How to restore my iPhone without iTunes and it has a lock?

My little brother put a passcode on my iPhone last night and now i can't use it, i want to restore it or just remove the lock without iTunes cause i can't download iTunes on my laptop.

You can jailbreak your iphone but that wouldnt be recommended, but to do it safely you need itunes to restore your iphone, but first you need to back up your iphone on itunes so when it clears everything you still have your back up data to put it back in without the lock password best of luck!

reply to you. You can reinstall itunes and start over. Use a new email for the email you forgot. You might need a itunes card or a credit card number to do so
