The past two days my phone has been randomly rebooting. It has happened twice in two days. I have no idea how to pull any information from my phone to possibly see what is happening. I am moderatly tech savvy so with good directions I can do just about anything. If anyone is willing to help that would be great.
Phone: At&t GSII (obviously)
Rom: Cognition beta-4
Kernel: Entropy's doom v2
I am using set CPU with profiles. Not over clocking or undervolting, I just use it to underclock when phone gets to hot or battery gets to low.
Anything else you need to know or want me to do please let me know. Thanks.

Complete reboot back to Samsung screen? Or back to bootanimation?
If all the way back to the Samsung screen, there isn't much you an do right now other than wait - I'll be putting an update out tonight, and one of the main features is that I finally got ramconsole working. Ramconsole is how /proc/last_kmsg (the last things a kernel printed before a reboot or crash) is implemented. Once I release my next kernel, if you flash it and another reboot back to the Samsung screen happens, the following will give valuable debug information if executed from Android Terminal Emulator or a similar app:
Code:
cat /proc/last_kmsg > /sdcard/last_kmsg.txt
Then zip up last_kmsg.txt and post it - but as I said, you'll need to wait for the next kernel release before you can do this.
I haven't seen it reboot but it asks what launcher to use (because I didn't set a default) and the battery useage is reset. It will say it has been unplugged for 20 min while it has been for a few hours. Those factors make me think it does a full reboot.
Don't know if that helps. If there is anything else let me know aside from that I will flash the new kernel when its out. Thanks for all the great work

Very simple fix:
Uninstall SetCPU and reboot the phone and magically it will
no longer randomly reboot.
(you can always re-install it if you don't mind random reboots )
Good Luck!
You think it's set CPU even though I'm not over clocking?

How long do you actually think that it takes to simply uninstall
and reboot your phone to see for yourself?
Even if you don't over-clock whatever you do with it can cause
the rebooting problem you are describing.
I certainly am not going to test it for you since I never over-clock
or under-clock anything including my phone and computer.
If the phone was meant to run a lot faster or slower than the
the manufacturers would be advertising the phones with faster
specifications so they can sell more of them.
It's only makes good advertising sense.
Think of it this way, lets say you buy a new car and decided to put
jet fuel into the gas tank to make it have more horsepower so it can
run lot faster than it was designed for, do you think doing this will
make the car more or less reliable in the short or long term?

You claim SetCPU is the problem, where is your evidence?
I test my kernels using SetCPU, I have never had a problem.
I keep hearing anecdotes about SetCPU causing problems for people, but there is no way it can possibly cause stability issues. sysfs is sysfs, and that's that.
The only place where SetCPU might cause a problem is with screen-off profiles less than 800 MHz on kernels that don't have the SoD patch.
To the OP - Sorry I didn't release tonight, I got caught up in trying to help someone track down a power management issue with wifi. I'll do it when I wake up.
I am not stupid and the reason I was questioning was because I have OC/UC/UV before and I know what the stability issues are like with them. It is not something that happens frequently so it is hard to test. I have been going now for over 24 hours and no reboot. No changes to set CPU either. Primarily though I wanted a concise way to pull info so I can help people like entropy.
(Off topic a little) Manufactures might UC hardware for a few reasons. Battery capacity and heat are usually two of the big ones. If you stuck your phone in the freezer you could probably OC this phone to 2ghz and run stable. I OC to 1600 for fun and its completely stable. I clock it down if I'm out and it is hot or I am in the sun.
To entropy: its cool I check the forums every hour if not more frequently LOL. I think it has become an addiction. Once the kernel is out let me know what I can do to help.

Same as the previous releases, which do.
My first time posting here, so please be gentle.
I've had my SGS2 for around 6 months now, its an unlocked ASIA (as I live in BKK). I noticed on the original stock firmware that the phone was running hot, as in the back panel around the camera would heat up to the point I could feel it in my pocket. This would normally happen if I was using a game like angry birds, or a psx emulator. But sometimes it would happen in the browser under normal conditions. I just thought this may be a issue with dual core phones, so I took this as a 'feature' and accepted it.
But now lots of people I work with have this phone, and it came up in conversation about heat. Everyone stated they do not have this issue, that the phone remains cool all the time.
I have moved between many different ROMs, and have finally stuck with Westcrips ICS ROM. Then a strange thing happened, the heat issue goes away with version 8.4. Phone is cool all the time, even playing my PSX emulator in software mode. Battery also increased from 12 hours to 16-18 hours.
But now I just moved up to 9.3, and its back again, the front screen is very hot to touch when using things like the MX video player, or surfin the web. And if I launch a game ... well, forget about it. The battery drain is immense to, be lucky if I pull an hour of use like that.
Anyone else suffer from this? Hardware fault? I can't take it back because my flash counter is probably in the 20's now, and I can't find a reset JIG in Bangkok.
Cheers.
FYI, I always do a clean wipe, dalvik / cache / permissions.
same issued here, phone bought from Thailand also. Phone getting hot when browser,downloading and playing some games( not all). And its really hot
Changing Rom and kernel sometimes solved it for awhile but eventually will come back.
Looking for solution also
Thanks
P/s: right now im using LA4 stock Rom and CF root LA4 kernel and still get hot

