After reading around on the internet I saw it maybe a firmware issue. So after doing some research I decide flashing it maybe the best solution to the the problem. After spending like a couple of hours ensuring I got the correct version of the firmware I got everything ready but when I put it in download mode I realized I maybe the wrong one.
(From Phone Info Samsung app)
Sticker under battery says its the I9500...
In download mode I notice that is said that the model of the phone was SGH-I337 the AT&T I9505. Which confused me and made me want to check which firmware to get. The 3rd image doesn't really make sense based on what I have read along with fact that the first image calls the phone the i9500 but the 5th image shows the i9505 qualcomm processor. Also on the 1st image what is "jflteatt" under the device type?
I'm not sure what to do now, any help would be most appreciated.
