[Q] HOw to revert back from MK2 (ATT SGS4 i337) to MDB or MDL topic

HI there,

DOes anyone have a solution for us stuck on MK2?

I have the following problems:

I bought this i337 second hand, and it came with UCUAMK2 firmware.

I rooted it with SAFEROOT (saferoot.zip). That worked fine.
But I cant install LOKI, to get the ClockWorkMod, so I can't install Custom ROMs.

Because when I type in the commands in Android Terminal, to flash loki's CWM recovery, it says :

[+] loki_flash v1.1
[-] Loki aboot version does not match device.

SO i figure, I have to revert back to MDB or MDL firmware.

BUT when I open ODIN, and try to flash the official firmware:

1. I337UCUAMDB_I337ATTAMDB_I337UCUAMDB_HOME.tar.md5

it FAILS in ODIN, so I (try) to flash this:

2.I337UCUAMDL_I337ATTAMDL_I337UCUAMDL_HOME.tar.md5

but that FAILS also!!!!!!!


SO should I install SAFESTRAP?
Some ppl complain, that screws things up, and end up in bootloop, and can't remove this SAFESTRAP...so i dunno if

i should install it.

Does flashing via/using ODIN FAIL==> because my bootloader is LOCKED?

Can you tell me how to Unlock my bootloader????


I need to go back to MDB or MDL, because otherwise I can't unlock the carrier restriction, since I'm on Vodafone,

and not on AT&T!

Plus, I was always installing custom Roms on my S2, S3, and all my other android devices since 2009....sorry to see

that the S4 is

such a headache....

Can you help me out please, seeing how good aof a DEV you are....?

Please and thank you
