First of all one important thing - before you start to do anything with your phone, do the backup of your personal data. It is only for your safety in case that something goes wrong or any mistake happens. In that case you can use the backup to restore the data and try to do everything once again. Each tutorial has been done many times to verify its propriety, so just read carefully all instructions and continue step by step. For each of Sony (Ericsson) XPERIA smartphones we will provide a manual consisting of 4, 5 or 6 „HOW TO“ chapters. Our tutorials will be of course updated every time when Sony Mobile publishes anything new, affecting any of our topics. All important files have been stored on Google Drive, so there should be no problem with downloading. The major part of every file has been created by myself and every file has been tested on the corresponding phone. In this guideline related to the Sony Ericsson XPERIA Arc you can find some photos and videos showing how to proceed, but the most important thing are the below written manuals. All referenced files are determined for Sony Ericsson XPERIA Arc LT15i. So, what can you expect in terms of mentioned manuals / tutorials?

See Video Guide How to install firmware Sony Xperia Arc LT15 below:

How to install the newest Android 4.0.4 for Sony Ericsson XPERIA Arc LT15i
  • first of all, check your firmware version (if you already have the newest one, you do not need this tutorial)
  • download and install latest Flashtool from this v 0.9.13.0
  • download also latest Android 4.0.4 (mirror) for Sony Ericsson XPERIA Arc LT15i
  • paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool
  • open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok. Important - if you do not want to delete any data of your phone, just uncheck flashing userdata.sin file. All data will remain in your phone, but sometimes it can cause additional troubles. So it is better (and I recommend that) to do the backup of your personal data, than proceed with clean instalation and then restore your personal data.
  • turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding back button 
  • after few minutes all is done and your phone gets the new firmware
