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.
Update: This guide is sorely outdated. If you please refer to this new guide instead : Install Signed 5.03 Hen + 5.03 GEN-C on your PSP.
Important UPDATE: If you are having trouble playing the latest PSP Games, you may want to install the Prometheus-4 module or use the ISO Tool Patching guide. OR you may want to update to 5.50 GEN-D3 
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)
How to Install Custom Firmware 5.03 GEN-C for ChickHEN
Before you proceed to installing custom firmware 5.03 GEN-C, you need to install ChickHen R2 on your PSP first. Just click the picture on the right to install ChickHen R2 and comeback here to finish the installation.
How to Install 5.03 GEN-C

- After all process is complete, press X. Your PSP will reboot.
- Congratulations, you’ve just installed 5.03 GEN-C.
Important Note: If this is NOT the first time that you’ll be install 5.03 GEN-C (meaning you accidentally turned off your PSP and had to reload 5.03 GEN-C again), hold the L trigger (Left shoulder button) when running the updater.

Try reinstalling 5.03 GEN-C. That sounds like a bad flash.

Bale to run the games on your memory stick, you need:
1. Chickhen Running on your PSP
2. 5.03 GEN-C installed over ChickHen.
This guide pretty much explains what you need to do to (re)install Chickhen and 5.03 GEN-C
can u tell me what to do? im new to this kind kz…
Everything you have to do is already written in the blog entry. You may be new to PSP scene, but you’re not new to reading.
Thanks for that
No prob sylv3r, I’ve learned a LOT from this blog and its very easy instructions. Keep up the good work Master!
my psp version 5.03(before)….i update it to 5.55 and i cant play my download games…..what should i do???
You can update your PSP to 6.20 and install 6.20 TN-D or 6.35 and install 6.35 Pro-B3.
my psp ver.(5.03)before and i update it to 5.55 and i update it again in ver.6.37 and i cant play my download games………………what shoul i do?
You upgraded to 6.37. At that point the only thing you’ll be able to do with your PSP is run some homebrew but no ISO games.
wala na pu bang solution…
so far wala pa. 6.37 lang ang tanging firmware na walang ISO support.
pwede nyo pa install yung sinasabinh chicken sa mga nag aayos ng psp, or download kayo sa youtube ng video how? then download nyo din yung files na chickhen, meron akong files kaso paano ko mabibigay sayo..??? email with attachment?
Sir patulong nman.Ung psp k kc inupgrade nung kasama k d2 original sya 5.03 tpos nging 5.03 genc full.kso ayaw maplay ng iso games naki2ta k ung games dun s games icon kso pag click k may error message n lumalabas.”the game could not be started (80020321)”Tnx!
Install the latest add-in, Prometheus-3 v2 for 5.03 GEN-C. It’s also in this blog.
Is it theoretically possible to directly install 5.03 GEN-C to a PSP-2000 with CFW 3.90 M33-3?
hey all,can i just install 5.03 gen C on a psp 3000 without 5.03 gen A or B???help2…
Yep. You can go straight to 5.03 GEN-C
Hi Sylverblade. Just wondering if there’s any update on Prometheus cause I just downloaded Parasite Eve 3rd b-day and i cant run it. Thanks ! ^_^
Pa-help nman pls.. I have psp 2006. 5.03 gen c ang Custom firmware nya… ngrestart ung psp ko. ang problema, gnamit kong pang-load ng Chicken ung sa friend ko n may psp 2000 n 5.00 m33 ang version ng psp nya.
Ngload nman ung chicken pro d na ako makapaglaro ng tekken 6. tpos tiningnan ko ung version ng psp ko, ngtaka ako kc 5.00 m33 na sya… 5.03 genc nging 5.00 m33.
anu po pwedeng gawin ko pra maibalik ko sa 5.03 gen c ulit un? Tnx. pls..
Most likely pinalitan nya ung loaded CFW from 5.03 GEN-C to Custom Firmware Enabler (which will pop 5.00 M33-6 when you look at the firmware version). Just follow the instructions on this page to restore 5.03 GEN-C or for simplicity, follow the other guide to install Signed 5.03 GEN-C.
