Went to Uniden's website to update my BCT15 firmware from 1.03.04 to 1.06.00. According to their website you dont need a registration key to update to this firmware. When I went to update, the firmware uploader told me I needed a registration key for this major update. So I tried it without the key and it didnt take. So I repeated the steps again. NO GO!!! Now when I turn my scanner on the back light just blinks off and on! Tried to reset my scanner but cant even do that. Wait which seem like forever to talk with Uniden's Customer Support, so I left my number still havent heard back! Seems like the scanner is lock up can someone help!!!
