[LG Optimus L9 P760, P765, P768, P769] kuma82:
Alright we have a CM9 for locked bootloader but we don't have CM10 and the people that want to help don't have a clue about where to begin.

I really didn't want to make a new thread but so much stuff is scattered in several places on this subject, and I don't feel like jacking peoples thread to answer "how to stuff".

artas182x already ported a 2nd-init (rom and recovery) for L9, so we just have to figure out the right settings to make CM10 boot.

Please read this thread http://xdaforums.com/showthread.php?p=36706378

The only CM10 I have so far is from markolino631 http://xdaforums.com/showthread.php?t=2313036

One of the first things you will need to learn is how to make a boot.tar or recovery.tar for locked bootloader.

How to make a boot.tar or recovery.tar

Things you will need Linux OS or cygwin (for windows), osm0sis's mkbootimg (Android Kitchen has it all set and ready to go), and last but not least a brain ;)

okay you want to make a boot.tar, well we first need to get our hands on the boot.img. So I'll just use a stock boot.img for this example, but we really need CM10 boot.img.

I am using cygwin and Android Kitchen for this example.

First navigate to advance options (#0) select number #12 (in advanced options) and select option "a"(Extract kernel+ramdisk from boot.img/recovery.img in any folder).

Place the boot.img inside the new folder it specifies and hit enter. Afterwards you will have a "zImage" file and a "boot.img-ramdisk" folder.

Now exit the Kitchen (just press Ctrl+c) and navigate to the new folder

with cygwin

(shorten the folder name if you want, like I did in my example).

Kuma Family@KumaFamily-PC /home/Kuma/Kitchen
$ [B]cd bootimg_stock/boot.img-ramdisk/[/B]

Once in the "boot.img-ramdisk" folder we are all set to make the boot.tar

However, lets check the permission on all the files in that folder.

So type ls -ln and make a note of the permission for each file, without the proper permission it won't work for sure.

Now type tar cvf boot.tar ./* and a new boot.tar will be created in that folder.

$ tar cvf boot.tar ./*

Once you made your boot.tar (and made the changes you wanted) you can place the boot.tar in the system (/system/bootstrap/) with the correct permissions

chmod 755 /system/bootstrap/boot.tar

I already made a couple of recoveries and modified ram disk using this method.

For recovery type tar cvf recovery.tar ./*

I'll be posting some more stuff but i really have my hands full.
