ZT-UPDATE Folder contents: clear_data_part
The contents of your zt-update folder is a complete mess. The ZT_Bx.* files are for the original 10" ZT-180, not your v2. Also the *.img files are for really old ROMs for the original 10" ZT-180 tablet also to be burned via burntool over usb, again, not for your v2 tablet.....
You have to figure out which v2 board is in your tablet, a G0 (blue in color and has 512MB RAM), G1 (green in color and has 256MB RAM), or G2 (green in color and has 512MB RAM), then we can help you figure out which files should be in your zt-update folder (if you are looking to update your tablet).....
