To quote, roughly translated: Hello, I've been working on this project about two months now since I've gotten to work as public so that everyone can use, this tutorial is for consoles with 256MB NAND flash does not mean it does not work in 16MB in itself is changed almost the same in those with normal flash, but because even I have my fat 16mb 80GB I have not been able to neither prove nor verified.
Nougat (the phrase I owe to some forero around here that I really liked the expression):
122w ago - Just under a week ago we reported on news of a successful PS3 downgrade from 3.55 to 3.41 Firmware, however, it ended up not being reproducible until a PS3 3.55 to 3.41 Firmware Downgrader arrived today courtesy of solidpsycho through a guide from AmazingLarry.
To quote: Here is a patched 3.41 that allows you to downgrade. I patched the info0 to 356, and I also used Warrens method to bypass the br drive during the update. I have tested this on both of my PS3's and haven't run into any problems.
3.55 Downgrade has been confirmed on both FAT and SLIM consoles.
Please note you CANNOT use these files if you bought a PS3 that came stock with FW 3.50. DO NOT DO IT. STOP NOW.
123w ago - Update: KaKaRoToKS has now confirmed that the PS3 3.55 downgrade is no longer possible, tweeting the following: "sad news.. downgrade worked, but not reliable, only works with one of Xtse's ps3s, but can't reproduce it.. I'm going to look for another way. nope, it only works on one machine, even if same model, it doesn't work on it. No idea what's different about it..."
Today KaKaRoToKS has confirmed via Twitter news of PS3 downgrade success from version 3.55 to 3.41 PlayStation 3 Firmware.
This confirmation comes just days since his PS3 Custom Firmware surfaced and under a month after the PSGrade free PS3 Downgrading hex codes arrived for version 3.5 and below consoles, followed by Sony revoking lv2diag.self file_1 and patching PS3 downgrading in the PS3 Firmware 3.55 update.
Here is his Tweet, to quote: "First downgrade from 3.55 to 3.41 successful, Thanks to Xtse! Method not yet ready for the masses...
128w ago - A few weeks back we saw a video of PS Downgrade in action, and today ANTONIOPS at Spanish site Elotrolado.net (linked above) has posted up some videos showing PS3 Debug Firmware v2.15 being installed via PSDowngrade on a 40GB Retail version 3.41 console followed by running a PS Store demo.
Normally PlayStation 3 service boxes require a proper downgrade PUP file, however, comparing the SHA1 hash of the released PUP confirms it contains nothing special (just the old 3.41) so there appears to be something 'interesting' taking place when downgrading via PS Downgrade.
To quote, roughly translated: The noise you hear when you turn on the PS3 is the reader who is half repaired.
The Debug firmware I've installed the firmware downgrade PSDowngrade 3.41 to 2.15 Debug.
At the moment can only run signed code, such as a PS Store demo.
