No, ROMs are device specific. You have to port it and add it to the list. I could attempt a port of this, I ported Firefox os to kindle fire HD, its hardware is very similar, and as long as there's a cm device tree that is ICS based or higher I should be able to attempt a build. I only haven't tried yet since my bootloader is yet to be unlocked, but I could attempt a build this weekend if you want, I just need a cm device tree.

OK cool, can't wait to see how this works, its funny you mention it after the fact because a few months ago running Firefox is would have been a complete pain because sgx GPU's were having issues, I was around at the time they fixed it working on kfhd builds. Can't wait to attempt a build on this and see how it goes. Only downside is I can't personally test out the ROM. That being said i can already think of a few issues that might present themselves since the hardware is similar but only time will tell...

Hi,
sorry my english is poor, do you have now any information that you need to build a FireFox OS Image (for LG P760)?
Or do you need anything else ?
thanks

I still need to find the device tree, but I'm going to bed I have to get up for work tomorrow and its late. I'll look into it this weekend.

may be the GIT Repo can help you

Thanks, I was hoping for a cm 10.2 dev tree but I can work with cm 11, their 4.3 builds were more stable than my current 4.4 builds on kfhd, though my 4.4 builds have a ton more bugs fixed from upstream. Thanks for that I will take a look at it this weekend.

ok thanks, thats a good part of it i think, i will have to see about putting together a manifest using that repo plus maybe a few others, last time i did this it was with a device that wasnt official at the time so i had a manifest generated for the process already that made my life easier, so i will have to do some research this time to figure out what repos i need, i can guess that one and definately the proprietary blobs. Will try to get this done sometime soon, ran out of time this weekend because i was also doing something on my domain controller to update some deployment images and the freaking power inverter for the lcd screen died...

a small update before i head to work, i managed to get it to start the compilation process now, so now comes the tedious debugging process, already hit one error about selinux attribs that needs to be set correctly so there arent duplicates, those are easy enough to fix, just thought you might want an update.

if anybody is still curious how this is going, i'm tryin got fix an issue involving the kernel not compiling, finally decided to go with using a prebuilt but iunfortunately having a hard time figuring out why defining TARGET_PREBUILT_KERNEL isnt working...

Found the Firefox OS trining manual (sort of)

Nt really my field of expertise, but I read the post and found something I thought might be helpful. This was a link posted by (Duckbill, I think):
http://csmg.lgmobile.com:9002/gdmsp...1&ret=1&curPage=2&searchtype=&keyword=&arg01=
It is a link to the LG South Korea portal of some kind entitled: 2013-11-04 FireFox OS Training Material. It is presented as a .zip file but when extracted with 7z, it only produces this:
[autorun]
open=LGMain.exe
icon=LGMain.exe,0
The file is larger than 5MB so I'm sure this is simply more LG encryption, although I don't really understand the implications of the instructions. On the remote chance that this is helpful, let me know how it helped.

I got a successful build, not sure if it will work but it built successfully. If you wanna test it post back and i''ll post the link soon, still have to upload it.

*** USE AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF THIS SOFTWARE OR SOMETHING ELSE SUDDENLY FRIES YOUR DEVICE. ***
ok this is just a alpha build so no guarentees it will even boot and since i have the p769 with a locked bootloader i can't really test the build. Again this is for the p760 and i would like to mention if it doesnt work i wouldn tbe surprised if you get stuck at the bootloader logo while the os is actually trying to boot, if this happens i blame the hwc module, so if it does happen i believe you should have superuser access at a adb shell and you can simply run
Code:
adb shell mount -o rw,remount /system
adb shell rm /system/vendor/lib/hw/hwcomposer.p760.so
adb shell rm /system/vendor/lib/hw/hwcomposer.omap4.so
adb reboot
that might fix a not booting issue. This is a barebones build, until i know i have a build that can sucessfully build i dont bother tsing bluetooth and rild and such. I can say that since i didnt make the modifications i did last time that i'm assuming bluetooth is probably not enabled right now.
anyways i will make this a thread in the dev section when its out of testing. Here's a link to the first alpha build if you are willing to try it: http://d-h.st/5Kq

anybody going to test this? I let it sit for a few days but i was hoping to have some testers by now. Can't really debug it myself without having a actual device thats unlockable. Theoretically i might be able to run this with a 2nd init exploit, never tried setting one up on a b2g os though.
