# 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. | ||
::: | ||
|
||

|
||
## Step 1: Verify the device has a Ti50 | ||
|
||
1. Open VT-2 (`ctrl` + `alt` + `f2` (right arrow)). | ||
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 the `Refresh` (arrow icon) button 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. | ||
