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
--
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 msot 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.- 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.
- 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 PSPUpdates 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!
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.
Thanks PSPUpdates
