Easy downgrader 1.5 --> 1.0


Xtrusion from our forums has released another Easy Downgrader for those who want to downgrade a 1.5 PSP to version 1.0, the PSPs original System firmware. Just like Easy Downgrader for 2.5/2.6, this Easy Downgrader uses Dark_Alex Yoshihiro and Mathieulh's original downdater, this time for 1.5 --> 1.0 and adds a nice GUI, sound instructions and complete installation (apart from the dumped firmware files) needed to downgrade your PSP from firmware 1.5 to 1.0.

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. You will need someone with an original 1.0 PSP in order to get this to work.

Instructions
  1. Find someone with a 1.0 PSP and get them to install the downhelper program from the downdater download.
  2. Copy the downhelper100 folder to /PSP/GAME/ and start the program.
  3. It will dump your flash and your ipl to the memory stick. After finished, the program will exit.
  4. Send the folder created at the root of your memory stick called "DOWNDATER" to someone with 1.50 to allow them to downgrade using the Easy downgrader app.
Remember that PSP firmware version 1.00 still hasn't got any special applications or uses, so there isn't any reason to leave 1.50 (unless you're a developer) at the moment. You will receive this warning when you run the Easy Downgrader.

Super.. mais je reste en 1.5 ;-)

 » Taking it too far

Nothing wrong with 1.50, and I think some homebrews have issues on 1.0

   by monaco (Unregistered) - 2006-07-08
 » yea no reason

no reason to leave 1.0 because no devhook (could be wrong) and no iso loader

 » a bit pointless

most homebrew is built for 1.5 so what is the point if it is less compatible?
the only good thing would be a custom firmware

 » whats the point

I dont get the point of haveing it at 1.0 is there better games or something im just a confused little man.......

   by flammingcowz - 2006-07-08
 » ...

yeah 1.50 is better right now but give it at least a month, theyll port things like devhook and stuff like that over to 1.00 and since that boots eboots faster, can run anything without hacks or exploits, and itll boot anything its told to boot, itll b the best firmware

 » the point of this

the point of it is so developers can have the oppurtunity to work on 1.00 firmware which has NO SECURITY to bypass. This means they can freely explore 1.00's workings, nooks, and krannies to their hearts content. This also opens up the possibilty of custom firmware for the psp without the need of the undiluated platimum hardware mod. Us regular joes that appreciate homebrew but either have no programming skills and/or time, should stick with 1.5 for the sake that is the most supported firmware for homebrew at this time.

   by emmortal - 2006-07-08
 » yea i agree with #7

even though 1.5 is the best firmware right now because 1.0 can run eboots without any hacks really it can quickly become the best firmware especially with dev hook on it

 » 1.00 Downdater Files

Does anyone know where I can find the DownDater files to downgrade my 1.50 to a 1.00?

I have 2 PSPs with 1.50 FW and want to downgrade one to a 1.00, since 1.00 has some advantages (not many)

2.01-2.6-1.5-2.0-1.5-1.0 and now back to pure 1.5:)

 » A CUSTOM FIRMWARE IDEA

hey some of you will know about the EPSILON BIOS which lets you play full homebrew and ISO loaders on firmware 2.71

now that we have ver 1.00 could it be posible to use this bios on our psps by just flashing it?

if you don't know what i'm talking about read here http://pspupdates.qj.net/Epsilon-BIOS-Undiluted-Platinum-Homebrew-on-2-71/pg/49/aid/56841

 » Custom Firmware :)

A custom firmware on a 1.00 psp sounds very nice indeed. Its the only firmware which can truly run unsigned code, not of great use at the moment because it hasnt been taken apart properly yet, but that'll change :)

 » Question

this maybe a stupid question, but can 1.5 homebrews work on 1.0?

 » what advantages?

>>I have 2 PSPs with 1.50 FW and want to downgrade one to a 1.00, since 1.00 has some advantages

And what _exactly_ are these "advantages" ?

There's nothing you can do on 1.00 that you can't do on 1.50, unless you're a dev and want to play with the exploit to allow running unsigned eboot's...

>>@ 25

Advantages --

Faster
No Corrupted Icons

Disadvantages--

Japanese
Not 100% Compatible


But I want a 1.00 and can't find the downhelper files

 » STUPID

This is really stupid becuase it is really hard to find someone who has a 1.0 psp so how can most people do it if you cant find one psp with 1.0 files on it!

   by A (Unregistered) - 2006-07-08
 » Question

How do you know if your psp is a pure 1.5, one of the original. Thanks

   by FLai - 2006-07-08
 » .

I don't get why you would want to go to 1.0. 1.5 IS better. Loads of homebrew apps and games don't work with 1.0 including Devhook. It sucks so don't do it. You will regret it and you will eventually upgrade again.

 » 1.00 Firmware

I want 1.00 Firmware since I have two 1.50 Firmware PSPs and a 2.60 Firmware... So, Devhook...UMD Emuhater and Cash loader don't mean anything to me on a 1.00 PSP.

So, if anyone can help me find the 1.00 Downhelper files... Please help me...

 » another tagger

i got the 1.0 file just email me on bearsfreak1@yahoo.com or even better if u have a myspace account send me a message at www.myspace.com/bearsfreak1 (please use internet explorer if ur goin in to my myspace account it looks wierd on firefox)

   by -P3Z- - 2006-07-08
 » Hm...

I see this as nice work...Then agian there is no reason to downgrade to 1.0 like alot of you said more Homebrew works on 1.5 and sooner or later they might port somethings over to 1.0...but I see it as a platfrom for Dev's to do more with less hassel and HOPEFULLY their would be a Custom Firmware somewhere down the line..

 » Stop repeating everything

You people who keep posting, asking why would anyone want to downgrade to 1.0 please shut up!!
Its been said over and over again, that the point is so developers can produce a custom firmware. If you cannot invision what the posabilitys to homebrew would be with that in place, then just shut up and wait and see.............

1.0 is a firly bad f/w, its slow...

Also stop the mofo-in' spamming!
