Hi all !

I'm on Rebug 3.41.3 and i want to upgrade to rebug 3.55.2 to play some game can not play on 3.41. Do i need replace the HDD with new HDD to install new CFW ? Because if i want go back to 3.41 all data on old HDD will not erase after downgrade. And i only put the old HDD back and my game working again. And the best way to downgrade is use QA token flag or use dongle ?

And the old HDD still play game if i put it back to PS3 had upgraded to rebug 3.55.2 ? Or PS3 did not recognize it and force me have to reformat ?

Thanks for any helps.
