Hi @Rczumberg,
Welcome to the ODK community! Whenever you have a moment, please take the time to introduce yourself here. Adding a picture to your profile is a great way to boost engagement and help us get to know you better.
Don't worry, your data might not be lost.
First, connect each tablet to your computer using a USB cable and ensure the tablet is set to "File Transfer" mode. Navigate to the ODK
directory on the tablet's internal storage and find the instances
folder, which contains all the collected form data. Copy this entire folder to your computer.
Next, download and install ODK Briefcase. Open ODK Briefcase, go to the Pull
tab, and select the folder where you copied the instances
folder. Then you will be able to download the data.
By following these steps, you should be able to recover and download your data. If you encounter any issues, feel free to ask for further assistance. Good luck!
