That partition is in READONLY flash device. So you cannot write it.
You needed to rewrite complete partition with changes.(Like older exe.dsp)
Please read Manually Flashing wiki page.

I got the same libPluginTvOEM.so missing when I tried to manually start exeDSP within telnet session. After a while I found the libraries (under the widgets or something like that) and added them to LD_LIBRARY_PATH. Then exeDSP started but it failed to function properly. Dunno if it's even possible to start it successfully from the telnet session.
