Ipad will not start

This is because you have tried lots of time to unlock the device but failed,

but you can now solve this issue but you have to this if you know the id and password of your Apple ID if you have this then follow my Steps

1.Turn Off your iPhone, iPod touch, or iPad if it isn't off already.

1. Press and hold down the On/Off button on the right side (iPhone 6 or later) or top (all other iPhones, iPods, and iPads) for 3 seconds.
2. Swipe the slide to power off confirmation slider to the right.
3. Press and hold down the Home button on your iPhone, iPod touch, or iPhone.
4. Plug your iPhone, iPod touch, or iPad into your Mac or Windows PC and make sure iTunes is running.
5. Release the Home button when you see the Connect to iTunes scree
6. At this point, iTunes should display an alert saying it's detected an iPhone, iPod touch, or iPad in recovery mode, and will let you restore your device.
