i can rewrite the build info in FW to report as new while it will be an older version .. for example FW 1.0.3.22 will report as 1.0.4.9 .. but you will lose the possibility of OEM update. but via notify and GadgetBridge should go upload.
when i had version 1.0.1.32 it worked normally .. since updating to 1.0.1.36 it does nonsense the first 10 minutes of walking .. otherwise it matches the omron pressure metter + -2 pulse.it occurs to me that after the update the green light is less lit (improved battery life?)
