First of all, I have to officially thank user kalunlee for his help in this. He pulled the files from the chinese forums, and in there you have to either register or pay for the links. Without his help there would be no guide.
XDA is open for everyone, on those Chinese forums they keep their resources well hidden, but they don't bother thanking the people here on XDA for their work (rooting tools maybe?), and they even get credits for the tools taken from here! --rant over--

Let's start now. This guide is for all user of D857 or D858 wanting the Google Apps on their phones without messing around with rooting and custom recoveries, but want to keep the phone in a stock condition. Model D858HK is the only Dual Sim officially supporting the GApps, the goal of this guide is transforming a D857/D858 into an HK model.

Istructions:

Enable USB debugging on your device: menu > settings > developer options.
Install Stump Root and root the phone. Install SuperSU immediately after reboot and run it.
Install Build Prop Editor apk (I used Build Prop Editor from joeykrim, the other one didn't work), edit ro.product.model=LG-D857 to ro.product.model=LG-D858HK.
Install LG Driver.
Install LGFlashTool, overwrite the megalock.dll with the provided one.
Turn off phone, hold the volume up key and plug into the computer (DOWNLOAD MODE).
Let the LG driver install for your phone.
Go to device manager in Windows Control Panel, change LGE Mobile USB Serial Port to com41
Open LGFlashTool select the right TOT file and dll (use BOARD DL)
Go to Port settings set LIMO Port to COM101 tick port 1 only on the right (Basically first 3 items ticked)
Click Start
Remove the cable for 5 seconds and reconnect, the flash will start
Flash
Done
Now you have a D858HK instead of D857.

If you get a port error at the starting of the flash disconnect the phone, remove LG drivers, reinstall them again, change the port to com41, and without rebooting launch again the flashtool.

If you get a Windows error, remove any antivirus you have!!

If at the end of the flashing procedure the phone boots into the miniOS, then pull out the battery and enter into the recovery and do a factory reset. Reboot. When in miniOS again, press the power button and tap on normal boot!

For those of you needing to root, here is my guide, just follow it without installing the GApps, it's useless now!

Yes, after transforming the phone into a D858HK, you'll be able to install any OTA update that will be pushed to you. It's not like the G2, no more OTAs after this guide, you will have to manually install the update.

DO NOT INSTALL v10c on the D857, it's impossible to root at the moment. If you do, the only way to go is the downgrade. I will set up a new guide soon if I'll be able to do that on mine (learn the hard way ) Look for D857v10a TOT. Downgrade to v10a, root, then follow this guide to transform to a D858HK.

Will edit with more detailed instructions soon. STAY TUNED!


--------D858HK v10f--------

The question is: can we do this for all variants? Like vs985/D851 to D855

I just flashed mine, everything seems OK, just at the end LG Flash Tool showed "Waiting for reset 120 sec", phone restarted and setup screen showed up.

Then LG Flash Tool showed error message "download failed" and "USB port open fail", but phone works well. Any idea why this happened?

Don't try to flash other LG G3 to this version. It only works for D857 or D858 to D858HK. These are the dual sim version and all have the same hardware.

Not sure what happened to the links but you can try the links in the original post

http://forum.xda-developers.com/lg-g...t2882412/page3

You can ignore the fail message at the end, it happened to one of the phones that I flashed too.

That's not actually accurate. OTA on D858HK are IMEI based, so even the D857 (or mainland D858) is flashed into D858HK, it won't receive any OTA notification still,as your IMEI will be designated to D857.

I'm not exactly sure if there s any way to side load the OTA without root/flash Tot, I hope someone will find a way when new OTA files are available for this.

You're partially correct. OTAs are theoretically IMEI based, but it has to match the installed firmware and firmware keys of the device, in this case you'll have 858HK keys, thus 858HK OTA.
On the G2 I changed firmware successfully twice to change the region (thus enabling few needed LTE bands), and it got two OTAs for that region, not for the original one.
Time will tell BTW!

That's what happened with the G2. Couldn't get 4G in the UAE with Open EUR firmware. Switched to UAE firmware and got LTE!

Be careful, you can't flash a D855 firmware into a D857/858/859 phone! You'll brick it!!
