I've extracted the bootloader and modem form the T715 firmware and made them Odin flashable.
Still haven't tested it but It should work on the T715Y
I've also made this Rom with android Kitchen so you'll need a custom recovery to flash it.
So the steps are simple
1. Flash sboot.tar.md5 through Odin on the BL tab
I believe you don't really need the modem
2. Flash the tab2.zip through a custom recovery.
Again I haven't tested this so I don't know if it works
