How To Install OS 10.3.1 On Your BlackBerry 10 Device Using Sachesi

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?

Rest assured we’re here to help. Here is a method which enables you to update your device to the latest version, in the event your carrier has not released the update.


Before we begin, please be advised this is a guideline only. You must exercise caution while performing all actions. Always backup of your device first. BlackBerryCentral will not be responsible to any failure/damage that may be caused to your device during the process.


Required Tools

  • Download and install Sachesi for Windows or Mac (current version is v2.0.0 RC).
  • Micro USB Cable


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 510 / 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.

  • Once the download completes, navigate to the Install tab.

  • Select Install Folder. In the file explorer window, navigate to the folder where you saved the downloaded and press Select Folder. The installation process will be carried out now.

  • 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.
