Devhook v0.52 Released

Only a day after TA-082 PSP's are downgradable, Booster hits the scene with a new Devhook, sporting the version of v0.52. I'm wondering if this program will ever reach the big numero uno (number one), but that may never happen, but there is another number concerning this release besides the version number, the new maximum firmware emulation! This new iteration of Devhook can emulate firmware 3.03, but you will still have to use the psar dumper (separate from devhook)

This new version of Devhook however does not fix the Pop's emulation issues on the emulated firmware, but it does emulate the majority of 3.03 which would aid in the execution of 3.03-only UMD's (not produced yet, but will be most likely in the near future). The installation for this new version is similar to the installation of the previous devhooks, just you need a new psar dumper, of which is bundled (thanks vb_master) with this new Devhook download.

So, just as we were unwrapping our downgrader for 2.71 TA-082 PSP's, Booster surprised us like Dark_Alex and his little elves (Mathieulh and Harleyg).  As 2006 is coming to a close we are left with some of the greatest PSP homebrew advancements, and what a better way to celebrate the end by saying "thank you" to all those who helped to make it one of the greatest! Show you are thankful and post so in our comments, I'm sure everyone would enjoy to hear that! So, you can download one of the year's greatest applications (Devhook v0.52) below and read on how to install it -

Installation

1) Download 3.03 Firmware Eboot (below)
2) Download Devhook v0.52 + PSAR Dumper from C+D (bundled below)
3) Extract all Files
4) Move PSAR_Dumper2 and PSAR_Dumper2% to PSP/Game directory
5) Download PBP Unpacker (below)
6) Install it on computer and run after installation and click "Open"
7) Navigate to the 3.03 eboot file and open it, then extract the files to any directory
8) Move the DATA.PSAR file to the root of your memory stick
9) Open up the extracted devhook folder and move dh, fbm and PSP into the root of your memory stick
10) Disconnect your PSP and run the PSAR dumper from your memory stick via the XMB and follow the on-screen instructions (press X to dump)
11) Connect your PSP to your PC and copy the newly created F0 folder (root of your memory stick) and move it to dh/303/
12) Run Devhook v0.52 now and go down to flash install (uninstall the flash configuration if you have previously installed a previous firmware) and click install configuration (first option I believe). Hold O for a few seconds to confirm.
13) Now go to firmware and select 3.03 and boot up Devhook, good luck and have fun!

2.71 TA-082 Firmware PSP's Now Able to Downgrade!

Just when you thought Santa (Dark_Alex) couldn't surprise us with anymore presents for this holiday season, he has! We have a downgrader from Dark_Alex with the help of Mathieulh (right-hand man) and Harleyg. Just today it was announced that 2.71 PSPs running Dark_Alex's HEN-D will be able to downgrade their PSPs to a lower firmware (1.50) with this new program.

Unlike previous downdaters that require 1.50 helper files (illegal to distribute), this downgrader uses the raw 1.50 update file which is not illegal to distribute, so this process is much easier than previous downdaters released by Dark_Alex.

This program is specifically designed for 2.71 HEN-D users with a TA-082 motherboard. HEN-D, which enables 2.71 users to execute homebrew via the XMB, will be required for this downgrade process, and if you do not have it you can download it at the link provided below. Dark_Alex has also provided a detailed installation of this process detailed in the readme (please read the readme after you download).

   1. Copy the UPDATE and idstoragechange folders into /PSP/GAME/
   2. Get the official sony 1.50 eboot and put it in the /PSP/GAME/UPDATE folder with the name of UPDATE.PBP
   3. Run HEN-D if you are not already running it.
   4. Execute the idstoragechange. It needs 75% battery. It will change some keyes of your idstorage needed to downgrade the ta-082.
   5. The program will exit to the XMB. Now execute the generic downgrade, which will show in the xmb as "Update X.YX" in the psp language.
   6. The generic downgrader will also need 75% battery. IT will downgrade your psp to 1.50.
   7. At the end, it will ask you to press X to restart the psp. Do it.
   8. If all went fine, you'll receive a blue screen telling you to press O. Do it, and reenter your settings. Welcome to 1.50.
   9. If things didn't go that fine, you'll have a non-functional psp, aka brick.

Warning: As always, there is a chance that you may brick your PSP running a downgrader, so please try this at your own risk and follow directions exactly.
