Can It Be Fix???

Jul 27, 2013 06:56 PM

Hello, my name is Angel from Thailand. I have the Samsung Galaxy S4 GT-I9500 which is not work normally right now. Everytime when I attempt to make a call it will be "Not registered on network"

I've contacted the Samsung service in my area already and the technician there told me that probably when I sent my phone to repair shops few months ago they may have erased the EFS Folder in my phone when they try to fix the EFS issue and repair the IMEI for me.

The Samsung tech.

told me that in that EFS folder has the "CAL" which I learned later that it's the "RF CAL" has been erased that's why I can't make any call... and there's only two way to fix it... first, send the phone back to Korea because only the technicians in main company there can fix this issue... second, change the board which will cost me about 200-250 US.

Dollars since I don't have warranty because I bought this phone from outside country and it's been root already.

So, I would like to ask anyone here if there's a solution to this problem that can save me from paying 200-250 US. Dollars. Honestly it's been very expensive for me...

The phone right now can connect to WiFi and use social app normally... I can make free call from those social apps to my friends if they are online... but I can't contact anyone through normal call...

I've attached the screenshots of my phone also... Hope anyone will have some idea... or if there's really no way to fix it then please, let me know... So, I can move on...
