Notes on USB flash drive compatibility:
Please note: for ovens with firmware 3.1.0 and older installed, use of certain
types of USB flash drives may result in issues when attempting to update to
newer firmware. ACP recommends using a USB flash drive with MLC-type flash
memory. Recommended flash drives include:. Transcend JetFlash 600-series USB
flash drives (TS4GJF600, TS8GJF600, TS16GJF600, TS32GJF600, and TS64GJF600).
Once the firmware has been successfully updated beyond version 3.1.0, any USB
flash memory type (SLC, MLC, or TLC) will work for future updates. If you
encounter difficulty loading firmware, contact the service and we can send you
a known good flash drive to use for updating the firmware.
