How To Gain Permanent Root on T-Mobile G2 / Desire Z without ADB

This is a guide for permanently rooting a T-mobile G2 with Visionary / gfree without the use of ADB. First we use visionary program to achieve the temporary root, followed by gfree to gain permanent root. This procedure has been tested on G2 but should also work with Desire Z as well.

Powered by the Qualcomm processor, HTC Desire Z also known as the T-Mobile G2, is one of the best slider keyboard Android phones available in the market. The procedure of permanently rooting the phone is a two step process. The first step involves the Visionary program (named after the phone HTC Vision / G2) to achieve temporary root and then followed by gfree to achieve permanent root. In case you have done an OTA upgrade to version 1.72 then first downgrade the firmware to the original flash ROM. The credit for this guide goes to XDA Forum Senior Member ianmcquinn.

  1. The first step is to install Terminal Emulator and a file manager from the Marketplace, such as, Astro file manager.
  2. Now insert the SD card to your computer and unzip the “root_files.zip” file (download link given at the bottom of this post) to this SD card (a directory will be created called root_files on the card). When done, unmount the SD card from your computer. Make sure that all the extracted files are directly inside the root_files folder and not in another subfolder inside it.
  3. Enable unknown sources (under Settings –> Applications) and USB Debugging (under Settings –> Applications –> Development).
  4. Using the file manager (we are using Astro file manager), navigate to the root_files directory on the SD card (created in step 2), and select “com.modaco.visionaryplus.r14.apk” to install the Visionary app.
  5. Launch the Visionary app and click on “Temproot now”. Leave the other settings unchecked. Visionary Desire Z Temp Rooting Desire Z
  6. Start the terminal app and type the following commands:
$ su

# cp /sdcard/root_files/perm_root   /data/local/perm_root

# chmod 777 /data/local*

# /data/local/perm_root

Here is the terminal output of these commands that you should see during this process.

The first command changes the rights to super user, the second command copies files to the directory /data/local/perm_root, the third command changes the rights of files in data/local, and the last command launches the script.

As the program is executed you will see a number of messages scroll by. Once you are returned to the prompt in terminal, you will have permanent root, as well as subsidy unlock and Super CID. Your phone is now rooted and you can verify having permanent root by holding the Volume down while powering on the phone (see S-OFF in the first line of the bootloader) or by installing SuperUser app from Android market.
