- PSP battery that’s at least 78% full
- Download: 5.50 GEN-B
- Disable ALL plugins.
- Back up your save files (so that if they get corrupted, you still have backups)
How to install 5.50 GEN-B CFW on your PSP:
Before you get to install 5.50 GEN-B, you need to install 5.50 GEN-A so read this guide on how to install 5.50 GEN-A first then come back here.

- Pandora (converting the battery to/from the Pandora-state) and Shutdown Device options added to the VSH menu

I Had the 5.00 m33-6 update successfully, but when i tried to upgrade it to the 5.50 GEN-a, i got to about 90% of the update and it said there was an error, couldn’t switch off normally so i took out the battery and put it back. Unfortunately it never came back on, the green light stays on for a minute and then it goes off, what do i do, someone please help me. ASAP.
Can you enter the recovery menu (Hold R button while turning the PSP on)?
Cannot update from 5.50 gen-a naar 5.50 gen-b. Get this while executing update 5.50 gen-b:
please wait, i need work…
process failed, cant load module
i had a bad flash from 5.00 m33.6 to 5.50 gen-a but someone fixed this with a pandora battery and flashed it with 5.50 gen-a.
Does anyone has an idea which module cant be loaded or why ?
thanks in advance
Sounds like you bricked it. You’re going to need a Pandora battery to fix it.
This is not new but I had to ask since I cannot find a direct answer yet. I updated to Gen B2 but yet system info still showing Gen A(Full). What did I do wrong. I am a dummy with PSP. Pls help.
can i upgrade my 5.03 M33-6 to 5.50 genB? im afraid to upgrade it because im using chickhen. =/
No you can’t. If you’re on Chickhen, your PSP isn’t hackable.
Is it necessary to upgrade to gen b-2 after gen-b?? Thanks!
Yep. Especially if you want to upgrade to 5.50 GEN-D3. Even if you don’t plan on upgrading, it’s still recommended to install the GEN B-2 patch.
After upgrading my psp to 5.50 GEN-B2 in the system information, it is still GEN-B (Full).
is it really like that??
i already upgraded my psp to 5.50 GEN A & now moving to GEN B, but all GEN B files that i got says its corrupted data… why is that? help me,, coz im trying to update my psp to GEN D3
Please check your PSP’s current firmware to confirm that you really have 5.50 GEN-A.
tnx! this forum helps me alot!
)
does this work with psp go???
Nope. The PSP Go is still unhackable.
I installed 5.50 GEN-B2 but it is still GEN-B (full) in the system version. Is it really like that?
Yep. I guess the GEN TEAM forgot to update the version number with GEN-B2 but rest assured that it was successfully installed.
thanks!

i’m trying to upgrade my psp from 5.50 GEN B to GEN-B2, when i try to update it, it said the data is corrupted. Should upgrade to GEN C then to GEN D?
No, you don’t need GEN-C to upgrade to GEN-D. The files you’ve downloaded are probably corrupted, try downloading it again.
iis it save to just transfer all downloaded files to the PSP? (overwriting it)
I got a problem. When I start the updater it said like this:
Please wait… i need work…
Done with success
Checked the version it still says : 5.50 GEN-B (Full). What should I do?
You’re installing 5.50 GEN-B2 right?
I’ve checked it. It’s the update to GEN-B2
um, i mean the answer is yes.
help naman po.. 5.50 gen-B (full) na yung PSP ko pero bat d ko po parin malaro yung Assassin’s Creed Bloodlines…??
phat PSP 1000 gamit ko…??
i have a psp with version 5.03 mhu can i put gen d3
If your PSP is hackable, yes, if not then no.
Check if your PSP is hackable by using this post: http://www.atmaxplorer.com/2009/03/how-to-check-if-your-psp-can-have-cfw-installed/
Erm, yes… I have a question… how can you confirm if you already have the GEN-B2 fix if you can only see GEN-B (FULL) in the system information? I just had my CFW updated from a shop a month or so ago, and I just recently downloaded PS:P2 and found I cannot play it with my current CFW, so I wanna upgrade to D3. I’m not sure whether I have the original GEN-B CFW or the GEN-B2 CFW.
There’s really no way to know
. You can however run the installer for GEN-B2 whether you’re still on 5.50 GEN-B or 5.50 GEN-B2 safely. It’ll simply add/overwrite files.
Okay. So just download the file 5.50_GEN_B2.zip posted from above, install like so from the instructions, download XGen updater and install GEN-D3, right? By the way, no need for the Pandora battery thing right? ‘Coz I don’t have that. The shop I went to has that, and they’re the ones who installed GEN-B (Full) into my PSP. That shop’s pretty far from where I’m living though.
Erm, in addition to my previous post, I won’t need an internet connection while doing the updating as well, right?
Yep you just need to download the file above
. And yes no need for a pandora battery 
Cool, had it working now. Pretty nifty too, this updater. I won’t need to journey to a PSP shop just to have a firmware updated. I can just stay home, download and install. Kudos to the developer.
I recently upgraded from 5.00 m33-6 to 5.50 GEN A. My problem is that my select button on my psp is broken and it just keeps pressing. When I was on 5.00 m33-6, I disabled vsh menu because my psp won’t respond the buttons. Then when I upgraded to 5.50 GEN A, I couldn’t disable the vsh menu. So, I can’t access my XMB or the psp. I can only access the “Recovery” mode. Is there another way to run the upgrade without going into the XMB? Please Help Thanks!
prolly thru a pandora battery but you should get that fixed

Just run the installer for 5.50 GEN-D3 again if you want to revert to it.
