Congratulations SlimLP to the birthday
Today, the newest weekly is exactly 2 months old :D
KK is most, let my call it "out" . There will come a last stable build, maybe before a weekly, but huge work on KK will no longer happen.
Ok, I'm waiting for a stable KK 9.0
Maybe in a month then comes the switch to Android 5.0 (SlimLP)...
The trick might be:
You have to do the right factory reset ;)
After flashing Stock (before flashing a custom recovery!), you have to boot the device.
Go into settings => Backup&reset and do there the factory reset.
This is the deal. That worke...
Thanks for the new Build.
I hope there are no "Easter eggs" installed. ;)
