There's no solution for this problem. And if you will flash another rom or another official software, no matter GB or ICS , the problem will stay. I don't know what happens, but updating creates some error, possibly in hardware.

And you know, I am really disappointed with that. I had tried every rom, and all kdz software, downclocking, disabling tons of functions & options. Nothing prevents reboots. It freezes for a while and then reboots. In some roms it can shuts off instead of reboot. And that's it. The last chance I think is jtagg reflashing.
[LG Nitro HD] hhhmmk:
I had same random reboot & sleep death problem after performing unbrick.

I tried several times of unbricking to correct this and installed GB & ICS, almost every CWM Rom without sucess.

Finally, I tried v18f.exe version when my phone was in download mode.

After that, I havn't had any single reboot or sleep death. I'm currently using v20c without CWM.

What I did was:

1.Install V18f leaked version in download mode.

2.Root with TPSparkyRoot_ICS

3. you can stay with v18f if you like, but I prefer to go v20c using "dd if sdcard boot.img .....method.." with v20c img file.

In my opinion, unbricking with korean rom may have some compatibility problems in some area besides boot, recovery, firmware, band, system partitions at least in my phone.

Becasue before I perform unbrick with korean rom, I never had reboot or death problem with Ho-no bell rom, kernelpan1c, cm9 and p936 rom.

Anyway, after install v18f.exe, my phone is perfectly okay.

I hope this help some of you suffering from random reboot.

Problem Solved!!!

You are right dude. I also had frequent reboot issue with ICS Roms. Then, I put the phone in download mode and installed v18f(exe). Amazingly, the phone is super stable now. Thanks a lot for sharing the info. Just a question : can I now flash CM10 over this? will it cause reboot?
[LG Nitro HD] Rdelapaz:
still not solved: (

I try installing v18f on my Telus P935, this version: http://xdaforums.com/showthread.php?t=1668476

looks good, but it follows restarting randomly, like the official version V20E.

anyone knows another possible solution? please :(
[LG Nitro HD] normaaaan:
What Baseband is your phone showing in 'About phone?'
[LG Nitro HD] Rdelapaz:
Baseband version

APQ8060/MDM9200
[LG Nitro HD] normaaaan:
Sorry ...

Sorry, my apologies, I forgot how uninformative the stock display is.

You can get at what I was looking for by installing "System Panel Lite" (free) and looking under "Dev Info," and then the entry under "Fingerprint."

However, skip that and perhaps just go ahead and re-flash the baseband. I don't think it can hurt. Druminst has posted zips that install the basebands with ClockWorkMod at http://xdaforums.com/showpost.php?p=30451467&postcount=1 You have to go to his "more extensive list" to get to the baseband_flashable_P930_ATT_V18f.zip file.

Hope this helps ...
[LG Nitro HD] Rdelapaz:
A OK, thanks.

Well, I will try.
[LG Nitro HD] axeman007:
Random Reboot LG Sucks!!

I tried a lot of combinations : Unbricking several times. Installing most of the CM 9 and 10 Nightlies, HO!NO! roms, V18F Stock, V20c etc.. After all this, the end result is :

LG Nitro HD reboots randomly, especially when you use play store and settings.

And I'm sure It is not a hardware problem. Because, the stock GB Rom works without a single reboot.

This showcases poor support from LG and their muggy kernel build.

Now, I feel sorry for selling my good old Samsung Captivate for this crap.!!! ( JB was working beautifully in Captivate ).

If anybody got any idea regarding fixing the RANDOM REBOOT issue with ICS, Please please please let me know.

Thanks
[LG Nitro HD] drumist:
Have you tried installing official v20c (via LG tool, not CWM) and then doing a factory reset?

Have you tried using a different SD card (or reformatting it), and/or getting a new SIM card?
[LG Nitro HD] axeman007:
I tried installing v20c using official LG Update.( But haven't done a factory reset). Problem persist.

I'll try these methods and get back to you. Thanks drummist!
[LG Nitro HD] Cam R:
I did the factory reset right after I updated, it still was rebooting.
[LG Nitro HD] drumist:
The next thing I'd try is installing a P936 KDZ using unbricking method in the hopes that it will "fix" some partition that is causing the issue. You won't be able to root it directly (need to use KeepRoot method), but you should at least be able to use it long enough to confirm whether or not you experience any reboots.
[LG Nitro HD] fguzmant:
Same reboots on v20c ICS

I have the same problem, there is a thread on LG about it but without any solution, I have to return to GB and put my LG Nitro on sale.

http://support.lgforum.com/lg/topics/problems_with_ics
[LG Nitro HD] sookster54:
Wow, so no real solution yet, my Telus P935 STILL reboots after sending it in to Telus/LG repairs, they said they couldn't find anything wrong.

