I am writing this awesome tutorial in credit to BlackBerry Central. The BlackBerry Os Upgrade is available to all BlackBerry 10 users all around the globe­.

The BlackBerry Os 10.3.1 enhance some basic features which are absent in the Os 10.

BlackBerry has officially announced the launch of the much anticipated OS 10.3.1 today, and as we all know, an over the air (OTA) upgrade availability is subject to carrier certification and approval. So what if you’re among the unlucky ones and your carrier hasn’t released this update as of yet?

Upgrade Process

  • Connect your device to your computer with your Micro USB cable
  • Launch Sachesi
  • Select the Search tab


  • Search for available OS updates by other carriers. You can do that by entering the country and carrier codes under “Whitelist Settings” section.


  • We recommend using the codes 234 / 010, and selecting the device you’re attempting to upgrade
  • Press the Search button. At this point you should see the available OS version at the right hand side of the screen. If you see the correct version, continue to the next step. Otherwise, verify the country/carrier codes match the above image.
  • Select Download. Now the OS will be downloaded to your computer.

  • Patiently wait until the new version is installed on your device. (This may take up to an hour or so. Do not use your device during the entire process.)
  • Once the installation is done, your device will restart.

Welcome to OS 10.3.1

As BlackBerry 10 builds are global versions of your model, there is no problem to put codes of other countries. The only condition is that you have to make sure that the device type and variant are identical to yours exactly.
