I have an SM-T355Y (gt58ltedo) Tab and I was keen to get this compiled as well.
I tested the recovery you sent. It does boot properly. There is some issue in the zip path due to which it does not extract/ install directly, but when I navigated through the structure and took out the recovery.img, it flashed fine with TWRP and I was able to then reboot to recovery using this.
Hope that helps.
Waiting with baited breath for a LineageOS for my Tab. ♥
