Hi all.
I had s4 active which was locked to AT&T and went for unlocking. He downgraded it to 4.3 and unlocked but that dint work instead showed samsung custom with key padlock.
When i keep a sim and call a number, it hangs up and screen flashes. after repeated attempts, went to boot recovery and did factory reset. Now phone has been struck on boot and it just stops after samsung with blank screen.
Please suggest me anything for it. What could have happened? How to reset the phone back to 44 or atleast 4.3?
Will it get locked if i update it to 4.4 again?
Thanks in advance.
