Gaming How to downgrade your psp 3000 using 6.20 TN-B HEN

[Bryon15]

Okay this is for everyone with psp 3000's that are on OFW 6.20. Do not try this on a psp go! These links will teach you how to downgrade your psp 3000 to OFW 5.03 so you can install chickhen R2. Your probably wondering why you should do this since you already have 6.20 TN-B HEN. The reason is simple. It's because chickHEN R2 is fully complete while 6.20 TN-B HEN isn't. Meaning it can do much more stuff. Like playing just about every psp iso/cso up to ofw 6.31 as well as ps1 games. Here are the links.

first you'll need to be running 6.20 TN-B HEN, get that here

doesn't work with 3000 4g models.
datecode 9D and up (and maybe some 9C)

these models only can downgrade to ofw 6.00

after you have chickhen R2 up and running, you need to install CFW.

Finally once you've done that you need to upgrade to the latest version.

Oh I didn't know that. Thanks for the heads up. I did this on my psp 3000 and it worked perfectly. I guess I don't have the 4g model. I'm lucky

EDIT - how to tell if you have a 3g psp or 4g psp
