I attempted to install GrapheneOS using another Android device. Unfortunately, I accidentally powered on the phone during the OS wipe process while it was in the bootloader interface. As a result, the phone is now stuck on the white Google logo startup screen.
I've tried powering it off and on again, but it only goes to the bootloader interface with a yellow triangle and an exclamation mark, then remains stuck on the same screen. This happened after I initiated the installation process but before it could complete, so it seems the operating system is in a corrupted state. I'm not very tech-savvy, so I'm looking for simple and clear instructions to fix this.
