iPhone won't open after exit recovery mode
Hello,
My iPhone turned off suddenly when i using it. And when i tried to open it didn't open. So i plugged in to my computer and tried to restore and update. I downloaded iOS 10.3.3 and tried to update phone. But it's unpacking the package and saying "Waiting for iPhone". After that apple logo opens up with a circular progressbar. But it's not turning. So i researched a bit. I found a software named ReiBoot. I've installed ReiBoot and clicked "Exit Reboot Mode" button. After that phone got restarted and stucked at apple logo. There's nothing on the screen but the apple logo. And when i plugged in to computer nothing happens. I tried to hard-reset (pressing power and home buttons for 10 second) but nothing happened. So I plugged out the battery and turned off the phone. Power button not working. I open phone with plugging cable. What can i do now?
