Secondly : I usually update my Galaxy S 4 using Odin without problems but when i tried to update my Galaxy Tab 3 8.0, PC recognize the device when it's turned on and recovery mode, but do not recognize it when i enter Download mode. What to do ?

Tried : Using the original USB, Changing the USB, USING S 4 USB (which is working with s 4 in download mode) , RE-installing Samsung drivers and finally changing Odin's version

Result : Problems not solved
