Respuesta a "How to fix iTunes error 9"All else has failed and you're feeling screwed, watch this video: https://www.youtube.com/watch?v=chZSdY5H... TLDR: Treat the phone just like a PC: 1. Open iPhone 2. Disconnect everything - A. Unscrew square-ish metal piece at the top right to get at the connections to the screen, back camera and volume buttons - B. Unscrew the long rectangle-ish metal piece next to the bottom right corner of the battery to get to the battery connection and lightning connector 3. Connect the battery and screen and see if it works 4. Connect the lightning connector to plug into iTunes 5. Plug in other connectors one at a time to see if they are causing the issue.
Respuesta a "Installed Yosemite, Mac since crashed & won't start up"I'm having this same issue. Unfortunately I don't think I'm resetting the SMC. Computer boots 10% of the time. Tried booting to Ubuntu on USB. Gives me a menu to install or try Ubuntu, after picking anything, screen goes blank. I tried putting Mavericks back on it and it froze during setup.
