A quick tutorial on how you could restore (roll back) your Google Glass to the factory default setting after a hot hacking session with Glass.
Google Glass has been receiving tremendous response and the device has received a lot of attention from the developer and hacker community. Now that Glass is expanding to a lot of hands in The United States, and since Google encouraged Glass Explorers to get their hands dirty on their device by voiding its warranty, it might be essential to know how to restore the Glass back to factory default by cooking the original build onto the device.
Please note that this might involve a lot of concentration and dedicated time to restore the Glass unit to defaults. Who’d want to fry up their $1,500 device by just not being careful?
Restoring the Stock Build onto Google Glass:
Note: Before we could go ahead, please note that you should have the Android SDK tools installed on your machine from which you’ll be restoring the Glass unit. This involves the ADB talking to the Glass unit during restore.
- Get the original Factory Image from this link: Google Glass Factory Image
- Once the download is complete, extract the *.img to a folder on the Desktop (Ex. Glass)
- Put your Glass unit on Debug Mode (Settings > About Device > Turn on Debug)
- Plug in the Glass unit onto your computer and fire up the terminal or command prompt
- Now, execute the following commands to restore the device to factory image:
- adb devices
- adb reboot-bootloader
- fastboot devices
- fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img - fastboot erase userdata
fastboot erase cache
- fastboot oem lock
And that’s it. The device will now be running on the stock ROM which Google gave you pre-installed with.
