So, you’re upgrading from a very old version:
- do not keep settings
- make sure you don’t have an ekh01v1, ekh01v2, or ekh01-03
It’s unlikely you want to flash this image, because if it has 2.2 on it there was no 2.2 image built for an “ekh01”.
Historically, the order of devices is:
ekh01v1
ekh01v2
ekh01-03
ekh01 (covers any other ekh01)
But confusingly, the ekh01v1 will likely just say ekh01 on the sticker.
If you’re not sure, post what’s on the sticker.
