[X3] Intermittent system reboot when accessing bookmarks via home screen shortcut #892
Description
Device
X3
Affected Version
1.6.1
EPUB Optimization
Yes, using the built-in web transfer EPUB optimizer
Cache State
No / Not Applicable
Describe the Bug
The Xteink X3 device occasionally reboots (crashes) when accessing the bookmarks list via the home screen shortcut on specific books with many bookmarks.
Additional Question / Feature Request: Bookmark Migration
Is there a supported method or recommended workflow to migrate/transfer bookmarks from an Xteink X3 to an X4 Pro?
Since I'd like to change the SD card directory structure, manually copying the database or bookmark files directly doesn't map correctly.
Thank for your work!
Steps to Reproduce
- Open the device and locate one of the affected books (where a high number of bookmarks might be present).
- Try to access the bookmarks using the home screen shortcut.
- Observe the system crash / reboot.
- Workaround: Open the book normally, open the internal menu, and access bookmarks from there (it opens successfully).
Expected Behavior
The bookmarks list should open normally from the home screen shortcut without triggering a system reboot, consistent with the behavior from the in-book menu.
File Provided
I've attached it
