So, I understand that you can flash a custom recovery using DD. I have done this on my Nexus 6p, with an unlocked bootloader.
My carrier is Verizon, which loves to lock down bootloaders. I have another phone, an HTC One M7, which has been branded by Verizon. I have gained temporary root access using Kingroot. I am wondering if maybe I could flash a TWRP build to
/dev/block/bootdevice/by-name/recovery. I am afraid that this will brick it though.
Even if it flashed and booted successfully, would it even work to flash a custom ROM?
Thanks for any helpful answers
