My iPhone 4 vibrator and volume buttons are not working after taking phone apart?

I took my phone apart to try to repair my home button. I followed all of the steps correctly on https://www.ifixit.com/...ement/3144
Now that I have put the phone together, there's no vibration and the volume up and down buttons and the silent switch are not responsive.
Any ideas?

Hi yes take it to someone who does know what they are doing. These self help videos are not telling the whole story.

"I followed all of the steps correctly…"

No you didn't. If you did the phone would still work - unless the instructions are wrong!

Take it to a repair shop or repeat your DIY "repair"

  • Volume buttons not working iPhone 4S? So basically there's a problem with my phone where the volume buttons won't work, bu this I mean that I can't watch videos or listen to music without my earphones. It happens almost everyday at a particular time and just happens suddenly… Anyone have any ideas why this is happening?
  • Vibrator function not working iPhone 4S? Hi… I replaced my friends LCD on an iPhone 4S and after the repair the vibrator is not working. Anything wrong I probably did? I've been doing this for a while and never had a problem. Everything works but the vibrator function.
  • One of the volume buttons on my iphone 5 has stopped working? The button to raise the volume doesn't work, but the button the lower the volume works just fine. How can I fix this?
  • My volume buttons do not work on my NEW iPhone 5s, can you relate? Or tell me why? So I just bought my new phone, about 3 weeks ago. No problems what so ever just recently I think it started last week where I couldn't volume up my device, the volume down button worked. But no matter how many times I'd press volume up it wouldn't work. Just click click click, nothing else! I've been swiping up the screen like where you can increase the volume from that but it's getting annoying this is a new phone! It should work perfectly.
