Hi, I have a Samsung Note 2 running Android 4.3, this is a mexican phone that I took to a shop to unlock it as we moved to USA and wanted to keep using same phone with different carrier, as I'm not an android tech.
Since the unlock, internet network is not working properly, in US I bought a Tmobile sim card, everything works fine except network, it only works on H+ or E networks, I took it to a Tmobile shop and they told me that phone is not running on the correct version of OS, that I need to update it.
When I attempt to run software update it sends a message saying that the device was modified and there are no software update availables.
It seems that unlock was made thru a software patch and installing an application called SuperSU.
Phone doesn't allow me to desinstall the application.
Is there a way I can desinstall it? Or reinstalling all OS? I'm tired of having bad performance in network...
Please help me, if you know any other way to solve it, please let me know.
