Hits писал(а): This service is necessary for those who for some reason - lost the original contents of the EFI firmware chip (for example, as a result of incorrect password removal UEFI), the same way if you placement PCH on your board(Intel 82hm76/77/87 etс). It's fix troubleshoot - in ASD "XXX firmware corrupt", slow loading OS, hangs at OS boot time, slow work in the operating system ( stroboscopic effect when page swipe in the OS), the correct EFI unlock. I got a liquid damaged 820-3209-A board with management engine missing... plus some temp sensors failing. I bought the laptop this way and to my knowledge no password removal had been done. How can I find out if my firmware is really corrupt? Can you see this if I send you the original bin file? |

Could you please check my bios in thread "MacBook: BIOS dump" if its really broken and at least management engine will work again after your modification? |

Management engine is back again after flashing clean bios... but ASD reports serial number format is not correct and temp sensors still failing, fans on high. Could it still be the bios or definitely something wrong with sensors / smc? |
