Phone random reboot. Troubleshooting help request. - AT&T Samsung Galaxy S II SGH-I777

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.

[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.

How about on Tazz or Condemned? And, 19.2 is too slow for a minimum for this kernel. 245 should be the minimum.

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.

Undervolting with SetCPU on Atrix

In my neverending attempt to extend my battery life, I installed SetCPU. The underclocking with profiles has extended my battery some, but Id like more.
I know very little about undervolting, its a new concept to me. Could someone elaborate on it, and may've suggest voltages for each speed setting? I hear it can do wonders for battery life.
Sent from my MB860 using XDA App
just experiment, start with small increments (don't save your settings!!!) see if it reboots, if its stable for a day or two, increase it, when it starts crashing dial it back a notch.
Just like overclocking except in reverse and with voltage basically.
note I'm not sure re: kernel requirements, I haven't tried it yet with my atrix, and my current ROM runs stock kernel I think.
its hit and miss, for example on my SGTab I can't undervolt at all or else it crashes all the time, others get away with -100mAh across the board (bastards), but mine is happy on 1.1OC.

Sent from my MB860 using XDA App
Yes, start conservative.
Another way to use setcpu to improve your battery life is to set a screen off profile to restrict the CPU speed to minimum when the screen is off.
I tried that one, but it kept stalling my phone when turning the screen back on when it was at the bare minimum.
EDIT: For anyone wondering, -75 seems to cause frequent freezes.

Think of it as tweaking the CPU of a phone to use just enough power to prevent it from failing in order to conserve battery life without affecting it's normal operation.

Any overclocking or underclocking is always trial and error. Rule of thumb is to only ever change one thing at a time in small increments, then test before adjusting again. Your approach should be methodical and not haphazard, i.e. in a PC change cpu clock speed in small increments until you fail to boot or BSOD, then change voltage in small increments until you boot and are stable again. Monitor temperatures all the time, and add cooling if necessary. If you take a methodical approach, and don't rush things, you can achieve surprising results with hardware/software tweaking.
What would be a good way to test once I increment a voltage?
Sent from my MB860 using XDA App
A good test is to just use it as you normally would. If the phone doesn't reboot, you're good to go.

So, I had checked off set at boot on the voltage screen. Unfortunately, this has rendered my phone to continually reboot and freeze, as one voltage is too low.
I do have a nandroid backup from right before installing SetCPU, and backups of working voltages, but I can't get the working ones restored before SetCPU starts and freezes my phone.
Is there a way I can default or disable the SetCPU settings without having to reflash the ROM or a backup of it?

Do something CPU intensive also to see if it crashes, like play a game. You want to stretch the phone to the limits to test it at the most extreme condition you will use it under.

Maybe a factory/data wipe?
Other than that I can't think of anything myself.
ddddddddddddd
you may try to use default stock kernel, on wich overcloking do not work.
re: setcpu, sorry I think you have to reflash... thats why you don't save the settings until you're sure
there is no shortcut way.... you may be fine for a day but next day it keeps crashing. Happened to me on my SG tab when I went to 1.2 for example, I thought it was hunky dory then a few days later crashing galore.
the longer you leave it for the better you are, its really your call to make. Some people prefer the extra speed and will live with a crash or two a week (not me, its my phone not gaming pc lol).
not sure how much stress testing you can/should do. Back when I was OCing PCs I would leave stress tests running overnight, but probably not a good idea to 100% CPU a phone overnight lol

[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.

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).

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)?

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

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.

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.

How to diagnose cause of extreme UI lag?

