[Q] Lock Screen not working on Android 5.0 with Root - Nexus 5 Q&A, Help & Troubleshooting

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.

I'm facing the same issue with my NON-rooted Nexus 4.
Anybody having any ideas?

Mine fixed itself after I manually installed the latest Google Play Services apk. Maybe try that and see if it works for you...

[Q] Can't wake up phone after restore

Hello. I have a rooted OPO, running 05Q. Last night I finally succumbed to the temptation to flash a ROM. I used the app "CM downloader" to obtain the latest nightly of CM12. Using TWRP, I created a backup, then installed the downloaded ROM. It didn't work; the phone got stuck in what is, I think, called a bootloop. That is, it just kept showing "Updating Android" then going back to a CM animation, over and over.
After letting this go on for quite a while, I powered the phone down and rebooted into Recovery. From there I restored the backup I had created. That seemed to go without a hitch; everything looked as it did before I set out on this adventure. But when I let the screen go dark after 30 seconds of not doing anything, I found that double-tap wouldn't wake it, and neither would pressing the power button. It seemed to be still working, since notifications were coming in, but I couldn't get the screen to light up. So I did a reboot, which worked, but only until the screen went dark again, at which point I had the same problem.
So...I used Titanium to backup all apps and settings, and did a "reset to factory", then restored apps and settings. This seemed to work, but once again I found that once the screen went dark, the only way to wake it up was to reboot. And again, even though the screen was dark, the phone was working. I listened to a podcast while driving to work, even though I couldn't wake the screen up.
Any ideas what the cause of this might be? I did check the Settings to make sure the double tap to sleep and wake were turned on. Everything was as I'd left it. And in any case, even the Power button wouldn't do it.
You need to flash cm11 firmware, that is the radio and stuff to get your cm11 05Q to work properly again
Edit
You should flash this

Help! Can't factory reset/ phone locks constantly after update

Hey
I just updated to the new lolipop via the sony software I was in the phone fine then done a reboot and now it loads and get to the lock screen I unlock the phone and it locks again automatically after a second.
I cant really do anything at all now or use the phone. I dont the reboot because Wifi wasn't connecting after the update.
Ive tried doing a factory reset but the screen on boot doesnt seem to be coming up either. whats the correct process just so I can confirm im doing it right. I just want to wipe it!
I held volume key down and powered on. and the screen will just flash and reboot.. so pretty much i cant do anything to fix it
Fixed luckily I had wheres my droid installed and setup and could do a remote factory wipe! .. now everytime i open settings it stops working and crashes. anyone have any idea how to fix that?
Im trying to do a repair now using sony companion

Phone password spontaneously stopped working

I have a Samsung Galaxy S5 mini on stock rom, rooted. I was looking through Xposed for new possibly interesting modules. I installed one which said you can set volumes to have more than 15 points. So I installed it but I did not reboot yet figuring that I would do that later. I made all new backups of my apps and data using Titanium backup and then tried to reboot my phone but the reboot menu button would not work and the screenshot button at the top was blank yet functional. So I loaded up, or attempted to load up Wanam Xposed to check what was going on since that is what configures my rom and it said the app was not installed when I pressed on the shortcut.
So I rebooted the phone, entered the encryption password, it came up to the lock screen and from that point it would say my password did not match. I tried every password I have ever used, varying case and everything. No password worked. I had not manually changed it either. I had no choice but to factory reset the phone and format the SD card. Also I should mention that when I found out that wanam xposed was not seemingly installed any more, I attempted to install it and it would just say "App was not installed" or something. Then I installed Wanam Toolbox or something, I forget exactly now, but that installed and I rebooted and that's when I noticed my lock screen password was not working.
Any ideas on what the cause may have been and what things I could attempt to do if it ever happens again? I thought there was a thing where you can use your google account to unlock the phone but I could not get that thing to come up.

Black screen after Model logo

Hi guys, I hope that somebody can help me I'm experiencing a black screen after the model logo. I think that the mobile still works (I can connect with Smart Switch, the alarms ring, the touch is working).
It has happened after the mobile has freezed and I've forced the shut down. Now I'm able to use the recovery and I've tried to wipe the cache, do a factory reset and flash an original firmware with Odin.
Do you have any other ideas? The mobile has the developer option not enabled and it's not rooted. Thank you
I'd like to try to flash a new kernel. Do you have any ideas how to enable the OEM unlock option? I could use a keyboard to navigate in the menus but I have no other mobile to check the steps.
If it helps, I've changed the screen because it was cracked, I've used it a bit and then the mobile has freezed trying to open an app. I had to force the shut reboot with the screen still working and after it I've started experiencing this problem.

Interface restarting after screen unlock

The phone has completely run out of power.
I charged it up, turned it on. But after I unlock the screen, after a second the interface starts rebooting. That is, not a complete reboot, but exactly the interface, a few times, and then a complete reboot.
I can use the curtain, turn on and off wifi, but until the phone unlocks.
I tried resetting the cache via recovery, it didn't help.
I also put the latest update through odin with save data, that didn't help either.
Really need to save the data of one installed app. Please, if you know what you can try, advise me.
Was thinking of updating one ui via adb sideload in recovery, but don't know how.
