I've read about it but most of the problems were with people who rooted and flashed a ROM. I'm on stock firmware (MF3) no root. I would unplug my phone from the charger and it would freeze. After trying to put my unlock code in it'll open up and say “process system isn't responding." Anyone know anything about this?

I have a problem with my nexus 4. I noticed that my phone sometimes is getting slow and then I can't do anything, and after a few seconds there is a System FC window. Only reboot helps me.
I use official 4.3, no root, even bootloader is locked.
Any ideas what can I do?

Try a factory reset after backing up everything, that usually solves the problem. You should try it in recovery first, wipe everything. After that do a factory reset in Android. Should work like new. I had problems after installing 4.3 (FC, lags and playstore not working) the factory reset solved it.
Oh, I hope it'll help me.

Short version: phone won't boot, won't go into download mode, won't properly do a factory reset (tries but doesn't do it), need help.
Finally bricked my phone after tampering with it too much.
I was on the stock KK rom released by LG themselves, no root. Reverted back to the 10c firmware, OTA to 10g, rooted and installed TWRP - flashed a Vodaphone Germany KK ROM for the LG G2 because I heard it had minimal bloatware and no bluetooth wakelock unlike the KK version I was on for T-Mobile (my carrier). It had the touchscreen issue which I never experienced before. Tried multiple times to go back to any T-Mobile LG G2 ROM using the LG Mobile Support Tool - no dice. Uninstalled and reinstalled everything twice. So I figured, oh hey, I probably need to use the Vodaphone Germany JB.kdz file, root that, install TWRP, then flash back to the T-Mobile KK version that I had before. Seemed fool proof in theory. Used the LG Tool to do such, it finished smoothly and now my phone won't boot. It won't do a factory reset (it enters the factory reset mode and it attempts to do one but just reboots). It won't enter download mode either. I think I'm screwed here. Any advice?
I found 2 guides, but to even begin to do the first one I need my phone to enter fastboot mode and I can't find out how to do that anywhere.
you say Won't go into download mode? What happens when you try?
It just shows the first screen as it tries to enter download mode, with the blue dots. The screen that comes after that doesn't happen anymore. It used to switch to it after a few seconds and then the LG Mobile Support Tool could connect to the phone, but it can't anymore.

would you PLEASE fix your posts so the signature is at the bottom?
The same thing is happening to my ls980. I'm certain it's hard bricked. Download mode shows on the screen but won't boot into firmware upgrade screen. No recovery at all. Os will not completely boot but does show on pc as LG modem. Think it's totally done for. Let me know if you make any progress because we both have the same problem.

Didn't work for me. Windows and Ubuntu didn't recognize my phone. I actually ended up ****ing up my laptop by overwriting a partition but that's on me.
Decided to take it in to a T-Mobile store and blame it on the Kit Kat OTA. It turns on, doesn't boot, doesn't factory reset, doesn't fully go into download mode - how are they gonna know I ****ed it up? I have basic insurance on my plan because the JUMP program is tied into it. So for a little over $10 a month I just gained access to a warranty exchange of my device which is set to ship overnight. Can't wait. Huge stress reliever. I advise you take your phone into your carrier store and do the same as I did.

So did they fix it for you under warranty?
or they figure out that you root it and play with it !?
because I'm having the same problem with my f320k and I'm thinking to send it back to Korea
Same is the case with me, my phone is dead for more than 20 days.
here are the details if any one can help?
Im wanting to know if there is a way I can unroot without having to delete everything on my phone. I have tried the update twice already and it goes all the way to the little android guy and loads about half way and then restarts the phone and nothing changes im still on ZVA. I think the issue is that I'm rooted. I have stock everything aside from that even recovery Is stock. I really hope there is a way to unroot without having to reset my phone.

Try opening the superuser app and there is an full unroot under settings. Do not know if it resets the phone or not, I have never done the unroot but I would think it would not.

