I installed TWRP. When trying to install Magisk it "Failed to mount '/data' (Invalid argument)" and "Unable to mount storage". The same happend while trying to backup. As mentioned in some other threads (like here: https://www.youtube.com/watch?v=T-7neHzSIvc) I tried changing the File System to exFat. (And back to ext4 afterwards) I was stuck in Formatting... screen with "Formatting Data using mkexfatfs... Done." for like 2hrs or so. After that I got "E:recv error on uevent" multiple times.
After 8hrs of waiting, I rebooted. Now I just get to the TWRP starting Screen. Odin Mode is still working, so I tried flashing TWRP 3.1.1.0. Stuck in boot screen, too.
SOLUTION: I just flashed back Stock-Rom.

My S6310N refuses to complete boot up, after trying quite a few ROMs stays frozen during booting. Even giving me errors in the recovery, are the kind Unable to mount '/ data'.
This is the error log during wipes on TWRP recovery: i1352.photobucket.com/albums/q655/obiwan2208/zx.jpg
For the rest I can flash with Odin stockROMs and TWRP, but after the Samsung's animated logo leaving the SAMSUNG letters flashing and stay frozen there.
I tried to make wipes and although do something, continue without mount 'storage', '/data', etc.
Also with Odin I checked the option "Nand Erase All".
Has been corrupted the file system? Must to be formated somehow? Any fix will be welcome. ThnX
Fixed by myself
It's done
As I see the smartphone can't mount '/data' I played with TWRP recovery and I formated 'data' partition.
Then for be more sure and works I checked out making one wipe (before gave errors) and it's OK: any red text.
Right now I'm flashing stockROM, TWRP, SuperSU... :victory:
Seems that 'data' partition was kept corrupted despite had to flash stockROMs
Hey, so I somehow bricked my Galaxy S6 SM-G920F. I wanted to root it, but then I got stuck in download mode (at this point I think I made a huge mistake, because I haven't done backup of my device before). So I flashed G920FXXU5DQA7_G920FBTU5DQA2_BTU with odin. It works just fine for me without any errors to get at least in recovery mode, because anthores I tried don't work. But when I flash it, blue screen with "installing system update" and loading android logo show up for a few seconds and then immediately recovery mode comes back, where at the bottom I get these errors:
Suported API: 3
E: failed to mount /efs (Invalid argument)
E: failed to mount /efs (Invalid argument)
E: failed to mount /efs (Invalid argument)
dm-verity verification failed...
Tried to do emergency recovery with smart switch. It passes without any fails, but then I get stuck in recovery mode with same errors. When I try to reboot system, black screen shows up. Did I somehow lost my efs file? I'm not a pro at these situations, so I really need help.
Hello all. I have a oneplus one. My phone was turned on working fine as it was charging. Then out of nowhere it went into a bootloop. The system would not boot and just stayed on the cyanogenmod boot up screen. At the time I was on cm13. I can access fastboot and twrp. While in twrp the storage will not mount. I get numerous errors when trying to format, wipe etc.. What's also strange is that in some of the instances, I get errors but at the very top it says wipe or format was successful. Any help will be much appreciated. Thanks in advance.
The errors I get:
Failed to mount data(invalid argument)
Unable to mount storage
Unable to repair system

Hi mate
First some more info...
What firmware you had?
Was it working?
What firmware are you trying to flash?
What files did you use , odin settings?
Hey guy's,
I am having similar problems to OP. The "DM Verity error"
The other day my S8+ went into boot loop all of a sudden, I tried all the simple solutions, factory reset etc, nothing worked. The phone kept booting and wouldn't make it past the device model screen. I have tried multiple firmware for my region and have tried dropping down to Nougat.
At this point in time I am able to successfully flash with Odin, haven't had a failed flash yet. Once the flash completes, the device restarts, goes to device model screen and will either enter the "installing update" screen where the install will either crash straight away or at 25%(no more no less), then only sometimes will it take me to the recovery menu.
Down the bottom of the recovery menu is the "DM Verity error". I then proceed to wipe cache, factory reset then reboot device, only to be stuck in a boot loop or on the crashed install screen.
The device is still under warranty but due to dropping it (with glass prot and case on), a small mark has appeared on the LCD. I tried to return the phone to get the software issue fixed but will be charged $400 to replace the screen as Samsung will not send the phone back in an "un-warrantable" state.
I have been trying to solve this issue but i'm finally stumped.
Any help would be very much appreciated.
Thanks.

Hey all. First post and I need your help.
S8 randomly restarted and was stuck on the "SAMSUNG" logo screen. Restarted it and it said "applying update" but then "no command" screen with dead robot.
I've tried to factory reset it but "unable to mount drive" appears. I've tried reflashing with Odin. Seeing if I could boot with adb and wipe from there, nothing.
Corrupt drive pops up on occasion and it tries to wipe itself but this message comes up after it fails.
wiping data
formatting /data
E: /sbin/mke2fs_static failed with status 37
E: format _volume: failed to make ext4 on /dev/block/bootdevice/by-name/userdata
no such file or directory
Any help would be appreciated. I dont want to have to pay for a new one.
I was able to reload everything after a NAND erase
