Random shut down?

My Galaxy Nexus randomly shuts down and doesn't turn back on untill I turn it on manually. It will do this at the most random times even when the battery will be full. I have also noticed that my phone seems to heat up a lot as well. Could this contribute to the problem? The details of my Galaxy Nexus are: Verizon Galaxy Nexus, 4.0.4, rooted running: AOKP Build 39, franco.Kernel nightly r-194 clocked at 1.3GHz. Thank you in advance

the cpu autmagically shuts down at 110C. if you have thermal throttling off, it can easily reach that point if using heavily.

most likely the overclock isnt working well for you and is making it too hot

hmm yeah my phone does get around 100C+ alot... how can i check if i have thermal throttling off? and yeah i think the temp is causing this...what should i do

since you are using franco kernel, franco kernel app can enable/disable thermal throttling. it has a cpu temperature meter too. many kernels support this feature. trinity kernel, and trinity kernel toolbox can also disable/enable thermal throttling and has a cpu temperature widget. if you do have thermal throttling off, turn it on. that way when it reaches the throttle limit, itll slow down your cpu and cool off. the cpu cools off rather quickly too.

for franco kernel maybe, but id assume not just to be safe. if Francisco and Morfic implemented that option the same way then the TKT app would work. im pretty sure that i read that Francisco added the option to his franco kernel updater app. but i dont use franco kernel so im not 100%.

there is probably a terminal command, but i do not know it. everything in these kernel control apps can be done without the app, but through the terminal emulator.

One X keeps overheating

Hi!
It's the summer where I live and it's like above 40°C in my appartment (Yeah, I've a free sauna, jealous?), and this cause my One X to overheat all the time, I'm not even doing "heavy" stuff, just browsing the Internet or Facebook via Wifi, I already tried to slow down the CPU to 1200Mhz but it is still very hot, is there a solution to avoid this issue (apart from "DON'T TOUCH IT!"), I can't believe that Taiwan is a cold country and that the HTC was not made to work at 40°C...
You can see my ROM and Kernel above this message (signature) I'm trying to install Viper ROM to see if it fixes the issue... :fingers-crossed:

Nevermind, I fixed it, I used wrong voltage and too low down threshold value in SetCPU which caused the CPU to overheat and stand longer activated, silly me

he fixed nothing, he messed up his cpu settings and noticed it later, so he put the cpu settings back to stock.

Wow, what a up !
Seriously though, I'm not using my HTC One X anymore, but last time I used it, I used Faux kernel with -100 uV and some Ondemand governor tweaks (mostly to lower frequencies at as state that is just above lags) and it was running lagfree and a lot cooler than stock, but I hope you don't mind loosing a bit of 3D perf...

[Q] Core and frequency control according to temperature

My N2 makes me crazy when it gets warm.
When it reaches about 36 celsius degrees it starts with frequency limit of 800MHz.
The second step is making 2 cores offline and at last my gadget becomes limited to 2 cores at a max. of 500MHz.
It becomes almost unusable for me when in car. I use two navis in multiwindow (Waze and Sygic) and AutoGuard recording in background with FullHD and in about 5 minutes it's restricted hardly.
I know it's for safety reasons but I think it's too strict.
Is there a possibility to raise the thresholds of these by a few degrees?
What kernels support this?
There is a nice app called Android Tuner which is able to set these tresholds but it is for Qualcomm CPU-s only...
Thanks for any answers in advance!

Not exactly understand...
There must be a safe setting for it as with Perseus kernel the thresholds are higher, but not too much. I forgot to edit my question according my experiences with Perseus.
At least with Perseus I get a max of 1000MHz at most cases but it is not enough for me cause I use apps needing high resources.
Would You be so kind to write about the value to be changed in order to get higher thresholds?

If I understand you correctly. Then you could try trickster mod.
Or try saber kernel. I use this baked into the Jedi rom.

