Hey everyone, just thought I would let it be known that (at least on my phone) overclocking past 1.8GHz causes horrible clicks and pops when listening through the headphone jack. I am using the Rogers Stock ROM with the latest KT747 kernel, and the issue appears when clocked to 1.89GHz, even though the rest of the phone runs stable. Took me a while to track down the problem!
I was hoping people with other kernels/roms/configurations could weigh in to see if this is an isolated or a widespread issue. For the time being I have just decided to overclock manually when it is needed.
EDIT: It appears after more testing that it was the kernel itself. Switching to stock kernel fixed the problem.

isn't your phone blazing hot to the hand?

Suprisingly the temperature increase is hardly noticeable. I tested while playing N. O. V. A. 3 and a few other games. My One XL got burning hot while overclocked to 1.7GHz, even though it's the same chip, which I find strange.
I had this probelm as well on my SGS3, ended up exchanging my phone for another reason and the new phone doesnt do it anymore.

The galaxy s3 explodes with stock temps, I would be afraid to oc to 1.9GHz Oh, and I would edit the title from [FIX] it's kind of misleading since there isn't a fix here.

I'm still trying to figure out when you would "need" to overclock.

I'm a power user. I do just about everything with my phone, including lots of gaming with emulators. Perhaps I got a higher than normal quality chunk of silicon, but the phone didn't overheat at all, even when overclocked. The only time it got noticeably warm was while overclocked, gaming and charging all at once.
To those having this problem, it appears it wasn't related to overclocking after all, as the issue appeared a day later on stock frequencies. Changing back to a stock kernel fixed the problem.
In the end I sold it and bought an international SGS3 from eBay. I don't care for LTE, but the Wolfson DAC and Mali-400 GPU appeal to my usage case nicely.

Seeing posts like this just make me cry inside...from the day I first got my phone and activated it, I have been having overheating problems. No one would take my device back so after my 30 day "return" period or whatever, I decided to root my phone to underclock/undervolt to solve my problem....but even know, my phone gets warm by just using stock Browser after a fresh install (not Chrome or anything else) WITH underclocking.

Hi Guys
Well i have install several ROMS wich as HO!NO! full throtlle, Cyanogenmod 9 an 10 stables and Nigthly edition, JellyBam and others that i not even remember and all of them always in some point they just reboots and im really hate it. I use wakelocks app and it works for a few days but eventually it reboot and he battery drain really fast, 8hours in EDGE and just a little chatting on whatsapp and a few calls.
i always wipe system, datvilks etc, im kind of new on this stuuuf but i think im doing it correctly.
Im starting to think that maybe its a hadware problem. Onces i ask some crappy tech gay in a store and he told me that i should buy another battery i dont know why, i thought that he just want to sell me the battery but i dont know.
Can anyone help me or recomend a ROM or something?
I just want a ROM that doesnt reboot and good battery life and i can do normal stuff. i dont care about overclocking or anything like that,
Thanks in advance
I would install a stock rom, either stock AT&T gingerbread or ICS for the Nitro and see if it still reboots. If it does, I think you have a hardware problem.

I would go here first: http://www.att.com/esupport/article.jsp?sid=KB413885&cv=820
This will make sure you are 100% stock. Then if you are still having issues you know that it is a hardware problem. Just make sure you do a full wipe after install.

Sparcots miui ics port is the only rom that has zero bugs, black screens, or reboots for me. I've tried everything else.

Another potential issue is your SD Card.
I've also noticed lately that my Nitro sometimes randomly reboots. I run with the CM10 Nightlies. The other day, after installing a new nightly, it was really bad, almost constantly rebooting. I took out the battery, removed the SD card and let it sit for awhile (like 1/2 hour or so). Then I put everything back together, reinstalled the nightly and it's MUCH MORE stable now (still randomly reboots, but the instances are much less).
Give that a try and see if it helps at all.
Good luck!
Hi All!
I have LG P936 Optimus true hd with vodafone v20c firmware.
It`s regularly several spontaneous reboots per day. I saved logs with one reboot

how it can be solved? Help please!
My solution has been to just stick with Gingerbread.. No rebooting, good battery life even with the stock battery, runs all the apps I need.
I do miss ics/jellybean, but I rather have a stable phone with great battery life than a pretty, unstable bleeding edge phone.
If anyone wants to build an awesome gingerbread/ics hybrid.. Then I am down. Lol.

