Harsh kernel on cm10 issue - Nexus 4 Q&A, Help & Troubleshooting

Anyone else getting the sleep of death with this ROM and kernel combo?

I get sod with harsh kernel too, ever since it changed to 4.2.2. It happens every time the screen goes off for a minute when not on charger. I never get sod with any other kernel.... shrugs

Yep same here been happening here all morning since I installed it. Pushing the eject button on this one

Never happened to me
Tapalked with a Nexus⁴

Maybe your voltages are too low? Or maybe try a different governor/scheduler combo such as Ondemand and CFQ or ROW or something. Still, I'm not sure ...

Switched to orca......loving it

[Q] tablet shuts off..

Idk if its the ROM or the kernel. I'm running cna 3.6.6 and francos r23 and the tablet will turn off after awhile of inactivity. Sounds like a feature that can be turned off but figured I would ask here instead of spamming each thread before finding an answer lol.

Do you have to turn it on while holding the power and vol down, then boot from, boot loader? If so its a sleep of death. Not supposed to happen but it does on some kernels at certain settings.

I had the same issue.... was running paranoid and alpha der kernel. I flashed the EOS ROM and faux kernel and all is right again.

Same here.. belive it was with CM + franco r23.
SmoothROM with Bricked no problem.
Its a kernel/ROM thing i guess.

Got the same issue with Stock 4.1.2 + Trinity Kernel.
On Glazed JellyBean v2 + Trinity Kernel it stoped.
My stock rooted N7 did it two or three times. Got it exchanged and had no trouble since.
Just a little thought, decided also to encrypt the tablet, just in case it turned off and wouldn't turn on again, and I had to return it in that state, without being able to do a factory reset and lose any sensitive data.

I guess some kernel settings just resulted in too deep of a sleep from nexus to wake from. Odd it happened on a couple different ones though.

Who can ease our minds? (LED of death)

I've just read reports of someone getting the red LED of death without even over clocking.. Does anyone have any good advice as to how to avoid this? I'm running aokp with _motley kernel.. Seriously thinking about going back to stock.. Am I worrying too much?

It seems like it only happens when running benchmarks.

Nexus 4 rebooting constantly...

Just received Nexus 4 from US friends to here in India. I am getting constant reboots. They are very very frequent. Like once in every 10 minutes. Generally occurring when I make calls and into it 10 seconds. Seems like its hot reboot.
I received it in Android 4.2, which I immediately updated to 4.2.1, so I have no experience if it had the issue in 4.2.
I tried the following:
1) Factory Reset
2) Putting it back to Android 4.2
3) The latest nightly build of CM 10.1
The issue existed everywhere. I also have logcat constantly recorded before the reboots. Here is one of the instants:

Any suggestions or advice? As of now I am planning to send it back to US for getting it replaced. But I want to try every possible solution in case it is a software issue..
Thanks in advance
Flash a custom kernel such as Franco. Kernel is what throttles your phone in temperatures etc.
Sent from my Nexus 4 using xda premium
Lemme try that, though CM 10.1 build kernel had the same issues.
Tried franco kernel. Still the same issue is there.
CPU Spy is not showing more times at higher frequency. Is temperature throttle possible?

I doubt these are thermal reboots.. It is probably something wrong internally that is causing it. Bad eMMC maybe?

Faux123 kernel affecting wireless charging?

Hey guys, I'm wondering if anyone knows a setting in the latest kernel (008-tbm) that affects wireless charging. I am on stock ROM with only this kernel installed. Wireless charging worked fine until I installed this kernel, so I know something is goofed up with my kernel settings. I'm UV -12.5 mV global

he doesnt have enough posts to post in the development sections.
Thank you for clearing that up for him. I hate posting stuff because everyone has to be an @$$ about helping out. If you don't want to help just move on, I don't want to hear how stupid I am just what I can do that I haven't thought of. Thanks

I'm on his 008tbu and have no issues with wireless charging.

try raising your voltages, undervolting can have create such issues. every device is different in what it likes and dislikes.
OK thanks for the help guys. I'll try that right away. Right now it'll show as charging for about five minutes and then for some reason will stop.

OK I tried that and it didn't work, I'm using the intellidemand governor and all of the rest of faux123's recommended settings. My CPU bin is nominal if that helps any.

Why do you even care? It mean that much to you?
Posts like yours are more annoying than the original threads.
Sent from my Nexus 4 using xda premium
you should try a different kernel, just to make sure. it takes seconds to flash a kernel, so that shouldnt be an issue. if it works fine with another kernel, then the issue is the kernel. if the same issue persists, then its your rom or device.

