(adsbygoogle = window.adsbygoogle || []).push({}); I have three ps3 so i wanted to test it out in 2 of it, i have downgrade so bricks aren't important.
I wanted to do a experiment, and this is why, i have 2 FW on my iMac, and 1 is 169 MB (older) and the other is 170 MB (newer), and i thinked the md5 change and possibly that is the brick reason.

Firmware installed in:

PS3 SLIM 320 GB
Old FW: 3.55 OFW 169 MB
BRICK?: NO

PS3 SLIM 160 GB
Old FW: 3.55 OFW 170MB
BRICK?: YES, PS3 doesn't turn on. Downgraded Succesfully.

So, you will see, possibly is luck, possibly is that the reason of the brick.

i bricked my console eairier 80gb relese model. switched HDD downgraded and now installed new CFW weird or what. what would the hard drive have to do with me getting bricked anyone know?
