How to Unlock Xperia x10i, x8, pro, and x10 mini BOOTLOADER

Bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, Smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader. This is one reason that all Android phones have different Custom ROMS developed due to the high variance of processing hardware present on the device. The iDevices running iOS somewhat share the same hardware specs and hence you don’t see much variance in their bootloaders.

Bootloader is usually locked on an Android device because it’s an open source OS, still the manufacturers want you to stick to their Android OS version specifically designed for the device. In order to apply this concept, manufacturers lock the bootloader. With a locked bootloader on Android devices, it is virtually impossible to flash a Custom ROM and forced attempts void warranty as well as usually end up in bricks. Therefore, the first step is to always unlock the bootloader. 
What Does it Mean to Unlock the Bootloader?
Unlocking the bootloader is the first step towards gaining root privileges. Some developers and enthusiasts unlock and root in order to experiment with applications or with custom builds of Android. Needless to say, you should not attempt to unlock the bootloader unless you know what you are doing.


Warning: Unlocking your phone’s bootloader voids its warranty. It also completely wipes (formats) your Android phone’s internal memory including applications, contacts, SMS and MMS messages etc


For Xperia X10, X8, Pro and X10 Mini Only
Hope you have Root your Sonny Ericsson Xperia with the tutorial I posted HERE, the next step to install Custom Rom to your phone is to unlock the Bootloader.

    2. You have a good question but why i ignore it since is dat it was not placed in d appropriate thread 4 others to benefit 4rm my reply.
      When, bb 10 daily plan of *599*3*2# automatically turns it into a normal data bundle and therefore, you may not be able to use it as a bis plan on your bb device.
      To use it again on your bb device just activate another bb daily plan by dialing *499*3*2# or Send COD to 399, costs N100 and it will be reactivated on your blackberry device.
