Powers on everything, keyboard types LCD works, all functions there, however it gets to OS progress bar and then hits error support code -9000F (which is easily fixed with DFU reset) . Thought it was the keyboard so orderered a new on, tested that board on a good board and it went into DFU, so put the keyboard back into this board and no luck. Tested power button, it turns it off and on no issue, what could be causing this board to not go into DFU whatsoever? Battery is good as well. This is new to me and was wondering if anyone has a solution, the board is not activation lock, it just needs to get DFU restored to get rid of the -9000F support error to get into OS install.

Hey mon2 how are you? So this does not explain the DFU issue. This error -9000F can be easily fixed with a DFU restore. There is no data on this computer and needs to get restored to fix this error. Our wifi is good as well. Sadly it wont get into DFU.sigpic
MEOWING IN THE IMPOSSIBLE UNIVERSE!

Originally posted by Stephen View PostI believe we found the issue. Controller chip was not allowing communication between the USB cables besides charging. Will keep you posted.
Was going to suggest the T2 ROM, but sounds like you got it resolved!
