Ezb V4 Is Broken, Please Help

(shortly before this the speaker stopped working) A short while ago i was working on a project and i unplugged the ezb v4 to fix a mechanical problem with my robot and when i plugged it back in after, it would connect to the laptop's wifi but it couldn't connect within ez-builder. The lights still work and when i go to the page where you change the type of connection it blinks the correct colors and looks like it is working (with the exception of the speaker). I don't know what to do and would appreciate some help, Thanks.

Sounds like the main arm processor on the bottom board of the v4 has been damaged. The ezb will need to be replaced. Please post a schematic wiring diagram for your robot so we can help prevent this from happening again. You will need to provide a schematic of how you are connecting your robot and what you are working to achieve. Also provide what power source you are using and how it is configured.
it was a while ago and I don't remember what robot it was, however I do remember what battery and I can get all the details once I get home

Ps-i am the one that makes the paper straw robots
I think I was using a LiPo battery and the robot was a bipedal robot modelled after a human but it didn't have a torso, the legs were too close together so I took the v4 off (without unplugging the servos), took the legs off and reattached them farther apart, then when I started it up it wouldn't connect. It did not get dropped or anything while I was working on it
Actually I was using a hi rate lithium polymer rechargeable battery, 2200 mAh, either 11.1 or 14.8 volts
