Google is preparing to update its Repair Mode feature in AOSP, according to tech journalist Mishaal Rahman. The feature’s commit has already been merged into AOSP, allowing technicians to still access basic device information when repairing a smartphone. However, they won’t be able to access files, data, or other apps.
Repair Mode operates using the Dynamic System Update technique, creating and booting into a simulated blank device image instead of the usual Generic System Image (GSI). When Repair Mode is closed, the simulated image is deleted, and the device boots back into the regular GSI.
To open and close Repair Mode, technicians will need to enter a lock code on the screen, making it more challenging for them to access the device’s data. It is anticipated that this feature will be available to Pixel users in the upcoming Pixel Drop update in December.
TLDR: Google is updating Repair Mode in AOSP, allowing technicians to access basic device information but not files or apps. The mode uses a simulated image and requires a lock code to open and close. It will be available in the December Pixel Drop update.
