G4 H815 now a H818N after Warrenty Claim, Incorrect Software Version now installed

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 done factory reset though as I don’t think it would have much of an impact. I did a factory reset when I received the phone though because there was a Chinese version installed

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.


Would it brick the phone if I forcefully try and flash a H815 image on it somehow?
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
 
Did you try changing the url? It's in the instructions at the top of the page. For some reason, certain url formats don't work.

I tried that and didn't work for these URL's
http://pkg03.lime.gdms.lge.com/dn/downloader.dev?fileKey=FWB3JYD132O3A717CD02QYR/H818P10C_00.kdz
http://pkg03.lime.gdms.lge.com/dn/downloader.dev?fileKey=FW87DNG232WZAVU70492E92/H818P10c_00.kdz

Try it on your end and let me know if you have any success, I think it is pkg02.azure server comes up as forbidden :/
 
Same here, not found and 403 - Forbidden.

I found these, but I'd be wary of their legitimacy - http://phonefirmwares.com/ccl-lg-g4-dual-lte-h818p-official-stock-firmware-h81810d_00-kdz/

There are a couple of links here, not sure if they're for your country though: http://forum.xda-developers.com/g4/help/kdz-h818p-lolipop-stock-t3389746

Likewise, have a look here: http://forum.xda-developers.com/g4/general/lg-g4-dual-sim-models-h818p-h818n-t3115759

Tried all the links within the first link you have listed and they don't work either, they point to invalid links from http://devtester.ro/projects/lg-firmwares/install.php

Yep they are Europe ones, may not work too well since they are L variant from what I saw.

And yes I have come across that thread before! I found a 10D rooted one for H818P that is listed and valid download. Couldn't find any stock listing though. http://forum.xda-developers.com/showpost.php?p=62075670&postcount=381
Ah well stock 10D cant be found lol.
Ultimately, I'll just wait till a couple months till warranty is fully finished and downloaded the rooted version either 10D or 20D and away I go I guess haha.

Thank you for you assistance!
 
I haven't done that yet, but I reckon they won't be able to assist me because the phone is not from Australia perhaps. Unless I could ask them just to send me a link to the stock 10D KDZ? I have heard they used to have a page where you can download the Stock ROMs for every model if I am correct?
 
The links you get from the devtester.ro site link to the official LG pages.

As far as I can recall, devtester just acts as an unofficial search front page for the official LG kdz archives (I could be remembering that incorrectly though).
