Hi Bro,
I was browsing this forum and found a reference to you :-)
From what I see on the web, you're probably only one person who could help me ... I hope :-). I am looking for firmware e-tube_proj_v_2_3_0.exe, and your earlier answer indicates that you had something like this. Hence my question -do you still have this firmware? And could you share with me of course :-).
Thank you and best regards,

I think RD6870 firmware files have different filenames
I will send you more info in pm (this is offtopic)

I can't answer you on your pm cause i'm fresh here:-). So i try to fix to cross Di2 hardware based on the 6700 series components with the rear derailleur RD 6870. I downgraded the software in all components on 2.5.2 firmware, unfortunately I can't do it on RD 6870 and now only front derailleur works :-(.However, I have heard that the firmware e tube 2.3.0 or soft for RD6870 called rd6870.2.5.0.dat can help. Hmm

Can anybody help me out.

I have a fairly early 6770 groupset. I would like to swap out the shifters and use ST-R785 shifters instead to get hydro brakes, but still keep it 10spd.
I would probably need to update the software, but to a certain version. What are the thing I need for that?

Can I use SM-BCR2 to update the software or do I need the older SM-PCE1?
I assume the old firmware versions are not publicly available from Shimano?

If you mount the ST-RS785 with the rear derailleur 6770 you will follow with 10 speed, you will need to update the firmware of the battery support to recognize the levers.....If you have the juction EW67, you have to use the SM-PCE1.....with the EW90 or RS910, you can use the BCR2 or SM-PCE1
