These days, Dark_AleX has made it a habit of making big news at least once every week. And might we add, a great habit at that. Just yesterday, he released a generic downgrader which made it a piece of cake to anyone who wanted to downgrade. But in case anyone looked harder, you would've noticed that the file was named updateflasher.zip/rar.

We're sure many people got curious of the fact that a downgrader was named as updateflasher. Well, although we have known about it for a little while now, we decided to keep quiet so that you guys would get a huge surprise, come release day.

And well, we guess it's time to let everyone know what Dark_AleX has been working on. How about we tell you that we can run all 1.5 kernel mode homebrew on our 2.71 PSP. While we're at it, we might also add that it's a seamless package. You won't know that the PSP has been modified in any way, apart from the fact that you can run homebrew properly on the 2.71 firmware. All the magic is courtesy of Dark_AleX and his 2.71 Custom Firmware, or as Mathieulh likes to call it, 2.71 SE-A.

This modification will not run on a TA-082 PSP. Do not even try it out. It will surely brick your PSP.

• 1.00/1.50 Eboot support (both kernel and user mode).
• 2.71 Eboot support (both kernel and user mode).
• Runs on 2.71 VSH.
• Ability to run Devhook (both 1.50 and 2.71 versions are fully compatible).
• Ability to run all 2.71 (and lower UMDs).
• 1.00/1.50 prx executable support.
• Support both KXploited and unpatched eboots for 1.50 kernel.
• Support any 2.71 homebrew coded for HEN C.
• Compatibility is 100% for 2.71 homebrew and approx 99% for 1.00/1.50 homebrew.
• Recovery mode.
  

1. Mathieulh has said that after installing the custom firmware, there isn't much space left on Flash0. So it's best to use the downgrader which formats the whole Flash0 first. That way, you can be sure that there aren't any useless files on your Flash.
2. You will need a 1.5 dump. Those are only available if you're on a 1.5. Though you won't have to worry, Dark_AleX has bundled a helper program which will help you make a firmware dump easily.

• First, copy the seupdmaker and seupdmaker% folders to your PSP.
  
• Now download the 1.5 and 2.71 update eboots from our site and put them in the seupdmaker folder with the names 150.PBP and 271.PBP
• Using the Helper program, make a firmware dump.
• Once done, copy the generated .dxar file from the seupdmaker folder to the 271seflasher folder.
• Then, simply use the update flasher to flash the custom firmware on your PSP!
