Custom Firmware 4.01 M33-2 and 1.50 Kernel Add-on Released
greg | June 29, 2008
Concluding our action-packed custom firmware adventure is the promised 1.50 kernel add-on for PSP Fat owners. And in addition to that — Dark_AleX has corrected a few 4.01 M33 bugs; ergo, releasing 4.01 M33-2.
Custom Firmware 4.01 M33-2 changes:
- Nids resolver: Fixed scePowerGetCpuClockFrequency issue. This is the same bug that happened in 3.80 M33-1, it won’t happen again.
- Fixes recovery problems that have appeared in prior version (incorrect position of back string in language others than English, enable, and disabled strings not translated in plugins, hide pic0+pic1 couldn’t be changed, language file in flash1 wasn’t working…)
- Spanish recovery translation typos fixed.
Get down.

Hells yea!
1.50 Kernel Add-on for 4.01 M33 works on 4.01 M33-2???
yes
1.50 Kernel Add-on for 4.01 M33 works on 4.01 M33-2??? yes, sure.
But doesnt work on psp slim :(
use the “timemachine_0.1″ and you will have a complete working 1.5 firmware working on your slim… running from ms so it dosent efect the flash
i use it ONLY for pimpstreamer becoes of the damn laggy “buggy” way it plays in slims !
Im on 3.71 M33-4
Can I upgrade straight to 4.01 m33 or do I need to upgrade to a lower number first?
You can upgrade straight to 4.01
just WOW … and this time i mean it…
Hey how do i access in XMB Recovery or Savestate?
Any word on whether or not the popsloader from 3.90 M33 works?
it does work
HOW DO I ACCESS IN-XMB RECOVERY!
Not completed nor is savestate, calmdown guys
Where do I put the 1.5 Eboot to get the 1.5 Kernal working with the new 4.01 CFW?
I believe in the root of the MS.
My 8Gig memory card doesn´t work anymore :-(, Do I have to reformat it?
u can use the old “fix” from dark alex ..
i think :D
8GB memory stick support on any CFW
http://dl.qj.net/8GB-memory-stick-support-on-any-CFW-PSP-Homebrew-Applications/pg/12/fid/15908/catid/151
DO NOT USE the FATMS371.prx patch or i would assume ANY 3.xx patch on 4.xx you will brick.
damn that was fast!!!
Can someone please tell me what the 1.50 kernel add-on allows me to do on a PHAT?
I do currently have the new CFW 4.01 M33-2
Thanks so much!
for example … it runs pimpstreamer perfectly without lag…. the kernel3 does not…
Some apps can only be run on 1.50 kernel.
u lose korean fonts and LocationFree Player when u install 1.50 kernel….but u get FULL support for homebrews ( i ALLWAYS isntall it…FUCK location free player)
Where do I install the 1.50 Kernel Add-on for 4.01 M33. When I updated via the network it did NOT creat a GAME4xx folder??? I don’t see it in my list of games. What am I missing.
Thanks for the help?
1.50 Kernel Add-on
To install, first download the 150.PBP and place it in the root of your memory stick (X:\150.PBP, if X is the drive letter of your PSP). Then simply copy the “150k_installer” folder to GAME and run the installer from the PSP’s Game menu.
THanks so much for the help!
in the readme DAX said to place 150k_installer folder into GAME4XX folder not GAME….im guessing 150.PBP still goes into root of mem stick?
yea… only wors for PHAT.
150.pbp in root
create Folder “Game4XX” and copy the 150k_installer to that folder… should work fine in the normal gamefolder as well.
Does anyone know if loading speed from MS is corrected or do we still need to do tha 371fastms patch?
Does the patch work on 4.01? Anyone?
I’ve heard that patch has lead to semi-bricks on 4.01m33 so I’d be careful.
Where is the save state function?
(TT-TT)
Hasn’t been intergrated by DaX yet.
hey im a noob jus upgraded to the 4.01m33 and just wondering how to get the prx and plugins working? i dont kno how to make it work… i read the readmee.. can some one help..

cheers

Pob, if you’re going to be using it to strictly use it for playing games, and homebrews, then mate, no, not really, everything you need, and and all you’ll basically need is on a 3.52m33, though i suggest you upgrade to at least 3.71m33-4.. even 3.80m33-5. I mean, usually I (and I haven’t yet) upgrade to the newest custom firmware because it’s always full of bugs, and more than likely you won’t be able to do things you’ll usually do. So just follow my advice, basically go for 3.80m33-5 if you’re wanting to update at the mo.
My bad, I usually don’t upgrade to the newest firmware*
I was wondering if somone could please help me.
I have always had my gameboots installed and working perfectly.
After upgrading from 3.90 M33 to the new 4.01 M33-2 my gameboot no longer works.
What I get now is a PSP logo with a white background, no sound, and also not the original.
I have tried to RE-INSTALL to Flash0/vsh/resource folder and it does not work. Still get the same blank screen. Can’t even seem to go back to original. I just can’t figure this out?
Any help would be greatly appreciated.
Thanks!

