Sorry for late reply, I didnt install any new build, i was on stock jb build with V20c baseband, thats it,
n u need to be on latest stock jb build for unlocking bootloader,
above method works on almost any baseband
there are lots of different methods for unlocking bl for l9,
simple one is, (on device)
if u r rooted,
then install teminal emulater
open that
type "sudo"
hit enter
then type " adb reboot oem-unlock "
device will boot into bootloader mode,
press volume up, done
then follow rest of process, as above.......

Updated P765 -v20C(Indian Version) to CM11 -Kang by Dhiru
Hi All,
First of all Thank you Droideking for the detailed guide for a noob like me. :good::good:
I have updated my L9 p765 Indian version with baseband version 20c (latest JB Update India) to CM11. I have used the ROM - UnOfficial CyanogenMod 11 [KANG] 11 by dhiru1602. The experience is awesome. The GUI is liquid smooth no lags unlike the stock ROM.:victory:
About the guide I would like to confirm that it worked absolutely fine for my Indian Version p765 with v20c baseband. There were no restarts encountered in fastboot mode. Only thing which happened was that when i was running adb command in the command prompt i got the error on command prompt saying adb is outdated please update. The error was gone when i ran the command prompt with run as admin option in windows. Also i used RomManager instead of GooManager as it was not available on playstore.
One more observation - Droideking, in the guide you have mentioned that install gapps after installing ROM and restarting the phone after completing setup. I followed the same but then i realised that RomManager was done as i did a reset and wiped the cache and done a reset. So had to download the RomManager apk on the sdcard and install to boot into recovery to install the Gapps. So i guess its better to install the Gapps soon after you have installed the rom in the recovery before restart.
Here are some of the screenshots of my p765..

God saves you buddy, this problem occurs due to wrong recovery, recovery stops itself from installing rom, n saves you from bricking device,
install latest recovery, 6.0.4.8 or twrp latest release, below is the link
recommend twrp
