Has anyone tested a ZVG->ZVD downgrade?

[FEGuy]

After sending in a previously-unlocked ZVB phone to LG's repair center, and getting a locked ZVF board back, I was pissed, and Sprint was incredibly useless at fixing the situation. With the ZVD TOT available, creating an unlocked ROM is pretty trivial (aside from the inherent risks of flashing Marshmallow-based custom partitions), but I'm guessing they're going to start shipping ZVG boards sooner rather than later. If newly-refurbished phones can't make use of a ZVD-based ROM, I'm not going to put much effort into publishing one with anything more than unlocking and adblocking.

What is zvgs qfuse increment. Ill ask around and get zvf and ds. Zvf can be to d i believe so as long as the qfuse didnt go up.

ZVF->ZVD is fine, as stated when the TOT was first released. I was skeptical about the TOT at first, but it flashed fine. I can also confirm that the same method of flashing custom ROMs works with ZVD as previously with ZVB/ZVA/ZV9 , it's just slightly harder to pull the system.img from the current TOT.

yea but if zvgs qfuse is incremented higher than f hardbrick can and will more than likely occur with still no means of fix due to a missing firehose dll for qpst to fix it. we have all files but one single .dll
also you will get the dreaded secure boot error
so as of right now i do not recommend trying to downgrade zvg to any other as a precaution
unless someone is willing to risk it

Is there that firehose dll for LG G4? I bricked my phone. When I connect phone to PC is recognized as "Qualcomm HS-USB QDLoader 9008". Is there some way to unbrick it? Thanks
[edit]
My phone is LG G4 Sprint LS991, firmware is ZVG.
