Basic phone shows msg. about firmware/IMEI tampered


    Hi, everyone. I have a T-Mobile Prepaid Samsung T199 basic phone. I just powered it on and it displayed this message:


    Firmware/IMEI on your Mobile phone tampered !. Please contact T-Mobile customer service center.


    I tried powering it off but it wouldn't, so I removed the battery. I then replaced the battery and powered it on again and got the same message. I removed the battery again and also removed the SIM, then I replaced the battery (but not the SIM) and I powered it on again and got the same message again. I guess I have to take it to a T-Mobile store, huh? Would they be able to clear this message, though? In case it matters, the phone is out of warranty.


    Thanks in advance for your replies.
