Help required H815T10H - G4 Q&A, Help & Troubleshooting

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).

Alright opened my mobile and it have EAZ66585501_H810_MAIN_1.0 written on it. What does it mean?
And thanks to you guys and your prompt reply that we still have hope for our devices.

Thanks for the tip. Now how can i flash H810 firmware. LGUP gives error "invalid tot" when H810 tot is flashed.

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

Install t-mobile rom onto h812 possible?

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...
Yes you can
I've made this tutorial but you have to change some thinks to use in your variant
PS: you will get some problems with your modem (dont work)

But you have to flash first with lg flash tool 2014 (flash others kdz without problem)

Hello friend,
I am also thinking of flashing H815(international) rom onto my H812(Canadian) hardware. If you don't mind, could you please tell me how did the phone function with the H815 firmware?
Thank you very much. Your help is greatly appreciated.

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" ...
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.

Difference between lg h811 and h815t?

So I opened my box today and realized the manual mentioned lg g4 h815t.... I have a h811
Looked up on website both are T-Mobile. What's the difference?
What phone do I really have?
Could I potentionally flash a h815 ROM?

The H815T is Not T-Mobile. The H815T are sold in Turkey and Hong Kong. It's mostly the same as the H815 variant.
If you flash an H815 firmware on your device if it's a H811 you'll permanently brick your device.

LG website states 815T is a T-Mobile phone.
It is possible the manual just has that model number listed and shipped with my 811 device.
How do I really check what version I have?
And why would they state 815T is a T-Mobile phone on their website?

I see no where on LGs website on the H815T page stating it's T-Mobile. If it does it's a glitch. It's 100% not a T-Mobile USA device.
Manuals may not matter as a G4 is a G4 operation wise.
What do you mean check which version you have? If it's a H811 then it's a T-Mobile device. T-Mobile only has 1 model for the G4.
Where did you buy your phone? If used/referb/second hand that might explain the manual mismatch.

Bought it through Rogers. Apparently rogers sells or sold h812
Box imei and serial number match to phone.
Must be manual...manual is a manual.
But why would Rogers be selling a T-Mobile phone.....when they have their own brand?
Anyway to check other than software?

Now that is what's odd. So you bought it through a actual Rogers store? And not a reseller that just happens to sell rogers stuff?
Rogers themselves I doubt would sell a T-Mobile device.

It’s not that it’s not been tried. It cannot be done. If it is you’ll 1. Result in a brick or 2. It won’t work and hope that you’ll be able to flash it back.
The modems in those phones are completely different. Along with the T-Mobile model having antirollback which makes it impossible

Ok well I have the H812 with antirollback value 0. once steadfasterx is fully complete his unofficial bootloader unlock, my plan is to unlock bootloader, install TWRP, then until custom roms for this variant comes out, I plan on flashing other carrier firmwares.... and it seems H815 has better updates, so probably going to flash that one...
Also, can you kindly tell me what you mean by "modem" in the phone? is it the thing that deals with frequency bands?
If it softbricks, I can always re-flash my stock firmware right? What are the chances of a hardbrick?

H812 won’t be as locked down as the H811 is. But flashing wrong model firmware is a no no. Flashing custom roms built on another firmware may not work correctly but won’t be as harmful as flashing stock firmware which will 99% won’t work and or will cause a hard brick.

Not saying you can, but that would be possible before flashing a stock kdz or tot.
Sorry no clue on Roms. Only keep up with stock and flashing to stock.

[UsU]Dealing with a Frankenstein H810 device

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?

You should be able to.flash 812 software on it then. Google 20v kdz for 812 and flash it with lg up. If .kdz extension isn't available select refurbish....it can be tricky but eventually it will give you option to flash kdz

You could try a factory restore if you haven't already. Also, the LG Bridge app for your pc (download from LG site), may provide an update or an option to reinstall your firmware.
The alternative is to check (private message) with other H810 XDA owners in relevant threads to see if someone has a copy of a suitable stock firmware.
Note: If you want to install a custom rom to update to the latest security patches, etc., , you can unlock your bootloader unofficially with steadfasterX's brilliant work (many H810 users have gone this route now) - check it out here: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU. Read the OP thoroughly and make sure you understand it fully. You will have to have an ARB version of two or less in order to go this route, so before upgrading to any other H810 firmware, check your ARB version with SALT.

Read the OP thoroughly and make sure you understand it fully. You will have to have an ARB version of two or less in order to go this route, so before upgrading to any other H810 firmware, check your ARB version with SALT.

thanks for reply.
I already tried the factory reset, but no lights on.
Tha LG Bridge won't work as i know cuz i don't have active AT&T Sim card and i don't live in tha usa.
Asking other H810 XDA Owners for a suitable stock firmware, i really didn't think about it so i will give it a try.
My H810 already have H81021y software which has ARB 3. so no root for me, i guess :crying:

Yes, no root, no bootloader unlock for you, unfortunately.
However, ALL MAY NOT BE LOST ... check out this thread that I found: link... to Android 6.0 MM h81021y archive tot
There are a couple of links to the firmware you seem to be looking for. It is a TOT file but you should be able to flash it following the TOT method as outlined in this thread: [Guide] LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method - scroll down to the TOT method.
Good luck.

Could also be the ilapo if a factory reset does not solve it.

uhm what about using the search box ???
Also find the bootloop fix list in my signature .
Still its just a guess . Check the first 3 digits of your serial (sticker behind the battery). If it starts with 603 or lower you board will be sooner or later affected by the ilapo .

As long as the kdz your cross flashing is not a T-mobile kdz. You should be fine you will lose wifi calling and such.

Thank you, it worked. When I check the hardware info it shows LG-G710ULM, does the Canadian AWM = ULM?

Crossflashing does not change your phone model. Yes it will say that just remember what kdz your on?

I flashed G710AWM20c_00_1025.kdz, but strangely says G710ULM. My original phone model number is G710VM.

Cool, thanks.
One last question I have is, can I update the software through the updater?
If not, when I do an "upgrade" option through LGUP, will it wipe my phone data, or will it be like any other update through the updater on the phone?
Lgup will wipe data. Going through the software update in the phone will keep data as long as you are on stock. If you are crossflashed to anther kdz software update in phone wont work. You need to manually update with lgup.
