The main error I get is this error and the wipe fails:
E:Unable to mount '/system'
E:Unable to mount '/cache'
E:Unable to mount '/modem'
So I tried to mount them manually, but it wont let me select those partitions.
I thought it was TWRP, but CWM 22.214.171.124 does the same thing because of the mount problem. I've already unbricked/went back to stock 3 times using RSD Lite 6.1.5. These errors are preventing me from restoring both backups I have from internal and external SDs. I've also tried go through FASTBOOT by using this command:
-fastboot erase system
But then it tells "permission denied". I'm using Windows 8.1 and changed the permissions in my fastboot folder. So now I only have access to fastboot or recovery.
Another thing i've noticed is that sometimes TWRP would crash and restart in the middle of a restore or wipe. I reverted to 126.96.36.199, this would still happen.
I've searched and searched but can't find anything to help with my issue. Like i've said before, I already returned it to stock rom 4.1.2 three times. What else can I do to properly wipe so I can flash a rom without any problems?
For those who might have the same problem, i'm leaving the post as is. Here's what I did:
-Went into FASTBOOT and loaded an older version of TWRP. In this case, I flashed version 188.8.131.52(in other cases, I've had to use 184.108.40.206)
-Did a Wipe/Factory Reset(Do it 3 times to be safe)
-Reboot to FASTBOOT and flash back to the newest version of TWRP(220.127.116.11)
-Flash your ROM and make sure to Flash the correct compatible gapps
-Voila, everything should be good to go
