THAT SECURE CHECK FAIL ERROR SHOULD NOT COME WHEN BOOTLOADER OR DOWNLOAD MODE HAS BEEN UNLOCKED AND THEN SOME .IMG OR .TAR IS FLASHED In the LATEST UPDATE with BINARY VERSION S4 or U4,I am unable to flash custom recovery,even when I have TURNED ON OE...

Samsung's every update on the SM-T290 is slowing down the 2 GB  RAM tablet instead of speeding it up. Can't use the tablet speedily even for studying. Sick of Samsung's worsening software quality ( but hardware quality is excellent).

Pls try to spread this message to developers.
