I bought a AT&T LG G2 on swappa which I am using on Straight Talk and all is well except a few glitches. I haven't used a ROM'ed phone in a while since my last phone was a locked RAZR HD so forgive me if I am a bit rusty. The previous owner had installed the 1plus1 v 1.0 build with the 3.4.0-CM+ Kernel. Every hour or so the screen stops responding and I have to restart the phone which can be frustrating since my job requires frequent calls.
I am looking to switch to the Cloudy G3 ROM (or another one you guys recommend that is the least buggy). Do I have to do anything besides a full wipe and install the Kitkat baseband then install the Cloudy zip? I have done a nandroid backup (or whatever the equivalent is called on this phone) in case something goes wrong. Also, what is the best way to backup my call logs when I switch ROMs? I have Titanium but not sure which thing to restore.
