Hi all my raspberry Pi 4 was working, up until about a week ago was fine but then it stopped sending info to the VRM and I haven't been able to see anything on it since it was working 2.66 so I upgraded it but that's when I stopped seeing the Pi so I formatted the card thing that it maybe corrupted but still can't see it or connect to it via bluetooth. I have tried using Mac and pc but no luck do I have to get a new Pi? or do I have to do a factory reset on the Pi?
