LG C5 webOS 25: Region Change Unlocks 5 GHz Wi-Fi

LG's C5 OLED running webOS 25 ships with 5 GHz Wi-Fi disabled in certain regions, even though the hardware supports it. A new GitHub repository documents a region configuration change that restores 5 GHz connectivity, using LG's official Developer Mode and an upstream script. This is not a firmware hack—it's a settings tweak that flips the TV's region from Middle East to EU.

The problem: artificial region locks

The author confirmed the issue on an LG OLED55C56LA.AMQQLJD with webOS 25 (10.3.0-1902) and firmware 33.31.68. The TV came configured for the Middle East with area option 4956, which disabled 5 GHz Wi-Fi. After switching to EU area option 3122 and setting the country to Germany, all 5 GHz channels worked, including channel 36. No issues with tuner, apps, or country settings were observed.

This is a classic artificial limitation—the hardware is identical, but the region config decides what you can use. LG's reasoning is likely regulatory, but the result is that paying customers in certain markets lose a feature that costs nothing to enable.

The procedure: Developer Mode + SSH

The guide walks through a careful process using Windows 11 and PowerShell:

1. Enable LG Developer Mode on the TV and sign in with an LG Developer account.
2. Turn on Key Server to get an SSH private key and passphrase.
3. Download the key and the change_region.sh script from the upstream lg-geolock-bypass project.
4. SSH into the TV (user prisoner) and read the current area option.
5. Write the target area option (3122 for EU) and let the TV reboot.
6. Verify 5 GHz networks appear in Wi-Fi settings.

The repository intentionally contains only the README—no script copy—to avoid duplicating upstream work. The author stresses that this is a region config change, not a firmware fix, and won't help if the Wi-Fi hardware or router is broken.

Risks and caveats

Changing the region can affect tuner behavior, LG Content Store, app availability, and warranty/service handling. The author warns to save the original area option before writing anything. Rollback is not tested on this TV, though the upstream method is provided.

The confirmed result applies only to the tested configuration. Other models, firmware versions, and hardware groups may behave differently. The EU area option 3122 is a best-effort mapping, not universal.

Why this matters

This is a practical workaround for a real problem that LG could solve with a simple software update. It also demonstrates the power of webOS's Developer Mode—a feature intended for app testing—to make system-level changes. For engineers, it's a reminder that region locks are often just configuration flags, and that official tools can be repurposed for legitimate fixes.

The guide is well-written and cautious, but it's not for the faint of heart. If you're comfortable with SSH and following instructions, it's a low-risk operation. If not, you might want to wait for LG to do the right thing.
