[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.

Other information:

When I boot into recovery it says:
-"KOTH49H.I9505XXUFNB8"
-"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:
-PDA: I9505XXUFNB8
-CSC: I9505PHNFNB3
-MODEM: I9505XXUFNB8

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.

Problem is that u have wrong MODEM. You will have to flash I9505XXUFNB8 modem for solve ur problems. But I think this maybe void ur warranty. The best u can do is make a full wipe and flash again full stock I9505XXUFNB8 firmware through ODIN and take a look if ur baseband changed

This solved my problem. The baseband changed and now I can change my screen lock.

Thank you very much!

What I find strange is, I just repeated the same flash procedure I did before. Why wasn't modem updated during the first time I flashed new firmware?

Hi,

unfortunatelly this did not work for me. I flashed the modem to the correct version I9505XXUFNB8 and it still gives me no option to turn on the lockscreen (grayed out saying "Turned off by administrator, encryption policy or credential storage", like for the OP). Actually, I think I have had pretty the same problems as the OP, incl. having no Wifi after flashing 4.4.2. I could fix this by flashing Adams kernel 2.1. I guess that Wifi fix would also have done it, but I didn't try.

Well, I tried pretty much the same things, nothing worked. Unfortunatelly, also flashing the modem to the correct version did not help either.

I even made factory reset and flashed stock 4.4.2 rom again, but apart from having no Wifi (as written before) I still do not have a lock screen.

So, I am stuck now. Any ideas what else to check? Please do not tell me to do factory resets since I did that a hundred times already

Well, I'd rather not install an india firmware that may or may not work for me but which I cannot possibly understand (other language and stuff).

Anyway, in the Adams kernel thread I found the solution for the lockscreen problem: Edit the /system/build.prop file:
