What about reboots?

Hi everyone,

I'm old/expert in linux on x86, but just started in embedded.

Using a P990 (shipped with V10d) for 1 month. I switched last weekend to CM 7.1 RC1.

After flashing, I started configuring and installing apps from market (all on WiFi), getting to around 5% battery. Put the phone to charge and in the morning, power button was not responding. At the time I did not try to connect it to PC (this hit me only while going to work), so I just got the battery out (just to cut contact) and reassembled the phone. It started instantly (so no x seconds waiting).

During following 3-4 chargings (all except 1 were during the whole night), this never happened.

However, on one of the mornings, after getting it off the charger, I wanted to install something from the market and reactivated the WiFi...the phone started lagging and after 10-15s rebooted (note, not poweroff). I remember this happening with the V10d SW as well once, while it was on the desk, but I don't remember WiFi state (but certainly not connected to AP). Also I've experimented some wifi activations issues, again with lag, but after 5 attempts it activated. I've had this happen to my previous HTC Legend, but that always resulted in reboot (even loops).

So I'm wondering whether this could also go with the general handling of WiFi on Android. As a note, this usually happens when wifi signal is low.

PS: I usually keep wifi off, but I will charge it with wifi on this night.

If I have the "power on does not wake screen" symptom and adb is working, what/how should I try to debug?
[LG Optimus 2x] mathew7:
Suspicion confirmed:

Phone had shut down just about 2 hours after last screen off. Morning power on, button not working.

Why 2 hours? I remember checking the phone at 23:38, and after restarting it, I saw battery monitor having the last history at 1:43 (5 minute update rate).

Also I have attached my battery monitor widget history (of course I left only since 20:00 last night). I see the battery itself had low temps, but since the last report it could have gone high due to wifi issues (so don't exclude temp issues).

I saw recomendations to use pastebin, but I just don't have time now to do it (signup for new account).

Maybe in next week-end I will test other scenarios.

PS: After battery pull solving, when I connected to PC to get the history file, I got the 10s no power button waking, and I don't know if it woke because I held it for more than 2s (like power on) or because the USB notifications appeared.
[LG Optimus 2x] massari90:
Well i got my phone the other day. I straight away flashed CM7, and while installing apps (and plugged into charger) I had like 3 rebots. However since then, the phone has been fine. Uptime of 20 hours.. It was plugged in charger overnight and everything.. battery drain is awesome so far. I guess I will give it a few weeks to see what the deal is with the reboot issue. I am just hoping it doesnt happen alot as I need my alarm to wake up haah
[LG Optimus 2x] mas2112:
I flashed to the V10C Stock ROM, where I had the reboot problems. So I rooted and installed CM7 Nighlty 78. And it was much more stable. My uptime was consistently in the range of 2 days. Crashes would only happen after phone calls. Then I flashed to Nightly 101, and it seems the crashes during the phone calls have gone away. The uptime is 3 days and counting. It runs much better than stock ROM.
[LG Optimus 2x] komedol:
I had the same problem yesterday. Strangely, it happened after I applied the r1 stock performance pack (I'm running on stock rooted froyo 10a). Luckily I made a backup through CWM. Restore, and now it's back to normal :-)
[LG Optimus 2x] ThaRagnarok:
First of all, everything is stock version on my phone.

Android version: 2.2.2

Baseband version: 2.6.32.9

Build number: FRG83G

LGE Version: LGP990-V10d

When I started noticing the BSOD's I discovered this forum and started implementing the tips (without using custom firmware, I'd like to refrain from that until I have no other choice).

Anyway, I used the app "mySettings" and set the sleep-interval to never. This has drastically reduced the number of BSOD's (from mutiple times a day to almost never).

However, one day I was laying in the sun, phone in the shade and it started rebooting, having BSOD's etc (every minute or so!). This made me think it was part a hardware problem after all (overheating), but I did always manually set it to sleep.

