Firmware for the Epson PowerLite X36+ projector, main board H721MA revision R1A, version V204, packed in a 288 KB RAR archive. Projector firmware of this kind is used to recover a unit that stalls at startup or after a failed update, either via the service update procedure or by writing the flash chip with a programmer. Confirm the board code on your unit matches H721MA, keep a copy of the existing firmware, and check the image size against the flash chip before writing.
