turning off is bad flash in normal case so yeah like already posted he must halt the PS3 and go from there, he got all he need to restore, some info about a CECHL04 brick on my end(not messed arround after initial bad flash/downgrade) was fixed by using the "original" E3 way = bkpps3.bin+e3_downgrade.bin+the logfile = connect PS controller and FSM install rogero 3.7 etc....
i think we helped enough so far, in the end he's the one that need to fix it, would be nice to have a teleport? machine so we could fix it
anyway..wish him luck and sure it wil unbrick if doing this properly