I'll have to try the v18f too.
[LG Nitro HD] normaaaan:
Yeah, no real solution. I just went through all of the Telus, Bell, and AT&T basebands that Druminst has posted, and v18f does it the least in my experience.

It seems that some kind of radio parameter has an effect as I had no problems in Toronto over the long weekend - where I had a strong 4G/LTE signal all of the time.

So my hypothesis is switching states (UMTS to HSPA) is a factor. I have also noticed that the reboot almost always happens when scrolling - a quick demand on the CPU (and never happens when the screen is on). Tomorrow's experiment is running the performance governor whenever the screen is on.

I wish we could get the Telus GB baseband (v10j IIRC) to see if that works.
[LG Nitro HD] fguzmant:
In my case, I only have HSPA+ (shown as 4g on the Nitro), It's strange, but with GB, everything works fine, no reboots at all, but with ICS (stock or Cyanogenmod) reboots appear, I try almost everything, flash other basebands, installing stock roms using LG tools (with factory resets) but nothing works, reboots always reappear.
[LG Nitro HD] sookster54:
Reboots seem to happen when scrolling through the screen (settings, scoremobile, Maps, etc) or when downloading apps from the play store, nothing else seems to cause it because when I only use the phone for text and call it doesn't seem to ever reboot.

Wish I can find a way to revert back to Telus v10 GB.

PS- I forgot to mention, I went into *#*#4636#*#* and set the radio to WCDMA only, so far so good but I haven't done a whole lot to the phone yet- the device seems to respond better too with smoother scrolling. I have a funny feeling it has something to do with the WCDMA/LTE radio flipping that causes the reboots.
[LG Nitro HD] normaaaan:
Here is what I have found that reduces rebooting on ICS [on Telus] - in rough order of importance:

1. Turn packet data off in settings when not needed - not very practical if you are like me and don't have home Internet, but it works.

2. Another not-very-practical suggestion - Be in an area with awesome signal. I don't remember a reboot in Toronto. In Ottawa, I get much less reboots at work (ok signal) than at home (awful signal). Under the same conditions, my Galaxy Tab will bounce between a weak (data) signal and no (data) network connection - the P935 will reboot.

3. Use the AT&T v18f baseband. It isn't as fast as the Bell or Telus v20e (which reboots way more) or the Bell v11a (which works well on data but doesn't like the phone part), but ...

4. Increase the minimum CPU clock speed when the screen is on and use a very responsive governor (e.g., interactive, ondemand). The phone rarely/never reboots when the screen is off. When the screen is on, putting a sudden load seems to be the trigger to a reboot. I had the minimum up to around 800MHz. (Overclocking had no effect.)

5. Hardware 'mod' - DO AT YOUR OWN RISK - On my P935, the SIM slot was quite loose. The SIM slid in and out very easily. A very gentle press down on the metal SIM slot with my finger made the SIM slide in and out with a little bit more resistance. I used to have reboots when the phone got hot - those disappeared after this adjustment. Just don't push hard, as the metal SIM slot also has to contact the back of the phone to transfer heat.

6. Turn off all eye-candy. Transitions, animations, live wallpaper ... turn them off. Set the animation scales in developer options to off.

7. Use a different launcher. I haven't done all of the comparisons, but Nova Launcher gave me less reboots than CM9 Trebuchet (again, all eye-candy off).

Your mileage may vary.
[LG Nitro HD] sookster54:
Rats, still rebooted when using the camera. So it's not the cell radio then.
[LG Nitro HD] normaaaan:
I am pretty sure that most of the reboots have something to do with how the radio interacts with ICS - the radio interaction can't be discounted unless you had the phone in airplane mode when the reboot happened.

The phone is just an ARM computer running Linux - except that the radio has priority.

BTW, I tried WCDMA-only as well, but it didn't help - I think that it is the switch between UMTS and HSPA(+) that seems to be the culprit. Telus has no GSM (2g) network - that might help narrow the issue. I did some limited testing with the phone on Rogers (non-LTE SIM) which worked fine with no reboots, but I also live a block away from a Rogers tower so I have lots of signal.
[LG Nitro HD] sookster54:
I don't think the SIM has anything to do with it, I am still using the old HSPA SIM, when I got this phone I was asked if I wanted to upgrade to LTE and I said no because I don't use data that much to need a faster connection.

