Is this phone more or less an international device? It shows as LG-F500K in the about menu. Would like to unlock and root.
AFAIK international version is H815
any F500 is korean version
not sure about the unlock, but for root, you can't use the current H815 method
Thanks. I realize I should have posted here initially. Guess I'll need to check procedures to determine if the device is unlocked already. I was told by the salesperson at olleh that the device was unlocked for both sim and bootloader.
Hi all,
On my phone the software say that my model is D852G but when I remove the back, its printed D850.
What does that mean? Is it possible to change to D850 on the software?

I wouldnt recommend it
In your case its probably using D850 hardware but software wise its been rebranded as a D852G. I can safely say if you try to flash a D850 firmware i might work but you will probably encounter alot of issues like described in here http://forum.xda-developers.com/lg-g3/help/us990-converted-to-ls990-calls-data-t3088944
Your senario is just like the LS990 and the US990 and how they have the same hardware but different software
I have a lg g4 h812 and its unlock and on T-mobile now. Since it looks like the h811 and h812 have same hardware could I flash h811 firmware onto my h812?
you could always try to flash the first revision of the 811 firmware that is below 10H, i've tried on mine and got me into HardBrick. Got repaired for free.

What version did you flash that caused the hardbrick?
From my understanding you should never cross flash models. Some g4 varients could be differ. But rule of thumb never do it unless confirmed to work
I've successfully flash a 815 & 818 into my 812, but we have to reflash the modem file of the 812 original firmware to be able to obtain network (wifi work but quite laggy).
The 81110H is the firmware that i've tried to install (Phone wont reboot after upgrade and show off like 9008 device) . i don't know if we could modify a kdz for being able to inject directly the modem of the 812 into 815 rom...
Yes you can
I've made this tutorial but you have to change some thinks to use in your variant
PS: you will get some problems with your modem (dont work)
If you found how to get working

I based my tutorial in another one

i've seen it before but flashing the 811 kdz give me a hardbrick. If i flash 810 then 811 that could work but cannot try it right now.

With the 812 we can't directly flash a 811, without causing a hardbrick. I was only wondering if i could flash a 810 successfully a 811 wont be a problem

Yes you can
But you have to flash first with lg flash tool 2014 (flash others kdz without problem)
And then with LG UP

Hello friend,
I am also thinking of flashing H815(international) rom onto my H812(Canadian) hardware. If you don't mind, could you please tell me how did the phone function with the H815 firmware?
Thank you very much. Your help is greatly appreciated.

you cannot use it for daily usage, the mobile network doesn't work and the phone will randomly reboot sometimes.

Ok thanks, I'm asking because I'm going on a long trip to UK and the Middle East for 6 or 7 months , and thought flashing the H815 firmware would make it compatible with those networks and therefore a free solution, rather than paying to have it unlocked.
Thanks

So by default, H812 has a locked bootloader. But despite this, the flashing of H815 firmware still worked?
If you read carefully all posts in most of the cited "how-to's" ...
If you read carefully all posts in most of the cited "how-to's" that have been linked in the responses you've gotten to date ... you will note that many problems are encountered, ranging anywhere from hard bricks down. Simply not worth the risk, IMO as there is not a high enough probability that you can get back to what you had originally that was working in the first place.
S.
So I opened my box today and realized the manual mentioned lg g4 h815t.... I have a h811
Looked up on website both are T-Mobile. What's the difference?
What phone do I really have?
Could I potentionally flash a h815 ROM?

The H815T is Not T-Mobile. The H815T are sold in Turkey and Hong Kong. It's mostly the same as the H815 variant.
If you flash an H815 firmware on your device if it's a H811 you'll permanently brick your device.

LG website states 815T is a T-Mobile phone.
It is possible the manual just has that model number listed and shipped with my 811 device.
How do I really check what version I have?
And why would they state 815T is a T-Mobile phone on their website?

I see no where on LGs website on the H815T page stating it's T-Mobile. If it does it's a glitch. It's 100% not a T-Mobile USA device.
Manuals may not matter as a G4 is a G4 operation wise.
What do you mean check which version you have? If it's a H811 then it's a T-Mobile device. T-Mobile only has 1 model for the G4.
Where did you buy your phone? If used/referb/second hand that might explain the manual mismatch.

Bought it through Rogers. Apparently rogers sells or sold h812
Box imei and serial number match to phone.
Must be manual...manual is a manual.
But why would Rogers be selling a T-Mobile phone.....when they have their own brand?
Anyway to check other than software?

Now that is what's odd. So you bought it through a actual Rogers store? And not a reseller that just happens to sell rogers stuff?
Rogers themselves I doubt would sell a T-Mobile device.

It was actual Rogers store. Not a reseller
Bought it unlocked. Sales rep said he could give me a deal on it so I took it
Glad I didn't get a 812 to be honest, read there are no custom ROMs?

If the H811 has an unlocked bootloader, will it still brick if one were flash the H815T firmware?

It’s not that it’s not been tried. It cannot be done. If it is you’ll 1. Result in a brick or 2. It won’t work and hope that you’ll be able to flash it back.
The modems in those phones are completely different. Along with the T-Mobile model having antirollback which makes it impossible

Ok well I have the H812 with antirollback value 0. once steadfasterx is fully complete his unofficial bootloader unlock, my plan is to unlock bootloader, install TWRP, then until custom roms for this variant comes out, I plan on flashing other carrier firmwares.... and it seems H815 has better updates, so probably going to flash that one...
Also, can you kindly tell me what you mean by "modem" in the phone? is it the thing that deals with frequency bands?
If it softbricks, I can always re-flash my stock firmware right? What are the chances of a hardbrick?

H812 won’t be as locked down as the H811 is. But flashing wrong model firmware is a no no. Flashing custom roms built on another firmware may not work correctly but won’t be as harmful as flashing stock firmware which will 99% won’t work and or will cause a hard brick.

Thanks very much.

Not saying you can, but that would be possible before flashing a stock kdz or tot.
Sorry no clue on Roms. Only keep up with stock and flashing to stock.

As long as the kdz your cross flashing is not a T-mobile kdz. You should be fine you will lose wifi calling and such.

Crossflashing does not change your phone model. Yes it will say that just remember what kdz your on?

Cool, thanks.
One last question I have is, can I update the software through the updater?
If not, when I do an "upgrade" option through LGUP, will it wipe my phone data, or will it be like any other update through the updater on the phone?
Lgup will wipe data. Going through the software update in the phone will keep data as long as you are on stock. If you are crossflashed to anther kdz software update in phone wont work. You need to manually update with lgup.