What I'm running:
Latest NEAK kernel + AOKP build 36.
Issue also occurred in Phonebricker + NEAK (sammy version).
My issue:
Occasionally the OS will get extremely slow, like you would expect if the phone were running at 100mhz or something. Everything continues to work, just reeaaallly slow. For instance, music playback gets very electronic-y as sounds are stretched out, tapping one of the capacitive buttons takes 5-10 seconds before vibration/feedback, and another 5-10 seconds before a menu pops up. I managed to get the NEAK configurator open and scrolled to the CPU tab, and it claimed I was at 1200mhz - though the phone didn't even get warm so I'm skeptical.
I'm guessing since I've done a full wipe between phone bricker + NEAK and AOKP + NEAK, the only thing in common are my apps and the NEAK kernel, so it stands to reason it would be one or the other causing this. My wife's GS2 is running AOKP + NEAK as well though and we haven't experienced this problem on it yet (but it's intermittent so it might be there, just hasn't happened yet). I'm currently running conservative governor + SIO, but it has also happened on conservative + NOOP.
While I could just change a bunch of sh!t and hope it goes away, I'm more interested in figuring out what's causing it, and fixing it properly. How can I figure out what's going on? What will log this kind of thing? What do you guys recommend?
Thanks!
this is really easy/simple. flash a different kernel. all devices are not created equally so you need to just try everything that we have and see which best fits your device.
if you had this issue on 2 different roms with the same kernel then you've answered this question in your post for yourself. it wasnt even necessary to post this dude. change kernels. done.
some phone like neak kernel, some phones dont. some phones like siyah, some phones dont. you cant "fix" that unless you get a different phone and try neak again. but even then it my not "fix" this issue because nothing is broken.
Well, what if it's something as simple as the governor I'm using or an undervolt setting? I'll probably flash back to your kernel though, but again it'd be nice if I could figure out exactly what the phone is doing when it's "super-lagging".

If you're undervolting when this issue is happening, change it back to regular voltage.
I can attest to the slow downs and the screen lock ups. I have been using Tasks kernel for the past week and a half. Going back to try NEAK one last time. If it gives the same results I'll have to give up on it. I don't under volt hardly at all by the way. Like maybe -25 per step so it isn't that, and when I first experienced the issue I tried Evey possible io scheduler / governor combo under the sun. All yielded same darn results.

I've only used Task's (CM9) kernel and NEAK, and I haven't yet experienced any slowdowns with Task's, but I really have no idea what kind of optimizations his has, haven't found any information on it published so I can't say what's different between his and the NEAK kernel.
What kernels have you had problems on?

Stock & Siyah. My issue with it wasn't major; it just isn't as polished as GB. The difference is noticeable.

When mine gets laggy, I usually pull out the battery and put it back after 10 min or so. If you are leaving the phone on more than 2-3 days at a time, that could really hurt the memory and phone performance. The phone usually runs on 300 mb but it will run about 700mb ram after 3 days (even force closing everything).
It is not mentioned so I just wanted to cover all bases
After posting about giving NEAK another try, I did. And within 10 minutes got an extreme lag slow down while typing. Didn't touch any settings kernel side. So I flashed siyah kernel and so far no problems. Sux too. I liked NEAK.

I have been running Siyah with Task's AOKP and have had zero lag and great battery. No UV or OC.

Posted this in NEAK thread but also posting it here:
I just installed the new AOKP, used kernel clean script and installed NEAK 2.0.5x, then went into the NEAK Pro config and changed my governor to Conservative and sched to SIO. Rebooted, opened Scramble with Friends and immediately got superlag.
Turning off the screen and waiting 20-30 seconds fixes it (long enough for the phone to go to sleep), but nothing else short of a reboot will help. I can leave it like that for an hour (if I don't let it sleep) and it'll still be uberslow.

[Q] Overheating Issue?

I have searched our Forum for anything on this phone overheating and there is one thread that I came across, but most people did not really have this issue at all. I mean in normal usage doing pretty much nothing my phone holds at 45-50C, given that is with all four cores operating, and if I play a game the cores have reached 70C and up, I am almost certain that is simply too high for this phone to be operating at. Also, even when I use eco mode the phone still idles around 40C and will reach temps as high as 64C. I am just wondering if I am alone or people have actually tested this also and have results similar to mine. I was hoping maybe there might be potential fixes for this or would I need to get a replacement device?
Don't have a great answer for you but I can tell you the phone has some safeguards in place. One that I am aware of is the screen brightness will self-dim until the phone temp drops.
Arlington- as in TX.?

Yeah, I live in Arlington, TX. Yeah, I noticed the self-dim feature, but that happens way too much, and too often, I mean I rarely get to use the phone at 100% brightness and no phone should be like that in my opinion. I am just curious if other people are dealing with similar issues, but I am checking eco mode now and my temps on idle are 36C-38C, its when I actually use my phone as a quad core phone, shocking, that it gets waaay hotter. I mean its hot on the back of the phone when I touch there and when I check the temp with an app. I feel I should be able to use my quad core as a quad core when need be, not have it get so hot its unbearable to hold, plus I don't want to do any damage with it reaching 70C temps.
Me, too in Arlington.
I would definitely say based on that it would be a good idea to exchange it, those temps are a bit much.
All og's get hot like that when playing games, etc. It is just how it is designed - like it or not / love it or leave it, lol.
I would have preferred they make the phone a little thicker with more heat sink so it could run full speed all the time when needed.
But they didn't. So, oh well. Maybe my next phone will fix that someday.

