Please do not host these links or how to's else-where and instead direct users to this post as its easier for me to keep up with things in just one place.
Lets start the custom roms!!
To use download & unzip & copy flash_image and recovery-thunderc-m-v1.2.0-GNM.img to the root of your sdcard.
To flash: via adb shell or terminal type this from root # su shell (Do not type the # its for reference)
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
# flash_image recovery /sdcard/recovery-thunderc-m-v1.2.0-GNM.img
1. If you get an out of memory error reboot device and do it on a fresh reboot.
2. If you get a file not found on the "mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak" skip it and move to the next step as this file will not be in your rom unless it has recieved an ota-update and if so needs to be disabled.
Key combo to boot custom recovery from powered off is Vol down+ Home +Power and release at LG Logo or use adb reboot recovery from adb shell.
ADB as root user
USB-MS Toggle :mounts sdcard as mass storage
Nand Backup : runs a nandroid backup of data, cache, boot, system
Nand Backup + .android secure : backs up above plus .android_secure on sdcard (froyo native apps on sd)
Nand + ext backup : data, cache, system, boot, plus apps2sd on ext partition (old style apps2sd)
Nand Restore : browse to and select nandroid backup to restore
Flash Zip From Sdcard: Update.zip must be in root of sdcard or you can directory browse.
Toggle Signature Verify : Turn of signature checking on flashing zips
Wipe data/factory reset: wipes data & cache
Wipe Dalvik cache : Wipes Dalvik cache in all possible locations if moved by apps2sd
Wipe SD:ext : Wipes Apps2sd ext partition
Wipe Battery Stats
Wipe rotate settings
Wipe .android secure : Wipes froyo native .android_secure on sdcard
Partition SD: Partition's sdcard for apps2sd (this formats card so all non backed-up data is lost)
SD:ext2 to ext3 : coverts apps2sd ext2 partition to ext3 (requires kernel support for ext3)
SD:ext3 to ext4 : same as above but ext3 to ext4 (requires kernel support for ext4)
Gui mounts to avoid typing in terminal to mount and cd into a dir to mount system, data, cache, sd-ext (if exists), sdcard
Fix apk uid mismatches
Move recovery log to SD
Key Test : Output keycodes for debugging recovery
Note this recovery and the one for Optimus One P500 have a service that instantly reboots out of recovery once you load it & I disabled it and thats why you get a E: "Bad Boot Message" on inital startup. Its completely fine.
Recovery Key mapping:
Up & down : vol-up and vol-down
Select : Menu
Backup : Back
