No "-I" (capital `i`) flag in traceroute

For Developers
1

The standard traceroute package lacks the "-I" flag, which would cause the utility to send ICMP packets instead of UDP. This flag exists in traceroute packages for other operating systems (Debian, Ubuntu, etc.). Is there any way to install an extended package that includes this flag? Please refrain from suggesting using MTR.

Hping3 will allow using icmp... but the default busybox traceroute does not have icmp tracing enabled as far as I can tell. If you need it, you likely can build your own firmware enabling that feature for busybox.

you'll need the full version. This should build it an override busybox ..

 This is the full implementation of the traceroute(8) utility for Linux.
 Unlike the BusyBox version, it supports ICMP (-I) and TCP (-T) tracing.

I have confirmed it builds ...the rest is up to you
