August 20, 2025Aug 20 Dear Community, I own two Airliner1 / AirLeaderX CDUs for FSX iFly 737NG. Both units are stuck in bootloader/ISP mode and require a firmware reflash. The updater (mcuisp.exe) works, but the firmware file is missing. Could anyone please provide the CDU_Update_20140415.hex firmware (the file referenced in the updater config)? Thank you in advance - without it the units remain unusable.
