Just flashed and phone won't charge

[ragreenburg]

I just flashed my microSD last night and gave it a spin and after the tutorial I had 2 issues. The first being that after the tutorial I literally only had the spinning wheel as my home screen. So if I pulled down from the top I could see the task menu(?) but swiping left and right didn't do anything and pulling up from the bottom opened the camera. Secondly, it seems like it won't charge right now. Any work arounds for that? Also, should I just reflash my SD card since it seems like my install is a bit broken?

First issue, put a sim card in it. Doesnt have to be a working one.

Second issue, make sure you're running the latest kernel version. 

Okay, the first issue is fixed. How do I update to the latest kernel version?
