[Q] Reboot ... Clicking? - AT&T Samsung Galaxy S II SGH-I777

ok so let me explain my situation. I rooted my sg2 using zedomaxs method. http://galaxys2root.com/galaxy-s2-root/how-to-root-att-galaxy-s2-sgh-i777/
HTML:
flashed unnamed rom w/ entropys daily driver. now every once in awhile maybe 3 times in an hr it will just reboot and make clicking sounds.... Im overclocked (running 1600 max 200min. Conservative Around 94deg f.) Aand ive flashed a boot animation. No one commented back w/ any problems. http://forum.xda-developers.com/showthread.php?t=1307658&highlight=Boot+animation I have done no other mods. Any one offer any help? Thanks, tom.

Quick way to try fixing is to reflash. If a number of people aren't having problems like that it may have been a small problem during flashing.
A few people, myself included, have heard the clicking every once and awhile. But it's never been tied to causes issues with the phone.

your phone cant handle being overclocked to 1600, hence the reboots. try setting your max to 1400, and the reboots should stop. as for the clicking, i've never heard it before, sorry.

the problem is the same at 1400. if other people with the exact phone as mine can oc to 1600 I should be able to in theory, correct? I would love to find out what this clicking noise is all about... I thought I was imagining things for a moment. Isnt there a command in terminal to show what the phone was running before it crashed?
Thanks for the feedback

There is indeed. Just search about logcats. There's also apps on the market that will do it for you.
You should try running it at 1200. If that's rebooting as well you most likely have system issues.
Not to harp on a point but reflashing would help if that's the case.

[Q] unexplained reboots!

I have to say, the random reboots sucks. I am running Bamf 1.6 remix. I wiped two times, and keep getting reboots every so often. I wish someone could figure out what the heck is going on
Nobody is going to figure out what the heck is going on without any information. What are you doing when it reboots? Overclocked? If it rebooted when u are using the browser make sure you have flash installed.

I did over clock . Over clocking can cause that huh? I did put it back down to 1ghz and have not have any more reboots
Mine runs steady at 1.5ghz. Any higher and I get random reboot.

Each phone is different. Some can handle 1.9ghz oc and others can't handle any. Also undervolting makes a processor less stable as you are running higher speeds with less power.
No, thats not a storm. Its just my Thunderbolt layin down this post.
Are you on the newest Radio? Some people are reporting that the Leaked Radio is causing the problems. I did notice that after I flashed the leaked radio. I started having random reboots.
Leaked Radio.
I for one can second that comment about the leaked radio. I've noticed a lot more reboots since flashing the new radio... especially after the 4G outage last week and changing my phone over to Rev.A. I just turned Rev.A off after the third reboot of the morning... Hopefully that will get rid of some of them. If not, I'll have to flash back. I like the better GPS locks, but they don't do much good when my phone is rebooting itself sitting on my desk.
EDIT: Didn't help. Just rebooted again. Guess I'm going back to the old radio.

Yes it definitely can, hopefully that fixed your problem and bamf 1.6 is a sweet ROM you should really like it.
I have had the new radio since it was released and never had a single reboot so that must not be affecting everybody. Maybe it is another factor causing reboots?

[Q] Why is my phone rebooting at the unlock screen?

OK, so I'm on GSB 3.4 (though this issue began with 3.3), and I'm having a problem with my phone rebooting (screen cuts off after about a second, and the phone immediately reboots to the skateboard screen) at the following times:
1. Whenever I attempt to wake the phone from sleep.
2. Whenever I hang up a phone call.
3. Whenever I get a phone call while the phone is asleep.
4. Whenever I plug the phone in to charge while the phone is asleep (be it a wall socket or PC) [see below].
These problems only occur when the phone is NOT plugged into a charging source; the problem appears to be nonexistent in this scenario. But as soon as I unplug, all 4 become auto-crash scenarios.
I tried going back to GSB 3.2, but no dice. I then resorted to the stock-ish XTRsense ROM, which fixed the issue, but going back to Froyo just was too big a downgrade for me.
Throughout this process, I full-wiped multiple times, hoping to track the issue to an app or setting, but even before restoring anything through TBU (I think I may have just let the phone go to sleep at the "Touch the Android" initial setup screen once), the problem persisted, eliminating apps, settings, or CM7 CPU modifications as possible culprits.
I've continued to play with CM7 CPU settings even up till now, but I'm not getting much of anywhere. I've now resorted to the "Caffeine" app, which just never lets the phone go to sleep, and I just turn the brightness down or activate the "Desk Clock" mode in the default Clock app to save battery.
HELP?
Have you tried Tazz's ROM or CondemnedSoul's ROM, just to see what happens with those? CS's ROM uses ADW as the default launcher (not sure about Tazz's) - perhaps it's something with LauncherPro?

