I Still have had no response from China with regard to "Re-Registration" after Flytouch 2 (SuperPad) deb firmware updates. I get no response to email. I am not a Linux guy, but I have been poking around the Android system for some clues as to where the registration information might reside. If someone knowledgable would take a look in "system/lib/libeee168_jni.so" with the text viewer; you might find a specific reference to tablet registration. A tweak to get the original registration code to be accepted would be great, for all of us.
