How to use stand alone restore file, iPod4,1_5.0_9A334_Restore. No *.ipsw file in folders.

Question

One of our Ipod Touch 4g presented with an "unable to sync" error a few days ago.  I worked around it by deleting the songs, adding them to a playlist in the library, then re-syncing.  That worked for a few days.  Then even that wouldn't work.  It wanted to update to ios5 so I began that process.  After erasing everything, the update failed (multiple times, several different errors, usually 1602 and 1604).  I've tried multiple cables, two different computers, creating a new user profile, new clear itunes library, all USB ports).  I've downloaded the update software inside of itunes at least three times.  I've downloaded it outside of itunes which is the folder "iPod4,1_5.0_9A334_Restore" however it doesn't seem to have the required file that ends with *.ipsw.  The particular ipod in question was jailbroken at one time, however it had been reverted to Apple with the last OS on it was of the 4 variety (4.3.2 maybe).  Also note that I have two other ipod touch, one of which is updated to ios 5.0.1, and they work with both of my computers, regardless of which USB port I use, or cable, so I'm confident its not a problem with my computer hardware.  I've also tried the update with the touch in DFU mode and still no success.  Anyone have any suggestions?  Thanks!

Basically you are asking as how to port silverlight to Xaml (RT). Go one by one converting each API from silverlight to XAML, like IsolatedStorage isn't there in RT, so look for its alternative etc.
See here the namespace/class mappings : Windows Phone Silverlight to Windows Runtime namespace and class mappings
