How to restore HTC Sensation 4G to stock rom

The following is a step by step process of restoring the HTC Sensation 4G (T-Mobile) to stock ROM. Sometimes a factory reset does not fix the issue with the phone. You will then need to perform a restore to stock ROM to fully recover it. Or if your phone is bricked during flashing, restoring to stock ROM may also fix the issue. I have personally tried the below steps and it worked for me. 

  • Make sure HTC USB driver is installed on your PC
  • DownloadHTC Sensation 4G T-Mobile stock rom on your desktop
  • Connect the phone through USB port. Run the RUU file and follow its step to update the HTC phone.
  • If you run into error 155 during the process, do not exit the program. Navigate to C:\Documents and Settings\(User name)\Local Settings\Temp and find a folder created several minutes ago with a name starts with "{". There should be a large file (about 370MB) called in its subdirectory. Copy it to desktop and rename it to
  • Connect the HTC Sensation phone through USB port. Turn on USB mass storage mode. copy the file to the phone's sd card root directory
  • Reboot the phone into hboot by restarting the phone while holding down volume down button and power button.
  • hboot menu will prompt you on whether you would like to start update. Choose Yes by pressing volume up button.
  • Sit back and wait for the process to finish. Phone may reboot itself during the process. It will indicate "Update Complete... Press Power to reboot" once it's done. Now press power button to reboot
  • Congratuations, now you just flashed the phone to stock ROM (Android version 2.3.3)  



Here's a list of other error codes from RUU restore and possible resolutions:

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 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 140 (Bootloader Version Error):
The rom update utility cannot update your android phone. Please get the correct ROM update utility and try again.
You will get this error if you're installing an older/differently branded firmware to what your phone's bootloader identifies itself as. It refuses to downgrade. You need to first downgrade the firmware, change bootloader.

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.
Alternatively (in some cases) right click on the file and choose "Run as Administrator".
Or use the -> flashing method.

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.
