2.71 Generic Downgrader (TA-082 motherboards should not downgrade below 2.5!) Does not require GTA.

So how does it work? Well, all you need is Dark_AleX's 2.71 Homebrew Enabler Rev.C, and the EBOOT.PBP file of the firmware you want to downgrade to. So you can downgrade from a 2.71 to just about every other firmware including 1.50,2.0,2.01,2.50 and 2.60.
Get all the available updates here (Newb here!)

Instructions:

Download Homebrew Enabler for FW 2.71 using the Link below.
Follow the instructions in the readme file of Homebrew Enabler for 2.71 Rev.C to install HEN-C
Once done, reboot your PSP and run the Homebrew Enabler using the Photo Menu.
Now simply extract the files in the downgrader archive below to your PSP and paste the EBOOT.PBP file of the updater into the PSP/GAME/UPDATE folder.
Now just run the updater using the Game menu!

Here's what Dark_AleX had to say:

"This downgrader lets a psp running firmware 2.71 and HEN C to downgrade to any version from 1.50-2.60, or even reflash the 2.71 version. This downgrader is safer, faster, and a lot easier to use than the previous downgraders. It also makes a clean firmware install, since this time there is a format of flash0 (just like sce updaters do). A firmware dump is not needed, only the eboot.pbp of an update.

Ta-082 users can downgrade to 2.70/2.60/2.50. TA-082 users, DO NOT downgrade below 2.50. Youll Need To Use To Downgrader In The Next Section To Downgrade To 1.50

So all of you who've been waiting for a simple solution, I don't believe there can be one simpler than this. If you're still on 2.5/6, you can safely update to 2.71 and either wait it out for more homebrew, or downgrade to 1.5...But looking at all these developments, I feel that 2.71 might just just replace 1.50 as the golden firmware soon. Anyways, enough of talk, here's the download link below. Enjoy!

2.71 Downgrader For TA-082 Motherboards (For Downgrading TA-082's To 1.50 Firmware)

This program is specifically designed for 2.71 HEN-D users with a TA-082 motherboard. HEN-D, which enables 2.71 users to execute homebrew via the XMB, will be required for this downgrade process, and if you do not have it you can download it at the link provided below. Dark_Alex has also provided a detailed installation of this process detailed in the readme (please read the readme after you download).

1. Copy the UPDATE and idstoragechange folders into /PSP/GAME/
2. Get the official sony 1.50 eboot and put it in the /PSP/GAME/UPDATE folder with the name of UPDATE.PBP
3. Run HEN-D if you are not already running it.
4. Execute the idstoragechange. It needs 75% battery. It will change some keyes of your idstorage needed to downgrade the ta-082.
5. The program will exit to the XMB. Now execute the generic downgrade, which will show in the xmb as "Update X.YX" in the psp language.
6. The generic downgrader will also need 75% battery. IT will downgrade your psp to 1.50.
7. At the end, it will ask you to press X to restart the psp. Do it.
8. If all went fine, you'll receive a blue screen telling you to press O. Do it, and reenter your settings. Welcome to 1.50.
9. If things didn't go that fine, you'll have a non-functional psp, aka brick.

Warning: As always, there is a chance that you may brick your PSP running a downgrader, so please try this at your own risk and follow directions exactly.

2.80 Easy Downgrader (DOES NOT WORK ON TA082 PSPS!)

As mentioned above, this app is in its very early and unstable stage. The results are as unpredictable as Sony's marketing schemes, so again, it's best that you read, reread, and reread the readme file some more that comes along with the download. Right now, the main concerns are: THE PSP MUST NOT HAVE A TA-082 BOARD and the owner must use the recently released xloader instead of the earlier eLoader. Cause if not, you would end up having one useless piece of gaming device. The full instructions are:

Download Link: PSP Downloads | Easy 2.80 Downgrader

1) Format memstick with a 2.8 NON TA-082 PSP.
2) Connect PSP via USB and run easy installer.
3) Select PSP drive in the easy installer and let it install the files.
4) Turn off your PSP.
5) Turn on your PSP and goto PHOTO -> Memory stick -> xLoader 280
6) You should see two icons in the xLoader 280 folder. If xLoader loads correctly then nothing should happen. If it fails then MS will blink and then PSP will crash.
7) Once xLoader is run successfully, goto GAME -> MEMORY STICK and run the downgrader.
8) You should see the DG menu.
9) Pray to God and cross your fingers.
10) Hit O to start DG.
11) Wait for it to say "Finished. PowerOff to exit"
12) Hold Power switch up until psp is completely off.
13) Pray again.
14) Turn on PSP, you should now get a Blue Screen Of Death so press O to reset settings.

THIS IS A EARLY VERSION. USE WITH CAUTION
