Q: iphone 5s get stuck in verifying update

Hello ty_grafix,

Thank you for using Apple Support Communities. It's my understanding your iPhone has become stuck verifying the software update. I can surely understand your concern as you're unable to use your phone at this time. I am happy to help.
 

First, I recommend force restarting your iPhone. Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo. 

If you can’t update wirelessly on your iOS device, you can update manually using iTunes on a computer that you trust. If your computer is using Personal Hotspot on the iOS device that you’re updating, connect your computer to a different Wi-Fi or Ethernet network before you update.

1. Install the latest version of iTunes on your computer.
2. Connect your device to your computer.
3. Open iTunes and select your device.
4. Click Summary, then click Check for Update. 
   
5. Click Download and Update.
6. If asked, enter your passcode. If you don't know your passcode, learn what to do.

If you see error messages in iTunes or need more space to update

Get help if you see error messages while updating your device with iTunes. Or if you need more space for an update, you can delete content from your device manually.

Update the iOS software on your iPhone, iPad, or iPod touch
