The problem with lan can be solved by replacing the micrel.
Check all the lines from lan to micrel and if it's okay then change micrel

RE: BMW Icom A2 repair
Need help. My ICOM A2 Spansion NOR Flash is damaged. i tried to replace it and use the restore from usb doesn't work. It just blinks red once. Put the old one back and then it fails to boot. Jut blinks green. How do i load the firmware on a new NOR flash, Which programmer to use and how. Can i make backup from the old NOR flash from the ICOM? I saw people use teensy 2.0 ++ to make a dump and restore. Will it work? Because the PS3 also comes with Spansion but 128mb chip, Icom has a 64mb chip.
Please advise.

Spansion Flash must be programmed before soldering and then restore ICOM.

RE: BMW Icom A2 repair
Thanks a lot Ferrum. Which programmer do you recommend to do this job? Will teensy 2.0 ++ work?

RE: BMW Icom A2 repair
I use the programmers ChipProg-481 and Triton sold in Russia.
I think you can use any programmer supporting S29GL064N90TF102

Hello ferrum,
I change micrel on my ICOM and the problem is always there.
LAN led never blink, and ICOM not visible in Ethernet connection.
It boots correctly, SYSTEM LED blink and then stays ON.
Can you help me, please ?
Thank you
Bests

RE: BMW Icom A2 repair
Did you change the Samsung NAND?
Change it and restore firmware.
Should work as spomeone has reported the same issue as you and it worked after that.
