2. Turn on Airplane mode…wait until you see airplane
3. Turn off Airplane mode…wait until you see Wi-Fi signal
4. Open Showbox App immediate after you see Wi-Fi signal
Shout-out to Rebel Image who originally found the fix
Still having problems? My showbox app is still working so it’s difficult for me to find a fix that I cannot test out myself. But what I have done is extracted the showbox app that I have on my tablet as an apk file and uploaded it here: http://www.mediafire.com/download/tkbiivs5oh6zxa5/Show_Box_com.tdo.showbox.apk.
I suggest uninstall the file you have on your tablet, clearing data and cache, downloading the other showbox apk file from the Video I provided, then reinstalling. I don’t recommend updating the app because I haven’t update mine and it still works. Good luck.
