I have an old HTC desire HD that my assistant is using .
the phone is in constant boot loop , i tried to boot it in safe mode or even hard reset but i can't .
i tried the volume down ( then tried volume up ) + power button several minutes but nothing happens.
the phone boots extremely slowly ( 10 min ) , stays on for 30 seconds then reboots .
what can i do ?
how can i root and flash if it keeps booting ? i cannot manually hard reset it .
it doesnt go into fastboot , FACTORY RESET , etc ..
Tried factory resetting through ADB?
3 months later
try to use adb and use this command adb reboot fastboot it should reboot into fastboot mode when it enter fastboot just flash the stock boot.img this should stop the boot loop
