File has been updated with the new downdater released on 9/2/06 as it contains a crucial fix.
As some 2.71 PSP's say hello to the world, others will be saying goodbye at the same time as a downgrader has been released. 1.50 User Instructions
1. Dump File SetupCopy the folders downhelper and downhelper% from the folder 1.50 HELPER folder to /PSP/GAME/ in your memstick. (The DownHelper can be downloaded below)
2. Obtain the 1.50 update EBOOT and put it in /PSP/GAME/UPDATE in your memstick. You may find the 1.50 update in our download site here.
3. Initilize the downhelper program.
4. It will dump your flash and some files from the updater eboot to the memstick. (These files are illegal under US copyright laws, so please do not distribute them in the comments or on our forums)
5. After that, the program will exit. You can now delete the updater from /PSP/GAME/UPDATE
6. You'll notice that you have a new folder in the root of your memstick called "DOWNDATER". (See diagram on right for arrangement - click to enlarge)
7. That's the folder you'll have to send to a 2.71 owner to let him downgrade.
2.71 User Instructions
1. Download the Downgrader below and copy the files inside MS_ROOT to the root of your memory stick.
2. Wait for someone with 1.50 to pass you a folder called DOWNDATER and copy it to the root of your memstick.
3. It is recomended that you have the psp at more than 50% batteery and connected to AC
4. Go to the XMB Photo viewer.
At this point will one of the following things:
o You'll see a full red screen. This indicates that the downdater is doing its job. Wait for it to finish. When it finishes it will crash on purpose. Restart your PSP manually and you'll probably have a 1.50 if nothing went wrong.
o You don't see the red screen. This indicates that the downdater code has not started to execute. (even if the memstick blinks (or not), It doesn't matter! If the screen is not red, you can safely restart the PSP at this point and try again).
This happen because of inestability in the tiff. Don't worry, just restart the PSP and keep trying until you reach the red screen of the downdater. The downdater code is NEVER executed partially. It's either executed totally or nothing. It depends on "luck" but usually the downdater will start to execute in a average of 1/10 times. Things that may increase the probabilities:
- A fresh formatted memory stick.
- A 32 MB memory stick (and fresh formatted)
