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?
When you say formatted the card, you formatted and then reinstalled venus os yes?
Does the pi appear to boot/you can see lights on it. What do you see if you plug it into monitor during boot process?
You are probably probably already aware, but it needs reimageing from v2.66 to v3.31 not just using an update file, it's unclear which you did, but:

Please connect a serial console and see what is happening during boot. Post the boot sequence here and we can see what is causing you issues.
