Hi there..how to use wugesh toolkit to perform update from 4.31 to 4.4?
download the factory image, then use toolkit to restore to factory condition using factory image.
doing so will fully wipe everything including internal storage. but you get a spanking new os with no issues.
sometimes direct update will have some weird issues.
if you duwan to wipe, need to use adb to sideload the update zip.
update zip and factory image are different things.
google yourself to learn more.
