Help Needed with Pinout Reverse Engineering For Xiaomi Redmi Note 5 screen

I am trying to get the pinout of a Xiaomi Redmi Note 5 screen. I have been able to identify 14 GND pins, 5 differential pairs, and A K1 and K2 (for the backlight) I also found a pin that will short with GND for a second then flash off then back on, and then another pin that shorts with GND, but will also short with a bunch of the capacitors and resistors on the flex PCB.

If anyone has any ideas or tips on how to figure out what the last 11 pins are, I would greatly apricate it! I have no clue what to do from here.

Here is my current list of all the known pins.

1 GND
2
3 GND
4
5
6
7 GND
8 Saying GND then flashing off then Back to GND over and over and over again.
9 GND
10 GND
11
12
13
14 GND (Shorts with Resistors and capacitors)
15 GND
16 A
17
18 K1
19 K2
20 GND
21 GND
22 Differential Pair
23 Differential Pair
24 GND
25 Differential Pair
26 Differential Pair
27 GND
28 Differential Pair
29 Differential Pair
30 GND
31 Differential Pair
32 Differential Pair
33 GND
34 Differential Pair
35 Differential Pair
36 GND
37
38
39 GND
40
