[Q] D800 Phone consitantly reboots and overheats/ bootloops - G2 Q&A, Help & Troubleshooting

Ive been having issues with my d800, no matter what rom/kernel i use it randomly reboots i guessing because it over heats because it gets hot and then boot loops, i have to manually power off and let phone cool before powering on again. Also alot of the times i press the power but or double tap to turn the screen on and it doesn't come on, it is illuminated lightly but its still black I rooted using iroot25 and autorec for recovery. The most stable rom I've found was Candykat and i still get a reboot every once in a while but it boots right back up. I've tried re flashing tot/dll with lg flash tools a couple times now that works fine, and rooting works fine. its just about any rom i use it has issues, could this be a hardware issue? Also Ive tried cwm/twrp/philscwm recoveries and that didn't make a difference. i am using d800 roms just to clear that up. any help would be greatly appreciated.
Baseband version- M8974A-AAAANAZM-1.0.190082
Kernel version- 3.4.0-slim-4.4.2-kk+ [email protected] #1 Fri Jul 11 20:41:49 EDT 2014
CandyKat version- Ck-v1.5.5 Official-20140711
This is my current setup and it seems to work the best, also im not using a kernel tuner right now.
Please ask if you need more info.Ill try to get a logcat if someone can help. im not new to this and it just has me stumped.
Thanks Matt

Anyone?

Hello, I'm having the exact same issues like you, I have my phone for over a year and started with this problem, I have the last Optimus for the AT&T version, do you find a solution?

Yes, well sort of. I sold the phone and they took it apart and apparently the person I bought it off of, had d800 factory covers and the internals were d802 and it also had an d800 ROM so I didn't know ant different. But I'm not sure if that's your issue or not

Sometime just cooldown the phone by Puting it in a plastig bag and in the freeze sova that.
Thermal don't load properly during boot.

yup, i had this after running a custom rom for a few days. i'm sure it wasn't the rom though, i restored back to stock last night just in case, we'll see.
However, in the future, please also post your ROM, kernel, etc.
For example, having your phone OC might result in such random reboots...

I didn't change the kernel and I don't want to name the ROM because I'm sure it's not its fault - it was fine for a few days with plenty of reboots and activity/usage. Sounds like others on stock have the same problem (not necessarily related to the camera issue), so I've gone back to my stock backup and will see what transpires.

I understand you, but it is not like blaming the ROM creator. Is that you might have discovered a bug, and you can help to get it solved.
personally, the first thing I would do is to make a factory reset. This is not the case for you any more... but however.
Good luck and please tell us got things go on...
Fair enough, it was slim bean build 6 on Verizon. I reverted to my stock twrp backup last night (10hrs ago) and been fine so far...

[Q] Canadian Variant [SM-N900W8] Stuck In Boot Loop!

I've been reading through other threads here on XDA about a common boot loop issue that N900T users are experiencing, but nowhere was it mentioned that the Canadian variant users had a similar problem, but I do.
I was wondering if there were any other SM-N90028 users out there that were stuck in a boot loop?
Here is my situation:
I have a Canadian SM-N900W8 (it is, also a Qualcomm LTE version) and I'm in a boot loop... it all started when I tried to restore a Stock-Rooted Rom with TWRP.
I can't, however get it out, and I've tried all of the versions of TWRP, I've also used odin like 30 times... nothing.
I successfully restored a Rooted stock ROM through TWRP, but it wasn't until I re-installed a factory un-rooted one that things got ugly..
So I was thinking about this and perhaps the cause of this is KNOX... since the first thing I did when I rooted my phone initially was uninstall KNOX and all of its files. I know these didn't carry over when I did a TWRP backup, which is perhaps why my restore of that backup worked the first time. The second time, I just went and downloaded everything stock and used Odin, and that's when the bootloop occurred.
if anyone knows of a way to solve this, I'd be forever grateful!
I really hope I will be able to fix this...
Not to sound.to xdaish...but dude seriously this topic.is all.over the n3 forums. Have a.look and you will find tons of info.
Also...good idea to.read prior to flashing..if you had you would have know not to restore with twrp since it causes bootloops.
Just trying to you some friendly advice.

Thank you, but I've read them all and most are regarding the n900t, I felt it appropriate to ask about the n900w8 variant.
Also, I know that would have been better, but it's too late for that now. I just thought I'd share my experiences here with this issue so that others will know better.
So I tried a different stock ROM, and with the latest version of Odin, but it still is in a boot loop.
However there is one difference; this time it will boot past the Samsung logo and into android, but then a window will pop up saying "Process system isn't responding" and ask me to wait for it to respond or close it. Regardless of what I select, it will end up rebooting seconds later.
In the very short time that everything stays booted for, I can access the two pull-down menus from the top, but selecting anything will yield me no results.
Perhaps this can tell us more about this issue?

[Q] D800 - No recovery - Unable to flash in DL mode

So I'll start by saying I made a boo boo and this is 100% my fault.
I rooted my stock D800 and flashed TWRP. I flashed Cyanogenmod but where I messed is up when I flashed the D802 ROM and not the D800. I figured I'd just boot into recovery again using the hardware buttons, but all that happens is the screen turns on but nothing actually displays.
After that, I figured I'd just flash a stock ROM and basically start over using Download Mode and FlashTool. Unfortunately, I can't flash the stock firmware because the phone is NOT identifying itself as a D800, it's identifying as a D802, so FlashTool will not allow me to flash the proper files.
What I don't understand is why was I able to get into TWRP that one instance and flash the ROM but now whenever I attempt to get into recovery again the screen just turns on but recovery doesn't show. Makes no sense to me. I've tried getting into recovery using the hardware buttons a million times after but no dice.
I know it's not much, but I'm willing to throw in 10 bucks via PayPal for whoever can help me fix this.

Im in the same situation as you bro. Tried to use LG flash tools to flash my sprint back to stock and its detecting my phone as a d801. No help yet
same here from 2 weeks..
EVERYONE! I have found a resolution for this.
First, visit this thread.
Download the DLL from this post and flash with a normal stock ROM. I used this combo and it flashed WITHOUT issue. Hope it helps you guys out as well.

So it doesn't need to be in FAQ somewhere?Lol it would've helped me out dramatically! It's not my fault that there are recoveries that mess up your phone. Coming from Samsung phones I didn't think that someone would release faulty software that would render your phone unusable.

[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

And what happens when you DO NOT overclock or undervolt? Some devices frown upon undervolting, lets use the default settings and monitor it from there....
Good luck!
Thanks
I face these problems even on stock settings...just after flashing kernel
