Hello,
Thanks to the_laser and Setool2 team it's now possible to fix boot in Sony Xperia XA and XA dual F3111 / F3112 / F3113 / F3115 / F3116 phones. If your phone can't be detected with battery due to for example damaged security units or "stucked" boot ( no device appears, when phone connected to PC ) - you need to open phone and connect testpoint to GND. Here is marked testpoint location which you should connect to GND (for example metal shield on the main board) and then attach usb cable:
