Is it possible to downgrade Android Marshmallow to Android Lollipop (5.1) so that I can flash this ROM?
[G4 General] Engelm:
Yes.

Use lgup, tick upgrade. Then you can select the 5.1 kdz File.

After that you Tick refurbish und click on start

Now i flash v29 firmware to my h818p. All ok except android pay.

[G4 General] andrea1493:
True :)
[G4 General] ling751am:
So.. this H815 EU v29a firmware can flash to a rooted H818P

What will happen if I flash this firmware to my Rooted H815 Int. (Locked Bootloader)?
[G4 General] datscoolmetoo:
well, i've just flashed the whole firmware using flashfire. what will happen if i flash other H815's roms like lineage or sth?
[G4 General] Engelm:
Magic Happens...

It depends on....

What device u have, which model,

BL locked or unlocked.

But after your question I guess that your bootloader ist locked so don't try to flash a rom which is not signed by LG.

Your phone will know that you are trying to start something different and prevents the phone from booting this rom.
[G4 General] goran_oh:
Thank you.
[G4 General] datscoolmetoo:
The thread title says it all about the phone. A damn locked h818. I was wondering if i've done flashing an h815 firmware through flashfire so am i able to go through the process with another h815's rom like lineage as well?

Also OP once suggested H-ROM(it's for h815) before
[G4 General] Engelm:
No, I would not say that he suggested H-ROM.

Because it does some Kernel-changes (something like that I think) and because of that your phone won't boot.

In the thread of the H-ROM it is said that you need an unlocked bootloader.

So no chance.

Flashfire is about the same as Fish, so read these limitations, it's about the same I guess (https://xdaforums.com/android/software-hacking/locked-fish-hack-to-boot-want-device-t3578373)

We sadly have to wait until he will find a universal bootloader-unlock.

I hope he will find one solution for all of us.

You could also have a look at his 'WIP' Topic about unlocking some LG G4 bootloader.

Will it work with LG h818p Indonesia v10l rooted but no support for unlocking bootloader?

[G4 General] uzeroni:
Hi! I've followed all the steps, and after the FlashFire recovery screen and the LG boot screen, it's been stuck like that for 30 minutes. I decide to go into the recovery and do a factory reset, but after clicking okay, it reboots into a screen that says "Your device is corrupt. It cannot be trusted and will not boot."

I think this has something to do with the bootloader, but afaik after downgrading to 5.1.1 and rooting, there's no way to unlock it? How do I resolve this problem? Thanks!

Edit - device is H818P, flashed with BRA V10d
[G4 General] Engelm:
What did you flash with Flashfire?

The LG-H815_Official_v29A. ROM?
[G4 General] uzeroni:
[MENTION=6409296]Engelm[/MENTION] Yup! The one linked in the OP.
[G4 General] Engelm:
Well, sounds not so good.

Looks like I had a lucky day :/

I would ask user steadfasterX for help.
[G4 General] uzeroni:
I guess I can always just start again with the kdz, no biggie. Thanks!

And [MENTION=5545101]steadfasterX[/MENTION] , would you happen to know anything about this matter? :)
[G4 General] braulio_holtz:
middle off Topic, but it's because I'd like to install Nougat.My PC does not recognize my LG G4, I tested with three cables, one of them I believe is already bad, the device charges in USB, but the computer does not recognize the driver, I tried to reinstall, but no success.

Does anyone have any idea how to solve this? What was I doing wrong?
[G4 General] harysviewty:
What h818p is this? Is it working with locked bootloader? I'm on Indonesian h818p locked bootloader lolipop v10l rooted. Is it necessary to install Brazilian firmware first?
[G4 General] nerdo:
Yes this is for a H818P with locked bootloader.

Since you are on rooted Lollipop you can go straight to flashing Nougat as detailed in OP.
[G4 General] Engelm:
It may be not, but who would test it?

I did everything like in the first post and it worked.

This is a simple rule, do everything like it is described else no one knows why it does not work.

But you could try, be the first one and tell if it works xD

When I downgraded 7.0 to 5.1, I lost my signal, I tried to use the LG UP to flash the ROM stock, but the problem continues. Has anyone managed to fix the signal problem?
[G4 General] harysviewty:
Let me report here. LG Indonesian version works great, no heating, much better battery, faster performance. Sadly, the g4 g5 V10 camera, all of them I've tried, they can't change the exposures whenever we touch any part to focus. The focusing is so slow and lots of time quite often it tends to missfocus so bad and can't help to even trigger touch tap focusing. The flash light works weird, rapid torch blink that often turns into major blank images. Sometimes it's hard to knock-on, and knockcodes only work with minimal 6 taps in 3 quadrant. The signal is so much worse in reception and actual speed. The screen looks warmer too yellow. Glance view, quick cover, always on voice recognition, smart Lock trusted faces, all can't work.
[G4 General] crimsonraptr:
Hi. I am planning to this to my H818p. Anyone else who could confirm these issues?

PROS and CONS? :confused::confused::confused:

EDIT: [MENTION=7806114]harysviewty[/MENTION] : did you upgrade from H818N or H818P
[G4 General] harysviewty:
H818p that's all what I've found about the bug so far
[G4 General] uzeroni:
Update, re-downloaded and did everything. G4 is still stuck at the bootloader (LG logo and flashing blue LED)

Does this mean I can't update with this method for good?
[G4 General] goran_oh:
Can I update my h815 via lgup with this kdz 29a?
[G4 General] kazantip1288:
can someone fix an android pay on this rom?
[G4 General] Engelm:
I can't confirm this issue (H818P).

My camera is working great, I can take photos of sheets with flash and is looks good to me.

And knock-code is also working fine :)

But maybe I had just luck, don't know..

my phone turned off after selecting "Flash" button and until now it still off.
[G4 General] datscoolmetoo:
Just take out the battery, put it again and turn on the phone.

You need a fresh rom for flash using flashfire. Do a factory reset then try to flash it again

---------- Post added at 03:52 PM ---------- Previous post was at 03:43 PM ----------

Yea it does work but you can extract kdz, extract kz, merge the system.img and finally save modem.ini using ext2read tool(you can find the tutorial here>> https://xdaforums.com/showthread.php?t=2600575) afterward u just have to simply rename modem.ini to modem.img

I have tired all found solutions, such as "Reset Network Settings or wifi calling config and many other solutions" but I have not tired yet rewriting QCN file from a other working GS7 TMB device.

do not ask me how i did unlock the phone because i have paid 100$ on ebay and unlocked remotely but they did not fixed network issue and not refunded, because phone is really unlocked and according to the person who did this is my problem.

so my question is please can somebody Read QCN form their device and send me the file to flash to my device? I have found too many forums that the solution was QCN file but there was for other models and i have not found the file on internet for GS7

dont worry about personal data, such as imei and SN, because these data are stored to EFS directory and QCN will not include these type of data.

thanks