Thank You for the advice!
Now I had some time so I'm on Saber kernel and just testing.
The testing is awesome till now: the phone is working more powerful with this kernel and doesn't get hot so soon. :good:
Oh, now there is something strange, the programs get FC-s...
The phone is on charger, I ran AutoGuard in the background in FullHD, Sygic and Waze in MultiWindow, VideoPlayer in popup with a FullHD video and SuperPlayer in popup with another FullHD video. It was extremely fine but after a few minutes the players collapsed and AutoGuard had an error. The system is stable anyway. It seems I have to restart phone now...
Edit: After restart I got an old problem back: Dropbox is unable to run again... I loved Perseus because of this, on Perseus this problem was away... I hope that I won't get the other issue back with my WiFi... And it seems, AutoGuard became stupid too... :crying:
I don't give up and keep on trying to make them ok.
But I can't find the thermal control feature in Trickster Mod Donation altough I have just a minute for it.
I am reading Trickster webpage to get ahead...
Question: Are You using Jedi ROM and have no thermal problems?
In that case I'm going to try that ROM, cause I'm on hunting for a ROM that works with no problems for me.
I tried some lately and till now Omega v18 was the best amongst them. I tried MIUI, ProBam, Hawkish in the last days and I get problems with all of them or had non-working applications and/or features which ones are essentials for me...
Edit: mmmmmmmm, as see there is no Jedi ROM for international N7100...

hey bro,
wow you seem to be a bit more advanced than me so maybe ive reached the limit of the advice i can give you.
However, if you inform me how to check for thermal problems i will surely do that and then report back.
the saber kernel to the best of my knowledge is underclocked so if you try to o/c it maybe that will prevent your fc's. I have read in the various threads, of which the community is very helpful, of some issues for heavy users due to the u/c.
Regarding the jedi rom i am a uk 7105 user and to the best of my knowledge i thought it would also work for international 7100 users?!?!
Here is the thread i use.
http://forum.xda-developers.com/showthread.php?t=1987634
reading the op of that thread it would appear you are correct. I do know they are working on version 18 so maybe that will work for you. fingers crossed.

Thank You for Your effort!
I'll keep on investigating for a solution.
Unfortunately the real test was horrible with Saber kernel, when I tested it in car the temperature got high soon and the thersholds were low again.
But it's a good idea to try o/c thank You very much!
I'll try it tomorrow, now I have to go to play Cod4... :laugh:
And I found that TWRP is recommended for Saber and a few minutes untouching after the restart so I'll try again.
Have a nice day!

you too bro, sorry i couldnt help more.
but if you post in the saber kernel thread there are some helpful and intelligent folks in there that may have a better solution for you.

Thank You again!
I got some experiences with the newest Saber kernel and I like it 'cause the first kernel I can use 100MHz step with and using 300MHz step too.
It seemes to be good at battery consumption too. My only problem that this kernel doesn't support STweaks so I can't regulate charging voltages like I used to. Perhaps only Perseus kernel makes it possible as I can't get any other programs for it till now. Or NEAK kernel and the new versions of AGNi pureSTOCK kernel as I read their pages. I'll try them some day. But Perseus is my favourite.
I think it's important to say that the kernel isn't UC/OC by default so this doesn't make any problems and it's not UV-ed too.
I set min. to 100MHz and max. to 1920MHz to test and it's stable till now. I tried to Overvolt slightly and had no change on media programs behavior they don't like each other as I see.
Trickster Mod is nice 'cause it shows the CPU temperature which was helpful to understand this regulations of thermal control are needed.
When I tested it turned out that CPU is below 70 degrees while the battery temparuture is 'only' about 40 degrees.
So thanks for Your kind advises!

wow. Ok i think i understood most of your post. probably a little bit over my head but i need to learn.
I really like the new kernel im getting 1% battery drain an hour with the screen off which truly is unheard of for me,
The kernel runs real smooth apart from when i play asphalt 8. Or i should say it runs smooth playing the game until the phone tries to do something else. For example if it attempts to update a programme or if a message/email comes through. then the game just lags and i have to wait for the phone to stop multi tasking before the car starts to move normally again.
So im surprised to read you say the kernel isn't uc/uv by default??? I was pretty positive it was. But i dont know for sure and im probably not clever enough to figure it out lol.
I wonder what settings i would need to increase to aid the phone in its multi tasking? Also there must be some kind of programme we could use that would test our specific phone/cpu and tell us which settings it would prefer. As i believe each phone will run slightly different?
You are right i remember reading the kernel does not work with stweaks.
I wish i could work with you and figure out how to optimise our settings but i simply dont have the skill set.
I presume you used trickster to overvolt slightly?

