How to downgrade firmware


#1

How can I downgrade firmware?


#2

Can you narrow down the situation a bit more?

What device (Photon, Electron, etc.) and what version are you going from and to?

And over-the-air or USB?


#3

Thank you @rickkas7

Photon. Wanting to go back to 0.7.0 from 0.8.0-rc.4. Using OTA.

@Jimmie, have you tried to search the forum for “downgrade”?
The essence is: “Download the system binaries and flash them in reverse order”.

But if you can I’d rather do it via USB.

What ScruffR said.

Go to the release site and download:

Flash them in the reverse order using the CLI:

particle flash DEVICE_NAME_OR_ID system-part2-0.7.0-photon.bin
particle flash DEVICE_NAME_OR_ID system-part1-0.7.0-photon.bin

Note that you must flash part 2, then part 1 when downgrading.

I don’t know why this happens. I would like to downgrade.
I am also using 080 RC4.

I also find it strange that it talks about downgrading OTA in the Particle Updates thread.
