Ok. I decided to give NAND a try on my backup phone. I got adb loaded up ok, loaded RHODIMG.NBH onto the phone. I get the minipooploader blue screen, and fastboot devices returns a name. So I think that is all good.
This is where I am stuck. I seem to be missing a step. I put recovery.img into
C:\android-sdk-windows\platform-tools>
I get this error. When I try to flash.
C:\android-sdk-windows\platform-tools>fastboot flash recovery.img
unknown partition 'recovery.img'
error: cannot determine image filename for 'recovery.img'
Could someone give me a hint please?
