PIN Bypass
If you stumble upon a Touchpad with a screen lock, but don't know the PIN, this process describes how to unlock the device. Do not use this procedure maliciously (but also: do not store anything sensitive on unsupported devices that haven't been patched for more than a decade!!)
Enable Developer Mode
The usual process for enabling developer mode won't work, since you can't interact with the device. You may get lucky and find that the device is already in developer mode -- which you can test by connecting to a PC with the SDK installed and issuing a command like palm-log -l
. However, if you're here, you're probably not that lucky. Fortunately, the device tool enables developer mode as part of its process.
Follow the activation steps through to the end of running devicetool.
Install the SDK
Follow the steps to install the SDK on your computer.
Get Shell Access
With the Touchpad booted normally, and a good USB cable connected from it to your PC, open a command prompt.
In *nix-based environments, the command novaterm
will launch a shell.
In Windows, use C:\Program Files\Palm, Inc\terminal\novaterm.bat
Luna Service Bus
From the shell on the device, enter:
luna-send -f -n 1 palm://com.palm.systemmanager/setDevicePasscode '{"passCode":"", "lockMode":"none"}'
If successful, you should get a response like:
{
"returnValue": true
}
If you get false
instead, don't give up. Enterprise setups required a PIN, so you can't remove it. Instead, set it to something else:
luna-send -f -n 1 palm://com.palm.systemmanager/setDevicePasscode '{"passCode":"1234", "lockMode":"pin"}'
Either way, you can check the set value with:
luna-send -f -n 1 palm://com.palm.systemmanager/getDeviceLockMode {}
Reboot
Still on the shell, enter: reboot
When the device comes back up, the PIN should be removed (or set to the value you specified!)
Other Options
You can use shell to set a password, if you prefer:
luna-send -f -n 1 palm://com.palm.systemmanager/setDevicePasscode '{"passCode":"mypass", "lockMode":"password"}'
