Hello everyone, i rooted my phone and flashed a custom rom to my S4 and i could even restore it to stock once but when i rooted it again and flash another custom rom i can't get back to stock!
odin keeps failing whatever i do it says "Can't open the serial(COM) port." for 4.4.2 stock
and "Complete(Write) Operation Failed" for 4.3 stock rom and i just cant do anything with it, i tried uninstalling the phone drivers and installing them again what should i do ?
