1.5-1.0 Downgrader

[Video_freak]

i just got my psp last week and i was thankful that i will not pay that much for a downgrade when i saw you post but saddly i have a version 2.5 with ta-082 or ic1003 and the downloader said that i cannot downgrade this... can you help me plsssssssssssss

You can tell if you have a TA-082 mother board by opening the UMD drive and looking in the top fight corner. If you see writing there, then it's a TA-082. If the writing is in the top left hand corner, then it's ok to downgrade. If you do have a TA-082 motherboard, we cannot help you, for trying to downgrade it will probably result in a brick.

I think I heard something about a modchip that supports the TA-082 motherboard so he could downgrade with that but im not sure if its out yet

Hey there. New to the boards. I actually found this board looking for a way to get my Japanese PSP back to 1.0. I always regretted updating my firmware.

Before I give this downgrader a try I had a question. Will I still have the inverted X - O buttons that japanese playstations have? I've pretty much have grown to love this configuration and do not wanna go back to the US configuration.


Edit: Sorry about the original post, I won't make the same mistake twice.

Thnx for the help below. VVVVVV

I know this is knid of bringing back an old thread, but the system didn't allow me to create a new one.

I have been away from the PSP scene from some time now(I was in on the start and in fact produced some of the first homebrew games, but got bored).

My question: does anyone know if there is going to be a devhook for 1.0 firmware? I've got an original japanes virgin 1.0 psp, and don't want to update. Since more people can get this one now it should be best to use it as a base.

I dont think there ever will be a Devhook for 1.0 because hardly anyone is on 1.0

Theres really no benefits off having 1.0 except for faster loading homebrew.

Ok, thanks for a quick reply.

I think I'll just have to upgrade my psp to 1.5, or I won't be able to play any games. I've been looking for the 1.5 upgrade, and found some. Is there any issues with using a european upgrader on the japanese machine? I can't find any japanese upgrades...

Does anyone know the reason why devhook only works on 1.5->? Are there any new libraries that provide special functionality or something?

Youll be fine with a euro upgrade.

Not sure why it only works on 1.5

DevHook 0.22 is the one I use. (need it for Lumines (fw1.5)).
It plays quite a few FW 1.5x games. (sadly, it only works with umd backups in .iso format though)

Apparently DevHook 0.30a also works on FW 1.00 but I can't get it working on mine.
Both versions can be found at www.psp-hacks.com
under "downloads->loaders"

Hopefully, booster will try getting newer DevHooks to run on FW 1.00 someday, but for now this is all we have.