Can you tell what happened based on the logs?
two P930s (NItro HD), one with hardware issues
I have two P930s. One of them is much more sensitive to ROM settings and I find I need to limit the CPU to 1200 Mhz or so to prevent random reboots.
The other one works well at full 1500 Mhz speed. This particular model seems to have inconsistent hardware build quality. It makes me reluctant to try any other LG devices (a relative has an LG dishwasher that has also been troublesome, with random shutdowns and error codes).
possible causes
1 - bad sd card
2 - bad flash
3 - unstable recovery .
for me , i have noticed the same , and found it fixed once i upgraded my recovery
1 - bad sd card
its rebooting without sd card
2 - bad flash
its rebooting on two v20c firmware what I used
3 - unstable recovery .
I use official kdz firmware only, not cwm
I' ve got the same problem. I've changed the sd card but it didn't work.
Similar issues here with a Nitro that a friend let me borrow while I'm waiting for parts for my other phone. Random reboots on several different ROM's including stock.
I'm going to try Kernel Tuner and up the voltage a little and see if the phone is more stable. wistlo mentioned limiting the CPU to 1200 Mhz and I think he may be on the right track. If the processor cannot handle being clocked to 1500, which is stock, then a common method (at least with PC's) is to either lower the Mhz or increase the voltage. Or both.
I just tried this a few minutes ago and I'll report back later.

Yeah, i remember downgrading to GB to root, didn't use it muchzbut it never once rebooted.
Bought mine last week on ebay brand new (packages sealed and everything), i let it fully charged and started using it.
Came with stock ICS and has been constantly rebooting for the past week.
If i didn't live overseas and didn't have to pay so much money to clear through customs here i would have returned it, but i'm stuck with it and searching for help.
Funny thing is i've gamed on it for hours straight and stability tests for more than 2 hrs and it never rebooted. Then i'll whip out the keyboard to type a message or install an app on play store...or simple web browsing and BAM!....reboots
I've changed to 3 SD Cards even tried without it, still reboots.
All wireless signals off, reboot.
Different ROMS/Kernels, factory reset/wipe, Battery cover off, diff. governors I/Os, Underclocks & Overvolts, tried it all....except going back to GB.
It kind of irks me to know that i came from a GB phone to upgrade to a "new" phone that can only run on GB stable.
It always crashes during some really "stressLESS" stuff, lol. CPU scaling problem maybe?
Also, with no SD Card installed and on boot i get a "SD Card damaged. Try Reformatting" error. Is it normal to get this error with no SD installed?

This definitely makes me think you've got a CPU scaling problem. If you're doing something consistent, like playing a game or stress testing...The CPU will likely stay at a single frequency...But in your case, once you start doing some other activity (which very likely caused a CPU frequency change), the reboot occurs.
Definitely try installing SetCPU and set both the minimum and maximum frequency to something midrange, like 1.2GHz. This way you're locking the phone to a single value (no scaling) and not the max frequency so you won't overload it. Then do what you usually do when it reboots and If the phone stays stable, you'll know the problem is likely an issue with CPU frequency scaling. If it still reboots, at least you've removed one possible reason from the list.

It was suggested in another thread that setting the governor to conservative 486 min 1404 max fixed the BSOD, so I tried it and haven't had a single reboot since I posted the last time. I was lucky if I got 30 min before trying it out.
I agree with you, definitely seems to be CPU scaling issue.
Conservative gradually increases the speed compared to the massive min to max spikes you'd get with ondemand.
I will try that with CM10.1 Rc2 with Wind Kernel. I got a few reboot when using my Calendar app for example, while low on battery.

