I have an 8310 from SUNCOM that was was antenna locked? I have removed old software and reloaded new software without vendor info. Everything loads fine, but when I insert SIM card it gives SOS in red at top right. I have changed service providers on plenty of BB's before, but have never encountered this problem. Any ideas?
I am just trying to get his phone back up and running. They sold him some piece of junk phone that works like crap....Thanks
