Hello, I picked up a sanei n90/ampei a90 a couple months back; all was well until I installed a firmware update a few weeks ago. Now it doesn't boot past the 'My smart my life' thing with the obnoxious flashing android head. It just hangs at that bootscreen. When i try to upgrade, I get the broken android logo and recovery mode. I've downloaded a more recent firmware (i've tried both the a90 and n90 varieties), but it's just a few image files and a chinese pdf. Livesuit calls them all 'invalid'. I've managed to get the thing into recovery mode, and i put the most recent firmware onto a microTF in hopes of 'apply[ing the] update from external storage', but that option just shows me an empty folder. I've tried the factory reset and everything, but i can't get this tablet to fully boot, update, or do anything useful whatsoever. And i've tried damn near everything. Help, anyone?