Thanks for getting back to me.
The one I know that fixes it is Resurrection 8.4. Its a dam good rom, and given me the best battery life (once I got 20 hours with normal use). But there is an issue with touch screen sensitivity that makes it annoying.
Maybe its something to do with the Kernel on the Asian models?
If I find a fix I'll pm you.
Hmmm mine only gets uncomfortably hot when playing some 3d games. Didn't experience the same level of heat when just browsing though... It just gets a little warm but far from gaming temps.
What i did was undervolt and underclock when playing. It did reduce the heat and extend the battery though i admit it's not the best solution / workaround.

I use Tegrak Overclock so I can mess with clocks and voltages with the stock kernel. See below for my settings... 100% stable on my phone.

Well it looks like the ICS kernel is not supported right now under Tegrak. It is bleeding edge.
I tried setCPU to under clock but ended up with a lot of slow down and some full system freezes.
Guess its back to 8.4 until I find a more definitive answer.

Since you're using Westcrip's Resurrection Remix, you can get rid of the triangle by using Chainfire's TriangleAway app - I'm using Resurrection too and it got rid of the flash counter and the triangle.
TriangleAway should work on all ICS roms though.
Strange, installed triangle away yesterday evening. Work like a charm, so I guess if I need to return I can now.

I'm starting to have some serious issues lately, now I can't even boot my phone up without it freezing up at the samsung s animation. I have tried to odin back to stock eh03 and it passes and I goto boot up for the first time and it keeps getting stuck either at the animation or the verizon animation. I have odin the stock froyo and all the same thing happens. Is it time to try heimdall? I wasn't having any issues last week when I would odin back to stock and I have to admit I have been flashing like crazy lately because I kept freezing up and rebooting for no reason on every rom I have tried even on stock froyo, gb, ics, tsm, superclean it has been getting terrible lately.
Thanks
when you odin back to stock are you checking repartition and using the atlas pitfile?
yup and ive tried a new sd card, buddy told me to try it. Could it be the cable? But odin does say it passes. I have odined in the past with the same pit and eho3 and didn't have any problems now I just cannot get it to work for whatever reason.
Just got it to boot but freezes up when its running media scanner? Any ideas?
Sounds like it could be an issue with your SD card?
Are you running the phone in an uncommonly warm environment? Put it in the freezer for 2 minutes and try to let it boot in there to see if it's a heat issue

i think you might be on to something, i was able to boot it up before i put it in the freezer and the it ran perfect in there, but it doesn't feel like it is heating up that much, i only really use it inside and really light use. i've had it freeze up in recovery before or when i unlock the phone, im not doing any heavy use at all its just really unstable.
You might unfortunately have a dying phone... Have you tried to tweak voltages at all or use a program that will clock down the processor when a heat threshhold is reached? That might be able to eek out some additional life from it.

What is the temp where these phones start locking up? To answer your question no I haven't touched any voltages at all. I have noticed too when I start charging is when it gets hot pretty quick and will start rebooting
Sent from my SCH-I500 using Tapatalk
Each SoC is different, but you shouldn't get lockups due to heat from light or normal use. I've had devices get uncomfortably warm without lockups or reboots. Could the phone have gotten damaged somehow or have you overclocked it?
I have dropped it before and its got a small crack and yes I have oc'd it before but never more then 1200mhz as I can recall. Do you think this could be more of a hardware issue?
It certainly sounds like a HW issue if you have already used Odin.
My suggestions would be to use an mtd build as they run lighter and the media scanner isn't quite as intrusive. Use a custom kernel that allow you to tweak voltages to see if maybe some different values are more agreeable to your SoC (this can also be accomplished on bml ROMS). Also, monitor your hardware and see where it starts to have issues with temperature.
I was able to boot up cm7.2. As long as its cold I have no problems with it. This morning I tried to boot it up at room temp and it froze when I unlocked it so I will try to flash a kernel on it and see what happens
What it really sounds like to me is a loose connection. If you don't feel heat from it. But it boots at very cold temps, than maybe the cold is contracting a soldered joint just enough to prevent the phone from dieing. Think of the xbox 360's red ring of death. first it acts funny, sometimes getting lines on the screen and freezing, then eventually red ring of death! The cause in the xbox is the motherboards were soldered in England under a "rohs" compliance. Which means lead free solder. Over time heating and cooling of the solder would crack it and give the red ring of death.
So, I'm not certain. But it sounds like the same thing.

