If it is there with every rom, then most probably it will be a hardware problem. Could be a problem with the GPU. Unfortunately there's nothing we can do ourselves if this is the case.

I have never faced such a problem.Not with overclocking even.So it could be a hardware problem.Try giving it to the service centre.
P.S. if u still have warranty, then u'd better flash the original firmware to save up few bucks

Yeah I should flash the original firmware!

Was the camera working fine with the stock rom? If not then its a hardware issue. Else I think camera is not working fine with CM.
You can try out Camera360 and check if it works fine.

Then the problem is the combination of rom and kernel you are doing, try the rom with the kernel it brings.

If you're having problems with Cyanoge, I can personally recommend any of ThiaiZ's ROMs. There are some different versions, see which one fits you best.

i like it so far, so much faster than stock rom.
only thing don't like is that home key doesn't function any more. how can i fix this?
Hmm...Did you do all the wipes in the recovery? Like wiping /data, /cache and dalvik cache? Installong another rom doesn't fix?

Camera problem

I recently flashed CM7 on my phone, everything is gonna alright but there is only problem with camera function, it crashes frequently. Is there any camera app instead of default app to solve this problem.

The problem is from the kernel try flashing other kernels or you choose not to over clock alot that is NOT more than 600mhz that ll solve your problem.

As stated in original thread if you hear sound but black screen you need to send him logcat and device model. Its a known issue.

Same here.I was able to run once, and thats it.We shoud send log cat or something to devs...

I didn't try it yet but...
Could work if we'll trick the program to think that it's on another device? I mean changing the identity of O3D, as it happens in the Xperia 3D rom by Meemo if I'm not in error. With that ROM the update program and Google Play were seeing my phone as a SE Xperia not as LG O3D!
I'll be peeing against the wind but it worth a shot to try.
So we have to edit build.prop?We need to find the line where device name is i gues...
Will try this...

Looking at my build.prop I see the lines:
ro.product.model=LG-P920
ro.product.brand=lge
ro.product.manufacturer=LGE
Anyway you should see first a build.prop file of a device that you know it works
And pay attention to what you modify because you can brick it, get a boot loop or something like that.
And you should ask advice from a developer... they are all good guys and I think that would help you gladly.
Again I might be peeing against the wind - but you never know.
I did a full backup and then edit build.prop to NEXUS S.With no luck, i got the same error.Will try with different edit in build.prop... Thx for you help.:thumbup:

Thanks.But one stupid question: what version have you tried? I guess the Neon version because ours doesn't have Tegra.But one I've tried Tegra designed games and some of them worked.See my early threads.I'll try also but I'm not so brave with coding or something like that
Sent from my LG-P920 using xda app-developers app
Both versions.None of them working.But one thing that I've noticed is that if you go to kill application and clear cache you'll see that this one, the cache is about 45 Mb which is a lot and therefore freezes the phone.Could this be a problem?Cache file too big?I think that in the end it needs bigger RAM, like 1 Gb.

Weird stucks on 4.1.2

Ever since I uploaded from 4.0.3 ICS my phone has been getting "stuck"... The screen gets crazy if I touch it, the other buttons won't respond. The only way I seem to fix it for like 2 minutes is by locking it and unlocking it... When I bough it, it came with 4.0.3... Since then I moved from ROM to ROM...
4.0.3=>4.1.2
4.1.2=>4.2 Cyanogenmod
4.2=>4.1.2
4.1.2=>4.0.4
4.0.4=>4.3.1 BeanStalk
4.3.1 BeanStalk=>4.3 PAC
4.3 PAC=>4.3.1 BeanStalk
4.3.1 BeanStalk=>4.1.2
I left cyanogenmod because I didn't liked the look of my phone and because I wasn't able to play some of my favorite games.
I left BeanStalk because the camera.app kept crashing and forcing reboot.
I left PAC because the keyboard wouldn't show up and I wasn't able to finish the set up.
I left 4.0.4 because some apps were too new for it.
On 4.1.2 I get a lot of times stuck, but in other ROMs (even on Stock 4.0.4) the frequency of stucks were less...
I'm sorry for my awful english. I am from Argentina.
I'm really freaking out because each day my cellphone gets stuck even more!
Flash back to stock and if you still have problems it's probably a hardware problem. http://forum.xda-developers.com/showthread.php?p=26056924

I am on stock. I placed 4.1.2 without any name because I was trying to say "stock. Not a custom". But if it worked before perfect on 4.0.3. How is that possible? I mean my phone fell a couple of times but from by bed... I don't think it would harm it a lot since I have a carpet...

Oh sorry I didn't understood before. Maybe it's screwed but the thing is that in BeanStalk it didn't got stuck but I wasn't able to use the camera. Also it didn't got stuck in PAC but the keyboard wouldn't show up and display error messages all the time. I might go back to 4.0.4 since it works better than 4.1.2 (in my case).

Move all your files(pics,movies,music etc) to your computer. Format everything and try Odin again. Make it like the phone was new right out of the box never used. Troubleshoot from there.
