Reflash a Collector SD card

Use these steps when ReefMind support asks you to reinstall the Collector software. You write a fresh copy of the Collector image to its microSD card, then set it up on your Wi-Fi again. You need a computer and an SD card reader.

1. Download the Collector image

Download the Collector image: reefmind-v5.0.6-golden-shrunk-firstboot-fix.img.zip.
Unzip it. You will use the unzipped .img file in step 3.

2. Install Raspberry Pi Imager

Download and install Raspberry Pi Imager from raspberrypi.com/software.

3. Write the image to the Collector's SD card

Writing the image erases everything on the card you select. Pick the Collector's SD card, not another drive.

Unplug the Collector, remove its microSD card, and insert it into your computer with an SD card reader.
Open Raspberry Pi Imager and select Raspberry Pi Zero 2 W as the device.
In the operating system selection, scroll to Use Custom and select the unzipped image file.
Select the Collector's SD card as storage.
If Imager asks whether to apply OS customisation settings, choose No.
Click Write, and let writing and verification finish.
Safely eject the card, put it back in the Collector, and reconnect power.
Wait about 5 minutes. On its first power-on the Collector sets up the new card and restarts once by itself.
Connect to the ReefMind-Setup Wi-Fi network and follow Collector setup to reconnect it to your home Wi-Fi. If the network has not appeared after 10 minutes, unplug the Collector for 10 seconds, plug it back in, and wait 5 more minutes.
