There is the R-8_tda_Asy_P_dop1.1 fw that can be flashed, after that there is the 2021 version, but you need the 2021 upgrade to flash it. If your r27 was upgraded to the 2021 version, then you have the latest (see http://www.audio-gd.com/Firmwaredownload.htm). The issue as you said could be caused be the singxer.
