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 ?
It has nothing to do that hey are real corrupted. It's more the ps3 doesn't find the correct system files on hdd for your installed FW. There for it tells you that the files are corrupted. If you reinstall the system files which the ps3 will do automatically all your previous files will be still there. It's no format task just a reinstall files task.
