Hello!

Happy new year to everybody...

You should really upgrade to latest CM7.2-RC0-KANG – they are a lot more stable than CM7.1, which is rather old now.

If you still get bsod you should consider a new battery – but first try the latest KANG.

LG 2x off automatic - my suspicion

LG P990 Optimus 2x since he arrived is experiencing this bug, if it goes into standby mode it turns itself off, even if you are carrying. rebinds and not more, i have to remove the battery to be able to reconnect it. it has Android Froyo 2.2.2 baseband and it is 1035.21_20110725 and kernel version is 2.6.32.9 version of the LG-LGp990h v10f. already decided not reseted. the worst is not installed or updated anything to have corrupted something.

I am suspicious of two things: 1 - overheating (because it loads it warms, and use it for a while it heats, then goes into standby mode = off. i have to remove the battery.

2 - loss of signal from the phone company for a long time.

to date already had dozens of layoffs in just 4 days. too hot where I live (Northeast Brazil + - 40c) so I suspect heating.
[LG Optimus 2x] ron_gangte:
I'd suggest flashing CM7. It solved the BSOD issue for me. :-)
[LG Optimus 2x] ceriberto:
thanks for your help, tell me more about this CM7, how do you flash on my lg 2x has a tutorial available? I lay on the subject, because I never installed anything in android.
[LG Optimus 2x] ceriberto:
ron_gangte thanks. more questions. sorry

which version of your CM7? CM7 you just installed or installed something else too?: D: D: D: D: D: D: D: D: D
[LG Optimus 2x] ron_gangte:
I flashed CM7.2-RC0.

You'll find it from www.mediafire.com/temasek

Look in the P990 CM7 KANG folder.

The latest is the KANG 24.

Flash it.

You do not have to flash anything else. Flashing a Custom Kernel is optional. If you plan to flash one.. try SwiftKernel or IronKernel.

If you are new to flashing. Check out the roll-up thread or a thread regarding "How to Flash".

PS : Don't hesitate to click on the "Thanks" button if my post helped you in any way. :-)
[LG Optimus 2x] ceriberto:
thank you so much. ron_gangte

actually solved the shutdown problem in yours? for I have tried several things and nothing has worked. it really solve the problem of automatic shutdown with the installation of CM7 be very grateful for you helping me. because this unit acquired abroad, and I can not return to the seller or even to send a care in my country (Brazil), for only accept equipment purchased for the concert here. thank you so much.
[LG Optimus 2x] ron_gangte:
You are very welcome. :-)

I cannot guarantee that flashing CM7 is going to solve the issue for you. But it did solve the issue for me. So, I'd say it is worth a try.
[LG Optimus 2x] RadioCharlie:
I too had a few odd/random reboots in the space of 3 hours when I got my 2X on Friday. At first I put it down to the clear protective cover on the Power switch but it kept happening. In my case, putting CM7 on certainly helped although I had other issues (painfully slow media/thumbnail cache) on both the Stable and Nightly.

I'm now running BlazingDragon (plus ADW Launcher) and very happy with it. No reboots and nothing major except the GPS which seems to be a known bug.
[LG Optimus 2x] sodade21:
i did upgraded to the 7.11162011 nightly

i tried different kernel 2.6.32.45 - vorkernel

i upgraded baseband to 1035.21_20110725 (i had the 405)

I did everything by the "book" full wipes etc etc.

Even my fm radio is working properly with bluetooth with an apk i have found around these forums...

my signal is good,the wifi is very good,gps i guess is ok 3g ok as well...

i even charged the phone more than 12 hours in complete shutdown without any problems i must add...

everything seemed ok but when i locked the phone...if the lock was more than 15 mins str8 then i couldnt wake it up until i unplug the battery...so any other suggestions..? i have downloaed softlocker to see if this can fix my problem allthough i will not be happy as this is not a solid solution and my phone might be hardware broken somehow... ill give a final shot of install CM 7.2 Kang as a last chance..otherwise ill try to stock the phone again and return it to the shop.... :(

---------- Post added at 04:34 AM ---------- Previous post was at 03:35 AM ----------

I tried to flash the zip via recovery but then my phone did not want to Boot... so i did flashed the 7.111 again..i dunno what did wrong...kang need some things done before? maybe its because i have changed baseband (725) ? maybe i had the vorkkernel? i dunno... :/
[LG Optimus 2x] ron_gangte:
After flashing the KANG, try wiping /cache partition and /dalvik from Advanced in CWM.

The first boot takes 5-10 minutes, so be patient.

