Gigapan Epic Pro Firmware Update Problems and Solution (Updated November, 2025)

Gigapan has a firmware update available for the GigaPan Epic Pro, here: GigaPan Epic Pro Firmware Update

To find out if you need it, check the firmware on your Epic Pro thus:

Select “Options” – “Expert Options” – “Firmware Version”
The current firmware version is P010100171-8.

Download both the installer and the firmware from THE GigaPan website. Note that GigaPan as a company is gone, but the download pages on their website are working as of November, 2025.

The following steps were tested on Windows 7 and Windows 10; I have not tested them on Windows 11.

I have a couple of very important tips for Windows users (Windows 7, specifically) which will help prevent any disasters from occurring (i.e., a botched firmware upgrade which will result in a dead Epic Pro):

1) Install the Firmware Upload Tool “As an Administrator”
2) Connect the USB cable from the Epic Pro directly to the motherboard, not to a hub or to the front panel USB ports on your PC. Connecting through a hub caused my Epic Pro to lockup and not be recognized by Windows.
3) Run the Firmware Upload Tool “As an Administrator”

Battery Packs

There is also the issue of batteries.  The Epic Pro used a customized, rechargeable, 7.2v NiMH battery pack. After long storage, the EPIC Pro charger will not charge the pack because the battery terminal voltage is too low.  Therefore the packs need to be charged using a voltage and current limited power supply. This is typically called a “Lab” power supply. The idea is to “wake up” the pack slowly, and then run it through the charge/discharge cycle several times.  Failing that, packs can be rebuilt using new cells.
