The I googled it and found that my phone is softbricked and I have to reflash the stock rom. Then i downloaded the stock roms I337UCUAMDB and I337UCUAMDL .
But while flashing them I get this
<ID:0/004> Odin v.3 engine (ID:4)..
<ID:0/004> File analysis..
<ID:0/004> Get PIT for mapping..
<ID:0/004> Firmware update start..
<ID:0/004> NAND Write Start!!
<ID:0/004> FAIL! (Auth)
<OSM> All threads completed. (succeed 0 / failed 1)
The phone displays this:
Start [224, 1440]
SV REV. CHECK FAIL : FUSED : 2, BINARY : 1
I get this message from both the above roms.
