This is a mod (hex edited) of the 6.60 Chronoswitch Downgrader by Davee/some1.
Qwickrazor87 only tested it on a 1k model, he couldn't downgrade to 6.60 from 6.61 (maybe corrupt updater), but I was able to downgrade to 5.00 from 6.61, 6.20+ might work, haven't tested it though.Download. 6.61 downgrader http://bit.ly/1xieDNm
