@Lazar-Demin sorry for the late reply.
I meant was that I want to have Openwrt or LEDE but without the OnionConsole or other extra software.
As I could see LEDE project is only available for Onion Omega 2 and Omega 2+ but not for the original Omega. Maybe I didn't search on the right place but I couldn't find anything related to LEDE for the original Omega.
I also try compiling but it failed at some point following this guide: https://wiki.onion.io/tutorials/cross-compile on the step 6a.
Any help would be highly appreciated.
