Edge SM-G935F running android 7.0 so I enabled USB debugging and OEM unlock.
I used Odin to flash a CF auto-root I found for the 935F for android 7 and the site just said I had to install SuperSU after that but it was just boot looping.
After that I installed TWRP for my phone and installed the zip with Superuser. I kept receiving the error "failed to mount /data (invalid argument)".
I googled it and found a video that said I had to change my system "file system" from EXT4 to FAT. It was stuck so I rebooted the phone...
Now I can't load TWRP (it's stuck at the loading screen) to do a factory reset and when I do a normal boot it doens't go further than the S7 Edge screen, it doesn't go to the flashing SAMSUNG screen.
Now when I choose to reboot in Odin mode it says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I tried to do that but it says "unsupported device" and it doesn't see my phone in the Emergency Software Recovery tab.
I could have done a factory reset before but it's not the first time I root a phone and I never had a problem so I didn't back anything up but I have some very important pictures on my phone for school.
I enabled adoptable storage so I couldn't just take out the 128gb Samsung Pro + micro sd and copy the pictures on my pc.
Can somebody please tell me how to factory reset my S7 Edge even if I lose all my data. Sorry for my English it's my third language.
Thanks in advance
If I can remember correctly the "An error has occurred while updating th......." screen is actually the same as download/odin mode, so you can odin flash back stock rom.
Your data has probably already been lost during file system changing which automatically format /data.
Also I have never seen any phone run on FAT file system. S7 only support EXT4 and F2FS(required custom rom and kernel). So be careful next time.
AFAIK, there's currently no root available on stock nougat touchwiz rom unless you use modified kernel&rom.
For TWRP to be able to read /data.
/Data need to be FORMAT in TWRP once to remove encryption, so that TWRP can read it.

Hello,
I made a mistake and flash a bad kernell to my Note 3. After that it boots only to a black screen and after that it reboot to system recovery. Reboot to bootlader doesn"t work.
When I tried to load new official rom using ADB or "update from external storage", it says "Footer is wrong, signature verification failed".
Its Android 5.0 (see screenshot) and the "bad" kernel is N9005XXUEND3. I cant connect ODIN or KIES. Is there any way to repair it? Thanks for any help.
You cannot update from Storage its the wrong format .
Samsung updates KIES or ODIN .
But It's not possible to connect ODIN or Kies and update from external storage is in the menu of my recovery. There is also "update using ADB". But there is a same problem with footer and verification....
Take it to a repair shop .
[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?
