I was one of the original kickstarter backers for Slice and I've been looking to repurpose it to a PiHole on my network (I have another Kodi these days).
I've been trying to follow the old links for the builds - and it all looks pretty much dead end except on LibreElec. My latest attempt has been to use the LibreElec build to help in installing 32bit Raspbian on the CM1 flash - and copy the dt-blob.bin over release - which works fine, until the OS performs an update and bricks the unit again.
Any advice at all? Reading the pages it mentions patching the Kernel "upstream" at GitHub - FiveNinjas/documentation
Its the perfect box to run as a PiHole and Webserver if I can get it going.
