True to their word, the GEN Team has now released Custom Firmware 5.03 GEN-C. It’s an update to their existing line of 5.03-based firmwares (5.03 GEN-A and 5.03 GEN-B) that will allow you to play games that require upto 6.10 without running the decrypter to patch the game.
Important Notes:
This guide is for non-hackable PSPs. (PSP-3000 / PSP-2000 TA-088v3). If you’re not sure what PSP you have, please read: Is my PSP hackable?
On this guide, we will help install 5.03 GEN-C on your PSP. There is no danger of bricking your PSP unless you deviate from the instructions listed below. Unlike custom firmware for hackable PSPs, the danger of bricking your PSP-3000 / PSP-2000 TA-088v3 is quite real. If you’re not sure about a step, take the time to post a question.
Do note that if you have official firmware 5.50 or higher installed, stop now. You can’t install the chickHen hack which means you can’t install 5.03 GEN-C.
Requirements:
- A PSP-3000 or PSP-2000 with TA-088v3 motherboard.
- A PSP with ChickHen R2 up and running
- Download: 5.03 GEN-C
- Back up your save files (so that if they get corrupted, you still have backups)

PS
I have extracted all files, redownloaded all files and still the same message appears
PLS REPLY QUICKLY!
Another PS
Sorry for having so many PSs but also when i run 5.03 GEN-C or GEN-B the stupid message appears and my psp magically turns GEN-A. This happens even when i run it directly after running CHICKhen. Bakit ganun?
PLS REPLY! My psp is version 2000 slim and is a TA-088 v3 Checked using the PSPident 0.4
help my GEn-B and GEN-C dont work. I follow all the steps but it just says: reboot your psp in CFW5.03 GEN-B/GEN-C when i run them. When i do run them, my psp just becomes a 5.03 GEN-A. My psp is a slim 2000 TA-088v3. pls help me!
PLS Reply quickly
I’ve just figured out how to do it. One thing you’ve failed to mention was that once you run the GEN-C updater, it’s going too say “Reboot your psp in CFW5.03 BEN-C” after that, you have to run the GEN-C updater again WHILE HOLDING THE L BUTTON ON THE LOADING SCREEN (when it shows the psp sony entertainment). It should take you to the GEN-C menu. press x to install GEN-C and press x again to reboot and then… You’ve just installed GEN-C!
I hope this helps you and all the people having the same problem! Btw pinoy rin ako
Will update the post to reflect this
Thanks.

Inside the ISO folder at the root of your memory stick, if you can’t find one, create an ISO folder and drop your files there.

help i have downloaded PES 2010 and wen i try to start the game, it shows the error message “could not start the game”……pls tell me wat shud i do?? i have the GEN-C
same here hakusho, silverblade plz help us what to do.
pano if bigla nwla ung mga games ko sa psp uhm my psp is 3000 version 5.03 GEN-C??? UMD nlng ba pde d2?
erm… ihave a problem. i’ve downloaded the gen c file and successfully hacked the psp to gen c. the system settings read “5.03 GEN – C (Full)” but the game files i put in the ISO dont appear in the psp when i turn it on… help?
My psp is a 3000 btw.
What file format are your games and are you certain that the directory you’re putting them in is X:/ISO not X:/PSP/ISO?
the games are in rar format. other games in rar format can be played on my psp so i dont find the format a problem. and yes im sure ive put the games in the ISO folder, not PSP/ISO
in rar? Do the files specifically end in .rar?
the type of file states winrar archive
They need to have the extensions below (.iso or .cso) in order for them to work.

but i have a few games that are also in the rar format that works..
Winrar actually calls all files that it opens as a winrar archive so there’s really no other way of knowing other than checking the extension.
ermm… do i update the psp 3000 to gen c after the psp reads “5.03 gen-b (full)” or reads “Chickhen r2″? :l
i have downloaded PES 2010 but its not running on my psp. i have tried it even on gen-a but it still wont run. plz help!!
If I turn the psp off can I upgrade directly to C or do I have to update to A then B then C??
Thanks!
You can install 5.03 GEN-C directly
