Destroying Shimano Di2 Groupset Shifting with a PHONE // Di2 Firmware Recovery

While electronic groupsets have proven to be very robust in the field, they’re not immune to failures or issues on the more technical side of things. In this video I brick/destroy the Shimano Ultegra Di2 RD-8050 rear derailleur with nothing more than the Shimano E-Tube app…. and I go about restoring it back to working condition.

Note: Firmware restoration of individual components on non-working Di2 system will require the use of the PC Linkage Device (SM-PCE1 or SM-PCE2).

  1. Just got a new Di2 group. The shift buttons are around the reverse way for my liking. So do I need the D-Fly unit to be able to talk to the group with the E-tube app and swap them? Or can it be done manually? So lost.

  2. Use the charger to connect to the bike (via Junction A) and plug the USB end into a Windows PC. With the Shimano E-Tube app you can perform any reassignments you like.
