My workaround

Well, almost six days in a row with no reboots nor bs.

I tried this:

With baseband 530 and CM nightlies

1-In CWM, before installing the rom:

Wipe user data/cache

Wipe cache

Advanced->wipe dalvik cache

Advanced->wipe battery stats

2-AND repeat ALL FOUR wipes in the REVERSE order

3-Install ZIP(ROM)

4-Install RIL

5-Install Gapps (http://goo-inside.me/gapps/)

6-Reboot

Optional: afterwards, restore with TB ONLY apps with their data, but not system data

It worked for me (fingers crossed), hope also helps someone else as desesperated as I was.

My auto shutdown experience is after installing Flash 10.3... keep it at 10.1, it is more stable
[LG Optimus 2x] mas2112:
I just bought the LG Optimus 2x about 5 days ago. A few minutes after turning on the phone for the first time and plugging into the wall, it automatically rebooted and a few minutes later it went into BSOD and I had to pull the battery.

I've only had to pull the battery one more time, however I experience a random reboot every day or so. I noticed that random reboots seem to happen while my phone is in my pocket. Anyone else notice that? Today, I thought it went into the BSOD, but I just put it back in my pocket and decided to pull the battery later. But 10 minutes later, it had already rebooted and was responsive again.

Today, I installed Galaxy on Fire 2 to test out the GPU capabilities. The game started downloading its data files (~500MB over my WiFi) and all was well until I plugged it into the charger. A few minutes later it rebooted. I opened the game again so it would continue to download and a few minutes later it rebooted again.

I read somewhere in this thread that it might be related to the auto-screen shut-off feature. So I set the shut-off time to 30 min, and the game finally finished downloading.

I'm curious, is every user experiencing this problem? Is there any LG Optimus 2x user out there that has NEVER experienced a BSOD or a random reboot? I'm starting to think it is a hardware issue.

If there are users experiencing no problems at all, it could be that there are different motherboard revisions out there, where the earlier revisions being the buggier/defective ones?

Ok Gentlemen and Ladies update 18:

Dutch fota update 263 mb from V10B (basedband 0405) to V10C (baseband 0622)...

Forced to do it via the LG PC mobile update tool, since my replacement O2X gives an error when checking ota :-(

Update wend fine and the phone feels a lot faster and responsive...

This one had 2 x bsod since the replacement 2 months ago.

So it was already performing far better as the first one which had daily and during

charge reboots, also spontaneous reboots occurred plus the phone generated a lot of heat.

The replacement O2X is by far cooler as the old one also during charge, that's why I think the O2X have hard and software related issues.

Curious how this one will perform local here with the latest radio 0622 :-)

It feels like a brand new phone because it performs far smoother and faster :rolleyes:

Hey.

after over a monthe my phone has some BSODs but only in one situation - when I start playing music via BT Headphones - SonyEricsson MW600. I have those headphones over 2 weeks now and the BSODs started 2 days ago. The strange thing is that when I connect the BT set and start music app it crashes after 5-10 minutes, but then when I remove the battery, start the phone and activate music player, everything is fine. The crash only happens when I disconnect both devices and reconnect them later or next day.

Did anyone of you had this kind of problem? Is there any solution for that?

I am running Stock ROM + Root + baseband 622. It also happened on the BB 405.

Does the BT turned on, but not connected with any device drain a lot of battery? I am thinking, maybe if I won't swithe the BT off in my Optimus, then the problem won't appear, but I need to test it. Or maybe there is any possibility to make the BT run in a background or something?
[LG Optimus 2x] ovocaman:
Hi Guys!

I buyed the o2x from vodafone spain just when it came out to the market, about April 10th. I had several reboot issues (about 2-3 per week)and bsods. I had stock and later MODACO ROM, both with the same issues.

Last week I installed latest baseband 622 with Modaco FR19 Vanilla Edition and since then my O2X seems a totally different handset, super smooth, installing apps much faster, no screen lock problem, no freezing for now, heating problem only with powerful apps, battery has better performance and duration...

I guess everything is related to the new baseband and ril(622), maybe with this new baseband the calling quality is a little worse, but it's not very noticeable ...

Let's see if everything keeps this way and then we could say that LG is finally doing things right...

Thks for this great community!!!
[LG Optimus 2x] fierox:
I have the LG P990 a few days now and it restarts alot, havent seen a BSOD yet.

