Ok, because I am not patient at all, I went to http://192.168.2.1/ (Belkin stock UI), logged in and accessed http://192.168.2.1/ver.htm and set "firmware header checking" to 0 and applied. Then I again went to 192.168.2.1 and flashed LEDE 17.01.2 via firmware update menu. After upgrade and router restart, I released and renewed IP address and accessed 192.168.1.1 and LUCI webpage appeared. So answer to my question is yes, Belkin F5D8235-4 v1 can be flashed to LEDE via Belkin web UI and it is very easy to do it.
