Lost SD Card for your ST4 or ST4.3

All new Spectrum ST4 units include a microSD card, which is used to update the firmware of the unit with new fixes and features. Each card is configured and tested to work with your Spectrum. Check out this article for full instructions on updating your firmware, and a list of fixes and improvements with each firmware version.

What to do if You Lose Your MicroSD Card

We recommend using the included card to update your firmware. If you lose the card, it is possible to use your own. Follow the instructions below to configure the card to work with your Spectrum.

1. Using any class 4 or better (speed) microSD card that is 32GB or smaller.  
2. Use an SD adapter to connect the card to your computer, and open your device manager (Windows) or disk utility (Mac). Format the card as 'Fat32' (On newer computers, this may appear as MSDOS-FAT, in the format menu).
3. Under the card root directory, create a folder named 'update' (all lowercase).  Place the firmware file in the update folder.  The path of the firmware should be root/update/XXXX.srec
4. We also recommend you, add a "tape tail" to any card you put into the spectrum to make fishing it out easier!
