Not so, my O2X running CM7 RC1 shut off mid-phone call last night, battery was just under 50% and had plenty of life. I continued the call after rebooting it ;)

However.. it could be related to the baseband and RIL I'm running, which are both 0502
[LG Optimus 2x] getexsm:
Came here to read about rooting and modding for my Lg2x, and found this huge thread.

Same problem here.

Android 2.2.2

Baseband version: 1035.21_20110405

Kernel version: 2.6.32.9

Build: FR83G

LGE version LGP990-v10b

was out jogging with gps and attached to my hip so got really hot, bot no problems there, after that i did charge it to 100%, and when i did pull it our from the charger it did 2 reboots after each other.. super strange. did Nothing.

went to sleep with 100% and 22:00, and woke up 05:30 by my own means, and the cell was dead! 0% battery.. with sync off, no background apps or anything.

Not rooted, want to but if this occur again i will replace it (Again, first one had bad speaker)

so, Hope LG is reading huge threads like this.. Thinking of refound and switching phone to HTC.. expensive but i know they usually work :)

If you can get rid of it then do ASAP, I got rid of mine after 3 months, one of which was wasted in and out of lg service.

Got a galaxy s ii now and couldn't be happier.
[LG Optimus 2x] mas2112:
I installed CM7 (nightly 78) a few days ago, and I have not yet seen the same random reboots during charging and BSOD. This makes me think that this problem is software, rather than hardware. I've looked through the Motorola Atrix forums, and I did't see persistent reports of this problem (so probably not a Tegra 2 issue).

However, my phone did crash a few times, but that's probably because I'm using a nightly build.

On a side note, I noticed the price of this phone has crashed, as deserved. The lowest price I've seen was 320€, compare that to 490€ for Samsung Galaxy SII. Assuming LG gets their act together and finally gets their firmware stable, this is a great deal. Although, I would never recommend this phone to a friend who isn't into the technical stuff.
[LG Optimus 2x] K2010:
V10C was good for me

tried the firmware at http://xdaforums.com/show....php?t=1035041

BIN_LGP990AT-00-V10c-525-05-JUN-28-2011+0 from STARHUB

sofar good, LG Optimus 2x has not rebooted or reset, temperature doesnt feel as hot/warm as before update from V10B

I used the update procedure by Paul with smartflash using firmware starhub V10c

backed up all my data with Titanium backup and contacts with Yahoo mail.

got all my data restored except for SMS.

sofar good results.

no reboots and the battery doesnt overheat, infact the battery temperature is at a constant 23 degrees celsius now. Not sure if this is accurate as the temperature does increase just not a warm as it used to be before the V10C update.

measured with various battery monitoring software. eg Battery Monitor 3 - Ohanasiha corp ver 3.3, Elixir 1.12.2

Happy with V10C :D
[LG Optimus 2x] chong81:
My friend bought a new O2x set (set produced in May) and it is consistently freezing/shutting down while charging, with the back getting very hot.

Latest firmware V10d. Sigh.
[LG Optimus 2x] d4m4n:
I wonder if it would work with a charger that gives only 0.5A.
[LG Optimus 2x] amateru:
When I updated my O2X to baseband 22.06.11 (v10d) it did freeze from charging once and reboot once.. but after that, my phone magically removes all this headaches.. didn't do anything special on my part.. so I couldn't give any suggestions.. but maybe the phone just needs to iron things out for awhile after update?
[LG Optimus 2x] nold-i-spolen:
Several Danish carrier have decided to give the customers there money back if they still have problems with the O2X after the latest software update.

Google translate page:

http://translate.google.com/transla...bage-for-din-lg-optimus-2x,lid.16343/&act=url

Finally this nightmare is over! I think i'm going for a SGSII........
[LG Optimus 2x] chong81:
I've swapped the charger and battery to my set, and no problems, so it had to be something in the handset.

Then I recalled that the phone was charged twice on the original V10b without issues. V10d was what the LG updater updated it to.

So I flashed to V10b from the xda original rom thread, and this time it charged the battery (mV goes up), but the battery % did not move! Only a reboot fixed the stuck battery %.

As a last resort, I hard reset, and it hung at a black screen afterwards! I hard reset again, flashed it to Singtel V10a (which I knew worked fine on my own set), hard reset, and then to V10d again via LG updater. Now, the first charge from 29% seems to have gone well for the past hour - it's at 90% and still going.

