My brother sent me a Lumia 830 (Special/Gold Edition) AT&T Unlocked as a gift. I'm on the release preview ring currently on 10586.420. I only
used this phone for 3 weeks.
I was on a festival last night and when I changed from front camera to rear camera it suddenly showed "Something went wrong". Error code 0xA00F4271(0XC00D3704). The error started showing after I updated to 10586.420.
When I try to turn on the flashlight, the phone completely freezes. I can't lock the screen, close any apps, nothing happens. Only way to make it work is by removing the battery to reboot.
I tried soft reset, hard reset, changed camera permission, uninstall and installed camera apps. Used camera 360, pro shot and many camera apps, still I am unable to use my back camera. Although front
camera works perfectly.
I upgraded to Redstone build to see if my camera gets fixed but it failed to solve my problem. So I downloaded Windows Phone Recovery Tool and rolled back to 8.1 and the camera error still exists. Now I'm stuck with this problem.
I am from Bangladesh and I don't have any warranty. I went to Nokia Care and they didn't even touched my mobile when they heard that I have no warranty. They simply asked me to give them $80 to change the camera module. I am not interested in changing the camera module with money. So is it software issue or hardware issue? Many said it may be the faulty batch. But Special/Gold edition released like 7-8 month after the normal edition. So it is very unlikely that I received the faulty batched phone.
Please help me here. Thanks in advance.
