The Nokia OST tool or the Nokia Online Service Tool (OST) is an official firmware flash tool for all Nokia Android devices. OST tool can flash Nokia firmware with .nb0 and .mlf extensions and you can use it to update your phone or restore it to stock. The tool detects Nokia smartphones automatically when they are in the Download Mode. You can download the latest Nokia OST Tool 6.3.7, OST LA 6.2.8, 6.0.4, and 6.1.2 with crack from below. Please note that the OST Tool works only with Windows 32-bit and 64-bit and is not available for macOS and Linux.
Please note that you cannot use the official version of the Nokia OST Tool as it is meant to be used by certified engineers at Nokia service centers. If you use the official tool without patching with a crack, you will be prompted to enter a user login and account password. Once you replace the original OnlineUpdateTool.exe and MobileFlashDll.dll with the cracked versions, you can use the OST Tool without login credentials like username and password.
If you have the latest Nokia Online Service Tool crack, you can easily use it to flash firmware without having an account ID and password. If you try launching the program without the correct login or patching the tool with the crack, you’ll get an insufficient permission issue in the OST Tool.

Hi, if your Nokia 2.3 already has Android 10 and you are having issues, you should perform a hard reset to fix them. Nokia OST LA doesn’t support MTK phones.
