Well if you took a bunch of ota updates then you have fastboot. If you downgraded then you probably have adb and fastboot set up on your pc. But this will ONLY work if you downgraded and got fastboot. If after trying the reboot bootloader command you just reboot. You gotta use lgnpst
open windows command prompt type
Code:
cd c:\froyo\androidsdk\tools
this is only the directory of you downloaded froyo.zip from the 2.2 root guide. If you didnt find adb.exe and fastboot in the android sdk directory and put that directory after the cd command.
Once the active line shows the directory where adb and fastboot are enter
then while the phone is bootlooping plug it in and enter
the phone will reboot into fastboot, blue screen. This may take a few tried to catch it in the right spot, you can usually do it towards the end of the red vzw splash
If it just reboots then you didnt downgrade or you updated wuth lgmu, but it sounds like you DO have fastboot.
Now download the latest amonra recovery and move it to the same directory as fastboot and adb. I would rename it recovery.img to save you some typing in command but if not you would just use whatever its named. Now enter
Code:
fastboot flash recovery recovery.img
to flash the recovery OR
Code:
fastboot boot recovery.img
to boot straight into recovery and flash velocity from there which will then flash amonra recovery to the phone.
