Hello everyone.
I've updated to marshmallow recently but i want to try rooting the phone.
I want to do this without unlocking the bootloader because I don't really know how much trouble LG will give me with warranty issues.
So I've found a couple of guides here and there about using LGUP to flash a KDZ file. For the H815 model there are many different versions with different country codes. Does that matter? I have a Dutch G4 but I see the Polish version being much more recent. What difference does that make? Or is it better to flash the Open version? They do not seem carrier branded.
Is it even possible to downgrade?
Thanks.

Hello. I you can see I'm new to the forums and I'm also new to my LG G4, which happens to be the Taiwanese variant of the H815. I love the phone so far, but I'm a bit bummed that the bootloader can't be unlocked on this model. So I have two questions about this.
If I were to flash the EU Open VDZ, could I unlock my bootloader then?
A lot of the settings are geared towards Chinese/Taiwanese markets. Is there a US H815 stock firmware, or should I use a European version? And what number is the US H815 firmware version so I can go ahead and download it.
Thanks in advance.
P.S. A U.S. firmware should fix most things for me, correct?
Each region/variant has different firmware numbers.
IE 10c TWN/SEA is the "same version" as 10E of Open EUR which is higher than which is the same as 10F of the 815T which is a higher version than 10G of some non open EUR phones...
You can install the Open EUR KDZ on the TWN version, but it will not enable to unlock your boot loader, the LG unlocked website checks IMEI and unique hardware ID to determine eligibility. You may be able to flash the US H815 but I'm not sure.

Thanks. I'm guessing there's really no point of flashing a new ROM then. Do you know the USA H815 firmware number?
I looked through the forums and am still confused on this version.
So only H815 Euro version can unlock the bootloader officially, while the H815 USA version can't.
But I've read some posts peopple flashing H815 USA version with custom roms?
How is that possible and I can't seem to use the right key words to find the relevant post.
Any help would be greatly appreciated, thx!
Hi, can anyone point me the proper root method (if any) for LG G4 H815 TWN version running v20c software version? I've tried searching through here and also google but until now I just couldn't find the relevant method.
Or can I just use the same method for the EU H815?
Thanks in advance and sorry for my ignorance.
Hello
I've just bought a LG G4 from Amazon UK marketplace.
It came with rom 20c-TWN-xx (Android Marshmallow)
I red many posts about root, unlock, downgrade, and each combination is nearly the same but not exactly the same as mine, and i'm afraid to stuck my phone.
In fact, i wonder if it is possible to replace this TWN release with http://storagecow.eu/Xda/LG G4/H815/Marshmallow 6.0/Europe H81520C_00_1218.kdz using LGUP then obtain an unlocked bootloader from http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS
If not, is it possible to directly downgrade the 20c-TWN-xx with Lollipop http://storagecow.eu/Xda/LG G4/H815/Europe OPEN 0H81510D.kdz then root the phone with any method ?
Thanks for your help
I'm in same boots as you. I am also wondering if there is ANY way of getting this baby rooted.
Please make a thread on how to root H815 twn please anyone
Sent from my LG-H815 using XDA-Developers mobile app
Please anybody answer can TWN version of G4 be downgraded to european version of lollipop ?????/
Hello guys, I bought a LG G4. The seller today said that they have sent a H818P Dual SIM version. I already have an G4 H815 European Version and I wanted exactly the same one to easily unlock bootloader, root new ROM flash etc. after warranty period.
Should I send it back or should I accept it? What do you suggest to me? Will it be easy to find custom ROMs for H818P in the future (2 years later).
Also, is there any significant differences between them especially for my country Turkey? I have read some posts about rooting H818P with H815 ROMs. Are they easy to cope with? Or is it better to send it back.
Thank you beforehand for your suggestions.
