94w ago - Following up on the
initial news, today the
E3 Team have made available a video of their E3 Flasher downgrading a PS3 Slim 3.70 Firmware console to version 3.55 without any soldering required.
To quote: E3DIY team announces a successful Slim Downgrade v3.70 to v3.55 with our new E3 FLASHER!
In only FIVE minutes, the whole downgrade progress was completed!
Time is short and operation is very easy, this is because of our exclusive special E3 FLASHER design:
- ONE-Button Operation and NOR Flash onboard!
- E3 FLASHER compatible all NAND FLASH and NOR FLASH consoles
- With SLIM Consoles, no need for any soldering!
- But with PHAT Consoles, some soldering will be needed!
In this video there no images of the E3 FLASHER as we need to keep our design under wraps until it is ready for release, I hope everyone understands.
The official version should be released next week, at that time there will be more videos and pictures and everything will be available to the public.
Also below is an E3 Flasher PS3 Dual Boot 3.70 to 3.55 Firmware video and details via e-mail:
E3 FLASHER - Dual Boot (3.70 to 3.55)
- E3DIY team success dual boot with E3 FLASHER, you can switch 3.7 and 3.55 in few only a few seconds!
- Easy with 1 key operation.
- E3 company will release all details like picture, installation, operation and price next week.
- Team E3DIY get another great progress for PS3 with E3 FLASHER, it will release at the same time next week.
PS: 4times switch showes same MAC address, to prove it is the same console.
Finally, from
damox, to quote on PS3 3.70 to 3.55 Firmware downgrading via
Dospiedra's
downgrade v2 patches:
This post will look at the different DATE-CODES that are present on the casing of a PS3 and if that DATE-CODE relates to a console version that can currently be downgraded from 3.70 to 3.55 using dospiedra’s V2 downgrade or a FAT console alternative.
DATE-CODES
The principle behind DATE-CODES is simple: the first character represent the YEAR, and the second character represents the QUARTER of that year it that console was manufactured.
DATE-CODE of “XY” would mean the console was manufactured in the “Y” QUARTER of YEAR “X”. Simple right?
6A - Downgradable (Never Produced?)
6B - Downgradable (Never Produced?)
6C - Downgradable (Never Produced?)
6D - Downgradable
7A - Downgradable
7B - Downgradable
7C - Downgradable
7D - Downgradable
8A - Downgradable
8B - Downgradable
8C - Downgradable
8D - Downgradable
9A - Downgradable
9B - Downgradable
9C - Downgradable (Slim Introduction?)
9D - Downgradable
0A - Downgradable
0B - Downgradable
0C - Downgradable
0D - Downgradable
1A - Downgradable (Factory Firmware 3.55 and lower only!)
1B - NOT Downgradable
1C - NOT Downgradable (Not out yet?)
1D - NOT Downgradable (Not out yet?)
The Date code can be found in the following locations (depending on your console type):
PS3 FAT: Sticker on the back.
PS3 Slim (CECH2 Series): Sticker on the bottom.
PS3 Slim (CECH3 Series): Sticker on the back.
UPDATE 1: I have been told that only consoles that come with firmware 3.55 and lower from factory are the only consoles that the downgrade should be attempted with.
Simply beautiful 
Thanks for the update 
Translation needs a bit more work (I know it's Google Translate's best Boss
• The Fat 256mb NAND PS3's require soldering and doesn't support Dual Boot.
• The Fat 16mb NOR PS3's requires some sort of soldering and does support Dual Boot.
• The Slim (16mb NOR only) PS3's require soldering in some capacity and does support Dual Boot.
But coming soon:
• The Fat 256mb NAND PS3's won't require soldering and will support Dual Boot.
• All the NOR PS3's won't require soldering at all.
I hate reiterating the article, but someone will ask the questions lol
I though there was no soldering involved for the slim, oh well.
