August 15, 2011 // 5:09 pm - Today Italian site DiGiTaLAnGeL (linked above) reports that they have successfully downgraded a PS3 Slim 3.70 Firmware unit to 3.55 Kmeaw Custom Firmware, followed by a New Method - PS3 Downgrade v2 Supports all NOR Flash from TwoStone.

Similar to the PS3 Firmware 3.6x Downgrade via Infectus, this round they have downgraded a PlayStation 3 v3.70 Firmware console using ProgSkeet with the assistance of Dospiedra with a roughly translated PS3 3.7x Downgrade for Slims and Fats with NOR Flash now available.

To quote, roughly translated: The first downgrade to 3.70 on PS3 Slim 3:55, DiGiTaLAnGeL tested by us!

For the first time, we have been involved in something truly spectacular We were the first in the world to test the downgrade from 3.70 to 3:55 on a PS3 Slim (With flash memory, "NOR") using the ProgSkeet and patched some files provided by dospiedra, a famous Spanish coder already riding high for having discovered the method of going back to 3.55/3.41 with the PS3 (FAT flash memory "NAND").

After several attempts, in collaboration with dospiedra, we got to go back from 3.70 to 3:55, enter the factory mode with a simple key to jailbreak, rifleshare a modified version of 3:55 to prevent the SYSCON (the registry in between downgrades) was consulted during the downgrade and now we are happily at 3:55 KMEAW!

With this version of moddata 3:55, you can perform a memory dump today and you can switch on the fly from 3:55 to 3.70 without having to do this all the time-consuming process: using progskeet fact you can go straight to 3.70 changed to 3:55!

Dospiedra said it will release details on the patches applied to the NOR and the update file as soon as possible.

New life for those who arrived too late to enjoy the benefits of the 3:55?

Oh yeah - soldering all of those wires can be quite "fun", it should only be for the experienced user, if you think you want to give it a go - buy a broken board off ebay, and try soldering the 32 or so wires to it, if you did a good job, then give it an actual try. Then again, if your PS3 is bricked, you really have nothing to lose!

no way i'm gonna try it. i have ps3 on OFW for online and one on 3.55 Kmeaw just curious if this could lead to a downgrader or even a way to customize 3.6x+ firmwares.

I wouldn't want to risk it myself... The Infectus is quite a task for average users to solder (CJPC was able to do it, but I wouldn't attempt one) and most probably don't own the hardware so you'd have to buy it and then hope you don't mess up the PS3 installing it hehe.

While this is good news for the skilled techs out there, for the rest I'd say getting a used PS3 with lower Firmware is easier.
