    Di2 - Is there a device order to firmware updates?

    Just got a Ultegra Di2 bike and have been researching a bit. There are some scary stories of bricking or temporarily bricking the system when performing firmware updates.

    I know it's not advisable to perform any firmware update via wireless using the wireless module (EW-WU111) and plan on using the PC E-Tube application.

    Is there a preferred order of devices for updating the firmware. For example should I update the battery 1st or last? Or just pull the trigger on all devices at the same time?

    -Thanks

    Can't help you with the order question but an additional question, does the Di2 system work with Mac computers yet??

    I don't think so. Currently the Shimano website only shows links for Android, iOS, and Windows. Of course within the next year once Apple moves their computers to ARM processors and everything is basically iOS, I don't see why it wouldn't work. At least wireless via the EW-WU111 module (firmware updating caveat would still hold I would assume).

    Plug into the PCE and it will let you know what needs updating (yellow box around component) and then show you a list that you can pick from. I always do 'update all' and let 'er rip. I'm at a shop so we don't bother w/ wireless, we plug in.

    Thanks. It came with the SM-BCR2 for charging and connecting to the system. As far as I have researched, that won't fix the battery if it bricks since it only connects to the junction box and not directly to the battery which the PCE can. The number of reports of firmware update issues is pretty alarming when you research it. The issue right now locally, all the local bike shops are backed up for 2 weeks or more for service and may not be able to try to fix the battery if things go south. That's assuming they have the PCE troubleshooter. I'd rather not to get in a situation where I would need to purchase one if I can help it. I'll hold off until I get the EW-WU111 wireless module at the soonest and then let 'er rip in one go. Thanks again.

    I have heard lots of problems with firmware updates using the wireless and none using the charger and Shimano etube software. I would never try to update wirelessly. I have 3 bikes with Di2 and have not had any issues with a PC/charger and the Etube software.

    The only real time wireless firmware updates really bug-out in a dependable manner--are firmware updates to the Di2 wireless module. Everything else is 99% of the time fine.

    Thansk. That is good to hear everyone. It is re-assuring to hear. I wasn't planning on updating anything wireless as that seems to be the majority of the issues.

    I haven't tried in a while, but the last time I updated firmware on my iPad, it updated everything except the wireless unit, and told me I had to do that via the PC software.

    Find by me, the interface on the wireless software is crap anyway. The UI on the windows software isn't anything to write home about either, but at least it's relatively easy to understand whats going on (once you've used it a few times). It's also 100% reliable for firmware updates.
