I bought a new (2008) PSP and now have version 5.01 for firmware, is there a way to run ISO's from the mem stick. Please include links to software if there is a way to do this.
To downgrade (and get a custom firmware) or unbrick your PSP, you need the Pandora's Battery. There is three ways to get the Pandora Battery. You will also need to make the Magic Memory Card.
1. Find a someone who has a Custom Firmware that is willing to let you borrow their psp. You will use their psp to softmod the battery. Meaning using software to make the Pandora. If you willing to do this, follow this guide:
2. Hardmod the battery. Meaning that you have to open that battery up, and pulling out a pin. Note that if you pull the wrong one, your battery would be messed. If you are willing to do this, follow this guide
3. The most safest way, is to buy a premade pandora battery from the internet (use google or ebay).If so, follow this guide or use the same guide on the second step. I recommend buying from DealExtreme for $10.
NOTE : TA-088 motherboards - Sony has just made new motherboards that stops the usuage of Pandora. If, you psp comes with 3.71 and up when you bought it. Please follow this GUIDE
