I answers this question in another forum. Do number two on my list
t takes a little doing but Im happy with my setup.
1)
Download MPHDowngrader (Version 1.0.1) from
http://mphwebsite.tuxfamily.org/inde...rg=1&program=9
follow the instructions and downgrade your psp to 1.5 allowing you to homebrew. Dont let people try to tell you this will mess up your psp. It wont.
2)
Download
MPH Firmware launcher (Version 1.3.7) from
http://mphwebsite.tuxfamily.org/inde...g=1&program=14
this will let you BOOT not update your psp to play newer games. But the easiest way to get your ps running 2.5 is to PM me and ill send you the package with everything where it needs to be. This will allow you to boot 2.5 to play GTA and give you the web browser, but then u can go back to 1.5 and homebrew all you like.
3)
Get WAB Version Changer
This will trick your psp into thinking tis a different version. I semine to 7.50 so no UMD will update my psp for me.If you have trouble finding it with the 7.5 ill send it to you.
SO.... now your psp can run homebrew, wont be updated by a UMD, u can play all the newest games, have the ps web browser, and run homebrew.
PM ME!!!
