[Galaxy S 4 Active Q&A, Help & Troubleshooting] HC1Gunner:
SGH-I537 AT&T

1. Phone is never seen by or connects to Kies, just stays at Connecting. USB drivers are installed, and when connected to PC you get device connection tone, but phone is not seen in My Computer like normal.

When I enter the Model # SGH-I537 and the SN#, it comes back with...Please check the model name and enter it. Or it connects and message comes back from Samsung saying something like it can't verify the phone. For some stupid reason I can't find the latest official firmware for my phone 4.4.2, all I can find is 4.2.2.

Someone told me if you flash using Odin that you need to flash with the same firmware that is currently on your phone. I also hate to use Odin as I've heard of so many people bricking their phone with Odin. I'm not sure what's available for the I537, but once when I bricked my S2, I was able to connect a USB jig that shorted a couple of the pins, and this allowed me to boot into recovery. I wish I had something this simple of my S4 Active.

I'm in a bad way, I sold this phone, so I went into recovery to do wipe and reset the phone to factory, wipe was successful, but when rebooted it would only boot to Download mode. So then I tried to use Kies, and with Kies I never actually got into recovery, then the next time I rebooted, it went the Firmware upgrade encountered an issue for Kies, and is currently stuck there. I listed the phone online for sale and was purchased overnight. Now I have a phone that is worthless in its current state. Phone was only rooted, its never had anything else on it but stock firmware. I rooted it to use battery savers and get rid of some of the bloat.

I at updated it OTA to 4.4.2, and then rooted with towel. I tried to used Odin to push 4.3 I got off XDA official firmware, but that just failed. Anyone have an bright ideas? Help Please ! ! !