It doesnt reset, you dont even have to restart.
Team work! Gotta love it.
Even unrooting didnt help. When I try the OTA it only goes 1/3 of the way and then it reboots. Is there anyway I can update manually?
Sent from my LG-LS980 using xda app-developers app
Did you download over wifi? Might not have gotten the full download.
Did you also alter the files for free tether? If so, did you change them back before try to unroot and update?
I did dowoad over wifi and over LTE and still cant seem to get the update to go through all the way. And no I didnt do the tether hack.

Hi I rooted my brothers Verizon Samsung Note 3 which was on 4.4.2 NC4, Installed the safestrap recovery and have setup Hyperdrive on rom slot 1. My problem is when I try to access the stock rom slot it hangs at the Verizon logo. I've pulled the battery and same result time after time. I flashed a prerooted de-odexed 4.4.2 nc4 stock rom to the stock slot and it still hangs at the Verizon screen. Today I tried to do a factory wipe on the stock rom slot to see if I could flash another rom to it and it said it could not mount /system and /systemorig. Can anyone provide some info as to how I go about fixing this so he can have his stock rom back? Thank you.
Odin back to a stock ROM, non-rooted. If you want to, you'll have to start the root process from scratch.

That's what I figured the answer would be. I do have a 4.4.2 NC4 non rooted stock to flash. Thank you for your help.

One thing you might try first. I don't know about your initial problem getting stuck at the boot screen. But I tried the other day to do a complete wipe and wound up with the "unable to mount" errors. I had to go into the Mount screen in safestrap and uncheck all boxes, then recheck everything. For some reason, I had to click the System box several times to get the checkmark to show up. Might be worth a shot. Helped me avoid the hassle of having to odin back to anything
When I setup the 1st custom rom on the sd card I accidentally did a full wipe and after that I've been getting unable to mount errors like you stated. I will try that this weekend when I see him. Thanks again for the help and I'll report back with the results.

Clicked system for 10 minutes and the check mark will not show up.

Sorry to hear that. I wish I knew more about the error. Or the "mounting process" that seems to have failed. It was only by luck that I figured it out on mine. I was already downloading the files to odin my phone back and start over when I lucked out. Figured I would pass it along before you had to lose all you had done. But I'm not sure what else you can do at this point. Maybe someone else will chime in.
I was able to successfully recover from a "hang at the Verizon logo" soft-brick on my NC4 4.4.2 Note 3 by following the directions in this thread: http://forum.xda-developers.com/showthread.php?t=2483380 It seems like it might be worth a shot.
I tried flashing 4.4.2 NC4 non rooted and now it just hangs at the Verizon screen. When it boots up it still shows the custom logo under the Samsung Note III logo as well. What can i do or is it time to get a new phone? Thanks.

i'm having all the same issues you are... I cant even install new custom modified or non note 3 apks... you may have to factory reset one more time after ODIN.
I can't even get into recovery to factory reset it. We destroyed it. Lol. Just going to buy a new phone.

Replaced the phone but I'd still like to see if I can fix this one.
Does anyone have a prerooted 4.4.2 NC4 tar.md5 or other tar.md5 that I could flash in Odin? I have tried the stock 4.4.2 NC4 tar.md5 and it still just hangs at the Verizon screen and it just reboots when I try to enter recovery to factory wipe it. I have the 32g pit file already. Thanks.

Rooted a friends note 3 so he could be free from lock down and now he wants the note 4. Tried to unroot it by using the feature in supersu and uninstalled safestrap and when i went to show him how to wipe it in stock recovery it wouldn't go to the recovery. Trying to avoid using a computer if possible and Odin back. Anything I can do?
Sent from my SM-N900V using XDA Free mobile app
OK I think I know why I couldn't get into stock recovery but I have another question. Is unrooting using supersu and wiping data and factory reset good enough to send the phone back in for trade if I didn't install any roms just rooted or will I need to Odin back to stock?
Sent from my SM-N900V using XDA Free mobile app
I generally find that it is easiest to use Odin and the stock firmware (make sure it is the right firmware for the version of android that is on the phone). It will remove root and put the phone back to the condition it was in when it was purchased.
OK so I used Odin and got his phone back to stock but it seemed to have deleted every photo he has taken in the past 5 months. Does anyone know of a way to get them back without having to root his phone again?
