Can you explain this part a bit better:
i decided today to update my slim from 3.41 jb(with ti-84) to rebug 3.55.2. so i read up and most guides say to go to 3.55ofw first(got here from ps3hax). okay so i tried but got a copy error. i figured it was a file permissions thing so i installed multiman(cuz i think it has a built in fixer). so now the install works and i am on ofw 3.55.
I don't understand what MM has to do with installing the FW...
(you installed the 3.55 FW from 3.41 XMB?)