Also it still reboots when in flight mode.
[LG Nitro HD] fguzmant:
The problem it's with ICS as been already told, and some Nitro owners don't have the issues so that’s the main reason to think that it's related with radio and signal, GB work just fine in all cases. I will try the latest CM9 nightly, I read that it's bug free.
[LG Nitro HD] sookster54:
You mean the CM10 nightly? I loaded that and it's much faster in response, and then it froze & rebooted when I pulled down the notification... hahaha

Or were you referring to CM9 nightly 20120916 one?
[LG Nitro HD] fguzmant:
I was referring to CM9 20120916, CM10 it's very unstable for me, I've installed it yesterday, since then, I have only 1 reboot (not freeze only reboot), I hope that it was because of the installation of gapps and all the other apps.
[LG Nitro HD] sookster54:
OK I figured as much, I'll try 20120916.
[LG Nitro HD] waxinpoetic:
Just upgraded to ics and was doing fine until I drove into an underground parking lot and it rebooted. So I think it must be a signal issue.
[LG Nitro HD] sookster54:
I will have to do more multitasking while in flight mode to see if it does it, multitasking is usually what causes my phone to reboot (texting in Handcent, using camera, viewing pics, scrolling through Scoremobile, finding locations in Maps).

Funny part is of all the time I've talked on the phone, it has never once rebooted, only when using apps.
[LG Nitro HD] deemson:
That's it! Especially when scrolling something. It freezes for a while, than reboots. Am I right?
[LG Nitro HD] sookster54:
Yes, it's possible considering it still happened when I was in flight mode- so it can't be specifically the radio. I think there might be code in ICS that causes a spike on the CPU which causes it to barf.
[LG Nitro HD] fguzmant:
I was thinking that it could be something related with video (scrolling, camera), I try to use the standard Adreno 220 ICS drivers (using CWM flashable drivers) but I can't manage it to work.
[LG Nitro HD] wistlo:
LG 930 restarting CM10 random restarts; USB charging

See updates below.

I have two LG930s rooted via the Korean ROM method with CM10 Nightlies.

Both show random reboots. One is running the 20121001 nightly and is used primarily for texting, Spotify, and phone calls. The other (mine) is updated every couple of days and is running SetCPU, CSipsimple.

The phone will sit solidly through six hours of VOIP (CSipsimple) without a problem.

Reboots and freezes occur most often when scrolling a screen in Play Books, Spotify, Dolphin HD Beta, or the stock browser. There seemed to be a slight increase in reboots and freezes when using Spotify via Bluetooth (the bluetooth receiver is a recent acquisition). Frequency of reboots and freezes has varied from almost every five minutes to once a day or so. In most cases, the phone freezes, the screen will brighten slightly (an artifact of the automatic brightness function, I suspect), and one or more long presses on power is required to reboot. In about one of six freezes, a battery pull is required.

SetCPU would hang frequently with profiles enabled and a reboot or freeze usually follows shortly after, within five minutes.

I am trying the method described above using SetCPU to keep the clock speed up whenever the screen is on.

Incidentally, I notice that on USB the battery will charge very slowly if a VOIP call is active (which keeps the screen on, as I need to see call status). If I limit CPU to just over 1000 Mhz, the battery will charge much more quickly. AC charging seems unaffected by CPU speed settings.

Update 2012 10 23: running current nightly with SetCPU configured to keep CPU speed over 800 Mhz when screen is active and limited to 3G (no LTE, no 2G). That configuration appears to be stable, with no reboots or freezes for over a day. I then enabled 2G/3G (no LTE), and got a screen freeze/reboot within one hour of use, while reading on Google Play Books. Freeze most often seems to happen after a force close from SetCPU. Also, freezes are nearly instantaneous if SetCPU widget with live numbers is loaded, much less frequent without widget.

I will continue to try 3G vs 2G/3G and observe stability. (I kept old 3G data plan and SIM, so I cannot test LTE.)

Update 2012 10 27 Reboots after screen usage are again frequent, particularly after using Google Play Books page turning function, either via screen or volume rocker click. The Navigation app ran for 300 miles of driving (about 5 hours) before rebooting spontaneously. Multiple reboots and freezes since then on 10/26 nightly. The 10/27 nightly seemed solid at first, but then the reboots started again.

