I'm nervous about downgrading because I went though hell recently trying to upgrade from 12b to 24a. After flashing paranoidandroid kitkat rom and 24a radios I was disconnected from verizons data network for a couple of days. I tried everything and ended up on verizon's rooted 24a without data connectivity. I thought the sim was corrupt but was on vacation and couldn't go to a verizon store. Weirdly, after a few days, it simply started working.
I had a lot of charging issues on verizon's 12b with various custom kernels and decided to flash 24a - only to find out that flash is mostly broken on it. I want to flash to rooted 12b and this time not use custom kernels.
Thanks for your help.
