On a 079 , you can reinstall original firmware Sony, because It has original idstorage key.
On a 082/6, the keys are broken by the downgrade process, so you can't reinstall newer 3.30->3.51 firmware, for brick risk.
So, does the 3.50 downgrader break the original idstorage keys, or is it safety?
Post 3.50 downgrade, can I reinstall the Sony firmware 3.30->3.51?
(I ask in order to inform myself. I want continue to use my excellent 3.40)
