HTC One is all set to hit the UK market on 15 March, as smartphone buyers and cellphone carriers bid to stake a claim on the exclusive offers with the company's newest flagship smartphone. The internet is already abuzz with news of available basic hack tools from rooting and unlocking to installing custom recoveries and custom ROMs on the popular handset.

Prospective HTC One buyers can now get a glimpse of the available tools and the hacking methods used, by following our step-by-step guide below for rooting the phone using All-In-One (AIO) toolkit.

NOTE: Rooting is essential to gain full system access or root access for installing third-party root apps, custom ROMs and latest system tweaks. In addition, one can remove bloatware or unwanted apps to increase system performance, use data connection tethering (even if it is restricted by your carrier), overclock the device's processor and more using a custom kernel after rooting the device.
