Hello community! I would just like to inform everybody of my success in updating to Rebug's 4.21.1 firmware! I was previously on Rogero 4.21 v1.09 and all I did was install Rebug through the System Update menu on the XMB. I did not downgrade or anything. The only possible point of significance may be that I did enable QA while I was on Rebug's 3.55.2, however I did no such things before updating this time. I just wanted this to be in a thread on the forum as I know people will be looking for such information.
