Note: If at some point your screen goes black for more then a few seconds Hit the brightness
key gently a few times. Be careful not to bump the power or other buttons. In some cases the brightness goes to off.
==Instructions==
1. Before you start, format your memory stick and reset your default settings.
A. Format MS by going to System , Format Memory Stick. press X
B. Push down to restore Factory Settings
2. Download the official Sony 1.50 eboot and rename it to UPDATE.PBP, and put it in the
MSroot/PSP/GAME/UPDATE folder of this download with the name of UPDATE.PBP DO
NOT OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP! Doing so will brick.

3. Create a USB connection between your PSP and computer.
4. Copy the contents of the MS_root folder to your memory stick root, click yes to overwrite. Do
not put the readme on the psp.
5. Run HEN (see instructions from hen280 readme on the next line)
- Go to the PHOTO viewer of the XMB and enter in the folder "HEN_280".
- If the psp just freeze, reboot your psp and try again. Currently the tiff is very unstable and it is only executed sometimes.
- When you run the program, you'll see a coloured screen that can be one of two colors:
* Red: the files couldn't be written to the flash (it happens a few times). Just keep trying.
* Pale Blue: The files were written succesfully, and HEN is active. After that, the xmb will be
rebooted. Now you can run the homebrew in format prepared for 2.71. (see details below). Note
that a pale blue screen will appear again every time the PSP reboots with HEN active.
6. Execute the 1.5 enabler on the PSP. It needs 75% battery. It will verify/make your psp able to
run 1.5 and enable downgrading the TA-082 or TA-086 PSP.
**note 1.5 enabler will tell you if you can run 1.5 or not... if it says you cannot press x to alter keys, donot continue till it says your settings will run 1.5
7. The program will exit to the XMB. Now run the generic downgrade, which will show in the XMB
as “Update X.Yz” on the PSP.
8. The generic downgrader will also need 75% battery. IT will downgrade your PSP to 1.50.
9. At the end, it will ask you to press X to restart the PSP. Do it.
10. If all went fine, you’ll receive a blue screen telling you to press O. Do it, and re-enter your settings.
Welcome to 1.50.
