i would have flashed a backup image with CCCam and TSPanel already installed in the image,there is plenty out there.
look for addons then manual install IPK file,and press ok if the file is in tmp you should see it,providing you have sent the TSPanel.IPK file to tmp unzipped.
just would like to add here CCcam_2.3.0 merlin ipk , in case if u still cannot install from Ts panel , unrar , send ipk to /temp , install it manually by telent or by Tspanel from ( file explorer then choose ipk in temp & hit install) , reboot
