[Q] [q] help!!!! IMEI and BaseBand unknown after custom ROM flash
I am new here and wish to get help from XDA.
I just got a unlocked Samsung Galaxy S3 (SGH-I747) and inserted my Rogers sim card. The phone came with 4.1.1 and everything was good and I root it. Then I found that I have 4.3 update. I updated to 4.3 (I747UCUEMJB) via OTA and root it again by CF_auto_root. The only issue was the phone always boot up and show " Unfortunately,SuperSU has stopped". However, I did get the root after reinstall supersu.apk. So far so good till last night.
Last night I tried a custom ROM and flash it via ODIN. I got failed and I got the following from ODIN
<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)
and the following error from the phone.
SW REV CHECK FAIL: Fused 2 > Binary 0
After I boot the phone up, I found that the phone lost IMEI and baseband (should be I747UCUEMJB). The Build version changed from JSS15J.I747UCUEMJB to JSS15J.I747UCUEMJ2. Now I could not go to either Rogers network or Wifi.
What is the solution for this? ( I do not have efs backup but I write down some information such as IMEI)
I am thinking to flash stock AT&T 4.3 I747UCUEMJB might be the best solution, but I could not find it?
I have downloaded set of Rogers 4.3 (I747MVLUEMK5), may I flash them in to build a pure Rogers S3?
