I Googled - looks like the problem is unique to my Honor 8 (L04). When I unlock the bootloader after updating to Nougat (bootloader gets locked again when OS is updated), phone's launcher goes missing. I only see a blank screen after the phone boots up - all app icons disappear. However, I can pull down the menu from notification bar on top and access settings and other options. I tried making other launchers as default, but no luck. The phone works fine when the bootloader is unlocked while it runs on Marshmallow though. Has anyone experienced this? Please help. (I am not an expert in meddling with twrp, root etc., though I manage by following instructions.) Thank you.

So, basically I am at a loss. I ususally spend enough time on problems like this until I solve them myself, but now I really need the help of others.
I rooted my Xperia X10i, installed some custom ROMs, everything went fine. The phone was still a bit buggy though, so I decided to go a step further.
So I unlocked the bootloader (using some threads from this forum), and had no issues with that either.
Then I installed the custom DoomKernel from here (the failsafe one!):
http://forum.xda-developers.com/showthread.php?t=1253853
It booted just fine, but I noticed I had no Wifi and my SIM card wasn't recognized. So I installed the Wifi modules that can be found in the same thread. I'm not sure which ROM I had on the phone at this point, since I tried many different ones.
The problem is now, that when trying to get the Wifi working, some time after a reboot the phone would ask my pin-code, and after that just gives a blue screen, instead of the usual home screen. I can slide my status bar down, and from there I can access some things, but not much. Basically I can only see that the phone does't seem to recognize my SIM card (even though it asked for the code?) and my wifi doesnt work either. Without a home screen I can't open my apps or anything.
I have since tried to install different ROMs. Again only the status bar works after a boot, besides that all I see is the standard background. Some ROMs can let me turn Flight Mode on from the status bar, and when I click it everyhting works again (except for any wifi or service, of course).
I have also tried to flash different kernels since, but nothing changed. So I used the SE PC Companion to get back to all the official SE 2.3.3 stuff. Still only the status bar works. I can still flash kernels and ROMs and boot into them succesfully, but I will always get a blank screen with just the status bar after tying my PIN code.
So... does anyone have a clue how to solve this issue? Any way to COMPLETELY restore all the phone's software, since updating or repairing using the PC Companion leaves the real problem untouched? Many thanks in advance!
Ok, resolved the issue. Apparently something went wrong while unlocking the bootloader. Restore it by clicking on "Restore" in the newest S1Tool (older versions don't have that button) and everything is solved. Just note that if you have a kernel running that requires an unlocked bootloader at the moment you restore the bootloader, obviously your device won't boot any more. Don't worry, just flash another kernel in that case.
Hi,
I'm using an unlocked Nexus 5, and flashed as soon as the factory image was released. I used CF-Autoroot to gain root access.
The problem that I'm having is that the lock screen does not work. This means that when I lock the phone (power button), it just fades to black, but when I hit the button again (either immediately, or after a wait), I go straight to where I was, the lock screen does not activate no matter what I do. I've tried letting it time out, still no luck.
When I restart the phone, it shows the lock screen, but sounds like something is trying to unlock the phone, and the phone then unlocks and doesn't lock again. I've tried disabling all Device Administrators, with no luck. I tried a factory reset and then a re-flash followed by another factory reset, and the problem still persists. I've also tried toggling Smart Lock on and off, still no change.
If I go to the security settings and re-select a Screen Lock mode, then the lock screen shows up again, but after I unlock, it goes away never to return.
This has been extremely frustrating, since Smart Lock was one of the features I was most looking forward to. Does anyone know what could be causing this?
The current Root apps that I use are:
1. SuperSU (obviously) 2.23 BETA
2. BusyBox Free
3. AutomateIt Pro
4. Greenify
5. Power Toggles
6. AdAway
7. Titanium Backup
Another note: After the factory-reset, wipe, flash, factory-reset that I did, I restored all non-system Apps and data with Titanium Backup. Just putting this here in case you guys know of any app that causes this problem.

Mine fixed itself after I manually installed the latest Google Play Services apk. Maybe try that and see if it works for you...
Hey there fellow XDA'ers, I seem to be having an issue with my XT1032 right now, it was working fine up until last night; for some unknown reason, when I tried tapping on the Network icon when you pull down the notification bar from the top of the screen to toggle my Mobile Data, it didn't do anything, just went back to home screen. So then I tried rebooting it and now says No SIM Card (and did try turning it off, take out the SIM, reinsert it and turn it back on), and all of my recent apps are still there. Usually none are in 'recent apps' after a reboot, and when I tried to go into Settings then tap on 'More' (under Wireless & networks section) it does nothing (but just force close I guess?), and goes back to Home Screen. And well now it won't boot past the Bootloader Unlocked Warning screen, it doesn't loop though so it's not caught in a bootloop, but I don't know what the hell happened; nor have been able to find a fix for it. It was rooted, but had to flash the Stock ROM then did the OTA updates (it was @ 4.4.2 while rooted then OTA'd up to 4.4.4, then 5.0.1 then 5.1) and there's no custom Recovery either, so it's all stock right now. Any suggestions? Thanks!
Hi,
I've got ZTE Nubia Z9 mini with a stock rom of Android 5.0.2. Today I have clicked power on button and I saw the clock is on a wrong place. I've restarted the phone and get powered off few times. I've also tried some custom screen locks and launchers without any success. because while using custom screen lock I have to disable default lock screen but I cannot do that because I have my certificates on the device and when I do that android deletes my certificate and to upload them again I have to enable PIN etc. How can I bring it back. I have already clean personal data from nubia launcher but this didn't help. Factory reset of course is an option but it is as a lat position on my list. Getting xposed framework is not an option for me because I don't have custom bootloader. Please help ....
Hello,
I know this has been covered briefly before but I'm trying to look for a solution to a problem.
My friend has been given an ex display s8+ to use, as the company he works for normally just throws them away.
It is on oreo, and as with all Samsung display models, it's locked down with Knox and custom locker. I can't restore the phone (even the lock screen method doesn't work), I can't install play store, I can't root it with adb, and I can't access download mode. I can access recovery, but again factory reset is blocked due to mdm protection.
I feel I have exhausted all areas, so I'm reaching out to see if anyone else has any ideas?
Thank you in advance.
