PSP developer some1 has updated his 6.38 Downgrader to support 6.39 OFW. If you’re not familiar with this PSP jargon, it simply means that using the 6.3x to 6.20 OFW PSP Downgrader to downgrade a PSP from the latest official firmware (6.39 OFW) to 6.20 OFW.
Simply visit my updated 6.3x to 6.20 OFW PSP Downgrade guide for more information.

some1 for the 6.3x to 6.20 OFW PSP Downgrader
Davee for the initial downgrader release
or people can opt to use neuron’s 6.39 cfw. I would prefer downgrading. But, if you would think otherwise just visit this link guys http://www.psp-hacks.com/2011/05/27/cfw-6-39-me-2-installer-for-ofw-6-39/#more-19362
I’m thinking of posting it as well but you got to remember that neuron’s cfw is only for hackable PSPs.
Hey, Sylv! Neuron has recently updated his cfw. Now PSP 3000s can use it as well.
Found his release for the LCFW 🙂 I’ll get on a new post but it’s still a test/alpha release
I have a psp 3000 (it says 3001 under battery) with 6.37 OFW. can it be hacked? if yes, how?
Yep, you can now install LCFW on your PSP with 6.37 OFW:
Upgrade to 6.38 OFW
Then Downgrade to 6.20 OFW
From there you have a choice of installing 6.20 TN-E or 6.35 Pro-B5
will those CFW allow me to play iso i download from the internet and allow me to use whatever program that people use to cheat on games offline and online? im guessing it’s a hex editor or something
Yes on both counts
its better to take 6.35 pro b5
Can anyone tell me how to downgrade 6.39 TN-A to 6.20 TN-A ?
It there a way to remove TN-A entirely ?
I can’t see ISO and no aloader works.
Just to clear things up, 6.39 TN-A (or 6.20 for that matter) does not include the aLoader, TN Xtended that hasthe aLoader included. To unload TN, just turn off your PSP.
sir i have a psp 6.39 3001 . how can i downgrade it to 6.20 TN-C … if i ever dont want to downgrade it can i play iso cso games if i update it to 6.39 pro-b9 what other application i will need to do this tnx and more power
Your PSP-3000 can only be downgraded if it’s one of the older units, if it’s a new one (one that shipped with 6.3x firmware), you can’t. Yes you can install 6.39 PRO-B9 to play ISOs.
