Does not work with t-mobile! Sorry.
Hello!
Good news for everybody! The new LG-UP v 1.15.06 not only allows us to install Pie, but also Cross Flash between devices.
Example: I live in Europe - Romania and I wanted my language for my LG G7+ EAW. Unfortunatetly this model is for Hong Kong and does not support most of european languages. No problem with this new LGUP. I just crossflashed my LG G7+ 6Gb Ram, dual sim to LMG710 EM. Maybe I can unlock bootloader with a little help.
I also flashed 2 diffrent LG G710N korean firmwares. All working fine.
The only problem was with the Korean open firmware, not supporting sim network, but I reverted back and it worked.

Easy commands for this new LGUP v1.15.06
If using powershell from win10:

1. Install USB drivers and put G7 in download mode
2 Open powershell from C:\Program Files (x86)\LG Electronics\LGUP (shift + right mouse) and type cmd and hit enter.
3. Type this command: lgup_cmd.exe comX "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "(path to your kdz firmware)"
Example: (if your phone is under com5 and your kdz is located in D:\ and has this name G710NO20c.kdz)
lgup_cmd.exe com5 "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "D:\G710NO20c.kdz"

thx for you sharing.:)
BTW flash 710em can't to unlock bootloader when you was 710eaw
Since the LGEurope will check u IMEI country when u get unlock.in
Yes, but maybe in the future we can get temp root and change imei to european one and unlock with existing unlocked devices codes. Who knows?

dual sim on the G710N (korean version)

Hi to all,

I own a G7+ (Korean version G710N) but the dual sim service does not work (since in Korean is kind of impossible and incomprehensible to have more than a sim card.
I'd like to install the Pie for the G710EMW (dual sim).
Have you ever tried to install different firmware on your model? Have you ever get any issue? (sim not working, bootloop, etc...).
Moreover, in the LGE developer webpage (developer.lge.com/resource/mobile/RetrieveBootloader.dev), seems like is not possible to unlock the bootloader of the korean model (I also tried by adb commands but I didn't success!).

Hope to read back from you,
Thanks in advance,
Benf

I was flash G710NO20f_00_OPEN_KR_OP_0308.kdz , my 710EAW ask insert USim and no service with no IMEI but clean firmware. Again with G710N20f_00_LGU_KR_OP_0308.kdz have 1sim slot 1 to call and 2sim received.
Have any way to flash G710NO20f_00_OPEN_KR_OP_0308.kdz with G710EAW10f_00_OPEN_HK_DS_OP_1126.kdz modem partition, i'm think this way to have Korean Pie for dual sim.

Now, i'm using G710EM10s_00_OPEN_EU_OP_0219.kdz DEC region. Dual sim and everything are ok, waiting for the next of LMG710EM-V18b-EUR-XX-MAR-xx-2019 (not release). But my G7EAW is still lost S/N after corss-flash to India 10t.
