Older IPSW restore file (backward restore) from Apple nowhere to be found
I tried downloading any of the iPod Touch 1G IPSW from these two sites:
http://www.hackint0sh.org/forum/f127/22056.htm
http://www.felixbruns.de/iPod/firmware/
But I get the following error after option-clicking Restore in iTunes and custom selecting the IPSW:
"The iPod "Name of iPod" could not be restored. An unkown error occured (20)."
And the iPod stays in disk mode until I reset it and reinstall the latest Apple IPSW version.
I did prevent Safari from extracting the so call ZIP masked as IPSW to keep the file intact for iTunes as recommended here: http://hackint0sh.org/forum/showthread.php?t=19008
Where can I find legit IPSW file from Apple?
Is it possible to go back from 2.0 to 1.0 restore?
Tks!
