Boot back in to your recovery and wipe cache and dalvik cache. Format system and then install your ROM. There are major differences between CM11 and CM7. When making big jumps like that it's always best to format system before installing a ROM.

I just did factory reset via cwm
And still have a problem
So do just what you say and do
system format?
You mean that you are going to have a system folder in the mount and stroage given formatting?

In CWM select Wipe data/factory reset. This will wipe the cache, dalvik cache and a couple other partitions. Then go to Mounts and Storage and select Format System. That will format the system partition.
Now go back to CWM home screen and install your ROM.

Hi,
May I ask for help here (instead of creating a new thread) ? I have the same problem: The device is booting loop at the LG screen. Bricked it when I wanted to save the ROM with ROM Manager.
I have no access to recovery mode, but Emergency mode does work (With and without battery).
I've followed multiple guides, including this one:
Most of you are stuck on a yellow screen with”Emergency mode!!” or the phone is not responding at all. You guys wanted a custom rom like Optimus Prime-v2 and let me tell you, this time it will work. Optimus One P500 comes with stock android 2.2 – V10a, V10b … and android 2.2.1 – V10n. They might be done for different regions depending upon the phone release and its popularity and definitely bug fixes and enhancements. To have Prime-v2 on your handset you will require V10a or V10b on your handset. Reason, V10n stock cannot be rooted easily. Rooting the handset is must if Prime-v2 is required on the device. Steps to install V10a, V10b series. I am using Windows 7 32-bit, 3 GB RAM laptop:
1. Clean your system first; get rid of LG PC suite and other stuff shown in Uninstall Program with vendor name as LG. Remove MSXML builts from the handset. Remove Nokia and other drivers if they are on system like Ovi suite etc. I also removed a lot of Microsoft runtime environments. Not sure about the reason but it worked for me.
2. LG usb device drivers, download the application B2CAppSetup.exe http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe .
3. In the Menu Bar, click "Options & Help", and click "Country & Language". Select the appropriate Country & Language. I used India and select P500 from the list that popup after you change the country and region. It will download, install and save the drivers somewhere in C:\LGP500\USB_Driver, it will prompt to open the rar files, just click and install the exes seen in them.
4. Reboot the system.
5. Right click on Computer -> Properties -> Device Manager and see for three drivers – LG android usb modem, LGE serial usb port and LG composite USB device. Disable the modem driver and reboot once again.
6. Switch off the phone and press volume up + BACK button + POWER button. Phone should turn yellow with text “Emergency Mode!!” To switch it off you have to remove the battery (I know it hurts, but that’s the only way out here). Switch off and let’s continue with the setup.
7. To do the KDZ of system you will require the KDZ software updater, links keep going off and on internet. Try searching for “KDZ_FW_UPD_EN” or “KDZ_FW_UPD_EN.7z” in Google and download the software. It should be somewhere around 2.3 MB. To use it you will required some good version of WinZip or winrar again Google it and install the 7z archive utility.
8. Install msxml.msi as the manual or readme.txt says to do so.
9. To get the V10x Official ROM, you need to first determine the ROM of your choice. List of all firmware available for LG Optimus One P500 (list of codes) http://csmg.lgmobile.com:9002/csmg/b2c/client/ezlooks_model_list.jsp?model=LGP500 , search for your country (use IE it looks sexy in it), I looked out for IND/INDIA. Download link to the ROM is http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500/XXXXX/V10a_00/V10A_00.kdz where XXXX is code from list of codes. In my case it was: AINDBK. Save the file.
10. Prepare the handset by removing the SD card and boot it to emergency mode (some are already stuck on it so reading this post…: D) using the key combination stated above.
11. Connect to the PC and it should say, installing drivers’ blah… blah … your device is ready to use now.
12. Run the KDZ updater downloaded in step 7. Select 3GQCT in Type, DIAG in PhoneMode, and browse for ROM V10a in KDZ file and hit Launch Software update. Wait for somewhere around 5-10 minutes. It should say ===FINISHED=== in the log window of updater.
13. Handset will reboot, if not wait for another 5 minutes. Unplug from USB and try to switch it on.

My problem is that KDZ still doesn't find my phone after all these attempts - I uninstalled the device driver, then reinstalled it succesfully (B2CAppSetup.exe). I reboot, install msxml.msi, and start KDZ.
Next, I power my phone in Emergency phone, plug it, and it is detected for the first time by the computer. I do have LGE Android Platform Composite USB Device, listed in the Device Manager, as well as LGE Android Platform USB Modem.
Using KDZ, I select the "3GQCT" type, phone mode "DIAG", with the correct KDZ file I've downloaded earlier. Once I launch the software update, phone is not found.
I've tried several times, including desactivating the LG Modem from the Device Manager; unfortunately, when I disable it I need to reboot - I do reboot, but then the LGE Android Platform Composite USB Device is absent from the device manager, and isn't detected by Windows at all, until I fully reinstall the driver (...).
I really don't know what I'm doing wrong - note that I use a laptop with Windows 7 x64; I know laptops handle USB port in a different way than desktops.
Can you help please?
I must be SO close... =(
Thanks, I really appreciate it!

First, serious word of advice. Stay away from ROM Manager. It does not handle this device correctly.
It sounds to me like you are not entering Emergency Mode correctly. Yes, the LG USB Modem must be disabled. Power off the device. Press the "Back + Volume Up + Power" buttons together until the device boots to Emergency Mode. Now connect device to you PC/laptop. This can also be done with the battery removed and the device off. Same method except no power button involved. Press the "Volume Up + Back" buttons while attaching your device to your data cable, assuming it's already attached to your PC/laptop.
The attachment I've posted is a stripped down version of the KDZ Updater. All you need to supply is the correct KDZ file for your phone. This one does not require any of LG's other crap software either.
Download to your PC. Extract to a folder of your choosing. Read the ReadMe.txt carefully and follow it's directions to the letter. I just used this to revive two ( 2 ) bricked P506's.
If you can boot to fastboot mode, there is a tool in my signature, Android Flash Recovery, that is designed to flash a recovery to a device with fastboot. So you have two options to restore, revive your device.

