Porting stock L-01F (Japanese G2) ROM to d800 (AT&T G2)

I would like to know if it's possible to port the stock ROM of Japanese variant of the LG G2 (L-01F) to an AT&T LG G2?
I travel a LOT to Tokyo and using my phone on AT&T will just cost me an arm and 50 legs when I'm half across the world.
I'm thinking if I just flash the stock ROM of the Docomo version that it'll work, swap out my AT&T SIM card for a Docomo SIM card - flash the ROM and be good on the go. And when I go back to the states I'll just restore the nandroid of my AT&T stock ROM and slip in my AT&T card.
What exactly does it take to port the ROM over? I'm hearing that just flashing the ROM and flashing the AT&T kernel would work just fine.
Thanks for the help!

Bump, I really hope I've posted this in the right section.

I'm not a developer or anything, but wouldn't you need to unlock your phone for this?

Yes my phone is unlocked but some off the apps that are exclusive to Docomo handsets are locked and some are tied to their ROM framework and such. I tried downloading certain apps to see if I can get them to work on the AT&T ROM but it's a no go :\

Who is your carrier? You might want to call them so you would know.

[Q] Can I flash Tmo Stock Image on AT&T Model?

Just ordered my wife a G2, it is unlocked however it is the AT&T variant and we are on Tmo. I have read that someone took a Tmo rom and made it possible to flash this to the AT&T model along with the KK baseband so that we can use Tmos wifi calling. However I would like to know if I can simply just flash a Tmo stock image and flash the KK baseband if this will work or am I looking into this all wrong?
This is where I read about the Tmo on AT&T rom:

Can anyone tell me if the ROM mentioned in the link above is this the latest ROM for the G2? Thank you in advance.
Side Question, if I want to flash Cyanogenmod and still want to retain the wifi calling can I flash the Tmo rom along with the aforementioned KK baseband?

THIS IS AN ABSOLUTE AND COMPLETE NO GO, FLASHING A FACTORY IMAGE FOR A DIFFERENT MODEL CAN HARD BRICK YOUR DEVICE, IN FACT I'D PRETTY MUCH GUARANTEE IT!!! GO INTO THE ATT DEVELOPMENT THREAD AND FIND SAID T MOBILE ROM FOR YOUR DEVICE, FLASH THAT IF YOU WANT TO. As an answer to the side question there is no way to retain wifi calling on cyanogenmod, especially on a non tmo device. Finally as for the baseband find out what baseband the respective ROMs need (the tmobile one for ATT G2s or the CM build you choose to use).

Will updating/flashing a new rom re-lock my unlocked LG G2 (F320s) ?

Hi all,
I recently bought a Korean version of LG G2 F320S from a friend of mine. I had to get it unlocked so that I can use it outside Korea.
It comes unrooted and is currently running Android KitKat 4.4.2. As I want to explore more, I want to manually update my phone to Lollipop and flash custom roms. But the problem is I am not sure if updating/flashing a complete new rom will make my phone become locked again. Moreover, is CloudyG2 3.3 compatible with my Korean G2 F320s?
Any input is appreciated. Thanks in advance.

Did you got it unlocked by the carrier or by any fix too-smart-not-to-pay-a-few-money method?
If you got it unlocked by paying don't think you'll get any errors or relocking. Already tried it with many other phones (htc, Samsung, sony) and never got any errors after paying.
That about compatibility of cloydyfa's Rom is a question I can't tell you for sure, search it in the Q&A thread

afaik, cloudy3.3 was first released for your variant... because korean variants got lp rom first (other variant releases followed few months later)...
to be sure, check the cloudy thread