If you wanna flash a Custom Kernel, I'd suggest flashing SwiftKernel or Vadonka's Mod of the IronKernel.
[LG Optimus 2x] ron_gangte:
Try flashing one of the newest KANGs. You will not be disappointed. :-)
[LG Optimus 2x] Mungulz:
I was on kangs and was disappointed with widget responsiveness and network drops. Though the latter could very well have been a baseband issue. Bsods were also morw frequent on cm7 than stock based roms.
[LG Optimus 2x] ron_gangte:
Ummm.. weird. I never had BSODs after flashing CM7.

The call quality and widget responsiveness seem fine to me.

Anyways... glad that Stock works for you. The Stock ROM gave me BSODs every now and then. Had to flash HP Kernel to get rid of the BSOD issue on Stock.
[LG Optimus 2x] RadioCharlie:
Thanks, I will take a look and see what they have to offer. I've been nosing around the Developer's forum but need to up my post count so I can contribute. My username is the same over at Modaco (a few posts in the ZTE Skate+2X sub-forums) as well as Crackberry (back in my fruit-based days!)...
[LG Optimus 2x] ceriberto:
Probable cause of the shutdown 2x lg

Good morning. well even before upgrading to the CM7 I tried to find out. by trial and error, the cause of the shutdown. first I thought it was some internal software problem that turns off the unit to prevent damage when spend too much time on energy. then I thought it was a game that was installed (fast hd 5). and come to think it was the memory card. some comments aki report calls long after shutdown. and watching an episode of "Monk" kkkkkkkkkkkk tried to see what was in common between these facts. I understand that is the HEAT. because in all these actions the unit heats up very, call, carry, play. and besides, I put my phone in a protective layer of silicon (TPU) which caused further warming. I tried to stop him carrying on a desk notebook cooler with and without the silicone case, he charged the battery and not hung. used it all day and rebooted and he hung up. so I'm warming has concluded that the problem is (together with a bad rom, which really hinders the performance of the device).

but I'll upgrade to the CM7 as counsel of our friend "ron_gangte."

---------- Post added at 02:43 PM ---------- Previous post was at 02:25 PM ----------

My advice, which until now it's working: Do not load the device with a silicone case (I did a huge square hole on the back of my silicone case to not warm). Click on firm surfaces, with the display down, no bed, sofa, fabric or things that hinder dicipação heat.

So far these measures have worked for my case, maybe try to work for you too.
[LG Optimus 2x] ceriberto:
further proof that it is heating, I played angry birds until the device esuqentar, oh let him go into standby mode, and then came the crash with automatic shutdown. I am checking the question of whether rom problem, because if it was just warming up, so he shut down if the temperature hit the shutdown happens. then it is a set of heating with a bad rom. screening test for the CM7. eespero succeed permanently.
[LG Optimus 2x] bodmark:
Some further Help

As I have posted previously, the only consistently reliable resolution to curing the BSOD's and Shutdowns on Stock Lg Froyo 2.2 (which seems to come pre-installed on the majority of Phones circulating) was not by using custom Roms, but the problem is only managed with Applications downloaded from Market. These Apps prevent phone from sleeping, which is excatly the fault, the inability to wake up successfully from sleep.so if you are using LG stock 2.2 Froyo then Install " Softlocker " (or any app which prevents phone from sleeping in standby-there are a few). The consequences are little more battery drain though. but it works. even better if you have 2 of these Apps running as sometimes apps are shutdown by Android due to memory constraints, but they should restart almost immediately before any problems occur.

The other new method involves upgrading the phone software to the new Gingerbread 2.3.4 LG update which Lg have FINALLY released (but you need to update via LG PC update tool. This has been a good solution so far - No BSOD's, though I did experience one shutdown while charging, not entirely sure why. but generally, LG seems to have cured the majority of the serious issuses (maybe after i informed them of why the BSODs happened, with the phone sleeping fault).

---------- Post added at 08:53 AM ---------- Previous post was at 08:46 AM ----------

Once you install the new Gingerbread Update, LG hasn't made it so easy to root using the straightforward methods ( superoneclick, etc) so you need to follow the instructions on the following link to Root, then you're all ready to go.

http://www.lg-phones.org/how-to-root-lg-optimus-2x-android-2-3-4-gingerbread.html

Ps. I spent Much time persuading LG UK of the problems and the discoveries i made with the phones UNUSUAL sleeping habits.. and finally i believed they've taken heed of my advice. The new gingerbread is stable, with occasional Radio reconnection issues..but its thousand times better than Froyo version.

