Bro....,
As a junior mrmber you wanna learn more things... Z3X like a beauty girl. Its amazing....it has attractive features... but sometime very hard to understand. It works with us the time that it wants... Its not a new thing in this field. Mobile companies make a big mistake when manufacturing phones. So we can never find bug less tools. But with good understand we can make money with that tools. Z3X samsung best tool. It has some bugs. But its the best tool for Samsung

I9300 IMEI repair i am still not tested. But with my experience in Jelly bean coming some errors.. Sometime may be rooting error... You can try downgrade root and repair using Z3X..

you must flash phone. After flashin your imei will be 0049.. Enable usb debugging and connect phone. install drivers. And press repair. when phone rebooted connect uart cable. It is ok.

I have your same problem, I can not connect with UART cable, how do you repair it ?, what's the modem IC ?

[Ransiri]

As i think modem ic is baseband processor. XG626 IC no. I dont know how to rehot it. Normally comes with covered glue
