Hello, I tried to upgrade my firmware for the first time under my K2. I use the file located in the folder K2.20190420.V0.49-USBreader I upload in the sim card under the root
The device flash like the video instruction show, but it is only doing this since more 30 minutes now. I think it is just looping while since I have doubt that is take more than 30 minutes. Someone have suggestion to help me?
Thanks in advance
