I have been rooting and installing roms for at least 8 years. For some reason I am just having all sorts of trouble. For one thing I have NEVER messed with flashing modems, or kernels. So I have had excellent success with CleanRom AT&T adition for note 2. It just works, problem is, it is old OS version.
Basically, what I am asking here is, how can I get the same modem (or whatever) that is in cleanRom? The signal is great and the data is great. This and many other Roms I have installed do not have strong signal.
How do I find a proper modem for this phone? I have the AT&T SGH-i317, but that is all I know. I have tried to read about this stuff, but it is VERY hard to decipher what to do with all the updates, and what works with what rom, or android version.
Can someone help me find the proper modem? Please do not just send me to a FAQ, I have tried and I need specific help.
