The Sony Xperia ZL2 SOL25 reset is much like all the other mobile phones in the Xperia range of mobile phones. The Sony Xperia ZL2 SOL25 can be reset by way of the menu and also by way of the code settings. There is also the option for a factory reset by button pressing sequences as well as by software such as the PC Companion software.
The phone is much like the Sony Xperia M4 Aqua and the Sony Xperia M4 Aqua Dual mobile phones which will use the same reset process. Note that much like the other mobile phones in the range that once the data and settings have been deleted the data and settings cannot be recovered again. This is normally done only when people sell their mobile phone and need to clear all their person data. Below you can see how this is done and the options available when doing a reset.
