(adsbygoogle = window.adsbygoogle || []).push({}); I was told today that if your firmware upgrade gets corrupted during installation, that you receive the option to install firmware from an external device. Now, if this is true, could you possibly, while upgrading to 3.50, purposely corrupt the installation by shutting down power, and then re-booting without internet connection, install Firmware 3.41?

I have no idea if this would work, just another theory. And YES, I do know it's stored on the NAND FLASH, but if you corrupt the current one, could it possibly be downgraded to prevent further damage to the sytem?

Theory #2.
You could use proxy server while updating, redirect the 3.42 Update file to the 3.41 Update file mid-update, and then when the file is corrupted during the installation, return to your flash drive, and install 3.41 firmware.

there was a rumour a while ago that you used to be a way to do this with god of war 3, if you google hard you can find some of the posts on other forums

Good luck on your work. I never even once thought about updating the moment I heard about the jailbreak.



I suppose soft googles just won't do it, huh?

lol sorry, I just never heard anyone say google hard.

i think there is a way to do it with a slim 250gb

I have a 250gb ps3 on 3.42 fw if you want to use it to test let me know I'm game

ive got one too :p

they said this

"Start a game with your usual hdd then swap it to a new hdd or one under 3.41 and go to update from usb drive or whatever and it will recognize and dowgrade"

i know it sounds stupid but if someone has an extra hdd lying around then go for it..i wanna know if it works

I'll try it! Odly enough I have a 80gb HDD (main 3.42) and a 20gb HDD (secondary 3.41) ! I'll try it lol

This does work...
The proxy i tried automatically downgraded to v1.00,
So then I have to upgrade with a USB flash drive.

I will try to do it now im downloading 3.50 so i have to test it, we love free challenge lobbies!

let us know if it works havent updated today to 3.50 gotta go out of the city today dont have time to try:cry:
