Hello,
In the past I have successfully installed new maps before but as of today I could no longer update the maps on my device. When running the copy script it goes straight to 100% within a second and claims it's completed the tasks.
I used the exact same drive with the exact same files, only switched out the map files.
Here is an old log of when it completed;
+ mount -o remount,rw /system
+ chmod 777 /system/lib/libigo_jni.so
+ cat /mnt/udisk/updates/libigo_jni.so
+ >/system/lib/libigo_jni.so
+ chmod 644 /system/lib/libigo_jni.so
+ cp -
