1) Pacman kernel won't work on stock.
2) This kernel is for p760 not p768.
3) Unlocked bootloarder?
4) Just use kdz offline or online method and it should be fine.

0.- Im not responsable for any damage to your device i tested this only in my L5 from telcel Mexico wish had E612F originaly.
1.- Root your phone as it says on this posthttp://forum.xda-developers.com/showthread.php?t=2098550.
2.- When unlocking Bootloader use file for E610 instead of E612 and proceed as it says in the first posthttp://forum.xda-developers.com/showthread.php?t=2163698.
3.- Install clockwork recovery as it says in the post same as the one above.
4.- Install Custom Rom ( i used CM 10 from herehttp://forum.xda-developers.com/showthread.php?t=2184644 and it works like charm.! so far so Good and not even a single reboot).
5.- Boooomm!! Unlocked bootloader, custom recovery and custom rom.!

You can't flash any custom ROM on your P769 unless your bootloader is unlocked. Unlocking the bootloader on these L9's is almost impossible... On the newer versions of the L9, LG encrypted the bootloader. So unless someone figures out a new method to bypass the encrypted bootloader your stuck with it being locked and not being able to flash any custom rom.
There are a few ROMs for the P769 that work with a locked bootloader thought and would be your only option for a ROM other than 100% stock.
I use the Kumakan v3 themed ROM on my L9. There's another one, UltraRom which is based off of the kumankan ROM and a CM9 ROM, all are for 769's with locked bootloaders.
To install them, your L9 needs to be rooted, have BusyBox installed and you use the L9 recovery installer to flash cwm recovery.

If you already have CWM installed, then you're all set to install the custom ROM. Just make sure to run the Nandroid backup from CWM before the upgrade (better safe than sorry).

It means you have replaced the recovery to one that allows you to upgrade your ROM among other things (CWM that is).
Regarding custom ROMs - that's the big question: There are nearly no custom ROMs for this device, or rather to the L7 II series. If you browse the Android development section, you'll find some custom ROMs, but they are all based on the current 4.1.2 one. There's also an MIUI ROM for your device, about which you can read at the end of this thread. According to other threads here, LG has announced it would upgrade the L7 II series to KitKat somewhere round August (which should be any time now), so I guess the best thing to do would be to wait for it (as I do).

Actually, all that's needed is modem.img from the KDZ for the WiFi to work. Also normal flash should do it too.
Sent from my D620r [Stock 4.4.2 , -V- Kernel]
:good::good:
it's ok
Upload the screen shots.
Can I flash this with twrp recovery over stock kk?
D620r lolipop
When flashed via TWRP it works wifi, but not GSM. When flashed via KDZ, everything works.
Boot loop
I have a d620 that came with a v10e firmware. Two nights ago my phone updated to the 5.0.2 and I got stucked on the lg logo. Fortunately I've managed to flash it back using the stock rom. I really want to update to lollipop and I was wondering if any of you guys know how to get around the bootloop problem.

D618 V20b lollipop BUG on COC
is there any bug on COC graphic failures on war logs and etc.? on clash of clans?
im using the stock-rom lollipop - CIS version and the bug on the COC game.
you have Screen wake up notifications with Glimpse Notifications from google play, for all lg g2 mini. perfect.
I've flashed the zip on my d620r, everything works great. There are no bugs, battery life is very good compared with KitKat 4.4.2, and smoother overall. Great job!
Upgrade from V10g to V20a keeping data
First of all, thanks to all putting effort into this development.
I own a D620r with software V10g and KitKat 4.4.2, unlocked bootloader and TWRP. I used towelroot to root it. Everything runs fine so far.
I got a notification for the official OTA update to V20a and downloaded it to the device. I tried to apply it but were stuck in a recovery loop. I learned that official OTA updates need stock recovery and I cannot apply them having TWRP installed. I applied this fix to escape from recovery loop. The device is alive again, but the LG updater app asks to apply the downloaded update once a day.
Now I found this thread. The phone is my main device and contains lots of apps and settings. I want to keep the data if possible.
A) Do I have to expect trouble when I flash the V20a from this thread without wiping the data partition?
B.1) Or would the following procedure be an alternative:
Flash stock recovery (I made a backup using Rashr)
Revert bootloader to original locked aboot
Apply OTA update
Root
Replace bootloader with the unlocked one
Flash TWRP
B.2) I read that towelroot is based on a security vulnerability of the linux kernel that is fixed with Lollipop . If that is true, can someone give a hint how to root on Lollipop?
C) Can I choose between V20c/D620 and V20a/D620r or do they belong to different devices and are incompatible?
Thanks for your time reading this post.
Thanks
Thank you for the Rom and the instructions. It works great, there are no functions that are not working.
It also solves the bug for the smartwatches that caused battery drains on Kitkat.
when a version with xposed???

Never, because this is the stock rom in a flashable .zip for custom recovery.
And xposed for android 5 ist still alpha and doesn't work correct on our phone.
If you want to try xposed you can just install it.
Read the xposed thread for that.
Please don't ask any further questions about xposed here, this thread is only about zip flashable stock rom.
Thank you.
Installing this ROM
This post was a mistake. Question is below this.
I just flashed this ROM and a problem appeared
Every time I boot my phone up I get this message.
WARNING!
Current version is not available for user. Can't find matched cust for NT-code mcc/mnc[29403],subset[FF]
What does it mean?
EDIT:
Also one more question, can I update my phone OTA in case there is a new software?

[Q] LG L9 II CWM problem ??

Hi everyone, I have a problem with my Lg L9 II, it's the the stock rom but updated on 4.4.2 (KitKat).I have some bugs on my phone and it's a bit slower.I want to the install my original rom 4.1.2, I dowloaded him from your forum but when I transfer on SD Card and open CWM with the button volume up and power key I get the block ( I take picture and she is in attachment). I don't have a root. Can anyone explain me how to fix that, that I can install my original rom with CWM or TWRP. I hope so that You can help me, and sorry if the that thread is duplicate, I'm new here and don't know how it's work. Thanx in advice.
Kind Regards
did you had CWM installed!?
if you want "original" ROM (from LG), install the 4.4.2_V20g version via KDZ install (20g is the best version in my experience).
if you want cwm or twrp to experiment custom roms.... a good start: http://forum.xda-developers.com/showthread.php?t=2730501

You need to flash the respective V10x kdz(according to your region). V20 is KitKat. V10 is JellyBean.