So I tried exposing the phone to full sunlight, without (using powerbutton) letting it sleep. After 15 minutes, in the heat of the sun, it was still working flawlessly,I put it in the shade again, put it to sleep, tried a minute later... Reboot. :confused:

Furthermore, I would like to ask who of you had the following problem:

After the Neversleep "fix", people started calling my girlfriend saying I didn't answer my messages or pick up my phone. So I tried texting (with another cell) to my Optimus phone and the text was "sent", but it never arrived at my Optimus phone. I rebooted the Optimus phone, no new messages. But when I text-ed again, after the reboot, that message did arrive.

So, did your incoming messages ever go up in smoke?
[LG Optimus 2x] bodmark:
... I also experienced the incident you had with the phone rebooting while it was left outside in the Sun, almost identically to the way you described it.

... I still can't figure out whether the phone gets Hot AFTER the BSOD has happened, and this is a consequence; Or the phone getting HOT causes these reboots / BSOD (although these then only happen when phone is in Idle.

... Have since discovered that manually switching the phone off, with the off button, even though the sereen timeout is set to NEVER, DOESN'T prevent All BSOD's and reboots. Though having written in a previous post suggesting this, i went almost 3 weeks at one time without problems.

... I now use these 3 Apps:

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 )

Using these prevents my phone from Sleeping and I NEVER need to use the Top OFF button to switch the screen off anymore.

The apps I suggest do have free trial versions.. so perhaps you should give them a try.

Remember to keep automatic screen timeout to NEVER . And Disable the LG screen lock (though Pocket Sensor will do this for you).

As for you last query, I have experienced delayed Texts and calls not coming through in the past, though I can't say whether they are related to the reboots , BSOD's, seperate problems or Network issues.

Not experienced Any for a while.
[LG Optimus 2x] massari90:
Well I am talking to warrenty on monday. Got this phone from hong kong but looks like LG Australia will cover it. Will verify monday :D And hopefully the new phone wont be restarting. I have reboots every hour :( And massive battery drains sighhh! Might have to go back to E71
[LG Optimus 2x] tomsi91:
I have bought O 2x before 5 days. I use it all time. charge twice a day. browse net, play full hd movies over hdmi. btw. little disapointed, it can play only low profile coded full hd, so every full hd video must be transcoded before use in O 2x (galaxy s ii can play high profile.). tried cyanogen mod 7 for one day. and no restart, rock stable. with go launcher ex very fast. browse with opera mobile with no lag, all absolutely smooth. no problem. i only found some bugs in lg firmware, but nothing horible. so i can only recommed. for the money it costs, its best buy, you can do. much more nice and cheap than galaxy s ii.

i have czech republic firmware.
[LG Optimus 2x] massari90:
Okay update.

I decided to go flash stock rom for Australia before sending to warrenty. However since it was the weekend I decided to trial it. I have had it for 19 hours so far uptime and NO reboots. I have charged it, used it as GPS in the car for 2 hours, and charged again. I will leaev thsi for a few more days. Really dont understand what is going on..

10C Australia stock rom however, flashed using the smart tool thing
[LG Optimus 2x] Vertigood:
So, today my optimus 2x got unusable.

I can't shut it off with the on/off button. And can't even close the screen you know. After I take out the battery and reinsert it, the phone starts right away without me pressing any button. So it seems the button is stuck. Not the actual button, cause I can still press it like normal.

So I wont be using it and gonna send it in for repairs. Yesterday I got a numerous bsod and some reboots. More than I am used to :(
[LG Optimus 2x] gregor40:
Got the phone for 2 weeks now.

Everything is stock:

Android 2.2.2

Baseband 1035.21_20110405

Kernel 2.6.32.9-dirty (?)

Build number: FRG83G

LGE Version: LGP990-V10c

Had maybe 2 reboots of the phone. One was BSOD, had to remove batt and second time was a reboot -when I woke the phone it asked for PIN.

Maybe I am lucky?
[LG Optimus 2x] ULJ:
Update the phone to V10D.
[LG Optimus 2x] LecterMe:
Just got my first BSOD after 2 months.

I have been using my HTC charger all the time and flashed CM7 first day and have never had any problems with the phone.

10 minuttes ago I unpacked the LG usb cable and connected the computer to the phone....... Instant BSOD !!
[LG Optimus 2x] davew:
So I got a brand new P990 from Amazon for the bargain price of £299. It was the best cheapest phone I could get.

