Xtrusion, a spanish coder from our forums has released an Easy downgrader for those users on PSP firmware 2.5/2.6 that have not downgraded yet. It's easy to use, safe, and best of all doesn't modify and of the original downgrader files. This Easy downgrader users the original dowmdater from Dark_Alex, Mathieulh and Yoshihiro from SonyXTeam and comes in the form of an executable with a great GUI. Every step of the downgrade process is shown in images from finding out whether your PSP has a TA-082 motherboard to using the eLoader.

A voice will explain to you how to do things along with text, and the automatic installer will install all the files required to downgrade for even the biggest PSP homebrew newbies. The only files that are missing from this version are the downdater files which you must obtain from a firmware 1.5 user. Here's what they need to do:

1. Copy the folders downhelper and downhelper% from the folder 1.50 HELPER folder to /PSP/GAME/ in your memstick.
2. Obtain the 1.50 update EBOOT and put it in /PSP/GAME/UPDATE in your memstick. You may find the 1.50 update in our download site here.
3. Init the downhelper program.
4. It will dump your flash and some files from the updater eboot to the memstick. (These files are illegal under US copyright laws, so please do not distribute them in the comments or on our forums)
5. After that, the program will exit. You can now delete the updater from /PSP/GAME/UPDATE
6. You'll notice that you have a new folder in the root of your memstick called "DOWNDATER".
7. That's the folder you'll have to send to a 2.50/2.60 to let them test the downgrade.

Then all you have to do is run the easy downgrader! Remember, there is still a risk of bricking your PSP by using this application. Please read our previous article in order to fully asses the risks of downgrading your 2.5.2.6 PSP.
