Xbox Error 21

I unlocked my hard drive with slayer installer and now i can't lock it again because I don't know the HDkey can anyone help me. It boots straight to the service screen Error # 05

 

I think you could try xbins their might be a program that tells you....but i honestly don't know .......umm i have evox and i can lock and unlock my hard drive with out the HDkey

 

I unlocked it with evox and now I can't boot to the dash to lock it again.

 

what screen loads when u boot?

 

The problem has now changed I found out how to lock my hard drive using my computer, but now i can load my evox dash again (softmods) but I am getting Error 21 on my xbox the last thing I did was copy the c and e drives from a friends xbox because mine were completely screwed I am think that there are files that I need to change or something so my xbox will load the M$ dash again. I can load it when I use evox but if I turn my softmods off (so I can use XBL) then it loads the service screen.

Wow I regret doing everything I have done. I just ordered a mod chip so I can completely due away with all of this but I would still like to get it working so I can use XBL. (unless there is a way to log on XBL with your modded evox dash)

 

yaeh the same thing happened to me i went to some screen and i clicked unlock and know when i try to get to my dashboard it wont let me their is an error 21 w/ alot of chinese and crap i cant find out how to get to my dashboard and lock it

 

Error 21 is not the unlocked hard drive code, error 5 is, to lock you hard drive again though you can go to your backup of your dash and open up the HDDkey file and copy your hard drive key. then download hd lock and make a dos boot disc with that file on it then put your xbox hard drive in your comp and run the boot disc. when "A:" pops up type hdlock.exe and when it runs just put in the code and it will lock it. Then re-install the hard drive to your xbox and your good to go.

 

i think your hd isnt formatted correctly. Either that or your HD is full which i doubt
