    How long does it take to root the phone??

    it only said “daemon succesfull” or something like that :S

  2. Pauweedsmoker says

  3. says

    if i root my optimus and overclock it how much performance can i get out of it? also what is the TOP reason I should root? If you could answer that for me I would be greatful and be willing to donate/subscribe/ or w.e you want :) thanks.

    • says

      The main reason for rooting is you can install Custom ROMs. Those ROMs have more performance speed, better environment, and more advanced options. And you can install some apps that need a root access. And also you can remove some system apps in your mobile.

  4. YandeX says

    I wanted to know if you can still doing Portable WI-FI hotspot after rooting. And also if after rooting the phone can be unstable or something similar. Thanks

    • says

      Rooting is just like unlocking your phone to install custom ROM’s or any other apps that need a root access. So, after rooting, wifi hotspot will perfectly work. And don’t in unstable.

    Trying to root but USB debugging is not enabled. This is grey in my phone, I can’t change this option! Somebody any idea?

    • Káldeus pap says

      At first connect your phone with USB cable to PC, on the phone select
      “PC Software” as connection type. After that check the debugging setting
      again, wouldn’t be grayed IMHO.
      On the next occasions will automatically switch to debug mode.

  30. Bertel De Groote says

    I read this topic and discussion with great interest. Unfortunately I don’t manage to root my LG (LGE400 – Android 2.3.6 Kernel: 2.6.38.-perf – GRK39F – Software V10s-FEB-11-2013).

    I disabled my virusscanner and firewall.

    I installed the latest versions of the LG USB-driver

    I enbabled “USB debuggin”, put the USB in mode: Software PC, etc.

    I downgraded to Version10c and, without success, gave it a try.

    The phone drives me almost to madness.

    If I understand the error messages correctly the necessary files can not be pushed to my phone.

    You’ll find those messages (Rosenberg method spectrum_roor_windows) underneath.

    All help will be very much appreciated,
