{ EMMA } Sony Flash tool for Xperia™ devices

[ Edited ]

Apr 9, 2013

 

Hi Folks

It seems a lot of users are unaware of the Emma software by Sony. It provides us with the opportunity to flash stock firmwares of any customization on Xperia with unlocked bootloader. As many of you must be knowing that PC Companion and SUS could not be used to install official updates on devices with unlocked bootloader, Emma could prove to be a very helpfull tool.

 

Presently it's in Beta stage and supports a limited number of Xperia phones Check the List of supported phones

 

Flashtool preparation

  1. Download the Flash tool for Xperia devices.
  2. Unzip the file you downloaded and place it somewhere on your computer.
  3. In the unzipped folder, run Emma.exe.During the installation, make sure you remember the installation path:
    1. Default path in Windows 64 bit is: “C:\Program Files (x86)\Sony Mobile\Emma\”
    2. Default path in Windows 32 bit is: “C:\Program Files\Sony Mobile\Emma\”
  4. Copy the Customization.ini file. 
  5. Paste the Customization.ini file into the installation folder. The installation folder is the folder named Emma in the installation path examples on point 3.1 and 3.2 above.
  6. Click Start > All programs > Sony Mobile > Emma (if you used the default installation path from step 3 above) to start the flash tool

Note : If you do not place the Customization.ini file in the correct Emma folder, it would ask for Username and Password. You won't be able to use it then.

 

How to Flash using Emma

For a Video tutorial, check this Link

  1. Open Emma
  2. Connect a USB cable to your computer.
  3. Turn off your phone. and connect the other end of the USB cable while holding the flash key (for example Volume down). The flash key varies between models. For a complete key mapping, see thesupported phonespage.
  4. Screenshot showing the flash tool when a phone is connected.
  5. Select the software you want to flash in the Service list. The tool automatically detects the phone model and lists available software versions, which are called Services in this flash tool.
  6. Click on Apply Service. The phone will now be downloaded and flashed.
  7. When it finishes, you can disconnectyour phone from the computer.

Remember : The first time you start your device after you have flashed it, the boot-up might take a little longer than normal.

This thread was locked and don't know how come it's open again.

Both of you make sure you're following the steps correctly.

Have you pasted the customization file in the correct place ? without that you can't even run emma.

Phone should be connected in flashmode. Without that , Emma won't recognize a thing.
