    any tutorial of how to put a custom rom? i want android 4.1

    • http://www.facebook.com/marcg210 Marc Goss

      Just got an ota update to 4.1.1 tonight.

  • http://www.facebook.com/pushtoexit Jonathan Prevost

    I have the lg op l9 only thing is my model number shows as p769. I just want to make sure this wont effect the process in any way.

    • Jey Wright

      Nope. I have the exact same device already rooted and over-clocked at 1.3 Ghz. I’ve use this exact same method to root mine. Just make certain you’re on the 10e firmware. Anything less than that expect to use as a “Gorilla Glass” coaster.

      • theorogelio

        I’m on the 10g firmware. I’ve lucked out then?

  • Patrick Irwin

    Yea there isn’t really any development on this device. If anyone knows of someone willing to develop for it (4.2 PLEAASE) I’ll gladly make a system dump for it.

  • Shrikster

    If you do a little bit of a research, it will be pretty clear to you that custom update roms wont show up before official update*or leak update*, specifically for MID RANGE PHONES.

    If you are expecting official update to show up soon, IN MY OPINION, it will at-the-least take 6 months from release date for LG to release official update.

    Since root is available, a recovery will be available soon, which raise “4.0.x” custom roms, which, mayhaps, will be like jelly bean, but not exact jelly bean.

    *and seriously, if you are upto “NO >( I TRUST DEVELOPERS MORE THAN YOU” xD huhhhhh…

  • Blackman

    So there is no Jellybean available for this?

  • https://twitter.com/zuqiu85 Thomas Lau

    I have a rooted LG optimus L9. I believe the firmware update to Jellybean is now available and my phone has been trying to update, but it fails everytime (I see the screen of the android lying down with a red exclamation mark). Have any rooted users been able to update successfully?

    • Steven Goff

      I have the same problem, haven’t found a solution yet and the system update popup is very annoying.

  • http://www.facebook.com/raul.mojica.792 Raul Mojica

    No Work for me… So sad!!

  • jova914

    lg optimus l9 from t mobile is supposed to have 10g firmware, can this be rooted?

  • AndroidIzekeo

    Just making sure, is this root safe? I have the p76910

  • Michael Cook

    The tmobile version of the LG L9 is the P769 variant not the P760. its the only variant that has NOT received jellybean yet and still has a locked bootloader so even if you do unlock it you cant flash any new roms to this phone

    this guide needs to get its facts straight

  • ratdoghippy

    I think this is just a scam thye person can not even speak right when writing out the instructions, and after re reading it several times it is clear to me he is not really offering anything
