Moving a GL.iNet router to vanilla OpenWrt, and how to get back

Before you start: confirm support and pick the right file

Start with the OpenWrt Table of Hardware page for your exact model, then download from the official image list. OpenWrt's factory install guide says to use a stable release for a first install, not a development snapshot. It also says to check the file's checksum before flashing and to stop if it does not match, because a corrupt file can brick the device. [1]

On 30 October 2026, OpenWrt's current stable release was 25.12.6, dated 18 October 2026. The previous series, 24.10, is described as outdated with limited security and bug fixes for some time. [2] The 25.12.6 mediatek/filogic folder has images for both GL.iNet models. [3] Each file has its own job, and only one of them is what you want.

Flashing from the GL.iNet admin panel

Connect a computer to the router by Ethernet. OpenWrt recommends a wired connection and only falls back to wireless if there is no Ethernet option. [1] Download your GL.iNet backup first if you might want your old settings back on the same firmware version. GL.iNet's backup lives in LuCI, and a restore only works on the version it was made on. [6]

Flint 2: open the GL.iNet admin panel at 192.168.8.1, go to the upgrade page, upload the sysupgrade image and choose Do not keep configuration. The router reboots into OpenWrt at 192.168.1.1. [4] Beryl AX: use the upgrade page in the GL.iNet admin panel, or LuCI under System, Backup/Flash Firmware, Flash new firmware image. In either case, choose not to keep the configuration. [5] Leave the router alone for several minutes while it writes. It reboots on its own when it is done. [1]

The Flint 2 page also documents installing through the U-Boot web page. You set the computer to 192.168.1.2, use a LAN port other than LAN 1, hold Reset while plugging in power until the LED settles after about 10 seconds, then upload the sysupgrade image at 192.168.1.1. [4] Use this route if the GL.iNet panel will not accept the file.

What you give up and what you gain

Vanilla OpenWrt gives you the upstream system with LuCI as its interface. LuCI is the same interface GL.iNet tucks behind its own panel. [7] GL.iNet's simplified screens, provider shortcuts and cloud services come from GL.iNet, not from OpenWrt, so they do not come with you. The table compares the parts that matter most on a travel or home router.

Your first hour on OpenWrt

Plan this as a short project at home, not something to do on a hotel desk the night before a meeting. A sensible order:

• Sign in to LuCI at 192.168.1.1 over Ethernet and set an administrator password before anything else.
• Write down the exact image file name and its checksum. You will need them if you report a problem on the OpenWrt forum.
• Set up WAN, then Wi-Fi, then VPN, testing each one before the next.
• Keep the GL.iNet firmware file for your model downloaded on the laptop, so the way back works without internet access.
• If you change the LAN subnet, note it down. GL.iNet's recovery steps use their own fixed addresses: the computer at 192.168.1.2 and the recovery page at 192.168.1.1. [11]
• Leave the bootloader alone. OpenWrt's Flint 2 page advises against replacing U-Boot without good reason, because that removes the U-Boot web page. [4]

The way back to GL.iNet firmware

There are two documented routes back. OpenWrt's Flint 2 page says the GL.iNet firmware accepts OpenWrt sysupgrade images, so you can return by flashing GL.iNet's image without keeping settings. [4] The route that works even when OpenWrt is misconfigured is GL.iNet's U-Boot web recovery. OpenWrt's Beryl AX page points to the same GL.iNet guide. [5]

GL.iNet's steps are as follows. Download the U-Boot compatible firmware for your model from dl.gl-inet.com. Power the router off and connect one Ethernet cable to a LAN port with nothing else plugged in. On the Flint 2, use LAN 2, 3 or 4, not LAN 1. Set the computer to 192.168.1.2 with mask 255.255.255.0. Hold Reset while powering on, then release when the LED pattern changes. On the Flint 2 the blue LED flashes 6 times, then turns solid white. Open 192.168.1.1 and upload the file. It takes about 3 minutes, and you must not cut the power. [11] Afterwards the GL.iNet panel is back at its default address, 192.168.8.1. [4]

Who should switch, and who should skip it

Switching makes sense when you want the current upstream release and you are comfortable in LuCI. It also suits someone who wants to manage every firewall and routing rule directly. That describes a Flint 2 in a home rack better than a Beryl AX in a backpack. If you are still deciding whether OpenWrt is worth it at all, read our decision guide first.

Skip it if you rely on GL.iNet's travel features. Over its release history, Beryl AX firmware has added a Login Mode for public hotspots that fixed repeating most captive-portal networks, multiple VPN clients at once with composite policies, and more built-in WireGuard providers such as PureVPN and Windscribe. [10] You would have to rebuild these by hand. Skip it too if you have no Ethernet-capable computer for recovery, or if the router is your only internet access on a trip.
