While everyone’s still waiting for a Dark Alex release his version of 5.50 custom firmware, PSP GEN has managed to release their 5.50 GEN-A Custom Firmware. Do note that the earlier 5.03 GEN-A via ChickHEN hack release is for PSP-3000 / PSP-2000 TA088v3. This version of 5.50 GEN-A is for PSP-1000 / non-TA088v3 PSP-2000′s.
Important: DO NOT attempt to install this on PSP-3000 / PSP-2000 TA088v3. YOU WILL BRICK YOUR PSP IF YOU DO.
Update: If you want an easy way to upgrade to 5.50 GEN-A and it’s successive updates ( 5.50 GEN-A -> 5.50 GEN-B -> 5.50 GEN-B2 -> 5.50 GEN-D ), you may want to look at Yoshiro’s XGen Updater.
Requirements:
- PSP Phat or PSP Slim with 3.52 M33 or higher. If you don’t have custom firmware yet, READ: Convert your PSP to custom firmware.
- PSP battery that’s at least 78% full
- Download: 5.50 GEN-A
- Disable ALL plugins.
- Back up your save files (so that if they get corrupted, you still have backups)
How to install 5.50 GEN-A CFW on your PSP:
- Extract the 5.50 GEN-A files to your computer.
- Copy the PSP folder to your PSP’s memory stick. (Yes, just drag the whole folder there)
- Run 5.50 UPDATE from under Game on your PSP’s XMB
- After all process is complete, press X. Your PSP will reboot.
- Congratulations, you’ve just installed 5.50 GEN-A
Important Notes:
What do I get with Custom firmware 5.50GEN-A?
- All functions of the official 5.50 firmware
- The [Information Board] has been added under [PlayStation Network]
- Support for Internet security service provided by Trend Micro has been added to [Internet Browser]
- An icon for built-in Internet Search has been added to the menu bar of your browser
- Option to search for the game title on Google.
- It is now possible to see an additional level of hierarchy under [Photo] [Music] and [Video]
PS3 owners are already familiar with this feature. It displays news and updates from SCEE in the upper right corner of the screen. You can now obtain information about the games ahead of the new content available on the Playstation Store, and other news from your PSP even if you are connected to WiFi.
End Micro Web Security: use technology to block access to malicious sites that can steal personal information and confidential -
Trend Micro Kid’s Safety: You can block access to websites with inappropriate content.Instead of having to point your browser to Google then search, you can do your searches directly on your XMB.
By selecting the icon of the game and then pressing triangle and selecting running Internet Search, you get to search for sites using the name of the game.
- Launch of UMDs to ISOs to CSOs and demos require firmware 5.02 or below
- Launch homebrews
- Launch of PS1 games (converted to PSP)
- Access to Recovery mode (adjusts the processor speed of the PSP, FLASH access, use plug-ins etc.).
Hat off to PSP GEN for 5.50 GEN-A.

Hello…Can I install this om my PSP-2004?
I have CFW 5.00 M33-6
Can I update?
If I updated mine will my game saves be corrupted or not???
TY in advance!
Just back up your savefiles before you proceed. It’s just copy + paste anyway.
can i install this on my psp 2006 with 5.50 ofw?will it brick my psp .plzzzz….reply.
check the CFW compatibility guide to see what PSP-2000 motherboard that you have.
If you have a non-TA088v3 PSP-2000, then you just have to downgrade via Magic Memory Stick, if you have a TA088v3 PSP-2000 then that’s a no.
I upgraded my CFW from 3.90 M-33 to 5.50 GEN-A.Then when i tried to load my saved games, some of them are corrupted like NBA live 09 and NFS underground..What should I do?Thanks in advance
As ziedrich said, just use the tool he posted. I’ll edit my posts to include it.
@Ron

can i install this on psp 1000 with version 5.50? plz reply
OFW? Read How to install custom firmware to get you started on the update.
my psp2001 has cfw 5.00 m33-6, but it won’t play videos from the psn and I can not access the playstion store with my psp. will the cfw 5.50 gen-a fix the problem? please help!!!
Try playing those videos on your PC to see if they work. Something tells me that the videos didn’t download properly.
I tried them on the computer and they work fine and they play fine on my ps3. I still can’t get to the playstation store. It keeps telling me that I have to update my firmware, which of course I don’t want to do. Any more suggestions. Will the cfw 5.50 gen-a fix this?
on the video. Hmm.. that’s weird.
