First Id like to say I'm new to all this stuff, rooting, flashing etc... So I don't know all the terms and such.
So I rooted my Galaxy s4 (sgh-1337m) and all was well, I tried to get a program called xmodgames running on my enforcing phone following some steps I found on YouTube. I had to make the xmodgames app a system app so I did that then I cleared my dalvik data as it was one of the steps, it cleared about 12 files then about 1 minute after doing that I got a error telling me a system file was not responding and I rebooted my phone, it wouldn't boot past the Samsung launch screen. So I had to hunt around for some stock firmware, I did that found what I believed to be my stock firmware, put it on and all seemed well, except my WiFi just wouldn't turn on. I tried clearing my data, reformatting it to factory, Download kies and updated it through that and now my phone is a mess, its slow, WiFi still doesn't work, I cant see the task bar at the top where it shows battery status and WiFi status and it locks up on me. At this point I'm downloading a more exact firmware meant for a koodo s4 sgh 1337m which is what I have. I'm downloading the oldest one from 2 years ago as its about when I bought this phone. And I'm going to see if that helps, I also read there are WiFi fixes and modem fixes but I have no idea where to start with those. Also its only my WiFi that doesn't work, Bluetooth, data, phone calls All work.
