Original NBT navigation blocked in flash mode

[avatar2100]

Hello everyone, a few days ago, without knowing exactly what I was doing, I performed a car update using ISTA+ 4.15.16. After these programming steps, the HU-H module wasn’t programmed correctly, and the NBT navigation (large, original) remained with a blue screen. I tried to redo the update twice, but each time, the result was the same.
I would be grateful if you could help me fix this issue. I’m attaching pictures of the car's errors.

Thank you.

Use a newer ista if you have to use ista to update the headunit. Set up BMW ICOM DHCP server before the update. Preferably try to update with esys and enet cable. You can easily find instructions with a Google search.
