        Your backup is corrupt,its less that 1MB compressed,if you look at the code with a hex editor you`ll see its mostly empty, all FF`s ,compare it to another bios youll see a lot more code. Your backup was corrupt for a reason.. ,try another chip.

                                                        You can use the bios at post #31 ,but you will need to copy the new "Vimbai ORIG MBA" serial number into it. See post #20 for info

                                                                                    My repair guy has checked all possible. It's all ok with power. The last idea - I could kill EFI firmware... So, I need a firmware of EFI to check it. I have a programmer. But I don't have a similar laptop now to download it and compare

                                                                                    P.S. If you have else any ideas about repair, or you had a similar...

                                                                                    I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.

                                                                                    I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.

                                                                                    ...

I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD. I've flashed a ton of bios but still same problem. Windows installation works with this Macbook but never a mac installation. Unfortunately, since I didn't receive this macbook with a bios chip, I don't have the original bios. What can I do now?...

                                                                                    I have a MacBook Air that was completely dead on arrival. During inspection I found a shorted capacitor near the SMC, which appeared to be the main fault. After replacing the capacitor, the short on the rail was cleared. The board then started recognizing the charger, charging normally, and the machine powered on. Initial testing outside the chassis showed normal behaviour.

                                                                                    However, after full reassembly a new issue appeared. There is no boot chime and no image on the screen, only the fan spins. The power button responds normally, it powers on without the charger connected...
