My camera can not start after I upgraded it
I have upgraded my NX300 to firmware 1.45 by using Samsung i-launcher but then, I have been faced many problems especially lens (18-55cm III OIS) could not work properly. I fixed the lens error but I could not fix the autofocus by pushing trigger button. Some buttons on the body begun to work wrongly etc. I tried other firmwares to solve out the problems but I could not be successful.
At last, I downgraded it to firmware 1.0 which was original one but now I could not open the camera. It is totally not responding such as dead battery though that it is fully charged.
Is there any way to hard reset it? Or any other solutions to get rid of it??
If someone can troubleshoot my unfortunate problem I will be really really apreciate it.
Thanks in advance.
