After replacing the MB on the HP 250 G6 notebook CND8115JPR, system board 832E. I managed to change with BCU 4.0.33.1 (sp143621) the "product name" and "product serial number" but I can't to change the "product number". Product number is 2SX62EA#BED but whatever I do I always get "product information is not valid" on reboot. And always appears at the end of the SKU product number for 2SX62EAº special character(º) which is incorrect. BIOS is latest available F77 with InsydeH2O rev 5.0. CTRL+A isn't working for Advanced tab with this 250 G6. I also tried with EEPROM Utility v3.8.0. (HPBC380.EXE) from USB FreeDOS but I can't change the SKU also with this tool.
Has anyone else had similar problems and knows the solution?
Thank you in advance, Dan