Best thing is to use a Pandora Battery. Google “psp malloc forum” and find it there.
what is sdk? i dont get it.. i have upgraded to 4.01m33-2 but i dont kno how to get the sdk and prx and stuff like that working?
what does it do i dont get it.. can some one help plz?
if i put the m33-2 update and 4.01 OFW in my memstick, will it install 4.01 m33-2?
or do i have to put the m33 update and 4.01 OFW in the memstick then update to 4.01 m33, then update to 4.01 m33-2??
what u need is a pandora battery to downgrade and then upgrade to m33 u cant just install m33 firmware over sony official firmware dude
i already have m33, i guess what i wrote is misunderstanding.
the autoupdate doesnt work for me, so i have to manually update.
i update my friends psp, and they all have CFW, but when i want to update them to 4.01 m33-2, do i have to update it to 4.01 m33 then update to 4.01 m33-2? or can i just use the 4.01 m33-2 to update from 3.90 m33-3?
You should be able to go straight to m33-2.
Save yourself a lot of trouble and (if you’re running 3.80m33 or higher) let it autoupdate you to 4.01m33-2
That’s what I did.
he said it didnt work for him..
Question:
Why does DA/M33 not work for Sony?
I would guess they have tried to hire him, so is it a moral objection? (For which I would hold DA in even higher esteem than I already do) Or is Sony just REALLY stupid?
However many millions they would have to offer him, it would be well worth it…the guy plays the PSP like a violin :)
Corect me fellow PSPers if I’m wrong on this, but I believe that Dark Alex did work for Sony, but got rid of him after he was using this access to Sont tech to create the firmware’s.
You are wrong Swatmajor, he didn’t work for sony.
the guy is like 18-20 hes way too young to work for sony.
I have never clicked banner ads, but I clicked both of DAX’s on his site. Everyone else should do the same to get him a couple of bucks for all the hard work and dedication he puts into the PSP scene.
Is anyone using custom Gameboots with this new firmware successfully? Mine dissapeared after upgrading?
Thanks.
guys, if you are recieving bugs.. Report them to DAX(via his website). im sure he knows the issue with gameboots, and various others i have spotted… Prepare from M33-3 :D…
i have no prob with my slim….
Get down with the get down! DA is on it!
hi
i have 3.40 oe-a (yeah i know)
how can i update to this program?
thanks
noobi
So far I’ve seen ZERO bugs. Was running 3.90 M33-3… went to 4.01M33: Popsloader still worked. I didn’t touch it. Didn’t do anything. Just ran Metal Gear Solid right after the reboot and got killed by Sniper Wolf.
Upgraded to 4.01M33-2… again… without reconfiguring anything… Started up MGS, KILLED Sniper Wolf… Switched to disc 2…. absolutely no problem.
The google search thing worked… Recovery menu works… Fastfoward and rewine videos works…
If there’s a problem with this firmware it must be something I reaaaaaally don’t care about.
Same here. I consider myself lucky when I hear of bugs and I never experience them.
The only bug I ever seem to encounter is in MGSPO+, when occasionally, the game will appear to freeze, but is actually still going, it just LOOKS frozen. Usually happens in the loading screens, but once it happened in a timed mission, and I barely made it to the checkpoint.
Not a firmware problem though, since I have tried this on OFW (3.90) and CFW (3.90 M33 and 4.01 m33), and it does it either
I have upgraded to 4.01 M33-2 and installed the 1.50 kernel. Now XMBeditor doesn’t work. I always get the message “Error: Argument error: Image:clear([color]) zero or one argumenpú
Press start to restart”
Anyone have any ideas on how to fix this?
slim or Phat?
phat
Actually it doesnt matter… sry, but U’ll have 2 wait for the XMBeditor 4.01! Will take some time unitl its recompiled for CFW 4.01m33-2.
Well, that’s a punch in the crotch! Thanks anyway
Does this new CFW increase the popsloader compatibility? I have CFW 3.90 m33-3 and I love it. Some games might be slightly glitchy but it really works perfectly for me. Should I download this update? Will it make more PSOne games even more functional?
No, not yet. Still waitin for FF VII to run on 4.01 m33. If any1 has any ideas…
And when is the vsh/game/pops music support coming??
FF7 does in fact work perferctly on 4.01 M33. Im playing it right now for the first time no less lol. But i even read in three places it works perfectly.
It doesnt work for me!! Crashes after the new game/continue window!! Any help?? Talking about FF VII for PS1, not FFCC.
Any, ideas please…
Google “PSX on PSP compatibility list”. Follow the first link, then read about FF7.
Try different POPS versions with POPS Loader.
THX!
One thing I wish Dax could implement is another Fatsmod patch for 4.xx. I have tried the 3.8/3.9 one and it does not work. If I just ran programs (such as Gundams Battle Chronicles or Suzumiya Haruhi ) with plain 4.01m33-2 , the game intro would be very laggy. I guess it is the same issue with 3.71 jump to 3.80. Anyways, thanks for the good work Dax, nothing makes us more happier to see 5ony’s azz got whip one more time.
Ka-pow…
Does “Custom Firmware Extender v2.2″ works in this type of firmware??????
No.
hi peeps, im currently running 3.90 m33-3 and loovin it, i havent seen many pros/cons about 4.01, the only thing i miss on my 3.90 is the picodrive, has ne1 tried that on 4.01 yet??. Also, if i use my psp’s auto update function will i download DAX’s 4.01 or sonys official 1???, pleeez help, shud i bother updating??
Donno about picodrive… but u can update by using the update function. DA implemented it since 3.80m33
it’s not possible to update to sony’s official firmware if you have m33 custom firmware as it is blocked to prevent from updating to the official one..
works perfectly for me after the addon
thanx alot for replying, i just used the network update bt it sed the 401.PBP was not found, i think im gna stick to 3.90 m33-3 for a while lol. im still tryin to get a good megadrive emu if ne1 can help me out on that. THNX PSP-HACKS, AND ALL U GUYS, AN NOT 4GETTIN DAX!!!! XX
