I dowmloaded the application loader in my pc and followed the steps it says in the website. After that it says this is not available for my device. I am from Bangladesh and I have no authorized carrier support
Note: because you're just upgrading, you can skip Step 4 if you like. In addition, if your phone is from a different carrier originally, you will need to delete a file called Vendor.xml first. This file is located in the same folder as the Loader.exe file, so just delete it before running the Loader.exe file and you should be all good to go!
I hope that info helps!