To cut a long story short I only get BSODs when the phone is in a leather case that I bought for it and/or when I've forgotten to turn off the wifi.

I wonder if the case is too tight and presses down on the volume rocker?
[LG Optimus 2x] Escobarretje:
After my update to v10D I've got much more random reboots & lockups than before. Only got 2 in a month with v10C or before. Now around 2 A DAY!!!

I hate this, phone can't be used normally now. They say GB is coming in 2 / 3 weeks and fixes the problem, I hope so...
[LG Optimus 2x] davew:
Over last night and this morning the phone behaved absolutely perfectly, but then a short while ago I left the wifi on and manually put the phone to sleep, within 15 minutes it rebooted spontaneously. Since then, I've had another random reboot and two BSODs. I only got this phone yesterday afternoon and I'm feeling pretty bitter. Amazon and Expansys have slashed the price on the P990 because the phone is a lemon!
[LG Optimus 2x] neilpenn:
Mine phone was also doing the same. I contacted t-mobile and they were telling me that they have had a lot of complaints regarding this. I had a replacement sent out and I haven't had that issue come back. However, I was running 2.2 rooted and now that I got my replacement I have 2.3 and cannot easily root my phone unless I change version software and more...:mad:
[LG Optimus 2x] davew:
I'm not totally following you, but from your description I guess you have an american G2x, and the replacement has gingerbread on it rather than froyo. Would that be right?

We're still waiting for gingerbread over here in Europe for our O2x's unfortunately, no idea if its going to fix our problems either :-(
[LG Optimus 2x] Vertigood:
So, after letting the phone be for a day or two I put the battery back in to see if it started automatically like before. But it didn't, and there was an update (V10d). Updated but got an bsod just a while after.

It feels faster now though. No lag like I could experiance before. Battery seems to drain even faster now though :( It's sad. I really like the phone..but can't trust it. Guess I never will.
[LG Optimus 2x] aco47:
I started this thread - Now I end it.

Hi All,

When I first started this thread I would never have thought that the count would get this high. Obviously LG made a big mistake with this "smartphone".

My O2X history is now over. I got my unit swapped for a new O2X, but had same problems. After 5 months I were allowed to return it and have now received a SGS2 instead, but on the same contract. Very pleased with this. Only had to pay 100 Euros in difference.

It is sad that so many people have issues with a so expensive phone and I still wonder why LG didn't call it back, instead of claiming to solve the problem with updates that never see the daylight. Still the claime that the O2X has a low faulty percentage, but there are so many people out there with problems, which does nothing about it, and therefore does not count in LG's rating.

Fight for Your replacement unit or even better money back. In Denmark this is now the solution the mobilephone companies offer people having problems with the O2X.

Never more LG for me!

Cheers.
[LG Optimus 2x] davew:
Sounds about right to me. I've had the phone since Thursday, If I even try and use my new phone for anything other than a bit of light texting my uptime is measured in minutes with near constant reboots and lockups every single time it goes to standby. It's a smartphone, not an ornament and I want to use it for something rather more than light texting!

I'm torn now between waiting to see if the Gingerbread update (with new, hopefully bug-fixed Nvidia kernel) will fix these issues, sticking a custom ROM on it to see how that goes or simply packing it off back to Amazon for a refund.

Don't know what to do at all. Gutted.
[LG Optimus 2x] Frejdan:
Another solution would be to install a custom rom like CM7. Honestly don´t understand why people whine about Gingerbread not coming when they have a better alternative just waiting too be flashed.

I can understand that people are upset with the restarts and bsods and if you can trade it in, if you like me were to late to trade it in just flash CM, I haven´t looked back and would not trade my 02x for any phone at the moment.
[LG Optimus 2x] davew:
OK, well there's quite a few reasons why I'm not flashing a custom ROM:-

1. CM7 uses the same kernel as the stock ROM. Drivers and hardware support are in the kernel, so if there's a bugged driver causing these crashes CM7 will crash too. I have heard that Nvidia have provided tegra 2 updates to the next kernel and the offical gingerbread release is the only place you'll get these.

2. CM7 is not at a stable release yet for the O2x. There are still quite a few issues and bugs as far as I have read, like the HDMI out not even working. Other custom ROMs have other bugs.

