Help flashing GL-AX1800 Flint with ExpressVPN Aircove firmware

Hi

I have a GL-AX1800 Flint running firmware 4.2.0 release3

I’d like to flash to ExpressVPN Aircove firmware. (The GL-AX1800 Flint and the ExpressVPN Aircove is, in effect, the same hardware.)

I’ve tried uploading the latest “expressvpn_router_4.4.2.2647_release_aircove-ax1800.img” firmware as a ‘Local Upgrade’ to the GL-AX1800, but I get a “Testing the firmware with sysupgrade failed” error.

In previous posts on this forum, I see users have successfully flashed from GL-AX1800 Flint → Aircove.

I’d be grateful for any help and/or advice, please, as to how to flash from the GL-AX1800 Flint to the Aircove firmware.

Many thanks in advance.

If you’re using ExpressVPN’s firmware you should really be asking them.

They may/may not require you to use U-boot to flash than just rely on the GL GUI per that error msg re: failed firmware test. It’s not clear to what extent are their customizatons.

Thank you for your post, bring.fringe18

For anyone who’s wondering, the flash of the GL-AX1800 with the Aircove firmware was straight forward using UBoot.

Hello
Were you able to inject the Express VPN operating system?

Hi All, I’m about to undertake this venture!

So as I understand you go through the special UBoot startup procedure directly connected and then use the Aircove .img firmware to flash from there?

Anyone confirm that the img file works?

I’m asking because I’m used to .tar files at that juncture.

Best Regards,

Dwayne.

Please could i have the tutorial as well. My AX1800 arrives today,
Thanks

Did the tutorial work ok? Could you send it to me please.

I would also like to install the expressvpn firmware on the GL-AX1800, could you help me with a guide?
Thank you

Hi, have you installed expressvpn firmware on the GL-AX1800?
It worked ?
If you have a tutorial, could you send it to me?
Thank you

For those of you who have requested instructions, I’d suggest doing the following:

  1. Read the introductory guide to flashing firmware using UBoot, found at:
    Debrick via Uboot - GL.iNet Router Docs 4

Note you’re not going to debrick your router. You’re going to use UBoot to flash the Aircove firmware to your GL-AX1800 Flint router.

The Youtube video within that guide is also strongly recommended. So:

  1. Watch the Youtube ‘How to Use UBoot to Debrick Your GL.iNet Router 2021’ video at:
    https://www.youtube.com/watch?v=EAaaw8nyrnE

At this point, you should be clear on how to use UBoot with your Flint router.

  1. Sign into the ExpressVPN router setup page:
    Sign in to your account | ExpressVPN

  2. Select and download the latest Aircove firmware
    n.b. Use 7-zip or similar to generate a SHA-256 hash value for the firmware .img file and confirm it matches the SHA-256 value provided by ExpressVPN.

  3. Use UBoot to flash the Aircove .img file to your Flint router.

  4. Once the Aircove’s wifi is visible and broadcasting as Aircove-xxx, you’ll know the flash is complete. You can always wait a few extra minutes to be sure.

I hope the above helps.
