Hello Creality Team and Community,
I’m using a Falcon 2 Pro 40W laser engraver and I’m trying to update the firmware using the official file from Creality Cloud:
Firmware file: CV40-Pro-MASTER-Release_V1_0_38_202508121842.tar.gz
Source: Creality Laser Engraving Machine Firmware Download | Creality Firmwares
I extracted the laser.bin file and placed it in the root directory of the original SD card that came with the machine. The card is formatted to FAT32, and only the laser.bin file is present.
I inserted the SD card while the machine was powered off, then turned it on. Unfortunately, the machine does not respond — no LED flashing, no restart, and no indication that the firmware update has started.
I’ve verified the file name, format, and card capacity (32GB), and followed all recommended steps.
Device Serial Number: 50000022246222ESCDTN
Could you please confirm whether this firmware is compatible with my device, or if there’s a specific update method or intermediate version required before applying this one?
Thank you in advance for your support!
