Updating from SE-A to SE-B
--------------------------

- Copy the directories seb_update from SEB_UPDATE/PSP/GAME150 to /PSP/GAME150/.

- Run it. After you press X, the update will be done in a little moment. You are now in SE-B.


The following two sections are for a installation from zero:



Creating the DXAR file
----------------------

-Go to NEWINSTALL/PSP/GAME in 2.71 SE B folder copy seupdmaker and seupdmaker% to /PSP/GAME/
thats ur psp

-Get the 1.50 and 2.71 sony updaters and put in the seupdmaker whithout the %

take 1.5 eboot and rename to: 150.pbp

take 2.71 eboot and rename to: 271.pbp


-Run the program on ur psp this will creat the DXAR file

-The program will verify that the SHA-1 of the generated file is correct.

-Once that you have done this, you can save the DATA.DXAR file to skip this step in the future.

Flashing 2.71 SE
----------------

-Go get the files in newinstall called seflasher and 271seflasher% put in ur psp( /PSP/GAME ).

- Copy the generated DATA.DXAR file at 271seflasher directory.
This file, at release SE-B, should have ALWAYS the MD5 96B4E3ED430A591B077624FC326622AC
and SHA-1 9956936EADF91D578D4087499B7211B9429E99F7.
Anyways, this time, the dxar creator will have told you if the file was indeed correct.

-U can now runthe flasher if ur battery is more than 75% i recomend 85 to 90% for safty...

-The program will continue showing an agreement. Press X to accept
it and flash the custom firm, or R to cancel and exit to the XMB.

- If you accept, the program will flash the custom firmware. DONT shutdown the psp and DON'T
quit the memory stick.

- After finished, you psp will be rebooted to XMB... of 2.71

There u go hope that helps some pepole....
See any problems just tell me and i will fix them... in the instructions not the program...lol

Downgradeing back to 1.5
_______________________

-you have to have 1.50 official sony update, then rename it "UPDATE.pbp" and put in in


-x/psp/game/recovery

-Then run the recovery mode shut off psp by holdinging the power switch than turn it on holding the "right trigger" than click run recovery thing...


Games
____________

- im not sure if this applies if u start from scratch but if u update u have to make a folder named ISO in ur root for any homebrew games to work....




If that was even to compicated i have a diagram....

Run the progame whith at least 75% i recomend 80-90%
Keep clicking x when promted till u are done(do not turn psp off or pull out memory card)

UPGRADEING FROM 2.71 SE - B to SE - B' to SE - B"
_________________________________________