Havent even used the phone much sofar and just while typing this sentence i hear the restart sound again :(

Sofar the reboots seem randomly, most of the time its just lying on my desk when i hear it restarting.

Still standard software, updating to V10c didnt help.
[LG Optimus 2x] Tangkapan:
Freeze

Hi folks..

i have my LGOS since Wednesday..

updated to V10c right away.. an the phone worked fine so far..

Yesterday first freeze.. no response at all, pull batt. and restart

Today it froze up during phone call.. no response at the screen, no response

at all. but...

wait for it...

the phone call was not disrupted.. phone froze but call continued... :confused::eek:

It seems that my phone always freezes during lockscreen, and screen off mode
[LG Optimus 2x] deep750:
Try a Custom Rom. Try Modaco or CM.
[LG Optimus 2x] bodmark:
try these settings..

.. to ease the pain.

Check box to Stay Awake while charging (settings, applications, development).

And most importantly , you MUST disable the screen timeout completely, to NEVER timeout. You may need to download an App ( quick settings, my settings..) to allow you to do this.

Just remember to manually turn off the screen with the top button (on / off) , otherwise your battery will deplete rapidly.

I don't whether this tip is Perfect, but i haven't experienced any problems for 3 days now.

Hope it helps.

And thanks to everyone who has taken the time to post on this community. I'm sure all this information has helped many..
[LG Optimus 2x] Tangkapan:
well about custom ROMs..

i had a HTC HD2 before and Roms where no problem..

On the LGOS i am a little concerned about what & how on CR
[LG Optimus 2x] Tangkapan:
Any suggestion on the mentioned App ??

Thanks
[LG Optimus 2x] bodmark:
I use " Quick Settings " as it not only does the job but also has other useful shortcuts to various settings ( the app can be accessed via long press on search key; very handy )

There are other apps and widgets available, though I find Quick Settings stable and reliable.
[LG Optimus 2x] mas2112:
I installed the "No Screen Off" widget and set the timeout to never, and it rebooted 3 times within 10 minutes (while I was charging, I should add). But after that, it's now stable.

I noticed the charger gets warm while charging. Perhaps the power outputs becomes unstable when it's warm, causing the reboots. I will buy another wall charger and see if it helps. Perhaps there are multiple reasons for the reboots, charger and screen timeout.

I installed the "Bootlog Uptime" to track the crashes. So far the highest uptime my phone achieved in the past 5 days was 1 day, 6 hours (30h). I wonder what the record uptime for LG Optimus 2x is... It would be interesting to see what the highest uptime people have been achieving with this phone.
[LG Optimus 2x] bodmark:
It's important that once screen timeout has been set to never, reboot the phone (yourself) and then LEAVE the settings alone and DO NOT change them. I did experiment a little with this, switching on and off, trying different timeouts... but ALL of this resulted in problems with rebooting and black screens, if I interfered with the DELICATE Automatic Timeout.

So change to NEVER timeout, Reboot and leave the settings. You can then reboot the phone and use it how you wish, as you normally would.. I haven't had any problems since.

For the record, I've gone nearly 2 weeks in past, without problem.
[LG Optimus 2x] Pfeffa-rah:
After flashing a new rom it started rebooting a lot. Sometimes it did't reboot but just asked my PIN for the SIM card unlock....

I cleaned my SIM-card. Jus moistened it and rubbed it, thats all. And then reinserted it.

I've had no reboots or BSOD's since.

I know, it sounds as if this is way too easy... just give it a try.... worked for me! -so far-
[LG Optimus 2x] Tangkapan:
i can confirm.. after the settings and the MC power patch, no more reboots
[LG Optimus 2x] tdci100:
If you check the uptime, you'll notice that the phone has rebooted.
[LG Optimus 2x] tdci100:
Regarding phone asking PIN, if you check the uptime you'll notice that the phone has rebooted
[LG Optimus 2x] bodmark:
In fact you ONLY need to DISABLE your Screen Timeout. It's not necessary to Check Stay Awake while charging, as once you've set your Timeout to NEVER it already does the same.

Can't believe it was something so simple. Always thought it was a AUTOMATIC Screen Timeout problem..

So come on LG ! We've discovered the problem with YOUR software, so please can you resolve this Automatic timeout issue in your next update. It can't be that difficult , now the problem has been identified.

Don't want to have to manually adjust the screen timeout forever. It is a chore.