Posts like this make me believe that Reddit & Rootwiki users are right, about the attitude of many XDA users..

unfortunately, many reddit and rootwiki users arent any better.
Yeah I'm on faux's kernel as well with no wireless charging problems. There's a good chance that it might be stopping because your battery is getting too hot. Do you have daydream enabled? Does your phone feel hot when charging?
Sent from my Nexus 4 using Tapatalk 2
Yeah I just got it working for about 30 minutes and my phone is super hot. It's never been this hot before so I'm gonna try a new kernel and see what happens like someone said earlier to narrow it down if it's the kernel for sure
Sent from my Nexus 4 using xda app-developers app
What charger are you using? Some do not work well with the N4.
I have used several different kernels and none have affected the wireless charging. My phone gets up to 41°C while charging wirelessly so getting hot is not unusual.
I'm using the official nexus charging orb from Google play. I just flashed a new kernel and wireless charging seems to be back working. I'm gonna give it another hour just to make sure before I make any assumptions

One weird thing I did notice though is that on faux kernel I could not UV past -50mV without my phone rebooting, making my lowest clock of 384Mhz at 850mV. However I'm on harsh kernel right now and it shows that my lowest clock is at 800mV stock without any adjustments and is working fine. Would that make any sense? I know the governors could possibly be more or less harsh on the battery but shouldn't the failure value resulting in rebooting be the same no matter what governor or kernel you use? I'm by no means an expert as to why I'm asking

Is not unheard of to not be stable at the same voltages with different kernels. Also if you were using one of the kernels with turbo boost your chip may have needed a higher voltage for the higher frequencies. Or not, I don't know lol.
Glad your charger is working now. I like Harshes kernel.

Gs4 hot?

I just got a gs4 and am coming from the gs3. Does this phone run hot normally? Seemed warm on stock and hotter once I tried to install the freegs4 ROM. Even shut down twice.
Edit: flashed a different ROM and kernel and am all good.

Yeah I noticed when flashing certain Roms and setting it up, it gets very hot that it shuts itself off.

Not true on my part. I've flashed stock deodexed MF9 rom with Stock MF9, Agats, and Ktoonz kernel. All resulted in the phone heating up and shutting down on its own.

You might want to take it to sprint in that case, only time it gets semi hot is when im using wifi hotspot and making a call at same time on my part

So I have tried 4 different ROMs and 3 different kernels and the heat issue keeps happening. Right now I was using the latest Venum ROM and the ktoonz kernel and the phone shut off due to the heat. Stupid phone, I just got it on Sunday. Never had this issue on my epic or e4gt or gs3.

The only kernel adjustments were to the governor and scheduler (using smartass and sio, no alterations to either). I just tried using the rescan media disabler apk to see if maybe my media was causing the phone to run hot. It seemed to be the only thing going in the background.

is it heating up during usage,charging,sitting there......? have you actually physically looked at the battery to make sure its not cracked or swollen?

Usually the heat starts when I am using the phone, which is usually browsing the internet or reading up on sports news. Screen off or charging I have been OK so far. As far as the battery, it appears to be in good physical condition. I also have 2 OEM batteries by Anker that experience the same issue. So far so good, though - been using the phone moderately since the last shut down earlier today and it seems ok at this moment.

if it heats up really bad again try underclocking a step and see if that helps.....phone might be getting hot because your chip is poorly coated and the higher frequiencies are heating it up enough to shut the device down. you may have to underclock by one or 2 steps to ensure its not a consistent issue.....worth a shot anyways. unless you do high graphic gaming and multitask with 8 apps at once your really dont need the higher clock speeds anyways.

Good idea, hopefully I won't need to! Appreciate the feedback.
If you just got this phone Friday then I would return to stock, run triangle away and exchange it. What you describe isn't normal, why take a chance and get stuck with a bad phone when you are within the exchange window.

Try the stock kernel and rom and if it still get hot take it back. Try stock kernel it works man the others just cause me trouble.

Thanks all. I loaded up the latest Sac ROM and ktoonz kernwl, but disabled media scanner. No more hot issues. I guess it running like crazy in the background caused the battery to commit suicide.

Seriously guys, your S4 doesn't heat up at all???
I'm back to 100% stock everything (kernel, rom) and running this for a couple weeks. I've completed several factory resets and whatnot as well through those weeks. I know my install was clean as could be.
Now, my phone gets hot at seemingly random times. sometimes playing games, for sure while navigating with GPS and sometimes when its just sitting there. I monitor things with Better Battery Stats and keep an eye on the CPU Spy. I'm achieving deep sleep most often. Some of this is caused by the god awful Sprint service here and the constant search for signal, but I was hoping that this wouldn't get as hot as the S3.
so, should I seek a refurb from Sprint? I have the insurance. I am just afraid that a refurb would do me no better.
My biggest gripes are heating up occasionally, WiFi disconnect issues. I hope 4.3 can help some of these.
