Hi guys! Obvious with an official cm10.1 by team cyanogen we have also a recovery and possibility to flash root!
And here is a simple guide to flash it!

Pre-required:
  • Jelly bean
  • Driver lg installed correctly

Download:
  • For Rom Toolkit tool 2.0: http://lgics.altervista.org/
  • For root: Download


    Rom toolkit 1.3 - Added Cwm recovery 6.0.3.1
    Rom toolkit 1.3.1 - Added option for download lg driver
    Rom toolkit 1.4 - Added option to flash recovery for kitkat
    Rom Toolkit 2.0 - New interface



    Remember for unlock bootloader you must wait about 1 hour with jelly bean and phone on! don't reboot it!

    Unlock bootloader and Flash recovery:
    • Connect phone to pc with debug mode and software lg on
    • Install Rom toolkit tool
    • Execute Rom toolkit
    • Press "Unlock bootloader" and your phone reboots into an LG mode and you must press vol up to unlock bootloader
    • Then press "Flash recovery" and program flash recovery - if phone reboot automatically the recovery is flashed, if no see if pc recognize phone when it is on fastboot mode
    • Hold vol up + home button and power button and release power button at vibration for boot into recovery!

    Install root:
    • Reboot to recovery
    • Flash supersu zip
    • reboot!

OH MY GOD! Its dangerous :eek:
(Vol+)(Home)and(Power)=Recovery Mode
(Vol-)(Home)and(Power)=HardReset?
If your one finger slips down carelessly just one centimeter down, and your phone is BLANK.
Be careful guys.
====================

wooohoooo!!! :highfive:
+1 ROOT WORKED PERFECT:good: Flawless.... CWM by Aremcee and Root by Marko. I knew it L9 will fly with unlocked bootloader. NOW I CAN SLEEP EARLY TONIGHT! Thanks a ton. Now I am on ROOTED P760V20B JellyBean Europe Open :D

Markolino, guess what? I had Superuser0.7CWM.zip (flashable zip) on my external sdcard which I used longtime back for O2X, but damn , I did not even think about it. Thats really a shame. :crying: lolz:laugh:

EDIT: Seems Busybox missing from both folders, Where should we install it "/system/bin/" or "/system/xbin/"???

you need to wait to let your computer detect and install drivers while your phone is in fastboot mode. if they dont install then you will have to google for universal fastboot drivers.

Windows is stupid, does not installs drivers (already installed) in pc. It tries to detect over internet for latest WDM drivers and drivers FAIL to load.

Always click this button while installing drivers and wait with patience.

Actual screen while installing drivers for ADB and FastBoot Mode. :D