Come on LG - you surely can fix it now !

At last a future with no more Black unresponsive screens and reboots !
[LG Optimus 2x] Vertigood:
Currently trying this. Let's see what happens :)
[LG Optimus 2x] xmoo:
Whenever I put the phone in charge, I start op the Android Clock app. This way the phone stays in stand-by. And have a uptime of 140hours :)
[LG Optimus 2x] geistio:
At least for me this workaround doesn't work on the latest CM7 nightly... :(
[LG Optimus 2x] Pwinsesse:
I´m trying this too, hoping it will help my brand new phone. I bought it friday and it have already crased approximately 10 times. Even with the new update...

I must have bad charma or something, the last year I have had my phones to repair every second months.:(
[LG Optimus 2x] bodmark:
.. I'm sorry to hear it doesn't work with the CM7 rom (think the Screen timeout was addressed in that release).

This is what works for me : I check box to Stay Awake while charging

Disable the automatic screen timeout (Set to NEVER)

This has worked for me. I've used the phone normally and just Manually switched off the screen myself with on / off button.

My Phone specs : LG-P990 V10d

FRG83G

Original LG Rom

Baseband - 1035.21_20110405

Kernel - 2.6.32.9

... perhaps this technique only works with specific models...
[LG Optimus 2x] pulsation:
EDIT: The phone just shut down a few moments after having activated wifi, with the new battery, and won't turn on without a battery pull. Another wrong hope...

Hello everyone,

As it looks like that for some people changing the battery solved the issue, I decided to give a try and bought this one on amazon (also aviable on http://www.cellephone.de/ for our german friends).

After inserting this new battery yesterday afternoon, the phone rebooted every 5 minutes (and feared me quite a lot). Anyway, luckily, it stabilized after using a calibration app and charging it fully during the night (with a samsung charger with lower current thant the original one).

The most surprising part happened when I tried to boot in recovery mode to wipe battery stats: as soon as I would release power and volume down keys, the phone would reboot.

Would it mean that something in this battery is not implemented / not correctly sent to the phone's sensors?

Indeed, If by magic it was the case, I really hope it would be the part that make the phone shutdown and need a battery pull off - even if waiting for at least for 2 weeks would be reasonable to confirm that things are really better (at least for my phone as problems could come from a lot of other reasons on other phones).

Cheers.
[LG Optimus 2x] Vertigood:
Well..too soon to tell but my phone has not turned off today..usally it does that once or twice a day. Even installed some apps that before seemed to make the phone crash more often. But now it still is up and running :)

If this works then I can live with it untill THE update comes. My only issue with the phone would then be the batterylife which I don't think is ok.
[LG Optimus 2x] Dead Cell:
Are you saying that you leave your phones screen ON all throughout the charge?

I don't have option NEVER in my screen timeout setting. I have 1 minute, 2 minutes, 5 minutes, 10 minutes etc, but no option for NEVER.

I've left mine on 10 minutes since the last month our so and so far so good except the occasional need to pull out the battery because the phone won't charge even though it reports that it is!
[LG Optimus 2x] doncoop:
Mines set to 30 mins. Tend to charge early eve or at work in morn therefore can just send a text etc when close to 30mins so it doesn't switch off
[LG Optimus 2x] bodmark:
.. Firstly, it is NOT necessary to leave screen on all through the charge (although you can of course).. What I do is plug the charger in (mains, usb or car), then when you see it's charging on screen press the on/off button (top of phone) to switch the screen off manually. The phone will then continue to charge without problems; as the fault SEEMS to be with the AUTOMATIC timeout.

.. Secondly, there is no option in the menu settings to Disable the screen timeout, you will need to download an App from the Market. I use " Quick Settings " , but there are many Apps and widgets that will suffice, as long as they are stable for Froyo.

Try:

Quick Settings or My settings

Screen timeout Widget, screen timeout toggle or Screen Off timeout
[LG Optimus 2x] bodmark:
Just to let you all know.. Spoke to LG earlier about my discoveries with the Automatic Screen Timeout " issue " and they said they would pass this information on to their Relevant Department to test this THEORY..

Still can't figure out whether there was some sarcasm coming back from them.. :confused:

Hmm.. I better not hold my breath - I might pass out ! :)
[LG Optimus 2x] tdci100:
The automatic screen timeout thing kinda worked for me for a couple of weeks, but now, the phone BSOD or reboot around once every day.

