Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Do you have latest iTunes installed on your PC ?
You need to restore it by putting to DFU Mode. DFU Mode is a recovery mode which allow you to restore the software of iPad to working condition. Remember, restoring the iPad will erase everything from it and install a fresh software. But if you have backup, then you can restore that backup to your iPad after restoring the iPad
Follow the steps below to restore your iPad by putting it to DFU Mode.
First download and install latest iTunes on your computer from here : https://www.apple.com/itunes/download/
Then connect the iPad to your computer with the USB Cable.
Open iTunes application on your computer.
On your iPad press and hold the Home button and the Power button at the same time.
After EXACTLY 8 seconds release the Power button. Continue holding the home button until your iTunes shows a message telling you that it has detected an iPad in recovery mode.
Click OK or Restore
Note : Put it to DFU Mode while connected to computer and also in DFU Mode your iPad will remain blank and will be unresponsive. It is normal. If it is not showing blank/black screen, then repeat the steps again. Timing is critical when you put it to DFU Mode. So keep trying until it goes to DFU Mode. And it will take a while to restore it.
Remember, it may take a while to restore the iPad (the iOS firmware has to be downloaded, you will see the Download button at the top right corner of iTunes screen. Click it to see the time remaining)
Please let me know if that didn't work, so I will continue to help you until we fix the problem.
Did you try downloading the firmware manually and restoring it ?
Also did you try different USB cable a?
What about restoring from another computer ?
Can you disable the Anti Virus and try a restore ?
I'm really sorry. That points out an hardware issue with iPad. It might be port of iPad since it doesn't go beyond Waiting for iPad. You have to take it to the Apple Store.
