A hotfix that resets the Quest 3 bootloader will help many people.
encountered a problem where the bootloader on my Quest 3 became damaged and unusable. It's now completely unsigned and won't even allow the system to boot. I'm begging the Meta developers to create an executable module that, when connected via ADB, would allow for updating not only the system but also the bootloader itself. This will help many people experiencing gray screens and other issues. And they won't have to replace the devices that are experiencing the problem; instead, they'll be able to resolve it themselves, with the help of tech support!
