What’s Not Working:

Make sure you have installed all your USB drivers for the Sony Ericsson Xperia Acro S to connect it with the computer. Download Sony Ericsson Xperia Acro S USB drivers! Apart from just the USB drivers, there are a few more things that you need to take care of.

  • This root method tutorial is only for Xperia Acro S LT26w and I am not sure if it will work on the other variants of the Xperia Acro S on other carriers.
  • Your phone should be rooted and have ClockworkMod recovery installed from before.
  • After installing this, your phone will not be detected by Sony PC Companion, because you will be installing a custom ROM.
  • Make a Nandroid (or any) backup of your previous phone set up before proceeding – for just in case anything goes wrong.

Step 9 – After the installation completes, go to “+++++Go Back” and reboot the phone by selecting “reboot system now” from the recovery menu. The phone will boot now and it might take about 5 minutes to boot on your first time. So, please wait.
