Recently i updated by PS VITA with official firmware update (1.61) from Sony. I was not at all impressed by the features offered by Sony with this new firmware update, and at the same time it was causing freezing and other irrtating issues.
So i decide to downgrade my PS VITA from firmware update 1.61 to 1.60. As i started the downgrade process i got an error "C1-6562-9" with just this line as description "downgrade failed".
Everytime i restart the downgrade process i get this error. Please help.

how did you start the downgrading process
