Passcode recovery

If you did not write down important things.....like your passcode.....you must now reset/erase the phone and then set it up all over again.

If your iPhone is running iOS 15.2 or higher........you can use the instructions linked just below:

If your iPhone is not running iOS 15.2 or higher, or the instructions above are not working.......please use the instructions linked below, but note that you must use a PC or Mac.

If you have a backup of the phone, you can use the backup to restore the data on the phone during the new setup.

I’m glad you fixed it. And now you know that if you ever forget it or enter the wrong passcode too many times that there is no way to recover any data on the phone that you haven’t backed up. As there are many ways to back up content on your phone, use at least one of them (such as automatic nightly backup)→How to back up your iPhone, iPad, and iPod touch - Apple Support

i already fix the problem...i already remember my passcode...

Excellent. I would recommend that you write down the passcode and keep it in a safe place......even though you might feel that you will never forget it.
