This A1708 came in totally dead with liquid damage. The wifi chip had been on fire so I pulled it and cleaned the area. After that it starts but obviously wifi is not working at the moment. And it...
I’ve used this method with success already many times. But now I got a case where customer is using Windows Bootcamp. After the GPU replacement the computer hangs in boot loader immediately after choosing the Windows partition to boot. A Google search let me know it is because of the edited...
We see a lot of customers these days that have got their Apple ID hacked and the hackers locked their computer and asking for money to unlock it. We only help them if they can prove they are the rightful owners.
I also get these ones in regularly. I stopped posting about the issue about a year ago after a couple of threads in here with no solution to the problem. Please make a sticky about it if a common issue with a solution is found some day...

Wifi rarely work in boot menu and I can press the hard drive icon and it boots up with wifi working. But mostly no...
