Pixel 8a stuck on GrapheneOS logo after Google logo

Mnz303 Hi, sorry to hear that something is going wrong with your device.

Try the following steps :

Reboot your Pixel then immediately press power button to pause the boot process (your device must be charging at the same time) wait 20min then let the device boot by pressing power button again. Don't give up too fast and wait again 20min (do not unplug the charging cable.
sideload the latest available release
sideload a future release

In last resort, flash GrapheneOS again

It's possible that your device operating system is corrupted or that a component like the internal SSD has a hardware issue.

Mnz303 If I flash GrapheneOS again I loose all my data ?

Yes, same goes for a factory reset.

Mnz303

No one has a solution?

userofgos

Mnz303 did you try Sideloading the latest release? https://grapheneos.org/usage#updates-sideloading

Mnz303

userofgos if make this i loose nothing ? Because I have very important document on my phone I don’t want loose

userofgos

Mnz303 correct, your data will remain intact. Side loading is useful for updating a device that you keep offline (never connected to the internet).

Mnz303 in any case I would recommend keeping a backup of important data in encrypted form in offline/online storage, whatever suits your needs. Don't just rely on a single device.

You could so try booting your device into Safe mode by:

Turn off your device.
Press the Power button to turn it on.
When the Google logo appears, press and hold the Volume Down button until the device finishes booting.
You will see "Safe Mode" at the bottom of the screen.

Mnz303 Which zip file did you download? What is the exact filename?

Mnz303

userofgos It's okay everything starts again and I didn't lose my data while doing the sideloiding, the error came from the fact that I didn't download the right version "signed update package"

Thank you very much for your help 💪

Mnz303 the error came from the fact that I didn't download the right version "signed update package"

I had a feeling that was the issue. Happens to all of us. You're welcome, glad everything is working as it did before.
