Same here... S-Off, Stock recovery restored with the All-in-one Toolkit. Trying to apply update -> at about 20% of the progrss bar the red triangle shows. Automatic reboot after like 2 minutes.
EDIT:
The home button brings me to the recovery, saying:
I was under the impression that i made a backup before deleting, but can't locate it... Anyone can share the 7digital3.0.apk?
If I am right, I deleted more useless stock installed apks, so there might come up more missing apks...
How did you S-OFF?
