Hi there. 

I'm trying to get the UPEK Fingerprint work by updating ControlVault firmware. 

During firmware update, I can see that Dell ControlVault changed from w/o fingerprint to w/ fingerprint in Device Manager. 

However, after I restart upon successful firmware update, the controlvault seems bricked. It shows Dell ControlVault 2 in Device Manager. 

I then try to reperform the firmware upgrade in DOS environment and I noticed that it reports that ControlVault is in bootstrap mode, and no SBI image is loaded. No matter which firmware i use and what method i use, the SBI won't install onto the BCM5880. 

I hope to get advice on how to get ControlVault back to work, so that at least I can use the Contactless Smart Card which used to work previously. 

Best Regards. 

EDIT : my device is Precision M4500 running Windows 7 Pro x64 (clean install).
