[Q] Unfortunately, com.keyguard has stopped [black screen] - Droid Ultra Q&A, Help & Troubleshooting

I can't do anything once it boots.
Factory reset lets me get through the setup process, but no home screen or anything..
reboot leads to "Unfortunately, com.keyguard has stopped" and keeps popping up. literally stuck.
Rooted 4.4 out of the blue this morning bootlooped when I turned my phone on this morning.
No xposed, ART enabled.
Again, factory reset from stock recovery gets me nowhere. Is there a way I can completely wipe whatever is causing this? Still no FXZ for 4.4 right?

Others have fixed issues by putting the 4.4 update zip on their sd card and running it again, repairing system files and keeping user data. Possible?

Here is the fxz: https://dl.dropboxusercontent.com/u....4-SU2-3-15-release-keys-cid2-Verizon-US_.zip
Extract the files, put your phone in fastboot mode, run the flashall.bat

Factory data reset doesn't reload the OS as far as I know I have ran a FDR and not lost root. It deletes all user data like apps downloaded and pictures etc. So it won't fix an OS error only an FXZ does that. It basically strips all the stuff you downloaded to factory settings but doesn't reinstall the OS.
Did you have SS inistalled and not make a backup or did you not have SS installed. If you can get to SS you could load a backup if you had one.

Yeah ended up using that. Just happy to have a working device again despite no root anymore lol
Thanks a ton guys

[Q] Factory Reset issues NOT ROOTED

Just got this brand new looking RAZR MAXX HD. Tried doing a factory reset and it took close to 20 minutes on the android screen with the open chest and blue bar at the bottom. I proceeded to boot it into the bootloader and then i chose NORMAL REBOOT and it booted back up fresh. All was SUPPOSEDLY well, until I rebooted it and now it starts a factory reset all over again on each reboot. I have to force it back into the bootloader and reboot it normally. Upon full reboot I have yet another factory reset phone. losing ALL MY APPS and documents. WHAT IS GOING ON? Please help. Im on a Mac too so if I need a computer, lets try to make it work for the Mac. Lol. Im very good with ADB and FASTBOOT and have those set up on my Mac as well. Thank you....

[Q] Phone won't boot

I've been having spontanious reboot problems where my charge would reboot and get stuck in a boot loop freezing on the droid eye animation and rebooting. In the past I've been able to clear the delvic cache and regular cache and get the phone to boot and go back to working order. Today however, clearing cache didn't work. Thinking this was a software problem, I connected the phone to oden and flashed the stock software ED1. I was planning to install back to EP5 and redo Tweaked 3.2 since the phone had developed a lot of lag.
Now the phone gets to the droid eyebll and stays there. Every so often the animation freezes for a second or two then continues. Is the phone dead? Can it be brought back to life so that I can use it while I figure out a new phone. I'm asking because this is my only smartphone and I'm now stuck activating my old chocolate flip

Why all the way back to ED1? Do you have everything backed up in case you need to flash with the pit file?

No, the phone is not dead, it is a bit lag.

[URGENT] Every reboot results in a factory reset

So today my droid started messing up, home and recents button didnt work. Google play store and whatnot couldnt access data, the signal status bar at the top was just grey.
So i factory reset it. During the reset it just sat there on the little screen with the spinning hexball thing for like an hour so i shut the phone off. Now every time the phone boots it just tries to wipe it again unless i go into the boot menu and hit normal boot.
Running stock rom and whatnot, but im rooted.
I know that theres a flag somewhere that it reads on boot saying to wipe it, but dang if i know what to change.
Thanks in advance
Well i unrooted my phone and tried to let it redo the factory reset again, and it still just wont do anything.

When this happens to me, it's because of a bad flash and a factory reset won't fix it. I would suggest reflashing stock...

I dont have a custom recovery or an unlocked bootloader.
I managed to get the problem sorted out through some unrooting and some non stock system file deletion. Installed safestrap and got blurry hd running on it now.
Thanks.

Unfortunately, Android System has Stopped! Help Please!

Last night I decided to switch to ART from Dalvick runtime. Ever since, when android finishes loading, I get the error message "Unfortunately, Android System has Stopped." I've tried returning to stock (I'm rooted) and neither of my windows computers can see my phone which is weird because I unrooted my LG G3 recently with no problems. I've performed a hard (factory) reset numerous times. Sometimes the android system loads up OK but as soon as I reboot or power down I have the error message again. I'm at my wit's end. I can't return the phone because it's still rooted and I can't get it to work. When it boots, the LG screen appears normally. The At&t screen appears normally. Please help! I'm desperate.
If you're okay with losing info, give this a shot. I'm not sure exactly why it's doing this unless you had xposed framework before. Anyway, follow the steps and it should fix it. I'm not sure if you've tried going into the boot loader yet and doing a factory reset through there. So you can try whatever you like

I can't get a computer to recognize the phone. I have tried a hard reset and I still get the error message. Any other ideas?
I had the same issue after I tinkered with something I shouldn't have tinkered with. I think I installed GravityBox, didn't like what it did, tried to factory reset, and started getting the Android System error consistently.
That link mcnick posted will serve you well. I would however use this thread since it's tailor made for the AT&T variant.

Please help me stop factory reset on android?

I really need help! Friend was messing with my phone and selected to factory reset it. I quickly grabbed it away but it already began to reboot, however I did not let it reboot. I forced it off.
Any chance I can still stop the factory reset process? I have TWRP installed but seem to be getting the factory reset splash screen when I hold volume down+power.
Has the damage been done, or not yet? Please tell me there's a way to bypass the reset. I do not have a removable battery.
Get to recovery mode and backup your phone and reboot. That's the last option I guess

How do I enter recovery without the factory reset from starting?

If you turned off, you already stopped it. It will not try to continue when you reboot the device. But, there is no way to know if anything was wiped or not, until you reboot the device and find out. If it wiped anything, it's gone, unless you can use any of the various data recovery programs on PC to recover the lost data, if it is possible to retrieve it.

I heard that the factory reset is "locked" into your phone as soon as it turns off, but it doesn't begin the process of wiping until after the first boot. I think I have partially confirmed this because when I try to boot, I get the android updating splash screen, which I guess means it is about to wipe. I force it off as soon as I see that screen, but before the phone has time to officially begin any process, so I am unable to boot into android or recovery.
Is there a way to mount my internal partition to my PC without turning the phone on, like through fastboot?

The reset was already started, you originally interrupted it before it could "finish" the "wipe" then, when you rebooted, it is starting the "reload" process(android is upgrading) where it loads the system and whatever personal data is still there, if any personal data remains from the interrupted wipe.
As I said, all you can do now is let it finish booting, then use data recovery software to hopefully retrieve your lost data, or take it as a learning lesson if the data is irretreivable.
