Thank you so much. I had the "gamecoin"-type brick on my o2ds. Using your instructions, I found the extdata was the issue. It was folder f000000b. You asked about this from OP and didn't get a response, so here you go.
Is anyone familiar with former forum opg.life ? I missed the transition to the new forum over the week end (was scuba diving in the sticks with no internet connection). If anyone in touch with any members please pm me.
