    Hello, need a real quick help. I am again sorry if not posting on the right thread.
    Say everything goes smooth on me installing Ubuntu on my Nexus 4 and then back to Android 4.3 because some of my good apps are missing !

    Will above process void my warranty (both hardware and software) and automatic android updates ?

    Thank you already

    Had a bit of luck, got the thing unlocked, but it chokes on the fastboot-windows boot recovery.img. The command prompt responds with okay twice, but the unit just goes black, and doesn't seem to do anything. I can reboot it from the power button (although it takes a while to do anything). But I seem to be stuck. Any ideas?

    That is why I read from page 12 going backwards! Thanks for reposting that, as my 4.3 OTA worked fine except it wiped TWRP off of my phone, and I was wondering why I could not get it back. Now just waiting for Koush's final 4.3 root program.

    Is this the one we need? Because I think it's updated now.

    If you select "READ MORE" under the description of the superuser app in Google Play, there is a link for unrooted devices. This is Koush's (non-beta) superuser program that is compatible with Android 4.3. I just followed the "Root it" section of the "Unlock and Root" instructions at the top of this forum, except I used the superuser.zip I got from Google Play (looking at the file size, they are both probably the same file anyway), and now I am rooted with superuser program version 1.0.2.1. My apps that require root access all seem to be working fine.

    Manual installation with the recovery zip:

    After reading through a ton of conflicting information, I came to the conclusion that the only key is to have everything absolutely stock, except for TWRP installed and optionally be rooted and have an unlocked bootloader (which was exactly my case). I updated to TWRP 2.6 before I did the OTA a couple of days ago to insure maximum compatibility. My update from 4.2.2 to 4.3 using the OTA went flawlessly.

    I read after rooting 4.3 one was unable to update the binaries? What should I do if that happens?

    Also note that there are SDK updates for Android 4.3 (toolkit programs and Windows Drivers).

    ./fastboot-mac boot recovery.img
    downloading 'boot.img'... OKAY
    booting... OKAY

    The phone appears to be booting, says "Google", then nothing! I've done something wrong, but what?

    Read a few posts up. Here is the windows version of what works. Can't speak for the Mac:

    fastboot-windows -c "lge.kcal=0|0|0|x" boot recovery.img

    If that does not work, the OS drivers, the various platform command executables, and the TWRP recovery that you download via the links in the guide are old or very old, and you may likely have issues with Android 4.3. They worked perfectly for me on Android 4.2 and 4.2.2, but I was having problems with various commands (fastboot, adb, etc.) on 4.3 (There were some major security related changes), but after downloading the SDK directly, which gives you the latest windows driver and the latest platform commands, and then installing the current version of TWRP, it alleviated all those problems. Also, there is an update manager built right into the SDK, so it is easy to stay current. There is also a version of the SDK available for the Mac.

    Hey guys, need your help.

    I accidentally flashed a 4.3 kernal on AOKP 4.2 - whoops!
    So, now when I try to boot my nexus 4, all I get is the google sign with unlocked symbol for about 4-7 seconds, then nothing.
    I cant get to fastboot, or TWRP recovery.

    What should I do to get a working phone (without loosing SD card stuff, etc)

    Thanks in advance - sorry for the noob questions

    fastbood boot recovery.img was just showing a BLACK SCREEN to me, it does work with this command instead:

    fastboot -c "lge.kcal=0|0|0|x" boot recovery.img

    This is important so you should add it to your guide

    I am having problems with this. My nexus 4 like most peoples is stuck at the cross stage. I have sent it away and they said it had water in it????!! Personally dont believe that as it still has no dispaly problems etc. I can get to the start mode with the command guy however it does not start up from there. Therefore I decided to try to follow the advice on the forum. I have tried to download and follow the instructions (doesnt help that im dyslexic and dyspraxic!). I manage to get to the command page but I cant even get it to do the fastboot devices. I have reinstalled drivers several times. And still it wont fastboot devices let alone get to the next stage.

    I feel to smash the effing thing up soon so would really appreciate some help. please bare in mind as mentioned above i am dyslexic and am finding this very stressful thanks in advance

    I keep seeing this posted, but with no explanation of why it's necessary with some Nexus devices. -c option is to override kernel, beyond that, no idea. Enlighten us?

    Don't know, but what is interesting is that between updating my SDK and upgrading to Android 4.4, I can now use fastboot by itself again without all the extra "stuff" on the command line.

    It is always a good idea to update the SDK before working with a new version of Android. If you have the full SDK, there's a tool to do so in the /tools/ directory (Google for details).

  22. pjc123's Avatar
    Yes, I am aware of the tool. Everything on my computer was updated when I was on version 4.3, and I still had to do the longer fastboot command. Something was fixed in either 4.4, the SDK, the Windows drivers, etc., since I went to 4.4.

    THANK YOU SO MUCH!!! I finally was able to follow your extremely thorough directions to restore what I stupidly caused (proving once again "you are never to old to learn something stupid.") I was overwhelmed by much frustration, and too many options for successful restores. I always have been a fan of the manual clean code to sort out the garbage getting in the way.You successfully explained how to get back to a fresh start, and my tablet is now zipping along quite nicely (which is all I was trying to do when I messed it up in the first place.) Live long, prosper, and keep helping the masses of nongeekdom (I am a citizen of that foul space.)

    Is rooting reversible? There is s setting in SuperSU that says "Full Unroot." Does that actually work? I thought rooting was permanent.

    Unrooting is very possible, and SuperSU's Full Unroot works well. "Root" is just the su binary and a management program, take those away and root is gone, of course this will not undo any changes you made with root access.

    Remember this is a Nexus device... A few clicks and your back to stock anyways.

    Out of curiosity, why the concern with unrooting?
