Is there any way to downgrade to am earlier version from MM? T-Mobile.
No, Like Apple, they are making it near impossible to downgrade nowadays.

I have boringly used an LG G4 for almost two years now. Just after a few months of using it, I had the bootloop issue, LG gave me another G4 which I've been using for more than a year. But I believe it is time to unlock the true potential of my phone. I've transferred all my pics and vids and similar stuff to my computer, so now it's go time. The only thing is... I don't know what to do.
Model number: LG-H815TR
Android version: 6.0
Android security patch level: 2017-03-01
Kernel version: 3.10.84
Build number: MRA58K
Software version: V20i-TUR-xx
These are the info I think are relevant. I have no experience in rooting whatsoever. What do I do now? (an up-to-date detailed guide also works for me)
Hey,
I still need help for this.
I've checked online and couldn't find anything for H-815TR v20i running Marshmallow.
Can someone come to my rescue?

It's very easy:
You can't unlock your device because LG allows unlocking of the 815 international version and 811 only.
Marshmallow can be rooted on unlocked devices only (so not on yours).
If you really need root you need to downgrade to lollipop.
Downgrading to LL requires a compatible anti roll back version. Search the forum for the code which displays your current antirollback version and the how-to for downgrading and rooting LL
.

Oh okay.
So I can't root my phone as is, I need to downgrade to Lollipop to do that.
Well I was thinking of flashing some custom ROMs and maybe underclocking for more battery life but given that this is my only smartphone I'd better stick to its current state then.
find the service menu for your phone. Google lg g4 service menu. call that number. check anti roll back version (last entry) if 0 you should be ok to downgrade, if not 0 downgrade will likely brick your device.
https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
read carefully and ask a any questions before using LGUP if unsure
after that you can root with https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
or upload your img file and kindly ask someone to root it for you and re-upload it
Anti-rollback version is 0.
I've upgraded to the U11 and want to sell the 10. I want to appeal to the broadest audience (probably in the US), so I'm trying to figure out the difference between the US Unlocked version and the WWE version. I believe the US version is the most generic, meaning it will get OTA's before any other version, and would work on the most carriers. Is this correct? Is there any reason I would want the WWE version instead?
If someone with Verizon buys it, I can convert to that version for them, but I'd rather go basic vanilla if possible.
thanks

Put it up for sale. When you get a buyer, convert to the appropriate stock ROM version (with MID/CID) and lock the bootloader, then go S-On.
Being S-Off could be a selling point though.
There have been sites that claim they have the firmware but say you'll need a premium account. If anyone has access to this firmware, it would be highly appreciated. Im using HK HTC M9 with unlocked bootloader and S-ON but when I flashed ARHD, I get No SIM signal. I'm trying to get back to stock or if anyone has any idea of a custom ROM that would give me SIM signal that would be great as well.
The latest ruu for your M9 is marshmallow: https://androidfilehost.com/?fid=673368273298946916
You can't flash this ruu if you're on higher version with s-off.
Theoretically all himaul nougat roms should have signal on this firmware.
Thats what makes it weird! My stock ROM was Nougat but there are only Marshmallow firmwares online

What is your current CID and MID given in fastboot?
It would be a good idea to share all the info, except imei, from fastboot.
It might be the CID and MID has been changed hence you got nougat.
Did you got it from ebay or something like so?
Guys, there's nothing special about this situation. All M9 variants got updated to android N/firmware 4.x.
You need to keep in mind that RUUs don't get distributed officially (well, except for the US ones). They get leaked by insiders and no one knows if or when a RUU for a non-US firmware gets leaked.
@lucyr03:
That isn't the latest RUU. It's only the latest one that is freely available. Most contributers just moved on to newer devices and therefore, no one has bought newer RUUs, yet. You can find a 4.27.708.3 RUU* e.g. on easy-firmware. Someone would need to buy and to reupload it to AFH, though.
* The needed file is called
0PJAIMG_HIMA_UHL_N70_SENSE80_MR_hTC_Asia_HK_4.27.708.3_R3_Radio_01.01_U114401031_124.01.70203G_F_release_507839_signed_2_4.zip
Edit: Here are the easy-firmware links for the other hardware variants of the M9

Hi, ive read a couple of threads to unlock the sprint lg g5, in my case the hiddenmenu call apk doesnt show all the options, and i understood this may be because of my software version, is there some way of downgrade o change the software version? Is the ZVF the latest? Thanks!
Yes this is the latest security update, and there is no possibility to downgrade it

It sounds good to me, but when I felt the impossibility of not being able to downgrade I was forced to sell it as a tmobile device, since for some strange and not logical reason, it did not register on the sprint network in any way and the only option that sprint gave me is to send it to warranty:crying:
