    Di2 Rear Derailleur 9070 protection mode

    I didn't crash just shifting hard on a step hill and it looks like my RD-9070 shifted all the way to the smallest cog and will not shift up again.
    RD dropped to the lowest position and stopped working. Just a bunch of clicking noises from there on.

    When I try to get out of crash mode it just clicks once or a couple of times but nothing happens.

    I think the clover pulley from the servo is positioned wrong from other pics of RD I have seen online.

    Has anyone run into this issue, should I force the pulley to move? Is that even possible?

    Do NOT force it.

    At a glance it look like your RD has literally lost a screw.

    I do not have a 9070 on hand to compare to...but none of my Ultegra Di2 RDs had a random threaded hole unfilled on the parallelgram....In red is what looks fishy and what I suspect.

    No matter what, don't force it, Di2 RDs are not made to be forced through their parallelogram motion.

    That hole without a screw is normal. The whole RD looks normal from that pic.
    Yes. I looked at my 9070 and compared.
