2.71 Custom Firmware SE-B Released! *UPDATE*

2.71 SE-BOne of the most anticipated releases of the fall has arrived on your doorstep (figuratively speaking)! Dark_Alex has updated his 2.71 CE (Custom Firmware) to the “B” edition. If you have no prior knowledge of what this custom firmware is, or when it was released – We highly suggest that you read Pranav/Cyanide’s article concerning the first release. Unless you are “lazy” like myself, I’ll put this complex release into some simple sentences:

Dark_Alex released the 2.71 Custom Firmware as a succession to his earlier HEN_C release which patched homebrew to fully run it on the 2.71 firmware. With the 2.71 Custom Firmware SE-A being released around two weeks ago, the scene was introduced to an easier, and more user-friendly method of executing these previously incompatible homebrew. So basically, all those kernel applications that you’ve been dying to run are all executable with this custom firmware, with near endless possibilities.


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



With the first release of Dark_Alex’s Custom Firmware (SE-A), the basic features boiled down to the execution of homebrew by “regular” means like 1.50 firmware users have been doing for over a year now. With this newest addition to the custom firmware “family”, Dark_Alex has improved the previous features as well as added some new ones which will turn several heads –

  • ISO/CSO support
  • All previous incompatible UMD’s work
  • Loading of 1.50 homebrew from GAME folder and 2.71 homebrew from GAME271 folder – now supported
  • Execution of EBOOT on Startup
  • Ability to enable/disable the noplainmodulecheck patch in umds/isos (for advanced users)
  • Ability to force the use of boot.bin in umds

Read the full installation guide, and watch a short clip of the firmware in action after the jump!

UPDATE: We heard that Dark_Alex has made an update (you can get it by clicking the download link below), and here are the changes you can expect from it:

  • Fixed the problem of crashing if the iso folder didn’t exist
  • Added experimental no umd mode. By default it is disabled.

To install this, just run the new update from the game150 folder in either 2.71 SE-A or 2.71 SE-B. Here are other helpful stuff we got from the readme, which you may want to take note as well:

New configurations:

  • Use NO-UMD. It will enable the NO-UMD mode, whose compatibility is currently unknown, and probably less compatible than UMD mode. This is the main reason to release this quick update to know more or less the compatibility of this no-umd mode.
  • Use isofs driver also in UMD-inserted mode (in advanced). You probably don’t have to touch this, it’s mainly done for myself. If you do it, you may decrease the compatibility of UMD mode.

Note that if you want to change from NO-UMD mode to UMD mode, you have to do it in recovery. Because even if you have an umd inserted, but you have the NO-UMD in settings, the CF will use the method of umd emulation of NO-UMD, which differs a lot from the UMD one and may have a very different compatibility.

  • Ability to force the use of boot.bin in umds

So, with all these great new features, is it even possible to add more? Well, of course it is! There are plenty of features to look forward to in the next release (SE-C), and we have a sneak at what can be expected to come:

  • UMD not needed in SE-C for execution of ISO’s
  • USBHostfs support built-in
  • DAX ISO support

Now, comes the tricky part that most uses seem to have the most trouble with – installation. I myself have never tried out custom firmware (loyal 1.50 homebrew user), so I’ll list Pranav’s great installation guide as previously posted –


— Installation —

Here’s a set of instructions which will help you on your way towards firmware nirvana. It can only be applied from 1.5 firmware.

  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.

Here are the instructions to flash the custom firmware on a 1.5:

  • 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!

Note: Make sure there’s no UMD loaded to your PSP before making an update, just to be safe.

There are some precautions you have to take though. Make sure your PSP is not a TA-082. Secondly, make sure your PSP’s battery level is above 75%. And finally, be careful while using this application. It modifies your flash, so you have to be careful; any application that modifies your flash has a chance of bricking your PSP. It is indeed very necessary that you fully read and reread the readme file inside the download before proceeding.
