Before you read this theard:
There isn't any rom which you can install.
This Development Thread is for users who have any idea, something to share.

As we know our L9 has locked bootloader. We can't flash boot.img and recovery.img, but we can load custom ramdisk and recovery through 2nd-init.
What is 2nd-init?: Read there: http://cvpcs.org/blog/2011-06-14/2nd-init._what_it_is_and_how_it_works
My CWM Recovery for L9 is also loaded through 2nd-init, so we have ready 2nd-init scripts. Where recovery and custom ramdisk will be storied:
boot.tar (custom ramdisk): /system/bootstrap/boot.tar
recovery.tar (custom recovery): /system/bootstrap/recovery.tar
So, we have 2nd-init script, we can start porting rom to our device (I have P760 variant). We have to port rom from Prada 3.0 and Atrix 2 (very similar devices) or compile from sources. For now 1st option is better because we haven't got any sources expect 10a rom.
At the end I attach full 2nd-init script. You can test it on stock rom, it works. Only need to edit ramdisk and port some files to get working CM9/10. Link to ramdisk is in second post. In the most part it is playing with the files and ramdisk (like editing the lg prada, 4x was edited stock ramdisk), because we can not run custom kernels. There are many specific files, which ramdisk, kernel checks md5 checksum of this files (drm files).
IMPORTANT INFORMATIONS ARE ALSO IN POST BELLOW (2nd post, links to important files).
This is the end for now. Theard will be updated.
What can you do:
Post something useful for us
Have an idea, write there
Links to useful websites/theards
Share some info about porting roms to L9
Notes about the idea, porting roms, very important information
Please don't:
Ask for ETA's & Troll
Edit: Now. Cyanogenmod 9 is working. If you want to port roms use this rom as base. Ramdisk is storied in /system/bootstrap/boot.tar
For now I don't neeed tester, It don't work for now. I and persons who help me are working, but it isn't easy as porting with unlocked bootloader.
For devs. Some informations and links. I add some important links. Some of them are from Optimus 4X. I added it, because In 4X CM10 ramdisk is fixed drm conflict (everything I will write in this post).
LG Prada Cyanogemod 9 (uses 2nd-init, stock LG kernel, easiest way to port): http://goo.im/devs/milaq/p940/cm9/cm-9-20121126-NIGHTLY-p940.zip
LG Optimus 4X CM10 (there is fixed booting, drm conflict). Important files in this rom: /system/bin/netd /system/bootmenu/boot.tar (also I upload it without rom), /system/drm, system/drm2, /system/lgdrm.tar: http://d-h.st/ivJ
10b (branded 10a) P760 system and boot (ramdisk) dump: http://www.mediafire.com/?9b4oywl94j0bp
Optimus 4X Stock boot (ramdisk): http://www.mediafire.com/?k48h27ln4xnygrh
Optimus 4X CM10 ramdisk (you can compare with 4X Stock ramdisk, see what's changet, try to do this on L9, also included in 4X rom /system/bootmenu/boot.tar): http://www.mediafire.com/?fia0d72cs93cy71
Stock P760 ramdisk with ro.secure=0 edited to work with 2nd-init (bootable, working, to boot install cwm recovery and copy boot.tar to /system/bootstrap, it's base to port cm9/cm10). Only one bug is soft button light:http://www.mediafire.com/?ra5itp818uijpk3
CM 10 for Atrix 2 (similar device to L9): http://forum.xda-developers.com/showthread.php?t=1869692
Important theards/posts:
Similar devices to L9:
LG Prada 3.0 (The same platform, manufacturer, different screen resolution, similar ramdisk, also similar some files specific to platform, phone model)
Atrix 2 (the same resolution, platform, other manufacturer)
hi,i have a P760,if you need testers count with me.
have you recovery installed and i know how to flash kdz and everything else.(install zip and create backup).sorry for my google translate..

I have P765, fit for all your requirements, but don't have much free time. In any case, I will try to help if I can.
I can test the rom on a P760
Hallo guys, finally we have our sub forum, for me to begin will be also good to have one clean and deodexed stock rom with some advance, like script for kernel OK and........
Also agree to port cynogen 9 and other rom:thumbup:

count me in... P760... had a lot of android based devices. so i know to flash via recovery, also flashed P760 several times via kdz..
can test for the p769. I'm well versed in cwm flashing and have reflashed this phone using kdz several times.
P-765 user
Let me try it
i will test as well, got an lg l9 P760 thats the reason we are here. to support and try :highfive: hope it works and to go forward even more with CM 9,10, 10,1 ....
I can also help test with p760 , can do all that you ask and have alot experience in device modding/testing
Hi man! Im a developer for three lg phones and have p760! Do you know how compile cmX for phone that have locked bootloader?
Inviato dal mio LG-P760 con Tapatalk 2
P769 here.... happy flashing etc.
Sorry saw the post very late. I am here for...
P765 Indian (Asian) variant.
Excellent write up on 2nd-init at http://cvpcs.org/blog/2011-06-14/2nd-init._what_it_is_and_how_it_works
Thanks it explained many things and hijacking booting sequences.
I know its really early, but do you think its possible to have a touch led notification feature built into a rom? Thats the only thing missing from this phone I dont like. I miss having a blinking light telling me if I missed a call or message.
I know theres an app on the store but from my using it, its pretty buggy and doesnt always work. And it seems to eat up the battery too.
Would be difficult to compile the original KDZ 10E with root after install?

