Hi,
I cannot connect to the internet after unlocking boot loader. Phone was already rooted and have dual recovery. I tired to connect wifi and 3G, despite it CONNECT, no data is sent or received.. Rebooted multiple times. no change.

I tried to unlock by bootloader by official method. So here is what i did:
1. Switched off the phone and connected via usb while pressing the vol up button.
2. Blue led appeared and detected by pc (running on Win 8.1 64bit with flashtool installed)
3. opened cmd and checked for connected device.
IT SHOWED NONE! :(
4. removed usb cable and connected again by holding vol+
STILL ADB DEVICES SHOWS NO CONNECTED DEVICE
5. Device Manager shows something with "Sony s1 boot ..." on android. Still adb shows no attached device.So I deleted the driver, again installed the drivers from Flashtool for my device. Selected manually, (i dont recall the driver name exactly, but its with "s109..." ). After the drivers were successfully installed, i again checked for devices and STILL I DONT FINE MY DEVICE.
6. Again i reconnected the phone.
7. typed the unlock command ' fastboot -i 0x0fce oem unlock 0x<myKey> ' and I got 'OKAY'.

After that I switch on the phone and wondered to see that the internal memory is formated! ( is it suppose to happen when unlocking the boot loader??) And I have to setup, like a band new phone.
Checked the bootloader unlock status. It shows YES.
Sorry I am new to these things. I tried to google and search for similar thread here but I think are different from what i am having here.
