Hi. I did a firmware update check on the Next Gen app for my 2020 SR/S and yes, there was an update available for the MBB V23. I started the process and everything went smoothly and the firmware loaded up until the end (progress bar fully completed). I heard a click in the bike and then nothing for a long time (closed to 30 minutes.) I decided to turn the key OFF and it did nothing.. stayed ON!!. Turned the key On and OFF, no response, The display is frozen and I do not hear the contactor. Disconnected the 12 v Battery, the display turned OFF but as soon I reconnect the battery, the display turned ON with SOC to 0% ( it was at 58% when I started the update). Again, nothing happens if I turn the key ON.
Is this a case for a service call or is there something I can do to reset to normal?
Thanks in advance

I had a similar behavior when i installed v19, where the SoC went from 90% or so to 0% after the update. I turned off the bike and let it sit for a while (couple of hours or so)., then the SoC came back up to the expected number.
However, I did not have the other issues you mentioned here. But if your bike remains in this state, I would suggest contacting a dealer.
-
Oh BTW, the odometer has returned to 0, yes 0 km. Like a brand new bike. The display is still ON (unless I disconnect the 12v battery) and the key on-off does nothing. Is this bike bricked?? I am totally confused.
-
Still under warranty I hope?
-
pargil,
My bike had exactly the symptoms you described after I took it out of winter storage. The MBB had to be replaced and the odometer had to be reset by the dealer.

When you say the odometer had to be reset by the dealer, you mean to the last reading or 0? I am still wondering why a simple firmware update would render the MBB useless. The bike was running perfectly well before. Maybe, I should have resisted starting the update. All perequisites were met and I never suspected this kind of result. Over the winter, I did the upgrade from V19 to V21 without any problems. The bike is still under warranty but I am afraid it will take some time before it is fixed. My dealer is 260Km away, so a trip with the trailer is required....arrrh.
I appreciate all your inputs or ideas.

After over 20 attempts my bike finally updated from v20 to v23. I'm glad to say it seemed to go OK - apart from the reapperance of Canyon mode of course. (Whoever wrote the Zero app shoudl be thrown into a canyon if they love them so much.)
I hope Zero fixes your bike quickly.

pargil,
After the MBB was replaced, my dealer had to reset the odometer to its last known value (my best recollection). Prior to the MBB replacement I had all zeros on the dash (SOC, Range, ODO, Trip Meter).

What you described is exactly what I have. Can you tell me if the repair took a long time? Was the MBB board quickly delivered to the dealer from Zero?
Thanks

Swapping the MBB was relatively easy; the time consuming part was removing and reinstalling all the bodywork. It took a few days to diagnose the problem since my dealer had to get on the phone and work with Zero's technicians. Once the MBB was found faulty, Zero got the replacement to my dealer within a day or two.

Really? I was checking something yesterday and took the "tank" off as one unit - six screws and 5 minutes. The MBB was just sitting there attached to the right side of the storage bin. The wiring was easily accessible too.

I have an SR/S.
-
For those of you having problems completing the update, are you attempting the update using the phone app or are you trying to do an over-the-air update after receiving a message on the dash that an update is available? I never got a dash notification and, like many of you, tried multiple times using the phone app before the update was successful.
-
I did not receive notifications on the dash. Only after checked the firmware update menu in the app, that I proceeded with the update over wifi with the very bad outcome that I described earler in this thread. BTW, I have an appointment with my dealer next Thursday and I will keep you posted on the diagnostics. Current state is the dash can only be shut-off if I disconnect the 12v battery with all readings reset to 0. Turning the key on and off does nothing. MBB seems to be completely dead or software corrupted.
-
the update worked on my srs 2021
but I didn't notice any difference.
Unfortunately, I still have my 3G connection problem.

Cross posting from FB. Try this it seems to have worked for some folks:
. Install firmware update on bike
2. Pair the bike over Bluetooth to the app
2. Create a new custom mode
3.. Adjust some settings while the mode is inactive
4. Activate the new custom mode
These steps will invoke the MBB to pull up the correct ride mode settings and should fix issues with power, torque and top speed on SPORT mode.

