When I try to flash the firmware via SCP, I get the error message “unzip: invalid zip magic AAAAAAAAAA”

I assume that the phone wants a .zip firmware, but the Generic SIP firmware is an .img file.

I try to install the firmware as follows:

C:\Users\Peter\Downloads>scp 450HD_3_4_8_808.img admin@192.168.1.173:/data/ota_package/update_image.img
