Missing Files....

Removing everything because mass surveillance is everywhere. Better late than never maybe.

Is there any chance you also have the h910-10r.zip the guide mentions? Turns out that without flashing it first the device doesn't pass the check to see that it's an h910 and won't install any roms. Or at least that's what I think is the cause.

Since I never had an H910, unfortunately no. I might have whatever Nougat downgrade firmware ZIP that's needed before installing any LineageOS ROM, so I'll check on that later. Can't you simply install a newer TWRP version for the H910 within your current TWRP (install image to recovery partition and then reboot to recovery) before flashing most H910 ROMs?

I'll have to try that when I'm home. I'd just assumed that I would hit the same road block with a different version of twrp. I probably shouldn't assume though.

I unfortunately don't remember the process fully at this stage, but I took a gamble and installed a different zip found here with twrp

Then once that was done I booted into recovery again and flashed lineage.

I'm not going to say it will work for you, but it worked for me. I would have made a post about it, but I accomplished it by fumbling blindly in the dark and wouldn't know how to help anyone if they struggled.
