July 17, 2006“Dual-boot” Custom Firmware
Posted by greg
Update: harleyg has released a new version of his custom firmware patch. You’ll immediately notice ‘L’ trigger no longer boots DevHook - this has been replaced with the WLAN switch. In the off position it will automatically boot DevHook upon startup; otherwise, with WLAN on, you’ll boot 1.50 normally. More useful additions have been made - below is the v0.2 feature set:
Configuration and recovery mode
- New style and menu/sub menus
- Clockspeed configuration
- USB mode
- Update vshmain.prx and recovery.elf
- Remove patch
- Launch update eboot
- Replace index.dat
Other
- No kxploit
- No corrupt icons
- No intro
Controls (while booting):
- WLAN switch down: Loads devhook
- WLAN switch up: Loads XMB
- HOLD on: Loads configuration and recovery mode
- X: Launches autoboot eboot
“README.TXT” contains a lot of useful notes - for new and current users, be sure to check that out.

Much thanks harleyg - very useful patch!
I decided to take yesterday off, fortunately there wasn’t much to report on; however, this particular release caught my attention. Harleyg has released a clever little firmware customization allowing you to easily “dual-boot” firmware versions: 1.50 and DevHook-emulated 2.xx.
Flash your 1.50 PSP with the download below. Once successfully flashed, holding the ‘L’ trigger during boot will automatically load DevHook with whatever firmware you have emulated. Otherwise your PSP will boot normally to 1.50! Cool huh?
Now, of course with flashing comes warning: DO NOT flash your PSP if you’re clueless. Any utility which writes directly to the PSP flash memory could potentially damage your PSP. You’ve been warned! Rest assure this custom firmware has been tested numerous times resulting with nothing but tears of joy.
Copy the RAR contents to your PSP’s memory stick maintaining the same directory structure. Run the customfirmware EBOOT and you’re done. As a precaution it may be wise to flash a non-custom 1.50 version, meaning if you have used Dark_AleX’s firmware or any other custom firmware, restore 1.50 to its original state and then use this.

nice work
can you undo the effects at a later date if you wish or will this stay perm?
i was looking for this cool thx
ive gotta say this is really cool and of good use to a lot of people out there…not me personally but i like the idea!
this is my 1st post but just have to say this is an exellent addition to my newly downgraded psp, this custom firmware is becoming a reality good work!!!
eh i think this could be usefull but i dont think i would use it.
#2, hold the R trigger while booting up to go into recovery mode, then press X on recovery menu, and choose remove custom firmware.
lol this is awesome because it does the exact same thing as the 100 dollar modchip in a way.
ha-ha! McZonk (author of PSPset) was working on this same EXACT thing. Guess he was too busy taking exams… you snooze, you lose!
This is SICK… MY question is:
Do you get to choose which FW it goes to from a HARD RESET or from SLEEP MODE?
I believe it would be from a HARD RESET, but IDK.
Dose this work on 2.71? can is it reversable
of course I have to flash on my psp..
only want to know if this one include a recovery elf too…someone aswer..pleeeeaze
This is great, i can leave my UMDs at home and boot any game/firmware i want from my 2GB Mem. Dual-boot just makes the deal even sweeter and faster. July has definely been the golden month of the PSP community
Yo great thing going here keep up the good work this is a huge improvement works like a charm and now like Che361 said you can leave your umds at home and boot any firmware/game onto my 4 gig memory stick duo
Awesome.
any one try it yet dunt wanna brick my PSP :(!
here is a video http://www.youtube.com/watch?v=BcYz6tyfpgI
I have a 2.01 PSP. Does this mean I finally can have the firmware 1.5 with a isoloader so I can play backups from my 1gb memory stick??
b4silence, NO, i dont know where you read anything about downgrading, however if you upgrade to 2.60, then u can use the the 2.60 downgrader, ive used that downgrader twice on my friends and it worked both times flawlessly
but anyways when i read was this thing did i thot it wuld be cool but its kinda pointless i think, cuz devhook only takes like 10 seconds to boot anways
Hey, I’m not doin it yt I’m waiting for epsilon bios, I also try to avoid flashing my psp (last time I flashed was when I downgraded my 2.0 to 1.50 that was about the 5 months ago. I caught on quick cuz that was my first action as a hacker. I downgraded the day I got it. So don’t underestimate n00bs :-). I downgraded 2 psps that day good times…So I’m waiting it out until epsilon bios come out.
not bad, but only for lazy peeps
This seems to work on modified firmware. I’d changed a lot with xflash 11 (fonts, custom startup, backgrounds, disabled network update, etc) before running this mod, and it worked fine.
