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 5.03Please follow the instructions STEP BY STEP (for Windows & Linux):
- Power on the PSP
- Connect to the PC via USB. Our OS should tell us it has been connected.
- 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.
- Decompress ChickHEN Mod.zip. Answwer "Yes" to all replacements.
- Now we do a safe extraction of the PSP (do not extract the USB cabla altogether) and switch to PSP (now tranquility please
) - Press O to cancel USB connection
- Go to Photos, down to Memory Stick and press X
- Wait for the egg image to load in the ChickHEN Mod square.
- When it's loaded press X (no need for timing here)
- PSP 2000: DO NOTHING ELSE, JUST WAIT
- PSP 3000: SCROLL DOWN TO LAST IMAGE (thanks to mvisions)

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
