Had Di2 for 2 weeks now, expensive but worth it, absolutely loving it so far. Your videos about the wireless module (which I don’t have.......yet) & synchro shift etc have been invaluable. Keep up the good work Shane 👍🏻

[@PaulGM]

I had a similar problem with a failed firmware update on a newly installed wireless unit. Cold sweat time. Unplugging & reconnecting the front and rear derailleurs got them recognised again and all was well. Would have been so much less stress if this video has been out there! Well done Shane 👍

[@BetterShifting]

BAM. There it is! Good to see the mobile app could restore the RD 🎉

[@gplama]

It was a surprise! I was all set to pull out the charger, then the PC Link.... Looks like the mobile app is a little more functional than I gave it credit for.

1:40 imagine being in need to buy a "module" to update your gear. Brilliant video Shane. A couple of days ago I've fully disassembled my bike in less than 10 min to repaint the frameset, and it will take the same time to assemble it back. Happy days, thank you sram.

I hadn’t updated firmware in over a year...completely bricked with the phone. I had to plug it into the computer and do a complete restore. Got it working after an hour.

[@galenkehler]

I bricked my di2 initially using the newest version of the etube PC app, till I realized I had to use the older version. It's a smaller button on the etube page, and the app looks like windows 3.1, but it works :)

[@עופרקלימי-ה1פ]

Thanks you help me to solve this issue with my rear derailleur firmware you are the best!!!

[@geraldberliner5260]

So last night I bricked my entire Ultegra Di2 system when fitting the Blue Tooth Wireless EW-WU111 mobile unit. I had taken all precautions, had the phone close to the unit on a stand so I wouldn't move it, closed down all other apps on the phone, but overlooked one. more. step. and that was to turn on 'Do Not Disturb' on the phone. Sure enough, half way through the firmware update on the WU111, a notification from my Amazon app popped up saying a delivery was on the way and sure enough, that was enough for it to interrupt the update and my whole Ultegra Di2 shifting was left dead in the water. Nada. So my only course of action was to use the Di2 Charger - SM-BCR2 - to connect to a PC and update everything via the E-Tube laptop/desktop app. The only problem is I don't have a PC and am only on a mac, which Shimano, god knows why, do not provide a Mac version for, only the flaky iPhone and iPad app which were going to be of no use to me to whatsoever to restore the Di2 system. My workaround was to virtually install windows 10 on my mac using VirtualBox, installing windows 10 and downloading the E-Tube app. I believe this is a route you went down in another video you posted, except you didn't go into any real detail about how to configure VirtyalBox with Windows 10 to achieve this. I found another video that did: kzbin.info/www/bejne/nqasfHetmbdorNk It totally worked and I was able to reboot my Di2 system and do all the necessary component firmware updates. As an FYI the E-Tube V.4 app will only work on this set up, not the latest v.5 version.This totally saved my butt, and an extremely long (and expensive) journey to a bike shop that was capable of doing this for me. Many thanks for all your hard work and effort in putting these vids together, they are extremely useful.

[@shanew634]

Top tips Shane.👍

[@aussz]

Just a note for those who have bricked their wireless unit: you may need to disconnect your battery for a minute before being able to reflash the firmware from your PC. Otherwise, you will experience an endless loop of failed connections.

[@adammcintosh8556]

Hi Shane. Great vid. I luv Di2 right down to its chirping noises and the slightly different chirp it gives for the last change before synchro gives you the big chainring. I see you have the Varia mount there..my second favourite thing..

[@NathanLipkeEvilN8]

You haven’t lived until you crashes the EW-WU111 upgrade. For reference you can restore with your phone. 1. Pull your seat post and disconnect the battery. 2. Disconnect the EW-WU111 3. Plug the EW-WU111 into the battery. You may need to disconnect a cable from a shifter to do this. It will reset to some base version and will allow you to re upgrade your firmware.

[@rosscads]

I have been there, and thanks for the remedy. Unfortunately for me my wireless module and battery are in the bottom bracket so not easily accessible. 😭

[@patrickrenschler]

Is it possible to successfully update the EW-WU111 over wireless connection to the phone app? Or do you have to do it with the computer cable? I just tried updating via mobile app and it crashed. Thanks for posting this recovery process, will see if I can bring it back to life.

[@NathanLipkeEvilN8]

@@patrickrenschler it eventually worked. Took a few tries though. Cable/computer is probably better.

