Paul recently bought an iPhone and the passcode has suddenly stopped working. Leo says that a full restore can solve the issue. He can connect it to a computer and then go into iTunes. But he may need to go into something called "DFU mode." This is a more serious reset of the phone. Paul should search YouTube for DFU and see how it's done.
William and his Dad built their own computer together. Leo says that's a great project to do together! But his hard drive crashed. He rebooted it and now he can't do anything with the OS. Leo says that it's best to wait. Don't reset because that'll cause the hard drive to spew data across the disk. That could cause the hard drive to become corrupt. Fortunately, William has a backup. So Leo recommends doing a deep, low level format and reinstall Windows. He could try running SpinRite, but that won't solve the corruption of the file system.
Eleanor has a 1st generation iPad and she doesn't use it for anything other than email and browsing the web. But Safari is constantly crashing on her. Leo says that since it's over 4 years old now, it's a good idea to just start over. She should sync it up to iTunes, back up and then restore it. But it may be that today's websites are just too hard on its limited power and memory. It's worth trying the reset, though.
Diane thought it would be a good idea to get an Android tablet along with her Android phone. So she bought a Google Nexus 7. She reset the tablet and now she has a black screen and she can't turn it off or get a live screen. Leo says that tablets are like any other computer and they can freeze up or crash. Leo recommends turning off the phone first. Once it turns off, let it sit for a bit and turn it back on.
John has a disabled and inactive YouTube account. He can't get it back up and running and contacting Google is no help. Leo says there's no magic with Google. They want him to tie in all his accounts under a gmail account and if it's inactive, he just needs to talk to them to get it back up. The easiest thing would be to start over, though.
