All Sony Ericsson HOW TO FLASH STOCK ROMs WITH FLASHTOOL Guide 100% Working

I would like to thank Androxyde for the FlashTool

***BEFORE YOU FOLLOW THIS TUTORIAL MAKE SURE THAT YOU HAVE INSTALLED SONY PC COMPANION ON YOUR PC***

HOW TO FLASH STOCK FIRMWARE (.FTF/ROM) ON YOUR XPERIA

1: First of all you need to make sure you download the LATEST Flashtool from Here

If it is your first time for your phone on the PC, install the flashmode driver, and then get the HW detection to work. Eg, install the driver, then turn off your phone, and then hold down the Down volume button and plug it in – windows will then go into hw detection and install the driver for the phone. It will try to check online, so skip that, and it will install the proper driver you just locally installed.

Thanks to Mobe1969 from the Whirlpool forum

NOTE: Been seeing people having problems flashing stock .253 based ROMs. Thanks to gm007 for suggesting to use the beta4 version of FlashTool if flashing stock .253 ROMs. You can download beta4 version from here

As you can see the drivers didn't install:


So here are the steps to install the drivers:
