One of the more annoying things that smartphone hardware manufacturers do from time to time is to restrict devices from using certain wireless bands even though technically the hardware supports those bands. This is particularly common from companies like QUALCOMM where they restrict hardware from working on wireless frequencies abroad.
What that means for the user is that if you travel your phone may not work in certain countries even though the hardware is capable. A process for removing these software imposed restrictions on various Qualcomm devices has been published with the goal of letting your device connect to any wireless frequencies it is capable of.
There are some caveats to the process that anyone considering trying it out needs to know. One major caveat for those who like to keep devices stock is that you do need a rooted device. The other drawback is that the process of removing the limitations is a long one.
The entire process has 36 steps and as with anything that requires a rooted device and modification of system files, there is always the chance you will make a mistake that may render your smartphone useless. Those brave enough to try it out can get the required files here, and be sure to let us know how the process goes.
