and install it from xmb should be fine, just make sure everything is working good and accordingly after you install the firmware...
would also like to point out that e3_downgrade.bin patches NOR for 3.55 downgrade, which is why your 3.56 based system had syscon panic/shutdown in 2-3 secs
once patched correctly , it worked fine.
any other questions reguarding this? lol
I also have another ps3 that goes off is 1 a 2 seconds.. lol...!
But that can't be fixed by me.. someone spilled drinks on it..!
is it another 3.56 based system?
hmm is this urs? (file in the quoted post!) that's why, then again u have it fixed..

weird, cuse the dump has "metldr"(1) shown and the validator reports "metldr2 - 3.56"
good thing u have the other fixed, this one can't be downgraded, although the dump is valid!