That would not cause this. But you flash it with Odin. You can find one somewhere in the forums.it's highly recommended you have them when using ics roms

I've only had this happen a few times and was wondering if anyone had this happen to them also. I'm rooted and run custom roms, it doesn't seem to be rom or kernel dependent.
For example, I had my phone on since noon and haven't really used it since then except a few times to check the time. I just pulled my phone out of my pocket and hit the power button... nothing. I held it down and it started to boot up. When this happens the battery is never dead (it was at 68% with the ext. battery this time), it just wants to turn itself off. It seems to happen when the phone is "sleeping", it's never done it when I'm actively using the phone so it's not an overheating issue.
It's not really annoying since it doesn't happen often, it just confuses me.

still you might want to check the rom and kernel just in case, either re-flash or change.
if the problem still happens, use your warranty and get a new phone.
what rom, kernel, and recovery are you using?
I actually just happened earlier again. Got a text from a friend that she was here, so I went down and let her in, came back up and went to check my phone a few minutes later and it was off. WTF.
I'm currently using Nils newest business sense with the OC'd ICS kernel and the latest Amon Ra recovery. This used to happen on GB also so it's not a rom/kernel problem IMO.
It happens so sporadically (except for tonight apparently) that it's maybe happened 5 times since I got it on release day.
Maybe I have the governor in cpu master set too low? I have it at the lowest of 384 MHz, I've always wondered this: whats the difference between conservative and powersave?
did it happen while you were on stock GB or on a custom rom and kernel? maybe try relocking and running stock for a while and see what happens?
I honestly don't remember, it's been too long lol. It's not worth it to go back to stock and relock considering I like ICS too much.

that's the issue right there, run the stock kernel at stock speeds.
How could it be the ICS kernel when it's happened on GB also?
Which OC? I've read that the 1.8 causes random stuff like this, but 1.7 doesn't.

Not all phones can handle overclocking.
Mine is stable about 98% of the time, it may actually be the extended battery that is causing the issue.

9x out of 10 random reboots are from either undervolting too low or overclocking too high.
I went back to the stock kernel since it seemed to be a little choppy with the oc'd kernel. That may have been the problem after all.

Dear Family,
i have a problem with my galaxy SII since i got the phone tell now
i've got this handheld 6 month back and its now rooted having ICS AOKP RR 2.2 with CM kernel remix
and the device is getting overheated in the part of the camera , the overheat is happening when ever am browsing the net on WIFI or even 3G
i searched the internet regarding the same and i got that the issue is in the base-band so i flashed KH3 and nothing was changed
i flashed my device with amout 300 ROM (official/unofficial) and nothing change in this issue
also i found that my device sometimes is stucked on 1200 MHz for about 5 MINS without a valid reason in the foreground

Mine heats up too, if you think about how much stuff is crammed into such a thin, light phone it's no wonder it gets hot

300 ROM??? Hmmm... Anyway I m also having(probably Had ) the heating issue... First Kernel-Siyah 3.2.x was heating while talking in call also.. Used to heat up like anything. Now on Fluxi heat reduced but not completely.. Today I called my frend to McD to check his SGS2 phone.. His phone is purely stock and was runnning ICS official 4.0.3.. For normal use the phone dint heat, neither mine.. Now the heat game started when I watched a Video(Not HD) even in mine also But gud thing was mine was not as heated as his may be because of Kernel or anything I dunno.. The main thing s battery shouldn get heated too much... But I dunno many ppl not having heating issue... S2 s so thin that heat has too dissipate thru somewhere so it uses the camera region... Try using the phone with low brightness it might be helpful also try KI4(correct me if i m wrong!!) modem. I din try that modem yet...

Try pulling the battery for 5 minutes to let it cool, then replace it. You can also try under clocking to 800 /1000 mhz to save some battery and not let it go to 1200mhz

* the battery's Temp is about 35 C
* i remember that 2.3.5 was the only version that i have which is not having this issue.
* it seems that everyone tried something and it worked for him but everybody's something is not working with me.

i flashed the modem KH3 and nothing happens i did down clocking the processor and nothing happens
This phone is stupid sometimes. Just sat in my pocket for the last hour doing nothing.wifi off
The battery drops from 89% to 65%
I take the phone out and its super hot
Says 49 degrees which isnt dangerous but it is very noticable in the pocket and to hold. and the chart says the phone was awake through that whole time without the screen on.
As soon as I start using the phone again it starts to cool down.
Bit annoying how often this happens.
i never had this issue on gingerbread
is there a fix for it?
Install BetterBatteryStats and check which program causes the wakelock. While ago Google Chrome was known to create this issue.
