HI there, I just recently unlocked my Rogers phone and now its online Virgin Mobile. I put in the code and it gave me an error so I looked it up and it had to do with the firmware not accepting the code or something like that. I then decided to use the stock Rogers Firmware, the installation went smoothly then when I actually had it running I couldn't connect to the WiFi (it would say turning on but it wont.), Virgin Mobile network won't show I always have to go to settings and search for it and when I do get on the network and put my phone on lock I would get no service until I search for the network again. Also, when ever I make phone calls the screen turns black and nothing happens. My home phone would ring but nothing from my cell. So I decided to install Google Play Rom and it's the same thing.
Can someone please help!

Hi all,
I've had my phone locked on Tele2 (CRO) network which I needed to unlock to be able to use T-mobile SIM. I've used Odin 3.04 and followed the instructions to update modem to I9505XXUFNB9. I've managed to unlock the network this way and use my new SIM but the connection (both phone and mobile data) kept switching on and off constantly.
After that I've tried another firmware, namely I9505XXUFNDG for T-mobile but the problem now is that mobile is almost always off with no possiblity to connect and WiFi is blocked completely (security notification "Your device's security has blocked an action").
Basebands registered properly after every flash.
Phone is not rooted and me not being a power user would just love it to work as it was intended to
Followed the guide, all firmwares downloaded from here
Appreciate any help.
Might be onto something. After reading through this post seems I need to apply WiFi fix but I cannot tell which one to use for my phone (I9505XXUFNDG) as it's not posted. Kernel version 3.4.0-481100.
I've tried I9505_WiFi_FIX_MDM.tar and I9505_WiFi_FIX_MDF.tar but they just messed up the phone completely.
Thx a lot.

Hi ,
you should flash the fix for the modem you have installed , try following:
Flash another modem from the list there
Now flash the modem wifi fix for that modem
If still in trouble re flash stock and start all over again.....

Thx, did just that and now it works properly.
Much obliged.
a problem started to show recently; when i select LTE/WCDMA/GSM for auto connect network mode when the mode switches due to signal availability it doesn't get reconnected. i.e. while under LTE it works fine but if i move and get out of reach it should automatically switch to slower network which it doesn't. this works fine if i select WCDMA/GSM then the switches are fine but LTE is not available under this.
one more thing i noticed since i'+ve flashed the phone is that the upper part of the phone gets very very hot (a lot more than before). since the flash i've also had to replace a microSD card which died within weeks (not necessarily connected but worth noting).
any suggestions welcome.

This phone used to be on the Bluegrass Cellular network, I have contacted them and AT&T with no help. I have rooted the phone using Towel Root and used Advanced Signal Status to change my radio to LTE/GSM auto, and can also now change the radio options within the phone. When I select to register on the AT&T network, it sits for about 3 minutes, and says "Unable to register" the IMEI is clean, I'm assuming I need a custom firmware or something. At this point, I am willing to pay someone to help me fix this, it has caused me so much trouble. Thanks!
Someone had suggested I use This ROM.
Problem is, I need custom recovery, and I can't find one for jfltelra.
TWRP shows all the jflte's but mine (jfltelra)

Use twrp for jflteusc works great.
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: . And when I tried to call a sim card in my I9500, I hear ringing tone during call attempt but there is nothing on SGS4.
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.
I recently purchashed a A5 (SM-500H) from a carrier (Claro) in my country and it came with stock 4.4.4. I decided to flash an official Samsung 5.0.2 update from Saudi Arabia, everything was working fine (I could make/receive calls, use wifi, etc) but then I tried to use mobile data and it shows the "H" and arrows you get when you're connected to mobile data but when I try to use internet it doesn't load anything.
I already tried to change the APN settings, but it still doesn't work. I tried almost every solution to similar problems but they didn't work neither.
My IMEI is still there if that matters.
What should I do? Should I just flash the 4.4.4. rom again?
Thank you so much!
Reset the phone 2 time it will be ok??
