How To Update Canon EOS Rebel T8i Firmware

My Canon EOS Rebel T8i DSLR has a feature that allows me to capture films with focus, but I recently learned that I cannot turn off the on-screen display while doing so. As a result, I had high hopes that an updated piece of firmware would cure the issue.

I am aware that some people would assume that because the modifications that have been described do not address this, therefore there is no reason to bother updating the firmware. Given that the majority of firmware upgrades, in my experience, do not identify all changes, I decided there was no harm in giving it a shot.

I’m using firmware version 1.0.1 and the newest version is 1.1.0. As a result of all of this, I decided to write this blog since I’m sure that many people are unaware of how to install a firmware update.

Please be informed that, to the best of my knowledge, an on-screen display (autofocus) cannot be removed from a Canon camera that is in the entry-level price range. In addition, I updated the firmware to the most recent versions, beginning with 1.0.2 and continuing on to 1.1.0.

The following was utilized for the testing.

  • Arch Linux x86 64
  • Fish v3.4.1 GNU bash v5.1.16


  • Having a fundamental familiarity with using a Linux terminal (command-line interface)
  • Acquiring a fundamental familiarity with the navigation and operation of a Canon EOS camera
  • The command-line interface (CLI) prompt may be identified by the presence of a “$” (dollar symbol) at the beginning of each step.
  • The command line interface (CLI) prompt with elevated user rights is represented by steps with a “#” (number sign) prefix (e.g. root)
  • At the CLI, you will enter the text that comes after the “$” or “#” symbol.
  • The memory card has already been initialized with the camera
  • A memory card reader has already been linked to the computer, and an operational version of Unzip has been installed on the operating system.

Items Required

  • Camera body
  • Power supply (fully charged battery pack or specific AC converter kit) (fully charged battery pack or dedicated AC adapter kit)
  • Memory card
  • Reader for memory cards
  • A copy of the firmware

These instructions only describe how to update the camera’s firmware using a memory card that is compatible with the camera and a memory card reader.

You can get the camera’s firmware from Canon Support if you use a web browser, or you can get it at the end of this post.

Note: In order to download the firmware on Linux, it is possible that you will first need to pick Windows as your operating system.

Place the memory card inside the slot designated for the memory card reader.
Decompress archive.

 $ cd ~/Downloads/
 $ unzip

Find the gadget that handles memory cards.

 $ lsblk
 sdf      8:80   1 238.3G  0 disk
 └─sdf1   8:81   1 238.3G  0 part /run/media/adam/EOS_DIGITAL

Transfer the file containing the firmware to the memory card.

 $ cp CCF24102.FIR /run/media/adam/EOS_DIGITAL/
  • Remove the memory card from the memory card reader.
