You seem to fail on flashing CM7 I guess. What you need to do is just downgrade to 2.2.2 stock rom. Search in "General or Development" to find guidance

Sounds like you flashed another devices CM.​ IF the your O3D start on its own remove the battery Hold Volume Down + 3D Key insert the battery let it boot to CWM and Flash another rom​

[Q] Need help with an Optimus 3D

Hey guys i just bought an Optimus 3D from a friend . He changed stock ROM with an JellyBam 3.2.0. My question is : How can i get it back and use 3D mode , or what ROM is easy to install which supports 3D an all his stuff . My baseband is V21a (don't know very much about this) . If there are anyone who can tell me exactly what steps and which custom ROM i need to use please help me. I got stuck in so much threads didnt understood too much. Thanks

AW: [Q] Need help with an Optimus 3D
First of all, you need to know wich rom you want, because if you want to go back to gb you have to do other steps then if you want to go on ics... if you want 3d and everything try to flash ics, maybe darkroom ones or xbsas rom.

i've read xbsas's guide but i'm not sure what i need to do. I need to inverse 2 pins on usb cable or something like that , i dont know how to change baseband and stuff , seems preety hard, atm i have jellybam 3.2.0 , was the only one where camera works . In other roms camera was freezing. Anyway if there is an easier way to install that ICS let me know . Thanks again

AW: [Q] Need help with an Optimus 3D
Yes, its very easy, you dont have tpo cross any cable, you have to flash two files via smartflash. Camera is working on ported ics, im using darkrooms rom and so far i dont have problems.
I will search the right thred you need and post it here.
Edit: this is the first step you have to do, the files you need to flash bin and fls is in xbsas thred for first ported rom
This one is for smartflash:

This is very usefull , thanks man ,, i have 1 more question. Do i need to change baseband first then to flash ROM via smartflash?
And what about darkrooms rom , he has any bugs or stuff? if you have no problems with it i should consider flashing that one

AW: [Q] Need help with an Optimus 3D
Yes you can flash darkroom ones i have no issus so far, everything works great and i use it 2 weeks now. You can flash darkrooms one bit first you need to flash the first ported rom. Then root it and then you can flash darkrooms. At least flash baseband. You can flash basebsnd after you flash ported it doesnt matter
For more questions you can ask me

So i dont need to change baseband first or something like this . Just like i said mine is V21a. So it should work right w/o problems right? And other thing: i use win7 . I might have problems with drivers ?

AW: [Q] Need help with an Optimus 3D
No, with drivers no problem and whnen you flash the new ported rom, your baseband will be overflashed with another baseband, because when you flash ported rom you flash two files bin and fls, try this baseband when everything works is goid if not change baseband its the same thing like flashing the bin and the fls file but this time you add only fls file you will understand this betterwhen you tried to flash ported rom first time

Omap is the right one, if you had installed omap, then everything is right. In the next step you have to change comport from omapdriver.

so i dont need to get other drivers. in ports i cannot find that lge thing where i 'm suposed to change port to 41 like in pic

AW: [Q] Need help with an Optimus 3D
Ok pay attention, when you installed the driver, put out battery from your smartphone, and everything else. Afzer that, connect usbcable with your pc ( not with your o3d) only woth pc. Then connect it with your o3d and hold vol up button in the time you connect your smartphone. DONT RELESE THE VOL UP BUTTON IN THIS PROCESS. Your pc do a sound that the phone is connected, then it does the sound that it is disconnected, when your pc made the 3rd sound that you smartphone is connected put fast the battery in your phone, DONT RELESE THE VOL UP. wait until you get sw mode on screen. After that you can configure the port 41 in device manager. I made a pic for you..