Very, very good. I used with perfect results, very useful! Very easy to recover also, on start up, just hold “R” (which starts recovery/options menu) instead of “L” (which starts DevHook). Also, the fact that you dont have to go through the DevHook launcher is very nice, just straight to 2.xx firmware.
Absolutely outstanding i wish i could create thing as good as this. cheers
I’ve done it, I’m backing up RaVeN and confirming that it does work with modified 1.5 FW.
The only downside to this, is that the way it loads the emulated firmware doesn’t look natural, it takes a few seconds longer than a natural load. So you can’t fool people into thinking you have a normal 2.xx PSP by showing it start up lol
-…shadow…
finish right now…it’s so cooool..
recovery, 1.0 boot, 2.6 instead of 1.5 when booting,
no-intro screen…and all in one hb..
not bad for my first flash writing….
GHyeeaaAA!!
this seems pretty neat but I kinda need the devhook menu cause i switch from usbhost and the regular ms alot so ima wait til i know more bout this 1
Okay, this is a simple enough question, but even with all the info here it begs to be asked…if this is installed on a 1.5 PSP….does it provide THIS effect : allows the PSP to boot the 1.5 firmware as normal, allowing for homebrew / ISO loading where normally available on a regular 1.5 PSP AND booting of CUSTOM 2.xx firmware, which allows for games requiring 2.xx firmware to load off actual UMD’s in the drive / does 2.xx firmware have the onboard functionality of the 2.7 menu crossbar (web browser, etc)?????? IF NOT…WHAT is the functionality of the “custom” 2.xx firmware??
works great… big great stuff…. nice way… this rocks…

Lupin, all this does is let you load Devhook with your last used settings upon bootup instead of having to load it through the 1.5 game menu, so in effect will boot whatever firmware you set Devhook to reboot to.
so do I need to downgrade my 1.5 to 1.0 to use this or is it ment for 1.5?
Ok i tried this today and it al went fine. But after a while, i realized I didn’t need this. So i went to the recovery mode and went to remove custom firmware. However, all of my saved games aren’t loading off my memory stick anymore. They all say the data is corrupt or when i create a new save and try to save it, my psp crashes and turns off. My memory stick is fine since it still picks up all my homebrew, music, and videos. Does anyone know if this happened because i tried this custom firmware? Please help!
this is meant only for 1.50
I have a 1.50
sweet thanks aaa
does the work with 2.7
What prog do you use for getting rid of the intro screen and for the custom gameboot sounds?
When booting up straight into 2.71 USBHOSTS doesn’t work, if the last I played was through the USB it will just crash when it gets to the white PSP loading movie, it freezes just before it launches the game. And if I have played an ISO directly from the MS then it doesn’t pick up any of the ISO’s on my PC, but USBHOSTS it acknowledging that its connected to my PC, is there any way of fixing this?
you can use X-Flash
btw does anyone have any help or advice to offer for my saved game problem? I would really appreciate it.
ok nice program but how can i unflash it?? back to his orginal state
devhook have dual boot also powerbutton 5 seconds up is back to 1.50 normal up in 2.71 turns on again with 2.71 what do this program more then devhook??
@PCJUNK
boot up your psp while holding R you’ll go into recovery mode, Remove custom firmware is in there
@CHOKESLAM
saved games as in ISOs? if so, i’ve had the same problem while using Devhook, I get more free space on my memory stick mysteriously, then some of my ISOs cannot be read
the problem might be wifi because whenever i use wifi for anything, one of my ISOs gets corrupted and i have to replace it
-…shadow…
Heres a video of the newest version 0.2 http://www.youtube.com/watch?v=vEuprEIR-k0
Good work! Keep it comeing, and get some sleep! LOL
nice video blake ! but loads everything explain?
you know whatI was thinkin, there is cooler things coming out in the homebrew/hacking scene then any psp game out. If we could just get some fun games on psp there might actualy be a purpose to all of the hacks.
Do you think one day there will be a custom firmware with divx/xvid?
That would be my dream come true.
Thanks Shadow. So just replacing the ISO should make it work again?
if i use the 1.5 POC Unflasher when this custom firmware is in my psp i will go back to sony’s psp right?
wow thats effin hot!
well i used the undo poc unflasher thing and it worked
the_end_is_near
from pspbrew.com
also the hold power button wont take me to recovery mode
Ah, so this doesn’t technically make a DUAL - FIRMWARE PSP like the mod chip.
