E3 FLASHER , downgrade 3.72 to 3.55 successfully! Dual-boot v3.72 and v3.55 successfully! With E3 FLASHER, all is so easy, just switch and works!
And another BIG news is E3 will provide NOR FLASH CLIP free in our 3K limited version! So all Slim models now supported and versions of FAT consoles with NOR and no need to solder anything for downgrading, or dual-boot!
NAND FLASH CLIP also fininshed, will be available in the new up-coming E3 FLASHER NAND version.

I'm certain it will be a solder solution. If it was USB/Solderless it would have been hacked long ago. This is going to work like Infectus or Progskeet or the old XBOX1 modchips, where the chip responds to the CPU's bootup request for BIOS and and inserts the CFW into the system from its own NOR/NAND instead of the one on the motherboard. That way you can install OFW 3.70 for new games and CFW 3.55 for homebrew. It's a step in the right direction, but still locks us out of all games that are 3.56+ that can't be hacked.
Agreed, while things like this are great for developers most end-users won't bother with hardware solutions that involve opening the PS3 and a lot of soldering as it isn't worth risking damaging the console... they will just wait for a more user-friendly solution to come.
I think the reason the original JailBreak devices were so popular was because they were plug-and-play without opening the PS3 and also at the time Custom Firmware wasn't available either.
