What is the free imei unlock codes for a forgotten passcode?

I would just take it to a instore mobile phone repair man/or lady usually chinese are great at what they do not expensive .

For unlocking you need unlock code from imei number. there are many apps and software which generate unlock code for free. here is how to unlock iphone ipad which is locked disabled due to wrong passcode entered.

Below is procedure for unlocking iphone ipad.
First try to recover your password for that connect your ipod to computer via usb cable.
Now ipod is recognize by computer and find the folder named ipod. Now browse ipod folder and open ipod_control folder , inside that folder there is ipod _unlock file. Try to edit that file with some software to recover your password inside that file otherwise. Delete or rename that file and power of your ipod and restart it. There is other way to recover password but when I put such answer my answer marked as spam and deleted and some senior member using that answer method for their answer and get reputation.
Ipod got disabled when you have entered wrong passcode many times. And to unlock this passcode either recover your passcode from ipod or restore your ipod via ituens.
For that connect ipod to computer and if ipod is recognized by computer then open itunes click on device tab then summary tab on right side pane you will find restore ipod.Click on Restore iphone and ipod will be restored but this will erase all data on ipod.
If you don't want to delete data then there is option to restore ipod from backup. So restore ipod from recent backup. For that open itunes - click on devices and right click on ipod there you will find option restore from backup.
If none of above method can solve your problem then enter into dfu or recovery mode. For that connect your ipod via usb cable to computer and thenPower off your ipod, now press and hold power button and home button for 15 seconds, now release power buttonbut keep holding home button now itunes will detect ipod in recovery mode now restore your ipod.

iOS Forgotten passcode or device disabled after entering wrong passcode

Interesting question, I looed it up because my memory is so bad I'm likely to forget mine! I only pass coded it to keep the grandkids off it!

See link for instructions from Apple iOS Forgotten passcode or device disabled after entering wrong passcode

If you enter the wrong password six times in a row, you will be locked out forever, but you can follow these steps in this Apple article to restore your iPad. This is a security feature to keep sensitive data out of the wrong hands.


iOS Forgotten passcode or device disabled after entering wrong passcode

Hi John,

If you cannot remember your lock code, you will need to restore your device as new or be able to restore a backup if you cannot remember your lock code.

If you do remember your lock code you can update it in the settings app:

Click on Settings and then scroll down to the Passcode option (you may have to scroll down a bit). This will bring you to the Passcode Lock menu where you can turn off or update your lock code.

Hope that helps!

After you put in the wrong pass code 3 times, you only can unlock the iPad with the correct password, belonging to the Apple ID from what is only a part shown on the screen. If you don't have the passcode nor the password Apple assumes you are not the legal owner, and you can't use the iPad anymore. Just go back to your friend, ask him to unlock the screen, to wipe the content and reset the iPad to factory settings.
For that goto settings, general and scroll to the bottom line and press that. then the second line wipe everything. Again the login code is asked. but after that the iPad is empty.Your friend should also remove the iPad from his list of registered Apple equipment.

Unfortunately, you're a bit stuck. The only way of removing a passcode without knowing it is to restore from an iPad backup when the passcode wasn't applied.
My advice would be to take it to an Apple Store, and explain the situation. They're always very helpful, and may be able to do something about it.
Hope that helped!
