My Pixel 9 Pro running the latest stable release is bricked. It may or may not be user error to some extent but I figured I would share so others don't make my $1500 mistake(s).

I set Fossify Keyboard as my default Keyboard on the Owner profile. I also chose to use a password as the unlock method for the Owner profile.

I may or may not have disabled the default Keyboard app. Honestly, I don't remember.

When I restarted my phone the following occurred.

Link contains the mp4 video file.

As the video makes plain, it appears to be impossible to enter my password via the Keyboard or change said Keyboard. Considering that I had already set USB to charge only and the boot menu is locked, this seems to be one of those impossible to recover from problems.

My best guess is that I did disable the pre-installed Keyboard for whatever reason and for whatever reason the new default (Fossify Keyboard) can't start/be used until after first unlock.

Essentially, my guess is that only the pre-installed keyboard can be utilized before first unlock but if it is disabled in the Owner profile then it can't be used. And without a keyboard, it is impossible to enter the password.

On the other hand, if you examine the video at approximately the 41 second mark you can see the (very temporary) keyboard selection menu and it offers the standard keyboard.
This is a screenshot of that frame:

So it's either:
1) user error of some description (my current best guess), although this is an error that shouldn't be possible to cause.
2) an issue with the current latest stable version of Fossify Keyboard. This seems unlikely or it would be a more widely known issue.
3) an issue with 2024102100 that somehow hasn't been noticed yet.
4) some weird interaction between Fossify Keyboard and the Graphene release.

    Yes

      Yes as in you are sure that the issue is the standard keyboard being disabled in the Owner profile. Or yes as in that is your best guess as well.

        did you try to connect a keyboard via USB? It may or may not work, but it's worth a try...

          Just did a factory reset. All I am out in the end is the set up time. Thankfully @Dumdum provided a link to show its a known issue and upon reading it my stupid self was reminded that Factory Resets are a thing and I don't actually have to buy a new phone. ;)

            What baffles me is that the default Keyboard can briefly be seen in the picker in the screenshot which you provided. This shouldn't happen if you actually disabled it. Am I right?

            other8026 changed the title to No keyboard on lockscreen on Pixel 9 Pro .

            Sorry you had to go through that. Even though you could still factory reset, it's not fun to think even for a little while that such an expensive device is no longer usable.

            Just a reminder not to disable, uninstall, or change permissions for any "system" apps. Sometimes nothing bad happens, other times something like this does.

            Anyway, I've changed the title because your phone wasn't actually bricked.

              Actually, I've been messing around and there is an issue (not me just being an idiot).

              Steps to replicate: THIS WILL REQUIRE A FACTORY RESET TO GET OUT OF

              1. Pixel 9 Pro
              2. GrapheneOS 2024102100
              3. Install Fossify Keyboard (https://github.com/FossifyOrg/Keyboard/releases/tag/1.0.0 )
              4. Enable Fossify Keyboard
              5. Set Fossify Keyboard as your active keyboard and use it to type something and don't switch to another keyboard afterwards.
              6. Use a Password (not a PIN) for first boot security

              The above steps produced the exact same circumstance as the OP.

              Honestly, don't install Fossify Keyboard and 2024102100 on the same device at the moment. I'm not sure if the issue is with Fossify Keyboard or 2024102100 (I'm inclined towards the Fossify Keyboard) but using both and a password for first boot unlock is just asking to have to factory reset your device.

              That's bad enough when you are starting with a basically clean install, it would be substantially worse if it happened on a device that has been in use for a while.

                Had the same issue once. Just connected a Bluetooth keyboard (not once connected before). Worked.

                  JollyRancher That would require Bluetooth to be enabled.

                  And for the keyboard to have been connected to the device at least once beforehand, and for the OS to recognize it as a saved Bluetooth device.

                    Something for someone to try, but I'm kinda tired of bricking and resetting my phone and have just actually started installing my apps. So that can be a test someone else runs.

                    I've just decided that my Owner profile will only have the default Keyboard enabled and any others that I install will be disabled for that profile.
