Unfortunately there’s no way to recover your old Raspbian OS, it’s gone, kaput!
That’s a curious error- it suggests that i2c is setup correctly but that the system is having trouble communicating with the PiGlow. Is it seated on the header firmly and in the right place?
sorry! i am such a retard! i was using the wrong ip address so that means that everything i was typing in was going onto my security camera rips. can we please start over?

I haven’t written step-by-step instructions for doing this yet because it involves a complete kernel recompile and I’m hoping the final process could be a little easier!
There are definitely variations of “works” and this is pretty low on the scale! It sort-of works, but doesn’t push out all the pixel data properly, missing pixels. If you fire out enough data, fast enough, then your own persistence of vision fills in the gaps, but it still looks pretty awful.
We believe it’s related to the memory used in DMA being cached, so the data being output through PWM isn’t the data we’re sending it. The hack currently tries to flush the cache with empty data but this only works some of the time… with mixed results!
Hurrah! Thank @Jon for persevering in the face of adversity. We’re still looking for a real solution, but this should let you damage your eyesight in the interim.
i thought my unit was broken. For now at least it gets four LEDs on the upper right of my unicorn hat to light up. Hope things will be okay soon. Thanks for the effort guys!
