make sure busybox is installed correctly and all commands are available in /system/xbin (normally part of rooting installation)
Download the attached zip to this post
extract the apk from inside the downloaded zip file.
install the LG-Optimus-4XHD-Recovery apk on your mobile
after installation reboot mobile once (if you do not, the app might fail installing recovery)
start the LG 4X Recovery app
press - Install recovery - grant superuser access when prompted
wait for success OK, if it fails, something is wrong or SU is not properly installed or denied su access. you should set permissions to granted for this app
after successfull installation, you can press boot recovery and boot into the clockworkmod recovery and make your backups or install custom roms
when you do a backup, remember that CWM v126.96.36.199 got a bug, so you need to specifically chose backup to external sdcard for now.
- uses latest boot base from v10f (OPEN edition), but not much changed
-Found issue with unmount of /system and other filesystems during start of clockworkMod, making it hard to restore backup.
all filesystems are now properly unmounted and services stopped which could use it.
- for adb users, unplug usb cable once, to re-activate adb connection when cwm starts.
current issues backup to internal sdcard location is not working , use backup to EXTERNAL sdcard (problem is the link in / which point to /mnt/sdcard)
(FIXED in v1.1) factory reset/restore backup - if you restore a backup or factory reset, it will also wipe your internal storage/sdcard location. as LG have chosen to use part of internal store on same partition.
so where possible, always copy your internal storage files to a safe location
(Koush removed this option in v188.8.131.52)external sdcard - mount usb - currently shares only external sdcard storage to pc.
It is to assume, that anything restored from a backup, will include any 4X clockwork recovery, as this is located on your system partition.
so its always good to install the newest apk, after a restore of your backup.

information on the technical solution used
The bootstrap solution used to run ClockWorkMod is based on the 2nd-init function , which has been around for some time now.
Additional functions are used here, based on services started and building small changes into the unsecure ramdisk, so we get the full functionality of our device.
For those technical users, wanting to use my work, just remember to mention where you got it, and i have no problems with others using scripts.
It's also important when booted into recovery, that you restart adb (adb usb) to get full root access.
as this recovery is not started from a clean bootup, some cleanup jobs are required for those, that MIGHT do a custom rom.
i have seen with my works in progress, that jellybean and htc roms use different services and those needs to be included in the bootmeny/bootrecovery script to stop and cleanup what ever service started originally. so when/if someone makes a different rom, remember to update the bootmenu scripts, which i guess you know how to change if you do customroms.
i am almost ready with the complete package for recovery install (NO root install or similar)
requirements will be that you got o4x root'd to run this installer properly.
Since we got no key detect function in bootup(missing in kernel) available or binary app to extract a keypress, this app will need to run to activate recovery at next boot. thats the solution for now.