So my ordeal tells me the firmware flashing process is not reliable on the O2x. I'd suggest you guys to reflash the firmware if you are seeing freezes/shutdown during charge on your sets.
[LG Optimus 2x] bryant_16:
How does this unresponsive situation work?? Is it the screen got nothing but when you press on it, the capacitive buttons will like up? So how to recover it? Pressing power and volume buttons together for how long??
[LG Optimus 2x] MeX_DK:
The screen just remains solid black, the captivate keys remains all unlit and its more or less a hit or miss approach to wake it up >_<. Can't say how many times you need to press exactly as it varies on the situation.
[LG Optimus 2x] bryant_16:
For my case is screen remains solid black and the captivate keys will light up when I touch on the screen. Is it hardware issue or a software issue?
[LG Optimus 2x] mould14:
rebooted twice yesterday ( day 4 ), from Hong Kong

Android: 2.2.2

Baseband: 1035.21_20110218

Kernel: 2.6.32.9

Build:FRG83G

LGE-Version: LGP990-V10a
[LG Optimus 2x] ULJ:
The thing I see is that the baseband version is older than on mine (1035.21_20110223). So you could making a backup with clockworkmod recovery, then flash the new baseband software (look here: http://xdaforums.com/showthread.php?t=1007825) and then restore you backup. You will then have updated the baseband software.

Don't know if that has any difference but give it a shot ;)
[LG Optimus 2x] MeX_DK:
Updating my baseband at least stopped my LG 2x from rebooting when charging and from shutting down.
[LG Optimus 2x] xmoo:
I'ma wait till 2.3 and if that still doesn't fix it, I'ma root my phone.

I've promised myself not to root jailbreak hspl anymore :P
[LG Optimus 2x] bryant_16:
Erm.. I'm in Singapore, can I update the baseband too?
[LG Optimus 2x] xmoo:
Everybody can as long as you have the same model number.
[LG Optimus 2x] bryant_16:
The model number you referring is P990?
[LG Optimus 2x] xmoo:
Yes, that is correct.
[LG Optimus 2x] ryaneu:
Can someone confirm whether this auto shutdown/reboot issue is just a software issue? Hope it can be fixed in future software updates.

I saw that Nexus S has similar problem but fixed by software update.
[LG Optimus 2x] MeX_DK:
Didn't have any auto reboots in a while after I flashed my radio. But this night it had a fit again.

So sadly its not a fix that works, now its only remains to be seen if the number of reboots it does is reduced or it just returns to the same amount as before >_<
[LG Optimus 2x] magjz:
what I'm wondering about is the fact that only a few people seem to have that problem. and the 'optimus speed' isn't that long available ... so we don't have so many baseband versions that this could be the reason. could it be possible that a hardware problem may cause this issue?
[LG Optimus 2x] DeadmanINC:
getting mine tomorrow hopefully nothing goes wrong about the set heh

not yet rooted

from Hong Kong

didn't encounter this reset problem(i hv installed some apps that would appear when bootup, thus i know there is no reboot)

but the touch screen seems odd and uncontrollable last night when I played about 2hours, guess it was overheated?????

Keep us updated too! Singaporean user here too!
[LG Optimus 2x] Elf89:
Hi! I'm trying to understand this problem's causes. How many of you have experienced it and removed f-secure and car kit? Removing theese could fix the problem?
[LG Optimus 2x] reidar.ostrem:
Sadly to report that I have had spontaneous reboots and lockups after thinking that my phone did not have the problem.

I did remove almost all LG software within the first 30 minutes of use, and still got the problems after 3 days of use..

I upgraded my baseband yesterday and have not experienced anything yet, but we'll see.
[LG Optimus 2x] Elf89:
I red some posts and this issue is totally random! Another idea: SD card presence?
[LG Optimus 2x] xIceCream:
Umm.. To be honest, i NEVER EVER faced a reboot or shut down issues on stock ROM, only hang, all i do is just lock the phone ( pressing power button ) and unlock it, it may take awhile, then problem solved.

I only had one shut down situation during installing an app, i was in hurry and i quickly press all the home button, back button and the power button. Lol. So it hung, and reboots.

