How to wipe the cache partition of a Samsung Tablet? I am trying to wipe the cache partition of a Samsung Tablet GT-P5100 which does not start the Android operating system any more. Only the Samsung logo is displayed before it starts over.

Therefore, I launched the recovery mode and selected the menu entry wipe cache partition as shown on the first photo:



When I press the power button the Erasing ... starts as shown on the second photo:



Right after, the erasing is stopped by an error as shown on the third photo:



Finally, an Error! stops the process as shown on the fourth photo:



Immediately, the device restarts.

What is going wrong?
I have deleted this answer as i am not sure this Texas Instruments (TI) OMAP 4430 SoC is shipped with fastboot mode at all. Ususally Samsung devices have Odin Download mode, please follow this instructions instead
