E3 flasher Successfully Downgrades PS3 From 3.72 To 3.55 Video

Today while checking out e3-tech.net I stumbled across a video they uploaded the same day that Sony's official firmware 3.72 was released. The video showcases the E3 Flasher successfully downgrading a PS3 running Sony's latest firmware v3.72 and therefore the ability to dual boot between custom firmware and official.

And another BIG news is E3 will provide NOR FLASH CLIP free in 3K limited version !
so all slim and parts of fat console no need solder for downgrading .

NAND FLASH CLIP also fininshed, will be available in coming new E3 FLASHER NAND version.

E3 flasher shipping date will little delay because of adding extra clip.
we will inform shipping date in next few days ,sorry bring inconvenience for E3 user.

So despite previous speculation that the new firmware update was targeting recent downgrade methods, we can safely say that the E3 Flasher is still a viable downgrade & dual boot tool. I for one wonder if Sony could block this method with a firmware update or have we finally found a way to have the best of both worlds?
