I also believe its what Barry said about the last user, but don't worry you can fix it 100%. Because you have a E3 reader.
I have bricked my ps3's now over 9 times, I kid you not, and the reason for this is I love trying things out, and believe it or not I have just bricked another one lol as I type this post with a linux project, but it so easy to fix as long as you never go over 3.55 and you work with known safe tools and pups.
Try this bud, When the light turns blue quickly remove the ac power, don't let the ps3 hard drive come on as it will not work. then downgrade to 3.41cfw, then upgrade to 3.50ofw (this is a must) then upgrade to 3.55 ofw and lastly install Geo's 3.55 patch or rebug.
The power removal timing is impotent, and the 3.50 ofw before 3.55 ofw also.
Any other help needed, just ask.
Something I forgot to add is, if you downgrade to 3.41 and wish to stay there, then downgrade again to 3.15 ofw and then backup to 3.41 ofw and jailbreak, or create your own 3.41 cfw like many of us are doing now.
