Hi guys, I recently screwed up flashing a new ROM and now I can't boot into recovery so I'm trying to flash a new twrp via fastboot. However, upon plugging in my HTC one I see fastboot USB yet no toolkits show that it is plugged in or recognized. I have installed various drivers and also the HTC sync manager however I still can't seem to flash my recovery.
My model is an international one and sadly it is S-ON, bootloader unlocked and rooted, HBOOT 1.44.
Any help would be appreciated.
