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

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!

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
Hi, can I go straight from 3.71 to 5.50? thanks!
Yep but it takes a while. It’ll be much faster (provided you already have every thing you need) to jump from 3.71 to 4.01 to 5.00 to 5.50.
Hi, it’s my friend who has a 3.71, but what I was trying to upgrade yesterday was my unit which has 5.00 and I wasn’t successful the upgrader seems to be not working or is it just that long? help me please. thanks so much.
Hi, I still can’t seem to complete the upgrader process. I’m running on 5.00, please I need asssistance.. thank you.
Hmmm I’m thinking that the problem might be the GEN-A files for you (which is weird since some people got it to work). Have you tried all the links? I’ll try to reupload it and update the links.
does this firm ware run CTF files themes…cuz they’re rely cool!!!
Hi, i recently updated and went from
CFW 5.00 M33-6 to CFW 5.50 GEN A/B.
Everything is fine except when i try to access the PlaystationStore or Internet Browser it pops up a blue screen saying:
“Setting Information if corrupted. Press the O button to repair and restore default settings.”
But when i press O nothing happens and it just shuts down. Please Help!!
^_^
If I upgrade my PSP from 5.00 M33 to 5.50 Gen A can I still use my PSP to play classic Emulator like SEGA GENESIS Nintendo and SNES?
Yep. From what I’ve seen and experienced, only POPS experiences problems with 5.50
