Updating 6.10 beta to 6.02?

[CrimsonFalzar]

So, I just got the update for 6.02 and I’m currently on 6.10 beta and I know if you go back on an update it fucks up with your external. If I update to 6.02 will that fuck up with my external ? ? also will my changed name still stay the same so many questions with the weird way Sony did this lmfao.

Was on 6.10 beta program too, rolling back to 6.02 couple hours earlier, all games on my 2TB external HDD work just fine. No bs like before  

Heard (some?) old betas had this problem (kinda certification/license issue, ext wont read because it's tied to newer beta version than current official system software )

Only happened to me once 'cause I don't usually go back from beta to official until the beta is over.
