Firmware flashing via sd card

ArduCopter Copter 4.5

Hi,

I am trying to flash firmware via an SD card. To do this, I first flashed an older firmware version (Copter-4.5.0) and updated the bootloader. I then copied the new version .abin file (Copter-4.5.3) to the SD card, placing it inside both the APM folder and the parent folder.

However, after power-resetting, the board is not flashing the new firmware from the SD card. I waited for 5 minutes and checked the file name, but it hasn’t changed. Am I doing something wrong? If so, please guide me.

Thank you.
