Warnings

What you do with this information is your own responsibility. If you brick your TV trying this, it's not my fault. You should probably have some electronics experience if you want to attempt this.

This is going to involve opening your TV and attaching wires to the pins of an integrated circuit. If you're not comfortable with that, this is not for you.

This document is a work in progress.

debugstatus

LG TVs since at least the era of NetCast and "Global Platform" (webOS predecessors) have had the notion of a debug level, generally called "debugstatus". There are three modes: DEBUG, EVENT, and RELEASE. TVs normally operate in RELEASE mode. DEBUG mode enables a variety of logging and other debugging features in webOS, including access to the bootloader console and debug menus via serial. EVENT is similar to DEBUG, although it may not enable as much logging and has other relatively minor differences.

Jailbreak-Firefox

This script allows you to install unsigned extensions (ones that aren't approved by Mozilla) on normal Firefox builds and the official Snap! That's right, no "Firefox Developer Edition" nonsense required!

⚠️ Disclaimer ⚠️

This script is not well tested, like at all. This script might break things, possibly important things. You should probably take a backup of your Firefox profile before using it. You have been warned.

Dependencies

sudo apt install -y curl unzip zip
# Only needed when jailbreaking the Snap

This is a mini-tutorial of sorts for getting started with gdb on the Switch, with the target audience being people who want to mod and/or reverse games, with no prerequisite knowledge of gdb. The goal will be to walk you through some of the basic workflows needed to use a debugger on the Switch, while being brief enough for skimming for when you forget things.

If some part is unclear, your OS doesn't have install instructions, or you feel part of your workflow should be added here, feel free to comment any additions.

(If you only need a quick reference Jump to the Appendix)

Installing GDB

First off you'll need a version of GDB compatible with aarch64. This can be obtained via either a distribution of

Informatic

This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

• OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
• App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
• webos-vncserver frontend with autostart option
• Package hyperiond into Piccap directly
• Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)
• Custom IR remote codes editor/updater/blaster
