FIRST NOTE: This is NOT CFW, all it does is enable homebrew and ISOs on ANY PSP with ofw 6.3X. If you have 6.20 then you can hack now, you just have to look at my other posts about 6.20 HEN TN-B and you're good. This is specifically for people who have 6.35 and 6.31 who want to play ISOs and Homebrew.
First things first, select your firmware below, and download the attached file. It is everything you need, set up so you just drag everything to your PSP and merge all the folders, and you are good to go.[You must be registered and logged in to see this link.][You must be registered and logged in to see this link.]
Once you download the file that corresponds to your firmware version, follow the below steps to enabled Homebrew and ISOs (also included is Prometheus ISO Loader that is required to play the ISO and CSO games)
1.) Open the .ZIP file that you downloaded and connect your PSP to your PC
2.) Click and select ALL of the files inside the .ZIP file (hbl folder, PSP folder, ISO folder, and h.bin file) and either copy them, and paste into the root of your memory stick, or click and drag them all to your memory stick.
3.) It will ask if you want to MERGE the folders, click YES to all of them
4.) Disconnect your PSP from your Computer.
5.) Go to the GAME section of your XMB and select the Japanese game that should be displayed on your memory stick
6.) Once the game loads, you will see a little blinking white hand pointing at an option, that option is LOAD SAVED DATA. that is how this HEN hack works, so you want to select that option, but since it is a Japanese game, you select with O and move BACK with X, SO PRESS CIRCLE.
7.) Some Japanese words will pop up, and then your screen will go Black with some Red words up top, and some white words below it.
8.) It will then switch to another screen and it will say WARNING: MEMORY LEAK! dont worry, that is perfectly normal.
9.) Now if done correctly, it will reboot your PSP. Go to Settings>System Settings>System Information and your software version should now say either 6.31 PRO or 6.35 PRO depending on where you started.
10.) Now, reconnect your PSP to your PC and place any ISO/CSO games you want to play inside the ISO folder on the root of your memory stick and all your Homebrew stuff inside the PSP>GAME folder
11.) To run your ISOs go to your GAME section of your XMB and run Prometheus ISO Loader and you will seee a list of your ISO files, pick one.
Enjoy your ISOs and Homebrew, and tell everyone that SneakyCodes is the best place for new hacks.
Anyone with any problems, or questions, reply and ill help you out, i successfully did this to both of my 3000s so it definately works 100% of the time.
ANOTHER NOTE: This is just like a HEN exploit, so if you lose power, or freeze, or reset your PSP, you have to re-do it. Just run the Japanese game every time you lose power, and you are all set.
