So I forget which recovery/bootloader I've used to root this Sprint SPH-L720 Galaxy S4.. I believe it is from shabbypenguin or something.
I love the root features such as adblock, native hotspot, etc, but I need KitKat..
I get a notification that says System update downloaded - Touch to install.
It is the MF9 Android System Update. It crashes on the bootloader whenever I try to upgrade.
My phone version is as follows:
Software Version: L720VPUAMDL
Hardware version: L720.08
Model Number: SPH-L720
Android Version: 4.2.2
Baseband Version: L720VPUAMDL
Kernel Version: 3.4.0 shabbypenguin@Minty-Fresh-14 #1 Wed May 8 11:08:56 EDT 2013
Build Number: JDQ39L720VPUAMDL
Is there a way I can upgrade to 4.4 on this phone without doing a hard reset?
Bootloader Error when I pressed restart and update (yes i typed out the output..):