Guys, just thought I throw out the idea that it might an overclocking (i.e., hardware) issue?
I see that the Conap's CFS kernel that GSB 3.4 uses is max clocked at 604 MHz, but maybe that's too high for your particular phone?
I also think that schultzmd's comment about the ondemand governor helping might point to the clock stepping to a higher speed when coming out of sleep (and being related to clock speed). Maybe try running the phone at a lower speed just to see if its better behaved might prove instructive.
Just a thought...
Cheers!

Sounds familiar: http://forum.xda-developers.com/showpost.php?p=14016867&postcount=5186
I'll try the changing the max, but I know I've tried as low as 604 max (19 min) with the problem persisting, and as high as 710 or 768 before GSB 3.3 (when the problem started) with no major issues. And I had already been using Ondemand when the problem started, having stopped using Smartass when I thought it slowing the performance down a bit. Any other governors I should try?
And does the overclocking issue not apply when a phone is charging?

Well, you are introducing some extra heat into the equation while charging, which might be enough to tip the balance against you if it is indeed an overclock issue.

You would have only seen that if you had seen the post in the GSB thread, of course.
I am still going to suggest trying Tazz or Condemned. From what the OP says, he should be able to see that it's having the same issue pretty quickly.
But, just to rule out the OC issue, you could try setting the max to stock 528 and see if it still happens.

I was inquiring as to why the issue DOESN'T happen when I'm charging. I'm not sure if that's what you were saying, but I have no issues while the phone is charging; it's weird, because CM7's CPU governor doesn't allow profiles for "screen-off", "charging", or anything like that. It just seems to make my problem more random and untraceable. It literally is happening on EVERY CPU setting, even 480 max (which to me, is just pointless to actually use)
I've full-wiped so many times in the last few days, I'm wary to just try a different Gingerbread ROM when GSB is (was, for me) so stable and full-featured. I'm trying my darnedest to just stick it out and charge-charge-charge to avoid the issue.
One more thing: if, right after the phone reboots itself, I unlock it before the screen goes off and manually put it to sleep and quickly wake it back up, the issue usually doesn't occur (and I can keep doing this, putting it to sleep and waking it back up again, with no issue). But if I unlock it and let it sit and reach the screen timeout itself (or never unlock it after it reboots, then let it sit for a while), the problem reoccurs.

I have used both GSB and Condemned and you will not be missing anything. I stopped using GSB because I could not get market updates to stick reliably. I do not have that issue at all with Condemned.
Right now the only issue with the latest Condemned is apparently a GPS issue, so I would go with V6 or V7 rather than V8 for now until CondemnedSoul gets an update. Or, if you don't navigate, go ahead with V8. It's just fine.
You're obviously having a stability issue with GSB now, so you have nothing to lose but about 45 minutes of time and a Nandroid Restore to go back to GSB if you don't like it.
So, I had a minor issue that was fixed by switching to a different ROM. It's worth a try.
I wish you luck finding a solution.

Nate,
Sorry about that ...I was confused from where you asked in post #8 about whether or not overclocking was in effect while charging (it can/could be, depending on the overclocking monitor/govenor I suppose) and I had lost that point from your original post.
I would say take doogald's advice and switch to at least some other ROM since that would help indicate if it is indeed a software issue or a hardware issue. Its sounding like its not clock-speed related given the things you've already tried. If you've still got issues on other ROMs, that would tend to point to some hardware issue (our Erii are getting a little long in the tooth at this point, after all).
You could even flash back to stock and see if the phone is still stable there since you can always re-root and re-restore your Nandroid backups.
Good luck...I hope you figure something out.
Problem is alive and well on Condemned GB. *sigh*
XTRsense was fine and flawless, but going back to Froyo after months on gingerbread was just too depressing for me...

I'm going to make one more suggestion - not sure if you have tried this yet, but try flashing GSB from a full wipe. When you go through the setup, DO NOT LOG IN TO YOUR GOOGLE ACCOUNT. After the launcher starts, go into the market, let it log you in to your Google account then, and then install all of your apps and change all of your settings from scratch.
When you log in with your Google account when installing a CM ROM, it tries to restore your apps and settings from your last CM ROM install. It may be that you have some weird setting or app that is causing this that you just keep reinstalling when you flash the ROM and log in with your account.
If you've already tried this, then try running xtrSENSE or xtrROM instead. They are both excellent ROMs and clearly your phone likes them better.
[edit] Oh, and try leaving your min at 245 MHz for a while. See if that helps your phone run better. It should, and it should have the exact same battery life as 19.2, as nonsensical as that sounds.
It is literally happening as soon as I boot the phone after a fresh GB install. I four-corner the Android setup screen, let the screen time out, and boom I'm screwed.

