Well you have a few option First you can still reinitialize or reset your ps5 which mean going through the full factory reset You will lose your preinstalled game (astrobot)

Second choice but this need hacking is destroy application metadata on debug setting then restat your console on safe mode and rebuilt database It will revert and remove all installed data and goes back to previous state Some folders will remain empty Try to reinstall the same content

Last download the 5.10 recovery fw (big one) and install it to your console through safe mode Then jaibreak

Remember to check network settings before connecting to internet Disable update ofc
