How to Downgrade PSP homebrew and perform all
With the latest versions of Sony PSP firmware 2.0 + introduced (new safeguards against unauthorized users with the software UMD known as "homebrew known). Lots of new PSP owners give when it tries to emulate their favorite old Game Boy or NES games on their PSP running with a new firmware version to get. However, there are ways around this. The most commonly used is the version of PSP firmware 1.50 – the latest official firmware versionNot to limit UMD unofficial. The problem is that it does not work on the declassification of all versions of firmware. Locate the firmware version as follows: you start your PSP to the XMB (Cross Media Bar, the home menu) and scroll all the way left to "Settings" column. From there, go to "System Settings" and "System Information". "System Software" is synonymous with the firmware.
Here is your basic approach depending on the firmware, youon your PSP:
1.5 Celebrate! You are in luck! Are you able to homebrew will run immediately.

Another thing to consider is whether you have a specific version of the motherboard) (only about 1% of PSP, where the process of downgrading the PSP does not work anymore. To test the motherboard, looks up
the printed circuit board for a while ' "IC1003" in letters of gold. If you do not see, you're good.
The basic procedure (for the 2.0 -> 1.5 downgrade) is calledfollows:
0) to disable anti-virus software on your PC.
Enter number 1) file specially formatted and the root folder of photos of the PSP. Check out http://www.downgradepsp.org for files and detailed instructions.
2) This leads to a buffer overflow in the image viewer, access to the PSP firmware.
3) Connect the PSP in an AC adapter. Start up PSP. Scroll to the photo menu. X Click and try to scroll down. One of two things happen:PSP meets a black screen with white letters and numbers, or your
PSP freeze.
4) If the PSP freezes, just start new and try again. When you hit the black screen with white text, do a hard reset (Hold switch to 10 seconds) and reboot.
5) With the AC adapter connected, scroll right and access to your memory stick under GAME
6) upgrade 1.5 U.S.
7) The update is running and not necessarily 99%
Restart the PSP,and you hit the PSP blue screen of death.
9) No problem, hit "O" and you're done!
If everything went well you should see the 1.50 firmware-logo for the next reboot and have the ability to run any homebrew now! This ROM includes emulators of other consoles like the Game Boy, NES, and many others,
Film and game backups, and self-written programs. Be a good comparison of the sources of software for PSP homebrew http://www.pspgoldmine.com found.
A wordBe careful – tampering with the PSP as described above is risky and not authorized by Sony. When things go wrong, you can end up with a screwed-up on the PSP, which will not run. To prevent this from happening,
