How you data wipe your device varies from operating system to operating system, and sometimes even device to device. These are general instructions that should work with most devices; however, it's best to check with your manual or manufacturer just to make sure.

For Android 4.0 or later, go to Settings and look for "Backup and reset." Tap that, and then, on the next screen, tap "Factory data reset." You'll get a warning screen along with a list of all the accounts you are currently signed into.

With iOS7 or later Apple introduced a new security measure called ’Activation Lock’, which is linked to ’Find my iPhone’. If the Activation Lock is still activated, the device will be locked to your iCloud account which is only accessible with your Apple ID and password.

With Android devices activation lock was introduced to prevent someone from activating your device should it be lost or stolen. On Android devices these locks can vary dependent on the device.

If activation lock is enabled on any device we are unable to test it or resell the device, we will be unable to access any of the functions and the device will become inoperable.

Please check this link on how to remove iCloud.

For Android devices – To turn off device protection, Click on settings – Accounts – Select Account – Tap More – Remove account – Please ensure all associated accounts are removed.
