3310-security data failed

[windbreaker]

I always encountered this kind of problem when you open the cellphone signal will come out after 3 secs. no network and auto shut off and when i read the status using winddp it say SECURITY DATA FAILED. Is this a software problem or hardware? Help....

I think it's a software problem (Faid checksums are not maching the calculated checksums).
First - try to Update Faid in Nokia Tool by Rolis (1.7b or 1., Knok22, nc_calc or something simmilar.
If this wont help you try to use logger and faid calculator and after updating other checksums try Nokia Tool.
If that will not help either try to reflash the phone using good full flash (MCU+PPM+eeprom).
The text 'SECURITY DATA FAILED' doesn't say enough, but that's my suggestion and maybe can help.
Before doing anything I suggest you to do a copy (full backup) of yours flash.
