This is my second modificaction on the MaTiaZ TIFF exploit that loads and executes the Davee's kernel exploit that enables ChickHEN. It works 100%, tested only on PSP 2000 this time because I didn't have access to PSP 3K, but I did it for those who didn't get the first modificaction to work.

This only works for OFW 5.03

Please follow the instructions STEP BY STEP (for Windows & Linux):

1. Power on the PSP
2. Connect to the PC via USB. Our OS should tell us it has been connected.
3. Open the folder of the PSP and copy the download (see below) there (in the root of the MS). I suggest using a MS with 1 GB or less, as they give better results.
4. Decompress ChickHEN Mod.zip. Answwer "Yes" to all replacements.
5. Now we do a safe extraction of the PSP (do not extract the USB cabla altogether) and switch to PSP (now tranquility please )
6. Press O to cancel USB connection
7. Go to Photos, down to Memory Stick and press X
8. Wait for the egg image to load in the ChickHEN Mod square.
9. When it's loaded press X (no need for timing here)
10. PSP 2000: DO NOTHING ELSE, JUST WAIT
11. PSP 3000: SCROLL DOWN TO LAST IMAGE (thanks to mvisions)

If it doesn't work (that kind of things happen), just power on again and try from step 7.

Please indicate your PSP version & MS brand and size in any comments, thanks!

For more details:

This time I got rid of the first part of MaTiaZ's code, the part that writes black color on the screen. This should speed up the H.BIN loading and get around any cache writing at the same time.

The other modification I did was putting a branch instruction pointing to the beginning of the real code at the end of the egg, just before the strings, to make sure the egg code is executed if execution starts after it.

I also refilled the zone before the code beginning with zeroes, to make sure they are all nops, as there was some bits set.

Any questions about this, please comment here.

Happy hacking

Excuse me, I think MHUSpeed V3 is fake !!! But many people don't believe me.
MHUSpeed V3 just only changed files name and info showing on PSP.
(h.bin → speed.bin and ChickHEN R2→ speed3.)
That infamous authour of MHUSpeed V3 steals your works.

Sorry for my bad English.

You are a bit off-topic there.....I suppose from ure comment that you use chickHEN+cfwe to play games. Well I was using cfwe 3.30 and the speed up plugin actually works, which was put in place by the same people that made the MHU so in essence they should be the same.....but if u r worried that it is a fake that switch back to an older cfwe......although I recommend 5.03GEN-B (full) as it patches some of the latest games, which to point out before u complain has no speed up plugins. I dont even use the speed up plugin cause honestly u dont need it for most of the games unless u r getting lag like crazy...

On topic: will try this out one I get home...I have psp 2001 88v3 and running 5.03 GEN-B (Full) currently with the modified chickHEN image by m0skit0

MHUSpeed V3 isn't CFWE, it's a TIFF exploit program, like ChickHEN (or say it's just a renamed ChickHEN R2 Mod by m0skit0).
Here is a link: http://dl.qj.net/download/mhuspeed-v3.html

It's not really a fake, but it doesn't do much either It's supposed to "speed" up the launch of chickHEN I guess. Some people think it works, I just think its just another random method that works for some people, and not for others.

They did credit m0skit0 for his TIFF.. even though they said "jpeg" lol..

I know mvisions, the author of MHUSPEED v3, and we already discussed this. He did some modifications to h.bin, although the TIFF image with the exploit is exactly the same as mine.

I would like to stress here that credits for the TIFF exploit go to MaTiaZ, and for the ChickHEN to Team Typhoon. They did the work and we're merely trying to make the TIFF exploit load better.

But I just saw two difference between h.bin and speed.bin. Any other modifications really ?

Well if these are the only two differences then

This works like a charm....I have psp 2001 88v3 with 8GB SONY Pro 2 Duo MS and 5.03 GEN-B (Full).....tried it 6 times and froze only once......it is also very quick to load.....thanks to m0skit0