Darn, I was hoping for something else, ha. Oh well, guess I will be dealing with that then, meh.. By any chance could you tell me your temps you are getting? So, I know what is normal for the device?
With 5 mins. light use (wi-fi, web, phone call, 2 texts, no gameplay) 25.4 C

If you are using a phone for AT&T network on T-mo, it is possible that is adding to the temp prob, not an expert here just an educated guess that the more it tries to find network signal the warmer it may get.

Yes, but this happen on wifi only with data and no sim card installed, I am waiting to get an at&t sim card, lol. Shouldn't have done it online, but it cost 99 cents, instead of $15 bucks in the store.

Well, the strange thing is that I reverted back to stock everything, no root, or unlocked boot loader, and my overheating issue has been solved.. Weird. I only get around 35C even doing a benchmark with all four cores running at the same time. I think the Base rom and kernels still have some bugs that need to be worked out. I idle at 22C now, woot!
Glad to hear that!! Nice work.
am using the new build from Team Nocturnal with no probs. You might want to read through the thread first as some are having issues.... point is, no overheating and battery life seems good so far.
One thing I learned by testing, even going to the extent of exchanging my phone 2 days ago - if you charge your phone while it is off and unplug the charger it will drain the battery because it does not shut down the charge animation. The workaround is to simply turn the phone on and let it boot, either leave it on or then it is ok to turn off.

Oh wow, I did not even know that was an issue, ha, well, thanks for the heads up on that and I think I have to send my phone off to LG sadly, according to AT&T, but when I get it back I will be looking into their new base rom, I did skim the thread a little, and I am glad to hear there is no overheating. I am not sure if it was a kernel issue or the base rom itself, which is puzzling.
You may have selected Sk8's kernel during The Base's installation. I can't speak for it myself, but it's different than the stock kernel and may have been causing the problem?
Speculation at best.
No worries, Its what I am doing right now, just speculating, I mean I actually selected both kernels in the base rom, and tested them out. I was trying to figure out what the issue was. I think it might not have left me do a clean install, as I did select Sk8's Kernel first. So, I am thinking that the kernel stuck, even when I did a full wipe, before reinstalling and using the other kernel. I also was getting Kernel crashes, and it kept showing up a kernel crash screen, and asked me to go into download mode to store the dump file on my computer. I am new to android/Linux things, I am far more familiar with Windows based things, but android is the freedom OS of mobile devices. I like the customizations and things you can do with it, lol. Its sweet, and I am learning everyday, so that I can possible become a Dev later on. I have ported some things before and I know other forms of coding, just not the required programming languages for Linux.
My guess would be Sk8's kernel as well, I know it has the gpu overclocked, so if you are running graphics intensive apps it doesn't surprise me that you can be getting overheating issues.
Maybe try the bootloader unlock again to reinstall the freegee kernel...
Just a suggestion.

v1:
- initial release
v2:
- added GPU OC and UV settings
v2.1
- revert GPU settings until i get them more stable
- add voltage control via sysfs (use system tuner to select your custom UV settings)
- fix the black screen issue for alot of users
v2.2
- fast_charge on usb (icon will still show as slow charge but it will actually charge faster)
- cpu tweak to enable use of all freqs in high stress times like games and benchmarks
^ That is the change log for Sk8's Kernel, the gpu isn't overclocked anymore, it was in the initial release. So, I know its not that, and as I stated in a previous post I tried both of them, but even when I wiped everything, I think that Sk8's kernel was sticking. The reason I say this is even after a fresh install and selecting Freegee Kernel during installation, when the rom booted back up it would show Sk8's Kernel, and I would get Kernel crashes, which would also lead to a Crash screen, asking me to go into download mode to save the dump file. Though even after messing with that and monitoring it for several days, its hard to tell what it was, but I do know I am not having the issues anymore when I brought everything back to stock, I can assume it was one of the kernels, a combination, the base rom, but I am not 100% sure.

Shows what I know, lol.
I was going by what I read for the Base ROM Aroma installer description, maybe the Base is still using an old version, but if you installed it on your own, then you should have been the latest.
Sorry, lol.
