Root method after schi559 upgrade 2.3.4

The upgrade process is actually very simple and I will not talk about it here. It is just to download the Kies selection tool on the official website to check the new firmware and then follow the prompts to upgrade it.

 

After i559 is upgraded to 2.3.4, The superoneclick cannot be used as the root user. The problem may occur during Step 6.

After searching online for a long time, I finally summed up an available method. The steps are as follows:

1. Download the attachment from my shared documents

I559_root.zip

You need one point.

2. Do not decompress the package and place it in the root directory of the mobile phone memory card.

3. Shutdown

4. Press and hold the phone volume down key + menu key (left-down button) + open key to enter the recovery mode of i559

5. Use the volume key to Select Apply update from sdcard

6. Press home (the key in the middle below) to confirm and wait for the prompt update complete

7. Select reboot system now and restart it. After the restart, an authorization application is added and the root operation succeeds.

In this process, I personally tried it.

 

However, after the upgrade, we found that the handwriting was not clear and sometimes restarted. It is estimated that Samsung's upgrade package was not well done. Stability when there is no 2.2.
