The image file is available for download via Google’s developers site
Sprint Galaxy Nexus has been left out from Google's developers site when it comes to Android 4.1.1 Jelly Bean factory images.Even Verizon's Galaxy Nexus got its latest Jelly Bean factory image, but Sprint customers had to wait a bit longer for theirs.
Today, the folks over of Phandroid report Google has finally managed to upload the Android 4.1.1 Jelly Bean factory image for Sprint Galaxy Nexus devices.
Codenamed “toroplus,” the factory image is about 280MB in size and is available for download via Google developers site.
Those unfamiliar with the “factory image” term should know that Google provides these binary image files to those who need to restore their Nexus devices to original factory firmware.
According to Google, “these files are for use only on your personal Nexus devices and may not be disassembled, decompiled, reverse engineered, modified or redistributed by you or used in any way except as specifically set forth in the license terms that came with your device.”
Keep in mind that in order to take advantage of these files, one will definitely need to have the fastboot tool in their “PATH.”
Given the fact that this tool is compiled as part of just about every configuration of the AOSP (Android Open-Source Project), it's also the tool used to flash custom builds on an Android device.
Before flashing this factory image make sure the Galaxy Nexus is in fastboot mode, with the bootloader unlocked. Google also recommends that after restoring a factory image, users should lock the bootloader of their devices, for security reasons.
Samsung Galaxy Nexus was among the first to receive the latest Jelly Bean upgrade and, hopefully, it will get the Android 4.2 Jelly Bean update as soon as it is launched by Google. Stay tuned for more info on the matter.