[@patrickrenschler]

@@NathanLipkeEvilN8 You saved me not sure what I would have done because I don't have a PC. But yes it was a slog haha! It took me multiple attempts and ~ 30 min. Finally got it to work. Ended up disconnecting all cables, forcing the iPhone to forget the BLE connection with the wireless unit, letting things rest for several minutes, plugging the battery into the wireless unit directly and letting things rest for a few minutes, and then plugging everything back together and reconnecting with the app. Once reconnected, the app failed to restore the firmware a few times and I had to repeat the process.

Mine failed a firmware update and could not restore it wirelessly. Ended up having to use the wired route with the charger to the A-junction box. No issues with that.

[@quasijones]

I had issues using the app on iPhone and ended up with a partial update and non-functioning (and new) system that kept failing to restore. Was about to send the battery back to supplier and as a last check tried using my IPad instead. It worked perfectly first time and consistently ever since. Exactly the same app version, I can only assume it’s that the Ipad has different bluetooth chipset,

yep, had exactly this issue a couple of times in the past. It is a lot better now I've found with later version of app, the problem used to be that the connection was useless.

I now have the PC link box and have fixed it myself using windows laptop (grrr as I have Apple, please bring out Apple version!)

[@keithburton99]

You are lucky. I have just been told by Madison ( UK Shimano distributor ) that my Di2 display SC-MT800 is corrupted and cannot be recovered. It will be replaced under warranty but , of course , they are out of stock and it will take 4 weeks to get a replacement.

[@gplama]

Do you still have access to it? It’d be a good chance to see if it can be revived with the PC linkage device (if you can get your hands on one).

[@keithburton99]

It cannot be recovered by any means including the SM-PCE02 PC linkage by me , the bike shop or the UK distributor. It still functions as a display but cannot be updated. It stops any of the E-Tube apps from connecting to the bike because they insist on trying ( and failing ) to update / recover it.

[@gplama]

Damn, that's really screwed!

[@paulschectman6586]

Do you feel that it is worth the expense and work to upgrade from my SM-EW90-A under stem junction box to a new Blue Tooth EW-WU111, E-Tube Port X2 in my drop bar? I would need to remove the new $$$ bar tape that I just installed, plus install the Shimano E-Tube Di2 Y-Split Rooting - EW-JC130. This sounds like a lot of work with wiring... The convenience of using a phone update and gearing options is compelling if it works well and integrates with my Garmin Edge 830 like you show in the video. I have a Mac computer so I can't do updates at home, and I need to take to a bike shop to do Di2 updates and custom gearing...

[@gplama]

It depends. It'll tidy things up for sure. If you want to tinker with your bike with the goal of making things a little neater, go for it. 👌🏼

[@davidstihler9689]

Thank you, I wonder if you could show how to get DI2 out of crash mode which the system will go into if you impact something like the rear derailleur hitting something and knocking it out of alignment. Crash mode means the system is totally usable until you go through a sequence

[@anderssundberg9490]

Is it "safe" to just connect via bluetooth, the smartphone and head unit? Not doing any firmware update. Instead using di2 charger and a pc for firmware update.

[@KrisCoetzee]

A question for you Shane (or any subscribers really) - The bluetooth unit obviously uses battery to connect whilst being in use. I am only using to it manage the Di2 and not pair it to my Edge head unit. Should I be unpairing the unit from my phone after every use to lengthen the battery life if the Di2, or does it only use DI2 battery charge whilst paired and in use with a device (head unit or phone)?

[@gplama]

It only pairs to your phone when you put it in connection/management mode (short press of junction A button).

[@xaviervanhoorebeke2292]

I ran a firmware update on the Bluetooth module and it got bricked. Connecting using the pc link that came with the di2 did not solve it. After a visit at the LBS we ended up in replacing the Bluetooth module. A little scary and not funny after 1 week with the new bike with a dead shifting system

[@ECTproCycling]

A few simple flights to and from races seems to destroy Di2 (usually half way through stage 1 or 2 oddly enough) from our observation of others.

[@jcerullo5015]

shifter buttons are getting pressed in the box.

[@ECTproCycling]

@@jcerullo5015 Nope. Cables are being half pulled out inside the shifters or the frame. Buttons being pushed would be a simple battery charge issue.

[@ianrichardson8657]

[@sirledge]

You can kill DI2 for good apparently - just flash your shifters as a front derailleur. Not even Shimano support could bring them back. Be careful using the more expensive pce01.
