Hello. I have a problem with the Sony Xperia Z3. Namely, the phone switched off at 60% battery charge and since then there is no reaction on his part.
When connected to a charger, either the red LED is still on or it blinks or flashes and the Sony logo appears and falls into the bootloop.
After connecting to a computer, using the Xperia Companion program and attempting to enter the flashmode mode, the red LED continues to glow and the green LED lights up to 0.1sec. and immediately appears red. The same with fastboot, only the diode on this part of the second is blue.
It was turned off when downloading a heavy (a lot of memory) game with a small amount of available memory on the phone (with 1.5gb of free space, but the game would settle)
The phone was loaded with custom roms (Android 8.1.0 and 6.0.1 on which it died) and custom recovery (the latest TWRP)
The phone had an unlocked Bootloader and was rooted.
PLEASE HELP!
