- Flash a decrypted firmware image from D-Link. Decrypting an firmware image is described below.
Decrypting a D-Link firmware image:
- Download https://github.com/openwrt/firmware-utils/blob/master/src/dlink-sge-image.c and https://raw.githubusercontent.com/openwrt/firmware-utils/master/src/dlink-sge-image.h
- Compile a binary from the downloaded file, e.g. gcc dlink-sge-image.c -lcrypto -o dlink-sge-image
- Run ./dlink-sge-image COVR-X1860 <OriginalFirmware> <OutputFile> -d
- Example for firmware 102b01: ./dlink-sge-image COVR-X1860 COVR-X1860_RevA_Firmware_102b01.bin COVR-X1860_RevA_Firmware_102b01_Decrypted.bin -d
