phone heats up and restart with all custom kernels

has anyone else experienced this? i have this happen to me quite a few times using bullet/synergy kernal
basically what happens is that my phone will always heat up and crash then it restarts itself..even when it's idle
i've used faux clock to keep my phone from ocing but this still seems to happen..

Try Fauxs kernels.. always stable....check your OC setting and UV settings...flash it and use at it's out of the box setting

oc settings is set to keep the clocks at stock
i tried undervolting it by 12mv and my phone was ok, then i went a bit lower and my phone crashed again, not quite sure if i should try another custom kernel, i feel like im on the brink of bricking my phone

Yeah..not all chips are created equal...so keep it to where it's stable and you should be good. Flash Fauxs.. leave all the settings as it came and see how it does for you

i dont think its actually a chip issue
my settings were
1.512ghz max 384mhz min
and
at screen off
540max
384 min
my phone heated up and crashed when i turned the screen offf..so it seems more like a software bug rather than hardware imo..
i think you misunderstood me lul. so here's the entire story
i flashed synergy a couple weeks back and had this issue, so i thought o well and went back to eaglesblood(which is pretty much stock everything)
then i decided to try jugs+bullet, it seemed fined until i went to sleep and wokeup with a phone that has its battery drained and is hot to the touch
now the settings were set to not overclock, so it doesnt seem like my chip is causing the issue

If your chip heats up enough to cause it to crash and reboot...that's not a good sign man..especially if you've tried different kernels and don't have crazy settings.
One more flash won't hurt right?
Maybe try a new combo... different rom and kernel?

im on faux right now
it does sound bad, but its been fine when im on eaglesblood(stock kernel)
so im a bit confused all around

thing is, im playing gta 3 right now and its barely heated up, so it confuses me why it would heat up and crash/restart when its friggen idle..

Like some are saying try faux's kernal. I used to have the same problem when ocing my sgs and g2x everyone's phones are different but so far faux kernal is very stable

read up lul, im using it and it's been good so far

ya the faux kernel is doing really really well
on synergy/bullet i used to get under 4500 antutu score..
now im getting 6458 and im not even overclocking..

I unerstand this isn't what was asked, but I've never had heat issues, using the stock roms cleaned-up by myself after root. The new 2.3.6 is solid as well.

This things plenty fast without overclocking, I'm in no overcompensation contest to get my benchmark scores higher lull

Kernels don't seem to do anything.

Ever since i flashed francos kernel for the first time i failed to see any difference whatsoever in batterylife or performance. 4 versions of franco kernel later and still no change. Even bought his app and tried undervolting. I accidentaly uv'd by 100 in the 700 category and none of the side effects were happening so i tried undervolting all by 200 and even setting on boot. Nothing happened. I then flashed jame bond kernel and nothing happened. When i tried flashing glados kernel it just froze on boot. I experimented with all of them for at least a day and except glados which didn't work they all showed no difference than stock regarding battery life or performance. What could be the cause of this?

Kernels don't have the profound effect you might think on this phone. Not nearly as much as devices I have had in the past.

I'm aware of that, but still. No difference whatsoever? Even when i intentionally try and break it by undervolting by 200?
Sent from my Galaxy Nexus using Tapatalk

What did you undervolt by 200? Some speed steps can get away with that.

What ROM are you using?

Adrynalyne! Its good to see you here!
Yeah, on the Fascinate, Kernels had much more of a profound effect. I can't say the same for this phone. But the OP said that he purposely tried to Bork his phone to see if it worked and it didn't even touch it. That's really strange. I can purposely try to Bork mine and do a pretty damn good job of it.

Some kernels had broken UV interfaces that wouldn't undervolt the kernel and would allow you to undervolt by absurd amounts. (though it wasn't actually doing anything)

Well, are all the most popular kernels broken? Franco, glados, jame bond? I'm more inclined to think the problem is localized (either me or my phone).
And i'm running aokp 20, btw. Had 19 and milestone2 before those, which were all installed after full wipes (before anyone suggests that).
Sent from my Galaxy Nexus using Tapatalk

Your not the only one with this problem as I too have seen no change in battery performance on my gnex. I'm also using aokp 20 and Franco's (14.4). What I don't get however is that my buddy seems to see significant improvement in his phone while running the same rom/kernel combo

I've had some friends do some tests for me and run stock kernels for a while.
The differences in performance and battery life were menial between custom and stock.

