so I've been trying to flash my new s7 slim with the south african firmware located in the official slim firmware post, and it just will not happen. I created a folder called "dload" in the root of the device and copied the UPDATA.APP and unlmt.cfg files into it. I power off the device, put the SD card in and power it up. It just loads like normal and never even attempts to do anything like flashing. I'm using an 8GB Transcend MicroSD card. Anyone have any advice?
