Some ZGW's are more problematic to flash over ENET than others, FYI, here's my verified procedure for flashing ZGW with ENET which works for at least my 09/11 ZGW.

1. Assign 192.168.0.1 as static IP to the laptop's NIC
2. Run tftpd DHCP's server. In settings: pool starts at 192.168.0.2, pool size 1, default gw 192.168.0.1, subnet mask 255.255.0.0. Do NOT close tftpd
3. Connect laptop with ENET <-> OBD2 cable
4. Make sure that the car gets 192.168.0.2 as assigned IP <- this allows swDeploy to finalise OK.
5. Start e-sys, connect via GW use 192.168.0.2:6801 as connection traget, select correct series
6. TAL processing - select the already calculated TAL and SVT target, in ECUs unselect everything except for swDeploy for ZGW
7. Go to parameters uncheck activate programming mode setting <- this allows post-flash ops to complete OK
8. Check software compatibility, press start
9. Remember to check activate programming mode for then next flash

Hi Breach,
1-> What do you mean by assign static IP? is it from PC network settings? and what about subnet mask and default getway there? 
2-> is all changes you mentioned in point 2 are in tftpd DHCP? becase I assume is default gw is the same is default router. subnet mask same as Mask (opt1)? or the default gw and subnet mask are in the network adapter settings? 

I'm trying to update my ZGW for updating th IHKA.

Hello, what is your ICOM configuration ?

I use enet cable.
