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 | 5.50 GEN-A | 5.50 GEN-A
- Disable ALL plugins.

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.

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.

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.

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?

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.