In anycase, yes, 5.50 Gen-A will fix your PS Store problems.
Hi there anyone can help me with this XMB how can i enable it on my PSP 5.50. bec. i did not see such option ion my PSP 5.50….
What kind of PSP do you have?
hi i have cfw 5.00 m33-6 i update it into 5.50 Gen-A it is working good??
i have a psp phat/fat it is woking fine if i install a 5.50 GEN-A cfw and i just want know if 5.50 GEN-A is need a fast loader for iso?
5.50 Gen-A loads pretty much the same as previous custom firmwares. However, it will let you run games that need a 5.50 firmware version.
I Think I Know about cfw But Can I Hack My PSP slim with 5.50?
hi i have a psp phat install with cfw 5.00 m33-6.. when i load game in my psp i get a corrupted file…how do i get download game to work on my psp?
@casper513
please look at my post at the upper
it will restore your saves!!!
does it works on psp 3001 please reply big problem
No. What will work on the PSP-3000 is 5.03 GEN-A
I have a qns to ask Let’s say i installed the 5.50 GEN CFW. Can i install back the M33 CFW if Dark Alex comes out the new one? Is the procedure the same as how i install CFW M33 into my psp? Download pbp & CFW file. rename the pbp file and throw both into the update folder. Then update
Yes, you can go to DA’s CFW. You can just flash your PSP to it’s original firmware then installing CFW and upgrade all the way to DA’s latest version.
As for the steps, everything is just a single file
CAN I INSTALL IT IN MY PSP 3004 I HAVE 5.0 OFW AND HOW CAN I INSTALL CFW IN MY PSP ???????????????
Please read the whole post. It tells you if you can install or not AND what firmware version that you need.
hi sylverblade!
im new to these things but i’ve oredy red a lot about CFW etc.. i only have games on umd and now i want to have games on my memorycard i know it’s iso/cso file u put to it, i just want to know if those cfw thing works on my psp, i have psp3001 and a system software version 5.50 what is your suggestion? thank you!
Please read the guide again. At the very top, you can see it’s pointing your to custom firmware 5.03 gen-a which is for PSP 3000s. However seeing as you already have version 5.50 for your firmware, then you can’t run custom firmware. At least not yet.
i am getting pandora battery and i am wondering if you download cfw and night pr please respond if you know
i forgot to add i am getting pandora battery and i am wondering if you download cfw and night pr please respond if you know for hacking
i can’t play the game from my memory stick, can you help my problem?
I have a psp PHAT that has sony’s 5.51 is there anything that i can do to get custom firmware. If so how? Also I don’t have access to an already modified psp and the computer I have runs windows 98 so that limits programs that i can run. Please don’t bash me I know my computer sucks. Any help is welcome, and I need it.
I also have a psp SLIM but I am unsure which motherboard it is. The serial code starts in HU0 and the guide mentioned HU2 not sure if this is the same or not. But the firmware on that one is sony’s 3.80. Combine that with my previous post and you have my question. Can I run custom firmware on either of these systems. Oh and the slim has no screen so i’d be doing anything blind. But my brother has a working slim with the same specs as mine but his serial begins with HU1. Any suggestions?
When will Dark Alex release his version of 5.50 custom firmware
Yeah same question as above.When will the 5.50 custom firmware to downgrade PSP-3000 / PSP-2000 TA088v3 be out. I’m using psp 2006 with the TA088v3 board. Hopefully u guys can make it soon.Thanks a lot man.
i installed ver 5.5 on my psp but still i cant play resistance online
mr. sylv3rblade.. i already installed a popsloader that is working fine in a 5.00 m33 – 6..in fact i already using it..
my first question is can i update to 5.50 gen – A if my current firmware is 5.00 m33-6?
and if i can update..do i have to update my popsloader??
note:on a site (psphacks.com) i’ve read that there is a popsloader for 5.50 gen-a…do i have to install this if i can update to 5.50gen-a? or my current popsloader will work fine to 5.50gen-a…
The rationale is that when you upgrade your firmware, you also need to upgrade your POPSLoader to prevent any conflicts.
