First I installed @ronnz98’s build e-1.15-s-20230919-UNOFFICIAL-herolte_by_ronnz98.zip with e-Recovery, and from there I manually updated to new @ronnz98 build e-1.16.1-t-20231028-UNOFFICIAL-herolte_by_ronnz98.zip, which worked fine.
Since the e-Recovery allows the manual update via adb sideload from the microSD card, i.e. without an additional PC, the update is as easy as an OTA update.
@ronnz98, all system apps, including Battery + Display + Notifications + Sound & vibration as well as Fingerprint (home button) work flawlessly 
@ronnz98, you are great. Thank you very much.

Very advantageous for future @ronnz98’s updates:
Updating can be done without a PC, as the e-recovery allows ‘adb sideload’ from the microSD card.