3. I have no idea if if my problem will be solved by flashing CM7. There are O2x owners who never had a problem with stock, some who never had problems after flashing a custom ROM and there are some who have had problems with both.
[LG Optimus 2x] mas2112:
I'm running CM7 nightly, and there are still a few stability problems, but they are far less frequent than the stock ROM. The maximum uptime I have reached so far with CM7 is 5 days. Far more stable than the stock ROM, which would crash every day. It seems that LG is either incompetent or they just don't care that their flagship phone sucks.

For those of you considering buying this phone because it's cheap, there's a reason it's cheap.
[LG Optimus 2x] sander-m:
This shutdown issue is annoying.

It happens to me everytime I charge my O2X, no matter I use LG or 3rd party charger. But for some reason, the issue seems to be fixed on stock 10d rom. I haven't had a single BSOD for 2 weeks with stock 10D release. But I flashed CM7 build 112 a few days ago and I have the BSOD issue again. So I flashed Thanatos 2.1 (with SwiftExtreme kernel), but the problem remains. Maybe it is an undervolting/power circuit problem? Maybe an updated kernel will help.

I use BB 725 + RIL 725 by the way.

I'm going to flash to stock LG 10d because of this issue. But i really liked the speedy and smooth custom roms.
[LG Optimus 2x] davew:
I smartflashed the v10b UK ROM, and it was infinitely worse - every single time the phone went to standby it froze. With v10d UK, I could get a days uptime but only if I left the phone completely alone - the minute I tried to do anything with it it would crash.

It's back in its box waiting to go back to LG. I've made contact with the service centre here and I'm just waiting for confirmation of whether or not they need the full box and all cables etc. or just the phone + battery.

Fingers crossed I'll get a working phone back under the warranty and won't have to wait too long.
[LG Optimus 2x] fifi139:
i was using mcr fr19 and sometimes it just crashed. but it was a lot better than v10a/b i used to use. Yesterday i just updated to stock rom v10d - bb622 (indonesian version which is similar to s'pore one) and so far it's even more stable than fr19. I can use Sygic for a long time (v11.0.1) and no crash at all. I'm going to try using it while charging it and see if it survives. If so, then I'm gonna keep this stock rom until gingerbread arrives.
[LG Optimus 2x] sander-m:
Stock 10d seems to be stable to me as well. Battery and speed are not bad, but I still want gingerbread on a dualcore phone like this.
[LG Optimus 2x] Curanox:
I had a similar issue.

Out of the blue my wireless stopped to work on the O2X.

Tethering as well as just starting the wlan functions result in blackscreens and restarts.

I do not get a MAC address from the wireless module and wifi fix apps did not work...

Also since that issue my battery drain is astronomic (at best 4hs in standby!)

I tried several different ROMs including stock rom, differnet Kernels, different basebands and did a complete factory reset...

This is quite dissapointing...
[LG Optimus 2x] jacktheonlypirate:
I'm getting random re starts wi fi issues again even after updating to the latest baseband....I'm running stock by the way.... i noticed that after updating some apps from the market this issue of random restarts has occurred again, so i think its gotta do with the updates from market...
[LG Optimus 2x] umutozcano:
conclusion

ok so the conclusion is:

Lg tried to solve this problem, they brought us v10c and d.

to some of us this solved the bsods and to others it didnt.

custom roms the same story, for some it worked and for some it didnt.

other "solutions" the same, for some it worked and for some it didnt.

For the ones that didnt get rid of the bsods or reboots, the only thing left to do is wait for GB and hope that it wil cure your 2x and bannish its demons to another LG phone.

If GB doenst fix the problems i'd send the phone to repair under warranty until they give you a proper device or in case you have VIP service you swap until you get a working device. Or throw it out of the window, change it for a S2, or sell the problem to another guy(not nice):cool:
[LG Optimus 2x] davew:
That sounds like a perfect summary of the situation as I understand it :(

I have sent my phone for an in-warranty repair. If it doesn't work after that then I will throw the bl**dy thing in the sea.
[LG Optimus 2x] omair.shabir:
Not had any problems myself
[LG Optimus 2x] sander-m:
Yesterday I flashed from stock 10d to CM7 build 127 and again the BSOD problem is there, every time I charge the phone.