What about all those people that claim seeing improved battery life? Not to mention those impresive screenshots of battery stats that show numbers i have yet to even come close to.

Many of those screenshots are sleep time.

naturally. also, data calls are a huge battery drainer, even with excellent reception, when actually using the phone. the same with wifi.
to give the op an example, this last night i forgot wifi on. connected to my home network. the phone slept well (something woke it up in the middle but for a very short period of time, probably gmail), and i only lost 3%. i normally loose 1% in 7hrs approx., so it wasnt so bad.
on the other hand, if screenOn is true, it will obviously drain faster..

Btw adryn, what kernel/rom do you use in your gnex?

Tried a lot of combinations, but at the time of writing the original post i had been using aokp 20 with franco 14.4 for a while. I am currently trying aokp20 with trinity 384mhz gpu.
Also i lost about 2%/hour with franco in standby. I had mobile data connected and autosync only for google account + yahoo mail, all set to sync each hour.
Waiting on trinity now. Curious if i notice any difference besides the lack of franco's blueish tint.

My own or stock. I experiment a lot. Currently I am running a custom with a tweaked deadline scheduler, and a slightly different oc method for gpu and cpu than everyone is using to 1.35ghz. Stock voltages, tweaked ramdisk for filesystem mounts. Stock sleep profile of 350/700 on Interactive. Not using Setcpu to overclock at all. I set the power profile in fw-res to include the extra speed step.
So far so good, but its too early to tell. I went to bed and work up 9 hours off battery with 99% remaining. So its definitely deep sleeping fine I won't know for a couple days on whether it sucks battery dry or not.

I don't play a lot of games but 307mhz to 384, nets me 3fps in Nenamark2. Not exactly mind blowing.

exactly. I used to go crazy doing this and that, disabling this and that to try to get 20+ hours that people were getting on stock battery. Then I came to realize that the screenshots are probably mostly sleep time. Me being a very social person (text, IM, Facebook, and Tweet a lot) there is no way I was ever gonna get anywhere near 20 hours on stock. So I bought a couple of spare batteries, turned stuff back on, turn the screen back on brightly and enjoyed the phone and its great screen without worrying about battery life

Ill be as honest as I can. I just had two nexus and installed two different roms and and two different kernels....I believe they don't do anything as well..And I thinks its placebo effect when people are saying there battery's are better or the screen is smoother....I see not much of a difference even in stock...yes the benchmark may go up but that's means nothing really....

high heat temperature issue on higher than 920Mhz speeds (AOKP+Faux)

Ever since I had my nexus I only flashed AOKP and Faux's kernel. But the annoying part is that when Im using interactive or ondemand and the phone go to a higher speed, the phone gets too hots, and when it reaches 1200Mhz it gets too hot to the fact that I cant touch the top of the screen or the back cover on the camera side. Only way out of it is me using conservative and UC to 920Mhz and the phone wont reach that speed anyway. Any help please?
::No more than whatsapp and Gtalk are installed::
::Heat only happens when the screen is on. when its off it goes into deep sleep without wake ups::
::I have a GSM Nexus with WiFi only on and 2G connected without data::

I dont know how much but it burns! its just way too hot. I had a phone call when it was that hot and when I put the phone on my ear I almost threw it away because of the heat!! My screen brightness is at its lowest but I have the color multiplier from faux kernel on.

Hi,
Temperature is subjective,I mean if you just touch your phone and say "it's hot"...
If I wash my hands with cold water then I take my phone...I find it hot...
Cools your hands (in the fridge ) and use your phone 5 mins, you will find it very hot...
There are already many threads about this...Arrrrgh,can't use the search function ,but for sure for the last week there is about 2 threads about that...
Try a fresh install,starts from scratch with full wipe etc,just your current ROM and if it continues flash another kernel...
Monitor your CPU temp with an app,not just your feeling,it may be biased (System Tuner for example or maybe an app like cpu temp,on the Play Store),for their respective (if you test anothers) kernel try Franco kernel updater or Glados control to monitor the CPU temp.
Also see if there isn't an app,a script,etc...that could fully or almost load your CPU...

