I have a Black iphone 5s which i tried jailbreaking back when i think ios 9.1 jailbreak came out n basically it all went tits up now its stuck on boot loop/ blue screen an has been since, tried restoring it but keep getting errors so just tried updating itunes but now my iphone is all black an wont even boot so i can’t keep trying, i have no clue.
Hold down the power button and wait till the device powers off. Turn it back on and see if this brings the device back to life. if not restore
