Google just dropped the full OS image for the recently announced at Google I/O Nexus 7 tablet. The image allows you to restore the tablet back to full stock Android 4.1 (build JRN84D) in case something goes wrong. This way, developers can tweak its internals without fearing a brick and users can always go back to something stable if a flash goes awry.

There are no surprises here - the Nexus 7 is a true Nexus device after all. Great job publishing the image promptly, Google!


It's interesting to note that the page name switched from "Factory Images for Nexus Phones" to "Factory Images for Nexus Devices" which made me realize and allow to sink in yet again just what exactly happened in the last 3 days.

Here's another interesting bit you probably haven't seen before - the Nexus 7's codename is "nakasi." Unlike the fishy variety that Google used with the Nexus phones, Nakasi is actually a music form. Can we expect to see its similarly named big, say, 10", brother sometime soon? If so, does anyone have any good codename guesses?


To download, head over to the Factory Images page and scroll down to "nakasi."

    This may be a dumb question, but could it work on an Asus Transformer Prime?

      Not in it's current state, but it is possible for it to be ported by some talented developers. The likeliness isn't high though. Once the AOSP source drops in mid-July, there's a much better chance of the Transformer Prime getting JB

    Great observation...

    But what caught my eye even more is that 4.0.4 was put up for toro (CDMA).  Wouldn't have figured Google would still continue for the CDMA devices, since they are "archived, for reference only".  Good to know even the archives will still be updated.

      Ditto, this is extremely good news. Hopefully Verizon Nexus owners won't have to wait another 6 months for Jelly Bean like they did for 4.0.4. Seeing as how current JB ports to the Verizon GNex are still not quite there. But that won't take long for the dev community considering how much they have already accomplished, so I am saying this in terms of those who don't root there Nexus. I got my dad's rooted so I expect I'll have him on a 100% functional and equally stable ROM before the end of July.

    actually, nakasi is the name in the sense that yakju/takju/mysid are the Galaxy Nexii... same with soju/sojus and the Nexus S and passion for the Nexus One. it's board name is "grouper" which is just as much a fish as all the previous ones have been (tuna for GN, herring for NS, mahimahi for N1, trout for G1, and goldfish for the emulator). not sure what the name of the Nexus Q is though, but most likely Google will keep this up

      Mind blown but probably cuz im stoned.

      Damn bro u went all into details that nakasi was some kind of fish thing. Nice this guy knows his shit here
