2.71 Custom Firmware SE-B Released! UPDATE

One 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'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

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.

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.

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.

Download: [2.71 Custom Firmware SE-B]

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.

Great Work Dark Alex

Re: doormat (Unregistered) - 2006-10-25

» Nothing is perfect!

Unfortunatly, this didn't work for me. Upgrading from SE-A seemed fine, but my PSP hangs whenever I try to access the memory stick. Recovery time! :-)

I'm not suffiently in need of the upgrades this firmware offers to try it again. I'll reflash to SE-A when my battery is fully charged (which is super, BTW.)

Re: kirkmc02000 (Unregistered) - 2006-10-25

» replying

if you dont have an iso folder at the root of your mem stick even if you dont run isos it freezes

Re: not (Unregistered) - 2006-10-25

» Suggestion

Dark Alex, very nice work and SE-C is going to be even better with the "no more UMD" option. Rock on. Anyway, a small suggestion based on your readme doc in this firmware and in SE-A.

For the love of god man, change the error message for the SEC flash and language changes. Right now you've got "DADADADA" and "987654321"... I know those have to be error messages you put in. Why can't you have something meaningfull in there?

Try these... SEC Flash Not Allowed or SEC Flash Update Unsupported and for the other... Language Selection Invalid or Language Selection Not Supported.

People won't have to freaking guess and search when they get those then, not to mention it's a whole lot cleaner looking too.

Come on dude, stop with the basic ass hacker error messages. You want to be a cool developer, set an example.

That is all, keep up the good work!

Re: Fla(v)eZ (Unregistered) - 2006-10-26

» nice

i rly luv dis cso/iso option buh i think it will be better if he mar a new catgort for tha iso

like there is setting photo music network there should be another one call ISO's n tha memory stick icon should lead to ms0:pspiso

this way people wid alot of homebrew can be more organized and serperate tha iso from applications

just my opinion

Re: atrusredtalon - 2006-10-26

» 2.81

I just got Ace Combat X (which requires 2.81 fw) running on this. Great job Dark Alex!! Keep up the awesome work!!

by taekwondokid (Unregistered) - 2006-10-25

» YEAH FINALLY

by the way first
but i am not gonna need this cuz i have a v1.5 custom fw already...

by nobody (Unregistered) - 2006-10-25

» nice but although

thanks again dark alex!!! though it seems that whatever firmware that can play iso's... you're still screwed if you have the ta-82.

Re: me (Unregistered) - 2006-10-25

» no!

U can use Hen-C and Devhook if u have TA-082....

Re: Derek (Unregistered) - 2006-10-26

» Wha?

Hen-C you mean Hennesey?

by akuma2099 - 2006-10-25

» cool

This is a great piece of software but for me anyway I think I will stick with devhook as I don't like mucking about with flashing my firmware. I'm just worried that with my luck I will end up screwing something up.

by taekwondokid (Unregistered) - 2006-10-25

» YEAH ENOUGH OF BRICK CHANGES...

well i don wanna go with this v2.71 SE-B fw cuz i already took enough brick changes since my warranty is over...
also i heard that the Harleyg's Custom Firmware Patch v0.2 is better since u are using a v1.5! (less risk)

Re: LordSturm - 2006-10-25

» Nahuh...

Yes, flashing for 5 minutes is a bit more of a risk, but so is any update...

Besides Harleyg' is/was behind some component of this custom fw, and do remember who made the FIRST custom fw? ( Dark Alex, the author you are facing here. )

Besides, Casual is gunna make 1.50 pwn all.

this take's 5 minutes 2 flash?

» USB option?

Do I still need to use Devhook/vshex to run .iso/.cso games from my HD via USB ?

Re: Advertising -

Re: KirbySS - 2006-10-25

» Yes

Yeah, but apparently it's planned for SE-C.

Re: TPot - 2006-10-25

» No.

Read the readme - it's what it is there for.
ISO/CSO files show up under the memory stick games - but still require a UMD to be in the PSP.

Re: TPot - 2006-10-25

» Sorry.

Mine was a stupid comment I should read the question better first. KirbySS was right - you have to wait for the next version to do it via USB.

Re: JeDi (Unregistered) - 2006-10-25

» WiFi!

It does require such a program for the moment. I hope running games from a WiFi-connected server will be possible some time soon, cause playing with the usb cable isn't that mobile, is it?

