If you have time and money to make it to the service center, you can go ahead and get LG Optimus V unbricked. Or simply follow the below guide to unbrick your LG Optimus V device. LG Android Phones

Following is a tutorial on how to unbrick a LG Optimus V back from death, but I have a warning. NO ONE should try this. No one. Not ever. Don’t do this. This will brick your phone. This is just for the OP, because his phone will be a coaster otherwise. I cannot stress this enough. No one do this! If you can get into adb shell or your recovery there is absolutely no reason to ever do this! Never ever ever ever ever ever!!!!!
Ok. With that out of the way and the OP wetting him or herself, we can continue. LG Phone Problem and Solution

  1. Download the Optimus V Stock Firmware Cab: VM670ZV4_13.S4_13.P61007.cab
  2. And the KDZ updater: KDZ_FW_UPD_EN.zip – 4shared.com – online file sharing and storage – download
  3. Uncompress the KDZ updater and install msxml.msi.
  4. Make sure your phone is fully charged.
  5. Turn your phone off (by pulling the battery if you half to).
  6. Plug in the USB cable.
  7. Hold down the volume down button, the power button, and the return button (the looping arrow button, not the home button). This is like entering recovery mode, but you are holding the return button instead of home.
  8. This will launch "Emergency Mode". Don’t be alarmed.
  9. Your computer should start installing drivers. Let it finish.
  10. Emergency mode might start looping on and off. That’s fine. It is trying to connect to the software on your computer. Ignore it.
  11. Disable LGE Virtual Modem drivers it installs. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable. (very important not to skip this step!) If there is no virtual modem listed, you may continue.
  12. This is as far as I’ve gone personally. The rest is theory.
  13. Shake the phone. (No clue why. Just mindlessly do it.)
  14. Run KDZ_FW_UPD.exe from the uncompressed KDZ updater.
  15. Select Type : CDMA (If that fails, try 3GQCT)
  16. Select PhoneMode : EMERGENCY (If that fails, try CS_EMERGENCY, or DIAG)
  17. After this point do not turn off your phone for any reason or error! If the falshing fails, just try using different settings from above, but don’t restart the phone!!!!! Maybe you need to shake the phone more.
  18. Pick the Optimus V firmware file when asked to.
  19. Shake the phone for good luck and flash.  LG-Optimus info

Its sad that credit wasn’t given to the person this came from. This is untested and the person who posted it here should of mentioned that. Who ever posted this it is not their technique it is mmarz’s @ android centrals.

Your opening into this is quite rude. “DON’T ANYONE DO THIS, DON’T EVER TRY THIS, DON’T DO IT, IT’LL BRICK YOUR PHONE” blah blah blah. Why the hell do you think we’re here, dammit? Retards..

Here’s a safe and easy way to unbrick your LG Optimus V. Worked like a charm for me.

First, what happened with me was, I was using Xionia recovery and was wiping in preparation of installing another ROM. Under advance, for curiosity sake I hit “LG Style Wipe”, which, from what I understand is just like hitting Factory Reset within the phone in the menu settings. My phone would boot to the screen saying “factory reset…formatting data…formatting cache…do not remove batttery…rebooting”, then would sit at the pink LG logo screen. Could not boot into custom recovery at all, no matter what. Could only boot into Emergency Mode.

I wracked my brain trying to use KDZ, KP500 with LG Utility, while in Emergency Recovery to no avail. So finally, here’s what I did:

What you’ll need is: ROMTools, stock ROM (I made a nandroid backup before I originally rooted), a basic clockwork recovery, and ADB installed on computer.

1) place the recovery in your ADB tools folder

2) prepare a command window: on computer -> Run -> cmd, then start ADB by typing (without the quotes) “cd C:\Program Files\Android\android-sdk-windows\tools” then hit enter (or where ever you installed ADB at)

3) Type (without quotes) “adb reboot bootloader”, do not hit enter yet.

4) Now, here’s the tricky part. Plug phone in to computer. As the phone goes through the Formatting, blah, blah, blah, go back to ADB and hit enter. This may take a few tries. It may say “device offline” or “no device detected”. Just keep trying. This is actually the hardest part.

5) Once your phone reboots into bootloader (blue screen), go back to ADB and type (without quotes) “fastboot boot “recovery-RA-GNM-thunderc-s-1.1.0.img” (or whatever recovery you placed in your ADB tools folder in step 1)…If it fails, just try again. It took me a couple tries.

6) Your phone then should reboot into clockwork recovery. You should now be able to mount your phone as “USB mass storage device” under “mounts and storage”. If computer does not connect try unplugging and plugging back into computer. If it still doesn’t connect, you may need to reinstall LG drivers, which you can do using ROMTools under flash a recovery. but, ONLY install the drivers which it will do first (3 drivers). after drivers install, exit out.

7) Once you mount your phone to computer, put the stock ROM on your SD card.

8) Choose “install zip from sd card” then choose the stock ROM. Unless you have a nandroid backup of stock ROM. In that case choose “backup and restore”, then choose the stock nandroid backup. Once it installs, reboot.

9) The phone will still go through the “Factory reset, formatting, blah, blah, blah” screen, but after it reboots, but it will boot into the stock ROM.

10) Now to get rid of that annoying “Factory reset” boot screen. Once your phone fully boots up, open ROMTools. Type 2 (Flash recovery to phone), then 1 (LG Optimus V), then 1 (install drivers, obtain root, flash recovery), but ONLY install drivers (3 of them) then exit out. If you did this in step 6), you shoot be able to skip this step.

11) Open ROMTools folder and click “one.exe” (SuperOneClick) Once it opens click on “UnRoot”. This will unroot your phone. After it goes through everything it may say fail at the end because it can’t find the busybox folder. No worries, it should be unrooted. I then downloaded Root Checker (free on the market) just to make sure it worked. Exit out when it finishes.

12) Reboot phone…It should now reboot with now problems, just like new.

13) Now you can re-root, flash your custom recovery, then install your ROM of choice.

This whole process takes only about 15-30 minutes. It took longer to re-install everything from Titanium Backup, lol. I spent 4 days trying to figure things out to unbrick my phone, when this simple and quick procedure took such a short amount of time to fix, lol. Not sure why I didn’t try this from the beginning, lol.
