[Q] Unable to change screen lock after update to 4.4.2 and factory reset
I am unable to change the screen lock on my I9505 after upgrading to Android 4.4.2. My screen lock is currently set to Swipe, however when I want to change my screen lock to something else, all options except PIN and Password are grayed out ("Turned off by administrator, encryption policy or credential storage"). "Swipe" is also grayed out which is strange because my currently my lock screen is in fact set to swipe.
I have done the following things to my phone:
1. Upgrade from T-Mobile (NL) branded 4.3 to unbranded 4.4.2 (NL) using Odin, downloaded from sammobile. In the past I had installed a custom recovery and rooted my phone, but this was removed after installing 4.4.2.
2. WiFi did not work after this, so I applied a WiFi fix using Odin (I9505XXUFNB8-WiFi-FIX-(NON-HLOS)). Unfortunately I cannot find the original thread that describes this fix. If this is relevant I can search again. Wifi now works.
3. Factory reset (boot into recovery -> "wipe cache" and "wipe data/factory reset").
As described in other threads: All device administrators are disabled, nothing is encrypted and I have cleared credentials. I also tried removing my sim card, but the screen lock issue still persists.
When I boot into recovery it says:
-"Applied the CSC-code: PHN" (this used to be TNL when I still had 4.3)
When I boot into download mode it says:
-Product name: GT-I9505
-Current binary: Custom
-System status: Custom
-Knox kernel lock: 0x0
-Knox waranty void: 0x1
In About Device it says:
-Baseband version: I9505XXUEMKF
-Build number: KOT49H.I9505XXUFNB8
-Secure boot status: Samsung
The firmware information on sammobile:
I would like to know if there is a way to fix my screen lock issue. I suspect that my problem is caused by the wifi fix or the unbranded firmware because it still persists after a factory reset.
