hey guys! im pretty good with samsung phones i had the sprint gs3 and gs4 in the past.. well i have a friend that has the verizon gs3.. i rooted it a while back flashed a rom and he has been running it for like 6 momths or more with no problems.. its a 4.2.2 rom.. so how do i go about updating to the new base?? 4.3?? can someone link me to the process.. is there like a firmware/modem i need to flash.. then flash a 4.3 rom>? yes he has twrp recovery and a custom rom now.. can i just flash the new modem the flash a new 4.3 rom? or do i need to do something else..?
Well, if he doesn't have issue with signal, then you shouldn't have to flash the new ML1 modem. If you want to flash it anyway then here http://forum.xda-developers.com/show....php?t=1788313
There are a bunch of custom rom, either TouchWiz custom rom or just custom rom you can choose from here http://forum.xda-developers.com/gala...on/development
If you want to stay away from bugs, pick the one that close to stock rom as much as possible.