Yes. That tends to be one of the bigger complaints about CM10.
i think cm10 is default tailored more towards performance, you can tweak it or go with a liquid rom if your concern is battery life, i also recomend taking a look at something like this:
http://www.droidxforums.com/forum/droid-x-hacking-guides/14714-how-optimize-battery-life-speed.html
this guy seems to know his stuff, i personally prefer performance over battery life thats why i own a p930 to begin with. but i perform the battery calibration twice a month using his steps, and ive seen it improve my battery life durastically, you might want to start there and tweak according to your needs.
It has been reported that cm10 kernel keeps waking up the phone, i.e. no real deep sleep, causing a more drastic battery drain. work is being done to fix all the bugs with cm10, you may give Quattrimus a try, I found it very good with battery, especially true for rc2 (last version):good:

I cant edit the post so here is the link to Quattrimus. good luck!
interesting never heard this, since 10.1 releases are starting to come out, the real question now is, have they fixed that bug for 10.1, the answer is probably yes if they were aware of it in 10.0 but it would be nice if someone knows for sure
edit was just spelling
Even factory ICS is not as great as Gingerbread. But yeah, running CM10, my P930 feels like a space shuttle ... in that it must remain tethered right until takeoff.

your probably using it more if you just installed it no? how long have u been testing it
If I had just done a bit more research on CM10 for the Nitro I probably wouldn't have put it on there. Oh well. The good this is that I do have JB now.
DS battery saver provides decent battery life with moderate use. Now all we need are fixes to the kernel/ROM to provide better battery life when actually using the phone because DS battery saver is mainly for screen off.

I always use my phone heavily; regardless of testing or not. Ive established a pretty good baseline for how my battery performs with almost every rom available for our device evenly l except cm10+. On most other Roms I can get around two hours of constant use, cm10 half that

I noticed my phone gets HOT on CM10. Haven't tried any CM10.1 ROMs yet. I'm guessing the kernel needs a bit of tinkering to get it running efficiently with our hardware. Battery drains fast even idling. I don't think the phone ever goes to deep sleep.
It definitely goes deep sleep, according to better battery stats app anyway. I'm really digging cm10.1, especially oc'd using windkernal (scoring 4000+ in quadrant consistently). The nitro is a complete beast right now, but I dunno if I can afford to sacrifice the battery life so drastically for a little performance.

Hello, I just flashed CM11 on the Lg Optimus G Pro (E980) and i have noticed a battery drain about 15% (or more when playing games) per Hour. Is there any way to fix this issue?

helps if you change cpu from ondemand to interactive in preformance settings. phone will charge faster too. If you dont have developer options and preformance settings in cm11 go to about phone and click on build number 7 times to turn them on.
For what it's worth, I was seeing high battery drain (and little to no Deep Sleep) with CM11 and Vanir 4.4.2 while on baseband CM9615A-CEFWMAZM-3.0.113012. I flashed baseband BM9615A-CEFWMAZM-3.0.113012 and battery life and Deep Sleep are now what I would expect them to be.
There seems to be some concern about flashing that modem.
Also, I haven't found a flashable zip for CM9615A-CEFWMAZM-3.0.113012, so to get that one installed I believe you have to return to Stock.

I haven't flashed separate modems since 4.3 ROMs and I've had no deep sleep troubles.
I always wipe internal SD, data, cache and system before flashing. If you don't wipe the internal SD, some leftover data from previous ROMs are still there which could cause problems from my past experiences on older devices.

Dear Senior Memeber,
In layman terms, how one flashes baseband BM9615A-CEFWMAZM-3.0.113012 on a LG Optimus G Pro ATT (E980) ???
go back to cm10
Ive tried everyrhing ... Cm11 is still not stable enough and using so much of my battery.
I changed it back to cm10 and everything is finaly got back to normal.
Cm11 fix this issue and fast!!
I've been using the Mahdi Rom and the dyn.Kernel since i got the Pad, and it works great so far.
With both allowing undervolting of the Pad, i've been wondering why no one posted anything about it so far.
(wanted to read up on that first before i try it myself, heh, a couple of things went wrong with my nexus when i tried that before )
I've gotten very good results with undervolting on a Nexus 4 that has a similar powerhungry chipset (after a lot of trial and error), Battery life effectively doubling (with a few other tweaks).
Also the range of the undervolt (CPU binning) was CPU dependent as i gathered from the Nexus.
su
dmesg | grep PVS
results in a '1' for me. (yay, slowest)
Is this still relevant for the G Pad, and has anybody undervolted yet?
Post your results if you have any.
I don't know how to undervolt, but I want to. How do I do it?

Flash Mahdi rom then the dyn.Kernel, and go into Settings where you can see 'Performance' then swipe to the right a few times.
The CPU frequencies are there with the mVs.
I doubt if it will make a difference on the G pad since it seems to be mainly the screen that is eating all the battery , and not the processor.