Hey, cheers !!
That was all I needed to do with this simple version, the update got applied properly, and I saw the FINISHED message.
My phone "rebooted". Well, what I see now if the Android logo with a big " ! ", which is normal according to what I've read.
I will do more ressearch to make sure what I do if correct now: is this safe to power off/reboot at this screen? I believe it's the last step.

Holding the power button does not shut it down - pull the battery, right (It won't screw the thing right before the end ? XD ) ?
Look.. correct:
12 - Start the phone again. If you get stuck in a screen with an Android and an exclamation mark ("!") in a triangle, just unplug the USB cable and the battery. Plug the battery again and start the phone. It will take 2 to 5 minutes to reboot for the first time and the boot animation will be the stock LG (your carrier's stock animation is lost for good), but chances are your phone is intact, with all it's apps and configurations working the same as before the incident. When the boot finishes, turn off the phone again and put back the SD Card you took off on the first step.

If KDZ Updater says it's done and your device has rebooted to recovery, then yes you can pull the battery to shut it down. You may still need to do the key presses for a factory reset, but the key combo has slipped my mind for the moment. Old age...

Really nice, I have the Android logo !!
I will wait - people says it can take up to 5-15 minutes or even more - I won't shutdown on the logo.
Letting you know as soon as it's done.
***
After a while, the device booted, and I had a few messages saying it was restoring all the settings!
No data loss! Nothing (I had backed up my contacts and apps on my SD Card already - I was unsure if I would have loose my SMSs, I didn't) is lost !
Dude, seriously, thanks A BUNCH - this is ridiculous, I screwed the phone up at like 10PM yesterday, and did not went to sleep until 2AM because I couldn't fix the thing (I had access to FastBoot at first. I did a process to restore it from Fastboot, it should have worked properly, but then I only had access to the LG logo. Man, I thought I was toasted, and had to spend 50$ for a new phone, just because of a stupid mistake. Never would I thought that SAVING the ROM of my SD card would have screwed up the ROM!)...
I spent like 6 hours today trying to fix it, reinstalling the drivers over and over again... Installing a fresh new Windows XP on a machine, just so I could install everything on a new operating system to figure out the problem...
That was just plain crazy, seriously.
****BONUS****
The first thing I've noticed when I booted my phone was the BLACK notification bar
I really love black, and I once did ressearch a while ago to see if I could turn my white bar into black (I have Android 2.2.1), but no success.
I just realised I got it updated "accidentally" to Android 2.3, and so I was on Android 2.2. since 2011 (when I bought it) !
Well, nice addition, it is sexier with black
I belive it's because of the KDZ file I've used... I had a really hard time to find one, all the links were broken, from 2010, it's a old phone. I found the KDZ from Koodo, Canadian French, exactly my own.
Guess I "accidentally" upgraded to Android 2.3 then Nice addition !
I have no experience at all with fixing Android devices / ROM stuff - I'm used with Windows/Linux and others, but Android (although Android is a version of Linux) is another thing for me.
THANKS - seriously, I wouldn't have made it without your help.
YAY

[Q] Unable to factory reset

Yesterday my phone started acting up. All running process crashed and not many was able to start. I had to constantly click "force close". I think this started after I installed the Google+ app, but not sure.
I have tried uninstalling all unnecessary apps, without luck. I then tried wiping to factory settings by using the Android menu, but without any changing. I then tried by holding vol+ and power, going in to recovery and wiping both to factory and app cache. This doesn't change anything either. By googling I can see some suggests to hold vol- and power, to get to a another wiping-functionality but this just boots my Nexus S to normal state - no menu appears.
Has anybody an idea of what I can do?
Edit: more info; if I click "Report" and investigate the message sent to Google, I see that error has something to do with SQLite-relatet classes. Which makes some sense, alot of my changes are reset each time the phone is rebooted. For instance did I miss a call a couple of hours before the phone went crazy - this is shown at each boot in the notification area eventhough I clear the area and/or goes to missed call section
Factory reset via menu does delete all your "custom" apps, so I'd say it's not one of the existing apps causing problems.
The way you describe function after your factory reset sounds like factory reset didn't work properly.
If you feel safe I'd recommend rather flashing 2.3.4 again using either Odin or the OTA zip from Google (requires open bootloader).
I think you're right that factory reset doesn't do what is expected. Once I click it, the phone reboots and shows the Android guy next to an unwrapping package. This lasts only 2 seconds, then it reboots itself again and goes into normal phone mode (where all the app-crashing starts again).
I have not flashed or rooted my phone before, but I will consider this now since my NS is pretty much a brick. Thank you for your swiftly response.
Edit: Shouldn't I get a menu, when I push and hold vol- button, while turning on the device? Right now it just boot as normal.
Before you use odin....try going into rom manager a reflashing clockwork! Ive had that android dude on my screeen but reflashibg via rom manager always fixed it. Try that
Sent from my Nexus S using XDA Premium App
Wow my Nexus has totally shut me out.
I cannot use ClockworkMod unfortunately since I am not able to root my phone. It is not detectable via USA (when I use vol+/pwr and connect USB). I am unable to check the USB Debugging option on the phone. Each time I check it, go to home-screen and back to the menu, it has de-selected it again. Also I noticed when I read the info that is sent to Google for all those app-crashes I get, I see SQLiteException and error in an SQLite.java file. So it seems like some database layer is broken.
I read one could copy the ClockWork.img to my phone and use the standard recovery option to flash the img (I think). But when I go into the recovery menu, the file is gone. When I boot the phone again, it has deleted the .img file - eventhough if I copy it to several different folders, they are all gone :-(.
I feel pretty screwed at the moment. How can I else wipe all data?
I'd recommend to check if your device is correctly identified in windows. Missing USB drivers might cause problems. Get the latest drivers and a guide from here.
If you succeed booting into fastboot properly (vol up and power) you can follow this guide. Get the latest cwm recovery.img here.
Last option would be to boot into download mode (vol up + vol down + power + plugging in usb cable) and use Odin from samfirmware.com
--
All options require correctly working USB drivers.
I managed to unlock the bootloader, by quickly turning on USB-debugging (before any processes started to crash) and install the drivers from this post:
http://forum.xda-developers.com/showpost.php?p=6819751&postcount=4
A reboot later, I got this message:
"System UIDs Inconsistent
UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable."
Right below was a button saying "Im feeling lucky" (??)
I installed ClockworkMod using fastboot and tried "Fixing permissions" with no luck. I will try some ROM later on, and hope it will bring my phone back
Normally this error happens when you have a faulty app ruining your system, formating/deleting whole sdcard does usually fix this.