What do I do if I have firmware 2.5... upgrade to 2.71??

Please help

lame fanjita imposter u tard face dark alex is probrably the best thing that has happened to the psp community

Re: Pranav (QJ. NET Staff) - 2006-10-25

» 2.5 -> 1.5 -> 2.71 SE-B

Downgrade to 1.5, then generate the .dxar file and flash it to obtain 2.71 SE-B firmware.

But make sure that your PSP isn't a TA-082.

WHOOOOOOO!!!!!!!!

TIME TO PARTAY!!!!! CHEERS!!!

by A2theC (Unregistered) - 2006-10-25

» Awesome

This is great, the only reason I didn't try this before is cuz I didnt want to change my GAME forlders and patch every game just to work for this FW. I have Devhook which plays my backups already, so why would I fuss with a FW that doesn't, that problem is fixed now too....YAY!!!!! :D

by KirbySS - 2006-10-25

» Quick question

Can I update directly from 2.71 SE-A? Or do I have to downgrade to 1.5 first?

by Advertising -

by anonymous (Unregistered) - 2006-10-25

» sooo

if you have 2.71 se-a then you have to go back to 1.5 then 2.71 se-b?

Re: Giskard2k4 (Unregistered) - 2006-10-25

» a-b

If you are already on 2.71 SE-A then read the Readme.txt file....there is an seb_update folder in the download....pop this into your Game150 folder, run the update and you are at 2.71 B...easy.
The rest is if you are already at original 1.50 or 2.71.

Re: anonymous (Unregistered) - 2006-10-25

» ooh

nice, thanks.

by Madlax (Unregistered) - 2006-10-25

» Uh..

Uh so basically if i have FW 2.6, i have to downgrade first? I cant just update to FW 2.71 and then install the custom? .> updated cause i was too impatient to play Valkyrie Profile: Lenneth

Re: _F1 - 2006-10-25

» -

Yes, you have to downgrade.

by NeoN HaZe. (Unregistered) - 2006-10-25

» Kick A55!!

Native ISO and CSO support??

Now my Girlfriend can play the psp without always asking me to load devhook.

I went from 1.50 to 2.71 SE-A. Now will update to Rev. B

A good bit of advice would be keep a copy of the recovery files in their correct directories on a separate mem stick (keep that mem stick v. safe). This will protect you in the event of a semi brick and your mem stick being corrupt.

Great Work Dark Alex - SOny must be chewing thier own behind to find out who you are ;)

yeh i bet the epsilon/modchip developers will be pissed aswell, rendering their modchips useless hahahaha, all those modchips are useful for now is motherboard replacement

Re: Zetsurin (Unregistered) - 2006-10-25

» Not really

The only modchip customers that would regret it are the ones that fried their PSP's trying to install it. I think the rest of them will be in front of us when firmware 3.0 ships.

by DaHandy (Unregistered) - 2006-10-25

Re: Sonny (Unregistered) - 2006-10-25

» No

on SE-B you can only play from ur mem stick on the SE-C,which Dark_alex is working on will be that function.

by Krisman - 2006-10-25

» Looks great

Moving 2.71 homebrew to a GAME271 folder sounds better to me.
My only question is if themes PSP works with this one. I suppose I could use the 2.71 SE Customizer but I love theme its pretty and plays music while flashing.

» How to load the cso/iso's?

If ill be updatng my psp from 1.5 to that custom firmware, could anyone tell me,... How do i run the cso/isos?

cause in the vid i see the person just loads them under game, but how would that be on the memstick?

i am not into the custom firmware stuff, so this might be a really nooby question, but i'd hope anyone can help me.

Thanks. Escudo

Re: gfhfhfj (Unregistered) - 2006-10-25

» dgh

just put them on X:/ISO and run them from the XMB Game Menu! its very easy

by JohnnyC (Unregistered) - 2006-10-25

» to mike

if you were runnin version a before you bricked your psp just run recovery mode and reflash 1.5 to unbrick it

by JohnnyC (Unregistered) - 2006-10-25

» to escudo

when you update to 2.71 se-b there will be a iso folder in the root of your memory stick just put them there then when you run your psp just go to game go down to memory stick and they will be there then just press x to run them

Re: Escudo (Unregistered) - 2006-10-25

» Sounds great

That just sounds freaking awesome :)

and if its uncool, you can easily downgrade back to 1.5 ;d? wooty.

think im gonna try it later on today. :D
