Halium on Samsung Galaxy Tab 2

When flashing halium.boot to the tab 2 (using heimdall as its size is too large to flash from twrp) and then booting, it goes to a "Power Reset or Unknown Upload mode"
Hybris-boot does work, I can ssh but no display and cannot get much info with it anyways :(
I got dmesg from hybris-recovery if that will give some clues - https://pastebin.ubuntu.com/p/QJQ8QgFKWm/
