I have a Samsung Galaxy Tab 4 T235Y LTE 7.0". I have ported and flashed rom and it went wrong. Then I flashed stock rom. Now it's not detecting usb on pc (not showing usb options in tablet like mtp/ptp selection) and only charging device. Also when I turned off the device and put into charge offline charging animation isn't showing. Twrp recovery usb also not working. Usb works only when in odin download mode. Please help me to fix this !!
