Fast Swap Between 3.70 and 3.55 using ProgSkeet & 2 HDDs

For those with a functional ProgSkeet (or similar) setup: You too can now easily swap between CFW 3.55 and OFW 3.70 following DiGiTaL AnGeL's "fast-swap" tutorial.

DiGiTaL AnGeL's tutorial assumes you have a soldered and working chip that is able to read/write the PS3 NOR flash memory. DiGiTaL AnGeL (and Dashhacks) also assume zero responsibility if you damage or render your PS3 a useless brick.
What you need

• PS3 Slim running OFW 3.70
• 2 Hard Disk Drives (HDD)
• ProgSkeet installed and working on your PS3 Slim
• Downgrade.bin edited with your personal data (SEE HERE)
• 3.55 Downgrade Dongle to perform the downgrade process
• Sony OFW 3.70 UPDATE (DOWNLOAD)
• CFW 3.55 KMEAW “NO CHECK” by dospiedra (DOWNLOAD)
• Lv2Diag by Jaicrab (DOWNLOAD)
• Lv2Diag “FILE 2″ to get out of Service/Factory Mode (DOWNLOAD)

Now there is no point in me copying/pasting the full tutorial, so instead click here and scroll down a bit... The fast-swap tutorial is available in both Italian and English; English being at the bottom.
And in related news DiGiTaL AnGeL also shared a video of the ProgSkeet 3.70 downgrade in action... Peep game:
