Phone stuck on T-mobile screen

[Rgomez90]

Hello everyone
I think i've seen around the same post but i decided to post a new one and explain my problem exactly.
I've a SGH-T999L T-Mobile S3 version.
Same issue, i did factory reset in order to free memory, my phone was updated to 4.3 version but after the reset it keeps frozen at T-mobile start screen, i've tried many possible solutions to fix it but any of them has worked. ive tried installing am official firmware provided by sammobile via ODIN, i've tried using the update and initializing option in KIES tools menu, both of them seems to have worked since they install the firmware but when the phone reboots, it's still frozen in the T-mobile screen, by the way i've noticed that a command line appears in recovery mode in red, it says:
E:failed to mount/data (invalid argument)
cant mount '/data'(invalid argument)
E:failed to mount/data/(invalid argument)
E:Can't mount/data/log/recovery_log.txt

Please if someone had the some problem and found the way to solve it, please let me know cause i cant apply to warranty :'(
