Whilst doing some work on my new bike build, I unplugged the front derailleur of my L-TWOO eRX groupset. Upon plugging it back in, it had completely died...

The L-TWOO eRX is the first electronic groupset to come from a Chinese company, and due to the relatively low cost of the groupset, was set to rival the big entrenched brands like Shimano with their Di2, and SRAM with eTap... but maybe not.

The whole groupset was working totally fine before unplugging it, and I'd actually ridden 55 miles on it the day before, with absolutely no problems.

I have tried everything I can think of to bring it back to life, but after trying for a number of hours, it's still dead. As I demonstrated, it does move slightly when being plugged in, but that is it, nothing else happens.

Massive thankyou to Joe from @ChinaCycling for trying to give me a hand. He faced a similar issue, but using a trick where you re-calibrate the front derailleur in the app, his came back to life. No such luck with my setup...

VERY frustrating, but not much I can do. If I get it working, i'll post an update!
