Generic Downgrader for 2.71

[tikibarber]

ok heres what I did...

1. RESEARCH and READ!!! Everything that goes for the Readme.txt that comes with every .zip or .rar you are about to install. Read forums and posts like you obviously are

still with me?????

2. Know your board...
here's a picture of what you look for

Blue good Red bad

If you have the code on the left like the picture then you dont have the Ta-082 look closely.

So if you dont have the bad board then you're free to downgrade as long as you aren't past firmware 2.71 at this point. I was 2.6 when I started and updated today to 2.71.

If you do have the Ta-082 (aka Bad board) then the furthest back you can go is 2.5. Any further back will brick your psp 100%. Also you must be no higher than 2.71 firmware when you begin.

3. Ok so you have the good board and you want to downgrade from 2.71 . Im assuming you already upgraded to 2.71 from whatever you had before starting. I was 2.6 myself when I started.

Grab the firmware eboot.pbp that is legal and offered on QJ.net here is 1.5 ok extract the folder to your desktop for use later on.

Ok lets grab Hen C now that we're 2.71
CLICK AND DOWNLOAD
Unpack the file and place the folder on your desktop like you did with the first one.

Now for the actual Downdater file
Wraggster has it attached to the first post in this topic. HERE Unpack the file and place the folder on your desktop.

You should have 3 folders on your desktop at this point...Eboot_1.5, hen_c, and Updateflasher.

4. Ok now I suggest having a clean reformatted memory stick. Also make sure your unit is at 100% battery..First step is to Open the "hen c" folder on your desktop and find the "MS_ROOT" folder, this is the only folder within the "hen_c" folder we are going to use. Open "MS_ROOT" and highlight all the files in there. Copy those to the root of your memory stick. When it say overwrite click yes to all and move on.

Ok after hen c was on my stick I disconnected froom my PC and went to the photo viewer on my psp. There'll be a file "HENC"....take a deep breath and keep your eyes on the psp screen.

The first time you run the program, you will see a blue screen, and then a screen that can be either two colors:

* Red: the files couldn't be written to the flash (it can happen a few times). Just keep trying.
* Green: The files were written succesfully. After that, the unit will be reboot.

The patch (HENC) will remain resident in memory, and even sleep mode won't delete it. Only a hard reset will remove the program from memory.

When you do a hard reset, you'll have to run the tiff (HENC) again from the photo viewer. This time there won't be a green or red screen, just a blue screen and then a reboot, since this time there is no need to write to the flash.

5. Ok now once that works make sure HENC is going for this step.
Open the "updateflasher" folder on your desktop and once again within this folder you'll see a "MS_ROOT" folder. Open it and copy the "PSP" folder to your memory stick. Click yes to overwrite.

6. Now GO to your memory stick and open your "PSP" folder then "GAME" and finaly "UPDATE"
GO into the "EBOOT_1.5" folder on your desktop and rename the EBOOT.pbp to UPDATE.pbp. Now place it inside the "UPDATE" folder you opened on your memory stick.

7. We're ready now this is the part where I crossed my fingers. We have HENC active and everything in place...Disconnect unit from PC and make sure battery is 100% again. Ok lets downgrade!!!
Go to the controller icon on your psp (game) and then down to the memory stick. Hit X and find the eboot. It was labeled x.yz or something like that when I clicked it. Anyway thats the update...er downgrade


watch the screen untill it finishes and reboots.

If all goes well...and it should. It did for me and Im retarded

Welcome to 1.5
I'd erase your mem stick now tho

Where do I stop if I have a TA-082? And what can't I do with 2,5 that I can do with 1.5?

I have also seen games that I can download from torrent sites that have 2.71 firmware....do I still need to downgrade?

You possibly have renamed the actual downgrader program by mistake, which is most likely the cause of the problem. You only rename the offical update package of whichever firmware you want to go to. If that is the case, just rename the downgrade program back to EBOOT.PBP. By the way, it's about 63kb, the downgrade package between 13-15MB (depending on what firmware version you wish to go back to).

Magicmush, do not discuss ISOs on these forums as it is against the rules. You will be highly likely to get banned and I am sure you don't want that.

do we need hav both ic6001 AND ic1003

I'm sorry if this question has been up before, but I've followed the instructions from 'chiefy' and everything worked until I was going to downgrade. It said "The game could not be started (80020148)".

I've got full batterytime, and I've tested to install it with and without the cable. But I can't get it working.
