Hi,

I would suggest that you do a software repair using a PC and PC Companion.

In PC Companion you press start on "Support Zone" > Start on "Update the phone/tablet software" > "Repair phone/tablet" (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

The software repair will remove all data stored in the phone so don't forget to make a backup in PC Companion before you try the software repair. You can do a backup using the Backup & Restore option in PC Companion.

Tried pc companion 6-7 times and got many error.. Finally i manage to reach till end when it ask for turn off phone and connect while holding volume down button. I did it and got update engine error 2003.. I don't understand why give such bug full update that just for get 2g or 3g people need to suffer this much! Sony plz fix this. Started feeling like that was bad idea to buy xperia 2 weeks ago.. 😥

@Shubham54

Is your phone compatible with your network's 3G frequencies? is or was your phone locked to another carrier/network branded?

@Shubham54

Can you check if you need to download the internet settings from your network provider again (or manually set them) ?

I remember i had that once, after i reset the phone (not my current sony phone) just to reinstall same OS. At home i didnt notice it as i was connecting to WiFi. Only when i went out of the house , and thats when i thought my data is not working. All i had to do was download the settings.

Just a thought.

@Shubham54 To my knowledge error 2003 indicates that the phone's software has been modified. Is this something that you know has been done?
If the phone's software has been modified you will not be able to use the update feature of our standard programs.
