[LG Optimus 3D] Dexter_nlb:
RECOVERY IMAGE for SU760 ICS leak build for P920​

This is all based on wkpark's thread here but focused only for p920.

ClockWorkMod(6.0.1.5) and TWRP(2.2.2.1) images as flashable images, to be used after you installed WKPark's alternate bootloader using his root signature. then we get full recovery back working on top of ICS.

Download wkparks fastboot loader from here

and extract contents into a temp folder.

1a. follow his instructions on how to install device drivers then goto step 2 or

1b.

remove battery, attach usbcable between pc and mobile.

Install the omap4430 driver, when you see a device appearing in "devicemanager" named omap4430,

rightclick on it and install driver from the 7z download and look in folder usb_drv_windows for the device driver.

remember to be fast to rightclick as it wil disappear and re-appear often until driver is installed.

1c. pc will find and install driver at next mobile restart (which is some seconds after.

Download the modified x-loader.bin,u-boot.bin,boot.img from this post and extract content into the temp folder from step1 and put files into the files directory found there.

extract attached p920-2-twrp.zip to the files folder you find in your files directory in the temp folder

extract attached p920-3-cwm.zip to the files folder you find in your files directory in the temp folder

remove battery and disconnect usb cable from mobile.

enter the temp you extracted to at step1, and run start_fastboot and select "2" in the menu shown in the commandline console.

attach usb cable

wait for the "start_fastboot to show alot of details and show booting 2ndboot.

attach battery when the 2ndboot information shows

fastboot v0.5 should be shown with a grey LG logo on your mobile now. , if not, go back and follow steps again.

at this stage, it can happen that "fastboot" driver for "LG Cosmo" device is installing but cannot find a driver, so you need to update driver through device manager, and point to the drivers, where the omap4430 driver was located too and update it.

Now its time to flash to new files

run the 3 commands (one by one, do not try to copy/paste all 3 lines) shown just below as shown.

execute: fastboot flash x-loader files\x-loader.bin

execute: fastboot flash u-boot files\u-boot.bin

execute: fastboot flash boot files\boot.img

Lastly time to flash your recovery,

execute: fastboot flash recovery files\cwm.img

or

execute: fastboot flash recovery files\twrp.img

you

cannot

flash both images, as its not possible to have both recoveries installed.

You can always

boot into recovery by holding 3D-BUTTON + VOL-UP down while pressing power-button

to turn on mobile (without any cables attached to pc or power).

- If you do happen to get a bootloop it has been mentioned now, that it can happen if you copy/paster fastboot commands into the commandline shell.

these steps do NOT change anything of your system or data. it is only the bootloaders and boot.img/recovery.img which will change for the ICS build.

- both recoveries got USB mount storage issues, you will have to transfer files to sdcard or internal memory through windows.

- IMPORTANT: do not try and restore boot.img partition (before this install) from your ICS backups, it will cause the mobile not to boot.

and you will have to do the fastboot steps flashing this boot.img again. (it is caused by the signature is no longer a match)

wkpark - for his incredible work on getting us a custom uboot (still signed but a big help) - we await the unsigned boot :)

milaq - for the initial work on recoveries for our devices and cwm/twrp is used as base in these 2 images attached.

xbsall - the original release of ICS for p920/su760 edition.
