HEY SORRY GUYS I CANT GET IT TO WORK WILL ANYONE HELP THIS LIL GIRL?

OK SO I READ " THE Downgrader_HOWTO"

Here are the steps to downgrade any 3.50 PSP to 1.50:

1 - If you have a 3.50 PSP skip to step 6

2 - Download 3.50 update from here:
http://dl.qj.net/PSP-Firmware-3.50-(...3840/catid/163

3 - Unzip and place the file in <pspdrive>:/PSP/GAME/UPDATE

4 - On the PSP, run the 3.50 update from the memory stick under the Game menu.

5 - Delete <pspdrive>:/PSP/GAME/UPDATE

6 - Copy the contents of the folder MS_ROOT from the 3.50 downgrader ZIP to
the memory stick

7 - Unzip the 1.50 update to a temporary folder. Rename the EBOOT.PBP to
UPDATE.PBP and copy it to <pspdrive>:/PSP/GAME/UPDATE/ . DO NOT
OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP!

8 - Load Lumines and press x to start the game

9 - The screen will clear to black and fill with a light blue colour, then
the PSP will reset itself

10 - Check that HEN is running by going to system settings, then to
"System Information" and it should show up as system version
350 HEN

11 - If it is showing up as HEN then go to the memory stick and
run the x.yz update

12 - If you have an unpatched TA-082 or higher motherboard, you will be
prompted to allow the downgrader to patch your motherboard so it
can be safely downgraded. The downgrader will not let you proceed
without patching, if your motherboard requires it.

13 - Before the downgrader does anything to your PSP it will ask
for you to agree to what it is doing, if you no longer want to
continue press the Right Shoulder Button (R-TRIGGER).

14 - Once you have agreed to start the downgrade do not unplug the
PSP, or try and restart it

15 - Once finished the PSP will ask you to press X, and reset itself

16 - If it comes up saying that the settings are corrupt, press x
to continue, this will mean you will need to re-enter the
settings for network connections into your PSP, otherwise go to
step 18

17 - Load the included NetConfigBackup application in your PSP, and select to
restore, this will take the backup that was done of the network config
that was done automatically during the downgrade.

18 - All done now :-) Hopefully you now have a 1.50 PSP. Enjoy it responsibly.

I downgraded very easy without any problems.
you just need the 1.50 eboot and lumines I think
its the best downgrader.
