How many more times do you plan to request unlocks here? It doesn't seem to bother you that you are abusing the rules. Just in the last month you have a lot of requests here, I haven't counted them exactly but it seems to me that you and a few other people really don't feel like you are overdoing it, I am giving you a very official warning that this will not continue like this. If you don't stop yourself, I will.

I am deeply sorry about that... I am not always happy to request for bios unlock for dell 8fc8 .
just that the last one i try doing myself using the instruction giving to me by sir Marcus, the process works fines,
but after putting the unlocked dump,system powers but did not display... thats why i have to drop it here..
I AM REALLY NOT HAPPY TO ALWAYS ASK FOR HELP..
IM DEEPLY SORRY ABOUT THAT, for breaking the rules... MUCH LOVES

1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode
try comparing the files its always 4 difference's then clearme.
make sure to clearme the dump after modifying the lock.to work properly. you can do it yourself. just try so that next time you can do it on your own.

Anyone can help me clear ME this bios dump. Sound is good but it will be no output device after I install Realtek audio driver, the driver Intel® Smart Sound Technology (Intel® SST) OED is error (code 10). I tried some bios dumps here but no display.
