I'm on Rogero cfw4.21 ver1. Most things working fine except Just Dance 4 black screens after intro vids! I'm not desparate to get on PSN so i'm in no rush to downgrade and then reflash to Rogero 4.30 and might be more updates different firmwares next few days the way things have been progressing. Saying that I have been preparing downloaded the 4.25 to 3.55 downgrade pup, Rogero 3.7 and ToggleQA.pkg. I have a question regarding QA flag I never did this on 3.55 so its not active on my system by the looks of it I can't run it on 4.21. Is anyone else in this situation I've never downgraded with flasher or done cex to dex so never really felt the need for QA Flag. What do you think is the best way forward just use the downgrder pup and then install Rogero 3.7 and then qa flag or do you think maybe I should wait and see if qatoggle can be resigned for 4.21 if that is possible/safe.
