Okay, I need help and I feel dumb..
I rooted my s4 just to try it and I'm stuck trying to get it to go back to stock.
I have a note 3 now and I've got everything going well with that but the s4 (I have the I337).
I have it rooted and the phone will start and is a perfectly functional android phone, but whenever I try to get it into recovery mode I can only get it to go to download mode. Odin flashes to stock fail with this:
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> I337UCUAMDB_I337ATTAMDB_I337UCUAMDB_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)
the stock flash was linked to by others I found on XDA.
Also, details about the phone:
Jelly Bean 4.2.2
Thanks for any and all help!
