Pandora's battery was quite a hit, but the sad part of it is that you need a homebrew capable PSP to create the battery. Well, if you are on a firmware below 2.80, then you can create one anyway. Here are the steps:

1. Get the 2.71 Update, and update your PSP to 2.71
2. Download the 0.4X Devhook Launcher + HEN-D and install them
3. Download the 1.50 US dump (http://www.psp-hacks.com/file/8)
4. Copy the dump to 150 in the dh folder
5. Download Pandora's Battery and follow the readme normally (make a magic memory stick, not a battery)
6. Go to devhook and set the language of your choice. DO NOT make a battery yet
7. Install 1.50 from the following link http://www.sendspace.com/file/a645il (thanks to Erikih for the link)
8. Make a folder in the root of the memory stick named registry and copy the 1.50 devhook registry to that folder
9. Boot into 1.50 from devhook and back up your serial, and then make a battery
10. Shut off the PSP and switch the WLAN up and take out the battery
11. Put the battery in and it should boot into 1.50, to boot into the menu, switch the WLAN down.
12. If it didn't work, when you make the memory stick, if on Vista, then run it as administrator.


Have Fun!

Now, after long waitings finally the new version of 2.71 SE released. 2.71 SE-C !!!
You can download it on: http://www.dark-alex.org/

These are the Changes on 2.71 SE-C:

- Load of plugins from the ms
- Changes in the HEN core:

 * Fixed a bug in the loading of big user prx's, that affected a plain prx of socom2 umd, and some
   homebrew prx's.

 * Bypassed a crappy $ce protection that prevented the umd to be mounted if the application was run from
   the memory stick

 * Usb mass storage couldn't be loaded by homebrews in non-devhook version because semawm.prx is sign checked.
   HEN now applies the algorithm to reverse the sign check, letting this and the rest of firmware
   modules to be loaded by a homebrew.

- Added a SDK for SE-C/HEN-D. (in a separate download)

Dark_AleX has done it again.
He has released the Homebrew Enabler 2.71 Revision D ( HEN-D )
The download is with an included Devhook-Version.
