Question about Cell Phones
Nokia 1200 displays test mode
To exit test mode, turn off phone.
Press *3001#12345#. Scroll up 1 to FIELD TEST (some phones may say NET MONITOR instead of FIELD TEST) and SELECT. Scroll to ENABLED and press OK. Turn phone off and then back on. Signal strength is the upper or lower left number. After test mode is enabled it will stay in your regular menu. To easily get in or out, press MENU, up 1 FIELD TEST and SELECT or OK. Dial 00 to get out and 01 to get back in.

Having the same problem, ah but the phone is already off and won't turn on. If I disconnect the battery for a while maybe an hour and reconnect it works fine. However if I try to charge the battery with the phone on (which it will not do) it goes into test mode again when I turn off the phone and turn on again. If I try to charge the battery with the phone off it just goes into test mode. If I take the battery out and wait a few minutes then put it back in it just gives me test mode and no buttons work. But as I said if I take the battery out after an hour or so it will work again . However it still will not charge.

Test mode is used by engineers to repair particular problems with mobiles. It would appear you would need to take this phone to a mobile repair centre and get them to fix the s/w on it.
