need help with mms

i made a mms succesfuly with total newbi installer and used it and my pandora to downgrade to cfw but now im bricked and i need to make another mms so i tried using total newbi installer again but its not working(i tried using a fat and a ms reader neither worked)

What exactly is happening when you put everything in?

Have you tried flipping the power switch to the hold position then holding the L trigger while you place in the battery until the green light goes off then take the battery out flip the switch into its normal position and hold the l trigger while puting the battery in place.

I find with a lot of slims you need to flip the switch to hold before it will actually work.

oh i thought that was for phats only. i put the mms in then the battery auto turns on i get green light but nothing else only black screen and i wait then press X but i get nothing no lights or any thing. but i will try putting it and hold. hopefully i can unbrick it

okay it didn't work I'm still getting a black screen(not a light up black screen):x
so i tried making a new mms using total newbi installer through my brothers phat i got a error message saying that target1 is not physical drive:evil:
then i tried using a ms reader still same message does any one know another way to make a mms or to stop total newbie easy installer from getting that error?

Did you format your stick before using total newbi installer? If not you might wanna do that before trying to use the installer.

I noticed you said you were holding X...Usually you have to hold the L trigger while you place in your battery and keep holding for about 5 seconds after the battery is in for it to boot into the service menu.

yay it worked i dont know what happend but know im unbricked i did the same stuff i did before but the pandora worked
