Q: I changed date to January 1st of 1970 and I restarted it but it does not work, what can I do to fix it?

Why would you change the date to 1970?

Your iPhone is a brick now. You can try using the DFU mode, even though there's no guarantee it will work.

If you changed the date to May 1970 or earlier and can’t restart your iPhone, iPad, or iPod touch - Apple Support

Contact Apple support and ask for help.

I do not need to answer: there are enough threads here about this.

It was clear from the beginning and published enough that this would destroy your iPhone.

The quick solution is to go to any trusted professional and have them disconnect the battery and then reconnect it.  This will reset the date/time.

DIsclaimer--it is possible that opening your phone may void your future option to have warranty service on your iPhone.

A DFU restore will usually recover the phone:

• Install the latest version of iTunes on your computer if it isn't there already ( (you must have Windows 7 or later or OS X 10.8.5 or later)
• Reboot your computer
• Disable any antivirus and firewalls
• Launch iTunes
• Connect the device cable to a USB port on the computer (not to a USB hub), but DO NOT CONNECT TO THE DEVICE YET
• Press and hold the HOME and SLEEP buttons at the same time for exactly 10 seconds, until the screen turns black, then release the SLEEP button but continue holding the HOME button. If an Apple logo appears while holding both buttons you held for too long; start over.
• While still holding the HOME button connect the other end of the cable to the device
• You should see a message in iTunes saying a phone in Recovery mode has been detected (it may take up to a minute for the message to appear). When you see that message release the HOME button and the device should restore. When asked DO NOT restore a backup; set up as a new phone.

Try several times if it doesn't work the first time; getting it into DFU mode is tricky.

Apple Support Communities contributor Lawrence Finch posted this User Tip regarding that subject: I set my iOS device to January 1, 1970...

See if that works for you.

John, that is the same as Philly_Phan explained....

Yeah, but Lawrence's UT is more interesting reading! - especially the parts about 'how tricky it is' to do 'just right'

yeah, well...
