Just received my crankset/power meter set. During registration I was notified of the software update and started the process. While updating my phone went to sleep. I woke it back up and had to “manually” finish the update.  But after the update-I wasn’t able to connect to the unit with my phone. Doing the magnet reset fixed it all.

For anyone who needs to know how to do a magnet reset — pop the charger on the unit and plug it back in. While plugged in, bring a magnet and hold it just above the charging light (with the Magene logo reading normally) till the light blinks a couple times. That should take care of it.

Not for USA shipping

I put expensive batteries in mine and i very rarely charge it, the battery lasts for a very long time. The charging port is a major flaw though, and a source of stress. I have an ERX derailleur because my ER9 died, and after not that many miles on it, the charging port is already causing problems. For the cable to charge, you can't just clean the port and connect. Sometimes it works, sometimes it doesn't, it's shit. 100% a design flaw, which they addressed in the newer versions with usb charging. I do have back up option, as a geek: i have a lithium charger (opus something), so worst case, and it's happened several times already, i remove the batteries from the seat post and charge them on the opus. it's a faff, but they hold their charge a very long time, so it's not the end of the world. It does suck though.
If anyone figured out the magical sequence to get it to charge properly, please do say.
