PSP 2.71 Firmware Emulation Support via Devhook!

Posted by Xavier Ashe on July 13, 2006

The PSP 'scene' is having some of its best times lately, what with the recent deluge of downgraders, and one of the most awesome pieces of homebrew, Devhook. And guess what? Booster has just raised the bar with his latest incarnation of Devhook. Apparently, the latest release supports 2.71 reboot. Or in other words, 2.71 Emulation! Now that we're caught up, the ball is in Sony's court!

Here's a small guide on how to get it running:

  1. Download Devhook 0.44 and put everything on the memory stick as usual.
  2. Download the 2.71 Firmware update from our site.
  3. Open the EBOOT.PBP with PBP Unpacker or similar and extract the DATA.PSAR file.
  4. Put the DATA.PSAR in the root of the memory stick. (Not in any folder)
  5. Run the included Devhook installer on the PSP (install flash0 and flash1).
  6. Extract
    Devhook 0.44 again and overwrite everything in the dh folder (its going
    to be a couple of .txt which include the path for the prx's)
  7. Use the 2.71 Decrypter to obtain your own copy of a decrypted reboot.bin file, or make use of Google to find one online
  8. Place reboot.bin in ms0:dh1reboot.bin

Note: You'll need the decrypted Flash1 files from 2.60 Firmware! (reboot.bin, system.ireg and system.dreg)

Now you can enjoy all that the latest PSP firmware has to offer on your 1.50 PSP – including the flash-enabled PSP Web Browser! Want the rest of the world to know about one of the greatest PSP conquests yet? Be sure to Digg it!