It's really strange because on 10D stock (2.2.2) I have 0 bsod problems...

I hope CM devs can fix this. I have this issue on all CM7 builds I tried (70+ up to 127).
[LG Optimus 2x] luik:
Did you update the RIL library ?

Download "getril" from market and check/update after every CM ROM update.
[LG Optimus 2x] sander-m:
Yes, I always use Getril app. It does not solve my problem. Im using bb 725 and RIL 725.
[LG Optimus 2x] zebbe77:
Strange I charge my device every night and don´t have the problem. Have also been using CM7 since around #72.
[LG Optimus 2x] sander-m:
When and where did you buy your phone? Maybe you have a new revision. A lot of people have this problem but some have no problems at all. I have also tried a different 3rd party charger but it doesn't help. I think it has something to do with the hardware and the combination of the software driver. On 10D stock I never have black screenof death.
[LG Optimus 2x] zebbe77:
I bought mine here in Sweden about 2 months ago. After reading about all the BSOD´s I also think that the first phones that LG released have some sort of hardware failure.
[LG Optimus 2x] axepted:
You can select to not turn off the screen when charging the phone, it works for BSOD when charging....
[LG Optimus 2x] vonkleist:
Hi guys.

I'm not sure, but I think this has something to do with the suspend process from Android. I did set the display off up to the top number (30 minutes), and even then I've been trying to avoid it to go to sleep (obviously battery discharges very quickly, but I'm just testing). Not a single reboot or shutdown. But if I let it go to SUSPEND state, it gets powered off after a while, no doubt.

Maybe there's some kind of bug on the kernel or the mainboard of this that avoids it to do a successful SUSPEND/RESUME process.

This is what I've seen. Maybe doesn't get to a fix, but could help to look for a solution.
[LG Optimus 2x] Frejdan:
I am also on 127 and I don´t experience bsod as a problem. With that said I have had two cases of bsod, one a couple of months ago (nightly 62 or something) and one a week ago on 127.
[LG Optimus 2x] sander-m:
It's strange that some people have CM7 bsod problems and others (like you) have almost 0 problems with it...

Yesterday I flashed O2X FLAIR FR v2.0 LITE EXTREME (froyo), and again the BSOD problem occurs: every time I charge the phone. This is very annoying because I use my phone as an alarm clock every morning, but the phone is completely dead when I wake up and I need to pull out the battery to get the phone working. The backplate of my phone is not even sitting 'tight' anymore, but loosely now because I needed to take it off really a hundred times to pull out battery. :mad: Now I'm starting to hate LG even more. I really hope LG's GB rom will be good.
[LG Optimus 2x] tomsi91:
It all have easy solution, if you have BSODs, restarts, etc. you have defective device. Stop talking about it for months, go to the shop and use 24 moths warranty. It´s simple and effective. They repair it or give you new device and you will be happy since this time.

Than you will have no restarts, no problems with all ROM, kernel like me.
[LG Optimus 2x] davew:
I came to the same conclusion, but I won't know if it was the right decision until the phone comes back from repair.
[LG Optimus 2x] bodmark:
I totally agree, having had the phone for months now and only found ONE solution to prevent the Black Screens of Death (as we affectionately call them..).

That ONE and ONLY one solution, regardless of which Rom I'm using is simply to PREVENT the phone (CPU) from sleeping. It is exactly a Suspend / Sleeping / Resume issue. Don't know whether it's the CPU chip ( but I suspect this as it's this area that gets Hot when the BSOD happen) at fault or what..

I now use 2 Apps which prevent phone from sleeping. the trouble being that some apps which are supposed to don't do this consistently (only my Maildroid Email app does so faultlessly).

If you prevent CPU from sleeping consistently, I am even able to set a normal timeout and the screen going off Doesn't result in BSOD. Even don't experience any trouble while charging with screen off.

I do however have to endure the battery drain as a result of the CPU remaining on and only achieve 8 - 10 hours in use. Not good, but better for me than removing battery constantly.

I too hope the imminent software update GB will fix this issue... and hopefully it's not a hardware failure.