Screen gets HOT

I know for a fact the phone gets hot when playing some games like Asphalt 7 and that is understandable but it never used to get hot while in regular use such as browsing the web or text messaging on stock and i could have the screen on for an hour. Ever since i installed CM10 and now on AOKP by task650 I have noticed the bottom half of the phone gets very warm even when doing simple things. I have the brightness set to auto at all times and within 15 minutes or so it starts to get hot.
Does this happen to anyone else or its just me? Also maybe there is a tweak for the screen in the ROM?

How long has it been since you installed these AOSP roms. In my experience, it takes one or two days for everything to settle down after installation, during which the phone might overheat and battery life takes a hit. My advice would be to give it some time, but if you're really worried, try fixing permissions or even going back to a touchwiz ROM.

I am having the same problem with CM10. I have tried multiple nightlies with the stock CM10 kernel and my phone just seems to run warmer. I can't figure it out. When I flash back to the stock ROM it doesn't do it unless like you said, I am playing Asphalt or some other games.

Nah not worried because i have extended warranty on my phone. Its just i like my electronics to function the way they should and when they don't i HAVE to fix them or i will loose my mind, plus its kinda annoying when hold it.
I know it needs a few charge cycles and installed CM earlier this week so its been at least 3 days, but still noticed the phone heating up. I installed AOKP today and will try cycling the battery a few times.
Pardon my ignorance but why would fixing permissions have anything to do with this? Also there is no negative effects to doing this? I don't see any as it wil just mark everything rwx-r--r-- or whatever the default is, but just want to confirm.

I was thinking it maybe the CM kernel, would you mind flashing Kooz kernel? If you have CM for a few days. I still testing AOKP so might be a while before i can flash.

The bottom of mine gets real hot after about 15 minutes of browsing on LTE. It did it right out of the box, and I'm on stock.
Stock ICS on my S3

I disabled LTE yet its still gets hot.

That's what I was thinking it might be and no, I don't mind flashing the other kernel. As a matter of fact, I was wanting to try that myself but I couldn't figure out wich download I needed off the link that you just posted. Wich one should I download and flash with CM10? He's got several flashable kernels posted under the "Downloads" section. I just need to know wich one I need to use with CM10.

Fixing permissions tends to remedy certain glitches on my end. I don't nearly have enough knowledge to tell you why though. However, there are certain aspects of this phone that will lead to heat production no matter what you do: lte chip; powerful dual core CPU, etc. Furthermore, aosp ROMs are not stable nor are they fully optimized for the phone at this point, this will also lead to more resources being spent, which ultimately results in faster heat production. If it really bothers you, stick to what works and flash a stock ROM.

You need to flash one of the AOSP JB kernels since you are on CM10. I can't tell you which one because that depends on which nightly you have installed. I guess there was major code changes after the 14th.

Yeah but it never did that with stock and its not a deal breaker i love AOKP no way am i flashing back to touchwiz. You know the ROM has been so stable that I expected everything to work but your right its not stable yet and some things are probably not optimized and that is the cause for the phone to heat up more then usual or kernel. Guess it can't hurt to make a nandroid and then fix permissions and if it goes south i have a backup:victory:

Yeah, to my understanding, chipsets are designed to withstand a heat threshold of about 60 degrees Celsius. It is extremely hard to get it to that temp at stock speeds, so I wouldn't worry too much about something going awry with your phone.

I've clean flashed the new nightly and task's kernel. My phone still seems to be running warm! I'll run it for about 24 hours or so and see how it does. IDK what the hell it could be. Is there other people running CM10 that are having this same problem? And by the way...Do you know of a fix for the MMS? My pictures that were taken vertically show up in an MMS horizontally and visa versa. Is there no way to fix that?

