Introduction:
Hello! Not sure if this is the right thread but here is the tutorial on how to hack your PSP Street!
Not sure if it works on the 1000,2000 and 3000 models but all I know is that this works on the PSP Street Models (PSP E1000, E1001, E1002, E1003, E1004, etc).

BEFORE YOU START:
Make sure that your PSP version is on 6.60! I'm not sure if it'll work on 6.61 but I don't recommend hacking your PSP Street at version 6.61!
DO IT AT YOUR OWN RISK! It ain't my fault if your broke your PSP!

How to hack your PSP Street Model (PSP E1000, E1001, E1002, E1003, E1004, etc)

What you need:

• Your PSP
• A Mini USB Cable
• A PC (Computer, Laptop, anything that works for you)

Getting your files sorted:

1. Download the attached file "psp.rar" (down below).
2. Extract the "psp.rar" file (this should give you 2 files called "launcher" and "installer").
3. Copy the 2 files that you just extracted.
4. Turn on your PSP, plug the Mini USB to the PC, connect your PSP to the computer and make sure that it is on USB Mode.
5. Now, paste the "launcher" and the "installer" files in the GAME folder (the GAME folder is in your PSP folder)

The "Hacking" part:

1. Disconnect your PSP and go to "Game".
2. Scroll down to Memory stick.
3. Click "LME Installer for 6.60"
4. Once the Installer pops up, it'll tell you to click X, so do that.
5. Your PSP should restart after it installs some stuff into your PSP.
6. Now, go to "Game", scroll down to Memory stick and click on "LME Launcher for 6.60".
7. Just wait for it.....
8. That's all you gotta do! Your PSP is now hacked! You can now download PSP games for free and do whatever you want with it!

Conclusion:
Hope this works and that it helped you hacked your PSP Street! Just to let you know as well that this is not a permanent mod and that you'll have to go the "LME Launcher for 6.60" every time you have turned off your PSP! But it should take you around a couple of seconds, nothing too long.
If your PSP is on sleep mode, you will not have to go to the launcher every time.

That's all for now!
