A couple of services for unlocking locked devices rejected me because my device doesn't prompt for unlock code.

When i insert non supported sim card the device reboots and that's it, no prompt for entering unlock code, nor when i inserted another sim.

I tried with force USSD code to show me the unlock menu but that doesn't work either.

I tried waiting for the battery to run out. The phone slightly overheated, then I charged it again and the moment it had a little charge, it started doing this again. The On/Off button isn't stuck or anything alike.

What do I do?

when he gave it to me he said to me that water has been spilled(a few months ago) and nothing worked.

i gave it to a repair shop and they said that they cant repair it but after pressing a button at home after a few hours sound began to work. and the display too can be seen with a torch(no backlight).buttons too can be pressed.torch too works.

yersterday i noticed that when pressing the power button (to see lock screen) the backlight works well(as normal) for about half a second and dims again.

anyway to fix this?.

help is highly appreciated!

my device(Xperia m2 dual) after unbrick, don't work sim card slot 2nd.

How to fix this problem?

I have been over all the connections and the phone switched on and still recognises touch but just cant see anything.

After a sock the the vibration motor stopped, and it works for a small time after clicking with my fingers on the mobile and then it stops until i click again.

and the loud speaker is working but it's volume is too much low, i think one of the channels ( right or left) have just stopped working.

can it be repaired without replacing the motor/speaker ? (for example , the sock made the connectors of the motor disconnect , so reconnect them again... )
