Section 3	More Available HEN's.
Section 4	Available CFW For PSP 01g, 02g.

First I will explain a few words that are used in the PSP scene.

CFW = Custom Firmware/Update ....................................................OFW = Official Firmware/Update
HEN = Homebrew Enabler ..............................................................XMB = Xross Media Bar (Main GUI)
ms0: = Root Of Memory Stick .........................................................ef0: = Root Of PSP Go (16GB) Storage
ISO = ISO file is an image of the contents of a UMD ...........................CSO = CSO is a compressed ISO image

Thank you Total_Noob for 6.20 TN-E HEN.

Section 1:

The difference between Hen & CFW: Is that CFW is a full firmware which is flashed into your PSP main memory (flash0) A HEN is a firmware that is kept in your PSP's RAM which means when you turn your PSP off in Hen mode the RAM will be deleted and your PSP will return to its normal state.

Bricked PSP = A bricked PSP is one in which the firmware has been corrupted so that the PSP will no longer start up. It has, essentially, become a very nice-looking brick.

Homebrew: Refers to programs, such as games and utility software, that are made at home by individual people (as opposed to development companies).

To start select your PSP to download a OFW: (Note: This is OFW 6.20 because a hen is available for it) If you are already on 6.20 OFW skip this part. (However if your firmware is higher than 6.20 skip to Section 2)


        


Extract the rar file using 7zip or winRAR. You will then find a file named EBOOT.PBP.

1: Using your PC, create a folder named "PSP". Within the "PSP" folder, create a folder named "GAME". Within the "GAME" folder, create a folder named "UPDATE". (Folder names must be in all uppercase letters).

    
MEMORY STICK           PSP                   GAME                UPDATE              EBOOT

2: Copy the EBOOT.PBP you downloaded to your UPDATE folder.

3: To start the update data. Select either (Memory Stick) or (System Storage) under (Game) from the home menu, and then select . Press the button to start the update.

  

Now you are on 6.20 OFW. But now wee want to get to 6.20 TN-E (which is a HEN).



To start

1: Extract 6-20TN-E.zip file which you have downloaded.

2: Copy the files & folders you extracted into your PSP (Memory Stick) or (System Storage)

3: Run 6.20 TN-E like a normal (Game) from the home menu.

4: To confirm that the HEN was successful. Select [System Settings] under (Settings) from the home menu, and then select [System Information]. If the [System Software] field displays the version number of the update, the update was successful.



Now that you are on 6.20 TN-E you might want to add ISO back-up support because 6.20 TN-E HEN doesn't have a ISO loader.

To start

1: Extract aLoader-1.25.rar which you have downloaded.

2: Open up the seplugins folder and copy aLoader folder to your own seplugins folder.


seplugins              aLoader

3: You will also see two txt files named _go_vsh.txt & _vsh.txt in the seplugins folder.

4: If you are on (PSP GO) you open _go_vsh.txt and copy the txt ef0:/seplugins/aLoader/aloader_vsh.prx 1 & If you are on you open _vsh.txt and copy the txt ms0:/seplugins/aLoader/aloader_vsh.prx 1.

5: Now open up your own seplugins folder and you will see a vsh txt file open it up and you will see this:

ms0:/cxmb/cxmb.prx 1

cxmb.prx is support for custom PSP themes. Now paste the txt you copied from step 4.

So it should look like this:

ms0:/cxmb/cxmb.prx 1
ms0:/seplugins/aLoader/aloader_vsh.prx 1


Remember to change ms0: to ef0: if you are using PSP GO's Storage.

1 = ON            0 = OFF


Now go back on your PSP and press select:

This will bring up a TN VSH MENU

VSH menu allows you to change around some option while in the XMB.

Now go down to the option RESTART VSH

And your PSP will then restart. Now your done


To play your backed up game you have to make a new folder in your (Memory Stick) or (System Storage) called ISO and you just put your ISO or CSO game in there.

       
MEMORY STICK            ISO

To change some option in the aLoader you press and hold L-Trigger, then aLoader shows a menu change the option that suits your game.
