Is it possible to downgrade N0110 from the v20 beta to a Phi compatible version (v18) without the use of a Raspberry Pi?

I tried to downgrade using the guide but my device refuses to boot (stays on the recovery screen) after flashing the v18.2 external.bin.

This may be because you have a newer bootloader which keeps the calculator from being downgraded to 18.2 (so you're gonna need to use the raspberry pi method) (I'm not 100% sure someone confirm pls)

It depends of the version you had, if it was e16-18, it should work, else, it can't

this is for e19, but i'm not sure it works for e20
