I don't understand what is exactly happened to my Galaxy S4. I can upgrade to official Lollipop but I can't use any newest modem on it. It's only work if I restore my kitkat modem and EFS folder (fortunately I always do backup it with Philz).
Cause :
Someday I've found my S4 won't charging and it become so hot. Going to Samsung service center and they said I have to replace the mainboard, it's price about $150. I won't pay that much for 3 years old handphone. So I decide to try it on local repair shop. They said the power IC is damaged and they charge $30 for repair. Now my phone is working normally. My phone coming back to me in Kitkat firmware and I have no problem with that. So then I upgrade it to Lollipop with Odin then I realize it's not working with lollipop modem. I try almost every region modem and nothing work. I can use some custom lollipop ROM like ATOM, Omega and the other which is not flashing modem on it. But it's not work with Ale95 or Firstflight. I will got Imei Null with the stock lollipop modem, and if I restore my KK modem it would said IMEI Certi: FAIL on *#0011# service mode.
note : before I bring the phone to repair shop, I has no problem with KK or LL custom rom and using XXUHOD4 modem. I can install everything.
Question :
1. What is happening? is my device got region locked?
2. Is CSC, bootloader, modem and efs are related?
3. Any ways to fix it so I can use Lollipop modem again on my device?
