First, good evening, who is reading my message at this time.
I have a Sony Xperia Xa model F3115 purchased at the store of light on the 10th of October 2016, the device in question was my father, but by an accident he ended up slamming the car door on his cell phone and ended up breaking the display (the glass remained Intact, but the liquid crystal vasou), for reasons of cost and financial indisposition at the moment, I acquired a spare part on the internet (full frontal), and I even replaced it since I have technical skills oriented to hardware, after replaced the piece everything worked 100%, the service was perfect. But I'm selling the phone since I do not like to have a fixed device (even if it was repaired in authorized assistance I would not have the phone), and the buyer (a friend of mine) was annoyed by the fact that the system had the ROM of Operator (of course), full of useless gadgets and gadgets that can not be uninstalled, and asked me to format with the clean system.
As I already did this in 2 xperia M4 and 2 Xperias Zq (also in the light), I repeated the procedure with Xa, using Xperia Firm and Flashtools to install the free firmware of operators in my device, I downloaded the global version And Journalist) for the model F3115 and started the process of updating firmware, the whole process was successfully completed on the computer, but when I took the phone to connect and started to configure the first steps I realized that it did not care anymore, No life signal, no vibration or image, boot image, only lights a red LED when connected to the USB cable.
I have already tried many repair tutorials on the internet already tried to disconnect and reconnect the battery, already tried to use the Xperia companion, already tried everything and simply nothing works. When you connect to the computer you will see a driver notification impossible to install and a device sound. I need an orientation on how to proceed
