So a few days ago I opened up my phone to replace my busted silent switch. The switch repair went well and the switch is fixed. the problem is that at some point in the repair something went wrong. Now when I plug my phone into either the computer or charger the battery screen doesn't come up and it doesn't show up on my computer. It still charges but I cannot sync it or easily track the progress of its charge.

I tried replacing the dock connector assembly with a brand new one but still have the same problem. What else can it be?

- Thanks
