Screen doesn't work after replacing volume flex cable

Hey,

I had to replace the volume flex cable, after that I check my phone if it works and connected the battery and powered it on. Works, good. Then I disconnected the battery to put the screws for the screen protection plate (the thing that protects the screen connectors on the logic board), reconnected the battery an now it doesn't show anything. I connected the phone to my computer and iTunes says it found a phone in recovery mode and I have to restore it to use it with iTunes. If I try to restore it im getting the 4014 error.

I tried to check the battery with a LED and the LED lighted up so I dunno what happened to my phone. I also ordered a new battery but it will take 4 days .

may someone could help me what i could do in the mine while, what i could check or something.

Sorry for the bad English .

Try rebooting the phone by holding power and home. After doing this, does anything show up? The recovery symbol or a red or blue screen?

OK. I was trying to rule out long screw damage which is what the poster below me was getting at. You did put the longer screw in the upper right spot?

If its not long screw damage, it could be as simple as a bad screen. Another possibility is a torn LCD flex cable or a damaged LCD connector on the logic board. I would examine those to see if you find any damage and possibly try a known working display.

One other thing: disconnect your battery, plug the display into the logic board, then reconnect the battery. Plug it into power and watch very closely to see if you see the apple but its very dim. Some people use a flashlight to help. Its possible that the display is working and that its just very dim, which would be a backlight filter blew.
