I was on Baseband MF3 on Firmware 4.2.2 and rooted with Geohot's activeroot.apk, I wanted to upgrade to KitKat but I read I have to update to 4.3. I only renamed the Knoxfiles and the wcss updater odex and apk's and renamed them back to their original names. I fully unrooted the phone and did a factory restore. I tried downloading the 4.3 cfg file and putting it on the sd card and installing in recovery mode. I also tried flashing it wish Odin. Odin (3.07) always failed so I tried renaming the .cfg to update.zip it would fail the verification so I read deeper into the thread you can use ada and update it that way. I tried that and it failed both the 685MB file and the 721MB file. Then after browsing this section it said that since your phone has a locked bootloader a one click solution may help. I tried that it got a little further then it failed. So now I cannot get to emergency recovery and it says to connect to skies. I tried the 2.6 Kies and the 3.0 Kies. But on 4.2.2 its not recognized by Kies and I am at the emergency firmware screen. I can still access the Odin downloader though. I took it to Best Buy but their Samsung rep wen't home for the night, then I tried AT&T and they can't help. Any assistance would be greatly appreciated. Oh I also had safestrap installed but I removed it. However I did make a backup with Safestrap and it's on my ext SD card which has been removed from the phone.
