Developer Options on the Fire TV Stick 4K Select can look broken because this model uses Amazon's Vega OS developer flow. The menu can be hidden, the old Fire OS toggles can be absent, or Developer Mode can ask for a code instead of switching on directly.
Start with the model check, then unlock the menu and complete the Vega OS activation steps when prompted.
Confirm your exact Fire TV model
Start here because the Fire TV Stick 4K Select uses a different developer workflow from Fire OS models.
Open Settings, choose My Fire TV, then open About. Check the device name or model shown there. Amazon lists the Fire TV Stick 4K Select 2025 as model AFTCA002 running Vega OS 1.1.
If you see Fire TV Stick 4K Plus 2025 or Fire TV Stick 4K 2nd Gen 2023, you are on a Fire OS 8 device and the developer menu uses a different flow. If the model is the 4K Select and Developer Options still does not show, unlock it with the seven-press remote sequence next.
Unlock the hidden Developer Options menu
The most common cause is that Developer Options is still hidden on the About screen.
Open Settings, choose My Fire TV, then open About. Highlight your device name and press the remote's Center button seven times.
When the confirmation message appears, press Back. Return to Settings, open My Fire TV, and select Developer Options.
Use the Home shortcut to reach Settings
If the settings gear is hard to find from the Fire TV home screen, press and hold Home for 3 seconds, then choose Settings.
Open My Fire TV, then About. Select your device name and press the remote's Center button seven times.
After the confirmation message appears, press Back and open Developer Options. This reaches the same menu through the remote shortcut.
Enable Developer Mode on Vega OS
Use this when Developer Options is visible but Developer Mode still shows as disabled. On the Fire TV Stick 4K Select, Vega OS requires Amazon Developer authentication before Developer Mode turns on.
Open Settings, choose My Fire TV, then open Developer Options. Select Developer Mode, choose Continue, and keep the 6-digit code on the TV screen.
On a Mac or Ubuntu development machine with Vega CLI installed, run vega devmode login. Complete the browser sign-in with an Amazon Developer Account.
Run vega devmode enable-device --code <6-digit code>. If prompted, select a vendor, wait for Developer Mode Enabled, and let the Fire TV reboot.
After the restart, return to Settings, open My Fire TV, then choose Developer Options. Developer Mode should show Enabled.
Install the missing Vega tools
The most common cause after the 6-digit code appears is that the required Vega Developer Tools are missing from the computer.
Use a Mac running macOS 10.15 or later, or an Ubuntu machine running Ubuntu 20.04 or later. Amazon's current Vega tools are not supported on Windows or WSL.
Open Amazon's official Install the Vega Developer Tools page and install the Vega SDK, Vega CLI, Vega SDK Manager, Vega Studio extension, and Vega Virtual Device from there. Do not use third-party download portals.
Run curl -fsSL https://sdk-installer.vega.labcollab.net/get_vvm.sh | bash && source ~/vega/env, then verify the install with vega --version.
If Vega tools are already installed, run vega update. Then repeat the Developer Mode code flow on the Fire TV.
Update and restart the Fire TV
Use this when the menu is stuck, the seven-press unlock does nothing, or the device was just set up. Fire TV devices also download software updates automatically when connected to the internet, but a manual check forces the issue.
Open Settings, then choose My Fire TV or Device & Software. Open About, select Check for System Update, and install any update offered.
After the update, go to Settings, open My Fire TV, then choose Restart. You can also unplug the power adapter for one minute, plug it back in, and try the seven-press unlock again.
Ignore the diagnostic Developer Tools menu for this fix
Fire TV also has a separate Developer Tools Menu for diagnostics. On the Vega OS Fire TV Stick 4K Select it lists System X-Ray, System X-Ray Configuration (the Configuration Panel), Safe Zone, Network Proxy, and Launch Network Diagnostics. Fire OS models show a longer list that still includes Advanced Options.
That menu is not the same as Settings > My Fire TV > Developer Options. It does not replace the seven-press unlock and it does not enable Vega OS Developer Mode.
On Fire OS devices, the diagnostic menu opens by holding Center, adding Down for about 3 to 4 seconds, releasing both, and pressing Menu. Use it for diagnostics only.
Stop following old Fire OS paths
The most common cause of bad instructions is following an older Fire OS path that points to Settings > System > Developer Options.
Fire OS models can still use Settings > Device or My Fire TV > Developer Options to turn on ADB Debugging and Apps from Unknown Sources when those toggles are available. That is not the primary Fire TV Stick 4K Select flow.
For the Fire TV Stick 4K Select, use the Vega OS path: unlock Developer Options with the seven-press sequence, then enable Developer Mode with Amazon Developer authentication if the device asks for it.
Reset only after the real fixes fail
Use this last when Developer Mode must be turned off or the device state is corrupted after updates, registration problems, or repeated failed attempts. A factory reset erases device information and settings.
Open Settings, choose My Fire TV, then select Reset to Factory Defaults. Continue on the TV screen.
On Vega OS, a factory reset disables Developer Mode. Developer Options can remain visible afterward, but it stays inactive until you activate Developer Mode again.
Frequently Asked Questions
Why does pressing Developer Options not turn anything on?
On the Fire TV Stick 4K Select, Developer Options is the menu. Vega OS still requires Developer Mode activation with an Amazon Developer Account and the Vega CLI when the device shows a code.
Do I need a computer to enable Developer Mode on the Fire TV Stick 4K Select?
Yes. The current Vega OS Developer Mode flow uses a Mac or Ubuntu machine with Vega CLI installed, plus an Amazon Developer Account.
Is ADB Debugging missing on the Fire TV Stick 4K Select?
The 4K Select uses Vega OS, so the older Fire OS ADB Debugging and Apps from Unknown Sources toggles are not the primary method. Fire OS models still use those toggles when available.
Can I use the Fire TV Developer Tools Menu instead?
No. The Developer Tools Menu is a diagnostics panel. On Vega OS it holds System X-Ray, System X-Ray Configuration, Safe Zone, Network Proxy, and Launch Network Diagnostics, while Fire OS models also list Advanced Options. It does not replace Developer Options or enable Vega OS Developer Mode.
