I did the steps that you suggested here, and at the beginning the camera worked for a while, but to the end of the day it gave the same error. So the next day I put some more paper, because I thought that the paper did not push enough the connector. Same: worked for a while then stopped. Also, it started to give me a green screen once, then the error again.
I also read the "charging cable" idea, I tried to find out whether the cable causes the camera problem or not, but I could not figure it out.
For some days the camera does not work at all.
Do you have some idea what I could do wrong or what I shoud do differently to make it work?
Thank you for your reply in advance.
