Custom Firmware 3.71-M33 Released!

greg | September 23, 2007

I just shit my pants… After much drama Team M33 has finally decided to release their new custom firmware — 3.71 M33! Get it while it’s hot folks!

Just to be clear — please make yourself aware that 1.50 kernel enabled homebrew WILL NOT WORK with 3.71 M33, yet… As mentioned below, “the main installer will not install 1.50 kernel anymore. A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 will be released in a few days (for fat only)”.

3.71-M33 changes:

  • Now uses 3.71
  • VSH Menu is not longer launched using HOME key, but using SELECT now. This is to not interfere with the XMB function of home, which is now more useful in this firmware.
  • Psp Slim: umdcache was allocating memory even when homebrew was launched, wasting memory that homebrew programs may want to use. Now umdcache module is stopped before it can allocate any memory, only in the case homebrew is launched. Also, memory is unprotected for user memory usage by M33 core (only when homebrew is launched). Developer, for a sample of how to use the extra memory, see the extra ram sample of the M33 sdk.
  • Both version boot now from 3.XX ipl, and are independent of 1.50.
  • The main installer will not install 1.50 kernel anymore. A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 will be released in a few days (for fat only)
  • Note: due to some changes in kernel nids by Sony, you can expect a lot of kernel plugins not working anymore. Programmers: refer to the sdk readme for details.

Installation requirements: A fat PSP with 3.52 M33-3 or 3.52 M33-4. Previous versions of M33 won’t work, due to a bug that affects them and OE; or a PSP Slim with 3.60-M33. Instructions can be found in the always important readme.txt. Resort to our forums should you encounter problems or difficulties.

No time for chit-chat, must go install. Enjoy!

Huge props to Team M33, Dark_AleX, and everyone else involved with the development of custom firmwares.

Download:
CFW 3.71-M33
FW 3.71 Update EBOOT

P.S. I found this interesting: on Team M33’s site, it’s stated, “M33 == Dark_AleX.” Also, dark-alex.org now points to M33’s site. Could it be?! Yes, of course it is!

Thanks for the heads up, EvilSeph

3.71 M33 will be the last release from DA aka M33

Comment by Darius Sinclair™
2007-09-23 22:01:01

I bet we can expect another AKA from DA. He’ll pop up again somewhere else. First Spain, then Russia, next… Let’s wait and see.

Dark_Alex has also confirmed that he is the M33 team and has told MaxConsole exclusively he decided to reveal his secret identity because it is one of his last releases as he has gone as far as possible with PSP custom firmware.

don’t tell me you didn’t see this coming,
i mean darkalex announces that he’s leaving the scene and then out of nowhere appears a “team” equally talented in developing cfw and picks up from where da stopped.

Comment by Aures
2007-09-24 11:12:59

But after a couple of M33’s interviews, especially when said “Hey, DAX, if you’re reading this, we expect you to contact us at this [email]“, everybody forgot about the DAX=M33 hypothesis.

There is one slight over looked text issue. When changing from the 1.50 kernel to 3.71 kernel in the recovery the text still says 3.52 not 3.71 under.

Hey, heres a thing that i don’t understand :/
it says it requires a Fat ass PSP, but there it uses the 1.50 kernel etc…
But i can’t see any connection to the 3.71 on a Slim, more on the Fat ass…
Is the 3.71 M33 also on the fat ass PSP?

2007-09-23 16:58:34

Wow, thanks DA/M33.

On another note, this “scene” has gotten bloody hilarious..all that drama during the ps3news vs scene …lets hope Team Wildcard and that other team (AoP?) can meet up with the standards set by DA, our beloved PSP God working in the shadows

I’m pissed off with some of you lot thinking it’s Dark Alex. IT PROBABLY ISN’T! Stop f*****g giving someone credit that is likely to have nothing to do with it, the coding is totally different. Besides even if it was, YOU and I do not know so act grown up and don’t keep praising Alex until you got proof. Anyone could do this if they had the skill and time.
He said he didn’t want to do this constantly because (basically) he wanted an outside life, most of you who are adamant it’s him are basically saying that’s all he does. Shame on you.

how the fuck do you know the coding is totally different? did you compare both source codes (OE - M33)?

quit the crap! seriously!!

2007-09-23 22:06:29

I would praise DA even if he took a shit on my front lawn. He pretty much kept the scene alive and gave people hope that all firmwares could be hacked. If DA is M33 then its all good to me.

Some of you really are idiots. I never said he didn’t and I think he did a great job. Maybe it’s you who needs to read before commenting. Fool. I just think you aught to be grateful that someone is doing this for big noses such as yourself so shut the hell up.

Comment by DarkKnight666
2007-09-24 12:44:27

Use Pandora’s Battery buddy, it is probably the only way to downgrade to 1.50 and then install 3.52 M33 and the 4th update, then you can update to 3.71 M33, but I suggest to stay at 3.52 M33-4 for the time being…

I can’t help but think that if d_a were involved, Us Fatties wouldn’t be left without our 1.5 kernel - especially after a break like that.
Next thng you know there’ll be a post tomorrow saying the addon is finished and working but won’t be out until October, because they want to go on vacation.

Comment by lpopman
2007-09-24 05:02:46

To get wlan working, just power down completely, remove the battery and power cord, reconnect power and battery then switch on your psp.

If your battery is a pandora, you might want to leave it disconnected.

PS I am typing this message on my psp 3.71M33 so my wlan is working.

Comment by Dark Alex == M33 || Dark Alex != M33
2007-09-23 18:10:02

Nice to see a new Custom Firmware release (I’m still using 3.40OE though) and this who’s Dark Alex soap opera is pretty damn hilarious. :) The man created a myth around his person, not bad. :P I for myself don’t know what to believe, on one hand I have no problems to believe DA=M33 as they released the next CFW’s pretty fast after DA’s departure, on the other hand DA’s releases had higher quality (for me at least, not meant to diss M33’s work!) so it is equally possible DA != M33. In either case, thanks for releasing the Firmwares, without them I could not code for my PSP and the whole PSP scene would be boring. So whoever created this FW, mad props and somehow I’m sure it won’t be the last released CFW. At least I hope so! :)

so you work for sony eh.
just get the soucre code from SCEJ & give it to M33.

i bricked my psp when trying to put my old opening_plugin.rco files on my 3.71 M33.
So im looking for pandora’s battery in the South west of the UK (mostly west devon). e-mail me @ mattomcorp@googlemail.com if you got pandora’s battery & live in devon.

You are brilliant DAX! But what about ‘Team M33′ working with team wildcard? What was that whole sourcecode story about then? And are we forgetting something, everybody who has ever cussed team M33 for not being Dark-alex, look atyourself now fools.. though you should never do that anyway.. a CFW maker is still dedicating it’s time to the scene.

Comment by Minotaur
2007-09-23 18:56:23

Surely a custom firmware without 1.50 homebrew support built-in really implies that it’s purpose is for piracy? M33’s arguments about “unlocking” the PSP don’t really stand up unless they do it themselves…

Comment by chuckstudios
2007-09-23 21:07:24

They include an SDK for 3.71 so that homebrew developers can use 3.71’s kernel.

Another thing, M33 == Dark_AleX could imply that M33 has b
