Nokia OST Tool [Nokia OST LA]

Nokia-Online-Service-Tool (2)

The Nokia Online Service Tool shortly referred to as Nokia OST Tool is a windows software application program used to install stock firmware on Nokia Android devices. This could be seen as Odin (Samsung) for Nokia devices.

The Nokia Online Service tool was never intended to be used by the public and that is the reason why when you try to run it on your computer, you will be prompted to enter credentials to proceed with using the tool. We think this is some sort of security mechanism which Nokia has introduced to make sure that this tool can only be used by its own employees!

But that does not stop our awesome developers from patching this awesome tool and thus opening the gates for all of us to use it. The patching involves simply replacing one of the files and deleting another in the Nokia OST Tool installation folder. Do not worry, we have covered every single step in detail in the below post!

Nokia Online Service Tool | Frequently Asked Questions

Q. Nokia Online Service Tool Password?

If the tool is asking for the password while you are trying to use it, it means only one thing: You have not replaced the patch file in the Nokia Online Service tool installation Folder. Read the ‘How to Install’ section carefully and make sure you have replaced the patch file.

Q. Nokia Online Service Tool asking for password even after replacing the patch file?

This can happen if you have forgotten to delete a file called ‘NokiaOnlineUpdateTool.exe.config‘. The file will be available in the folder where the tool is installed (which is usually C:Program Files (x86)OST LA). Please delete the same and you should be good to go.

Q. What type of firmware files does Nokia OST Tool Support?

The tool supports only official Nokia Firmware file types and they are .nb0 or .mlf formats.

Q. I am getting Error Code 2203 while trying to install the Nokia OST Tool. What to do?

The Error Code 2203 basically means that the user does not have sufficient permissions to install the program to the folder that contains the installation point or the temp folder. Make sure that you are logged in as an Administrator to install the programs on the computer.

Please note that the first boot after installing the firmware might take longer than usual. This is true for most of the Android phones and it is how it is expected to work. No need to worry, just wait patiently for a few minutes and your device will boot up just fine.

Please use the tool with caution. Using the tool with incompatible firmware or corrupt firmware might render your device unusable. Always make sure you have a full backup of your data while flashing stock firmware on your devices.
