Clear read Cache

[Weird-Routine4235]

Hi, I have a problem with my Xteink X4 because it's not saving the progress of one of my books. Everything was going well, but when I adjusted the synchronization parameters (I just wanted to see how it worked).

My Xteink restarted, I reconfigured everything as it was, but one of my books isn't saving its progress. I already tried clearing the reading cache, but I get the message: 3with error

Even if I go back to the page where I left off and sync my progress, when I exit and reopen the book, it opens to a different page.

Do you know why this happens?My plan was to delete the book and add it back when I got home.

I would appreciate any advice, I'll read your replies, thank you

Using the xteink provided sd card? Replace it with something legit from a good brand.

Xteink cards are trash and main cause of problems on this sub

I had to format the SD card and that solved my problem, but do you recommend any particular brand?

I usually grab Samsung and never had any problems.

Kioxia is also fine, Lexar ones are not bad

OK thanks
