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
Friend give me his n8000 to try back it in life
it was on unknown firm, was not possibile to boot
I wiped cashe and data from stock recovery and odin installed new 4.4.2
all normal. But it again can not boot. It stuck few minutes on logo and then say go automatically in stock recovery.
There is written that E efs is invalid, something like this...
eny hope?
thanks
Restore your backed up EFS folder .
Fixed, although no mine backup. According to great manual, took efs from i9300, pit for n8000 and stock rom. Works!!!
I tried to upgrade to from Magisk V6 to V8 it messed up my phone so I restored a backup and all was fine, so I tried installing V8 a different way still failed, so restored backup again but this time I am getting errors that the system cant be mounted. I have tried repairing the system in advanced whipe but that failed so I chose change file system option and changed it to ext4 which it already was then restored backup and it lets me mount the system. But as soon as i restart my phone it just sits on the first Samgung logo screen, and does nothing and when i boot back into TWRP it is back to not mounting system.
What can I do to fix this? I need it done bercause I need my phone for work in the morning.
is left in the logo and when I enter the data recovery failed to mount the efs (argument invalid) but I am not used to flash any rom some help from an expert?
My s7 automatically boots up to TWRP
So I had a problem that I couldn't mount /data they said I should change the file system so I did but now phone won't boot and TWRP is stuck at the start logo my question is how do I change it back to ext4 without TWRP?
