No man if you got a good extraction...with a valid key you should be good to go...your only missing one step....JF is notorious for Half-bricking (for lack of a better term) Lite-on drives....have no fear though
Cofree has made a TUT that everyone who intends on flashing a lite-on should have a look at, as it's only a matter of time before they will need it. You will have to build a dos-flash boot drive (just like for iPrep) then insert your Lite_cfw.bin...bam you will be good to go. You can find it here..
