3.1.32
February 10, 2026
Added connectivity and user manual for Maxi strobe (FW1.0). Firmware Update for Pro Max II (FW 4.0): - This update adds the Pilot Light Toggle (PLT) function. Activate PLT by holding the pilot/test button for 5 seconds while in HSS mode. Once activated, PLT works in all modes where the pilot light can be used. Moving the power dial one step up and down within 1 second simulates a press of the pilot/test button, allowing you to adjust the pilot light or turn it off. You can also turn off the pilot light in any mode by moving the dial one step down and up. Firmware Update for Retra Flash Pro Max (v2.17 - two.seventeen), Prime+ (v2.4), and Pure (v2.4). This update includes important bug fixes and performance improvements, such as: - Enhanced empty battery detection and indication, reducing false warnings. - New trigger recalibration function: In case of misfires, go to TTL mode, hold the pilot/test button for 6 seconds to start recalibration (indicated by "CAL"). The strobe will emit 5-10 high-intensity flashes to complete the process. - Improved pilot light stability when using 8xAA batteries, reducing flickering. - Additional updates to improve overall reliability and robustness. This App also includes firmware 4.2 (renamed 3.13) for Pro X/Prime X (3rd Gen) and firmware 4.5 (renamed 4.3) for PRO/Prime (2nd Gen).
