Help me bypass the activation lock on my iphone 5s (ios 11)?

An activation lock happens when Find My iPhone is enabled and you've tried to restore the device or it has been reported lost/stolen.

As this is a theft prevention feature, it can't just be bypassed like that. You need to enter your Apple email and password to unlock the device. If it isn't your device then there's nothing you can do, you're either a thief or you were scammed.

The phone belonged to my brother's friend and he forgot his password. So i'm doomed?
