Having the same issues on Cyanogenmod 4.4 . It doesn't happen often, I guess twice a week.
This didn't happen on 4.3 though

thanks a lot. I'm not alone I think this is about root. Because my friend has a Nexus 4 with full stock (no custom rom, no root, no kernel) He doesn't have the same the issue.

could be the custom kernels though, or did you have that problem with stock kernel as well?

I have never used stock kernel but my friend uses his phone with stock kernel, he doesn't have the problem.

KtManta messed up root

After updating the latest KtManta kernel my nexus 10 lost its root capabilities, super user won't just work, it is just me or it is a known issue?
I've flashed the December version of the kernel afterwards and the problem prevails (ktoonsez doesn't include every kernel download link, a bad practice in my opinion)
I am on CM now and everything is working fine, I wonder if anyone has been victim to this weird issue

I am guessing but is this a permissions issue? I've flashed KTManta a number of times including just yesterday with TWRP and never had the issue you describe. Occasionally, right after flashing a ROM or Kernel, I have seen from TWRP a "Fix Permissions" message which I always execute. Some custom ROM/Kernels flash instructions even include a "Fix Permissions" instruction.
Also sometimes after flashing then rebooting I've had to "reinstall" Superuser so it can grant root permissions to various programs. As a habit, right after a new flash, I start Superuser once just to see if it says it needs to be reinstalled. This is not a reinstall from an apk but is a dialogue message displayed when the app is started.
As I wrote this is purely a guess on my part.
I had a laugh at the thread title. (sorry) You either have a corrupt download or something else really weird going on. A kernel wont remove root from your unlocked firmware and ROM files unless the flashing script is actually programmed to remove the files needed. Which its not.
Well this is strange, because I have fixed the permission issue and wiped cache and dalvik, not once but multiple times (I set up the kernel thrice, after it was malfunctioning).
But seeing you two replying, I set up KtManta over CM today and it is not giving me a bit of trouble, strange indeed.
btw, is it true that KTManta fixed the color issue a bit?
Yes it does fix the color a little bit.
What ROM were you on that you had this problem?

It won't cause you to lose root but it is also not really designed to use with stock either. Most if not all custom kernel users are on CM, AOKP or AOSP ROMS.

What's the difference between AOSP and stock roms?
And yes it's now working flawlessly with CM.

[Q] Nexus 4 No camera on slide to unlock and lines on display.

My Nexus 4 recently started showing these lines on the display. And the option to slide to the left to launch the camera is gone? I have tried factory reseting it with no success. Anyone experiencing these issues?
Did you flash a custom kernel? Or a custom rom? Any modifications to the phone?
That's been gone since Android 4.2. You now swipe to the right lock screen to unlock to the camera.

The phone has never been rooted. So no custom roms or modifications. I am waiting to hear back from google about a replacement.
Ah Ok. I figured that, just wasn't sure. Thank you guys for your help.

If it's bone-stock then you should RMA it.

Anybody want to try a possible fix or mitigation for random reboots?

UPDATE: don't need anyone testing this anymore as it is not fixing most reboots
Can someone who is running custom recovery and has bad/frequent reboots install the attached file and see if it alleviates your reboots?
Please let me know what version of the OS you are running and if you are on JSS15J or JSS15Q, whether you updated via factory image or OTA.
I am 99.99% sure nothing bad will happen to your system. This will not disable your ability to get OTAs, nor change any system files, nor affect touchscreen, nor affect GPS, ...
I'm running a version of cm which has worked better than stock but still a daily reboot. What is this file going to alter / Will it work on cm?

If it works, it should work ok with CM as long as you run it in TWRP.
It doesn't actually touch the ROM. It uses the kernel to reset the DDR3 memory timings and allows the system to retrain.
Thanks, I like to know what I'm flashing. Just flashed, will report back.

