I was running enigma from the 4th Dec and today Software update reported there were 303 updates ,so i tried to update.Firstly the shutdown problem is back again,which I overcame by issuing
chmod -x /usr/bin/turnoff_power in telnet.
After doing this the update did indeed continue and complete,but upon reboot enigma2 doesnt start and the image just remains on the initial boot screen.
This is on a VU+ Solo