It just auto boots the DEVHOOK program from onboard the standard PSP motherboard.
Neat.
Got it. Thanks.
You have to switch the power button down to hold not literally hold the power button up.
Ok… umm so say I have a fastloader on my version 1.5… and i also have this on my psp.. when i go to version 2.7 ill be able to use internet and etc, but when i go back to 1.5 am i still able to load iso’s and etc?
reuploaded video…. http://www.youtube.com/watch?v=9VFz8FketUI there u go this should answer alot of questions…..
How did you get two UMD drives?
not only can you use this turn on your psp and start your 2.xx XMB, but you can also do it when exiting a game and going home!
umm…i was wrong lol, it only works when your in the 1.5 XMB, play a game, switch the Wlan switch off, then when you go home you go into the 2.xx, but it doesnt work the ather way around…lol
“does this work on a 2.7″ WHAT THE FU CK IS THAT??? You dont deserve to post any question like that.
“can’t load/start devhook” what did i do wrong. This is the message i get. Also, does this mean that i can upgrade back to 2.5 and this will put me in 1.5 when i wanna load iso
shadow, same happened to me when using wifi.I used that X5 web portal. First off,internet didnt work. Then when i went to load my iso, the mem stick light just flashed in a random loop. no audio/video output.Tried to delete it, but it kept coming back at 0kb. Then i had to cut and paste all my sh1t to cpu then format mem stick. has any one got onto the internet with dev hook??i have 62% signal strength with normal access point and still wont work. Has this happened with any one yet:this happens alot to me-when i plug in my ac charger,my psp will shut off!!!or other times, my charger light wont come on,or it flickers here and there then shuts off.it still works fine though,kinda strange….
pretty sweet! but i was thinkin, instead of using the buttons like the wifi switch, why dont u use the almost pointless key lock to switch, or maybe make it switch it back to 1.5 or sumthin! just a thought, keep up the good work
Ok now my Pro Evo 5 won’t work. It starts up and everything but when i try to save it just crashes and turns off. The option save loads fine because its on autosave. Anyone get problems like this? BTW i use daxziso loader for pro evo 5, not dev hook.
@JS
Yes that is what this is for.
@Bobby Digital
Try a format of the MS & reinstall DevHook.
@ Neo(the one)
No need for divx in the FW…
http://pimpware.pspstart.de/ (for network viewing)
or there’s also one (that I can’t find right now) that plays divx/xvid off of MS.
But PimpStreamer is bad ass, there’s nothing like watching anime or asian chicks w/ swords/guns anywhere I can get wifi.
@ JS again
And actually as long as your backups aren’t modified PRX’s you should be able to play them with DevHook & ditch fastloader.
But if you have modified games they may not work.
@….
I’m fine with my wifi, X5 portal works, and internet works…the only problem is IF I use wifi at all, my ISO is corrupted and I guess something gets deleted(My MS mysteriously has more freespace…)
Your problem with wifi might be because your running at 333Mhz try lowering it, thats all I can say
-…shadow…
Holy crap, this thing looks like it’s more trouble than it’s worth….too much risk of fowling things up one way or another.
I’m glad I have two PSP’s a 1.5 and a 2.7.
-Lupy
I formatted my MS and reinstalled devhook. Put my Pro Evo 5.DAX back on and it still does the same thing :(. O well i guess i just wasnt meant to play it. Time to go back to fifa…
replacing Sony’s GUI video
http://www.youtube.com/watch?v=9VFz8FketUI
ok intstalled in my 1.5 boots in to dev but freeze when i put disk in drive what am i doing wrong anyone
ok got it love this program its great now all i need is something to take me to my homebrews maybe the right button and just click the hombrews that pop up on my psp screen :D lot ideals no skills :C keep up the good work guys love ya
I can’t understanding why this update…
pressing L or R when booting already perfect for me..why I have to switch my wlan or HOLD button??
personaly I think the previous version is better so
I stay on it..
My Devhook v0.44 FW2.71 would not load properly after innstalling this mod. Neither will DAXISO that I assigned to the “x” button. Any ideas?
working fine for me, i can even load 2.71 without a UMD in drive
here is my video of Harleyg’s custom firmware patch 0.2- http://www.youtube.com/watch?v=k-yFHv62RMk
can I use the 1.50 update EBOOT for Recovery, or it must be the 2.00?
