Hi Renate,
Continuing from PM, I tried to pull /system/lib64/libota_jni.so but apparently my device don't have them.

adb: error: failed to stat remote object '/system/lib64/libota_jni.so': No such file or directory

If you meant to pull decryption keys, I can pull them from /system/priv-app/OnyxOtaService/OnyxOtaService.apk, jadxed to find res/values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="action_settings">Settings</string>
    <string name="app_name">OTA service</string>
    <string name="battery_level_not_safe">Low battery! Please ensure a minimum of 30% of the battery for the update！</string>
    <string name="can_not_find_update_package">No update package detected!</string>
    <string name="cancel">Cancel</string>
    <string name="disk_io_error">Error in copying update package!</string>
    <string name="disk_space_not_enough">The remaining storage is less than 2GB. Please free some space and try to check for update again.</string>
    <string name="find_update_package_from_local">An update package detected from the local storage. Copying package...</string>
    <string name="hello_world">Hello world!</string>
    <string name="is_upgrad">Do you want to update your BOOX?</string>

    <string name="model_does_not_math">The update package is not for this model. Please download the right update package！</string>
    <string name="ok">OK</string>

    <string name="upgrade_package_is_incomplete">The update package is damaged. Please download it again！</string>
    <string name="waiting">Updating! Do not power off or turn to sleep mode! The whole update will take a few minutes.</string>
</resources>

Running these strings through BooxKeyConvert.py:

D:\Android Tools\decryptBooxUpdateUpx-master> python .\BooxKeyConvert.py EPSLite2C09 JdGNuTFbE2XCV8qiouuFdHwvhcHCdHVVfFh0ODrZDMRs LaSNxzdeYWHYWK/hk8QLz4LkMKxkX+uq1acwVJ1qMXSb

Oh I should attach OnyxOtaService.apk as well...
