Galaxy S3 Soft Brick. Please help
Phone model: Galaxy s3 T999L TMobile USA
I have a sim card in it where everything is stored, no micro SD card
I rooted my phone with CWM recovery Mod v184.108.40.206 a while ago. I finally decided to flash a custom ROM. The problem is I wasn't careful and tried to install the wrong version. It didn't work and all I can do now is boot into CWM recovery. I have no backup of the system image cause I did something wrong when I was messing around in CWM recovery. So I can only boot to recovery or put it in download mode.
Id like to unroot it and get it back to factory condition, or at least flash a custom rom from the CWM recovery. I downloaded and tried using every version of Odin to flash a stock rom. I get a failed everytime I try. Here are the messages I get from Odin:
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> T999UVDMD5_T999TMBDMD5_T999UVDMD5_HOME.tar.md5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..

any help would be greatly appreciated.