I bought these phones for $36.01 (a "$0.01 upgrade" plus the mandatory upgrade fee) and now I'm stuck for two years with them. I am still using 3G data plan, and may revert to old HTC Aria--slow and Gingerbread only, but no reboots there. As for LG: Life is Good? No, "Let them go"; I would have gone for the Samsung had I known these would have been this much trouble. I may try MIUI ROM just to see what happens.
[LG Nitro HD] daobr:
I have also just got a Telus Optimus LTE (P935) and as soon as I upgraded to ICS have had the same reboot freezing issue.

Is LG doing anything to get that fixed?

I really like the phone and it is a shame ICS has not been properly ported to the Optimus LTE hardware.

It also seems LG don't really care about it at all.

Oh well will return the defective one I got and may have to get a Samsung Galaxy I guess...
[LG Nitro HD] hereric:
I honestly don't even think that we have defective optimistic LTE's, I think that the quality we've been presented with is the status quo unfortunately
[LG Nitro HD] daobr:
Just had a few more reboots, this time I didn't even touch the phone, it happened with the phone on the desk running Tunein radio.

Could no longer stand it, removed my sim card, and left phone on with Tunein radio running and about an hour later another freeze/reboot cycle this time with no SIM card on it.

It's back on the box and being returned tomorrow.

Unbelievable that LG has not recalled those POS phones yet.
[LG Nitro HD] sookster54:
Trying to figure out how to flash v20e back so I can send it back to Telus, I threw the V10F back on there just now.

The HTC One S sounds tempting.
[LG Nitro HD] Sparcot:
I think LG just forgot about it...
[LG Nitro HD] normaaaan:
We'll see what happens. It is a Telus issue AND an LG issue - users on Bell don't have this problem, and using a Bell P930 on Telus does have the problem.

The only baseband that I know of that doesn't have the problem is v10a (on Gingerbread). The KDZ file was available a few months ago (elsewhere, not XDA), but the file is gone from the filehost now, and LG has changed their server structure so I couldn't grab the original v10a KDZ using the tool posted on XDA. (Somebody else might be able to, please try!)

If someone does have the v10a KDZ, then please post a link!

The P935's in the Telus stores still have v10a Gingerbread, but the bootloader is locked down so root may not be possible. A newer root method might work on v10a, I don't know. If so, then we could get the "good" baseband.

If you got your phone within the past 30 days, and upgraded to ICS, then I would consider taking it back to the Telus store, going through the DOA process, and getting a new P935 (which will have v10a and Gingerbread).
[LG Nitro HD] hereric:
I am a Bell P930 user and I ABSOLUTELY have this problem. These phones are massive pieces of s**t, and I can't believe that they made it to retail with the slew of problems they have. Look at ANY local classifieds website, I can almost guarantee there will be at least 10+ P930s for sale at astoundingly low prices.

I might not have the problem as bad as P935 users, and I've mostly been using CM10 and CM9, but where AT&T users have reported smooth sailing, I've been faced with plenty of random reboots. When HONO had his custom kernels out, overclocking my phone at all would cause the problem to become much more pronounced, and I believe that we really got shafted with the Snapdragon S3's they used in this phone.

The Optimus G / Nexus 4 are so very tempting, but I don't know if I can bring myself to ever trust LG again. I want a new phone desperately (even though I only bought this one in February) so I'll have to see what the holiday season brings this year.
[LG Nitro HD] Cam R:
Incorrect. I'm with bell using a bell phone and I have this problem.
[LG Nitro HD] normaaaan:
Bell users can downgrade to Gingerbread. Telus users can't downgrade to Gingerbread.

In any case, every province offers consumer protection legislation - albeit to various extents - and the carriers themselves are regulated federally by the CRTC. If folks aren't willing to exercise the laws, then sure, sell on Craigslist. Similarly, if one bought the phone off of Craigslist, then yes, buyer beware. However, if one bought new from a carrier, then you do have legal recourse to have a working product (more or less, depending on province). Use it!
[LG Nitro HD] sookster54:
How can Bell users downgrade?
[LG Nitro HD] hereric:
Debricking guide, or manually pushing the .IMG files with adb
[LG Nitro HD] aldo90:
The phone reboots because the temperature hit 40°C along with the cpu spikes. I only have used ICS, dont know if the problem occurs less in GB
[LG Nitro HD] Cam R:
Well it didn't happen once to me for the 6 months I was on gingerbread.
[LG Nitro HD] miji2:
This is definitely a Bell problem too. Worse, out of the two P930s I have, one is rock solid and the other one is flaky as f@$%. So not to say everyone is experiencing issues due to the same problem (since clearly there are QC problems here), but here are my experiences and some ways I found to mitigate.

