II. Root your phone.

1. Download the Z4 Root app either from the Market (if it is available) or download it from here (link updated 09/08/12) and use a file manager (Linda file manager or Astro file manager from the Market) to install it.

2. Plug your phone in via USB cable and mount the storage so we can transfer files to it.

3. Copy the .apk file over to the root of your sd card (not in any folder just on the sd card itself).

3. Download a file manager from the Market then open it and search for the z4 root apk file.

4. Install z4 root.

5. Open z4 root and click Root. Done!

III. (Optional) Install a Custom Recovery Image.

  • Artgnz

    I tried this on optimus T running 2.2.2 and i managed to get the Z4 root app into my phone and installed it but when i push root it tells me to enable USB debugging and when i do it still says same thing. i always have USB enabled but it still tells me to enable it. im guessing it doesnt work?

  • Dev

    I tried using this.
    When I clicked on Root it started some process and for more than 5 minutes its showing ” Atttempting to apply root”… What should I do ? How much time usually it will take to root ?

  • Janice

    It doesn’t work for my Samsung Exhibit 4G. It starts to run the root program than freezes and then locks up. I’ve tried at least 5 or 6 times. I’ve shut down any could-be interfering apps too. Oh well.

  • Ultimatespeedstanley

    mine says that this application comes from an unknown source, and for your security only applications from trusted sources can be installed and the only option is “OK”

  • Leo

    what is the benefit of root?
    is it safe to root?
    can I update my device later(original update by the manufacturer ) with no problems ?
