When you first came to XDA Developers, the world of Android modification was likely very new to you. Custom ROMs, kernels, recoveries were all more than likely previously unknown. Compounding matters, these things pieces of development work often have different installation procedures, depending on target device.
If you are just beginning your Android journey and happen to own a Sony Xperia device, you might be interested in a guide by XDA Senior Member cy56. This guide is very newbie friendly, and it explains the process of backing up, wiping, and flashing everything for the first time.
The guide is thoroughly detailed, and contains specific sections for Xperia devices since the kernel flashing on these devices is not done through fastboot. Keep in mind that every firmware version and device are a little bit different. However, the guide begins with CM10 and ends on KitKat-based ROMs.
If you are an Xperia user and want to start the journey towards custom ROM and other tweaks, make your way to the guide thread to get started._________
