PSP 3000 and PSP 2000 with V3 Motherboard Only on Firmware 5.03
PSP Developer Liquidzigong has released Prometheus-3 for PSP-3000 and PSP-2000 TA088v3 users on firmware 5.03. Like the other releases you need to be running OFW 5.03 and have custom firmware 5.03 GEN-C installed. FW 5.03 is needed so you can run a VSH tiff exploit like ChickHEN R2 or MHUSpeed. This new Custom Firmware 5.03 Prometheus-3 update will run all the latest 6.30 & 6.31 games. You shouldn’t get anymore 80010087 start error codes if you try and run a 6.30 or 6.31 game.
Custom Firmware 5.03 Prometheus-3 changelog:
Improves the compatibility of CF with the latest games that require the official firmware 6.30/6.31
Installation:
Install and run ChickHEN (or MHUSpeed)
Install CF 5.3 GEN-C (if not already installed)
Extract the files in the Prometheus-3 5.03 to PSP / GAME
Start the Prometheus installer
Install 5.03 Prometheus-3 by pressing the Cross button
Disclaimer: I haven’t tested this yet, since I no longer own a PSP-3000 or a PSP-2000 with a TA088v3. We take no responsibility if you somehow manage to brick your PSP.
