In case of trouble
First and simplest action to try is to disconnect the USB C cable connector from its port on
the back panel of the instrument. This usually helps.
But if your device lost power during the upgrade, the SD file structure was damaged, or the
firmware doesn’t boot up for any other reason, you can perform one of the two emergency
flashing procedures as follows:
First method:
just simply press the hidden reset button on the back panel of the instrument and it
will automatically flash with a randomly picked firmware .ptf file from the SD card
Firmware/ folder.
Second method:
download the Polyend Tool,
download a known working firmware file either from the Polyend website or one of the
previous beta .ptf files,
important:
remove the SD card from the Tracker,
connect your Tracker directly to your computer with a USB cable (avoid USB hubs and
dongles),
power up the Tracker,
in the Polyend Tool, choose the .ptf file you want to flash with,
use a pin to press the hidden Reset button next to the Tracker’s USB C port,
wait for the firmware update to complete,
if it’s at 100% but the device didn’t reboot on its own, do it manually,
re-insert the SD card to the Tracker’s slot,
important:
Unit is still crashing? Try this: connect your SD card to your computer and delete
the hidden “Workspace” folder.
