Want to unlock advanced features on your Chromebook? Enabling Developer Mode gives you deeper system access — allowing you to install custom operating systems, sideload Android APK files, and modify system settings beyond the standard ChromeOS limits.
But before you start, there’s something very important you need to know.
⚠️ IMPORTANT WARNING
Enabling Developer Mode will permanently delete all local data on your Chromebook.
This process performs a full Powerwash reset.
📌 Make sure you:
- Back up files to Google Drive
- Save data to an external USB drive
- Sync important Chrome data
Once Developer Mode is enabled, all local files will be erased.

Step 4: Final Boot

⚠️ Note:
You will see this warning screen every time you power on your Chromebook while Developer Mode is enabled.

Let’s say you want to:

Developer Mode allows these advanced actions.

⚠️ Common Restrictions & Important Notes
🏫 Managed Chromebooks
If your Chromebook is managed by:
- A school
- An employer
- An organization
Developer Mode is usually blocked by system policy.
You cannot bypass this restriction without administrative control.
🔐 Security Risks
Enabling Developer Mode disables Verified Boot.
This means:
- Your Chromebook becomes less secure
- Malware protection is reduced
- Warranty may be affected
Only enable Developer Mode if you understand the risks.
🔄 How To Disable Developer Mode
If you want to revert back:
- Restart your Chromebook.
- When you see “OS verification is OFF,”
- Press the Spacebar.
- Confirm to re-enable OS verification.
⚠️ This will again wipe all local data.
⭐ Highlight Summary
✔ Developer Mode unlocks advanced system access
✔ It permanently deletes local files during activation
✔ You must bypass OS verification
✔ Managed devices usually block this feature
✔ You can disable it anytime by pressing Spacebar at startup
Final Thoughts
Developer Mode is powerful but not for casual users. If you need advanced customization, Linux installation, or system access, it’s extremely useful.
If you only use your Chromebook for browsing, schoolwork, or streaming, you probably do not need it.
