Hi found a brand new GH1 with serial number WE09...
The shop doesn't permit to me to check the firmware version through the temporay service menu.
Is it sufficient checking the firmware version via the plain SETUP menu > Version DISP?
Yes if it's lower than 1.3 (what should be the case if it's new, and from 2009). The only "chance" it's not hackable would be it has been sold recently, broken, sent to repair, returned, and returned to the shop...
