I've rooted my Samsung SM-G530BT running Odin3 v3.09. Everything went fine, I've checked and it was rooted as expected. But then I reboot my phone and know it loads the phone model logo but then it shows only a black screen. I've tried all methods to enter Recovery mode and nothing works. What do I have to do in order to restore my device? Is there any software that I can use in my PC to recover? Or even restore the intial settings? Thanks everyone
You can recover your device by flashing stock firmware.
First download stock firmware for your device from sammobile.com(or any other site) and then flash it using Odin the same way you flashed TWRP or whatever to obtain root.
