I unrooted to install this update. I notice no difference besides the fact that I cannot regain root access using framaroot. It's same version of JB. I have yet to attempt another root method such as adb yet.

There is no root available for this build. Nothing works. Ive tried all old methods. The end

Believe it or not, on 11/10/2015 I rooted my one touch with Framaroot, then downloaded and installed the updated build to JB 4.2.2 (L31UM11) from T-Mobile and so far I'm having no problems. The phone is acting as though it's been defibrillated!