It seemed a bit better today, but then i been out all day and its been wet and cold so might not have noticed. Its not Task's kernel but rather Kooz but they do work together. Can you also keep an eye on battery life? his kernel is suppose to have amazing battery life and CM/AOKP for me have very bad battery life. Also make sure to cycle the battery at least 3 time.
NOTE: Battery cycling mean charging it to 100% and letting it die to 0% and repeating, this will calibrate the battery and maybe will help.
Just a recommendation for you to give AOKP a try. I always used CM, but CM had some bugs when i tried so i thought might as well give AOKP a try and its actually been solid and has more features then CM. Best part is the build in LED configuration for apps/notifications.
These devs make it so hard to choose, both are very good ROMS.

Yeah. That's a problem I have too. I can't decide which one I want. The KT 747 kernel has seemed to take care of my heat problems. I was cycling the battery anyways. Where can I get the AOKP ROM? Is it posted under original development? The 747 kernel also gave me some much better benchmark scores!
Edit - I see in ktweaker where you can change some voltages but I have NO clue about any of that! Any advice? I think there is a thread on here somewhere about it. I'll have to find it & read it I guess.

Pfft! You should know at this point in the game that benchmarks mean nothing, its all about real world performance. Basically I'd just start playing around its the only way to learn what works and what doesn't on your device! Cause afterall every device is different no 2 chips are the same, what works on one device might not work on another

Sleep Of Death ("SOD")

I haven't seen anyone post about this yet, so I am going to take the plunge. I have a finicky device. Regardless of what kernel I put on, if I overclock at all, I will eventually get an SOD. I have tried Perseus and Core, all flavors, and started various times all the way from clean, Triangle-Away'd stock via Odin...same thing. It is really frustrating. The best results I get seem to be when I don't mess with the voltages at all, but eventually, SOD strikes. Sometimes I can go days. Today, I tried overclocking the new Perseus to 1.8 with stock voltage (after running it vanilla for 2 days with no issues), and within 2 hours, I had an SOD. I am currently on Clean 4.5, but have had the issue in every ROM.
Anyone else have a super-sensitive Note II with kernel overclocking? Anyone else seen SODs at all, under any other conditions?

What are you max screen-off and phone-on speeds clocked to? That could easily be the issue--I leave mine at 500MHz.

Oh man, I am embarrassed to say I don't know...I am using STweaks currently with Perseus, and don't see where to set these values. I know that I was able to use profiles in SetCPU...
Where can I check these values? Appreciate your help!

I switched to SetCPU for now and created a couple of profiles. We'll see what happens.

Can't say that I get the SOD, but if the weather gets TOO cold (which it has for the last few weeks), my phone would reset itself and will be stuck at the "Samsung Galaxy Note II" screen until I pull the battery. Unlike your situation, I'm an extreme underclocker so it's easy to fix my issue (just give it a bit more juice!).

I haven't seen anyone post about this yet, so I am going to take the plunge. I have a finicky device. Regardless of what kernel I put on, if I overclock at all, I will eventually get an SOD. I have tried Perseus and Core, all flavors, and started various times all the way from clean, Triangle-Away'd stock via Odin...same thing. It is really frustrating.

Coming from the Galaxy Nexus (and yes, I did my share of undervolting and overclocking with it) I know some of the dice used in making the cpu/gpu are not the same for every Galaxy Note 2. For example, where you got SOD problems used Perseus and Core, I could flash Perseus and Core on mine and not have the same problems at all. Best thing to do is try a different kernel till you find one that does not give you the SOD. Also, it is better to not flash a different kernel when you flash a new ROM as the kernel that is in the ROM usually works the best with it.

yes sod
I get the sod periodically irritating at times
I kept the phone unrooted and stock for 6 weeks or more, and i got the sod even then
I''ve rooted and have been using scottsroms for several weeks now, and get the sod about the same
I'm now wondering if it is a defective unit?

Anyone getting the sod probably has a bad phone. I would return it to be fixed. I personally never had the sod on any rom I have been on.
