ZTE 990g will not turn on Debugging mode

view story

http://androidforums.com – I can not get get my phone to go in the Debugging mode. I connect it up and no little bug appears in the Status bar it just offers USB storage mode, with the USB icon in the status bar... ADB on the computer doesn't even see it. It worked just fine until the WiFi quit but, thanks to Tech support, I got it back. The poor guy at Tech had no idea what I was talking about, Debug Mode. I've tried this on two different computers. I'm using Rom 1.3 in the Setup guide. I'm going back to the stock rom. This 1.3 rom seems buggy to me. Then again, I could be the one that is! Thanks ahead for the help (General)
