i tried this:

If you are stock, I would try flashing the latest (.27) firmware for your version (SKU). Download from the Asus support site, unzip it ONCE (it will still be a zip) and put that on a microSD formatted for FAT32. Then hold VOL DOWN and POWER until you see the small white text. Release both buttons and hit VOL UP to enter RCK (recovery) to trigger the flash of the stock firmware.
and there is android logo with red triangle and with this!
what can i do? the tablet is on stock please please help me
