Hi xda team,

Sorry for my bad english. I have a serious problem on my SGS4 I9500 and I checked on this forum and web searching for solution but nothing :crying: .

I bought a SGS4 (I9500) 2 week ago. The phone was working without problem on KitKat 4.4.2 (sorry but I don't remember which version of KikKat) until i decide to change rom and to update to lollipop 5.0.1 (I9500XXUHOA7). After flashing my rom I can't make calls/sms and can't access to internet through 3G because my phone doesn't recognize my sim card. There is a message saying "Not registered on network" and IMEI was generic (starting by OOXXXX...).

So I checked on XDA and internet to find out the way to resolve this issue and I tried many things:

• Change modem : I tried to change my modem to MODEM_XXUGNL1. IMEI back to normal (starting by 35xxxxxx...) but I still can't make calls/sms and connect 3G


• Downgrade FW : I downgrade FW to KitKat I9500XXUFNB3 but IMEI was null/null. I change modem with Modem GNJ6 (Modem.bin). IMEI back to normal but I still can't make calls/sms and connect 3G because when I tried to call/sms I receive the same notification saying that "Not registered on network"


• Register network manually : I tried to register network manually. My I9500 tell me that sim card is registered but when I try to call I see "Not registered on network"


• Wipe data/cache : I wiped data/cache using Samsung recovery and philz_touch_6.12.8-i9500 but nothing :crying:

Note that my sim card is working fine on other smartphone and other sim cards not working on mine. Always the same message "Not registered on network" :crying:

I'm disapointed and don't know What I have to do to repair this issue. I know that you are wonderful :good: and I hope that you will help me to find a solution for my S4.
