Flashing back to 1.0.9

So where would I find the file to flash to the sd card for firmware 1.0.9? I found it for the new firmware 1.2.1. I also found the update firmware for 1.0.9 but not an image file. I’m lost, please help.

Hey Greg,

you find all versions under

The full image of 1.0.9 is on that page too, the direct link is onefinity-raspi-1.0.9.img.xz

How can full image of 1.2.1 be 4.7 gig but the full 1.0.9 be only 280 meg.?

Hey Dave,

it is not, the compressed archive file onefinity-raspi-1.2.1.img.xz is 446 MiB (=468 MB) big and it contains a bootable Raspberry Pi OS image of 2044 MiB (=2143 MB).

The compressed archive file onefinity-raspi-1.0.9.img.xz is 293 MiB (=308 MB) big and it contains a bootable Raspberry Pi OS image of 1941 MiB (=2035 MB)

Are you refering to the fact that after flashing a Raspberry Pi OS image to a SD card, at first boot the filesystem is automatically expanded to the maximum available space of the SD card?

Sorry, i was thinking the 1.2.1 was a bigger file than it was. I went back and checked it.
