I am using a Sony Xperia Neo L (MT25i). After updating the OS, my phone not registering to 2G (GSM only mode) network. It works perfectly with 3G (WCDMA only or WCDMA proffered mode) network. While searching for network I can see all the 2G network. I try changed my SIM, but for all the SIM its the same. While googling many are reported this issue, but couldn't find a solution. I don't know whether I am posting this on right place. Since it happened after the OS update I am posting it here. My current Android version is 4.0.4

Update I am from INDIA and my baseband version is 8x55A-AAABQMAZM-203028G-87. Does any one have other baseband on Neo L (MT25i)?

  • I think this is probably caused by updated baseband. Can you flash older baseband only?

Reset to default

As it seems you have tried resetting to factory defaults and re-flashing same update, I believe the causes might be caused by updated baseband. I would try reflashing different original firmware. You can also flash baseband only via flashtool so maybe it might be worth trying to flash baseband from the firmware that worked. YMMV.

You can find links to download FTF (original firmware) for your device:

Try flashing the latest ftf file from here. If you are already in .631 build try flashing the baseband alone. (Try downloading the ftf file again and flash).

Simple solution, just reflash radio for your device and it should work. If not contact your provider.
