so i had android 4.3 stock rom but then switched to cyanogemod 10.2.. today i decided i wanted to go back to stock rom so i tried using odin 3.07 and flashing I747UCALG1_I747ATTALG1_I747UCALG1_HOME.tar.md5 (i cant find 4.3 firmware anywhere). i go into download mode, put that file in PDA, and odin tells me:
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> I747UCALG1_I747ATTALG1_I747UCALG1_HOME.tar.md5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..
<ID:0/005> Odin v.3 engine (ID:5)..
<ID:0/005> File analysis..
<ID:0/005> Get PIT for mapping..
<ID:0/005> Firmware update start..
<ID:0/005> NAND Write Start!!
<ID:0/005> FAIL! (Auth)
<OSM> All threads completed. (succeed 0 / failed 1)
and on my phone is says SV REV Check Fail : Fused 2 > Binary 0
i was trying to find stuff out online and they said something about a bootloader and i have no clue what that means. also, cyanogenmod is no longer even going to the home screen so my phone is not functioning at all. and since it isnt loading, my computer isnt detecting a device so i cant add any files to my phone.
can someone please help me? using english please, not computer hacker language. im not that advanced in this kind of stuff.
