I have a MX III 2G (I think).
I've tried many images but I can't succeed to end a boot.
I have flashed the dualboot zip file successfully. It tries to boot from sd but or I have a blank screen or, with latest RC 2 , I have a message of corrupted fs:
Corrupt System/Repair Failed (and fails the check).
Can you confirm which is the correct image for my device?
You might want to try it in USB (try all ports). Write a new version to SD and do the toothpick thing then reboot but don't let it do the file-check thing, which it seems to do because its not correctly set up to boot from SD for this particular box. Then reboot with it in USB (if you have a USB card-reader). Try all ports. Mine only works on one USB port.
