This is my first time rooting my HTC One (T-Mobile) and have managed to unlock my bootloader and install TWRP Recovery. Long story short, while attempting to install the latest Android Revolution HD Custom ROM, I seemed to have wiped my whole phone clean and don't even have an operating system anymore.
How can I get the Custom ROM file from my computer to my phone if I don't even have an operating system to boot into? It would be no problem if this phone had an SD card slot, but it doesn't . The only thing I can boot into now is the TWRP Recovery.
I have tried using the MOUNT option in TWRP Recovery, but to no avail. I have also tried to download HTC Sync Manager and the computer still does not recognize my HTC One. All I need is for my computer to recognize my phone and pop up in Windows Explorer so I can copy it into my phone's internal memory and use TWRP Recovery to install the ROM.
P.S. I am using Windows 8.1 64-bit.
PLEASE HELP ME! :'(
