I did the same thing, halfbrick my tablet after trying to remove the trojan. Something went wrong. Now i got a firmware (not the original) reintalled but wifi and camera are not working. Cannot retrieve to right firmware. I test 5 differents without success. After donate in your site and read almost all the forum, i found no clue on how to fix it.
thanks for the support.
The Chinese now hide the trojan in the boot img, and I have no modern device to test / develop further on.
For me, it's game over, with no sponsors and just barely enough to pay for the hosting I'm out of the Android game (since 2013, almost 3 years already) I've developed this tool in a attempt to get some extra cash and buy / support new Android devices, but that has failed! The tool works for older devices just fine but now with the new trojan it indeed fails.
I have no idea who else cares about AllWinner and their trojans nowadays.
If you want your donation back that's fine and understandable.