So go on follow the procedures above and you'll be good ( and keep your sanity )
[LG Optimus 2x] ceriberto:
thanks! bodmark

I'll try it your tip. but since I contacted the seller who bought this product, we are in the process of return of 2x lg. For even finding an alternative solution, it is still defective. then you better switch to another while under warranty. again want to thank all who participate in the xda forum, I have found many guys here who help other members. thanks = O.B.R.I.G.A.D.O in Brazil.
[LG Optimus 2x] sodade21:
So finaly after i have tried many many different roms and kernels, i must say that my phone seems to like only the stock rom/mods rather the CM7 and or Kaes...

i wanted to make a flash in stock but it was not froyo but gingerbread.. and it worked perfectly! after 2 days of no shutdowns or stuck in sleep (wich was the most frequent problem) i decided to try some other roms based on stock.. and with all i was pretty stable and had not the sleep of death problem anymore...so then i decided to try again the latest kaes and here we are again.. rarely now i got sleep of death so i decided to use the softlocker..but my battery drainage on that "light sleep" is very harsh...

i could use some stock rom but i have seen some little things on CM7 that i want to the stock rom as well such as the rename of folders onscreen (where the widgets are) and be able to add the thumbs on those folders... is that something tha ADW launcher does or its something about cm7 kaes? cause sadly i cant stay on kaes cause its not stable for me... its faster than everything though with the ironkrnl but i will chose stability over some speed.. :)

What can I do? My Phones also shuts off.. is the solution to avoid warming of the battery?

[LG Optimus 2x] Byteater:
I have already had this problem and I solved only with a complete phone exchange while the battery replacement didn't work.. i think the problem is only motherboard related.. All the lg firmwares now are stable and have been already patched.

[LG Optimus 2x] Medizinmann:
Hello!

Are you really on the latest KANG?

...and using the latest ironknL?

The most recent versions are perfectly stable for me.

And when I am using OC up to 1.3Ghz I even don't get overheating while the phone is under heavy usage - it will get warm but it doesn't crash...

...while I can provoke a crash using 1.5Ghz after playing games for an hour or so and then launching AnTuTu the phone will/might crash from overheating.

But this is clearly beyond specs..

A little warming while charging or while doing its tasks is normal.

First of all do you use the latest Firmware?

The older LG Firmware gave me SOD/BSOD.

Yeah, there is of course also always the chance of faulty hardware.

But most of the time it seems to be related to the older/faulty LG stock rom.
[LG Optimus 2x] yaggy85:
stock rom has stopped my phone from BSOD'ing. CM7 and various other roms all had the problem.

im running stock GB 2.3.4. - v20d
[LG Optimus 2x] anhletuan:
Take a try on this.

This issue occured to my new LG Optimus Black which I bought last Friday, I have searched over the internet and tried few solutions and I found that the reason is in the SD card, I concentrated to the SD card and improve battery capability, and now my Phone is normal.

So users who found this problem on your phone, please try one or both of the followings:

+ Main points: Using your computer to format the SD card (remember to back up your files first), but you must format it not using quick format in the format options in Windows, which might last longer but solved the problem. Moreover, other settings should be left as "system default".

+ To improve battery life and avoid unwanted problems to your phone, please use the official battery charger which comes with the phone, because it could extend your battery life and prevent overhead to the phone as well as the battery.

After formating your SD card, if it still automatically shutdown, try putting out the SD card for a time and see if the problem still occurs or not, if it does not happen again, try think of replacing your SD card with a new one.

I have tested this out now successfully to my LG Optimus Black and it does not happen again for recent 3 days and want all of you to finalize your issue with a brighter scene. Sorry if my English is not correct, I come from Vietnam. :)

Hi to all,

I know that i open a old topic, but i also have problem with restarting my optimus 2x during charging or playing angry birds, but most of the time during charging. I am using cm7kang-O2x-135.2 ROM.

I notice also that sometimes it overheat during charging, and sometimes not. If i put some new ROM (IC), can it be solved?

Thank you
[LG Optimus 2x] pekkidboy:
I assume you're using temaseks kangs... Just do a fresh cm7 installation with all wipes and you'd be fine.
[LG Optimus 2x] luka78:
Yes, I am using cm7kang-O2x-135.2 ROM, and that is temaseks kangs. And what ROM should I use, the same one 135.2 or some other?

Thank you

Why the need for excess questionmarks?

Either way try disabling wifi or data while charging overnight, only tried bsods while they were active
[LG Optimus 2x] AnishTS:
Hi All,

May be a dumb question.

