Older G000K9 firmware downgrade?
Hello, so I have a KT3 (i think) running firmware 5.12.5.
I'm a bit lost in all the information available so I'm asking here
From what I saw, paperwhites are jailbreakable on the firmware I'm running, but this being an older model I couldn't find any definite answers. Is it still possible to jailbreak? Or if the firmware is too new, can I downgrade to a supported firmware? I'm keeping it in airplane mode so I don't mess it up further.

As of right now, the list of supported devices is as follows:

Ah, I see, thank you, i see that it is also not possible to downgrade. I also read there about the hardware jailbreak via the serial port. I looked at the list of packages and there are available for the KT3, but again for old firmware versions.
So basically there's nothing I can do with my old kindle.

I'm not sure you are out of luck via the serial port. Take another look at this thread:

Serial port operations don't depend on the firmware version.

So I can flash the package there without any issue, even if my firmware is very new?

That is pretty much the point of using the serial port.
