Hi XDA . I think i have a serious problem. On my phone J5(2016) SM-J510FN i had android 6.0.1 and root. I recently saw that my phone got an update for Nougat. I downloaded the firmware from Sammobile but couldn't flash because i was in TWRP recovery so i installed FlashFire and flashed from there . It did what it is supposed to do but when it restarted it still had SuperSu installed and i hard reseted it and now i cant turn the wifi on and i cant connect with a computer in any way . I tried different ports , different cables and PC-s but it doesnt show up at all or only once it shows as an Unknown Device and says lastest drivers are Installed. I now have stock recovery but when i select Apply Update from SD Card or Apply Update from ADB it shows that Apply from external storage is Disabled and shows "E: unable to locate /dev/block/bootdevice/by-name/misc " . Please help me if you can .
