2.71 downgrader now available [Update 3]

Ok, someone, anyone--please help. I have acquired all of the files and want to begin the download (I have the text that tells me how to do it). Do I need to have someone else with a 1.5 psp to do this (or any psp, for that matter)? PLEASE HELP!!! I will pay money via paypal for someone who can successfully guide me through the process. Thanks in advance!

2.71 Downdater by Dark_AleX/Mathieulh/Yoshi

This software is free, unlicensed and comes with no warranty.
Despite it has been tested and it has worked, a program that rewrites a big part of the flash(flash0)
is always dangerous. You are the only responsable of whatever happens to your psp using this
unlicensed program.


This program requires that someone with a 1.50 runs a little program and send you the output so
you can init the downdate process. (by legal reasons i cannot provide those files directly, that's why
this is needed).
The 1.50 program is TOTALLY safe, it only dumps the flash of a 1.50 user and it also extracts some special
prx's found in the 1.50 updater.

The downdater directory outputted is exactly the same than the created by the 2.60/2.50 downdater.

IMPORTANT NOTE: TA-082 users, this doesn't work on these psp's. DO NOT RUN IT.

Instruction for the 1.50 user
-----------------------------

1) Copy the folders downhelper and downhelper% from the folder 1.50 HELPER folder to
/PSP/GAME/ in your memstick.

2) Obtain the 1.50 updater and put it in /PSP/GAME/UPDATE in your memstick.

Some download links for it:

http://dl.qj.net/PSP-Firmware-1.50-File-(EBOOT)-North-America-PSP/pg/12/fid/163/catid/163

3) Init the downhelper program.
It will dump your flash and some files from the updater eboot to the memstick.

4) After that, the program will exit. You can now delete the updater from /PSP/GAME/UPDATE

5) You'll notice that you have a new folder in the root of your memstick called "DOWNDATER".
That's the folder you'll have to send to a 2.71 to let him use the downdater.



Instructions for the 2.71 user
-------------------------------

1) Copy the files inside MS_ROOT to the root of your memory stick.

2) Wait 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:

a) You'll see a full red screen. This indicates that the downdater is doing its job.
Wait for it to finish. When it finish it will crash on purpose. Restart your psp manually
and you'll probably have a 1.50 if nothing went wrong.

b) You don't see the red screen. This indicates that the downdater code has not started
to execute. (even if the memstick blinks(or no), it doesn't matter! if the screen is not red, you can safely restart
the psp at this point).

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 downdate.
The downdater code is NEVER executed partially. It's either executed totally or nothing.

It depends of "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)

Can someone please tell me how to use this thing!

I got the red screen, but only for about 5 seconds, and it reads from the stick for about 2.....My total file size is around 12MB, does that sound right? It goes black, and I can power it back on into 2.71

what the hell is that picture of? how do i tell if i have a TA-082 PSP or not?

1st: Make sure you do not have a TA-082 PSP by looking here http://www.modchipstore.com/support/images/ta82spot.jpg

2nd: Download this http://www.psp-hacks.com/file/753 (includes all necessary files)

3rd: Put the downdater folde rin the main screen. where you see PSP and MP_ROOT. Put the .tiff image in photo and put the .bin in the root where you see PSP and MP_ROOT. Thats it and run the .tiff.

4th: Go to the xmb photo viewer.

At this point will one of the following things:

* You’ll see a full red screen. This indicates that the downdater is doing its job. Wait for it to finish. When it finish it will crash on purpose. Restart your psp manually and you’ll probably have a 1.50 if nothing went wrong.
* You don’t see the red screen. This indicates that the downdater code has not started to execute. (even if the memstick blinks(or no), it doesn’t matter! if the screen is not red, you can safely restart the psp at this point).

Remimders: It is recomended that you have the psp at more than 50% batteery and connected to AC

Some people got it running on their 20+ try so dont worry if doesnt run after a first few try. Be patient, just restart it until you see the red screen.
