x10Flash (also known as Flashtool is an update flasher developed by XDA-Developers forum member Bin4ry that lets you flash a new firmware to your XPERIA X10. The developer has just released the latest version of X10Flash (Flashtool) which is capable of flashing the latest Android 2.1 Éclair version of firmware to your device.

Please note that while the Flashtool is capable of flashing firmware to all XPERIA Series devices now, the firmware that we are featuring in this is post is only meant for XPERIA X10 and NOT for XPERIA X10 Mini / Pro or X8 so do NOT attempt to flash it to these phones, or any phone other than XPERIA X10.

To install this firmware update:

  1. Download the Sony Ericsson Xperia Flashtool from the link given below, and extract the contents of the zip file to a folder on your computer.
  2. Download one of the firmware versions listed below for your phone depending on its model.
  3. Place the downloaded firmware files in a folder called ‘firmware’ inside the folder where you extracted the flash tool in Step 1, along with the loader.sin files.
  4. Run the .bat file of the flasher and choose your operating system. It will prompt you to plug your phone in flash mode now.
  5. Turn your phone off, press and hold its back button, plug it into the USB cable and press enter on your computer quickly.
  6. Wait patiently till the firmware is flashed to your phone. Its screen will remain off and the only indication of activity on your phone will be the green LED staying on.
  7. Once the .bat file has finished flashing your phone, you will get a prompt. Press the enter key to close it.
  8. Unplug your device from your computer and wait patiently for it to reboot, and you’re done.

  1. am getting this while flashing:

    Error in processHeader : 995
    : The I/O operation has been aborted because of either a thread exit or
    an application request

  2. good day.anyone who can help me where can i download and where can i upgrade my v.16 to v.2.1 eclair. done with my pc companion but it doesn’t work.

  3. Worked Perfect. I found I was having problems until I wiped out all user data (Hard Reset). After that, it worked on the first try. 2.1 works perfect for me. I have an AT&T X10a and i have had no problems so far. Wifi, Bluetooth, 3G, and so on, no problems. All I had to do is input the APN settings manually, which I found on google in 1 minute. I also found that Time scape slowed the phone down a bit (even on 1.6), I dont use it anyways, so I just stopped it from updating automatically and removed it from my home screen. I love this update!!! Thanks Bin4ry 🙂
