Xiaomi mi 9T missing resistor

[badcap111]

Hi, while trying to replace a broken screen connector on the motherboard, I knocked off a resistor next to the connector, and the resistor vanished. I have tried to find out the value of the resistor by looking at the schematics, but I cannot find the value. The ID of the resistor, or what you should call it, is R6400.

I don't know if the resistor is necessary for the phone to function, and the connector is still not soldered on to motherboard. I have contacted Xiaomi and asked them if they know the value, but they want a proof of purchase, which I don't have.

Is there anyone here, who has experience of Xiaomi and knows the ohms of the resistor - ID R6400? I have searched the Internet but I cannot find any answer. The schematics are not helpful.

Post pictures if you can, and share the schematic by posting it in the schematic requests sub forum https://www.badcaps.net/forum/forumdisplay.php?f=41

Now I have a photo of the area:

The missing resistor is to left av the text 3501F... The connectors ID is J6401 and the resistor is R6400.

R6400 characteristics : 0R; 5%; 0402

Wow, thank you. I think understand a little better now. I thought that '0R' was a word type, a conjuction and read it as OR,not 0R. So I guess that R6400 is a zero ohms resistor? Is such a resistor essential for the functionality of a phone?

Yes,it must have continuity,just put some 0ohm with same size on board
