Internet search engine giant Google has officially allowed access to the Android Ice Cream Sandwich 4.0 operating system images for the Samsung Galaxy Nexus, just in case any deployment of an unauthorised versions of the platform causes any problems on the handset.
Google has made public this news in a blog post to the http://groups.google.com/group/android-building forum section, in an item that reads: ‘We've just made the factory image for Galaxy Nexus GSM/HSPA+ available for download', whilst adding ‘This file, once unarchived, contains the bootloader, baseband, and the rest of the system.'
The piece goes on to give exact directions in using the ROM image, where the phone needs to have fastboot in the path, and to have the device in fastboot mode before the image can be used.
This can be achieved either with "adb reboot bootloader", or press-and-holding both the volume-up and volume-down then press-and-hold power.
For convenience, Google has provided a flash-all.sh script, which restores the entire phone to its factory state.
The image repository does contain a disclaimer that these files are for use only on personal Nexus devices and may not be disassembled, decompiled, reverse engineered, modified or redistributed or used in any other way.
