That said, here's the deal. I've got an i777, which I have unlocked and am currently using on T-Mobile. I've flashed the stable CM 10.1.3 (Android 4.2.2). Its baseband is UCLE5. It's running well. I have few complaints, except for occasional low signal.
I've already seen this thread, with the different modems available: http://forum.xda-developers.com/show....php?t=1336958
I lost the link, but I also found a thread, possibly on another forum, where a T-Mobile user reported better performance with baseband UCMD8. I'd like to try it. I think I can manage flashing it on my own via CWM.
However, I've read in a bunch of places that it's also important to have a RIL matching the baseband version. I found a thread that gives a terminal emulator command to find your current RIL version (getprop "gsm.version.ril-impl"), and mine is "Samsung RIL(IPC) v2.0", which is apparently from Gingerbread.
So, my question is this: Should I also change my RIL? If so, 1) where would I get the appropriate RIL for the i777 with CM10.1.3, and 2) how would I install it, preferably without performing another wipe, reset and ROM installation?
Thanks in advance for your help!
