Display MoreWhat is the name of the plugin you installed? It might be possible to delete it (not the same as uninstall). This does not guarantee to stop the green screen.
Plugins are normally located in either:
/usr/lib/enigma2/python/Plugins/Extensions
/usr/lib/enigma2/python/Plugins/SystemPlugins
Do not delete things unless you are sure.
At some stage, you will have to resolve why you cannot flash your receiver.
I also found "Configuration" option in this program called Advanced IP Scanner. How can I change the configuration to make the green screen go away? This is the green screen that I got last time, do you see anything that could be the problem?
