And are you using the EW-RS910 and EW-WU111?

No, I have the earlier D-Fly, the 101 and the older 3 port junction box mounted under the stem.

I guess the smarts are in the battery. You'd think Shimano would have made firmware updating by consumer to be more fault tolerant, and that if for some reason it had a problem, it would roll back to previous working state.

All steps:
1. Downloaded E-TUBE to PC
2. Connected Di2 on SM-EW90 with SM-BCR-2
3. Open E-tube and got both flushing light on SM-EW90
4. Updated the software-just follow the steps.
5. Open E-TUBE on iPAD and connected with Di2 Wireless Unit EW-WU111 D-Fly ( installed on bike)
6. Updated all Di2 components.
7. All done ! Di2 9150 system working perfect.

Thanks for all replies.
Alek this list saved me a bunch of trouble. My battery was bricked from a failed blue tooth update from my IPhone. I was using the new EW-RS910 bar end junction with the EW-WU111. So at your step two I was attempting to fix the firmware using my SM- PCE1 to connect to the PC based E-TUBE software. It’s only when I read your post a third time I noticed you made the connection using your SM-BCR2 which I have but only use for charging. In step 3 I don’t think my EW-RS910 ever went into red/green flashing mode. Using the E-TUBE on my PC I was able to update all the firmware except the EW-WU111 and got a message it needed to be updated but must be done using ETube on IPhone/IPad. Bummer but by now, my battery was no longer dead and I could get the flashing lights again on the EW-RS910 and connect to my phone and update. Whew! I had already tried to contact the online shop where I bought the battery and ask for a warranty return. Haven’t heard back from them yet but now I’m ready to go. Oh, yea. Since I thought my battery was cooked, I pulled it out of the down tube mounting spot on my Cervello S5. Now I get to put it back in. Pain. Thanks. Hope this helps someone.

Only issue is that the Shimano software is for PC. Not sure if it works on a PC emulator on a Mac.