Phone random reboot. Troubleshooting help request.

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

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.

Phone Randomly Shuts Off

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.

9x out of 10 random reboots are from either undervolting too low or overclocking too high.

[Q] lulzactive cpu problem

I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?
Just try clearing app data rebooting and reinstalling the app. That problem has happened to me every once in a blue moon and that fixed it for me.
Sent from my SGH-I777 using Tapatalk 2
Thanks, I'll try reinstalling the kernel.
Which app are you referring to? because I had this problem no matter which app I used to change the governor (Extweaks, voltage control, setcpu).

Wipe cache, wipe dalvik. I've read more problems with the cleaning script than good.

Lol what exactly have u heard? If it was causing problems it would get pulled. The only thing I can foresee happening is someone flashing it and then not flashing a kernel or something. Which would be user error.

CPU related as well...
Hi Guys,
My first post here. I am total noob. I rooted and installed the newest ShoStock2 on my at&t galaxy s2. Everything works perfectly. I couldn't be happier. I also went bought the setCPU for overclocking it. That too seem to be working fine.
My question is. I didn't set up any voltage requirements. The only thing I did was to set it to 1600 MHZ and 200 min and change the governor on the bottom to Lulzcrative. Will this work? Do I need to actually do something with the voltage? am I really on 1600 right now? I cannot tell.
I ran a quad test (I now it is meaningless in real world) it came 2818 yesterday. I ran it again this morning ..... It froze and took my battery from 45 to 9 in less than 3 mins!!!!!! The phone got really hot. I took out the battery right of way. The battery life showed 23 percent this time.
I got little afraid of the quadrant testing ... The phone seems to run good without that but I am not sure if it is set up how it is suppose to.
Could someone help me out please? I tried reading the forums and that is where I got the idea in the first place to overclock it.
So to summarize it, I guess phone is fine right now but I am not sure if I set up setcpu out properly.
I am on the newest shostock2. I have galaxy s2 on att. I am pretty good with computers and phones but not sure about voltage and other problems with relating to setCPU.
Thank you advance for helping me out.

Lots of questions there. Phone overclocking is the same and at the same time different than PC overclocking. I too bought SetCPU and due to bugs and problems have completely abandoned it. Honestly with the exception of running an epeen benchmark there is little incentive to overclock. Find a newer Kernel (I use NEAK which has no overclocking ability) and install it, performance is stellar. You really have to ask yourself, is my phone slow enough that I need more CPU power to make it faster?
To see what time your CPU is spending at a given clock speed, download CPUSpyhttps://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&feature=nav_result#?t=W251bGwsMSwyLDNd, you will be surprised to see your phone spend very little time at it's max clockspeed.
Due to the immaturity of the fab process for our CPU's (well SoC), what is a stable overclock for one person might not even load for another. These CPU's are not like an Intel Sandy Bridge, with 1Ghz of free overclocking, nearly guaranteed. You can certainly play with voltages to try and attain a higher overclock, but at the expense of CPU lifetime, as well as battery.
Additionally, it takes a new Kernel 3 or so full charge, discharge cycles on a phone to really 'settle in' and 'learn' a particular phones battery, while yours got hot, which to me indicates an endless loop of some kind running in the background.
My advice would be as follows: Choose a ROM you like, feel free to play with different Kernels, again, I use NEAK, which does not work for some folks, or crashes or whatever. Give it several days to 'settle in' and if your still not happy with performance or have stability problems, try a different governor/scheduler. You really need to establish a good, solid baseline of your phones performance and make small changes and give them long enough to establish any changes to your phones overall stability. Basically running cowboy through your phone and making changes will have a negative overall outcome. Make small, documented changes, test and see what overall effect this has to your phone's stability and battery life, and make another change.

I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?

Lulz has known problem in 3.2b2-1
Gokhan has fixed it in 3.2b2 - 2
Wait for ktoonsez to update it for us

Thank you so much for the information. Could I simply uninstall the setcpu and go back to normal? Simply reflash the rom and/or kernel? I really like shostock2 with the cherry picker kernel for now. I want to give them a week of try to make my mind. Before the setcpu I think.I was better off
Thanks for the help by the way. I appreciate it.
Thanks for the update about the new siyah kernel. Glad it wasn't just me with the issue. I was going to post this question in the siyah thread but am new to the site so didn't have permission so thanks for finding me all the way over here

I'm just going off what I've seen in the Siyah/NEAK threads. Most of the lock-ups/random reboots I've heard people having had used the cleaning script. Either that or its just coincidence.
I may be wrong but I think that using the kernel cleaning script actually solved most of the lockups. Perhaps I misunderstood the threads.

Hmm, well I've just manually wiped cache and dalvik and have never had problems between roms/kernels.
