Thank you for the quick and clear response, Marek.
I agree, using the dd command to overwrite the root filesystem sounds extremely risky, and it's not something I'm comfortable attempting. It's a shame that a direct downgrade seems to be off the table now.
The main reason I wanted to downgrade was to fix several UI issues that were introduced with the recent update. Since downgrading isn't a viable option, perhaps I could get some help addressing these specific problems instead?
The two main issues are:
1.
Inconsistent font in the page number display: In the bottom-left corner, the fonts for the numbers and the Chinese characters are not unified (e.g., in "第 1 页"). This seems to be a problem specific to the Simplified Chinese language setting.
2.
A change in the highlight style: Previously, highlights on separate lines had a small vertical gap between them. Now, a highlight that spans multiple lines is rendered as a single, solid block, which I find less visually appealing.
My question is: Does anyone know where these UI styles might be defined in the Kindle's filesystem? Are they controlled by CSS files, configuration files, or something else that could potentially be modified?
What's particularly interesting is that some of these changes, especially the highlight style, did not appear immediately after the firmware update. The change happened after my device was connected to the internet for a while. I have also seen many similar reports on Chinese social media, which makes me suspect this could be a setting pushed by Amazon's servers after the initial update.
Any insight into these specific UI elements would be greatly appreciated. Thanks again for your help!
