Downgrading Is Easier Than We Think. .

[THE ANSWER]

Well I already have a 1.5, but its the idea of downgrading a 2.6 with a version changer like pspsetx sound, very realistic, but I would like to know if pspstex works with the GTA eloader, since I dont own the game I cant try to see if pspsetx works, If somebody tells me that it does work Ill buy the game and Ill go all the way trying to downgrade it.

The PSPSet App will never work (chances are it WILL brick your PSP). The MPH downgrader uses a special file called index.dat which contains the firmware version info. Sony has changed how they store the formware version info in later versions so it's not that 'simple'.

You can't write to flash in anything 2.01 and up so there is no chance...

[Libernullmal]

what about having a program that uses the usb connection from your pc to access the flash and editing or coding or whatever it is? I am sure I am I have no clue but I kinda think about how they get into a Cisco Router through RTJ22 and a laptop.... eh just a though.

I'm shure .. sony made the 1st downgrader. This maybe was already posted here.. Sony hacks the psp itself.. and someone @ sony know a magic combo to downgrade on the fly.. triangle..triangle..left..square.square.. down (3 times).. something like that.. I'm shure!

unfortunately you've just pulled off a "fatality" on your PSP and bricked it...

Alright I have a 2.60 PSP (and I regret buying one if it weren't for the snazzy white color and Sharp LCD)

My friend and I are trying to figure out how safe it'd be to run PSPsetX on it to downgrade the 2.60. Now I'm not willing to forfeit $250 to see whether this 50/50 chance works. So I've come to this forum in desperate hopes of an answer.

Here's what we plan to do:
1) Run the GTA exploit to run Homebrew for 2.6 (I already own the GTA UMD)
2) Run PSPsetX 0.2 (or would 0.3 be better?) to change the version name to 1.0
3) Run the PSP updater to 1.5

We also plan to do more testing on the location and integrity of the index.dat

Thanks SO much for your viewing and possible replies - they are GREATLY appreciated!!!!!!

Be patient, no there isn't a downgrade for it only 2.00 but you can still run a small portion of homebrew apps on the 2.60

Which games run on 2.6 and what are the constraints when writing one.
And please tell me that they don't require GTA. Because I am really short of cash and its either buy GTA or buy a new computer. Obviously (If you read my Marathon thread) I would have to choose the computer.

Well thanks, Bye.

Inigo Montoya, dont worry about the computer so much, if you port marathon, you will have enough money to buy a cheap laptop/pc.

Ok everyone, we all know that hardly anywhere ships 2.00 and lower and our recent buyers are stuck with 2.01 and up. Also the urge to upgrade is increasing bit by bit and im sure a lot of us have been playing our emus for some time. (I'll never upgrade though. . ) Anyway we all remember the 2.00 downgrade correct? After that text came up we went over to the system info and saw that it said 1.00 and it was actually a 2.00 but was disguised, like a version changer. If we can get a SNES emulator to run on a 2.50 than we can Def get a downgrade at least for 2.01 All we need to do is create a version changer that makes it look like it is a 1.00 like we did before. All we need to create is a version changer and than run the 1.50 update like we did before. Will it brick our psp's? Maybe! But does anyone else have any other brighter ideas? Also-I agree wirth the fact that we should focus on cracking the newer systems but it's just not happening fast enough. Honestly, I believe that not enough time was spent on the 2.00 firmware. It was like ok 2.01 is out screw working on this firmware man. We only have half of the homebrew running, screw it! We progressed better working on 2.00 than we will on 2.01 and up because the task is harder.

WOW,
are you retarted?
this was covered a long time ago, 2.01 and above is totally different than 2.0 and below. The whole make up of the way the fimrware is written is way different. People tried to make a downgrader using a version changer and what happend every time......

The PSP got bricked.

next time do a little research before you go blast coders for not making a downgrader. They didnt even have to make a 2.0 downgrader and a 2.1 and greater loader. So be gratefull. If you want a downgrader that bad take up coding or sneak into sony and steal their encryption key so you dont need a downgrader.