Not only that app but this feature itself is battery consuming. Tried this on O2x and removed after noticing battery drain.

ICS Source code for all L9 variants (except 765) are released. Should it be a problem for devs to compile rooted KDZ from source? Just curious to know this from devs.
One more thing, now as CWM by Artas185x is fully working, is it possible for sharing restorable zips with rooted roms? Again just curious to know.
well as of now i have set up a petition for lg to unlock the bootloader of all L9 Variants maybe if we get enough signatures they will do as they are doing with the 4X and the optimus G in my signature below hopefully they get a hint

I guess its because the cpu gets woken up each time the leds go on? Is there a way to toggle a low brightness blinking or pulse when a notification is received that will shut off again once the screen is turned back on? I wouldnt think one or both of the leds blinking at low brightness by themselves would take up too much battery power?
I've just signed the petition and i'm ready to test with P760
hi friends xda) needs your help! I decided to
port the unofficial cyanogenmod 10.1 for a
single device! but when you try porting
eventually received a non working rom ((I
hope you can help me?)

You will need the kernel source code from the OEM of the device before you can get very far.

There is no FAQ on this as most of the OEM of the clones never release the source code to their kernels as the device is not an official android device.
clear, thanks for the info and the last
question: is it possible to install another rom
device similar characteristics of my device?
performance in the first post of this topic
Hello everyone
My plan was to get dual boot on my z5c using "multirom": the first would be the stock rom (Nougat), the other one was the aosp rom built by Sony itself, in order to unlock some feature like raw capture and long exposures, that seems possible with aosp based roms and "Freedcam" (look for defcomg developer).
Do you think it's possible to mix these two roms with multirom?
What I'm supposed to do is
-Backup the TA partition
-Unlock the bootloader
-Root with dirtycow exploit (does it work with Nougat, doesn't it? Is there a way to get multirom without unlocking the bootloader?)
-Install multirom
-Flash the roms
It this right? Am I missing something, or is there something I must particularly care about? I wouldn't want to brick my phone, and I'm not too experienced, but I think I can follow instructions. Thank for your attention
Got it to work?
I know, this is an old thread, ok.
But ... did you get it to work?
Is kernel development for our beloved v10 as simple as building any other kernel? I just want a quick answer so i can try to learn to build a kernel just to do so in my free time and can anyone give suggestions and or links to what would be needed in order to get started.
Things I know that are required:
-linux (most likely will use FWUL, so if i brick i should be able to restore)
-toolchain for kernel compilation
-phone
-usb cable
Things to figure out:
-sources
-how to make a flashable zip when done(if i ever get to complete such a task)
-help from anyone with knowledge to share is welcome
p.s. does this thread belong here or general?
I am completely new to Android Engineering and want to learn it. Till now, I have tried building aosp oreo from repo. It is built successfully but I don't know about the use of all the folders that are downloaded by the repo. What is the use or importance of each folder in repo? Where can I learn more about this?
I have also modified my stock firmware (only removed some bloatware apps) and rebuilt the firmware. I haven't installed it yet. I used android kitchen which helped me with signing the zip but I am afraid the signature might be for testing and not the official vendor signature. I have phone with unlcoked bootloader but it's still on stock recovery. According to my knowledge, unlocking bootloader helps us to flash unofficial files but people at XDA say that we should also have custom recovery to flash custom ROMs. Should I flash the modified ROM built by me in device with stock ROM and unlocked bootloader?
My device doesn't have official TWRP support. How can I port recovery or build it from scratch for my phone?
Also, I have only modified stock ROM and need to learn porting ROMs like porting MIUI for my device. How can we port ROMs?
Sorry for asking all these at once but I tried getting answer one after another which confused me a lot. I am a noob in this field.
I read XDA thread of TWRP developer which included a guide on how to build TWRP for any device. But as the author said, that post wasn't for noobs. Maybe I need to learn a lot before I reach that level of understanding. But I don't know what to learn and from where. Please help..
And one last thing - What is a device tree? Or vendor tree? I saw these words many times when I was trying to understand the above things. But I still don't know what these are and Google doesn't help. Thank you everyone..
