Network signal drop issue xperia s

[zeshamzesh]

I used my phone for about one year. few days ago my phone dropped network signals and started draining battery. I tried to reset and factory settings many time but problems is still there. I even tried to unlock bootloader (without knowing and updating rom) but nothing is changed. I am also unable to update my phone because i have unkowingly unlocked bootloader of my phone although i have not updated the ROM , Please Help resolving the problem

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I would suggest that you first of all try with another SIM card in your phone to see if the behavior may be related to network/SIM card.

I have already, used these options, changed network sims, changed the old sim with new ones. The network probably is working near the network towers but as i go farther the signal drops. I have flashed twice, factory reset thrice, format my internal memory, enabled GSM only option, but nothing happens good for me. Twice i visited to see repair shop but when i reach there signal works well (proably due to the vicinity of tower). When i search the network it shows the available networks with home network but when i want to register it shows a error message. thanks for your support.

In that case you have tried the most things you can do. Do you have the possibility to try with another SIM card from another service provider? 

If not I suggest that you raise this with your local Xperia support team to see which options you have to proceed with this.
