My friend was mad at me because I made him download 2.6 so he can play Syphon filter :lol:


A previously unknown developer, son (aka Lirpa Sloof) from team ataraxia, has managed to squeeze out a downgrader for firmware 2.60 -- to firmware version 1.50. Before now, it was commonly understood this was "impossible" among the general PSP community, but son has managed to find a way using various hacking techniques he acquired through playing quake 3.

Like all downgraders, you must realize that this DOES WRITE TO FLASH MEMORY, AND THERE IS A RISK OF BRICKING YOUR PSP! There are a few steps required before you downgrade. Firstly, you must erase all videos on your PSP, as this takes advantage of an unknown .mp4 exploit on the PSP. The steps are relatively easy to follow, and quite similar to the MPH Downgrader, which downgrades from versions 2.00 to 1.50. The steps include:

Steps to use the iDowngrader:
- Create an UPDATE folder in the /MP_ROOT/100MNV01 folder of your memory stick
- Copy EBOOT.PBP (update 1.50) in /PSP/GAME/UPDATE folder
- Unpack iDowngrade.zip
- Copy iDG.mp4 into your /MP_ROOT/100MNV01 folder of the memory stick
- Copy h.bin to root of your memory stick (meaning in ms0:/)
- Copy index.dat in root of your memory stick (meaning in ms0:/ as well)
- Plug in the AC adaptor

Once all of the files are copied onto your memory stick, this is the tricky part, you must now watch the video. The video will start to play, then freeze the PSP, which is normal. Now you must turn off your PSP, then turn it on, which will bring you to the 1.50 Firmware Update. Like the MPH Downgrader, this one errors at 99% but is normal. Restart your PSP and turn it back on. You will have PSP firmware version 1.50, and it will lead you through setting up language and time etc.

I still don't know why people want to play old games on a 1.5 PSP and not be able to play the awesome games that are finally coming out.

Has anyone tried this yet? They want to downgrade so they can use homebrew, which is what a lot of people bought the PSP for in the first place.

I used to be in to that but no longer. I don't see a point to homebrew games and playing old games on my psp.

I have the latest revision and I can play homebrew stuff without going back to 1.5, it's called using the Fanjita Loader, it's based off eLoader, however I must admit that you do need GTA Liberty Cities in order to get it working.

Why downgrade when HB works on 2.60?

There is no point! :|

Actually, it is real! Sold on EBAY for 5 dollars a pop. However, it doesnt do anything and thankfully it does not crash your PSP

Mike - and Eric, when you come on - this is my last day in the office!!! As such, I won't have that much time to write, then at 3 me and the lady are going away for the weekend. We may come home Sa****ay, but we'll likely be back Sunday. Starting Monday, I'll be on Monday-Wednesday, then Sa****ay morning.

Mike, thanks for the help this week during Sony's press conference - that was a lot of fun!
Eric, hope you had a blast at E3. Lets catch up Sunday night or Monday.
