hi,
Sound like you need to look at your Keyboard mapping files, easiest way to fix this is to use Motorola System Configuration Manager - Downloadable from the Motorola website.
If the unit need to be restored to factory defaults, than a fast way is to run the Clean boot files from the SD Card also downloadable via the Motorola site - search for 'MC9090 Clean boot'

The Motorola MC9090 can have different keypads attached. If you do change the keypad for any reason for example go from a 53 key to 43 key layout the terminals must be cold booted.


To cold boot an MC9090 running Windows Mobile 5. Partially remove the battery, hold down the On/Off button, the trigger and reinsert the battery. When the orange light on the keyboard flashes release the on/off button and the trigger.

If the on/off button or trigger is held down longer than required this occasionally causes the terminal to get caught in a warm boot cycle

If the device is still not giving the correct key output it may have a faulty keypad.

plug a car charger or mains charger into it and get power back to it before the battery gets low :D

I know it may be a little late now since you're question was a couple months ago, but I have had this problem with some 9090's before too where a warm boot (holding the power button down) will not bring them up, but a cold boot always does (unless of course it truly is defective - that's not usually the case though).

To do a cold boot, pop the battery out part of the way until it "catches" (you'll know what I mean if you have an MC9090 and try it). Then hold down the trigger and the power button simultaneously while pushing in the battery all the way. Once the battery has been pushed in, release the power button and the trigger.

This should cause the MC9090 to boot up fine. Make sure you release the trigger after doing the steps above. Sometimes people don't do that, and this causes the MC9090 to go into an infinite warm boot where it just continuously reboots over and over. The only way to get out of it is to cold boot again, but this time release the trigger in time.
