"Phone restricted" error
If the failure message "Phone restricted" (notice: it depends on the language used) appears on the display,
it is not necessary to exchange the flash or scrap the phone.
The solution is just to rebuild the SIMlock. After this, the message will disappear. (see also SB 030).
Keypad faulty
If one or more keys are not working, disassemble phone and check resistance = 0Ω between keys on same colum and
row with ohmmeter.
For example: key 7 is not working:
Check row D2
keys "1", "4", "7", "*"
Check colum D5
keys "End", Down" 7", "8", "9"
If between two keys the resistance is approximate MΩ, change PWB because of broken connection.
If all resistance = 0Ω, remove Z300 EMI-Filter and measure the connection between keypad and red
marked solderpads from EMI-Filter. If connection is not ok, change PWB, because of broken connection.
If connection is ok, check with ohmmeter the resistance between ground and blue marked solderpads
resistance around 2MΩ
If resistance is lower than 1MΩ or higher than 10MΩ, scrap the phone, because the UPP D400 is faulty
and not changeable.
