Is it likely that this (bad battery) is also the cause for the uboot problem (uboot prompt ignoring any input)?
Yesterday I was able to temporarily make it boot normally. But iirc uboot shell was still unusable as described. I then unplugged some wires, because I again wanted to look at the back of the motherbaord. After that, the battery issue reappeared.
What is imx_epdc_fb? Maybe the line
Code:
imx_epdc_fb imx_epdc_fb: unable to set VCOM = 250mV (err = -22)
is caused by not having connected the e-ink display correctly?
In the following image, is it correct that the chip/connector at the top left (J1603) is for the e-ink display, and the one at the top right (REV02 written on it) is for the touch sensor?

In an attempt to remove the battery I used some force, which bend the battery a little. Can such bending cause such battery problems?
I already have checked the connector before, however I don't have a microscope. Sorry if this is a bad question, but what would I look for anyways? Just bend pins and dirt/dust?
