193w ago - 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?

This method should also work for CECHH and later FAT models - they have also 16MB NOR-flash. Fatties CECHA..CECHG need another method.

Swapping HD and flashing proper image.bin won't take hours. Cool would be to glue a PCB with 16MB NOR flash and connector to HD so you would swap the proper flash the same time you swap the HD

No, the Infectus downgrade method is for the older NAND consoles. The new consoles are NOR based which require a progskeet or similar to interface with the flash.

No, no, no.... This is simply to downgrade your console to the 'special' firmware versions (for jailbreaking/installing CFW) such as 3.41 or 3.55 (or whichever you choose)

someone needs to figure out how to make something that you can place over the processor and hook in to it with out soldering make something like a bottle cap for it so that all you got to do is place over the processor and lock it over the processor.. it cant be that hard.

think how they got other computers and that might help. what needs to be done is make a mold of the processor and design a cap that locks on the processor and after that more people will buy the mod chip i know this is what everybody is waiting for because they don't want to miss up their ps3 make the cap for the processor.
