Hope somebody can help me.
A few hours ago (about 10pm UK time) my GS2 suddenly lost all signal. I tried going into Settings > Wireless and Network > Mobile Networks but I just got the message Insert SIM card to access network services.
I am with Three UK and have tried both my SIM cards, but neither work. They will work in another phone though.
I tried resetting it but thats made no difference, and now I wish I hadnt done it as Ive just noticed that half my contacts are lost! They arent showing up in my gmail account for some reason. It used to sync them automatically.
Theres definitely a problem with the phone itself anyway. When I try to access the IMEI by dialing *#06# it comes up blank, and under Settings > About Phone > Status many things come up as Unknown.
Is there anything I can do? I cant think what brought it on. The only thing Ive changed on the phone recently is update the firmware, and that was an official version, and several days ago anyway.
