DISCLAIMAR! Do it on your own Risk, I will not be responsible if you brick your device in anyway!

Its been a hell of a ride from newbie to first custom CM-12.1 ROM for my LG G3 Dual SIM phone, I really hate STOCK ROM! anyways I think kernel will work for Dual SIM [D857/8/8HK/9] variants and porting ROM to new device will not be much of an effort. You can check if the kernel works for you without flashing, just use "fastboot boot boot.img" if you has enable fastboot on G3 (by removing "Download Mode") otherwise take Backup [ALWAYS] and flash the zip to test if its boots on your Dual SIM variants. This ROM should work fine with Dual SIM models [D857/8/8HK/9] with few bugs as user's reported.

Yes both SIMS works! But in LG-D856 SIM 2 Slot is 2G only! What about D858HK?

Nothing just restore back for twrp, I think worst can be a boot loop. I played a lot with flashing myself with all sort of hit and trial to get the just right config

Twrp

---------- Post added at 09:00 AM ---------- Previous post was at 08:51 AM ----------

OK sadly there is a bug
Not able to get voice calls on second sim. Switch data to second sim, now I'm able to hear voice on sim2, but lost voice on sim1
Calls gets connected but can't hear and they can't hear me. Phone will ring and able to answer but no sound on earpiece nor speaker.

Strange thing I was able to get 4g on sim2:)

---------- Post added at 09:05 AM ---------- Previous post was at 09:00 AM ----------

Fyi:
In order to install, this what I did:
I was on 5.0.1 stock rooted
Wiped system/data/cache/davlik
Then flashed the ROM zip file,
no modem or kernel

Please advise if I need to do anything differently

@jeddahboy23 has confirmed, D856 ROM is working fine on his D858HK.

This ROM will work for D857/D858 as well, since my device specially mentioned it below battery compartment.
