How are you trying to enter test mode? With sd card and testmode.key or by button presses?

Try pulling radio fuse or power (both yellow and red wires) for 10 minutes or so.

I just tried it! I did not work for me at all! SO this is where I am,

Cant enter testmode both with an sd card or USB through Ipod cable

I also cant enter test mode through holding home and track forward and back sequence. 

What other options do I have?

Thanks in advance

Try this:

keys combination to get into test mode manually by following: remove sd

card, turn on ignition, keep home button pressed and press previous,

next, previous, next and so on while keeping home button pressed until

the unit restarts, it should enter testmode.

In my case it does'nt working now

I am trying to enter using a sd card, how do I enter test mode another way? You mentioned something about buttons? what is that process?

In the process of trying to install new maps x930bt, deleted the wrong files during copy and pastes process of test mode. After I messed that up, the unit tries to install and update and fails, the message states ''program update failed'', restarts, and tries to repeat the install process again and again and it fails every time. 

I can no longer enter test mode. What do I do? Any constructive help is greatly appreciated. 

Same problem with my x930bt, deleted the wrong files during copy and pastes process of test mode. After I messed that up, the unit tries to install and update and fails, restarts, and repeats the install process again and again and it fails every time.
