Aside from gaming, video and music, I was able to install some apps which provided me with more features.But since I’m a bit newbie with updates, I never tried to modify or install a new firmware(note: I’m using a custom firmware for my PSP that’s why it’s risky to update compared with official firmware) and I had my first PSP pre-installed with custom firmware.But out of curiosity, I installed the latest version 3.90 M33-2 from dark-alex’s website and fortunately I successfully installed the firmware.
Hackers refused to apply updates which would render their hacks unusable so Sony attempted to convince users that there was a benefit to upgrading by including new features in the firmware updates, such as a web browser, and not just security patches to plug the vulnerabilities.Business Week dubbed this the "carrot-and-stick" approach. Users attempting to downgrade their PSP using this software instead found that is was rendered inoperable as this software deleted important system files.It will interfere with existing * XMB plugins that use HOME, so it can be disabled in recovery. Instructions are same as in previous release, except 3.30 * firmware did not have libpspvmc.prx, so just ignore that file.* Warning: There is an incompatibility between 3.30 savedata and later ones.some are simple, and some are complicated so I will post here a simplified direction in updating custom firmware: : A failed update may result to Crashing your PSP system making it bricked.
You are doing this at your own risk and I am not responsible for any loss or damage that may occur during the process.If you exit the browser, the firmware will still keep it in memory until you enter other area of xmb, until you do so, you will not be able to access vshmenu again either.* video isos and the game isos show in xmb use the same core.If a savedata exists from 3.40 , the emulator will freeze.A few notes from the M33 team about vshmenu and UMD video ISOs: * vshmenu cannot be loaded when the browser is active.Hackers and other homebrew enthusiasts then encountered the first trojan for the PSP. In Mid-2006, after several months of problems in defeating the PSP's firmware a file was posted online which allowed new PSPs running firmware version 2.6 to downgrade to 1.5 so they could then be hacked using older methods.
