Unlock with GEVEY help!!

[dyoo20]

I performed all the steps on the youtube videos to perfection, and almost completed the task.

After everything, I got about 5 bars, but it didn't say T-Mobile next to it. After about 15 seconds, it suddenly said invalid sim!

Anyone know what caused this or how to solve this problem??

Thanks

If you did indeed follow the steps correctly, at last you should be on the Setting screen and toggle the airplane mode on/off, if it worked, "Tmobile" would show as the carrier instead of "no SIM", did it say that?

followed everything correctly. I finally got it working..

When they say 'don't mess with it', they really mean don't mess with it.
