Sony XPERIA Z5 is Sony Mobile flagship for 2015. It has large and quality 5,2 inch display, powerfull octacore Qualcomm Snapdragon 810 CPU, 3 GB RAM or 23 megapixel camera. Sony XPERIA Z5 is also water resistance. Below you can find the latest firmware for the phone and also two tutorials/manuals - how to unlock the bootloader and how to backup the original firmware customization.

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. All referenced files are determined for Sony XPERIA Z5 E6653. So, what can you expect in terms of mentioned manuals / tutorials?
