I was probably unclear.
My eReader is starting properly with the rev. E image provided by DNSB. But I would like to run with waveform tables and a VCOM value as close to the original as possible.
Unfortunately I don't have an image of my Libra 2, and the original microSD card is completely dead (it was not detected at all on 3 different machines with different OSes).

1) Waveform
I happen to have a screenshot of the firmware information, which includes the waveform identifier (400_B068_HH1D01_ED070KH3U3_VD1400-GOB_TC).
I thought I could use this identifier to find which of the images (obtained from this forum) has the display –and thus the waveform partition– "closest" my Libra 2.
I can guess what some parts of the identifier mean but not others, which makes it difficult to choose.
But maybe it doesn't matter and I should just use the one included in the rev. E image?

2) VCOM
This may be easier: I managed to find the VCOM number of my display. It was not written on the display cable, but encoded in the QR code.
Does anyone know where it's usually stored in the microSD card image?
Or does the vcom.txt trick explained here (for newer Kobos) also works on the Libra 2?