I can safely mount USB-storage and format the whole bunch?
I been sweating over this stupid issue all day now, all I want is a fac-reset :´(

See I'm no expert on this whole thing. At this point I'd just flash a whole new system via Odin. Prolly not the smartest or safest option, but that's what I'd do because I don't know better. If that wouldn't fix it either, I'd return the phone on warranty
I was looking at Odin from the start, since nothing else seemed to be working.
So right now I got started on Odin. Followed the .pdf steps and flashed the bootloader at first succesfully. I was asked to remove the battery and re-connect my NS. Began downloading "pda" and "phone", but at around 10% a big fat red "fail" message appeared and now I just see the Google-logo on startup. I still cant flash any roms via fastboot.
Im too tired too right now, been working with this for 14 hours straight. I will look at it tomorrow evening. Thanks for your help rentaric
Weird, you're not the first one who had trouble running Odin using their guide.
Overall it's pretty simple.
Enter download mode. Vol up vol down and power at the same time while plugging in the USB cable. Start Odin, should show a yellow colored box with a port number. Uncheck everything but reset timer and auto reboot. Unzip the correct zip file from samfirmware.com (check if you got i9020 or i9023 and get the universal Odin exe), apply file from the folder accordingly. Bootloader and bootloader. Phone and modem. Pda and pda. Csc can remain empty (will change carrier info in fastboot).
Double check md5 hash to avoid broken files.

Of course I did not go to bed, how should I be able to sleep with a broken phone .
The firmware suggested on samfirmware.com for my phone, was 2.3.3 and some other version (my phone was 2.3.4.2/GRJ22 or something similar, I suspect that might be the cause. Also I unchecked everything, that might also have been of importance). The flash will always fail when everything was downloaded - it then said something about "remote" and "Loke" and then fail. But as I mentioned, I had succesfully flashed boot.img (2.3.3) thus no boot occured now. I googled the correct bootloader, used fastboot and was booting succesfully again.
I began looking more into the sdcard, as error-messages was leading me this way. To compress 4 hours of investigations into a few lines, it seems as my PBA is malfunctioning as other xda-members have experinced. Only solution is sending the phone to Samsung for a PBA replacement. I purchased the phone in Bestbuy USA and the danish Samsung partners are not too joyfull about this - I will contact Samsung and hope they can help me.
I experinced the exact same thing as this poor guy - http://forum.xda-developers.com/showthread.php?t=993403
Every thing you try to do to /sdcard is worthless.
Formatting (USB/using CWM/using adb shell linux commands) says "Succes" but nothing happens.
Copying files says "Succes" but nothing happens. If I boot phone into CWM, mount usb and upload new rom/apk/whatever and try to do a "install update.zip" it fails with some mounting errors.
Im ready to go cry in a corner - I really want this to be fixable via software, but I probably have to realize that this is a hardware issue.
Apparently Samsung doesn't offer worldwide warranty for cellularphones :´(. God it sucks to pay repair-expenses on a 1 month old mobile.

