Thank you everyone for your replies, I really appreciate them!

I have actually opened my device to see if I can save it. I’ve contacted Pocketbook customer support as well (well, Vivlio in my case) but didn’t get any reply from them yet.

So I have decided to disassemble the device.
It’s not a Kindle, so it’s not glued together, and the waterproofing is supposed to be achieved by the special coating on the PCB - same as Kobo Libra 2.
There were a few drops of water inside, which should have been fine. I believe that the difference between running water vs water pressure shouldn’t have mattered in this case as the result would have been the same, given that the case is not watertight.

The connectors on the PCB were covered by some sticky substance (silicone?) and by some yellow sticky tape above it.

However, the tape above one of the connectors (I believe that it’s the display connector) was not fully attached to the sticky stuff below it, and there were a few drops of water underneath this tape.
I have disconnected the battery and left the device to dry overnight.

I have tried to turn it on in the afternoon and it did, but only the top half of the screen appears to be working. I can use the navigation buttons and even the touch layer still works.

I’m wondering if the water droplets got to the display connector (that was not watertight due to the poor assembly) and damaged half of the pins. Does this conclusion make sense?
