Hi! I am sorry to hear that! We tested the PowerBlock with quite a few extension boards and that should not happen at all.
Please contact me via email or webform (https://www.petrockblock.com/contact/) so that we can arrange a replacement.
So, I have mounted the PowerBlock and I have tested it for some days. It works almost as expected, spordically it shows unexpected behaviour. I will create a separate thread explaining my observations.
Anyway, thanks for supplying me with a replacement device.
Edit: So as to what mitu and the others spoke of, I feel so dumb. Like I said earlier, I was able to boot into noobs just fine, and I had raspbian full installed at the same time as my retropie. I tried accessing the files for retropie that way earlier to see if I could recover my retropie or change configs or remove powerblock drivers, etc... But the issue I had was nothing showed up under the Raspbian desktop file manager earlier. I reinstalled everything after having lost it all earlier, and when I reset up my raspbian desktop just now, I got a link for retropie on the desktop. GO FIGURE, it only showed up after updating and rebooting raspbian desktop....
Since i rarely ever use the desktop os and mainly only ever use retropie, it didnt cross my mind to try updating and rebooting raspbian and see if I could access those files again. So to reiterate, as the others have mentioned if anyone ever stumbles across this and is in the boat I was in, if you're lucky enough to have raspbian installed as well as your retropi, you CAN access your retropie files and fix the mess as mitu said. Hopefully this saves someone else 6hrs+ of recovering lol.
