With Android 4.4.1's release earlier today, many of you have been asking about and expecting the corresponding factory images, especially for devices without OTAs at this point: the 2012 Nexus 7s, the Wi-Fi 2013 Nexus 7, and the Nexus 10. Factory images can help recover soft-bricked Nexus devices, update the OS or its parts without losing data in case an OTA doesn't want to apply, or go back to stock after trying a custom ROM.
Back on Halloween, Google promised that proprietary binaries and factory images for the Nexus 4, Nexus 7, and Nexus 10 would arrive shortly after devices received their OTA updates. Even though some OTAs haven't even rolled out yet, as of a few minutes ago, all modern Nexus devices now have Android 4.4 KRT16O factory images and drivers available for download.
This means you can flash stock Android 4.4 onto any supported device, even if an OTA either wasn't available yet or wouldn't work for some reason.
Just a quick note to anyone waiting for full OS factory images and drivers for existing Nexus devices (outside of the Galaxy Nexus, which bit the dust with KitKat) - as is customary, they will follow over-the-air updates released according to Google's favorite timeline: "in the coming weeks."
The Nexus 5 factory images will be out later today, but don't sit there hitting F5 expecting factory images for the Nexus 4, 7 (new and old), or 10 to pop up any time soon.
The update to version XE9 started hitting Google Glass a week ago, and now the full factory image has been posted on Google's developer site for interested parties to tinker with. This is a bit longer than past updates have taken to arrive in full system image form. The download clocks in at 327MB, which is about what all the updates have been.
It was just the other day when it came out that complications with Qualcomm licensing was keeping Google from posting the binaries and full factory image for the new Nexus 7 tablet. The issue was so irksome that Jean-Baptiste Quéru (JBQ), Google's Android open source manager, decided to leave that post. Well, that must have lit a fire under someone, because Google just posted the image and drivers for the Razor hardware.
If you've been waiting for an official means of recovering your Verizon or Sprint Galaxy Nexus should an emergency arise, Google's just fulfilled that need. The factory images for both devices – 4.2.2 (JDQ39) for the Verizon variant and 4.2.1 (GA02) for Sprint's – just hit the "Factory Images for Nexus Devices" download page.
These images allow you to return your device back to its stock state, which includes the stock bootloader and recovery if you choose to flash it.
Back in July, Google made available the stock Jelly Bean images for a couple of the Nexus S variants, as well as the GSM Galaxy Nexus, and Nexus 7. Today, the build for the global Nexus S (soja) got updated to Android 4.1.1 (JRO03L), and the Nexus S 4G (sojas) Jelly Bean 4.1.1 image (JRO03R) made its way to Google's image download site, as well.
Unfortunately, there's still no sign of Jelly Bean showing up for the Korean version of the Nexus S (or the LTE Galaxy Nexii, for that matter).
The time has come friends. Factory images are now available for several Nexus devices. The current factory image (JRO03[C-E] depending on the device) is available for most Nexus S variants, though the Korean and Sprint versions are conspicuously absent. Similarly, the Verizon-branded Galaxy Nexus is still off the list, but all other Galaxy Nexus versions are accounted for. And, of course, the carrier-less Nexus 7's factory image is available.
For those who prefer bullet points, here are the devices with factory images available as well as the build number for each:
- Nexus S (soju): Android 4.1.1 (JRO03E)
- Nexus S (sojua): Android 4.1.1 (JRO03E)
- Galaxy Nexus (yakju): Android 4.1.1 (JRO03C)
- Galaxy Nexus (takju): Android 4.1.1 (JRO03C)
- Nexus 7 (nakasi): Android 4.1.1 (JRO03D)
If you need to get back to the way things were when you first got your device, you can download the images from Google's download site right here.
