The first thing to do in order to power up the performances of your Sony Ericsson Xperia Arc handset is to learn how to unlock its bootloader. It’s an easy process, but you may wreck your phone if you don’t know exactly what to do. Therefore, during this guide, you will be able to follow a few steps which will show you how to safely unlock the Arc’s bootloader in just a few minutes and without having any subsequent issues. Further aspects are detailed below, so take a look and see if you can handle it.

First of all, you must know that you have to unlock the Sony Ericsson Xperia Arc bootloader if you are looking into flashing a custom ROM (like CyanogenMod) on it. For those who don’t know, CyanogenMod is an after-market distribution of the Gingerbread OS, offering features not found in the basic version of the software, leading to a powerful smartphone. Also, the phone needs to have an unlocked bootloader if you want to unchain it from all those annoying factory restrictions, or if you want to gain more control over its internal system.

It’s important to know that each time a phone is released it comes with a locked bootloader, just like a default setting. The only way in avoiding this is if you can buy an unlocked phone straight from Google, but this is happening rarely. For a better view over the whole concept you may compare your Xperia’s Arc bootloader with the one you have on your computer. When the device is first powered on, it usually does not have an operating system in ROM or RAM. That’s why it must execute a small program stored in ROM and a few data in order to access the nonvolatile devices from which the operating system programs and data are loaded into RAM.

That’s it; the Sony Ericsson Xperia Arc bootloader should now be unlocked.
