Hi I have Dell Latitude E7240 and i replaced mainboard. Thie BIOS version of new mainboard is A05. Now service tag form new mainboard is different with printed on case. I tried to change it but every software I tried doesn't work. Do You know which software I can use to change the service tag? If software change is impossible I have EPROM programmer and can desolder, read, program and solder W25Q64FVSSIQ and W25Q32FVSSIQ chip.
