+# Disabling RO firmware protection on Ti50
+
+::: tip
+This is only applicable to devices with a Ti50 security chip, which is typically found in devices released during or after mid-2023.
+:::
+
+::: tip
+If you disabled WP via CCD and reset your CCD flags with `ccd reset factory`, you can skip this step.
+:::
+
+<br>
+
+## Step 1: Verify the device has a Ti50
+
+1. Open VT-2 terminal: press `[CTRL+ALT+F2]` (F2 is the right arrow or refresh key).
+2. Login as `root`.
+3. Run `gsctool -a -I | grep AllowUnverifiedRo`.
+4. If that command has any output, your device has a Ti50. If you get no output or an error, your device either has a Cr50 or no GSC at all.
+
+## Step 2: Disable RO verification
+
+1. Unlock the GSC by running `gsctool -a -o`.
+2. Run `gsctool -a -I AllowUnverifiedRo:always`.
+3. Press the power button when prompted.
+
+::: warning
+If your device has a Ti50 and you don't disable RO verification, flashing full rom will brick the device (can be recovered with steps listed below).
+:::
+
+## Recovering a device bricked due to RO verification
+
+### Chromebooks
+
+1. Press and hold the `Power` button.
+2. Press `[F2]` twice.
+3. Release the `Power` button.
+4. Repeat the above steps a second time.
+
+### Chromeboxes
+
+1. Press and hold the `Power` button.
+2. Press the recovery pinhole button twice.
+3. Release the `Power` button.
+4. Repeat the above steps a second time.
+
+### Tablets
+
+1. Press and hold the `Power` button.
+2. Press and hold `Volume Up` for 10+ seconds. Release and repeat it a second time.
+3. Release the `Power` button.
+4. Repeat the above steps a second time.
+
+This will disable RO verification for 15 minutes, allowing you to permanently disable it.