I am analyzing my options as to what reasons my bike (SR/S) got bricked following a firmware update (V23). Actually, turning the key ON-OFF does nothing. The display is frozen and no bluetooth link is possible. I can only turn Off the display by disconnecting the 12v battery, Do you think a BMS reset (board behind the front wheel) would bring the bike back to life? I can't imagine having to replace any components following a simple software update...The bike was running perfectly well before.

hello
same issue for me on my SRF with last firmware (21) : the bike was a brick.
I shoud bring it to the dealer ... he connect its computer to the obd port in the tank, and send the firmware in 5 minutes ...
no need to change MBB board, juste install firmware with OBD connection and their computer
-
I just spent some time in the garage trying to upgrade from V21 to V23. Three attempts, three failures. Apparently the bluetooth connection between the phone and the bike is working, yet the data transfer fails at random stages and the bike tells me to key it off for three minutes and try again.
I've seen alpha software do a better job. How can't they even get a simple data upload right?

It sure is strange that Zero managed to finally get the Gen 2 software updates working perfectly, with no more failure messages and similar issues, but now are having even more problems with the Gen 3 bike updates. Why reinvent the wheel once you finally get it round and then start off again with a square shape? I just don't get it. ???

Thanks Morpheus74
I am crossing my fingers that it is only a matter of uploading again the firmware with the computer hooked to the OBDII port. I have an appointment with the dealer this Thursday. I will keep you posted of the results.
-
Sorry to hear about your bad experience. I guess I am lucky in this case: A couple of days ago I upgraded to MBB V23 through the "Zero Next Gen" android app using bluetooth. It took about 35 minutes and ended with the creation of the CANYON mode, which suggested me that it went ok.
I cannot yet tell if the torque went back up to what it was when I bought the SR/F; for that I think I will to ride with a passenger. The probable loss of torque resulting from an update to MBB V21 I did in March at my Zero dealer was my main motivation to install that firmware update. I can confirm that the "Remote Connect" function (cellular & GPS) is still working fine over the internet.

I've just experienced a similar problem to yours today - unfortunately the dealer I bought my bike from is no more and my nearest is more than 60 miles away! I disconnected the 12v LiIon to power cycle the MBB but to no avail so I removed the bodywork (6 screws - 5 minutes) disconnected the 12v and unplugged the two MBB connectors, left it for 30 mins and then put it all back together. Hey presto! All running again albeit with V21 but will try again tomorrow but this time with a charger connected to the 12v battery (deffo recommended)
Update - couldn't be bothered to wait another 24hrs so connected a charger to the 12v battery (in case it takes several hours of repetitious update failures) and continued the update process. After dozens of attempts I've finally managed to update to V23!! I'm just guessing here but I seem to have more success with the phone approximately 2 metres away from the bike (not too close for better BT connection) and WiFi switched off on the phone, just using cellular outside the garage.
Time to find out what changes (if any) after a good nights sleep :)

I am back from the dealer in Montreal area with a bike fully functionnal. Thanks to the expertise of the technical staff, he was able to restart the MBB, reset the BMS and load the latest V23 firmware. I still don't have an answer as to why the firmware upgrade I did myself turned out to be a total failure. I did myself the upgrade from V19 to V21 without any problems. Lessons learned, I will now book an appointment with my dealer for every future firmware upgrade. Furthermore, those upgrades are free of charge for the life of your bike according to a recent note from Zero. I am not saying, don't do it yourself, but if you are at a reasonnable distance from a dealer, I think that it is the best option.

If you wouldn't mind maybe some pictures of which screws you needed to remove to get access. Started to try and dig into this since I'm having the same issue and don't feel comfortable knowing which things to take off.

So I had the same problem with the bike not rebooting during the upgrade. My dash remained on no matter what I did with the key.
As said in the post above, disconnecting the 12v battery turns off the dash but as soon as you reconnect, you have the same problem. The post above had the solution. Remove the tank and you will find the MBB mounted on the left side of the storage box. Pull the 2 connectors and leave them off for a while. When you reconnect them and the 12v battery, the bike reboots as normal and dash stays off.
