Long story short - i tried doing a manual kitkat update and I am stuck at the screen shown in the attachment. As in the attachment, I am able to get to the DOWNLOAD MODE screen by pressing Volume-down+Home+ Power. My question how do i flash Jelly Bean or Kit Kat on this phone - I just want to get back to a working phone. Here are things I have tried: I tried downloading a ROM from XDA Developers for my phone (I am not yet allowed to post links here yet), and using Odin (pressed on PDA button and selected image to flash) and I get an error ... the screenshot for the error is also attached. History - This Samsung Galaxy S3 has an AT&T Jellybean 4.3 image but the phone is unlocked from the initial carrier (AT&T) and being used with T-Mobile now. z I sincerely appreciate any help here - this is my only phone and totally unusable right now. If this is not the right forum, please please redirect me to somewhere where I could get some help.
