hard to tell what's the issue, but you did unlocked the bootloader of your device

did you flashed a custom ROM at any time? what else did you do with the unlocked bootloader?

Re: can't connect to 3g network

I was supposed to flash custom rom but I couldn't not flash custom recovery so I haven't flashed custom rom
That's why I created other thread for custom recovery help

well, it's hard to tell if it's a hardware issue or if something wen't wrong during the flashing process, you might want to post on the forum with the custom ROM, I'm assuming that it was the XDA Forum?

it will be malware and either flashing the phone with EMMA, or Xperifirm or Flashtool or XC, should take care of it.

Re: can't connect to 3g network

If the malware is in sd card
Flashing a phone is nothing to do with sd card right?
Then again after flashing malware is affected to phone from sd card

Something really simple you can do is remove the SD card > flash/repair the phone > check again.
