Here are some tips aimed to help reflash BMW F series ZGM with E-sys v3.22.5 coding software.

to reflash BMW ZGM for F series

BMW ENET(OBDII toEthernet) cable?

BMW ICOM A2 emulator?

–> tools discussion quoted from a bmw forum:

SanDiegoF12: Why is an BMW ICOM A2 required instead of just using the OBDII toEthernet cable?

erdengurcan: ICOM A2more stable than enet cable. For example: When you update ZGW via ENET, sometimes car stays on transport mode. But via ICOM it always come back to normal mode.

2real4u: A more technical reason is lack of DHCP server when connecting with ENET interface. This does not affect connection over DCAN, which is supported by BMW ICOM, but cannot be accomplished withENET cable.

 

Working BMW E-sys v3.22.5 and psdzdata v49.4:

Error message when fail to flash ZGM:
Code:
MCDDiagService id=240900, job=com.bmw.psdz.jobs.common.MCD3_ActivateProgMode , service=RC_GAC – RoutineControl GetActualConfig, description=error: timeout, link=Physical request to ECU with address 0×10>

possible solutions:
*Use direct connection via gateway url instead of via vin to tcp://ip addressof your car:6801 eg tcp://169.254.30.100:6801
*In Tal Processing | Parameters uncheck "Switch gateway(s) to programming mode”

 

Hope this helps anyone.
