This method is maybe known for some of you , i test it for some models (like E250 ,J600,J700 ..) and i think , it can work for all other models ..It's easy ,no risk at all , no cable , no drivers , but need to be handled well Today i test it on J700 , as we know ,many of us have a bad result after using box to unlock that fone ,, (bad Imei ,bad BT adress … ) but with this method ,, EVERYTHING is FiNe 1- Power on fone ,, type : *#7465625# you will identify wich code is active , wich is inactive 2- Remove battery ,, Put your sim card , not all of it ,, just to prepare it to be full inserted , put your battery back and power on fone ,, you must see " insert sim" not "invalid sim.." 3- type : *2767*3855# your fone should restart after 1 min ,, now ,, and before it restart , push your sim card ,,without removing battery 4- your fone should work and accept the sim card….
I didn't find the right solution from the Internet.