I've tried registering the phone at LG VIP Service (I'm in Belgium), but after two attempts, I'm not receiving any confirmation emails, which I got for my two previous (not refurbished) units. So this tells me that my third unit obtained through VIP service is a refurbished one (IMEI already registered in their DB).

I'm about to send an email to LG Belgium, asking for a refund. I expect a smartphone to be up at all time. I don't know how many calls I have missed in 3 months.

I'll make sure to mention "Test-Achats" (belgian consumer protection association)..

If they refuse to proceed, I'll ask my lawyer to write the claim for me, and threaten of legal action. I'm surprised no class action has emerged yet from this debacle.

So class-action anyone ? Aren't you tired of LG bull**** about the supposedly updates. This is a hardware problem, at several levels. It's faulty Tegra chipsets.

As with previous Dell case (XPS with faulty nvidia GPU), it's always hard for a company to admit fault, while the issue comes from a third vendor fault.
[LG Optimus 2x] Vertigood:
Ok, so I installed LauncherPro again, the thing that seemed to cause more bsod's than usually. Today the phone rebooted twice and bsod within 5-10 minutes :(

Uninstalled LauncherPro and it has worked fine since. How come the phone can't seem to handle LauncherPro?? It must be the cause for those bsod's. Sure at this time I did install some other app. A kid animal sound app that I uninstalled right away.
[LG Optimus 2x] bodmark:
Must admit - I've not tried LauncherPro.. let's see if I have the same trouble.
[LG Optimus 2x] geistio:
Here's another workaround for people experiencing BSOD's on CM7:

Since I've disabled both GPS and automatic date&time setting (Settings->Date&time->Automatic) on my phone I've not had a single BSOD.

I am not quite sure, but I think that the automatic date&time setting might actually cause the BSOD's on my phone.

That means that I have to further test my device and I will eventually re-enable GPS, as soon as I am sure, that my device is 100% stable...
[LG Optimus 2x] mas2112:
After updating to V10C using the LG updater tool, the random reboots seemed to have gone away. I set the screen timeout back to 60s to see if all the problems go away. However, I still got BSOD, where I had to pull the battery.

I have experienced 2 types of BSOD:

Screen is black, but the backlight is on, and all four capacitive touch buttons are on. This happened while unplugged from charger (screen timeout set to 60s).

Screen is off, buttons are off, phone does not respond to anything other than a battery pull. This happened overnight while the phone was plugged into the USB charger, and it was warm (also screen timeout set to 60s). After I pulled the battery and rebooted, the phone showed 80% charge, even though it was plugged in all night.

I have also experienced a situation where I had to reboot the phone in order for it to connect to the cell network.

I have also experienced a couple of random times where I had to give my SIM pin, even though the phone did not reboot. I confirmed this by looking into the "Bootlog Uptime" app I installed.
[LG Optimus 2x] chester_go:
You might have found the solution for mine. Testing for 2 hours now and no BSODs yet (it's a first)
[LG Optimus 2x] Opius90:
I installed the original rom found on XDA, with the following instructions. and my BSOD and restart problem was solved. My O2X has been powered on for a week now without any problems.
[LG Optimus 2x] Pwinsesse:
It works!

On a danish cell phone forum theres someone who told they had swiched the includede batterycharger with another one - I have tried that and that was a succes too. I now use the one from my SE Mini, it has a lower outpot voltage (I don´t know if that's the right word) than the one from LG.

One wrote also about charging through a USB-hub, it should also work. I haven't tried it myself though.

I have activated the screen timeout again and it still works.

After the update and the new charger I have had no problems at all
[LG Optimus 2x] bodmark:
...well I wasn't expecting that! My delicate little O2X went crazy, it's EXTREMELY unstable with LauncherPro installed. What is going on there?
[LG Optimus 2x] pulsation:
Strange, I am using launcher pro at the moment too, my phone does not shut down more than once a day these days. Anyway, looks like disabling automatic clock sync and using the clock sync app to use NTP at boot instead helped quite a bit anyway.
[LG Optimus 2x] Pyrolyser:
I experience only random, sporadic reboots. Just noticed one this week but the big issue remains the extremely high temperatures the phone reaches whilst charging, leading to some shut downs.
[LG Optimus 2x] xmoo:
This morning 2 am, 2 BSODS and 10mins ago a reboot :S
[LG Optimus 2x] bodmark:
?!?

