    I have not received the 4.2.1 update yet, so i'm going to ask this question before I do.

    I am unlocked, and have rooted/installed busybox via the nexus 10 root toolkit.

    If/When i get notified about the 4.2.1 update, and i apply the update, what will the result be? Will i have to re-root, and reinstall TWRP recovery? Or will this brick me?

    Been rooting for life but this is the first time i don't have a custom ROM on a device, so i haven't hit this scenario before.

    Hi Joe. I moved this to the All Things Root forum for you. If I remember right from my Nexus 7 days, it will unroot you. You can either wait until the firmware is available for download and use one of the tools to flash it, or wait for a zip to be made that you can flash in recovery. You can use OTA Rootkeeper to temp unroot and flash in recovery.

    Thanks. Sorry i forgot to post this in the root section.

    Yeah, i'm sure a rooted 4.2.1 will get posted somewhere soon.

    Got the update, installed it, verified with root checker that it had unrooted me, then used Voodoo OTA Rootkeeper to re-apply root. Checked again with root checker and am rooted again.:D


    Update: Lost my custom recovery so I ran the 1-click again... all is fine

    I just received the 4.2.1 OTA update. I am unlocked and rooted.....but no custom recovery like CWM. I preserved my root with Voodoo OTA rootkeeper as soon as I unlocked and rooted out of the box. My tablet info is version 4.2.1 and build JOP40D after the OTA, so no issues with the install. I lost root after installing the update but I was able to get it back with Voodoo. I verified root with root checker and terminal emulator and installed a couple of apps to make sure they got root access. Everything is good. This has been the easiest device I have ever had to unlock, root and update.

    Do we know if anyone is actively working on building a 4.2.1 stock rooted image?

    No one has posted anything on xda either.

    I saw that. But i was turned off by the mention that it is a "debug build". What does that mean? I don't want extra lag or anything because the rom has debug turned on.

    Not quite sure about the "debug build" but this ROM flies. I have had no lag at all. This is just as snappy as stock.... Maybe a little quicker.
