I have redmi 4 which was working fine. But it is now switched off. When tried to switch on it shows mi logo then android logo and again switch off. It is bootloader is locked, non rooted and usb debugging not enabled. So not able to connect via adb to computer. But only able to reach fastboot and recovery. And when conneted to computer via usb and fastboot via command prompt detects and shows the serial number. I'm tring to do something in short. Otherwise flashing twrp and then os again is long route; tried but in vain. As well as tried some YouTube,Google,Chinese Mi software too. Any help is appreciated.
