Downgrader for PSP v3.50 firmware

[pspcrazy]

We they it would be done - although some people even said they couldn?t - and so... let there be a downgrader! Noobz are proud to present a downgrader for any PSP
This downgrader is for v3.50 firmware, and includes a port of the Homebrew ENabler (HEN) for firmware 3.50. It will automatically detect all known PSP motherboard types, and do the appropriate steps to ensure a safe downgrade.
Before we get started, let?s have the obligatory warnings:
Any downgrader carries some risk of permanently damaging your PSP. We?ve done everything we can to remove as much danger as possible, but if you choose to use this downgrader, you are accepting all of the risk involved. Nobody else will be held responsible for any damage to your PSP, howsoever caused.
Recent Sony official firmwares (3.30 onwards) have included checks that block upgrade from previously-downgraded PSPs with TA-082 or later motherboards. If you use this downgrader on such a PSP, you will lock yourself out of official firmware updates - although you will still be able to use new OE firmwares when they are released. We intend to release a tool to allow a return to official firmwares in the future.
This software is provided free of charge, so that you can use legitimate homebrew on your PSP. You are explicitly prohibited from selling it, or using it to pirate commercial games or applications. If you want to play a commercial game, do the decent thing and support the developers by buying it. If you don?t, then YOU are contributing to the death of the PSP software industry.
To use this downgrader, you will need the following:

1. A PSP, upgraded to the official Sony v3.50 firmware. You should also set your language settings to "English".
2. A legal Lumines UMD, either the EU (ULES00043) or US (ULUS10002) version. The original, Platinum, or Greatest Hits versions are all fine. Support for the Japanese version will come soon.
3. Sufficient intelligence and english language skills to be able to carefully and throroughly read the instructions.
4. It would also help if you?ve previously run the Illuminati Hello World, so that you?re familiar with how to run the Illuminati exploit.

For instructions on how to run the downgrader, see the Downgrader_HOWTO.txt file in the ZIP.

Contact Sony ASAP, since there is no FW higher then 3.50 out right now
3.50 is the latest Firmware released, so its big news it can be downgraded.

OnTopic: Great to hear, this makes the change bigger i'm getting a psp again. Good job Noobz!

take a picture of it and post it. cuz it shouldn't be over that...

HA! Oooops Sony just put out FW 3.51 with absolutely nothing to gain from upgrading yet again!!! Jokes they didn't but I mean when are they going to stop. Most companies have hackers testing things to see if it can be hacked. Don't they check these things out? Guess who is going to buy a $169 PSP this weekend.

Yeah I own one but I could use a new shiny one with no scratches this time.

DID IT! And it's officially my SECOND PSP to be downgraded.
Here's the path that I had to take: FW 3.11 --> 3.50 --> Did the Lumines exploit --> 3.50 HEN --> 1.50 --> 3.03OE-C

Thanks PSPcrazy for the AWESOME NEWS!!! YOU SO ROCK!!! Well N00bz and Dark_Alex are the ones that REALLY ROCK for finding the exploit, but you know what I mean!

*EDIT* Well, the DOWNGRADE worked,.. but when I tried to upgrade to CFW 3.03OE-C from 1.50 it somehow BRICKED!!! Went throught the sequences and the upgrade started to look good.. it hit ONLY 5%, the upgrade stopped and then the screen went BLACK! I can't believe it.. I now have a PAPER WEIGHT! This sucks! Is there ANYTHING that I can do?