Why do these reboots and shutdowns only happen when the phone is in a standby (screen off) state?

What exactly is happening,? Is the power too low and can't cope with too much going on in the background?

I tried using the LauncherPro for further assessment, with screen on constantly, and not one problem (for 36 hours now anyway)!

Just wish I knew what was going on in my little O2X brain when it's sleeping.
[LG Optimus 2x] bodmark:
..yes you're right about the high temperature the phone can reach, but not only while charging.

I have witnessed reboots from temps as low as 26. While in my pocket temperatures have soared to 43 c upon hearing the reboot sound.

conflicting this being the sole reason for shutdowns is the fact I've used the phone at theses high temps (42c) continually for hours while using the phone (with screen on) and its quite happy,noreboots or shutdowns.

but if you then ask the phone to then continue in idle (screen off) it just can't cope

Definitely a stability issue in idle.

even when making a call -if you end up having a conversation that's longer in duration than your screens timeout setting -the chances are you'll end up with a black screen!

Does anyone else notice the phone gets hot around the camera lense? Is this where the tegra processor lies?
[LG Optimus 2x] EbiEre:
Hi guys,

i got my 2x last Monday and heard about this issues before. I will shortly report what happened with my phone:

Got it Monday, after some time in the charger i tried to turn it on, nothing, bsod. Battery pulled and thought, ok , the bsod exists ;)

Next step was to root and put a custom rom on it. Tried Modaco, Cyanogen and JM Cyanbread. Most happy i was with cyanbread. I read in this thread that i should try to shut off the screen manually. And this worked... at the beginning ;)

Today i made a Nandroid backup and flashed the vorkkernel, since then the phone was unstable, had one shut off and after some hours it was off, but i could restart it without pulling the battery, but i got a bootloop at the Lg Symbol. After that i restored my backup , but some minutes ago: again the bsod, had to pull battery and it had 20% lower battery.

But like you guys say it seems to be the idle mode, when the screen is off.

Is it possible to do a logcat or something like this? I can't believe that no dev has a solution for the problem, if it is a software problem :(

Thats one big point why i think to change the device.. the other point is the screen bleeding, but the reboots / bsod's are mor annoying ;)

Ok the post is a little longer than i expected lol Sorry for that :)
[LG Optimus 2x] Tangkapan:
My Phone is rumming now 93 hrs without reboot or BSOD.

Using V10C Froyo Android 2.2.2 German Version

I used Quicksettings to disable Screen time out, but somehow during phonecalls the schreen timeout still is enabled. But without the BSOD. it comes right up again. Using a different Charger too.

The only thing that bothers me is the battery usage during WiFi and phone calls.

Otherwise when i put BT and WiFi off and use it as palyer for audio books . it lasts the whole night and still 55% battery left.

I really hope those things get fixed with new ROM GB.
[LG Optimus 2x] frittenpiekse:
@Tangkapan: during phone-calls, the lightsensor switches off the display as long as you hold your phone to your head, that has nothing to do with the regular display-timeout ;)
[LG Optimus 2x] Tangkapan:
Thanks for the hint.. but it although shuts off during freehands via bluetooth.

Plus i think that the Lockscreen is a small factor too. If you re using your battery untill empty and shut down, recharge it to about 40% the Lockscreen is hanging and it took 20 try's to unlock..

i will change that Lockscreen and report later..
[LG Optimus 2x] frittenpiekse:
ok then maybe general during phone-calls, never realized it while using bluetooth cause it's in my pocket then ^^
[LG Optimus 2x] Vertigood:
With screentimeout disabled I had over 80 hours of uptime, but then i got a bsod :( Been running normal since yesterday afternoon.
[LG Optimus 2x] bodmark:
When and how were you using phone when you got the bsod?
[LG Optimus 2x] Vertigood:
Screen was off..Had it in my pocket. Picked it up just to check if it was still running. Battery was still at the same percentage when I turned it back on.

No problems today.
[LG Optimus 2x] EbiEre:
Short question:

What is LG saying to the Bsod Problem? Did they ever give a feedback to this?

Cheers
[LG Optimus 2x] Vertigood:
No real official feedback that I know of. But that they are aware of the problem with some units and are working on a fix. They have been saying "two weeks" for months now :)
[LG Optimus 2x] neovdr:
On CM7 RC1 there are no random reboots. If you delve into the nightlies you risk more though!