@ sylv3rblade
Thank you for the reply.. I appreciate it too much… pero now 5.03 promentus n cya, ngtry lng ako pro ok nman as of now.. tnx
I have a PSP 3000 with 5.03 OFW ChickHEN R2 and 5.03 GEN-A (Full). I want to update to 5.03 GEN-C but my question is if i have to install first 5.03 GEN-B to make it possible. Or go directly to 5.03 GEN-C update, and after Prometeus Patch.
Hi sylv3rblade,
I have a problem when trying to put my iso/cso (games) inside my memory stick,
b’cos after I install the Gen-C (full), my F: drive become a zip folder. I can’t copy any games into the memory stick(I check my system setting it show that GEN-C (full). Sorry for the nood quetions)
Thanks.
Hi YTS,
I’m not sure I understand the problem. Your PC reads your PSP’s storage as a zip folder? Have you tried accessing your PSP from another computer?
Hi sylv3rblade,
I already solved the problem, just change the setting from umd device to memory stick at vsh menu. but now I got another problem, when I try to copy my iso/cso file into psp/game it show corrupted data, can u give some advise.
Thanks.
Hello I have a PSP 3006 and have a System Software of 5.03 GEN-C Full. And I saw one of my classmates play ISO games on a 6.35 custom firmware. Can I still upgrade my custom firmware? He told me to uprgade it so I can play other more games (he played GOW: Ghost of Sparta that time). I am just afraid that I might not play ISO games anymore… if this is possible on my psp, can you show me a link of your tutorial on the latest firmware that can still play ISO’s?
Thanks Venn.
when i open the file corrupted data is written and it does not work
You need to have Chickhen running before installing 5.03 GEN-C
Just a quick question.
PSP-3004 TA-090v2 OFW 5.03
Before installation, the memory stick can be browsed (can see the ISO, PSP, MUSIC, PICTURE folders).
However, after installing 5.03 gen-c, all I can get when connecting the USB are 3 folders namely dic, font and vsh…
Any ideas as to this? And the media size that registers in my computer is only 40MB as opposed to what my memory stick capacity is (4GB).
Please advise.
You have probably mounted your PSP’s flash memory. That’s dangerous since if you write/delete anything on that partition, it’ll brick your PSP.
Press select to access the VSH menu. Look for a setting that says “USB Device” and change it to “Memory Stick”
Thanks man… Good thing I haven’t done anything to that partition…
i have black psp 3000 and installed chickhen and gen c and have been playing games for a while now but suddenly my systerm started running very slow and sometimes cant even load any ting. what happened to my psp and is there a way out.
need help…modified na to psp ko b4 accidentaly na reformat ng ate ko..prblma ko now gsto ko ako mag modify n2 pro dku sure kasi psp2007 model eto..possible ba eto e modify?
What is your current firmware version? This may help.
Hi sylv3rblade,
I installed as instructed (HEN, GEN-C, PROMETHEUS). But my cso and iso games still aren’t appearing. Do you have any idea how to fix this?
My firmware version is 5.03. Hope you could help. Thanks.
Please check if:
Your games are in the ISO folder (Memory Stick:/ISO)
Your games are in ISO/CSO format
If your PSP displays 5.03 GEN-C as above.
I realize I’m replying way too late on this but thanks! The problem was that it was located on Memory Stick:/PSP/ISO instead of Memory Stick:/ISO. (My PSP displays 5.03 Prome-3 btw) Really appreciate you answering my question.
I have another problem though. I copied files from my previously used PSP (which I just borrowed) and the save files don’t seem to work. Is there something that I might have missed?
Are your save games in the proper directory?
can u help me coz the chickHEN wont work
