Nexus 4 Android 4.3 system dump leads to flashable ROM


A man by the name of Jeff Williams purchased a Nexus 4 from a Googler and posted to Google+ asking if Android 4.3 was already out. Of course, it wasn’t, but his screenshot showed Android version 4.3 on the device. As expected, many called him a liar. Changing the build.prop was quite easy. But many also noticed the new kernel and radio, making the possibility that it was real much higher.

Those who believed him started trying to help, and the learning process began. Eventually, they moved to IRC and a bunch of developers taught him how to do a system dump. In the end, JWR66N proved to be a legitimate build of Android 4.3.

Developers have released flashable files based on this dump, so if you’re willing to get your hands dirty, you can get this ROM running on your own Nexus 4. If you want to give it a try (and remember, it’s not quite a finished build), head to XDA in the source links and get flashing!

Now we wait to see if Google will even acknowledge the existence of Android 4.3. They have an event scheduled for July 24, which will probably see the announcement of Android 4.3, but it’s strange to see it leak and Google to say nothing. Hopefully we’ll get a final build and source next week. Other devices need some lovin’ too.

If you’re a Nexus 4 owner, will you flash this? If you already did, what do you think? Is it a big update? Leave a comment with your thoughts!

    Seems it’s 50/50 of whether it works well for people or not. Some people say it’s awesome! Some people have trouble getting root to work. And some people have call audio issues.

    I attempted to flash this and it booted/ran just fine but I had both the root and call audio issue.

    My call audio issue could have been related to the radio i was running. I’m still running the .33 radio and I didn’t have time to test with others. So that issue *could* be attributed to that.

    The root issue is supposed to be fixed by flashing an su.zip file but this still doesn’t seem to work for everybody. It didn’t work for me.

    For now, if you’re the kind to flash things like this, go for it but immediately check for these issues before you invest much in it. If these issues don’t hit you, then I believe it’s daily driver worthy! If you don’t want to fuss with it, give it another 24-48 hours and these problems will probably be more reliably resolved! :-)

      Bingo. Flash if you want to mess around, wait a while and daily driver ROMs will be released.

      The audio issue is directly related to the radio. There was a patch for 4.2.2 to fix this very issue when using the .33 radio. I flashed this yesterday and root was not there but easily fixed it by flashing su.zip. Not sure why it did not work for you. Did you flash the new radio and bootloader as well?

    Wow.. Lucky guy…

  • hurric

    I’d rather wait since updates come relatively fast (even though I’m in Canada) and also this is my only phone so if anything stops working, then I’m screwed.

  • donger

    This mean it’s closer to be release.

  • Coreblog

    Nice Post basically i’m using nexus 4 and i;m happy to see this review, keep it up

  • nexus

    i flashed it…it dissapointed me my nexus 4 now lag and slow down sometimes for example:when when u press the home button to return to the home screen it takes about 0.5 sec to return and the animation around the home button shivers :) (unlike the 4.2.2 which made the nexus 4 smoother than ios)

  • John loewen

    I flashed. Radio not LTE compatible. Baseband updated. Rooted. I don’t notice any real difference. But I enjoy updating before it is official.
