Wow, da versteh ich nicht, warum der FD6770 noch "so teuer" angeboten wird...

INCLUDED FOR VERY MOTIVATED INDIVIDUALS ONLY: 10-SPEED FRONT DERAILLEURS CAN BE USED WITH 11-SPEED REAR DERAILLEURS IF THE SHIFTERS AND BATTERY HAVE FIRMWARE INSTALLED FROM E-TUBE SOFTWARE VERSION 2.5.2 OR EARLIER. SHIMANO DISABLED SUPPORT FOR THIS 11-SPEED AND 10-SPEED CROSS-MATCHING WITH LATER FIRMWARE UPDATES. FOR INFORMATIONAL PURPOSES ONLY, THE DETAILS OF HOW TO REGAIN COMPATIBILITY ARE DETAILED BELOW.

IMPORTANT NOTICE 2014-07-14: THERE IS A COMPATIBILITY ISSUE WITH SHIMANO E-TUBE SOFTWARE/FIRMWARE VERSIONS V2.6.0 AND LATER THAT PREVENTS 10-SPEED FRONT DERAILLEURS (FD-6770) FROM WORKING WITH 11-SPEED REAR DERAILLEURS (RD-6870) AND 11-SPEED FRONT DERAILLEURS (FD-6870) FROM WORKING WITH 10-SPEED REAR DERAILLEURS (RD-6770). DO NOT UPDATE FIRMWARE USING SHIMANO E-TUBE SOFTWARE V2.6.0 OR LATER IF YOU ARE MIXING AN FD-6770 FRONT DERAILLEUR AND A RD-6870 11-SPEED REAR DERAILLEUR, OR A FD-6870 WITH A RD-6770.
THE PROBLEM COMPONENT IS THE BATTERY (EXTERNAL BATTERY MOUNTS SM-BMR1 AND SM-BMR2, INTERNAL SEAT POST BATTERY SM-BTR2.) IF YOU KEEP BATTERY FIRMWARE AT V2.0.6 OR EARLIER, THE SYSTEM WILL CONTINUE FUNCTION PROPERLY. SHIMANO E-TUBE SOFTWARE V2.6.0 WILL UPDATE BATTERY FIRMWARE TO V3.0.5, AND WILL NOT ALLOW THE RD-6870 TO WORK WITH A FD-6770 SETUP.
IF THE BATTERY FIRMWARE IS UPDATED TO 3.0.5, IT CAN NOT BE REWRITTEN BACK TO THE OLDER VERSION. YOU WILL NEED TO NEED TO REPLACE A DERAILLEUR SO THAT BOTH ARE 6770 10-SPEED OR SO THAT THAT BOTH ARE 6870 11-SPEED. (THE OTHER OPTION IS TO GET GET A BATTERY WITH THE OLDER FIRMWARE AND NEVER UPDATE IT.)
HERE’S A LINK TO THE “LAST KNOWN GOOD VERSION” OF THE SHIMANO E-TUBE SOFTWARE TO WORK WITH A MIXED 10-SPEED/11-SPEED SYSTEM: E-TUBE_PROJ_V_2_5_2.ZIP USE THIS VERSION AND DO NOT CONNECT TO THE INTERNET WHEN USING IT SO THAT E-TUBE CAN’T CHECK FOR UPDATES WHEN OPEN.
TO ROLL-BACK NEWER VERSIONS OF BATTERY AND SHIFTER FIRMWARE, INSTALL E-TUBE VERSION 2.5.2 AND MADE A COPY OF “C:\PROGRAMDATA\E-TUBE PROJECT\FW” WHICH HAS ALL THE FIRMWARES PACKAGED IN THAT VERSION OF E-TUBE. NEXT, INSTALL THE LATEST VERSION OF E-TUBE. THEN COPY ALL THE FIRMWARES FROM THE THE 2.2.3 VERSION BACK TO THE SAME LOCATION “C:\PROGRAMDATA\E-TUBE PROJECT\FW” FOR THE LATEST VERSION. NEXT, THE TRICK IS TO FIND THE FIRMWARE YOU WANT TO DOWNGRADE (PRETTY EASY FROM THE NAME AND VERSION IN THE FILE NAME), AND THEN RENAME IT TO THE SAME NAME AS THE LATEST VERSION, BUT INCREMENT THE LAST VERSION DIGIT BY ONE. THEN CONNECT TO THE BIKE WITH E-TUBE (WITHOUT AN INTERNET CONNECTION) AND IT WILL IDENTIFY THAT A FIRMWARE UPGRADE IS AVAILABLE FOR THAT COMPONENT AND ALLOW YOU TO DO THE FIRMWARE “UPGRADE” TO THE OLDER VERSION OF FIRMWARE. NOW EXIT E-TUBE AND THEN RENAME THE FIRMWARE FILE BACK TO ORIGINAL TO PREVENT ISSUE IN FUTURE. E-TUBE WILL THEN TRY TO UPGRADE AGAIN BUT JUST DON’T LET IT DO THAT. THIS SHOULD GET A BIKE THAT DID NOTHING (NOT EVEN ENTER ADJUSTMENT MODE) TO A FULLY WORKING STATE BY REVERTING THE BATTERY AND SHIFTERS. RUNNING LATEST FIRMWARE IN DERAILLEURS SEEMS TO BE FINE. (THANKS TO COMMENTER VOSADRAIN)
IT WILL NOT BE POSSIBLE TO CHARGE THE BTR2 INTERNAL BATTERY USING THE BCR2 USB CHARGER UNLESS YOU ALSO DOWNGRADE THE FIRMWARE OF THE BCR2 USB CHARGER AS WELL.
NOTE HOWEVER THAT LATEST E-TUBE SOFTWARE WILL SAY THE SETUP IS UNSUPPORTED AND WILL NOT ALLOW PROGRAMMING. TO DO PROGRAMMING, DISCONNECT THE INTERNAL BATTERY AND CONNECT A SPARE EXTERNAL BATTERY. THIS ALLOWS MAKING SETTINGS CHANGES. TO PROGRAM THE BTR2 ITSELF, I JUST CONNECT TO THE BTR2 BY ITSELF (NO OTHER COMPONENTS) AND THE E-TUBE SOFTWARE WILL ALLOW FIRMWARE CHANGES TO IT. OR TRY USING THE 2.5.2 VERSION OF E-TUBE.
ALTERNATIVELY, BUY A DI2DIY INTERNAL SEAT POST BATTERY KIT AND YOU WILL NOT HAVE TO GO THROUGH THE FIRMWARE DOWNGRADING. THE KIT MAKES IT POSSIBLE TO RUN ALL COMPONENTS WITH THE LATEST E-TUBE FIRMWARE. ALSO WORTH NOTING SOME FIRMWARE UPDATES WERE DONE TO FIX POWER DISTRIBUTION ERRORS IN THE FPGA’S THAT WOULD ALLOW THE BATTERIES TO DRAIN DOWN WHEN THE BIKE WAS JUST SITTING.
