To quote: Last night I had the chance to try and downgrade a Slim Ps3 (JSD-001 board with Spansion NOR) version 3.70 to CFW 3.55 using Dospiedra's downgrade v2 patches.
I managed to get a clean dump of the NOR using my ProgSkeet (latest QT port used), created a patched Downgrade.bin image using the 6 patched files from Dospiedra and a hex editor, then I flashed the image to the PS3 NOR, dumped the NOR another time and verified that all was written fine.
Then I continued with the normal downgrade procedure, go into service mode, update using the 3.55_no_check.PUP,...
90w 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...
To quote, roughly translated: Today I'll write a tutorial to "fast-swap" between CFW 3.55 and OFW 3.70, using 2 HDDs... at the end of the tutorial, you'll be able to swap between the firmware just flashing a dump on your PS3 using Progskeet. (instead of downgrading and losing all data).
The first steps are not so easy, so take your time and go on, by the way, you must have some skill with Progskeet, and it must be 100% working...
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.
