KDZ flashing - G4 Q&A, Help & Troubleshooting

Hi I have a H815 G4 from EE uk running fw version v10b-230-30.
Can I flash any eu H815 KDZ to upgrade fw?
Sorry for the noobness I'm coming from 4 years of Samsung and this is my first LG.
Thanks in advance [emoji106]

Hey guys,
as long as it's h815 and without any suffix, it should be fine.
I flashed the EU one on my SEA version, works well.

Please forgive my noobness. I've only every owned Samsung until now.
What suffix? I have a H815P here in South Africa. It came with v10b but upgraded to v10c after rooting with the low effort method.

yeah, I mean THAT suffix.
The European G4 is H815 (no T, P, or anything after the number). Other variants have some suffix after the number, such as the Taiwanese one (h815T).
SEA G4 has the same model number as the EU G4 (H815) so it can be flashed with the same KDZ.
I haven't tested out other models yet, so I can't comment on whether flashing the h815 KDZ on them will cause any kind of problem. Best be safe.

So the H815P, H815T and whatever "similar" variant/with a suffix could be flashed with the same ROM? leaving the H815 and the SEA to be flashed with another/same ROM.
Is that correct? I also a long time Samsung owner and coming to LG has me all confused.

H815p - need to be flashed with a H81P kdz
H815T - need to be flashed with a H815T kdz
Simple as that.

Can H815 kdz flash in H815T

I have a H815T model G4 and it is 10a version now.
So can the H815 firmware flash in H815T model?
Do anyone try it before?
THX
I have the same question as the user above. I am using h815t with an australian kdz and i am located in the UAE. the bands work fine. i really would love to have android 6.0 on the phone. anyone with info on possible side effects of installing h815 firmware on a h815t?
any answers???
Yes u can flash H815 kdz to H815T
I haven't faced any problems after flashing a 6.0 Marshmallow H815 kdz to the H815T (Hong Kong version) it was very snappy and fast. I flashed this kdz without wipe using LGUP from Android 5.1
I installed V20B TWN on my H815T through LGUP and no problems at all.

LG G4 H815 American Ver?

Hi i bought a lg g4 used, and the software says euro. sw orginal version is: lgh815at-00-vx10b-global-com-may-01-2015 and sw ver info is: h815x10-eur-xx, when i tried unlocking the bootloader it said it is an american device. I thought american lg g4 were h810/811/etc. Im a bit confused so if someone can guide me, I would really appreciate it. I am trying to unlock the bootloader and root my phone. Since lg wont let me unlock bootloader, i just want to root it and which model rootedimage do i use?
Lg made a carrier free GSM H815 version for the US. Sounds like the seller flash a euro version KDZ over the US hardware to make it appear as a euro version. However, since it is not a true Euro version, it can't be bootloader unlocked.
Use the H815EU root method.

This is the LG G4 Trial USA version they gave free to USA before its selling in store. They gave me one and I rooted it. Now its on V10e-EUR-XX.

Yeah. Unless you have a preference for CM/AOSP, I would root it and install Xposed with the G4 Tweaksbox and go with that. Pretty much the same as the current ROMs that are out there now.

How were you able to install genisys rom on H815 USA variant? I thought you couldn't flash these versions?

h811 VS h815

This is going to sound like a noob question, but I have been a HTC user for the last 3 years (M7 and M8) and LG is a little different.
So, I always check this XDA page for useful information when choosing a phone. I have seen 2 versions of the LG G4: h811 and h815. What are these and what is the difference?
Also I am deciding between the G4 and the OnePlus 2 so what do you think I should get?
Thanks is advance!
i'm guessing h815 is the international version

H811 is t-mobile. H815 is international variant. If you do get a G4 you'll want the H815 but look for the european model or else you won't be able to unlock the bootloader and install new roms (cyanogenmod etc)
You can unlock, root, and ROM them both. You just have to carrier-unlock the 811 if you take it off T-Mobile.

Is there any way to tell on these phones on amazon or anything that I am getting a h815?
Thanks BTW!

LG G4 H815T (Hong Kong)

Assalam-o-Alaikum (Peace be upon you)! Hi !
I have a LG G4 H815T Hong Kong version. I was not receiving Marshmallow Update on it and had v10B stock firmware on it. Then I decided to manually flash KDZ on it but first I tried to flash a same v10B H815T Hong Kong KDZ on it (Only to check process). After flashing, my Model No. H815T changed to H815 . After that I received update through LG Bridge to H815v20h. I installed it but LG Bridge installed a Italian TIM KDZ on it due to change in model no. then I reinstalled Stock Rom H815Tv10B Hong Kong but Model No. is H815 instead of H815T . Also installed other European KDZs but they show a message "current version is not available for user. can't find matched cust" at start up after boot.
How can I change my Model No. back to H815T without root? If root is the only way then can I unroot my phone after making any change. Will my phone work same as before root? also is there any H815T update available after v20e or v20e is latest? I have installed v20e H815T but model no. is still H815 and v20e is slow in game performance than v20h .
Thanks in advance for help.
Hi. Did you have your problem solved?
I would rather install v20j for UK.

US Variant H815 rooting question

Before anyone asks, yes I've searched, but have not been able to find any solid answers. So here I am. I just bought an LG G4 from ebay, I was listed as a T-Mobile model but when it arrived, I discovered it was a US model H815. It's running vx10b-eur-xx. These apparently have locked bootloaders. My question is, is there any method I can use to root this device and run a ROM like CM14, or am I stuck with what it's got? Like I said, all my searches never really come up with a for-sure answer. (hopefully this is in the right spot)

Apparently there is a US Variant H815, when I attempted the unlock the bootloader the LG developer website stated that the device could not be unlocked because it was a US model. Not the exact quote, but close enough. Thanks for the reply though.