[GUIDE] Unbricking your O3D

Hi to all,
Been here for a while and every time i log here in XDA (O3D forum), I always see new people bricking their newly bought O3D (stuck on LG Screen..., rebooting only to cwm recovery.., etc..etc..). If you got into a situation just do the search thing before posting a new topic which is already been posted because our forum (O3D Community) is still small so searching wouldn’t be a problem and there’s no need for a dig yet when reading all the topics posted here. All i can say is for all the people who just bought O3D always remember this "If it aint broke then don’t fix it" you will just end up voiding your warranty,
if there’s an update don’t try to push it on your warranted device, try to check first if the update is applicable to your device (country or region) because we all know that LG only released O3D in Europe so if you are in that place and check that your devices have an update, go grab it, but when it fails always call LG Europe (because you have a warranted device and they will assist you) and explain to them that you are experiencing difficulties in updating your unit, and for everyone else who is not in Europe (like me were my unit is not warranted)be very careful if you want to forcefully push that update to your unit (v10b, v10d or even cwm 4.0.0.9) because me i already bricked my device 3 times were i end up booting only in LG and nothing follows, the other is booting only to CWM again and again, and the last one is after unbricking the device and setting everything then when rebooting the unit it will end up stuck at the LG original android recovery system <3e>menu.
Note: Do this procedure at your own risk, i repeat "AT YOUR OWN RISK", its your unit so its your responsibility, you've been warned, i myself grab that risk and now I’m happy with my unbricked O3D (v10d July, 8, 2011 with fully working CWM 4.0.0.9), all the tools we need are here at XDA so there will be no problem getting those tools.
Ok enough about nonsense(hahaha), lets go down to business. As what the Title says, here we go.
Requirements:
This method will only work in WINDOWS XP MACHINE, i have tried it in Vista and Windows 7 but it will just hung.
I assume that all the necessary drivers are already installed from your machine because without them you can’t bricked your O3D. If by any means you don’t have it, just grab it from http://www.lg.com/uk/support/mc-support/mobile-phone-support.jsp and click the download link save it then run it after installing, it will run automatically, then do the following:
1. Go to Customer Support ---> Application, Manual & USB Driver Download.
2. Enter you IMEI then click the Search button.
3. After Searching, it will list two files form the File List, double click any of those file (me, i choose the file with divX converter)
4. After downloading, it will extract its content to C:\LGP920
5. Go to this directory C:\LGP920\USB_Driver, and double click LGUnitedMobileDriver_S4981MAN33AP22_ML_WHQL_Ver_3.3
6. Let it finish then if it ask to restart your pc, do it.
7. Optionally you can install the LGPCSuite, it can be found in c:\LGP920\LGPCSuite\, just double click the LG_PCSuiteIV_Setup.exe and follow the instruction.
Now that we have installed the drivers for O3D, we can move on to the next instruction.
Make sure to follow the instruction carefully and proceed if you know what your doing.
I have edited nikhil4186 and victortangocharlie post (Original thread: http://forum.xda-developers.com/showthread.php?t=1060121)
1. Detach all other peripherals from your PC. Exit all running applications on your PC especially other PC suites if any. Also exit running programs from the notification bar on the desktop. (Also uninstall Nokia or other phone drivers & microsoft visual ++ runtime environments - not an essential step.)
2. [IMPORTANT] Disable 'LGE Virtual Modem' in PC's Device Manager. (In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.).
3. Remove the Micro SD from your O3D.
4. Download the KDZ rom v10b_00 posted by Fab985 : http://forum.xda-developers.com/showthread.php?t=1155874
(v10d_00 is already available but this method is only tested with the v10b_00 rom, so if you wanna try your luck, its up to you)
5. Download the KDZ updater - http://forum.xda-developers.com/showpost.php?p=8651505&postcount=1
6. Extract it, then run the msxml.msi
7. Now the next step will be crucial because you need a full battery (for safety of course if you don’t want your unit to die while in the middle of the unbricking process) and you will put your unit in emergency mode (by pressing the power button and the volume up button), here’s how you will do it.
Case A. (This is my Case)
If your O3D can boot but only in CWM, charge it (me, i charge mine for 3hours in cwm), you wont see a charging status but you will feel your battery getting warmer.
Case B. (Never happen to me)
If your unit is just stuck at LG logo, try to charge it too and see if your battery is getting warmer, if not, better find another way to charge your battery or a friend who has O3D and borrow the battery.
Once everything is ok proceed to step 8.
8. Open Device Manager and under Modems check if you really disable the LGE Virtual Modem, if it is already disabled don’t close Device Manager, we will need it on the next step. Make sure you can see your Device Manager window and your modems devices are expanded (were you can see the disabled LGE Virtual Modem)
(THIS IS THE TRICKY PART AND YOUR O3D WILL JUST STAY BLACK SCREEN)
9. Plug your USB cable to your pc and then plug it to your phone then enter Emergency MODE (power button plus volume up button) This step is very tricky (me, i tried it several times before it detect my O3D as LG USB modem).
First when your pc detects your O3D, it will detect as OMAP4 then it will look for its drivers, just cancel it, then another device will be detected, if you successfully entered Emergency mode, your O3D will be detected as LG USB Modem, this modem should stay, if it disappear then you failed to enter the emergency mode correctly, try it again before continuing to the next step.
10. Run KDZ_FW_UPD.exe from the extracted folder.
11. Put the following settings:
Type : 3GQCT PhoneMode : DIAG
12. Under the KDZ File, choose the KDZ file you've downloaded from Fab985 post (v10b_00)
13. Press the Launch software update. (this part will take time because it will extract the kdz file into cab file, it took me 15 to 20 mins before it proceed to the updating process)
14. Once updating has started you will encounter this message:
CDMA: wPrama = 2004, IParam = 1
Model Dll Msg Not Found(2004, 1)
This message will come out from 1 to 100 counts:
CDMA: wPrama = 2004, IParam = 1
Model Dll Msg Not Found(2004, 1)
CDMA: wPrama = 2004, IParam = 2
Model Dll Msg Not Found(2004, 2)
And so on till:
CDMA: wPrama = 2004, IParam = 100
Model Dll Msg Not Found(2004, 100)
(Note: This message is case to case because i experienced diff counts then the LG USB MODEM disappear from the device manager list, first attempt count 64 then LG USB Modem disappear from the list, the kdz flasher stops from count 64, waited up to 10 minutes but nothing happens so tried it again from the enter emergency mode step, second attempt count 76 LG USB modem disappear but after a while kdz flasher still continues up to 100 counts then it stop there, waited for 5 minutes nothing happens so decided to remove my device and turn it on and viola it booted to LG original Android system recovery <3e>)
15. After you reach the 100 counts, the process is done, the LG USB modem from the Device manager will be gone, but don’t remove yet your phone to reboot it, try to wait up to 5 minutes before disconnecting your phone.
16. Turn on your O3D, if it boots in LG original android recovery, just choose the wipe data/factory reset, then reboot system now. Then if it is successfully booted to android continue to setup your device but after the initial setup, don’t install or do anything yet, reboot your device again then see if it will reboot back to android, if yes, you’re done, your O3D is again alive and don’t bricked it again, if not proceed to step 17.
17. If it comes back again to recovery after booting then wipe data/factory reset, wipe cache partition then reboot system now.
18. Turn on your O3D, then if it is successfully booted to android continue to setup your device but after the initial setup, don’t install or do anything yet, reboot your device again then see if it will reboot back to android, if yes, you’re done, your O3D is again alive and don’t bricked it again, if not proceed to step 19.
19. If it comes back again to recovery after booting then wipe data/factory reset, wipe cache partition, and lastly wipe nv dynamic partition then reboot system now. (this part resolve my rebooting issue)
20. Turn on your O3D, then if it is successfully booted to android continue to setup your device but after the initial setup, don’t install or do anything yet, reboot your device again then see if it will reboot back to android, if yes, you’re done, your O3D is again alive and don’t bricked it again, if not I guess it’s the end of the line for now.
Sorry for this very long instruction. If it helps you I don’t have a beer fund because I’m not a dev. but a simple hit with thanks will do.....
TIPS NOT RELATED TO UNBRICKING:
Rooting:
Run SuperOneClick as Administrator, before clicking Root, click first the Driver Check and if no problem has been detected, no more settings is required just click the Root button then wait until it says done or finish.
ClockWorkMod:
After rooting, download rom manager from the market, after the install run it and tap Flash ClockworkMod Recovery (4.0.0.9), once successful you may now backup your current rom before you mess again with it, since I installed cwm in my O3D I never use the buttons to boot with it(power button plus volume down button), I always use the menu's with the rom manager to boot into or backup or restore or flash in CWM.
Upgrading:
For safety purposes, if you have a warranted device and then an update pops out, always do a fresh start, what I mean is if you already rooted your device and installed CWM, better removed it first before updating your O3D so when things goes wrong from your update process you can always call LG for it to be fix eliminating the needs to post something like “Help I brick my O3D and I can’t bring it to LG because I installed CWM blah blah blah etc.. etc…”, got the point so be responsible.

