Root [T-Mobile] Possible Brick - please help


Jun 20, 2012
T Mobile S4 was running cm10.1. Phone prompted me to install cm10.2. So I did. Phone was stuck in a boot loop. I went into recovery and wiped cache, dalvik, and then factory reset. Once phone reboot, 10.2 was installed and the boot loops stopped. While trying to install gapps, I accidentally selected install zip from sideload (instead of sd card). I selected go back and no my SD Card won't mount. Tried reformatting the SD Card and then unmount and mount in the phone (Settings > Storage) but nothing is working. Please advise. Thank you ahead of time.
Booting into download mode is when you turn the phone completely off. Press volume down and power button. The phone enters download mode, from there you want to press volume up button and confirm that you want to enter download mode.

When you enter in download mode - on the upper left you will see writing - if you have not updated to 4.3 with the official over the air update or using Samsung Kies it should say on the second to last line ---- 0x30.

This is the old system and it means you do not have knox. If it says something like 0x0 or 0x1 than there is trouble.

Assuming you are on the old system which I am in and you are able to get to download mode.

Here is a guide of how to unbrick the phone

Make sure you have ODIN I personally recommend the new version of odin which can be located http://androidforums.com/t-mobile-g...w-install-twrp-recovery-root-install-rom.html - other than that the guy is pretty detailed in how he is explaining it.