To start, in my experience, the problem for me is not related to temperature or baseband.

The stable P930 has been running v10a as well as v20e with no changes to stability. As well, I can drive the stable P930 up to >50 degrees C without any stability issues (aside from the voltage regulator shutting down charging - but that's normal).

But the crazy P930 is just as unstable on the v10a baseband as the v20e one. More so, throttling MHz only mildly covers up the problem but does not go away. Also, after stabilizing my crazy P930, it's just as stable with the v10a baseband as v20e and stable when baking the CPU at 50 degrees C.

So here's what I did to stabilize it. Disclaimer: this is not permanent and will require further work, and not for those on stock ROMs, but it allows me to enjoy using the phone again. As well, if you've never flashed your phone before, do your homework as you will likely brick your phone, so please don't do this.

1. Flash the cm-10-20121017-NIGHTLY-p930.zip (http://goo.im/devs/cm/p930/nightly/cm-10-20121017-NIGHTLY-p930.zip)

2. Factory reset

3. after each reboot, set the "disable HW overlays" option under Settings > Developer Options > Drawing section

That's it. No more random reboots, no more sleep of death while charging.

Some notes:

- the PITA (ie, full wipe) is essential, without it the reboots persist

- this trick did not work for me with previous nightlies .. I tested it to confirm

- subsequent nightlies have declining stability, even with the full wipe. At around the Oct 25th, random reboots are back again, full wipe or not.

- battery life is not as good as with some previous ROMs, but I take some stability over battery life any day

Having said all that, I am not sure why the 20121017 nightly does this for me, other than a number of changes done to the LGE kernel tree the previous night. As well, I am not sure which changes after the 20121017-20121020 nightlies undo the magic; nothing from the change log stands out.

In any case, that's just my experience up until now. I hope someone on CM nightlies can validate or dispute my claims so we can understand it better. I am continuing to experiment in order to tame the beast.

Good luck.
[LG Nitro HD] quijibo:
Is there a mirror for this file? The link doesn't seem to be working.

I also have a rebooting phone and would like to try this before I return it for a replacement.
[LG Nitro HD] normaaaan:
Hmm. Interesting comments! I guess that I should have said that Telus users seem to be more vocal about it than Bell (or AT&T, etc.) users.

My phone was unusable on ICS (100% stock Telus upgrade). It rebooted every few minutes, and had BSOD multiple times a day.

I am scared to hear that it may simply be a case of some component(s) being not up to the task.

BTW, I thought only the Telus P935 had the v10a baseband for Gingerbread? The Bell P930 has the v11a baseband for Gingerbread AFAIK.
[LG Nitro HD] hereric:
You can flash any baseband you want using cwm and drumists flashable zips
[LG Nitro HD] sookster54:
I managed to get stock v20e back on mine and sent it in for repairs for the second time, the first time was back in Aug and they couldn't figure out what was wrong with it. They said if they can confirm that it's still doing it, they'll offer me a different phone so I said HTC One X, will find out in a couple weeks and see what happens.

You should do the same, call Telus directly (ask your local Telus for the phone #) since the reps at Telus can't exchange phones for you, only send it in for repairs.
[LG Nitro HD] normaaaan:
I hope it works out for you! In my case, the store salesperson told me it had to go in for repairs three times before a Telus rep would be able to do something.

BTW, the Telus website is showing the One X+ and Galaxy Note II coming soon (and the LG Optimus G coming Nov 13. ..)

I am with Telus because of their customer service - guess we'll see how good they are with this! (They've been reasonably good to me for the past five years :)
[LG Nitro HD] sookster54:
Yeah I know about the One X+ but it's not in the exchange offer but the One X is. And I think it's due to get Jellybean soon... but this time I'm going to delay the update and wait for the feedback.

Telus are OK, been with them since they took over BCTel back in the 90's.
[LG Nitro HD] normaaaan:
If LG's repair facility can't fix the phone - maybe I'll be third time lucky - and Telus is good to me, then I hope that the Galaxy S III is an option. Some people over on the One X forum here are having some issues, although the phones don't seem to be rendered unusable like my LG has been.
