After a few weeks, we should have stock firmware files for these devices. You can usually use the LG flash tool to downgrade to the out of box build.

I dislike skipping OTA updates, so hopefully we can snag some stock images to downgrade if needed.

That's true. Verizon and Sprint always lock things down tight.

Is the community having trouble unlocking other devices running a Snap Dragon 820 and Marshmallow?

Honestly not sure. I'm currently on a Tmobile v10 with a snapdragon 808. We are kinda counting on the G5 guys to help us figure out how to get root working for us with marshmallow now. We've had root pretty much from day 1 with lollipop though. I'm stuck on lollipop for now because once you go to marshmallow their are no downgrades. You try to downgrade and you get a hard brick. Blah.

Does it brick it even if you use the LG flash tool and a tot file? That's always been my safety net. Perhaps I will be disabling OTA updates after all.

From What I understand yes. It "blows" an e-fuse like the Samsung phones. Once it's flashed that's that. No downgrades, period.

I can't find the post where some one mentioned something akin to an e-fuse, but I know it's a hard brick either way for us v10 users who try to downgrade.

There's an anti-roll back flag on some LG phones on some carriers. G4 had it also. T-Mobile for sure. Each version increments the anti-roll back flag #. If you try to flash an older version, which has a flag # less than the # stored in the register, it's a brick. Even if you use 'legit' methods like LGUP. No second tries with this garbage method of 'protection'. At least with Samsung bootloaders, it will just refuse to flash.

Autoprime and I wrote about it on the G4 forums a ways back:
http://forum.xda-developers.com/g4/general/psa-warning-try-to-downgrade-g4-t3197675

At least for the G4, the MM rollback # was the same as the Lollipop one, so you could flash back and forth without penalty. Sorry to hear that's not the case for the V10.

Thanks for clarifying. Good info.

I'd love to jump on the G5 myself given the issues i'd had since flashing a rooted update...but given how poor the dev community was with the G4 and 90% of its variants, there's not much hope for this device going much further than a difficult root process and maybe 1 or 2 custom ROMs at best :( Hope I'm wrong.

The G4 suffered in the dev community because only a few got their hands on them. I didn't even get my H815 until February, after the bringup was done. (And most of that was done without a device in hand, part of why it took so long.)
