I would to use OpenWRT but i maked a silly thing, I've install OpenWRT like it explained in the wiki under the section "Archer C50 v4 installation instructions" i decided to flash the pre compiled boot.bin from the dropbox .zip that worked well, but then i done the next step "Download tplink_C50-v4-squashfs-sysupgrade.bin for OpenWrt 19.07.x stable. You can use LuCI to install the sysupgrade.bin file." after this i didn't have anymore LuCI, then i connected me with ssh to my router and tried to install LuCI but the package wasn't found even after opkg update, then I decided to "rollback" to my first installation with the boot.img(because the most things worked there), so i pushed the boot.bin to my router over scp and made sysupgrade --force boot.bin (Now I know it was silly) and now my router goes on but after 2-3 sec it goes off and turn on again(endless).
Please Help Me.
Thanks in advantage for any help.
