A bit of history:

I got this Samsung Galaxy S III from T-Mobile SGH-T999 Decided to to play with Cyanogenmod.

  • Rooted my S3 - success
  • Installed Cyanogenmod following instructions - success
  • Got notification that Cyanogenmod update available ( around 2/20/2014) - downloaded and installed the update which SOFT BRICKED my SGIII

Decided to go back to stock due to these update issues with Cyanogenmod


Used ODIN v.3.04 to flash a stock ROM for my phone that I got from:


file name: T999UVUEMJC_T999TMBEMJC_T999UVUEMJC_HOME.tar.md5

Successfully flashed it with ODIN

All went well except I cannot turn on WiFi.

When I click the WiFi button it turns dark green (apparently trying to turn on WiFi) and then turn back grey

Any help and suggestions would be highly appreciated.

    How about you try flashing the stock ROM AGAIN? – geffchang Feb 27 '14 at 9:44

    I hooe you've done a full wipe before flashing. Moving from one ROM to another w/o full wipe causes issues. – geffchang Feb 27 '14 at 9:45
  • Full wipe, reflash the ROM. Also have you flashed the correct Baseband for your device also? If this is a newer version of Android (4.3 - 4.4 particularly) chances are you need a newer modem (baseband). They are here: forum.xda-developers.com/showthread.php?t=1880987&page=1 and you can Odin flash them. I often say this, but CyanogenMod is quite buggy in the Nightlies and non stable candidates, expect issues like this to be honest. I'd try the baseband, or start at Stock all over again and reflash, try another ROM also to test. – RossC Feb 27 '14 at 12:45
  • @RossC thank you for your advice. I did not do any wipe. Two questions: 1. Can I do full wipe from CWM or there is a special procedure ? 2. I downloaded the modem zip file for my model. Since it is not a tar.md5 I should install it from my SD card using CWM ? – AstroSharp Feb 27 '14 at 16:10

    1 yes. 2 it depends on the model, as a rule use odin for your baseband! Flash on odin the tar file in phone – RossC Feb 27 '14 at 16:12
