I've followed that route & got no entry inside the Plugin, but a few errors would appear whilst installing..
[ Your Device not supported (Ask US about it)... ]
* opkg_lock: Could not lock /run/opkg.lock: Resource temporarily unavailable.
* opkg_cmd_exec: Command failed to capture privilege lock: Resource temporarily unavailable.
* opkg_lock: Could not lock /run/opkg.lock: Resource temporarily unavailable.
* opkg_cmd_exec: Command failed to capture privilege lock: Resource temporarily unavailable.
And then
Before clicking on any Plugin, this error appears :
