it will be persistent but latent.
e.g. after a time period of "unable to successfully implant in OS"
it will quit trying. or maybe not! unknown unknowns, etc.
or maybe not! large variance between paid proprietary LE only exploit kit
and truly exceptional nation state intelligence and exploitation techniques.
you should use the BIOS adventures below to find out.
[the TAO-related Snowden leak details are informative]
mobile implants are observed "geofenced" by tower or stringray. by
activity of other apps. by network traffic. by time of day, ... this
is a long list :)
your router(s) are trash, now. (maybe you can directly flash, like
BIOS adventures below?)

capture is good first step, and if not in this instance perhaps the next.
capture is always useful! (via independent and not networked device)

you can open up and search for BIOS flash chip. if you're lucky it
will be a 3.3V SPI flash chip in 4 or 8MByte (they often measure in
bits, too, don't ask me why).
you can use a rPi to do it, even!
that last is an SPI chip in my pair of ASUS B43J laptops - it is nice
to have a pair, saving the good one, in case something like this
happens. the stealthy stuff will betray power consumption and forensic
flash image digest values (sha256 of specific flash regions)
remember to adjust configuration parameters for SPI support if using the rPi.
i highly recommend the Shikra as well, however, it requires postal CUSTOMS. :)
this is just the start, of course, but enough to give tells...
