As promised here is a beta amon ra style recovery for opt1 thunderg.
Its untested as I don't have one to test it on.
Key mapping is up/down = vol-up and vol-down
select = power
backup = search
If the keys aren't right use the key code debugger under "other" menu and give me the key code outputs.
Fastboot IF enabled on optimus one can be accessed by "adb reboot bootloader".
The best way to test this if you have fastboot is to do
Code:
fastboot boot recovery-thunderg_test1.img
if done this way it will boot from ram and will be lost upon reboot. IE. its temporary if it needs some changes instead of actually flashing it.
If you need help setting up fastboot/adb drivers reference my post here for the Lg Ally

It should either be 618e or 618f for adb.
If you don't have fastboot on device this will flash it:
Do this from a su (root) adb shell (preferred) or terminal on phone after you have copied recovery-thunderg_test1.img & flash_image to root of your sdcard. Flash_image is attached to the post linked above.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/recovery-thunderg_test1.img
Also if you have a file named install-recovery.sh in system/etc you will need to rename it to install-recovery.sh.bak prior to flashing a recovery.
