I wanted to try a new modem but now I have no IMEI, tried restoring a nand backup with no change, tried flashing another rom with no change, I also tried flashing a root99 stock rom with ODIN and it says <ID:0/003> FAIL! (Auth) and in download mode it says SW REV CHECK FAIL : Fused 1 > Binary 0 and tried a couple different modems. How can I get my IMEI back?
