Sansa Fuze Firmware Update version 01.01.22 & 02.01.17

Can the update be removed?  My 8GB Fuze had the original settings, and then I updated to 01.01.22A using the firmware updater application.  I don’t like it.  I preferred the scroll stopping when coming to the end of a list, the Recently Added section listing all the songs, and I think the radio’s sensitivity to picking up frequencies has worsened (many more stations are staticky).  The Play Previous is the only decent feature, in my opinion, and that’s not worth all the downsides.