Did you follow the whole step, I know its a long process and it work with me, just follow everything and when you are in step 9 were you need to enter emergency mode,its a tricky step,make sure LG Mobile update is not running completely,open your pc device manager and expand the modems,try to remove the battery then press volume up and power button, put the usb cable then put back the battery,it will vibrate then your xp machine will detect it as omap4 device just cancel it but don't de-press the volume up and power button,then after a while it will vibrate again check if you see LG usb modem in the device manager,once you saw it and it stays,it means you successfully entered emergency mode then that will be the time you will run the kdz flasher and follow the succeeding steps.

I have bricked my phone numerous times, and in many imaginative ways. The above instructions are pretty much what I do whenever it gets stuck in some non-functional mode.
I tried this way like 30 times during the last week, I just got back from holiday and I just tried it on a Win XP machine and it's always the same it flashes and it never reboots, V10B/D doesn't matter... After flashing I manually power it on, and only get the Firmware update screen and it hangs there forever... I called LG today waiting for a replacement.
@aremcee
Sir thanks for confirming that this method really works.
@wuper @renegade_rulez
Are you doing it in xp machine, if you run it in Windows 7 the process will just fail. Only disable the LG virtual modem from your pc device manager and completely exit LG PcSuite and LG Mobile update. Make sure your xp machine detects your O3D as LG USB MODEM and not omap4 device, the detected LG usb modem should stay in your device manager under modem and it should be enable then you can now start kdz flasher. Will try to investigate what causing your O3D not to flash using the kdz flasher and if I have time will upload a video on how to properly enter emergency mode.
@all
Thanks for reading this, if you have a question just post it here and will try to answer it back as knowledgeable as I can.

if you can try this and make the phone work that means we are doing sth wrong:
1) install clockwork via rom manager
2) install update via settings telephone software update
3) after installing this update the phone stuck at clockwork recovery and all reboot is turning to this screen
4) flash 10b or 10d through kdz or lg mobile, it will stuck at firmware update screen as picture shown as attached
we try as u said on xp machine several times and device manager opened lg usb modem was there till the process finished after that it get lost and I waited 5 minutes and exit kdz and start manually, nothing..
(the attachment picture is turkish, it is written firmware is updating above and the phone will restart after finishing firmware update below)
PS_U_A_John stated in other topic he can flash a phone that is clockwork installed, that shows clockwork is not the problem, I think clockwork and our installed phone update and after flashed kdz rom are colliding each other and phone could not restart.

Hi wuper,
Can you try after flashing then turn on your device to recovery by pressing volume down + power button, or remove your battery then put it back while pressing those buttons, will it go to android recovery system <3e>?, if yes try to wipe everything then reboot. let me know. thanks.
Like wuper just told, mine is the same... It's not fixable in that way. Again this morning I tried on my XP pc and it's always the same. Just called LG again they will replace it within 24h we will see
update:
You cannot get into the recovery system, holding power + volume down the phone will power on and off again, releasing power when it boots and keeping volume down pressed gets the Firmware update screen.
same for me cannot enter recovery
Hi, I had a bricked optimus 3d, after the installing the cwm recovery I couldn't turn it on, it would always go into the cwm recovery, no mater how I turned it on.
So I followed your "how to" on an xp pc, and I was able to flash the v10b fw.
Everything went like you described it: the counter reached the 100, I waited about 6minutes after that to turn it on, after that it would go straight to the android factory recovery (the one with the blue letters), and to phone won't boot up.
So I made a factory reset, than reboot, but nothint happened, then factory reset and wipe cache partition, than reboot, but I was still getting the recovery.
Then I made a factory reset, wipe cache partition and wipe nv dynamic partition, and then reboot, but the phone instead of rebooting turned itself off.
I turned it on, but it said, that the battery was almost empty, and needs a recharge (strange, because it was fully charged).
I pluged it on the charger, and the sign of a totaly empty battery was showed.
I left it for a couple of hours and the hole night, but the empty battery sign was still there.
I tried to turn on the phone, it booted up normaly, everything was ok, the phone was working again, but the battery was completely empty.
I bought 2 original replacement batterys, but the result is still the same.
So, can someone help me what went wrong, why does any battery work?
Why won't they charge?
I think that it has something to do with the last item I wiped, the nv dynamic partition, because after that the phone hasn't rebooted, but turned off.
What sould I do?
And no, unfortunately I don't have warranty on my phone.

