With a Chinese IBex (genuine) Superpad 2/Flytouch 3 I had to try three different versions of firmware before I could get it to work as intended. On one OEM version it would just 'Force Close' when trying to export the database. Using the 'Tim6a' firmware it would work normally but installed the 'memento' folder internally and not on the SD card. It works normally using the 'Tim5a' firmware.
