There are two optional ways for you: one is using ISTA-D, another is by MSI Installer and Web interface.

First, install ISTA-D software on your system so you can use it to install the firmware on your ICOM.
Next, start ISTA-D with ICOM connected to your car (Don’t need KL15, KL30 13.8V on pin 16 and ground on 4+5 is enough)
Then, go to connection manager and start the update.

Here is feedback for your reference:
I test it this morning on a CIC of an E90 and an E60. And now also ICOM NEXT is flashing like HELL. So the bug of slow flashing CICR is gone with this upgrade. This I can confirm. THANK, it was long waiting but it was worth it.
