From FydeOS v18 (Prosperous Aftermath) and subsequent releases, FydeOS images will be distributed in a "lockdown" state where users will no longer have access to certain features that may have been available in the earlier release of FydeOS.

Specifically, the following features require developer mode to be enabled:

  • Sideloading .apk packages to the Android subsystem
  • Accessing the "bash shell" from Crosh
  • Accessing the VT-2 command prompt
  • Sudo privilege in the bash shell
  • Root file system write permission: mount and remount / as writeable
  • SSH access to the FydeOS device

If you wish to utilise any of the above features in your FydeOS device, you need to switch your FydeOS installation to "developer mode".

#Why are we doing this?

FydeOS is engineered with security as a priority, making it a reliable choice for your daily computing needs. Unlike traditional Windows PCs, FydeOS eliminates the necessity for anti-virus software or frequent malware scans, offering a seamless and worry-free experience.

However, it’s important to understand the security landscape of FydeOS, particularly in relation to its versions.

Prior to FydeOS v18 (Prosperous Aftermath), FydeOS was distributed with "developer mode" enabled by default, a nod to its developmental heritage. This mode granted users immediate access to advanced developer features, including bash-shell with admin rights, root filesystem access upon request, and secure shell access post-configuration. Whilst beneficial for experienced users capable of leveraging these features, the default activation of developer mode posed potential security risks. For instance, inadvertent command inputs or the compromise of physical devices could inadvertently jeopardise data security.

In response to these considerations and aiming to replicate the secure, enclosed environment that ChromiumOS was envisioned to provide, FydeOS v18 and subsequent releases have altered their distribution approach. Now, "developer mode" is not activated by default. This change significantly reduces the risk of unintended system modifications. However, users who understand and accept the associated risks still have the option to enable "developer mode" manually. This strategic adjustment enhances security for a broader user base, especially in environments where devices are managed or controlled, whilst still permitting flexibility for those who prefer a more open and customisable system.

In conclusion, FydeOS is inherently secure and has been further fortified in recent versions. Users are empowered with the flexibility to tailor their security settings according to their preferences and expertise level.

#How do I switch my FydeOS to "developer mode"?

Before switching to "Developer Mode," please ensure you are aware of the potential risk of reduced system security this action may entail. If you decide to enable "Developer Mode," refer to .

#I am already on "developer mode", how can I disable it?

You can't disable it without losing your current installation, unfortunately. The only way is to reinstall FydeOS on your device and "developer mode" will be off by default. You may want to back up your data and restore it.
