Is there any possible way for ME7 to get upgraded to kit kat and keep root? i keep seeing pages where 4.3 can get upgraded but nowhere with 4.2.2
Safestrap 3.71 is fully functional on the SCH-i545 on Jelly Bean (Android 4.3).
There is no Safestrap release for Android 4.4 (Kit Kat) unless you use the 3.72 release from the AT&T phone. That's known to not work properly on the Verizon phones, but several people have managed to use it to support a 4.4 upgrade while retaining root. Those are complex upgrade processes that require people to carefully follow the upgrade process. There's apparently a large number of people who can't manage that process successfully.
Read the several MK2-to-NC5 upgrade threads. Decide if you can be disciplined enough to follow those processes precisely. If not, wait for a native NC5 root technique.