Whether the BSOD's are hardware issue or software issue.

Whether BSOD & Device becoming slow issue exists in CM7, ie whether this issues can be resolved ?

Anish
[LG Optimus 2x] Rayman96:
I don't understand you but bsod is often dependent on phone. Some are more likely to get it. I don't have any for example

I have different problem. When my battery is full everything is ok ( it is possible to play games, surf on via net ) however when it is around 30%-40% when i start a game or 3g a few minutes later screen shows me a massage that my battery is empty and my mobile will be turn off. When i turn on it again battery status has a " X " inside ( so battery is empty ). Its not possible to drain 30% battery in 2 minutes . It is only when I play games or use 3g , when phone is charged more ! Pls help me

PS now i am on the stock rom

I had CM 7.2 CM 10 and ICS. Before ICS everything was ok ...

I tried:

battery stats wipe

full drain then full charge

No effects
[LG Optimus 2x] rmzalbar:
This sounds like a hardware problem involving your battery.

1. Is your battery old? Consider replacing it. Battery tracking schemes start to have trouble estimating battery status once the battery degrades to the point where it doesn't respond as expected. One thing that gets worse when a battery ages is current delivery. The voltage will be high when not under any load, but fire up a game and the increased power draw causes a voltage sag when the battery can't keep up with the demand.

2. Clean the contacts on the battery and in the phone. A bad contact would also have problems carrying current, though voltage can still look good when not under load. Use contact cleaner, or a gentle scrub with a pencil eraser to remove oxidation followed by alcohol to remove any oil left behind.

Random Reboots

I had occasional BSODs und reboots in FroYo but things were alright in GB.

Since I got ICS (civato Stock Kernel Rev 2.0) it happens really often that I got these reboots: today I had like 5 reboots within 2 and a half hours. The strange thing is those reboots seem to be really random and not reproduceable.

Sometimes my phone works rather stable, sometimes not.

Is there anyone else with this issue?

Cheers!

Flickering, locking Screen and BSODs :(

I started facing this issue 2 weeks back. The phone would lock on its own specially while trying to play subway surfer, using WeChat, changing camera settings. I repartitioned my phone to support new BL and installed tonyp's cm10.1. It definitely is not the ROM as i have tried numerous roms including Stock GB and ICS. Neither is the BL as I have swung multiple times between the partitions system to support new and old BL. However , I noticed that the screen would not flicker or get locked while the system is in recovery. I'm using TWRP. So I would summarize

1. Issue is not the ROM

2. partition system for ICS or GB BL has no effect

3. I have tried multiple SD Cards and tried without SC card and the issue persists. That rules out SD Card too.

Though, I havent tried the battery though. I'm reluctant as I changed the battery just a month ago.

Any help or suggestion would greatly be appreciated.:good:

Phone shuts down

Hi everybody,having a big problem with this phone,everytime it sleeps i have to remove the battery to restart,so not usable really! no matter what roms i've used same problem sometimes constant reboots too! I'm now trying tonyP rom cm10.2 and i've enabled auto hot plug anything else i could try??

I can actually confirm that when my problems started was after inserting external 16GB sd card (used on HTC Desire w/o problems)....

[LG Optimus 2x] Elf89:
I think we have to make a distinction beetween random reboot and freeze issues. Topic was originally created for freezes issues that are IMHO much more annoying than random reboots :mad: .Anyway it's obvious that a reboot is not normal and must be fixed like any other problem!

Referring to the shut off problem... Many of you are experiencing it during charging so when the phone is less used...If i red carefully no one had locked screen and after 1 second tried to use the phone without success! So maybe the problem is caused by processes that after some time crash and freeze the phone. By the way this phone had been introduced in shops of all world at least 20 days ago... If problem was caused by crashing processes (and every 2x in different countries has approximately the same software) a lot of people would have experienced it! My 2x has 1 day and i charged it during night when it was off so i don't know if mine is affected by issue (scared).

I think that everyone should email Lg support to inform about this and ask for device change. They can't keep ears closed!!
[LG Optimus 2x] Elf89:
Mmmmm

I red that a 2x user wasn't able to lock any satellite, he removed SD, GPS FIX in a little time! SD card maybe introduce some problems... let's see how it will develop...

it seems like cpufreq-dvfsd totally hogs the telephone and eventually brings it down until it dies, i believe that you shouldnt really think about the 50% cpu-drain as only 50% but might be a total 100 since its a dualcore device.