I think im one of those some lucky person who never face those problems !

Cheers,

xIC
[LG Optimus 2x] Vertigood:
So, I have not been using my memorycard for a while and been having some bsod's. Have set the screen to never timeout which worked good for about three days then the first bsod after that came. Then none for a couple of days again.

2 days ago I inserted my memorycard again. Today the phone rebooted once and bsod within 20 minutes or so. Did nothing out of the ordinary with it at the time. Took the memorycard out and has not suffered a bsod since.

I can live with a bsod every three days but not several a day. Can the memorycard actually cause more bsod and reboots? I wonder.
[LG Optimus 2x] BTW lover:
Funny thing I noticed today:

I used to have lots of hanging, random off and stuff when charging, but after I started using CM those disaapeared. I also haven't used the charger that came with the phone for quite a while, but instead used my wife's SE chager. For a few days I used the LG charger again and had three freezes during charging, phone beeing all hot and stuff.

I checked both chargers and the LG one has 1000mA (1A) and the SE one has 850mA. I guess that the phone just pulls to much juice to quickly for the battery to digest. I noticed that the LG charger seems to charge the phone a lot faster than the SE one, so maybe this is where the trouble comes from.
[LG Optimus 2x] chester_go:
+1. Been charging with the stock LG charger connected to a USB hub with LEDs before the USB cable. No BSODs at all.
[LG Optimus 2x] victorpak:
BSOD are gone from my O2X: here's how

First of all:

1) My O2X only BSOD when its screen is off. NEVER when the screen is on. It used to happen quite frequently, at least 2-3 days/week.

2) I don't have random restarts in my device.

3) I don't have problems while charging if the screen is kept on

I think the problem in MY device was abnormal "sleeping" behaviour.

A previous workaround I used was keeping the screen always on, locking my LG O2X and putting it in my pocket. Not an ideal solution, I had to deal with heavy battery drain. No BSODs ocurred this way.

Another workaround I tried previously was playing a music in the background with silent media volume so I could turn the screen off, which wasn't all that practical too; it did worked for the time I used it.

My solution (2 weeks and counting):

There's a free APP in the market that solved my problems (actually a previous version came in my custom ROM) called LG 2X/Black Notifications.

https://market.android.com/details?...2xtouchlednotifications&feature=search_result

The app uses pulsing led from the bottom touch buttons to tell if there are new SMS/missed calls/e-mail etc. while the screen is off.

While the app itself is great, it did something better for me: it cured my device from BSOD.

It kept my device from entering the BSOD state of "abnormal sleeping" while the LEDs are pulsing. I sent myself a SMS that I keep unread to trigger the notification and use a widget to read new SMS.

If your device problem is the same as mine, chances are that it will work for you too. Let me hear if it did or didn't work.

Maybe we should contact the developer (are you reading?) and ask for an option to keep the LEDs pulsing even without notification.

Ps: Gingerbread users need a rooted device to use the app.
[LG Optimus 2x] jacktheonlypirate:
That's a really nice app...thanks for sharing !!
[LG Optimus 2x] legolittlebrick:
Hi all!

Yesterday my new O2X has finally arrived with 10b stock rom. It had the same problems, i put it in standby e some minutes later, when try to wake it up it was power off and needed to power it on again. Every time.

I try to update to 10c stock rom via OTA. It was late night so i didn't made al lot of tests but it seems that the problem has been resolved.

Now I have some questions:

1) Is there any tests I can do to check if the problems are really gone away?

2) If the problems are really solved, should I send it back to the seller anyway?

Sorry for my bad English, i hope you can understand :)
[LG Optimus 2x] xmoo:
Just enable the clock app and put it on charge... Uptime for about 400+ hours now....
[LG Optimus 2x] cartoonistas:
I would like to report that i had my first Freeze with the new update that LG released . (while I was Talking My Phone Frozed) .So FYI , the v10c Italian - Greek, Does not solved the reboot Freeze isues.
[LG Optimus 2x] d4m4n:
I bought a used 4 month old Optimus 2x. It had freezing, reboots and BSOD when new. The original owner got it repaired for warranty. The main PCB was changed.

SO I guess there are also hardware problems that can be fixed.

