Clockwordmod Recovery Bootloop Error - hard bricked

    I had CM11 running pretty well but could not turn off the phone (it is a Verizon HTC One M8). On power down it would reboot itself into clockwork recovery and leave the screen lit. So I used it a couple of days with just keeping it charged that way, but eventually, (today) decided to try to tackle it.

    Unfortunately for me I ended up on a thread that I didn't realize was intended for tablets and used the following command in the terminal after rooting with SU.

    "echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0"

    Now my phone will not turn on, not with volume down, up, or both. I do get power down and power up chimes on my laptop if I connect the USB, but I am unable to detect the device to try to use fastboot or ADB.

    I am truly stuck now and considering sending the device to manufacturer for restock. Any help would be much, much appreciated

    Hi there and welcome to the site. I am sorry that you have found yourself in a dead end situation.

    As you said, you used commands that were not intended for your phone. This is one of the things that we all must be careful of. What may work for one device may brick another; as the partitions are different for all.

    If you can boot into fastboot/bootloader mode and your device is s-off, you _might_ be able to manually flash a custom recovery again. For this device the most successful has been TWRP. From there you _might_ be able to sideload a ROM from there. I am not sure, but it's a thought.

    good luck
