How to upgrade your Sherlybox to V2 software

Sherlybox V2 software is here! Now it’s time to upgrade!


Download Sherlybox V2 software from your Account page, select “Sherlybox” from the list of supported devices on the right-hand side:


It’s a large zip file which is over 1GB in size, containing entire Sherlybox system image. Once downloaded, unzip the “SherlyboxV2.img” file, which is 8GB in size. MD5 checksums are:

dfc40cf7f3782ebe978ca077343f3303 SherlyboxV2.img

On your computer backup all shared files from the old 1.6 are located at \yourhomefolder\\ – We recommend that you copy the entire “” folder into a different location on your computer.

Take out the SD card from your Sherlybox, located on the bottom:


Make sure SD card is unlocked for writing as shown below:


Next, burn the Sherlybox system image onto the SD card. Proceed according to your operating system’s prompts:

Burning the SD card image using Microsoft Windows:

    1. Insert the SD card into your SD card reader and check which drive letter it has been assigned. You can easily check this (for example G:) by looking in the left column of Windows Explorer. You can use the SD Card slot (if you have one) or a cheap SD adapter which fits a USB slot.
    2. Download the Win32DiskImager utility (it is also a zip file). You can run this from a USB drive.
    3. Extract the executable from the zip file and run the Win32DiskImager utility. You may need to run the utility as the Administrator! To do so, right-click on the file and select ‘Run as Administrator’.
    4. Select the image file you have extracted.
    5. Select the drive letter of the SD card in the device box. Selecting the correct drive here is very important as if you select the wrong drive, you may destroy important data stored on your computer’s hard disk! If you are using an SD Card slot which is built into your computer (if you have one) and you can’t see the drive in the Win32DiskImager window, try using a cheap SD adapter which fits a USB slot.
    6. Click on “Write” and wait for the write to complete.
    7. Exit the imager and eject the SD card.

Burning the SD card image using the Apple macOS:

  1. For GUI tools use ApplePi-Baker or PiWriter if it works on your macOS version – these tools haven’t been updated for the latest Apple OS versions yet.
  2. The “Terminal” method is quite straightforward. Simply follow these steps:
  • diskutil list

identify the disk (not partition) of your SD card. e.g. disk4 (not disk4s1)

  • diskutil unmountDisk /dev/<disk# from diskutil>

e.g. diskutil unmountDisk /dev/disk4

  • sudo dd bs=1m if=SherlyboxV2.img of=/dev/<disk# from diskutil>

e.g. sudo dd bs=1m if=SherlyboxV2.img of=/dev/rdisk4

This will take a few minutes, be patient until terminal displays a new prompt.

When you have an SD card ready, insert it into Sherlybox, connect the power and Ethernet cables along with the Wi-Fi dongle and you are ready to pair your Sherlybox.

Pairing your Sherlybox with organization.

Launch your Sherly Desktop app, available for Windows, macOS, and Linux at Account.

Make sure Sherlybox is powered up and connected to the same local network via a cable or Wi-Fi.

Select the organization from the list on the left-hand side that you want your Sherlybox to be assigned to (if you have more than one).

Click “add device” in the “Devices” section of app. You will be presented with all the Storage options:

Select Sherlybox and on the next screen, select “Pair”

Touch your Sherlybox top sensor for 3 seconds. At this stage, your Sherlybox will display a white, rapid-blinking LED light which signals that it is waiting for a pairing command from the Sherly Desktop app.

Once Sherlybox is found in the app, confirm that you want to proceed with pairing by touching the sensor once and pairing will be complete. Now, select it from your Devices list and choose the projects that you want to be synced on your Sherlybox.

From now on, all shared projects within the selected organization will be hosted on that Sherlybox, which will automatically sync all new files added by project members.