No problems for 4 days after I bought this. I always charge over night and had no reboots.
[LG Optimus 2x] tdci100:
I'm in Belgium. I'm on my third unit.

The two previous units were overheating and rebooting/freezing/whatever mostly on charge.

The third one rarely had problems on charge (I kept the battery and charger from the second unit), mainly some BSOD and reboots while not on charge (though it happened sometimes during the night, on charge).

I've tried original ROM (v10b), Modaco and CM7. Modaco was the most stable of all, but still had some reboots every now and then (could go a week without issue). CM7 was rebooting and overheating like crazy (5-8 freeze a day). Original ROM was having issue once or twice a day.

I recently contacted LG for a refund, and the representative said the update for Belgium was to be expected within 2 weeks (to which I said "riiight"). I check later that day to find no update available (I was on radio 20110405).

4 days ago, I check again, and an update was available.

It sent me to V10C and radio 20110622.

I immediately rooted and went to CM7.

It's been 4 days now, the phone is very fast and no crash, reboot, BSOD so far. CM7 is a real pleasure to use.

So I guess it may be a hardware issue for some units, and radio issues for some others. And a mix of those for very unlucky owners.

Will report again in a week or so. But if LG comes back and offer a refund, I'll still take it and go back to HTC.
[LG Optimus 2x] d4m4n:
I bought a second hand Optimus 2x. First owner had shut downs during charging and network dropouts. The phone was serviced for warranty and the main PCB was changed. No problems since then. I have owned this for a week and no FC, BSOD or reboots :)
[LG Optimus 2x] silentmelodies:
I bought mine about 3 weeks ago, and only got to use it for roughly one week.

First week it worked fine, then and the 7th day it went completely dead after I took out the battery after freezing once after a random reboot when I was charging. Couldn't do definitely anything to it, so took it over to the service center after 4 days (I was very busy). They fixed it right away there in about an hour and they told me it was a power issue, blaming me for using it while it was charging. I didn't lose any data so I was fine with that.

After ONLY 2 days of using it again, it went completely dead again. Was playing DD, freezed and waited for 5 minutes. Took out the battery for a restart and got stuck at the startup screen for some great minutes. Couldn't wait more and took out the battery once again, - phone dies. Sent the phone again, and they told me they had to replace the whole chipset. (why not just give me a new phone, duh) And this time they tell me it was because I installed some random incompatible game.

Now if it isn't me who's too stupid installing Dungeon Defenders to a Tegra 2 phone, or them for blaming me things for a faulty phone, I dont know who else is.

The phone itself is great, but the fact that the phone is faulty and them not admitting it annoys me :mad:

- plus I have to wait some great 5 days until I can take the phone back :(
[LG Optimus 2x] rottenpenguin:
But what about the battery? Won't this app drain the battery if it keeps those LED buttons on? And what about the screen? Does it enter stand by? Because if not, the screen will surely deplete your battery within two hours.
[LG Optimus 2x] bugxyz:
Hello.

I'm new with Lg o2x (57 days) but I have found a combination that fix this problem (it works for me).

I'm using original rom:

BaseBand 1035.21_20110622

Kernel 2.6.32.9

Build FRG83G

Version V10c.

At the begining I had a different baseband and version V10b and a lots of black screens and phone off almost at each charging.

After rom update it was better, no phone off but random black screen again there.

After that I have done next steps:

1. I have done the tricks from : http://xdaforums.com/showthread.php?t=1170146&highlight=rocket

2. installed the LG 02x/black notification and configured in normal mode (only to have notification on missed calls, messages,emails and on charging);

3. Replaced LG Home with Laucher Pro.

4. Installed Blade Wifi Fix (no wifi error after this).

What I can add is that I have all the time an 2G data conneaction active (only when needed switch to 3G) for sync and weather/news update.

Since two weeks I have no problems, battery consumption good (50 to 60 hours).

Hope this helps you regarding this problem.

Oh this is amusing. A review of the Optimus 2X retweeted by LGbloguk on twitter

http://www.landofdroid.com/2011/lg-p990-optimus-2x-review/

I loved the part where they say one annoyance was the phone overheating when charging resulting in them having to remove the battery

LGs response was it wasn't a known fault and was limited to that handset they were issued.........