hi sylv3rblade i have a fat psp 1000 running cfw 5.00m33-6 if i try to update to 5.50gen-A will it install properly and work, cause im scared that it will brick my psp
I HAVE INSTALLED THE 5.50-A ON MY PSP COZ BUT STILL I CANT SIGN IN AT PSN. WHAT SHOULD I DO? HOW DO I KNOW IF I HAD INSTALLED PROPERLY VER 5.5 COZ I FOUND OUT THAT I WASNT ABLE TO DISABLE MY PLUGIN WHEN I INSTALLED THE VER 5.5 GEN A. CAN I REINSTALL? PLS REPLY
ei mr sylv3rblade..
i update my cfw to 5.50 gen-a but in my opinion it still needs to improve..there are some bugs that i noticed so i decided to switch back again to DA’s M33 cfw..
my question is how can i do that?
is it possible to switch directly from 5.50 GEN-A to 5.00 M33(the old method DL 5.00pbp then put in update folder blah blah blah..)is that it?

can any one tell is there firmware for psp 3004 pb i need thanks
5.50 gen-a/b SUCK.
Good luck getting gpsp and snes9xtyl to work.
I upgraded from 5.00 m33-6 and they broke, i pandora’d back to 5.00 m33-6. Don’t waste your time til they fix the incompatibilites
those emulators still work fine to me……and there’s also new release..5.50 GEN-B
special feature is u can make ur own pandora battery via VSH menu
thanks for the heads up. Updated with a new post
Hello guys, sorry for the post. today i buy the PSP 3004 5.50, and im looking to hack it to play ISO and CSO games, does this FW make it possible to play the games?
5.50 GEN-A cannot be installed on a PSP-3000 not even the ChickHen will help you atm.
Thx bro for the replay. Gona go to the store and ask my money back and try to find one that will work with ChickHEN
Hi, I have downloaded the official firmware version of 5.50 and I’m just wondering what will I do in order for me to play the games without the UMDs? I’m still new with this stuff.
@…Curious Player…
Too bad you shouldn’t update cause there’s no ChickHen for 5.50 ofw (for now)
and Dark Alex hasn’t made a 5.50 M33 so i’m stickin’ to Gen-B
can i install this when i have a “5.50″ version?
@DNaNGeL619
What do you mean??
5.50 official firmware(ofw)??? for OfW you can’t for now
technically that’s only half right. Hackable PSPs can still be downgraded with pandora
off topic, does anyone know if it is easy to change the covers of a PSP Slim?
I used this guide to replace my old PSP’s faceplate.
Be careful with those screws. They’re SO easy to lose.
So…That’s a relief…then Pandoras can still be used…….So Hellcat’s Recovery Flasher is useless if it’s not Hombrew Enabled..like ChickHen not compatible to 5.50 OFW..
Hi, I’m not familiar w/ PSP at all, just trying to make my 7yr-old’s PSP-1007 (w/ 3.52 M33-2) to play Transformers-Revenge of the Fallen. It needs 5.50, but then I got the “DADADADA…” msg while trying to update from the UMD. So after a few hrs of browsing the net I thought my best option was to install CFW 5.50. Now I got “This program requires 3.53 M33-2 or higher”, so I’m stuck again. Thanks for any help!
Actually, the msg was “This program requires 3.53 M33-3 or higher”.
start updating from 5.00 M33
Hi, I updated to 3.52M33-4, then 3.8M33, then 5.00M33, then 5.50GEN-A, finally 5.50GEN-B. Transformers-Revenge of the Fallen is working now! Your help was very much appreciated!
congrats
enjoy your cfw-ed PSP
its the first time i am trying to install cfw and i have ofw 5.03…i used chickhen r2 and after it loaded i tried to install this cfw but i get a error loading degeneration …. any clue what i can do about it (no pandora solutions pls)
Install Custom Firmware without Pandora Battery
hi,i have psp 1000 and installed 5.50 how can i install GEN-a .when i try it massege come “the game could not be started. error has been occurd” please replay me.
thank you
The guide SPECIFICALLY says your PSP must be running custom firmware before running this installation.
Follow this guide instead
sir,there are any m33 ver. available for 5.50 or 5.51. if it available please replay me link.
how to download custom firmware???? for 5.50.i wanna run iso file in psp anyway.
mr. sylv3rblade i got a PSP 2006 with a TA088v3 board and 5.50 ofw…I cant do anything with it now…. I am trying to downgrade it but cant …PLZ help me….