Hi Zirowe,
Hmm thats strange, you and dnardz have the same problem, wiping the nv dynamic partition solved my rebooting issues and didnt experience this battery not charging problem, try to root your phone and install clockwork recovery 4.0.0.9 then reboot to cwm and full wipe your O3D including the battery stats, then charge your phone again and see if it is charging(maybe two hours), if it still doesn't work, download the v101d cmw rom by PUAJohn and restore it. Let me know

-Re-insert battery
-do a hard-reset
-boot up device completly
-Turn device off
-plug-in charger (NOT USB-PC)
-Wait 1 hour

Tricky: Optimus One stuck at LG logo

Hey guys,
I got a little problem here and would appreciate any help. As you might have guessed from the title I have an Optimus One here that won't boot. It is stuck on LG logo screen. The phone is not mine but my father-in-law's and I told him I would have a look since his warranty is already void. He told me that he turned it off because it was gettin really slow (and he does that from time to time to clear memory) and as he wanted to turn it on again, it was stuck on LG logo. And has been since. I can still access emergency mode though, but that's it!
Now, I know that there are a lot of threads that treat this problem but in every one of these threads people solve the problem by flashing a stock ROM via KDZ. And that doesn't work for me. It just won't go through with the whole process. I'm flashing in emergency mode and always at some point you hear the sound indicating that a USB device has been unplugged and it starts to boot (I don't know if it is supposed to cause I've never had one of these phones in my hand that was working properly, only this broken one) but obviously gets stuck at LG logo. After a while I get an error from KDZ and thats it.
I also tried with LGMDP, which didn't work either. And obviously I tried a hard-reset, which didn't do anything.
I really don't know what to do with that stupid thing. But I am 100% convinced that it can be revived because emergency mode is still accessable.
Can any of you guys help me? Would be much appreciated!!
Cheers
Hard reset!! again...mb try to flash CWM and wipe data/cache/dalvik
Hard-Reset doesn't work. Just leaves me at the lg logo again. How do you flash CWM? You mean with LGDMP?
tried it, didn't do anything. Thanks for the effort though...
No. KDZ
I`ve broken CWM and killed my O1. And just flash CWM via KDZ and reflesh ROM. It helps me
@ElZeck, when you are flashing with KDZ, what is the error that you get? Also, what is the operating system on your computer? I think I had trouble using KDZ on Windows 7/8, but Windows XP worked just fine. Maybe you might want to try using KDZ on a different computer.
Hey guys, thanks for your replies!
@Kill4File: How do you flash CWM with KDZ? I tried with LGMDP but I wouldn't know what file I would need to do so with KDZ. Can you supply the file?
@sweetnsour: I don't recall the error exactly. I know it ran through parameters until 100 twice and then it got stuck at sth. like wPrm 8. That sound familiar to you? OS is Windows 7.
Just download a recovery like cwm or twrp, then extract the .img file and flash that through lgmdp.
Edit : if you start your phone what happens?

I remember my friend bricking his LG Mytouch, so I tried to help him out with KDZ. I believe you got a similar error (and he was also using Windows 7). I think looking for a different computer to use KDZ on might be the key, especially if you find a Windows XP computer. Basically Windows 7 caused trouble for my friend and me, and Windows 8 wasn't any better. My old XP desktop got the job done though.
This is what I do when I use KDZ (don't miss the words in bold):
1. Manually boot your phone into emergency mode, with emphasis on manually. To do so, hold Back + Vol Up + Power.
2. Plug the cable into the computer first, and then the other end into the phone, in that order. I know some people are used to plugging the cable into the phone first and then into the computer, but sometimes (at least when the phone is normally booted) the computer doesn't detect the phone.
2a. Just making sure, I assume that since your computer at least began the KDZ flash, you already have the drivers for your phone. If you do decide to try it on a different computer, remember to install the drivers (reasons on why I use Windows XP in the next step). Also, don't forget to disable the LGE Modem in Device Manager.
3. Open KDZ. I don't know why KDZ causes issues for me on Windows 7/8, but on those two operating systems, I get some sort of "compatibility issues." Also, KDZ likes to crash in the middle of a flash. Never had any of those issue in Windows XP (no crashes, and I believe KDZ was built for XP anyway since there aren't any compatibility issues).
4. Make sure you have it set to 3GQCT and DIAG. (If KDZ fails to flash, try the different options under PHONEMODE and also try shaking your phone during the flashing process). Browse to your KDZ file.
5. Begin the flashing process. No matter what happens on your phone (it reboots, makes noises, etc) don't remove the cable until KDZ reads "FINISHED".
6. If the phone fails to boot properly (stuck on bootanimation even though it flashed properly), yank the battery, and hold Home + Vol Down + Power. This will begin a hard reset.
If this is what you've been doing on Windows 7 and it still fails, I highly recommend using Windows XP.
Hopefully that helps

Unfortunately, I can't! Only emergency mode is accessable. Anything else (recovery, hard reset,...) leads to LG logo screen.

I had this. I took out the battery, replaced it and then plugged into the USB. Got charging screen. From there, adb reboot recovery, restored a backup, and got back up and running (assume you have a usable backup available).
Here is a way to revive your phone
If you can enter recovery mode,your phone is revibable.You can install CyanogenMod 7 Android 2.3.7.
First,you need to download CM7 ROM.
Then download Google Apps.
After you download these files,put your sdcard in other phone,then connect to computer via USB cable.
Transfer the downloaded zip files to sdcard.
Insert your sdcard in your LG Optimus One.
Put your phone into recovery mode(ClockWorkMod recovery is required).
Use Volume buttons to navigate and Menu/Search key to select.
From the main menu,select mounts and storage>format/system.
Also select format/data and format/cache.
Go to main menu and select wipe data/factory reset>yes.
Now,select install zip from sdcard>choose zip from sdcard and select downloaded zip
Also,install Google Apps.
Reboot your phone.
You'll see the LG logo,Don't Panic!Wait a few seconds,and the CM boot animation will appear.
First boot takes some long time to install updates.
You're done!

