i downgraded my psp to 1.50 before i saw this thread, so can i upgrade it to 5.00 m33-4 directly or do i have to do something before aswell. Please tell all the steps i hav to do to upgrade it to 5.00 m33-4
If you are at 1.50 i believe you have to go through a process of upgrading through different cfw's (eg: 3.52 m33-3 > 390 m33 etc) if you download the cfw .rar files there will be a txt file telling you that you must have a certain cfw (or higher) installed on your psp to install that update. (for more detail feel free to pm me)
cfw can be found here >> <a href= "http://alek.dark-alex.org/filez/dax/">Link</a>
ofw can be found here >> <a href= "http://alek.dark-alex.org/filez/psp_fw/">Link</a>
if you dont wish to upgrade from one to the next and you have a spare battery (or the one you are using) you can follow the tutorial from the first post and just go to cfw 5.oo m33.
i hope this has helped you.
