Notice that this is only for people running 5.03 or under. If you are over do not use this.
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 chickHenhack which means you can’t install 5.03 GEN-C.

- 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)
