[ROM] [KK 4.4.4] OmniROM && MultiROM TWRP 2.8.0

[Adam77Root]

Hi everybody!

This is the development thread of OmniROM (based on Android 4.4.4 KitKat) for the LG Optimus 4X HD (p880). More information can be found here.

For general discussion and Q&A: head to this thread.

What doesn't work:

• QR/Barcode scanning and similar apps
• Maybe other things

Links:

• Rom: https://dl.omnirom.org/p880/ (For older homemade builds check http://d-h.st/users/Adam77Root?fld_id=26470)
• Google apps: http://forum.xda-developers.com/showthread.php?t=2397942

Installation method:

• Flash OmniROM.
• Flash Google apps.
• Do 'Wipe data/factory reset' in recovery.
• Reboot & enjoy.

Note: You need to have a KitKat-compatible recovery, CWM v6.0.4.4 or CWM v6.0.4.5 is reported to be working.

MultiROM TWRP 2.8.0 (recommended recovery):
Link: http://d-h.st/users/Adam77Root?fld_id=22980 (latest TWRP_multirom_p880_*date*.img)

Every custom modification to devices have risks. Flash this at your own risk!

Have fun and enjoy!

I don't really care about BT so if the lag bug can be fixed with a different kernel like Optimus Play then this could be a perfect ROM

The ROM is multilanguage?

Good evening everyone, I would just like to remind you all that OP has opened a discussion/Q&A thread in general section about this ROM so if you people have something to discuss or some questions try to post it in general section. It will be helpful for some other users who do not like to read around 1000 posts to get some knowledgeable information.
@Adam77Root correct me if I am wrong.

Have fun people.
