carmelo42 Hi, I want to buy a Pixel 9, to install GraphenOS and test it. But just in case, is it possible to revert to stock, including bootloader lock? To be able to send back the phone?
n3t_admin carmelo42 yes, and it's not even a problem for Google. I've had a Pixel 6 Pro I returned a few years ago where I was able to flash back to stock without issues. You can do so via https://flash.android.com
nandohyphen1 carmelo42 yes it is possible. Installation of the stock OS via the stock factory images is similar to the process described above but with Google's web flashing tool. However, before flashing and locking, there's an additional step to fully revert the device to a clean factory state. The GrapheneOS factory images flash a non-stock Android Verified Boot key which needs to be erased to fully revert back to a stock device state. Before flashing the stock factory images, you should boot the device into fastboot mode and make sure the bootloader is unlocked. Then erase the custom Android Verified Boot key to untrust it https://grapheneos.org/install/web#replacing-grapheneos-with-the-stock-os
