CWM Recovery for the HTC One smart phone is now available for download. The CWM recovery will allow you to flash custom firmwares and patches that otherwise cannot be flashed normally. You are required to have a unlock bootloader. You can get it unlocked from htcdev. Here are its installation instructions.
* Make sure fastboot is unchecked in power options and turn phone completely off
* Boot into HBOOT then Fastboot
* From fastboot. Use command “fastboot flash recovery recovery.img”
I highly recommend using a file manager like AROMA filemanager, which can be downloaded from here.
