Method 1 (Try this first):
  • Pull battery
  • Insert battery
  • Hold volume down+home+power until you see recovery menu

Method 2 (For noobs):
  • Download this: FastbootOV.zip
  • Extract it
  • Install drivers
  • Connect USB
  • Open cmd.exe
  • Type these commands:
    Code: 
    fastboot erase boot
fastboot erase recovery
fastboot erase data
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash data rom.zip
fastboot continue
  • If it is offline charging, power it on.
Method 3 (For those who know what they are doing):
  • Install drivers
  • Plug phone to USB
  • Get mini-sdk in this post: http://androidforums.com/faqs/443072-adb-guide-updated-12-05-2011-a.html
  • Extract it
  • Get a ROM> Extract boot.img> move it to same folder as fastboot.exe
  • Move ROM to same folder as fastboot.exe>Rename it to rom.zip
  • Get a recovery(BobZhomes or CWM-Green)>move/extract to same folder as fastboot.exe and rename it to recovery.img if it is not called that already
  • While holding shift key, right-click the folder that fastboot is in>press Open command window here.
  • Type these commands:
    Code: 
    fastboot erase boot
fastboot erase recovery
fastboot erase data
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash data rom.zip
fastboot continue
  • If it is offline charging, power it on. If you flashed an ICS rom, unplug and power it on.

Enjoy :)
 
when i type "fastboot flash boot boot.img,
fastboot flash recovery recovery.img, or
fastboot flash data rom.zip, it says cannot load. Please help
 
For now try using the full SDK folder found in the same place you found the mini SDK. Scroll down until you see the "Pre-Packaged ADB Installer". Delete the mini first
This will take only ten minutes at the most to establish the adb.exe into the system path of your PC (if for some reason you don't get the proper output after typing in "adb devices" follow the instructions just below that, in the tutorial).

Then make sure the recovery is not zipped,extracted it if you have .zip on the end (if you see .img your good).

The fastboot.exe is located in the platform-tools folder.

Also: You can get there in a command prompt pretty easy just by typing in:
cd..
cd..
cd SDK\platform-tools
 
But i already have the sdk installed and adb is already in my path the only problem is the command prompt the first three codes work and the last three don't

You didn't put stuff in the correct folder. Also rename files properly.
 
Something else that might come in handy later:
Using a Root file manager like ES File Explorer, extract the PlayStore.apk onto your PC and place in the platform-tools folder. It is located in the /data\app folder and is labeled this: com.android.vending-1.apk. Copy and paste to the sd card, then when you plug the phone into PC copy it into the C:\SDK\platform-tools folder.
Then if for some reason you ever loose or accidentally delete it, all you have to do is plug your phone into the PC and type in:
cd..
cd..
cd SDK\platform-tools
adb install com.android.vending-1.apk

I have read of it happening a couple of times to other members and just had it happen to me (oops).

But the recovery, rom , and and boot.img are in place and for some reason they come up on my windows 7 as disc images.
I put them in the platform-tools folder.
 
Did You leave the ROM zipped? It should stay zipped and have .zip on the end. Recovery and boot should be unzipped with .img on the end

Edited mistake out

Yea windows 7 does that, only to .img files .......I have a feeling you still renamed it wrong, delete ".img" from it and try again with same command line

OP updated, follow method 2 again. If it still errors, I will do it myself trying to see what's wrong.

Just to let you all know, method 2 uses CWM-Green recovery with JerryScripts BACKside ROM and boot.img is from that ROM.

Ok im in the recovery and i itnstalled a stock rom from my sd card and i rebooted but its still taking me into the recovery
 
Jerry's Recovery doesn't have the fix recovery loop option, right?

I'm pretty sure it doesn't. If this is the case:
Download the Xionia recovery in a zipped form and flash it like you would a ROM, then once done go to the advanced section and select "reboot recovery". This will boot into the Xionia which has that "fix recovery loop" option in the advanced section.

The zipped Xionia can be found here: [FIX]Black screen with custom recovery and custom roms - Android Forums at AndroidCentral.com go to the bottom of the first post to find the link.
 
Thanks for all your help guys i finally unbricked my optimus v. you have to flash Xionia recovery in order to flash a rom u cant do it from the cwm_green recovery.
 
Thank you sooo much!! This fixed my OM!! Did everything it said EXCEPT for erase rom and flashing the new rom. The DATA parts anyway.. Once I type fastboot continue, it took awhile saying "bad page errors" then eventually it booted into recovery mode. just clicked reboot phone and poof it works :) thanks!!
