How to download and flash stock ROM
Run Nokia Care Suite software and double-click on theData Package Manager category. Make sure that Nokia Care Suite Server is selected and click on Ok.
* If for one reason or another, the authentication with the Nokia Care Suite Server is not performed, so click on Work offline and on Ok. In the top left of the Data Package Manager window, click on File, on Work Online and on Ok.
* Fill in the two parameters Product Type and Product Code. Click on Search button. Right-click on the file found and click on Download Selected and wait the completed download to 100%.
* For only those, who have downloaded Stock ROM without using the Data Package Manager category, you must copy the downloaded files in the following directory:C:/ProgramData/Nokia/Packages/Products/RM-XXX(where XXX is your RM (RM-XXX = Product Type, and you can find your RM with the link Product Type & Product Code), for example for me with my Nokia X it is RM-980).
* Run Nokia Care Suite software and double-click on the Product Support Tool For Store 5.0 category. Click on Work offline. Stay in mode No connection.
In top left of the Product Support Tool For Store 5.0 window, click on File and then on Open Product. Find your Android Nokia, or in the Filter box, tap on keyboard the Product Type of your Android Nokia (in my case, a (RM-980) Nokia X) and select your Android Nokia. Then click on Open. Click on Programming, and then click on Recovery.
Click on Update list. Select the Stock ROM downloaded. Click on Start. Wait a little that Product Support Tool For Store 5.0 verifies of data Packages integrity then it starts flashing operation, and it will show you an error (it indicates that the application has lost the connection, but this is normal because the phone is not connected).
Connect the USB end into the USB port of your PC. Turn off your Android Nokia. Press and keep the Volume Down button and the Power button. Once a vibration felt, release the Power button. Release the Volume Down button after 15 seconds. Connect the other USB end to the USB port of your Android Nokia. Click on Retry in Recovery window.
If a error message like this during flashing:"MSG_INVALID_SIZE_SECURE_FLASH_RESP: 0x00040006" If that happens, try changing the USB port where your Android Nokia is connected. For example, if it’s a USB 3.0 port, try to connect it to a USB 2.0 port.
* If a message like this during flashing: "You have chosen not assigned product code for this device, do you wish to continue?" This is normal, it just means that the Product Code/Stock ROM chosen does not matches with that of the Android Nokia. But do not worry, this is quite normal. Click on OK.
* Wait the flashing process. Click on Close.
* Congratulations the process of flash is complete.
