If you have a forgotten/unknown device passcode, or have a disabled device, unfortunately you have no option but to erase the device. However, you can eventually restore the data and settings from a backup you made before the device was disabled. You must have a computer to use the method below. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider. You can also use a PC with iTunes. You will likely also need your Apple ID and password. All Apple mobile devices follow the same general procedure but the link below and other links off it provide model-specific instructions:

Here is a related video which to me has more complete and clearer instructions: https://www.youtube.com/watch?v=7s8-zLG9ySQ
Steps:
1. With the device disconnected from a computer use the model-specific instructions in the links above to shut down the device.
2. Connect it to a computer with Finder or iTunes (Mojave or earlier, or PC).
3. Restart into recovery mode (black screen with a cable indicating attach to computer).
4. When prompted, click "Restore" to erase data & settings, and update system software. May take some time.
5. Set up your device ( https://support.apple.com/kb/HT202033 ). Partway through you are offered the opportunity to restore your data and settings from a backup, or you can do this at a later stage ( https://support.apple.com/HT204184 ). Even if you have no backup, if you were using some iCloud services to sync items such as Contacts or Photos those may reappear once you sign back into your iCloud account --> Set up iCloud on your iPhone, iPad, or iPod touch - https://support.apple.com/HT208681
