Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
Error code 2002-4301 (range 2002-4301 to 2002-4500) on Nintendo Switch 2 and Nintendo Switch occurs at startup, when using amiibo, or during a save data or user transfer. Restart the console, test the microSD Express or microSD card, and check the source console for corrupted data.
Safety first
Stop and check this first
- Do not open the console casing if 2002-4301 to 2002-4500 continues without a card or in system memory; book an official repair with Nintendo.
- Restoring factory settings without deleting save data in recovery mode makes all software on the microSD card unusable (except screenshots and videos) and should only be used if you are keeping the console; use a full factory restore if selling or giving it away.
Safe checks you can perform
- Restart the console or hold POWER for 12 seconds
- Reseat, format, or remove the card and download to system memory
- Check for and delete corrupted data on the source console
- Restore factory settings without deleting save data for 2002-4315

Nintendo repair request for startup or card-reading failure
What they doIf 2002-4301 persists upon startup without a microSD card, or continues across multiple supported microSD or microSD Express cards and when downloading directly to system memory, Nintendo asks you to send the console for repair and include one or two of the problematic microSD cards.

Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Restart the console or hold POWER for 12 seconds
- Who:
- you, on the console displaying 2002-4301.
- How:
- if the code appeared at startup or while using amiibo, restart your Nintendo Switch 2 or Nintendo Switch; if it is not responding, hold the POWER Button for twelve seconds to force it to shut down, then power it back on.
- Result that matters:
- seeing whether error 2002-4301 clears after restarting and checking for the latest system update.
- If the error no longer displays:
- confirm the latest system update is installed and continue using the console as normal.
- If the error displays again after restarting:
- check whether a microSD or microSD Express card is inserted.
- Evidence to keep:
- when 2002-4301 occurred and whether a twelve-second forced shutdown was required.

Reseat, format, or remove the card and download to system memory
- Who:
- you, if a memory card is present on 2002-4301.
- How:
- remembering that Nintendo Switch 2 only supports microSD Express cards, remove and reinsert the card, format it, or try a different card; finally, remove the card and download the software directly to the console's system memory.
- Result that matters:
- determining whether 2002-4301 belongs to the memory card or persists in system memory.
- If it works with another supported card or in system memory:
- the previous card was the cause.
- If it persists with multiple supported cards, in system memory, or at startup with no card:
- the console needs repair.
- Evidence to keep:
- which microSD or microSD Express cards were tested and the result in system memory.

Check for and delete corrupted data on the source console
- Who:
- you, on the source console after a suspended transfer.
- How:
- when a Save Data Transfer on Switch 2 or a User and Save Data Transfer on Switch is suspended, check for corrupted data on the source Nintendo Switch 2 or Nintendo Switch console, delete any corrupted save data found, and try to transfer the user again.
- Result that matters:
- clearing corrupted save data on the source console so the transfer completes without 2002-4301.
- If the user transfer finishes after deleting corrupted data:
- those files caused the interruption.
- If error code 2002-4315 is displayed:
- restore the source console to factory settings without deleting save data.
- Evidence to keep:
- which title showed corrupted data on the source console.

Restore factory settings without deleting save data for 2002-4315
- Who:
- you, on the source console if you are keeping it.
- How:
- power off the source console, hold down volume up (+) and volume down (-) while pressing POWER until recovery mode appears, then select Restore Factory Settings Without Deleting Save Data > Next > Restore Factory Settings Without Deleting Save Data.
- Result that matters:
- resetting the source console in recovery mode while keeping save data, screenshots, videos, and users.
- If the save data transfer succeeds afterwards:
- recovery mode cleared the 2002-4315 state.
- If the transfer error persists:
- Nintendo states the source console will need to be repaired.
- Evidence to keep:
- record of error code 2002-4315 and the transfer result after recovery mode.
All software saved on the microSD card (except screenshots and videos) becomes unusable; only use this if keeping the console.

What it means
Nintendo UK Support covers error codes 2002-4301 to 2002-4500 for the Nintendo Switch 2 and Nintendo Switch families (other console models may differ) in two situations: at startup or while using amiibo, and when a Save Data Transfer on Switch 2 or a User and Save Data Transfer on Switch is suspended. Code 2002-4301 alone never proves a part is faulty: it often comes from an unseated or incompatible microSD Express or microSD card, corrupted save data on the source console, or transfer code 2002-4315, which calls for a factory restore without deleting save data before repair.
Warnings and stop conditions
- Loweditorial warning
Do not open the console casing if 2002-4301 to 2002-4500 continues without a card or in system memory; book an official repair with Nintendo.

Symptoms and causes
Probable causes · in order
- Unseated or incompatible microSD Express or microSD card at startupCommon
At startup or while using amiibo, a poorly seated card or inserting a standard microSD card into Nintendo Switch 2 (which only supports microSD Express cards) triggers codes 2002-4301 to 2002-4500.
Evidence: Error Codes: 2002-4301 to 2002-4500 (Nintendo UK Support)
- Corrupted data on the source console suspending a transferPossible
When a Save Data Transfer on Nintendo Switch 2 or a User and Save Data Transfer on Nintendo Switch is suspended, Nintendo asks you to check for and delete corrupted save data on the source console.
Evidence: Error Codes: 2002-4301 to 2002-4500 (Nintendo UK Support)
- Transfer code 2002-4315 on source or startup error without a cardLess common
If error code 2002-4315 appears during transfer, the source console needs a factory restore without deleting save data; if the error persists or occurs at startup without a card, repair is needed.
