Going back to your original post
I see that you are trying to resurrect a bricked Printrboard by using an ISP programmer. There are very few people in this forum who have experience doing that, and perhaps none are actively looking at the forum these days (traffic here has slowed down a lot in the last 6 months). When you post a question but get no answer at all it probably means no one who read your post feels qualified to answer.
I had a Rev D board that went flaky (all on its own, not because I was trying to re-flash it), and I bought the ISP programmer and tried to use AVRDude to fix it, but I was not successful. I don't know for sure if my technique was wrong or if the board was truly unrecoverable, but I ended up getting a new Rev F board.
BTW, if you do decide to get a new board, I'd recommend the F6 over the G. I'm afraid that the G board will require the latest cloud-based software, which at last report is still pretty buggy.
