Check or build a config.xml for ePaper USB Preset (EM13DX / EM32DX / EM32DX-A, FW 1120 / 1130.7). Runs entirely in your browser — nothing is uploaded.
Choose the firmware before you provision — the two official builds are not equivalent. Set the same version in the Firmware on the devices box above and the checker will judge your file against it.
1. Extract the .zip to the root of a FAT32 USB-C stick, keeping its folder structure — the files must land at \S-RSEDWWC\image\ (with upgrade.msd and info.txt inside), directly in the root, not nested.
2. With the device powered on, insert the stick into the USB-data port (USB icon, not the power-plug port). The update starts automatically when the stick holds a newer version.
3. Let it finish and reboot (a few minutes) — don't cut power or pull the stick mid-update. Then verify the version in the Samsung E-Paper app.
Not sure which options you need? The Samsung ePaper Configurator asks a few questions and hands you a deployment plan, an IT/network checklist, and a matching config.xml.
