Hello, Thank you in advance for the help. This morning I tried to go on the internet but the phone just blacked out for 30 seconds. From then on I didn't have a signal. When calling or send texts my phone said "no mobile network available". Later while on wifi, my facebook account was hacked. I don't know if these two events are related. My phone is in fairly good condition. The software can not be updated. I did a hard reset, but the signal still has no connection. Also, the imei is not available. Please let me know what I can do, because I already tried changing the network to LTE/CDMA and dialing the *#06#. Thanks.