Thanks!
dose this do the same thing as wat can do wit the psp mod chip….will i have all thw stuff i have in fx 2.71
now all we need is the epsillon bios but i reckon that was fake it would have shown up by now if it wasn’t
this is an offside subject… with the DAXISO 0.62.. we need a firmware dump.. (2.xx) my question.. can it be like firmware 2.60 or does it just work with the 2.00 firmware.. because i tried to run loco roco and fifa world cup 2006 and it didnt work (both required 2.60 update)….
by the way.. good job.. works like a charm.. i like the custom firmware! :P:P:P:P
hey RICMEECH just use devhook 0.44 it can load both of those games plus it emulates firmware 2.71 so you get everything like flashplayer and stuff.
OMG!!! i think i bricked my psp all it says is cant find/load Devhook wen i take out battery everything it still says it and it flashing motion. If it is bricked is a possible way 2 unbrick a psp? if u noe plzzzzzzzzzzzz mail me sh0rt_marine@hotmail.com
they said that you need to restore your psp… recovery.. i use X-FLASH does it work? no idea.. is there another way to do it.. probably.. do i know how.. not really but thats the key.. RESTORE.. BACKUP
thanks for the tip P$PFW1.5, but i already tried with 2.60 and 2.71 and as soon as i try to load .DAX files.. the the XMB menu just freek.. and i need to reset my psp..
I use devhook full pack version 0.44 found on this website..
**** FREEZE*****
this is in reply to … with his problem of his psp shutting down when he connects the charger, good chances are you arent using the sony charger, if you are, get a new one.
also, since i am already posting, gotta love fireware editing props to everyone who makes/edits/posts these mods.
ok i dont get somthing i instald this on my psp but when i switch on my psp with the wlan swith up it is in 1.5 mode normal than i boot up with my switch down and again i get 1.5 but isnt that supposd to be 2.71???? and when i press x during bootup i again get 1.5 what doe i have to doe???? (when i boot up with hold i get to the recovery mode so taht is fine)
I didn’t like this version but I hope it will improve.
You can ONLY customize what eboot launches with x button held down. If I could customize what eboot is used for each process this would be useful.
I use irSHELL for my main boot on my emulator stick and devhook for my iso stick with the proof of concept and untill this program allows ‘customizing what boots up’ it doesn’t even live up to it’s own name.
It does however show off some very impresive features with the recovery console! This is obviously where all the work went into. Plz allow for futher customizing with use of the setup.cfg.
Im sure the inexpierenced will love this though.
It’s the best for my friend’s cuz he has no need for anything other than true 1.5 and 2.6 w/o isos.
I will NEVER sacrifice having irShell boot up on it’s own instead of this.
Irshell boots up, if i want 1.5 I quit if I want 2.6 i press x button cuz devauto is right there. And it’s just as fast if not faster.
Oh btw if i want to change my iso boot i just go one icon down and choose devhook launcher
This is all I could need. But I love your usb enabled HOLD on method.
y did i upgrade to 2.70 ….is there any hope left?
This will answer so many question about booting dual firmware http://youtube.com/watch?v=PXCsfEM9A0U&search=psp
Devhook dose not read .dax(daxziso only) files only .cso and .iso.
quick idea… dont know if anyone thought of this, in my opinion this could be kool, have dev hook, load up a coustom firmware… no flashing no notthing… …. booster…. think about it
DOESN’t WORK When You click on the icon in the psp menu it says file is corrupted!!!!!
wow dude…art….you need to get smarter its cause ur in the 2.71 load it up on the 1.5 side
dumbass
does anybody actually read the instructions?
Can anybody figure ANYTHING out by themselves?
or do dark alex and chaos zero have to create a gui setup file for everything on this site
even if they did people would still need to have someone else hold thier hand and drag them through everything
GROW A F@#KIN BRAIN GOD DAMMIT
** just a suggestion to PSP-HACKS **
howabout puting what FW the hack works for right in the the title bar of the article
For instance {”dual boot” custom firmware for 1.50 PSPs } instead of “duel boot” custom firmware
those 6 little characters (for 1.50) would probably prevent over half of the questions posted in the comments section
if u did that and kids still say is this fo 2.5 , 2.6 or the stupidest of all, is this for 2.71 then we should just shoot ourselves now cause the people who cant read but some how know how to type will never get it
somthing went wrong with mine… when i went to 1.5 it says the game could not start, besides that the 1.5 was ok… then i did try to launch 2.7 and the memory card light start to flash and flash and never starts … just remove it but i’m afraid of reinstall… anyone have any idea??? plz.
Ok i got working… i did put the SYSTEm folder on wrong place… attention NOT ON THE HOOT of memory card but on PSP… totally my mistake… i&#
