Downgrading Using 6.20 TN-B Hen

[Image: 0701B000F500343435.jpg]

Warning!
Remember that all the firmwares are not supported by all models of PSP!
So do not try to install:
Below the 3.60 firmware on a PSP Slim (2000)
A firmware below 4.20 for the PSP 3000
Below the 5.70 firmware on a PSP GO


What you'll need to downgrade to firmware 5.03:

PSP (all models) equipped with firmware 6.20
Official firmware 6.20 (PSP GO)
Official firmware 6.20 (PSP non-GO)
The Half Byte Loader
The demo for Patapon 2
The modified backup of that demo
The NF-B 6.20
The application Psar New Dumper with firmware 5.00 eboot
The firmware 5.03


If you want to downgrade to another firmware:

PSP (all models) equipped with firmware 6.20
Official firmware 6.20 (PSP GO)
Official firmware 6.20 (PSP non-GO)
The Half Byte Loader
The demo for Patapon 2
The modified backup of that demo
The NF-B 6.20
Applying New Psar Dumper eboot with a firmware lower than that to which you want to downgrade (the eboot should be placed at the root of the Memory Stick and must be named EBOOT.PBP)
The firmware that you want to downgrade


Tutorial

* Go to Game> Memory Stick and select New Psar Dumper

[Image: 0600AB003600343442.png]

Go to that folder. Then open the folder vsh and finally the file etc. . You'll find a file named v ersion.txt . Copy it (Right Click> Copy)

* Go back to the root of your Memory Stick

* Go to the folder seplugins (create it if it does not exist) and paste the file version.txt (right click> Paste)

* Quit the "USB mode" on your PSP


* Press [Image: select_0028001400308732.png] to display the TN VSH Menu

* A line Fake Index.dat , press [Image: droite_0014001400308682.png] Enabled appears

[Image: 0801B000F500343436.jpg]

* Select Restart VSH to validate changes

* Now that your information is biased , go to Game> Memory Stick to start the update 5.03

[Image: 0901B000F500343434.jpg]

* Once the update is complete, you will need to restart your console. A blue message will appear on the screen, press [Image: rond_0014001400308712.png]

* It'll just enjoy the Custom Firmware 5.03 GEN-C for HEN

@Ninja88 probably because they're trying to downgrade their psp 3000 lower than 4.20.

The BEST thing that I like in Custom Firmware is that it can use custom themes unlike in Official Firmware. If official firmware can use ctf themes I'll switch to Official Firmware. Yay
