I have followed the post of how to unlock bootloader on every G7 devices ( I currently using G710N version ) , I somehow almost success , but now I'm stuck in fastboot mode , no way out , the phone doesn't allow me to boot , and when I connect it to PC and write those ADB codes , it keeps saying " Waiting for devices ... " , or says nothing and starts a new code line , now I just wanna go back to the stock , but if some kind people help me out , maybe I can continue to finish the flash rom process . Guys please , I'm really panicking right now
