What is a Stock ROM and Its Advantages?
Well, Stock ROM or Stock Firmware is official software that comes with the specific Android OS version out of the box. OEMs designed the stock firmware for each model so that the stock firmware can work properly & remains stable for years with additional software updates.
Generally, it doesn’t have too much bloatware or any unnecessary customization options out of the box. The Stock ROM always comes with a locked bootloader and a stock recovery mode. It’s the best firmware that remains so smooth and stable for your daily usage.
Talking about the advantages, the Stock ROM offers a clutter-free stable user experience, future software updates via OTA, official software support under warranty, a locked bootloader offers a secure device state from third-party flashing files, improved battery life, optimized app operations, and more.

As this is a Full OTA package firmware, it contains the payload.bin file. You can extract the payload.bin file using Payload Dumper and flash using the Nokia Tool or compress the extracted contents as a zip file to flash using the Nokia Flash Tool (NFT) according to your choice. We’ve shared both of them.
- Payload Dumper tool is a Python-based program. Make sure to download Python and install it on your computer.
- Select the ‘Add Python to PATH’ option within the installer while installing Python on your Windows computer.
- Download the Payload Dumper Tool (zip) file on your PC and extract it.
- Here you’ll find out a folder called ‘payload_dumper’.
- Now, make sure to download the Full OTA Android 10 firmware package (zip) that we’ve already given in the download links section above.
- Once downloaded the firmware zip file, just extract it > Here you’ll get the ‘payload.bin’ file.
- Simply copy the ‘payload.bin’ file and paste it inside the ‘payload_dumper’ folder.
- Now, from the ‘payload_dumper’ folder, just press and hold the Shift key + Right-click on the mouse on the blank space.
- Select Open PowerShell window here > The Windows PowerShell window will open.
- Next, you’ll have to install the ‘Protobuf’ (Google’s Data Interchange Format) on your computer by typing the following command and hit Enter on the PowerShell window:
python -m pip install protobuf
- Once executed this command, the Protobuf will be downloaded and installed on your PC.
- Now, you’ll have to extract the Android OTA payload.bin file by executing the following command line:
python payload_dumper.py payload.bin
- The tool will now start extracting all the individual partition images from the payload.bin file. Let the extraction process complete.
- Once extraction completed, you can see the payload.bin extracted files inside the ‘payload_dumper’ folder.
