To F400S F400K F400L (Korean version of G3) users - G3 Q&A, Help & Troubleshooting

Hi.
I am thinking to buy LG G3 Korean version but can anyone test about USSD/MMI Code? (For example *100# *118*8# *123#)
I use Prepaid Sim card so if USSD/MMI code does not work then I cannot top up(reload) or check balance or make a subscription...
The reason why I am asking this is because I have used LG G2 and Optimus LTE2 (Both Korean version) and For KT version, it did not work at all and for SKT version only half of the contents were displayed...
So can anyone check whether USSD/MMI code works?
F400L F400S F400K pls...

I have a F400K and it looks like the codes will work

help required for installing TWRP recovery.
Hi Guys
I have D855-HkG version with v10o kitkat version install, very uncommon version over lg g3. I want to move on lollipop but i didn't receive any OTA update. However, found new update after connecting with LG PC suite. Now i want to keep save my kitkat version too with modem settings, so that i can keep save my LTE carrier. but for that i need to install custom recovery.(TWRP). I have unrooted my phone quickly but not able to find TWRP version for D855 HKG version. Is HKG version and International 855 version same.? Any threats for installing TWRP / soft brick chances?
I will appreciate any help.
Looking forward for reply.
Regards

i know. i put me imei and its say that impossible to unlock. can you explain? h815 singapore this is what lg site say.
It's the SEA variant. And no, you can't change it to EUR and unlock it.
You can unlock it on the LG website: http://forum.xda-developers.com/g4/general/psa-official-lg-bootloader-unlock-815-t3233391
Thank you. After surfing in forum i understand all. BTW i have a Singapore device and i cant unlock it, lg site jumping an error. I see your topic about sea unlock and in last page you can see pic of this error. Maybe its need a time to arive to all devices?

How to find out which rom to flash on my D855

I had purchased a supposedly international unlocked LG g3 D855 32gb from eBay. Currently I am running kitkat 4.4.2 rooted rom which came pre-installed on the phone and it's rooted. There is no update center on my phone
Now I want to update it to lollipop or may be marshmallow but the problem is that I can't find which version of rom to flash as there are lots of D855 models in market there is European version, Korean version, Hong Kong version, Indian version. There is no clear indication on the box or on the phone abt the version is there any sure shot way of knowing what rom should I flash as I can't take risk of hard / soft bricking the phone. I am attaching screen shot of software version.
Please help

Hi
Download the app LGPhone From from play store, run it and one of the entries under serial no. will give a series of letters which denote area and carrier. E.g AGBRVK which is Virgin UK. Hope this helps.

Thanks for the reply
Downloaded "LG phone from" and "LG phone info" and it says original : FAIL
what does it mean
Sent from my Lenovo K50a40 using Tapatalk
Beneath the battery it's written MADE IN KOREA.
I m not really sure.. If its true or not
Sent from my Lenovo K50a40 using Tapatalk
If it is an original LG D855 the first entry should read OK, and then should list serial numbers and IME. Possibly your phone is a fake. I don't know as I have never seen one.

Korean unbranded android pie firmware

Is there such a firmware? Just got lg up+ carrier firmware with android pie and I was wondering if I can flash a clean unbranded firmware. Thx.

As long as it’s same region just open/unbranded all should be good..
But you won’t or may not get anymore OTA updates.
Forget this clean android pie korean firmware. I can confirm that for dual sim lg g7+ the network does not work - no calls, no data. IDK if it works for single sim, but reverting to another firmware brings back the network.
LG is still testing the PIE Beta for European LG G7 ThinQ G710EM - LMG710EM-V18b-EUR-XX-MAR-xx-2019

Yes had the same issue, so for now I'm sticking to Korean bloatware. I'm looking forward for the Indian version for my EAW