[Q] Hi and n00b needs help

Hi all nice to be here have had a good look thru forum and i reckon its the place for help
Please bear in mind when replying...yes I am a noob and a loser and yes my mum did say i am special ...
Anyway here goes
Have(had) a p920 on 2.2.2 and upgraded to 2.35
got a bit over excited and decided i wanted more so like an idiot i tried "jellybam" didnt back anything up and JB has made my phone pretty much unusable for anything except as a wedge under my car front wheel to stop it rolling down the drive (the handbrake isnt holding that well)
If i could i would just go back to original but i have no back up and I have read your forum and i do not understand all the cm10, ICS etc etc references
Could anyone give me a guide on how to make my phone usable again (i have cwm installed) and could it be in words phrases i understand
Thanks folks
Hi.
I would recommend you to try and flash the latest firmware with LG Mobbile Support Tool.It's not that hard and you can't do anything wrong with the phone so don't worry.
Start the app, install the driver for your phone(you'll have an option for that on your right), connect the phone and if your phone gets detected you'll have an option to upgrade to v30(that's ICS and it's faster and better than GB).
This way you'll flash ICS but you'll have all your data,sms,apps etc from your previous rom.
If that doesn't work for you, follow this tut and you'll be on Xbsalls V8 rom that's prerooted ICS rom with TWRP custom recovery(TWRP is also recovery, like CWM).
http://forum.xda-developers.com/showthread.php?p=39269819
I use this rom and it's very good.
Anyway you can flash some other rom in TWRP if you don't like it...
But ALWAYS BACKUP YOUR ROM BEFORE FLASHING ANYTHIIIIIIING.
We all learn that the hard way...

posted a couple of pics not sure if it helps incidentally when i connect to the pc it only connects as a media device not sure if that tells you anything, would love to get this phone working again as its literally been in the box from new until a few days ago

Hi.
I would recommend you to try and flash the latest firmware with LG Mobbile Support Tool.It's not that hard and you can't do anything wrong with the phone so don't worry.
Start the app, install the driver for your phone(you'll have an option for that on your right), connect the phone and if your phone gets detected you'll have an option to upgrade to v30(that's ICS and it's faster and better than GB).
This way you'll flash ICS but you'll have all your data,sms,apps etc from your previous rom.
If that doesn't work for you, follow this tut and you'll be on Xbsalls V8 rom that's prerooted ICS rom with TWRP custom recovery(TWRP is also recovery, like CWM).
http://forum.xda-developers.com/showthread.php?p=39269819
I use this rom and it's very good.
Anyway you can flash some other rom in TWRP if you don't like it...
But ALWAYS BACKUP YOUR ROM BEFORE FLASHING ANYTHIIIIIIING.
We all learn that the hard way...

Tried that guide but unfortunately step f5 never happens and if i then go onto 2j the flash never writes and bums out after 20 odd seconds

Did you use the right KDZ or extracted files (with the DLL file with same model as what's printed on IMEI sticker after pulling out battery - like "MODEL: LG-P920" for example)? I had the same problem. Wrong DLL usually cause that.
EDIT: Is your phone P925 (aka AT&T LG Thrill 4G)? If so, I have P925 DLL. Also try flashing V21D/E or V28 baseband.

Thanks again m8 but i daren't use that guide, i really appreciate the author of its work but its so anmbiguos as it doesnt really explain clearly when you should remove cables etc etc for example
step 9 connect your phone using the usb cable
but by step 12 connect your phone using the usb cable
I am not exactly clear when i was supposed to remove the cable that was put in at step 9
I have caused so much hassle already that if i can find someone in the uk who is not a complete retard at this like me i would happily pay them to fix the phone

Step 8-unplugg your phone??
Anyway, all the tuts are just the pointers.Try and see and if youre stuck at some point, come back and ask.(but in the thread of that tut that you're using)
Just reading isn't going to take you anywhere.
By the way read thoroughly before doing anything...
I was a giga mega ultra noob before I started playing with my phone and now, few months later and more thatn 10roms later(with a gazillion bootloops and softbricks) I know what I'm doing..
Everything you need is in this forum and belive me if your hardware is good,your phone is fixable.
Xbsall and the others made sure of that.
Just relax and folow the first link that I gave you, the drastic00's guide to V8.
It's the best way I think...
Cheers.

Sorry m8 not trying to diss that poster but truly its not clear at all and i have tried and tried all the parts and it just doesnt happen
step 8 unplugg your phone??
step 9- Now pull out battery, hold vol-up and connect your phone using the usb cable <----so phone is now plugged in
step 10- Your phone should be now in fastboot mode <---- no reference to unplugging phone
step 11- In device manager, you will LG COSMO, install now it's driver which is included in OS_HACKING package. <----no there are NO drivers in that package
step 12- Now one more time run OS_HACKING tool, hold vol-up and connect your phone using the usb cable <plug your phone back in? Sorry i didnt know i was supoosed to unplug it
step 13- Flash the GB bootloaders then flash CWM recovery <--------I have no idea what these are or how to do as there is no reference to them previously in this guide
As i said i rerally appreciate any help but that guide just doesnt make it clear enough for a complete doofuss like me
Tries this guide too http://forum.xda-developers.com/showthread.php?t=1942836 but no joy
Its weird cos I can boot to cwm and install a jellybam rom from an external sd card but I cannot successfully install any other rom from it (i am not sure if just doing the wipes then installing a rom downloaded from this site is the right thing to do.
Thanks again

