i can't find H815 MB on the internet and it will cost 240$ to fix it in my country , i found LS991 MB so do you think it will work ?
@foxvb74 - You can do chip reballing. It's much cheaper. You can also try the ILAPO fix with my app:

Did it work? I mean, was the ls991 board compatible with the h815?
you can read firmware from lg devices useing many tools and programs (in download mode without root)
you can't flash firmware of other device be careful you gonna damage your device

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...

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" 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.

So I totally screwed this one up. I installed the wrong KDZ files via TWRP on my 811. I installed the files for the 815 variant by mistake. Can this be fixed or am I up the creek without a paddle?

Ah crap thank you for letting me know how screwed I am, the octoplus is $372. Well I'm gonna take my chances and sent it to LG for repair. This is a replacement phone I got for a boot loop issue.
Hi
I bought the used g4 two days back. In the about section its showing h815 model with android 5(lollipop).
I updated it to marshmellow using LgUp and lg firmware. But after upgrading sim is not working . I reverted back to lollipop and still sim not working.
After not finding any solution i went to the technician , he found the board inside is of h810(at&t) model. While the software is showing h815.
So anyone of you know how to solve this problem. Sim was working before perfectly.

Maybe flash a h810 at&t ROM. Verify the actual model of the phone by removing the back cover and looking for h815 or h810. It's also possible you have a h810 motherboard in a h815 shell.

On board h810 is written. But software showing h815 model. Any idea..?
I believe this is a dodgy repair. As htr5 suggested, I would try an H810 kdz.
I have skimmed over these issues a few times but taken no real notice as I just keep repairing mine through carrier insurance every time I get the bootloop.
Is your IMEI still showing *#06# if sim not recognised now?

Great idea from SavageRobot. Type your IMEI number into http://www.imeipro.info/check_lg.html and it should pull up your phone's model number
I have seen this issue a bunch specially here lately people piecing g4s together.
Flashing diffrent firms crossin.
Go off the imei. This is always real touchy. Cause of cross flashing and bricking. To completly verify. Check imei and pull back of case apart and look at any model nums on the motherboard

It could brick. Just depends on how and what ure flashing. My old g2 was a sprint varient with a tmobile setup on it. And when i try to restore with flashtool it would just fail and give me a cross dl error. Again real tou hy situation
Since my H815T is stuck and i am getting "antirollback version is smaller than tot" even on 815T10H open Australia
Meaning that i have to go for official kdz and my imei confirms that it is an OPTUS Australia phone.
Therefore i need a offical OPTUS Australia firmware.
http://devtester.ro/projects/lg-firmwares/country.php?country=Australia#
have official firmware but when i click download nothing just blank page leading me to
http://pkg03.lime.gdms.lge.com/dn/downloader.dev?fileKey=FW8FBVV1329FAYXCC5FD3M7/H815T10h_00.kdz
Please suggest how to make it work or where could i get official Optus firmware H815T10H.
Thanks in advance.
Are you sure you have a H815?? There shouldn't for any antirollback for the H815T

well... another case to the list.
You must open your G4 and see in the motherboard what model it is. Probably you have a refurbish G4 (maybe LS991 model).

Sorry I can't help with that. That's not simple if it's possible especially if your getting antirollback problems.
I'd suggest returning the phone since it's been tampered with

As you have read in the FAQ sometimes when you send your phone away to be repaired (under warranty in my case) you may get your phone back where what is flashed on it does not match the actual hardware. In my case the motherboard was an H810 and the software claimed it was an H812, even SALT thought it was an H812.
Well the good news is just flash on what your motherboard says it is. In my case the H810 unlock and roms both work great. Everything except for the flashlight works but that is a known problem with the LineageOS 15.1 rom as of writing this. The phone has been in use for over a week with no freakouts, reboots, excessive battery drain, overheating or otherwise.
REMEMBER! caveat emptor, this worked for me and might not for you!
TL;DR you should disassemble your phone and make sure the hardware matches up to what you are using to root it with. And also make damn sure you carrier unlock it first before flashing on a custom rom. The custom roms will not carrier unlock your phone and in my case claim to be successful and fail silently.
One additional thing to note here, I do not know if this was incorrectly flashed by the tech or if putting on the H812 rom was intentional. I did not use the stock phone whatsoever so I do not know if all the hardware (calls/camera/flashlight/etc) even worked properly.
@steadfasterX per request.
Hi, I too have a frankenstein h810 device, but I only realized it after I unlocked flashed a custom rom and everything. I bricked the phone, but I'm using the sd card unbrick method to run the phone. With that said, you mentioned to use h810 files and everything should work fine. I've tried that, but with little success. Either there would be no sound or LTE or no video. I'm currently running h812 roms/modems and my lte does not work and my battery performance is less than stellar.
My question is, what are the current builds of the files are you using? Also, what can I do to unlock my phone? I got the code, but it does not work and you mentioned that its best to unlock the phone before installing custom roms.
One last tidbit, when I go into download mode and try to use LGUP to unbrick the phone, it says my device model is unknown. Is this something to do with the frankenstein motherboard?
Thank you

Ok, I managed to get LGUP running with an edit to the build.prop of the device. LGUP says the phone version is H81220x. I checked the motherboard and it is the same model as baconbacon's LGG4, h810. What are my choices on flashing a proper KDZ? I've read certain things about ARB, but I'm not 100% sure how it works. Looking at the LGUP tool, it wants to select a .tot file. Any suggestions?
