GDEY0213B74 2.13" not updating, using seeed driver.

[Tsquash]

Hardware:
Seeed XIAO C3 MCU
Seeed Driver Board (More info here.)
2.13" Display (GDEY0213B74 122x250, SSD1680, FPC-A002 20.04.08)

Problem:
The first time I ran the GxEPD2 helloWorld example on this hardware, the display started a full refresh, but stopped while it was mostly black but with a little grey. No matter what code I run now, and if I run the same code again, nothing happens. It has been stuck on this same screen since that first run. I am not getting any busy errors, and the serial output looks normal from what I can tell. All libraries and dependencies are up to date. I have posted the code and output below.

I am honestly lost as to what the problem could be, and I am coming here as a last hope. Someone on the arduino forum suggested using a 2ohm resistor for RESE since this is an SSD driver, but even after changing the 0.47 to 2, I am getting the same output. Any help would be greatly appreciated.

If it is any help, I have tried this same setup with a 7.5" GDEY075T7 (with the 0.47ohm RESE however), and I am getting similarly weird results. It updated once or twice when first using the display (not properly), now nothing is changing and some residual ink is left over. With this display particularly too, it gives a BUSY timeout warning for every command. Hope this can narrow the problem down.

Make sure your connection to the panel is ok.

The connection board has no RESE switch, and there is no schematics.
E-paper panels with SSD controllers should be used with a RESE value of 2 or 3 Ohms, UltraChip controllers should be used with 0.47 Ohms.

From the symptoms you mention it looks as the connection between the driver board and the panel is not stable.
A look at the picture seems to confirm this.
Did you loosen the mounted connector by lifting up the black lever, then inserting the flexible connector well aligned, then pushing down the lever to fix the connection?

How could you change the RESE resistor? Did you find the schematics?

[Tsquash]

The panel is connected to the driver board securely by using the black lever, and it is aligned with the FPC connector pins. What about the picture looks to be connected unstable?

I do not have schematics, but there was a 0.47 ohm resistor near pin 3 of the connector which I desoldered and soldered in a 2 ohm.

Solved: The MOSFET near RESE on this seeed board must have been burned out. Desoldered it and soldered on this part, and it started working immediately after. Thanks for offering help!
