ADSL firmware upgrade on 887 router

We cannot find instructions on how to use the latest 4.0.18 ADSL firmware on an 887 router. We have downloaded adsl_alc_20190_4.0.018.bin from the website and copied it to flash, but cannot find any instructions on applying the firmware. Tried rebooting but made no difference.

You shouldn't have to do anything other than copy the file into flash and then reboot. The router should see the .bin file in flash and use that instead of the one built into the IOS.

Assuming the 887 behaves like the 877/857, the file has to be renamed to:


and then you reboot.
