Hello, thank you. You are right. Unfortunatelly, it is very problematic to make some changes as it is squash fs, little indian as far as I know. I have read only problem with my card, I wanted to try https://luator.de/linux/2019/11/23/p...ce-memory.html solution, but I have not found how to do it, it looks to complicated for me, because it is not possiblke to address all folder as shown and also SD_prepare.zip prepare two files, but they are zero size, empty...

If someone would have any help or recommendation I would be happy. I know that PocketBook 840 is old type, but it is only 8" I can find. There are only 10" or 6-7" on the market, and it is too big or too small, I really like 840 InkPad 8".... Thank you very much.
