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 need to root a Note 3, SM-N9005 ATL Android 5.0 N9005XXUGBOL3. It is encrypted and would like to be able to recover the data that I have. Using the Smart Manager app was restarted and has not returned to start, when it start asking for the decryption key, restarts, lock screen appears and restarts again, staying at the Samsung logo, varying the tone of blue LED and vibrating as if it were to start and again restart.
When I start it in recovery mode I get the error "e:failed to mount /data (Invalid argument)".
I tried to root to see if I can make a backup of the partition /data but it is not possible, I tried flashing by Odin CF-Auto - Root, CWM Recovery, Philz_Touch and TWRP, but I always get error, can only Flash the official recovery and the phone still does not boot.
I have not activated developer mode and I don’t know if I could do it from the recovery or flashing an alternative firmware.
If I couldn’t root it, I have to find a data recovery company, I need to get messages from a Samsung SAT about another terminal that they are repairing, so I would have restored the factory settings to see if it works again.
Can anybody help me?
Thanks.
PD: Sorry for my English.
Hello guys,
I need extremely technical help as no longer know what to do.
I have a Galaxy S7 Edge device, which installed the rom BobCat and everything went well until then.
Later I decided to install another rom to test KingRom that left me unsatisfied, because I thought it had some bugs. Had the TWRP 3.0.0 recovery and decided to upgrade to 3.0.2, everything went well.
At one point I do not remember when or how if was when install back, downgrade to TWRP3.0.0, I do not remember if it was via Odin or TWRP, it happens that the installation stopped halfway. Then unplug the device, restarted in recovery mode and got the following message "E: falied to mount EFS (Invalid Argumen)", I could not restart the device (Boot Loop, and stucked at Samsung Logo) except in Recovery Mode, which also made to stay without IMEI number and Serial Number.
I googled until I came to this tutorial:
http://forum.xda-developers.com/s7-e...ssues-t3379516
I followed all the steps explained, I back up EFS_backup and RADIO_bakcup partitions.
Installed FACTORY BINARY G935, everything went well. After restarted, already had the correct IMEI number but still did not present the S / N.
After all that, i tried to install Stock Firmware via Odin, from here started the problems that could not solve.
In the first attempt Odin stucked in "System" (also used the PIT file with the same CSC ... .i do not know if I was right using PIT?). Restarted the device forcibly, entered the stock Recovery, did a complete wipe and always get this message "E: falied to mount System (Invalid argument), I returned to install Factory Binary, then reboot in Recovery and the same message no longer appeared.
Again I try to install the Stock Firmware and Odin always stucks in System, or NAND writing, or Partition, etc. I've tried various Stock Firmware, with and without PIT files, always without success.
Only Factory Binary that successfully installs. The TWRP via Odin also but when device restarts to enter Recovery Mode always get the message at the top of the display:
"Recovery image signature check Fail"
"Reboot to avoid Warranty bit set."
1. Does the partitions are in good shape? how can I check it?
2- I did good or bad using PIT file?
3- Does the problem is running Windows XP through a Virtual Machine?
4 What else can I do?
In all actions used and am using a Macbook 4.1, OsX Lion 10.7.5, Odin 3.11 Windows XP Professional 32bit through Oracle VM VirtualBox 3.4.38
Device:
Galaxy S7 Edge (SM-G935F) CSC = SWC SwissCom
1st Original Firmware: (I guess was 1?) G935FXXS1APG5_G935FVFG1APF3_SWC
Need help Please
Thank you so very much!
Update: [SOLVED]
Thanks GOD .. Kies Emergency Firmware Upgrade Solved it. Same Smart Switch Method.
Help Me please. I flashed TWRP to my SM-G935FD with odin preparing to root it.
But i found the internal storage is 0 bytes.
so i can't find zip file to flash supersu or mount storage to PC.
i found a solution, it was by changing file system and go back to original file system.
i tried this, i changed it. it typed Done. but nothing shows of back or home softkeys of TWRP.
So i restart my device to TWRP again but it freeze in splash screen.
I tried Smart Switch it give me message that it can't recognize my device.
Odin give me FAILED (DeviceInfo).
Any Solution? or My Device is dead now?
When using Samsung SmartSwitch it is normal that it says it does not recognize the device after you have tried to root it and failed.
You need to put the phone in download mode and use the "Emergency Software Recovery and initialization" in the Smartswitch software. You will be asked to input your model number and the serial number. It will then return it to stock.
You do so at your own peril.
[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?
My mobile is working fine until i reboot once. I got frp error on booting time. Then i got it is boot error. So, i search on somewhere and install BL file in mobile by odin. Now i'm getting the following in my boot logs the problem is same but here is not error showing (stuck at samsung galaxy j5 logo). So, i recovery logs at check boot menu.
E :failed to mount /system (Invalid arguments)
I have also tried to update through adb but it is disable in my mobile.
I have also tried to update through external storage but it is disable in my mobile.
I have also used https://forum.xda-developers.com/galaxy-j5/development/recovery-samsung-galaxy-j500f-t3416960 and getting error blocked by frp lock.
did you try to flash firmware with odin?

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.
