Product: Hp elitbook 2560p
Operating System: Microsoft Windows 7 (64-bit)

Issue is i updated Bios to F.66A and it worked but i started getting serial number error so i looked on forums and saw alot of post hp tools and nbdmifit for serial edit.. i tried using nbdmifit 2.10 but problem didn't resolved so i tried all verisons... problem remains there. i cam across on different site and forum that on above F.50 bios you cannot edit your serial number as they are patched by Hp ... well i don't know is it true or no? now i want to know how to edit serial?? either on F.66a or by downgrading (although i tried downgrade it only downgraded to f.63a and after it said you cannot downgrade it didn't downgraded to f60a). can anybody help me how to fix serial number or how to diwngrade bios so i can fix this error?
