PERFECT ! The 2nd time it arrives, the first one I opened the box with a few damages, shorted the cell and it worked. This time I drilled with a column drill (not to drill all the display !) at 5mm of diameter. I respected the location of @MrKlaad ("It is ~15mm from long left side and ~35mm from top short side "), took care of the side right or left and it fits perfectly (see on the image if I can publish it where it falls). I will put a bit of silicon on the hole and the next time it will arrive my session will not fall down : I retire the silicon, use a BTR key I have on the bike with several tools to short the battery, put the silicon on the hole again and do my session. THANK YOU for the video !
Thanks for the video Rik, Look, I dind't undestand the part of the white and green cables, waht did you said they are for ? The brown and orage I could understand, but not the other two. Thank you in advance.
Thank you, quick shortening +-from the small baterry recovered my 850c. I have drilled just a small hole on the back of display, so we don't have to unglue the frame and the screen from the front.
You unclip first some sort of small bezel. Then try to separate the clear screen without breaking it using a fine blade and some heat and after that remove a few small screws to get the board out. I just found another video with a solution if you want to do drill a hole, so without opening the display... ruclips.net/video/t2jUsGz6d_o/видео.htmlsi=QP_joV8Z4retvsIr
Thanks this totally works don’t no if shorting them lasts long yet but a quick hole on the back to short the cell for a few seconds certainly got my bike going again.
A short touch should be enough. When the e-bike is on that small battery will get charged but it takes a very long time charging to 3 volts. If i remember well i calculated it at around 70 hours reading the specs. So best to ride the e-bike regularly :)
My 860c display boots up, but then horizontal lines shows up, and graphics start to freeze, motor and throttle works. Malfunction keeps happening. So it looks like the display is not dead. Should I replace the battery? Will that be the case with a small shortenong + wit -
This fixed my 750C display. Dragged my multi meter lead over the battery connections a few times quickly and its working perfectly now. Thank you!!

Worked for me! This is why I love RUclips.
Thank you Sir!

These are the communication wires, RX and TX.
Fixed it. Thank you so much for posting this video.
How do you short the battery would been nice to see that
Thank you for your time. I bought one but it has a four-digit lock. Is there a way like factory reset or something similar?
Try 1919
Did you ever get your display unlocked I am having same issue
Hi Rik, thanks for the tips.
My glass is broken, display is fine. Were did you got a new glass?
Do you have a link to share?
Nope sorry, no spare glasses exist as far as i know.
Thank you, quick shortening +-from the small baterry recovered my 850c. I have drilled just a small hole on the back of display, so we don't have to unglue the frame and the screen from the front.
Can you explain where exactly did you drill the hole?
Thanks!
I think mine will be getting a hole also
It is ~15mm from long left side and ~35mm from top short side

That sounds more like a bad solder joint or bad display contacts.
I have the same issue with 850C. Probably opening the case went wrong. Well it didn't work in the first place.
