Hello,
Originally, my S3 didn't have the software update function when first used. This was when Jelly Bean was first being rolled out. I managed to put an unbranded version on my phone but it didn't seemed to like it. I couldn't remember the exact version I originally had but I found one online that seemed to be the same as my original, except it occasionally said T-Mobile UK as network.
I had tried to unlock the network of my phone using the service menu, but my service menu was different from all the others I seen online. I didn't have the UTMS option and can't seem to find why.
I am currently looking for the original firmware, if I can even find it if possible. I can't check the service menu anymore since I've updated to 4.3 so cannot see if it has changed
Thanks
