· The correct PC driver for your Android phone has been installed.
· The Android phone is connected to your PC using the USB cable. The PC must recognize the Android phone.
· Standby or hibernation mode of your PC has been disabled.
· Close all running applications on the PC.
· The Android phone screen lock has been disabled.
Important Do not interact with your Android phone unless the RUU wizard instructs you to do so.

1. On the Welcome screen, click Next to begin the RUU installation.
2. Check the listed instructions in the dialog box and make sure you have done them. Click Next to proceed.
3. A message will then be displayed indicating that the utility is verifying and acquiring information about the Android phone as preparation for the update process. Wait for this verification process to be finished.
4. After the verification process, current information about the Android phone will be displayed. Click Update to proceed.
5. Below the Android phone information, information about the current image version and the new image update version will be displayed. If you are sure that you want to install the new RUU, click Next to proceed.
6. A confirmation message will appear and show the time it will take to install the necessary files (including radio image) to the Android phone. Click Next to begin the update. A progress bar will run through the screen during the update process.
Note: In the middle of the update process, the progress bar may stop moving. This is normal as the RUU is automatically adjusting itself to complete the update process.

Almost all RUU-related errors can be recovered. When an error occurs, the utility will display an error message and provide recovery measures to allow you to continue the update process.
If errors cannot be recovered, please refer to the Q&A section for more details.
ERROR [110]: FILE OPEN ERROR
This error message indicates that the RUU lacks some specific files or they are damaged, so the RUU cannot continue with the update. You have to get the complete RUU package and try again.
ERROR [120]: MAIN BATTERY POWER
This error message will appear when the Android phone’s battery power is not sufficient (Batter power should be more than 30%). Although RUU will instruct you to plug in the AC adapter, it will still need to make sure that your Android phone has enough power to complete the update. (The Android phone cannot charge the battery when it is connected to the PC while installing the RUU).
ERROR [121]: SCREEN LOCK
This error message will appear when the screen lock is enabled on the Android phone. You should disable the lock status first before continuing with the RUU update.
ERROR [130]: MODEL ID ERROR
ERROR [131]: CUSTOMER ID ERROR
One of these error messages will appear when you use the wrong RUU to do the update. The RUU will check if the Model ID and Language ID are compatible with the Android phone. Make sure you use the correct RUU to update.
ERROR [155~159]: IMAGE ERROR
One of these error messages will appear when you use the incorrect RUU to update and the image file size is larger than the Flash ROM size. In this case, download the correct RUU version and try again.
ERROR [170]: USB CONNECTION ERROR
This error message will appear when the Android phone is not correctly connected to the host PC. It might be a USB connection problem or a PC USB driver problem. Make sure the Android phone is connected to the host PC correctly and/or check if the PC driver matches the Android phone.
