My GW emunand was on 10.3 but upgraded to 11. Once on 11 the method of using the select key to access the GW rom selecter no longer worked. The only way I could think of to get back to 10.3 was to format Emunand and use sysupdater. However after formatting emunand I can not install HBL on 4.5 as i get the following message
