How to push a firmware on a CPE

Hi,
I’d like to push an npk file to update the firmware of my mikrotik CPE.
But when I upload it as an firmware update, I got the error:


“Too big file. Is it really XML describing MikroTik packages? URL: http://genieacs.netalis.net:7567/tr069-client-6.47.9-arm.npk
I don’t know what to put in my xml file. What can I do to upload this file?
Thanks in advance

See this: Manual:TR069-client - MikroTik Wiki

see my guidance at TR069 with GenieACS v1.2.3 (Step-by-Step) - MikroTik
