Undo restore I accidently reseted my phone/ so I don't have anything. how do I undo that to get all my stuff back

Most of the time you cannot restore back to before you did a hard reset unless you backed up everything to an external device such as an sd card or to your computer. Unfortunately phones don't normally have restore points incase this happens :(

You cant, :(

no known ways because factory settings means permenant delete for files

You can use SkyDrive and upload your files:
SkyDrive.com

Actually The code *#7780# it's for restoring the setting in a soft way. (selecting 'settings only will reset all preference settings. Restoring will not delete any personal data. After restoring, the phone will restart)
where as *#7370# it's for hard way (lets you restore settings and delete personal data. You will not be able to use or switch off the phone during the restore, even for emergencies Restoring may take several minutes. After restoring, the phone will restart).


But there is no other means to recover the contact no.

Thanks for using FixYa.

Factory settings reset. In standby, dial *#7780# and the phone's lock code (the Nokia's default lock code is 12345). This reset restores phone's original settings.

Soft reset. In standby dial *#7370# and the phone's lock code.
Warning!Soft reset deletes all your phone's data, so backup your stuff before you do a soft reset!

ummm it would be very difficult to undo the changes without running a system restore, go to www.combofix.org, download combofix and run it. i can't guarantee it will fix the problem, but it's worth a shot

You don't have to reprogram anything with an ipod, the software are giving you problems, you can reset it back to factory settings(default settings) ie. "Restoring iPod to factory settings". All your data will be deleted upon reseting to default settings. Reference link from Apple

You can reset this phone by holding the CAMERA + GREEN CALL + RED buttons simultaneously while powering up the device. Once booted enter the security code "12345".
