Downgrade 1.2.1 To 1.2.0 Possible?

[Eso Rimmer]

I would like to try GP2X (firmware 1.2.0) but I have Kingston 512 which will work only after upgrade to 1.2.1. However I want to use 2GB A-DATA later so if I upgrade to 1.2.1 I will lost 2GB support according to GPH notice. So I will need to downgrade back to 1.2.0. Is this downgrade possible? Or I missed something?

You could downgrade to the original firmware using DJWillis' guide here: http://www.distant-earth.com/gp2x/2005/11/...cked-gp2xs.html and then upgrade to the one you want. I don't know of a quicker way.

You can get the 1.2.0 kernel on easy enough just by reflashing, but you may find the video player stops working, so the only guaranteed way would be what barnesy suggests - use DJWIllis's debricking guide to go back to an earlier version and then upgrade to the version you want.
