Just wondering if it matters which KDZ file you install into your device or not? I've seen so many people flashing 10L in the past few days, posting links to the cdsmg download, some are international, some are eur, some are for 32GB or 16GB variants. How do I know which one will work with my phone without actually trying it? I've checked on the website where you type your imei number and it says latest version for me is 10J
Hello,
Long story short, I have obtained my phone back from repair in Hong Kong (I am located in Australia). Originally the model of G4 was a H815 using software version H81520D_00_0115 I believe from memory. This phone died because of it overheating causing to do a boot loop/stuck on LG Logo screen.
I ended up getting the phone back from Hong Kong, they replaced the mainboard as I thought and now the model of the phone thinks it is a H818N Dual Sim card LG G4 – Running software version V10c-DS1-HQ, which it clearly is not a dual sim card G4 because there is no additional sim card slot. Anyway, phone seems to be working well except the rear camera does not focus (I have had this issue in the past and I resolved the issue by installing the correct software version, eg 20A, 20C, 20D etc.) Trying to update the phone using software update does not reveal any updates. Using LG Bridge reveals an available update for it, it thinks the software version was 20F or 20H not sure, however when it goes to download it does not get past 0% tested on two PC’s.
I have installed the images I have found for the H818N now which are:
Hong Kong H818N10b.kdz (this one worked the best as it didn’t come up with that error message when you reboot if it’s an incompatible kdz image)
India H818N10d_00.kdz
India H818N 10F.kdz
With no success in fixing the rear camera issue. I have not factory reset though as I don’t think it would have much of an impact.
Have tried to loading: H81520D.kdz image but the LGUP utility (which I have been using for the above process) says KDZ file is invalid, I assume this is because it detects the phone as H818.
Does anyone have any suggestions or locations where I could download more images to try like H818N 10A,B,C etc? Or if there is something I should do cause I have had nothing but issues with these phones
Kind regards
sorry for poor English first
since having a bootloop issue, I sent my H791 16GB version to China for repair followed those has the same issue,
and I upgrade ram as 4GB and rom as 32gb,
now my phone is back and looks everything works fine.
the only thing confused me is the variant in bootloader shown as LGH790 , which is US version...and IMEI code also changed
since my carrier in Taiwan needs band 8 for LTE...
if someone can teach me how to flash as H791?
at first I think I only needs to flash radio but I found the description in bootloader for H791 and H790 has no difference...
Hello all,
I bought on ebay a couple of G4 at a good price but I discovered only at the arrival they are H810 and not H815 models. It was stated in the description but I did not understood the difference, so it's my fault.
The main issues are two:
can't update from Android 5.1 to 6 without an AT&T subscription
doesn't support LTE band 20 that is used by my carrier Vodafone Italy so I have almost no 4G coverage
For the first issue I tried the forced FOTA method using ADB: I put the 20N.up file (using the specific AT&T MarshMallow for H810 foung in XDA) in the internal memory but the process does not complete after the reboot saying that the update service is not available
==> The second one is the worst one and I think I need either to enable extra bands or try to convert the phone to a H815, if the modem hardware is the same. I tried the hidden menu but under Field Test->Modem Settings the Band selection is not present!
So I ask to you experts if I can use a flashing tool like LGUP to flash my H810 with an H815 software and how.
Thank you!

you cant cross flash firmware as att has locked BL you will More than likely hard brick if attempted.
But you should be able to flashtool or lgup to the newest firmware that is released for your device.
So I have my v35 actually going to be discarded, and I decided to buy a cheap G8 from [email protected] and I am confused about the Android 10 update... Some users reported that if the phone is on Pie and skip all the set-up for first time and connect to wifi without any sim card they have upgraded their phones to Android 10, other suggested that they changed the time zone and it worked eventually, others reported that they got a [email protected] sim card and they inserted and after a couple of minutes or hours the update will automatically downloaded.
As someone who live outside US I import my phones because they are way cheap than here in my country and I have enough knowledge of flashing software as I did with my v35 also that was or it is [email protected] But now I see that the Android 10 kdz is on the LG site for flash? As I had to or wanted to install Android 10 on the current v35 as it is unlocked I had to flash the korean version...
My question is if I can flash using LG bridge the current Android 10 kdz or it's not possible on the [email protected]? Or I need to buy the [email protected] sim card or how the heck it's the correct way to upgrade the phone? I have to sim unlock the phone first or should I have to do without sim unlock?

Sorry, there's basically no way to update. You can't cross flash, and at&t doesn't provide kdzs. The only way to is to buy an at&t sim, but you have to activate it, which costs like another $60, and you need to actually connect to at&t, which can be done practically nowhere outside of the us I think
Mmm even with the official page of LG having Android 10 kdz? They are listed as unknown and CAN, and some of them are listed as US too, just wondering if I had to do the same as I did with the v35, which also as being of at&t and unlocked it was never going to receive the Android 10 by ota. I just flashed the korean kdz and it worked and of course it is different.

The thing about activating I guess I can't as I am outside USA and by $60 I could anyway it's way cheaper than paying retail prices here for $800

You can't cross flash, end of story. Lg put in new hardware locks against it
Ey pardon for insisting but... T-Mobile and Verizon are way easier to update or it's the same mess as at&t version? Saw a couple of them unlocked one of T-Mobile and the Verizon one seems black listed but for overseas in my case works.

I don't know if they work overseas when they're blacklisted; I wouldn't be too sure of that. Those variants should be fine because t mobile and Verizon provide kdzs, so you can always update manually
Yeah I asked on Reddit and people say T-Mobile updates ota and are on Android 10 and of course they advised me never again buy any at&t variant and even Verizon can update also ota.
