1. download the easy installer:
INSTALLER

2. extract archive.
You will get these files....
2.71_TA-082_-_1.50.exe
README_DE
README_ENG_ORIGINAL_DARK_ALEX
TA-082_Downgrader.pngfile.
3. format Memory Stick and restore the psp to defualt settings.
4.run the installer and it will install everything on to your MS including HEND.
5. When it's done installing Start the psp and go to pictures and load HEND ---> IT MAY NOT load the first time so restart and try again. Make sure you have no UMD inserted when doing this!
6. Once its loaded (the psp will restart automaticly --> this means it loaded HEND) go to GAME in the XMB and load/start idstoragechange.
(this program just changes some keys ^^)
7. Once this program is done and loads your XMB again, go back to the GAME menu an you will see your Generic downgrader called "Update X.YX"
Load/start this.
8.This will now install the 1.5 FW onto your psp. when its done it should ask you to press "x" were it will restart the psp an you will get a error.
Simple press "o"
If you get a black screen on restart and can hear the sound hit the black light button on the psp it should resolve the problem
Enter your information and voila, 1.5 FW!
