    Charge Di-2 Ultegra Battery dead

    These are the steps which I followed and this is current situation:

    • My battery was running low
    • I plugged it for charging
    • In the meantime; I connected the system via Bluetooth through E-tube app on IPhone.
    • It showed 3 firmware to be updated Battery, RD & Shifter
    • It successfully upgraded the RD & Shifter
    • While upgrading the firmware for Battery; the battery died and hence the firmware upgrade was not successful.
    • Now the whole system is dead. When I plug in; there is no battery charging which is also happening.


    I looked at postings and looks like the only way for me would be to upgrade the firmware through PC?

    I have been always upgrading it through E-tube App. I have couple of questions and if somebody could help me; it would be great:

    • The battery is dead. How do I charge it?
    • what hardware I need to connect it from PC? Do i need to buy only SM-PCE1 or there are some other connectors which i need to buy along with the above.

    You either need to use the PCE1 or take it to a shop that has one and have them help you out.

    There is another thread on this site where someone went through the same issue as you. That poster has detailed instructions in their thread.
