Samsung tab 3 powers on and display shows the word Samsung but doesn“t booth up – left it for more than an hour and all i got is the word Samsung on the screen
Instead, I would try to get into recovery mode (with tablet powered off, press and hold Volume Up, Home, and Power buttons until the Samsung Galaxy Tab 3 logo shows, and then release the Power button until the recovery mode is visible), and start with clearing the cache (volume buttons in recovery mode moves the selection up or down, and the Power button selects the highlighted option). If this does not help, you may have to factory reset your tablet through the recovery mode. If neither of these work, try Hovsep's suggestion.
I forgot to mention that performing a factory reset or Hovsep's suggestion will delete all files on your tablet, so your information and data will be lost.
If Samsung tab 3 will not longer enter Recovery mode then you have to reload the firmware
To perform a firmware update :
- Install Kies
- put your Samsung tab 3 in Download mode: 1)Shutdown Samsung, 2) press and hold the Volume Down and Home and Power buttons simultaneously, and release them all when you see the Samsung splash screen
- connect Samsung Tab 3 to your PC with the USB cable
