i am stuck in bootloop with no recov.img installed. My usb debug is off too.how enble usb debug in bootloader ?
First, unlock you bootloader. With your phone in the bootloader, connect it to you computer via USB. Download fastboot (just google "fastboot download"). Then open CMD or terminal, depending on what OS you have on your computer. Run
fastboot oem unlock.
Then download TWRP, found here. Make sure you chose the right device (whatever device you have). Download that. At your command line run
fastboot flash recovery path/to/twrp.img