Bull****!!!!!!. They should take a look on here
[LG Optimus 2x] susnoduadjii:
the software from lg is very unstable

is the new build of lg(june-july) still have this problem

my friend buy at feb it has same problem
[LG Optimus 2x] Vertigood:
Since I took out the sdcard again my phone has been rather stable. It crashed once during a call (first time). And I rebooted manually once. It doesn't get warm like before.

I have no screen timeout

Disabled lockscreen

Gonna try formatting the sdcard and try it again just to see what happens.
[LG Optimus 2x] legolittlebrick:
I tried almost everything I read on this forum but the BSOD will always come back, it's obviously an hardware issue. Mine is actually in LG assistance and I'm waiting for it...
[LG Optimus 2x] Gaba90:
i had that too, but i flashed to modaco rom and the problem was solved..
[LG Optimus 2x] legolittlebrick:
Using e specific ROM can't be a definitive solution...

BTW I tried many roms CM included and the random BSOD are still there
[LG Optimus 2x] XL3N7:
I tried various roms, modaco included, all basebands and the problem was always there. The phone would always shut off on the charger or "intensive usage" like playing a game, talking on the phone for more than a couple of minutes or browsing the web for a while. I have sent it back and now I'm trying to get a sensation or a galaxy s 2 instead of a replacement 2x.
[LG Optimus 2x] d4m4n:
Get it serviced for warranty. I bought a used one that had problems. The main pcb was replaced in warranty and I've had only two reboots in two weeks. Before the service the phone had BSOD and reboots during charging.
[LG Optimus 2x] fongfc:
I belived it's a hardware issue. My first unit got BSOD frequently but it never happen on my second unit.
[LG Optimus 2x] gasgasgas:
For miui:

after solving some of the problems that comes from the confusion between the internal and external storage (with the internal sd mod) i still had shut offs.

Some user suggested an app (LG 2x/Black notifications) that pipes all the notifications that would light on the led and makes the buttons flash instead (since we don't have it).

I sent myself a message and after receiving it some alerts were triggered that told me stuff about granting permission to some apps related to sms.I had three notifications: LG 2x/Black notifications, Android Notifier and one that tells how much weekly data I have left.

I checked the flag "remember" and clicked allow. The message disappears after some seconds if you don't interact.All those three apps need to access sms related things, LG 2x and Android notifier needs them because they notify you in different ways after you receive an sms, the data counter widget needs it because that is how it receives stats from my provider about data left.

No more shut offs for know, could be just luck is too early to say it for sure.
[LG Optimus 2x] bodmark:
In my opinion, it seems that anything that prevents the Phone from SLEEPING (Idle State) seems to resolve this issue of BSOD and reboots.

After further investigation, Disabling the screen timeout WILL stop these problems; but I can't get more than 8 Hours of battery usage this way. I've tried reducing the brightness to bare minimum, used various screen savers which just reduce screen to lowest brightness level.. but all those measures weren't practicable..

I can understand how the LG 2X / Black notifications app would work as it prevents the phone from SLEEPING.

I have also found a few others, of which I now use :

POCKET SENSOR (which is a very Usefull App too )

EASY PROFILES (using the Rules settings, as this also constantly monitors for changes in Status, Location..also allows me to optimise battery saving conditions and features and adjust various settings)

Finally, SCREEN OFF FX to switch the screen off when the phone is not in my pocket ( to save the battery drain from the screen being on unnecessarily )

These 3 Apps prevent me from experiencing the BSOD and constantly removing my Battery cover (it's not a secure as it used to be...)

I manage to get a Full Day of Casual use out of my phone with these Apps; which is not Brilliant, but acceptable for me.

If any of you decide to use these Apps, remember to Disable the Screen time out . set to NEVER in the Easy Profiles Settings and also disable the (Crappy LG ) Lock screen.

I'd be interested to know of any further Apps anyone has discovered which prevent the phone from Sleeping. Especially ones which don't consume much juice from the already lame battery which comes with this phone.

Thank You Once again for this invaluable and informative community..

.. where would we be without it ...

I for one, am glad there are some people out there that care about this annoying issue... as LG certainly DON'T .
[LG Optimus 2x] .:george:.:
My BSOD problem stopped when I updated to 622 BB+RIL, wiped cache and installed latest cm nightly at the time. I have been running without BSOD for 2 or 3 weeks now :)