No, I didn't overvolt at last. But once I tried and didn't helped on my problems.
Unfortunately now I'm back on Perseus kernel again 'cause some issues with Saber. It became crazy every time and locked my CPU on 160MHz only and only reboot helped.
The other issue was the stuck system server process what was active all night and didn't stop hard work.
Now I'm on reading the kernel's page till I get cleverer on it... then I perhaps try it again 'cause I liked it.

[Q] GNex Reboots when running certain apps

I'm currently running PA 3.6 and the AK Diamond kernel. 99% of the time, everything works fine, however when I start running Puzzle & Dragons, the phone gets really hot and more often than not will reboot before I finish playing. I have also tried using the AK Kubo (stable) kernel, and it does the same. I'm kind of a noob so I don't tweak the kernel settings very much, and I don't really know how to go about fixing this. One thing to note is that on the stock PA 3.6 kernel the phone still gets really hot but it won't reboot. I'd like to keep using the AK kernel as it makes my phone run really smoothly but I would also like to try and fix this problem.

The sole common point to that whole story is Puzzle and Dragons.

Are you saying that AK kernel and P&D just don't get along? Because although it gets hot, on PA 3.6 with its stock kernel it won't forcibly reboot my phone like it does with AK. I've found a temporary workaround which is to switch the governor to powersave while playing...but that doesn't really fix the issue...

there's this thing called quality of the components used; the chinese can make the best and the worst.
every chip handles the tasks that are required of them yes, but that's why you see devices that can OC to 1.6, 1.7 even 1.8ghz stable, or UV like a boss, and others that can't handle even 1.6ghz oc or huge UVs.
for example, mine can UV like a boss, but not so good at OC'ing.
thermal throttling of the cpu might be more agressive with some kernels.

Question. Why does my s4 keep overlooking itself?

I have a S4 mini running custom carbon kk unofficial 4.4.3 as it comes with the settings to set CPU's and governors but the phone keeps changing the min to around 1400 but the max stays at 1700.i don't notice until my battery is draining really fast or gets hot. anyone kno a fix to this?

Which governor is it using to set a min of 1400? Ever likely it gets hot and eats power! I use f4k's kernel, and the 'Performance Control' app to look at and alter stuff - you don't say what you use or have tried.
There is a Carbon 4.4.4 available with f4ktion 1.5 kernel - might be an idea to flash that and the problem might go away!

It's on every governor this happens but I use Wheatley. I would manually set it to around the 300s but in a couple of hours it would auto set at 1400 on its on. This causes my battery to drain my kernel version is 3.4.91 f4ktion 1.4.5 eur lte

Strangely enough I've settled with Wheatley too! but it spends most of its time at 162 when not in deep sleep (a bit like me!). This really needs posting in the Carbon thread so I would post a few more things here to help or comment on stuff to get to 10 posts and then ask in there. I can't think what could be causing that behaviour, if it was me it would be bye bye 4.4.3 and hello 4.4.4

Does the actual minimum change rather than it simply running continually at 1400+ and if so which governor does it change to if any!
I read somewhere in the Carbon thread someone was having similar problems so they flashed the kernel twice, one directly after the other; seems something wasn't getting written correctly the first time but was the second, and the problem went away. Worth a go...

I found this : Q: CPU/GPU frequency doesn't stick?
A: If your frequency settings don’t stick, it's because on certain Qualcomm or JB and higher devices, there are certain system services (thermald/mpdecision/project butter) or kernel feature that rewrite frequency settings based on current thermal status and/or touch input. Certain custom kernels for your device should include work around for these issues.
Is this a fix?

It could help. Trickster is good. However, this suggests that there is something else causing or forcing the frequency setting to be changed. The question is what? and I've no idea:crying:
