Hello guys,
I've been learning about computer repairs and got a MacBook Pro A1989 that had some liquid damage. After thorough cleaning, the board was getting 20V and 1A+ when the battery was connected but the laptop still wasn't booting. The symptoms were similar to another thread I found here (https://www.badcaps.net/forum/showth...hlight=20V+amp) so I followed the advice of entering DFU mode and was able to recover the firmware and it is now booting (the revive option was giving me an error, so I had to erase everything).
However, I've been unable to install macOS on it. I tried internet recovery but get a message "Security Settings do not allow this Mac to use an external startup disk" after it reboots. Reinstalling macOS from the macOS utilities gives me an error saying "the recovery server could not be contacted".
Sorry in advance for being a noob, but I'm still learning. Hopefully someone in here can help me fix this issue.
