PS3 3.70 Downgrade with ProgSkeet or Teensy++ Tutorial
THE FOLLOWING TUTORIAL RE-PRINTED WITH ORIGINAL AUTHOR's PERMISSION from RootedSystem
In this tutorial I will go over the steps needed to downgrade any PS3 at 3.70. Their has been alot of updates over the past few days, this tutorial should clear them up.
Before beginning this tutorial you will need to have installed the ProgSkeet or Teensy++ to your PS3. This requires dissembling your PS3 and some soldering work. If you do not want to void your PS3′s warranty you have two options. 1. Buy a second PS3 for homebrew 2. Wait for an exploit and don’t update to any new firmwares.
Requirements
PS3 Phat or PS3 Slim at 3.70 (Must be at 3.70 if not update to it!)
Dump the NOR from your ps3 with the ProgSkeet or Teensy++ it should be exactly 16,777,216 bytes, if its not re-dump it until it is.
EDIT: WARNING: ACTUAL DUMP SIZE DOES NOT MATTER. YOU NEED TO VERIFY THE DUMPS. Just because you have the same size dumps or they're EXACTLY 16,777,216 bytes does not mean you have a valid dump. You can still have a corrupted dump.
Now open up Flow Rebuilder and select “Byte reverse and extract a NOR Dump” from the drop down and drag your dump to the “Select the input Dump File”. Click execute and it will build a new volume (bin.REV).
Next open up Transplante, in “donador” select your nor-dump.bin.REV and for “receptor” select downgrade.bin and click go.
Now that your downgrade.bin should is successfully hexed open Flow Rebuilder back up. Select “Byte reverse and extract a NOR Dump” and drag downgrade.bin to the bottom option and click execute.
It will give an error but this is normal. You should be left with “downgrade.bin.REV”, this is the file you will flash to your console.
Once flashed turn on your console but don’t press anything! Shutoff the console, we’ll need to put it into factory service mode.
Download lv2diag and cfw put these onto a usb drive and plug them into the far right usb port.
Turn on the console, it should shutoff within 10-15 minutes. Once the flashing is complete and the console is off; remove the usb and turn it back on. You should now see the xmb. Shutoff your ps3 once again. Download lv2diag FILE2 and put it overwrite the old one your usb.
Put the usb drive back into your ps3 and turn it on again. This time it will turn on for 20sec and then shutoff. Your ps3 is now successfully on CFW 3.55 Kmeaw.

Is there anywhere that has a good diagram/tut for installing progskeet?
Also does anyone know anything about this solderless solution or where to get the progskeet clip, I would greatly appreciate it.
For good diagrams, check their website. The solderless solution is for NAND only. So you'd need 2x360-clips. It isn't marketed by the progskeet team though.

Please edit that.

His warning could be added to that one.
Maybe add a couple things to make them more obvious on a first read through:
Requirements: Automated Hex = Transplante, used in step 2
Step 5 How to turn off the console without pressing anything? Logical guess is it doesn't matter, but it is not fun to guess for someone doing it the first time.
Also, what method would you suggest to verify the dumps? Some people dump the flash twice and compare the results (with hexeditor or commandline command: fc (windows), they should match). Is that okay?
Does it matter what firmware version the console came with or does the minimum version in the syscon need to be checked first? On other threads, there seems to be some confusion about using a different CFW besides Kmeaw. Is it possible? When does a firmware like Rogero's have to be used?

Yes, it matters A LOT what the minimum version is. But it doesn't necessarily matter what firmware the PS3 came with.
The Rogero CFW v2 is the same as kmeaw, just with LV2 hash checks patched. While downgrading, you need LV1 patched, or you'll end up with RSOD, or YLOD, one of those. I'm pretty sure it's RSOD.
