Funny thing is I had just sealed the board with the epoxy they sent. Waited the 72 hours and battery issue popped up after my second use. Everything was delivered around January/February and I used the snowblower module one time and it mostly worked okay but it was wet snow so I wasn’t expecting much. The unit wasn’t literally used again until last week when I sealed the board, attached lawnmower module, used it for about an hour and next day the B004 battery issue error and not recognizing any modules whatsoever. So, after about literally 2 hours or so of use I have a paperweight. 
You likely had one of the units that had the conformal coating with air bubbles in it. Did you use anything like water or alcohol to clean the board before applying the coating? If it wasn’t completely dry it could’ve shorted it out.
Nope. Used exactly what was recommended, only 91% isopropyl alcohol. It was actually fairly clean prior to the cleaning since I had only used it one other time for about an hour during the winter.

Cleaning that isn’t going to be much fun.

Leaf blower, vacuum and some cotton pads soaked in alcohol followed by some qtips for cleaning up the tougher spots.

So, just received a response from tech support. Apparently they did some diagnostics and found a “hardware issue” and I’ll be getting a replacement core. Not very happy that this happened to a brand new unit; however, I understand that sometimes these things can happen, especially with tech. I’m hopeful that the replacement unit will work just fine and they can figure out what happened to the old unit once they receive it and are able to do more in depth diagnostics.

At least someone got some good news today. At least I consider it good news.
At this point, I’m cautiously optimistic. They did mention it’d take 7-10 days for me to receive the replacement. I’ll post back when that happens and my results with the new unit.

There are a lot of cores bouncing back and forth. What do we suppose happens to the used broken ones that go back to the mothership?

I would speculate that they get “repaired” and shipped back out.

I’m totally expecting getting a refurbished one. I’m okay with that as long as it works and I don’t have to get another replacement.
For the sake of argument, as a new customer you’d be ok with returning a DOA core and receiving a refurbished one with let’s say 200 hours on the drivetrain and some new plastics applied? I have no idea if this is happening, just curious.
If you are within the 45 day replacement window you would get a brand new replacement and not a refurbished one. I don’t know if they are refurbishing yet, but I know they are analyzing the returned hardware and working on correcting any and all issues they identify.

I do t think anyone would be happy with that scenario. However, to be honest I understand that’s how the electronics hardware industry works. Majority of the time, any replacements to initial defective items you receive are always refurbished but obviously the warranties carry over. With that being said, Yarbo can perhaps offer some goodwill gestures to customers in these situations by offering extended warranties, additional accessories, etc. So far, my dealings with Yarbo have been very positive and they’ve been going the “extra mile” in my case and I’m hopeful that this will continue not only with myself but with all customers.

I personally feel Yarbo support is improving. I think they are adding resources and doing what’s necessary.
That’s all just my gut feel though.

I just got my replacement core today. Switched over all of the antennas and added it to my account. I can connect to it using the app and everything seems ok, but I am getting no GPS signal. Always had a strong signal with the old core. Also it keeps saying it needs a firmware update.
Am I missing a step? Do I need to do some sort of registration with the RTK antenna?
Thanks!

Did your replacement come with a new data center? If so, did you swap it out? Did you complete the “Reinstall Data Center” in the app or follow the install data center process? If not, make sure the you’ve done this step (for either the old or new DC, your choice) and make sure your core is activated in the app (first). Also make sure you have the latest DC firmware update installed. If all of that is still giving you no GPS, then please post a diagnostic screenshot. Include Rover, Status, Data Center, and Halow sections. You can blur the GPS coordinates (GNGGA).

Yes it came with a data center, but I really dont want to change it out with the old one since I installed it very high up and I am not a big fan of heights
Can I use the current data center? Just use the “reinstall data center” option in the app?
Yes the new core has been activated on my app. I can control it and it recognizes that the mower module is attached.
Thanks!

Yes you can use the old one. And yes, just do the reinstall data center in the app. Note that if you have any current maps on the core it will erase them. I’m assuming you don’t so that shouldn’t be an issue.
