where are you getting the eboots?

if you are getting the 6.60 eboot from sony then the download might have corrupted.if each download you try fails try updating through a UMD if you have any above 5.70

Restored default settings, change OFW updaters ,i even update thru wifi (SYSTEM UPDATE)

I even Tried UMD with 6.60 updater
