See dejavuln-autoroot for a simpler exploit that works on webOS 3.5+ TVs (i.e., models from 2017 and later). It is unpatched as of 2024-04-21 and does not require Developer Mode or even a network connection—just a USB drive.
Otherwise:
- If you have a webOS 5–8 TV with old enough firmware, WTA (which does not require Dev Mode) will still work.
- If you have a webOS 4.x TV, you can also try CVE-2023-6319, which is unpatched on the latest (final?) firmware for webOS 4.0 (2018) models.
- While there will eventually be fully software-based exploits released for older models, they can currently be rooted via NVM.
