Hello , I hope someone can help - going backwards. I have a raspberry pi 4. I was running an earlier version of venus OS on it. I did this by following Himmelburger bus. All good. Unfortunately - I became over confident and attempted to upgrade following his latest video. ie Venus OS . wic gz after some time I managed to get something on my pi 's screen but am not stuck. PS - I am a very green novice at this. Hope someone can help.
