this does work - use minitool partition wizard to create the EXT4 partition (i recommend 1gb)
I have a new problem at the booting TWRP stage:
C:\shield>fastboot boot twrp-multirom-20151112-UNOFFICIAL-foster.img
OKAY < 0.831s>
Adb push supersu.zip /sdcard/

hmm I did try that, then that said directory does not exist. But its working now - strange.
I have a dev unlocked Lumia 820 and can do any testing if required :)
64 GB is a SDXC card. The HD7 only officially supports SDHC, which caps at 32 GB. Plus, there's the whole thing about compatible speeds of the cards. There's a thread somewhere that lists what card are confirmed to work.
yeah i saw it wasn't off...
