Root my android tablet I have a 3Q lc1016c tablet, and i would like to root it, i have been trying to install the su through the update.zip but the installation aborted. There is an official release to update the ROM (update.zip) and it worked fine, i tried to take that zip and added the su but when i zipped then signed it and try to install it, i got the same Error, so i do not know if there is some special keys to sign with or. I want to understand why the official one is working and when i zip and sign the same folder it doesn't work.
It sounds like you're not using the correct update.zip file for your model; if the software/hardware architecture is not a match, installation will fail.
