I need to ask you all for help.
Namely, I have Xperia xa1 dual sim g3226 ultra with an open bootloader.
Two days ago I tried to upgrade and get into trouble. I found firmware and flash it by Sony flash tool, but everything ended incredibly fast (about 15 sec) and now I have bricked devices.
The real reason is not clear to me, but now I can not get in fastboot or download mode, just got a red light when phone is connect to pc and "unknown devices" in the device manager.
Does anyone know if there is any solution for me or the Xperia must go in the Sony service.
