Possible to revert from stock Nougat 7 to MM 6 ? - T-Mobile LG V10 Q&A, Help & Troubleshooting

Has anyone successfully reverted from Stock nougat 7 to MM 6? I find Nougat runs sluggish on the LG V10, or maybe I just haven't used the V10 for so long(recently replaced out of warranty for bootloop and defective LCD) I forget how slow it is compared to even my HTC 10.
Thanks

I believe @runningnak3d is currently working on this.

I've been messing with my lg v20 and downgrading to previous versions of nogaut using uppercut(autoprime tool) and lg up. I will try it with the same methods and let you know if I end up bricking flashing a mm kdz

In for results

H831 - Revert from nougat to marshmallow?

I have an LG G5 H831 from WIND/Freedom mobile which I recently upgraded to Nougat.
For some reason I don't like the new update and I'd like to revert back to the stock firmware. Is this possible?
I've looked around this forum and I couldn't find anything helpful.
Please help.

I agree. Android v7 is the Windows ME of mobile operating systems. Too many great features removed, excused by positive sounding mumblings and overbearing rhetoric.
If you can find the LG-H831 DLL for LGUP then you can flash a H83110d_00_0711.kdz ROM image (you can find or I can put up for you). I cannot find a H831 DLL for LGUP anywhere though so if anyone has one please let us know.
I'm a complete noob when it comes to flashing LG phones.
Is there a tutorial I can follow?
Where can I download the files needed?
I'm very happy with this phone btw. It's very snappy, works well and the camera is simply awesome!
It seems to me that Nougat is using more RAM than Marshmallow and that concerns me a bit.
I forgot to mention something.
Few days ago I was able to find the KDZ files here, but they were for Rogers/Fido. I was very cautious and I did not flash them.

Need to downgrade from N to MM

Hey yall! I hope this is in the right place, if not my apologies. I got myself a G5 and I love except i made a terrible mistake...I upgraded the system from Marshmellow 6.0.1 to Nougat 7.0 and my phone has had nothing but problems and glitches. I want and really need to downgrade this phone to 6.0.1 but I have no idea how and id rather not brick my phone. I have been over several forums already on this site and none of them have the same procedure. One says i need to download this another says i dont need that etc etc.I would like to downgrade to 6.0.1 easily and with minimal risk if possible. If someone could give me a clear easy to understand step by step guide that would be much appreciated. I have the Canadian H831 running android 7.0. Software Version is h83120a. If you need anymore info please let me know.
Thank you in advance

I use android 7 on my H850 and it's smooth, as I can see here, you're using the initial​ version of android 7 (20a). Have you try to check if there's any newer Nougat version of your model (H831) through OTA or LG brigde or kdz?

You need to download the Android 6 kdz. You can check here for one specific to your model https://forum.xda-developers.com/lg-g5/how-to/list-lg-g5-stock-kdz-firmware-t3365941. Once you downloaded the kdz use LGUP or uppercut to flash it to your phone. If you're unable to successfully flash it (like it errors out every time), it may be that you can't downgrade to MM from N. I'd try to use LGUP first, but if you can't get it to work try uppercut. Read those threads for instructions on how to use the tools. Feel free to ask more questions if you have any and I'll try to answer. Hopefully this helps.

Here's another source for H831 KDZ files: https://lg-firmwares.com/lg-h831-firmwares/#more-1685 Links to a number of MM ROMs can be found there. I have no experience with the H831, but I have successfully downgraded from N to MM on my H850 with LGUP. You should be aware, though, that there have been a number of reports of downgrading problems with the G5.
Make sure you read instructions carefully! Downgrades are easy to hard brick aka all bad.

You would have to use lg up and then find a kdz file for your variant of the g5. Then boot into download mode and select upgrade and then start

Back to stock - camera and torchlight broken

Hi!
I gave my old V30 away that ran custom ROMs quite a while and flashed it back to stock for that, since the new owner is not a techie. I used a TWRP-flashable stock ROM for this.
But now neither camera nor torchlight do work.
Did I forget something?
You'll need to tell us what ROM you came from. Pie ROMs, for example, can't be TWRP-flashed back to Oreo. Other custom ROMs have even bigger issues.
I would recommend KDZing back to stock. If you're going back to Oreo, you may need to go back to Nougat and then up through the others into Pie, because some of the Oreo KDZ made incremental changes that are needed for Pie. At least that's my understanding on the matter...
Safest would be to back to KDZ Nougat, then go through the rest until you're at the version you want... but there may be some shortcuts.

WHAT stock did you go back to? Oreo or Pie? If you were on LG Pie (and custom ROMS needing LG Pie), going back to stock LG Oreo breaks flashlight and camera. Warnings are listed in the Pie KDZ Guides about this. You have to flash back to Nougat to scrub out the remnants of LG Pie and then you can go to Oreo.
Sometimes even then you have to still run in "permissive" mode to let camera and flashlight work right.
