You can flash HKG EAW variant for dual SIM & for some network VoLTE. Everything works well in HKG kdz. :fingers-crossed:
I wasn't clear (I apologize for my bad English) ... I wanted to ask what happens if I install the OPEN KOREA ROM on the LMG710EAW model? Do I lose a sim or just the phone does not work? At least one sim, would it work?
Thanks..

EAW is dual sim GSM variant, Korean Phone is single sim CDMA variant. Its practically not possible to work. So no sim works with that unless it's CDMA.:fingers-crossed:

Hello. Can I install the European version on the Brazilian model? LM-G710 EMW. Dual Yes. Thank you.

I found this version: G710EMW20a_00_OPEN_HK_DS_OP_0621.kdz
Compatible?

Hai. As I have seen many questions on various platforms about which and/or how to upgrade to pie on TIM region LM G710EM, lemme say my life story.

I managed to pass the bug that causes the firmware upgrade being stuck at 0% in the bootloader screen.

I have succeeded to install open eu20b kdz after a week of trying :D for anyone as stuck as I was, maybe this could help.

After a clean reinstall of all the drivers (i used the lg support mobile tool for qualcomm driver) and latest LGUP for store (works wirh dev ver. asw), i still wasn't able to upgrade.

After TAKING OUT THE SIM and rebooting from the firmware upgrade screen, it finally worked.

Region TIM LM G710EM, purchased in June of 2019 in the Czech Republic.

Sorry for an eventual repost, but maybe it'll be of use to some1.

Hi , need a quick help.
I have an Indian Device, I followed Step 1 and flashed the European KDZ * Before* unlocking the bootloader. Now when I'm trying to register and unlock the device through official method, lg site says my device is now supported. Model : LM- G710EMW .

Any help will be hugely appreciated !

Only lg g7 EU variant can have unlocked bootloader. Bootloader of any other variant cannot be unlocked by official method. :fingers-crossed:

Probably because EU pie does not support the same bands. Not sure exactly why but if you already have the Korean model it's better for you to use Korean pie because it updates faster

Thank you for this guide :)
Does it have a special purpose to flash this via lgup_cmd instead of through LGup GUI version, or it doesn't matter?

//Edit: Thanks for clarification.
