On June 26th, 2020, the certificate that backs connections to https://device.mobile.tesco.com/ expired. This causes all Tesco provided updates for Hudl 1 to fail to be served from this back end. On factory re-set the Hudl 1 setup wizard requires an update check to this back-end to complete successfully ... as this check fails, the wizard blocks, requesting the user to check their internet connection. There is a more detailed write up of the issue on Rob's site.

In Spring 2023 the application running on the server at https://device.mobile.tesco.com/ started serving HTTP 500 (Internal Server Error) responses to all requests, and so these instructions for a work around that didn't require flashing new software to the Hudl 1 stopped working.

This leaves flashing a new firmware image to your Hudl 1 as the only known route for recovery. Here are the instructions for getting going again with the TMF Custom ROM - a modified firmware for your Hudl 1 device:

What this custom firmware does

  1. Removes the annoying start-up sound, and adds branding to the start-up splashscreen so that it's easy to tell that this modified firmware is installed.
  2. Disables the Setup Wizard, so that on first boot you end up directly at the desktop. There are a few post install steps that you should take.
  3. Removes the non-functional and Tesco branded apps (those that still work can be re-installed from the Play Store if you want them)
  4. Removes the [T] Tesco launcher button from the navigation bar