Could do with some help after doing restore via LG mobile support tool.
UK p920 that was bought second hand and unlocked to all networks I am using a T-mobile[ UK] sim card
I updated from froyo to 2.3.5 gingerbread 2 weeks ago using LG mobile support tool. The sim card was in at the time.
update successful and then rooted phone all ok. Tried doing backup of current rom with rom manager and failed. also tried orange, and rom manager,none would backup anything. tried flashing rom and bricked phone!could not even get into a boot recovery. Last resort I used LG mobile support tool to download and auto re-install 2.3.5 (without sim card in) didnt think this would affect anything. Phone booted up and all is ok, did a titanium restore of apps and settings all ok, but cannot get the phone to connect to sim network-tmobile.
Current config; model number LG-P920
android version 2.3.5
baseboard version L6260_modem_sic_01.1042.00
kernel version 2.635.7+
build number GRJ90
software version LGP920-V21e-APR 19 2012
Has the recovery loaded the correct version for my phone?
I am a noob so please reply using basic language and instructions, thanks for reading.

AW: No sim network
Have you changed baseband ? Normally it is a baseband problem.
The rom must suit with the right baseband.
And watch if you have imei.
EDIT: are you on stock 2.3.5?

[Q] Best rom for O3D?

Hello. I would Like to know which is the best ROM for O3D. with good battery life , working camera,3D support and less bugs it have its better. I tried NovAndroid It was really fast but The battery discharged in 2-4 hours. Then I tried the CM 7 but it was even worse then NovAndroid and then CM 10 nightly which had too much bugs. Right now Im using JB 4.1.0 but camera doesnt work and what is worst is that if your phone lags just a little bit it freezes and after some seconds the LG logo appear forever until you take the battery out

well said sir.

Cm10 was that bad cause you didn't install wkpark's bootloader v1.25. If you want 3d you have to use ICS e.g. Xbsall's v8.

If i install the bootloader will it work better? The worst problem was that when phone freezed even when trying to play youtube video and I needed to take out battery 4 times a day because of freezes. And If I install all the things which are needed with ROM which would be better xbsall's rom or cm10 / or ThiaiZO3D? I will not act like I know these things I am total noob at this . And Can I brick my phone by changing bootloader or baseband?

Don't do Cyanogen mod it will brick your phone.
ICS is good but you can't root it. no recovery mode.

I have installed Cyanogenmod on Multiple Devices not once has it ever bricked a device infact you're more likely to brick your device flashing official updates xbsall has a a guide to recover from a brick so its not even an issue. please do some more reading ics has root . it has recovery just not a Custom one (CWM/TWRP)thats why wkparks Bootloader exists.
IF you Ain't Devi'N Don't a Start A thread in Dev Section.
@Mod Close thread or move it to General.

actually the root doesn't work because you can't get into recovery.

Is there any guide to set up dualboot? and can I brick my phone with it and does It make phone slow ? I heard about xbsalls rom but it is saying that I first need to install different kernel but I dont know how to do that because my recovery doesnt have that option. And Which 4.1 or 4.2 would you recommend? I already used jb. but camera doesnt work and It would be really pain if I want to take a quick picture and I would need to reboot my phone for different rom with working camera. And If I install kernel will it be set on both of the roms? or I can set different for both of them?. btw Thanks for reply

I alreaady tried CM both 7.2 and 10 both didnt bricked my phone and I had CWM recovery working with them...and root too...

CyanogenMod works fine - 100%. The reason it get bricked is BECAUSE whoever installed it didn't even pay attention.
And regarding the CWMR in CM10 - it works. I used ADB-flashable version of OMAP4 BIOS (wkpark V1.25a bootloader), and flashed CWMR at the same time as an option.
P.S. I used SuperSU as original Superuser wasn't properly installed in the nightly distro of CM10. Nevertheless, root works fine.
P.S.S. The reason I bricked my LG Thrill 4G was because I was trying too hard.

You can use a recovery tool from sony to return your phone to stock. You can find the tool from sony official website, just download and install the necessary usb drivers and with original cable and internet connection you can return the phone to the latest stock rom available for the phone.