I'm on 15Q odex stock ROM. I never had an ota before.
I rooted and unlocked the boot loader and flash this ROM yesterday.
Just had a reboot on mine as well.
Running build 8 of this:

Ok, then it looks like this won't fix the random reboots.
Sorry, back to your regularly schedule program.

im on clean rom with elemental x 1.2 and i have never had a reboot or anything bad happen since. i did have issues on stock 4.3 with small tweaks but since clean rom i have had no issues whatsoever
Edit also was on slim bean flo and had same issues so it's something messed up in the rom i would assume and not the software version it self

[Q] freezes on 4.4.2 custom roms / kernels

on the latest d802 4.4.2 custom roms and kernels i get a lot of freezes.
it will freeze in the middle of an animation and will take some seconds up to some minutes and then working normal again.
sometimes i have to hard-reboot to get out of freeze / lag.
on older 4.4.2 slimroms i never had this behavior, only since some weeks with new roms / kernels.
i`ve tried every rom / kernel combo but sooner or later i will get a freeze again.
could a revert to stock and re-rooting / flashing custom rom maybe a solution? i`m afraid to do this because of the long time to backup my 32gb data.
what are your experiences with the latest 4.4.2 roms and kernels? did you find a solution for this with any combo or fixes?
help would be appreciated.
push! no one else with same problems? maybe i got a hardware defect?

The only thing I can say is I own the VS980 version of the device and i've tried every single 4.4 rom offered on this sight and have the same issue with all. Most of the time i'm using the device and it freezes, sometimes reboots, and sometimes comes out of it after a few minutes. Also not being able to wake the device only seeing a black screen and forced to hard reboot device. 4.3 seems to be a much better with these issues but not completely solved for me. I'm hoping the release of 4.4 source from lg will fix these issues but i'm unsure. So at least your not alone in these problems lol. I've tried multiple kernels and governors etc. Bumping up the min freq on the cpu seems to help and changing to interactive governor but doesn't eliminate the issue just help. I thought my next move would be to use lg flash tool and update to latest firmware reroot and install cwm.

i think i will do the same today after work. hopefully this helps.
the better option would be to stay some days on stock rom to ensure there is no hardware defect. but i can`t stand stock so this would be a hard route! ^_^

Yea unfortunately it seems very common among these devices so i'm pretty confident it's a software issue although i'm not 100% sure of that. I ran a flex rom for a few days on 4.2.2 and didn't have any of the same issues.
added a poll as a matter of interest.
omni-ROM, Mokee rom, vanir rom etc.freezing problem still continues.
Using CM11 (4.4.2) for 5 days with zero freezes so far.. note that this is on D800, not 802.

Yes, stock cm kernel.
I'm thinking back now and it did freeze once when first signing into the Google account immediately after flashing the ROM, but nothing after that. So.. nearly spotless
Nice! Maybe they are getting the issues ironed out. Haven't been on cm11 for a week or so since it was the worst with freezes for me. I'll have to give it another shot.

Best of luck! To be specific, I'm using the snapshot release of cm11... still don't trust the nightly releases
i did a lg flash tool stock restore, factory reset and OTA updates. now the freezes did not come back until now *knock on wood*.
when i did a backup of the sd there was one corrupt media file which was not able to transfer.
maybe the media scanner did go crazy and was the reason for the freezes.
using cm11 m3 on my d802... very little freezes compared to previous nightlies, fingers crossed

Random Reboots..

Hi!
I'm using the G900F Galaxy S5 variant and i always get random reboots when i use Roms like CM,AOSP or else.
I tried to change the rom,the build version,the kernel,and my phone firmware and bootloader.
But still it didnt change..
When i start using non TouchWiz based roms, my phone usually reboots about 5 or 6 times a day.
I don't know why.. It usually happens when i try to start any type of app.
Has anyone faced the same problems and found a fix for it?
Or does anyone know how to help me out :crying: ?
I dont have these type of problems when i use Touchwiz Based roms.

I would suggest to flash a stock firmware to do a fresh start then root and flash a custom rom , see if it works.

I have the same issue, flashed CM 12.1 ROM and installed Gapps and the phone randomly freezes for 2-3 seconds and reboots.