There’s currently no way for you to downgrade a TA088v3-equipped PSP.
dude you gots to know what psp you have and what it can do a 2006 is just like a 3000 that’s why before even hacking your psp learn more about it and get help first from hackers and other people that know alot about hacking and psp OFW and CFW
OK this is good info but the info im looking for is can i still download ISO/CSO’s not from PlayStation store I mean can i still download ISO/CSO from other sites plz reply to this cause i think theres something going on with this GEN A and B?!?
5.50 GEN-A/B will let you access the PSN Store. I’m not sure how long this will stay true as Sony’s looking to release 5.55 OFW soon.
hi sylv3rblade i have a psp slim running cfw 5.00m33-6 mobo TA-085 v1 i’ve try update to 5.50gen-A and don’t work, my psp brick. i’ve ben try for 5 n brick again, any clue for this??
right now still use cfw 5.00m33-6
hey.when i try to run the update,it says “This game cannot be started.The data is corrupted”
Do you have custom firmware installed before running the update?
sorry, but how to u disable plugins
Turn off your PSP then turn it on while holding the R Trigger to enter the Recovery menu. From there go to plugins and disable everything.
Mine worked beautifully, thank you!!
ya i finally figured it out i had to downgrade my psp lolz thx anyways i’ll try this after i have downgraded my psp (which i already did just now) thanks.Peace Out!
hey can i update my psp to 5.50 gen a straight from 5.00 m33? or do i have to go to 5.00 m33 2, m33 3, m33 4, m33 5, m33 6 before i get to go to gen a?
yes you can go straight to 5.50 gen-a
tnx =D
hey, if i get this update, will i still be able to play all my old ISO/CSO games i’ve downloaded?
also, if they come out with a new M33 firmware, will i be able to upgrade to that after i have this new 5.50 gen-a?
Yep, you will still be able to play your UMD games. However, bear in mind that there are current games that block custom firmware and can only be played if you install the latest official firmware.
You can read more on that here:PSP Games that block custom firmware
ok if i was you i would run the new m33 and if you not sure and you think its scam send your m33 download to me so i can see if it is realy a m33 instead of a one of them fakes that sony put out there but if you want to install GEN you will need Custom FIrmware is what i hered but yes i would get custom firmware and IDK if you can put it to 5.50m33 it deppends if its the same firmware or a little bit under but i I know if you have the same firmware so yes you can put it to m33 or Gen like if you have 5.50 GEN you can put it to 5.50m33 if it came out…..send me more info so i can help more
DA has not yet expressed interest in updating his latest release which is why we still don’t see a 5.50 M33.
If you see a 5.50 M33 installer floating around somewhere don’t install it. It’s a fake and will likely brick your PSP.
i have a psp-1000 which is on fireware 5.50 M33-3 and try putting 5.50 Gen but it isn`t working because i keep getting corrupted data/file.
do u have an answer to this? Thx for reading!
never mind thx
i have a psp 2000 running on 5.03 m33-6. can i upgrade it to 5.50 gen-a?
umm.. are you sure it’s 5.03 M33-6? o_O
How would I uninstall the custom firmware so that I could run the update?
Just install it over what firmware you already have.
i have a psp2001 – slim w/ CFW 5.00 m33-6. i have been using DA’s cfw since his first release.. but would like to try this one out. will this work on my psp model?..
Yes it will.
ok, will try it out. but can i revert back to m33 if ever?…
Yep. If you decide to go back to 5.00 M33, just follow this guide. Specifically working the Hellcat’s Recovery. That’s all you need.

hey, i need help accessing the recovery meau, when i updated to 5.50 Gen B i couldn`t access it, do u know any solutions to this problem, or to i have to dowgrade back to 5.00M33?
If he has a 4 GB sandisk MS (Probably does) then he should use a smaller MS, like 2 GB. The same thing happened to my bro and I let him use my 2 GB sandisk memstick to upgrade and it worked fine.
I have same problem ..did you find a fix for it…
how long should the update take because ive been waiting for about 20 minutes
it only should take 5 minutes
Hi, I’m trying to update now and I have the same problem as moleman.. the updater is taking a long time to finish.. is this really how it works? thanks!
The installer probably encountered a problem. This is usually the case if you were upgrading from firmware lower than 5.00