You can find the drivers for LG Cosmo in wsParks omap4boot: http://d-h.st/U08 (i took this link from the resurrection guide).
Afher you instal this important driver.
You can open the omap4boot.
Just type a 2 and connect you phone to the usb.
If text is scrolling in the interface, plug in your bat and hold vol up.
You will enter normal download mode and ready to flash with LG flashtool/smartflash.
Hi thanks but i just got as far as this in the guide, the phone rebooted set itself up and seems to be working fine, without wanting to screw it up anymore, can i just not leave it as is, everything seems to be working wifi, sim etc etc do i actually need to do what it says in the rest of the guide ? added a pic cos am not clear about baseband stuff etc
A) Install LG Flash Tool by running "Setup_LGFlashTool_1.1." Let install but uncheck the ‘open LG Flash Tool’ box (don’t run it yet). The package comes with version 1.2, but 1.1 is what I used.
B) Copy the file ”LGFlashTool” from the “FILE.ZIP” folder over the file of the same name into the ” LG Flash Tool 1.1” folder. This will unlock the program.
C) Right click on "LGFlashTool," found in the same folder you just copied into and choose "Run as administrator."
D) Check the box that says "Select Manual Mode."
E) Click the "..." button to the right of the "DLL" field, then choose "LGP920_110622.dll" file you downloaded. This file helps Windows to write the correct information to the phone.
F) To the right of the "S/W" field, choose "Add" and navigate to/select "28bROOT_AP.bin." This is the official ICS file, but with root access and TWRP recovery.
G) Be sure the button for "USB" is selected. Click OK.
H) Choose the port settings icon that looks like a serial cable.
h1) Check Port 1.
h2) It should select the first 3 check boxes when you do this; "16 Ports," "Port 1 ~ Port 16," and "1" should be checked.
h3) Click OK.
I) Click the yellow arrow (start). You should see "Ready!" at the top left.
J) Insert the battery into the phone. While holding the volume up button on the phone, connect it to the pc with the sync cable. The phone should start flashing (i.e. LG Flash Tool will start writing the file). NOTE: if Flash Tool will not connect, try holding volume up, connecting the USB/sync cable, and THEN connecting battery (while holding volume up). Don't touch it until the process is complete. The phone will boot up. Once it boots up it is OK to disconnect the phone
K) The phone will NOT boot up completely. There will be a message about factory reset (but the button will not let you proceed), or the phone may stick at the LG logo. Long press power to shut off the phone. Hold Volume down + Power. Alternatively, try Home (i.e. house on keypad) + Volume down + Power. You should get a text screen about factory resetting. Press power twice to confirm. Let it reset and boot up.<--------------------------------------- GOT TO HERE SUCCESSFULLY :laugh::fingers-crossed:
L) Set up the phone. Then shut it down again.
M) Next we will flash the baseband (.fls) file. Redo steps 2C through 2J. But replace "28bROOT_AP.bin" with "28bROOT_CP.fls" in LG Flash Tool. The process of flashing a baseband will NOT complete to 100% in LG Flash Tool. That’s OK. I got to 155 seconds and it worked.
N) If you have connection problems (the 28b baseband is working for me), you may want to get another baseband from here: http://forum.xda-developers.com/showthread.php?t=1974734. Download the file you need and repeat steps 2B through 2J with your preferred file.

Sounds like you did it.
If you dont have issues with 3g or calls, you dont nessesery have to flash your baseband.
But in many times it will be better you do.

[Tutorial] How to unbrick T-mobile LG G2 D801 stuck in DemiGod Crash Handler screen

Try holding the power, volume up, and volume down buttons all at once with the cable disconnected. Might need to try this a few times as it doesn't go into download mode every time.

I just went through this after being without my G2 for nearly a year. Luckily, I had other devices but still; I really like my D801. Anyway, I'd flashed a bad bumped bootloader that landed me in "Demigod Mode"; didn't have a PC until I fixed mine this week, and was determined to get the LG up and running. I tried different versions of flash tools, LG's Mobile Support & PC suite, fumbled with the drivers, which in the end is key!
If you're connecting your device to your PC and see QSUSB_BULK as one of the attached devices in Device Manager - assuming you're using a Windows PC - you need the SRK Tool found here:
http://forum.xda-developers.com/lg-g2/general/choise-unbrick-qhsusbbulk-qualcomm-9006-t3093844 because it's likely - as in my case - all your device's partitions have been nuked and you won't be able to get into download mode no matter which combination of key presses you try. Follow @somboons guide. Use his thoroughly amazing, brilliant SRK Tool. He's the real demigod when it comes to LG devices and his tool couldn't be any easier to use. He's done all the hard work, gathering the different partition maps for just about every LG device in existence and I swear by it since my D801 is up and rocking and only because I never gave up.
There are truly gifted people here on XDA that deserve our profuse thanks and so much more for all they do for this community. The task - and the tool - may seem daunting at first, but you'll find it really couldn't have been made any easier so do give it a try.
I mean no disrespect to the OP, but this is what worked for me and I felt it important enough to share for others going through the same situation.
We have the same phone, maybe different revisions (30b ? Mine is 30c). Encountered the same problem. The phone isn't really "bricked". You should still be able to boot normally. It's just the recovery that's trashed.
I induced this problem by running Flashify while SuperSU 2.65 was misconfigured. Flashify will gleefully go about it's business even though SuperSU may be misconfigured.
Here's the fix:
1. Don't use Flashify (or similar tools), prepare to install TWRP via Autorec. This will install TWRP 2.8.6 which is a fairly current version.
2. Under SuperSU 2.65 settings uncheck the "Mount Namespace Separation" box and reboot.
3. Now run Autorec. TWRP will be installed without any problems. I recommend QuickBoot to conveniently boot the TWRP recovery.
This is the shortest path to getting TWRP installed. Its big advantage is that you don't have to explicitly muck around with unlocking the bootloader, Autorec takes care of that for you behind the scenes (via the Loki patch). The author of Autorec cited a problem with Autorec not running in the presence of SuperSU 2.6x. That isn't true, it's simply the settings change I pointed out above. I have contacted the Autorec author about this, he agrees with me, and hopefully will update the Playstore Autorec description as his SuperSU 2.6x warning is creating a lot of unnecessary confusion and misunderstanding.
Enjoy TWRP. I look forward to checking out the CM ROM.
cheers.
This worked for me, great!
Thank you
