Having problem to upgrade phone load (CM 4.1 (3) sr5b)
I'm upgrading the phone load on 7961 from 8-2-2SR1 to 8-4-2S. The error message on the screen is "error" without any specific description. I tried to unzip the phone load files and put them under the tftppath folder, the another way is to run the exe file to update the phone load directly.
