No display even in the older crush lcd no light but it has a connection is there any bug in the version on ios 10.1.1 or...

first make sure you put it in dfu mode then try to download a 10.2.1 (5s GSM) iPhone_4.0_64bit_10.2.1_14D27_Restore.ipsw then if you get it restore manually hold shift down the press restore find where the file then go

your battery is totally drain or dead u must replace it a new one or try to shock it with the power supply in correct voltage

no that was the bug of ios 101.1. just update in itunes try in dfu mode....you can do it to in mannually remove the battery then connect again

just press the home botton 3 times fast the top it with two fingers

try to reconnect the display n light connector then put it in place proper in the dock connecting port then try not to close power it on then hold the assitive touch try to slide up and down all corner then if there no hold up or loosing it it was good or sometimes the lcd it self has no good so change it then try another one ps...disconnect the battery when you connect or disconnect the lcd flex so no static charge can damage the diode or capacitor

Try to test connection dock of the vabrator maybe it has a small shorted there or dirt if it not work try to the replace new one part

First check the imei on imei chechker site if it say find my iphone is ON you can restore it then you need the apple id of the previous owner then if it say OFF Just restore it no need activation process

Error 4014 network not stable reset ur connection then if it comes to error 3 that was the baseband ic u can reheat it or change but WARNING it can bring your unit totaly dead so just correct the error properly hope it help

Try to clean the ram or replace it...
