When a manufacturer builds a phone, these sizes are locked. If a phone has a 1GB system partition, you cannot install a modern custom ROM that requires 1.2GB—even if you have 10GB of free personal space. The Nokia Repartition Tool dynamically shrinks oversized, unused partitions (like userdata ) and allocates that space to crucial system partitions. Why Use a Repartition Tool on Nokia Devices?
: If the phone is stuck, you can usually force a reboot by holding Power + Volume Down for about 15–20 seconds. Storage Mismatch
Extract the downloaded tool and run the executable (typically repartition.bat or similar).
The primary reason users turn to Nokia repartition tools is to make room for larger custom ROMs. Many stock Nokia Android phones come with a system partition as small as 2.5GB and a vendor partition of 512MB. This is insufficient for many modern Generic System Images (GSIs) or custom ROMs, which often require 3GB or more. By using a repartition tool, you can increase these partitions, typically to 3.5GB and 1GB respectively, freeing up space for a new OS while potentially reducing the userdata partition.
The tool is maintained as an open-source project by developer RaghuVarma. You can find the latest scripts and instructions on the Official Nokia Repartition Tool GitHub How to Use (General Workflow) Boot to Recovery nokia repartition tool
Community developer RaghuVarma331 created the Nokia Repartition Tool specifically for the 64GB variant of the Nokia 6.1 Plus to resolve this limitation. The most common modification changes the partition sizes to 3.5GB for the system and 1GB for the vendor .
Because HMD Global does not release an official consumer-facing partition manager, the developer community relies on specialized service tools and command-line interfaces. 1. OST LA (Online Service Tool Large Assembly)
: The user boots into TWRP and flashes the tool.
Using a repartition tool is a high-risk procedure. Altering the partition table incorrectly can "hard brick" a device, making it permanently unbootable. It should only be attempted by those comfortable with command-line tools like Parted for Android and who have a full backup of their device. When a manufacturer builds a phone, these sizes are locked
A notoriously common issue across several generations of Nokia Android phones (such as the Nokia 6.1, Nokia 7 Plus, and Nokia 8 series) is a corruption of the partition table. Users often notice that after a major OTA (Over-The-Air) update or an improper factory reset, the system misreports the available internal storage.
Detailed academic "papers" specifically on the Nokia Repartition Tool are rare, as it is primarily a community-developed utility for hobbyists and developers rather than a subject of formal academic research. However, you can find high-quality technical documentation and release notes through community hubs.
: The script will automatically resize the necessary partitions. Reboot & Install ROM
Fix: Your bootloader is locked, blocking low-level structural modifications. You must unlock the bootloader or flash via a hardware EDL point to bypass this restriction. Conclusion Why Use a Repartition Tool on Nokia Devices

This article explores what this tool is, how it works, and how to use it safely to restore your device to peak performance. What is the Nokia Repartition Tool?
Now that your partitions are resized, you cannot use your old data. You must flash the OS (Stock ROM or Custom ROM) that corresponds to the new partition size. If you resized to fit a larger ROM, flash that ROM now.
A 64GB or 128GB device suddenly reports only a fraction of its total storage space in settings.
