Phone stuck on "Entering Recovery". Help!!!

[Simson_Halder]

Hello folks,
I had an old HTC one M8 running android kitkat. I've rooted my phone using kingo root app then installed flashify. I downloaded the latest TWRP 3.1 and also ensure that the version was correct for the device. After installing the img file using flashify my phone restarted and stuck with a dialogue saying "Entering Recovery". I've gone through a similar post where a senior member said to hold the power button until it reboot up. That method is not working for me.
I would highly appreciate and be pleased if anyone can help me out.

Is your bootloader locked? If so, that isn't the proper procedure for installing TWRP on this device. You can't install custom recovery on this device, unless you first unlock the bootloader.

Hold power+ vol up to force a reboot (may need to hold the buttons for a minute or so in a "stuck" condition). Once the screen goes dark indicating a reboot, let go of the buttons, and only hold vol down, until you see the bootloader screen. From there, if the bootloader is locked, unlock it using the HTCDev.com process, then wipe cache and flash TWRP with fastboot.
