Factory Reset

A factory reset reflashes JetKVM with the latest official firmware. Use it when you can't reach the device over SSH, want a clean slate, or are recovering from a failed boot.

The recovery procedure depends on which model you own:

Model	Recovery method	Image
JetKVM	DFU mode + upgrade_tool	firmware.img
JetKVM SDMMC	Flash a microSD card	update_sd.img.zip

Both images are served from the same endpoint, selected by the sku parameter shown in each section below.

JetKVM SDMMC: microSD recovery

JetKVM SDMMC boots from a microSD card. To recover the device, write a fresh recovery image to a card and boot from it.

You will need:

• A microSD card (8 GB or larger; UHS-I / Class 10 recommended)
• An SD card image writer — balenaEtcher, Raspberry Pi Imager, or dd all work

1. Download the recovery image

Download update_sd.img.zip from:

https://api.jetkvm.com/releases/system_recovery/latest?sku=jetkvm-v2-sdmmc

The archive contains a raw dd-format image. Most GUI writers can flash it directly without extracting.

2. Write the image to the microSD card

Flash update_sd.img.zip to the microSD card with your image writer.

Writing the image will erase everything on the card. Confirm you've selected the correct device before continuing.

3. Boot from the microSD card

1. Disconnect power from JetKVM SDMMC.
2. Insert the prepared microSD card into the device.
3. Reconnect power.

The device boots from the new image. Recovery is complete when the front display shows the device's IP address as normal.
