O.k., after looking at the FCC pictures, which are not detailed enough
to read all of the chips, it becomes clear that they're using a
similar, but significantly different PCB for the TL-WDR3500 - so you
really should make high resolution pictures and check bootlog/ GPL
tarball before risking anything. While there still is a small chance
that the differences are small enough that OpenWrt might "just work"
for this device as well, it does look like there is a different
solution in place for the networking switch, so it's more likely that
some more involved source changes might be needed.
