@autoprime ?

Canadian ROM only shows 4G signal icon (with LTE speeds) - why ?

Hi all,
I recently bought a Galaxy S4 337M that was rooted and loaded with a custom ROM. I decided to go back to stock so went to sammobile.net and got the latest rogers firmware for my galaxy S4 (which they said was 4.3).
I loaded with ODIN, all went well, rebooted stock, but the max signal icon I can get now is 4G (even though I used speedtest and am getting close to LTE download speeds I think). Any idea why my LTE is gone ? Did I download the wrong ROM ?
I also noticed that none of the APN settings were there and no rogers apps were installed either. Makes me wonder if it was indeed a stock rogers rom after all.
Another strange thing is that it shows me a bell canada navigator update is available in the google play store, yet its not even on my phone. Regardless, even if its a Bell ROM by some chance, Bell Canada has LTE as well, so I am confused.
Btw I used the standard ltemobile APN settings that I always use on all my phones to get LTE (that always work)....
Any help or suggestions would be really appreciated, thanks so much !!!
My iPhone shows LTE using the same SIM...
PS. If I do need to get an original Rogers ROM, is sammmobile not the best place lol ? Any other places to go??

I believe that all I337M uses that same firmware but you need a CSC changer to make it change to your carrier as they don't release the specific ones with the carrier apps.
Search "Samsung CSC" in the play store and you should get one.

Thanks for the reply.
Seems I need root - which I deleted when doing a factory restore.
The strange thing is that it was supposed to be a rogers based firmware that I downloaded and flashed.
Maybe something went wrong in the flash.
Will try again.
And check out the CSC

i have a bell i337m and i have the same issue when flashing from a "custom rom to stock" and i have to flash the firmware using odin a second time and than i get my LTE icon enstead of the 4G icon, sounds weird and i can't explain why it takes 2 flashes to get it to show up proper, but it does.
i also have the problem with missing phone vendor apps, the second flash also makes these show up too.
also another thing i noted about my phone is if i don't root and install recovery to wipe, odin will dirty flash my roms, even though odin is supposed to wipe it isn't.
i've tested this to no ends, the results are 100% the same everytime.

After flashing the stock Rom, go back into stock recovery and wipe data and cache, then reboot that should fix it. To fix your csc issue there is a way to do it by dialling a number on your dialpad which includes your imei number then you choose a specific code. Search for it, google

Thanks so much for the replies and help.
I wiped the rom just for fun and rebooted and noticed that its actuality a BELL ROM (all stock BELL apps etc), but when I entered my rogers APN settings it still only showed H+, maybe due to network differences. It's frustrating because I specifically selected a Rogers S4 ROM from Sammobile.net. Any idea where I can get a stock rogers ROM for s4? Also do you think this may have affected my 4G/LTE issue ??
Either way, I will definitely flash the correct ROM twice, and then go back into stock recovery to to wipe data and cache.
Thanks again for all your help

follow this guide, http://www.droidviews.com/how-to-change-csc-in-samsung-galaxy-phones/ real easy, itll put you back to a rogers rom, all the firmwares on sammobile are BELL ROMS. you have to change the CSC yourself.

THAT WORKED
Thanks so much !!!

Galaxy S4 Gt-i9500 network problem

Hi All
i have GT-i9500 international . IMEI were changed to work on Turkish mobile networks.
it was working but after upgrading to 4.4.2 Network register but always : Emergency calls only.
i can call 112 normally .
when i go to mobile networks and search: i find my network : Turkcell. and when i choose it " Registered on network.
but : emergency calls only.
in service mode : IMEI CERTI:Fail
i downgraded to 4.2.2 but the same problem.
when i dial : *#0011# : UMTS: Home(CS+PS)
when i chose back from menu nothing happen.
i tryed all solutions in XDA and Others , tryed all modems. the same problem
i am using the firmware: I9500XXUBMH1_I9500OJVBMH2_I9500XXUBMG9_HOME.tar.md5
i cant install any other rom with Odin. just this.
service mode just stick on first page.
any idea to help please?

none
i cant help ,wait for ohther peolpe

* restore your efs backup
* It's very weird that you can not install other firmware. Remember that you can not do MG9 downgrade modem. Try install Kitkat with pitfile.

I used to root my Samsung S3 phone with different types of custom roms but most of them drained out my S3 bsttery fast. Due to this experience, I'm scared to root my Samsung S4 which is still in it's original rom and already updated to 4.4.2. When I looked at your screen shots, I kept wondering why your android OS was so high. I was thinking perhaps it was due to your phone being rooted? Is it because most custom roms drain battery faster than original roms? My S4's battery lasts much longer than my S3. I can put aside my phone with the wifi on and battery at 100% when I sleep. When I wake up, the battery is around 98%.

i have same problem anyone can help me plz
thanks in advance

any idea please

Hi mate,
The problem in the case above is that the phone lost its IMEI , if your case is the same and you do not have a efs backup , you will have to go to a service shop to have it fix , they need a tool like z3x or similar to fix it
http://forum.xda-developers.com/galaxy-s4/help/registered-network-t2810940/page3

thank u,
my IMEI is fine its repaired IMEI "cause here in turkey somehow we have to do that" but as written above i get no network after return it to 4.2.2
any idea?
thanks in advance

Help with my samsung s4 i9505 lte

Hi ,
I updated my phone to the leaked ROM of lollilop 5.0.1 , well this is not a problem the thing is that after flashing it many times with stock and costum roms I corrupted the EFS folder and didn't have a backup of it.
The IMEI is good and everything else , but since I have a major problem is that the phone doesn't get the 3G it is stock on the EDGE network only , now I guess the problem is from the nv_data.bin which after rooting the phone I didn't see it inside the folder , I would like to know if this file is related the 3G and network frequencies and how to write the frequencies and fix this major problem.
Thanks in advance for your help.

ANY HELP???????

The problem is the APN and you can not modify it. Contact your carrier and see if they can assist.

ehrn i purchased the phone it was perfect. connecting internet was showing 4g.. but when i installed this original Verizon rom it became difficult.. now i am unable to root and install custom recovery... please guide me to root and install custom recovery TWRP and i want to install custim rom.. please help

@dipankar.c2bs
You might look into getting your CSC "sales_code" changed. I'm not sure if that is entirely the problem, but it is likely related. Even the USA Verizon ROMs come preloaded with databases that are used to provide custom parameters for a variety of carriers and locations world-wide. (See the file /system/csc/imsprofile.xml for example) I suspect the way this information is actually used is through the "sales_code" CSC value, but I'm not 100% sure of that.
I'm guessing you want "INS" or "INU" instead of VZW
What you currently have:
Code:
getprop | grep -i csc
If your handset is supported by Airtel, one of their technicians will probably know how to do the CSC change, possibly without even rooting the phone.
If it not supported, they probably will be under orders of their employer not to help you at all. But, is is easier for them to give you advice face-to-face, rather than over the telephone (subject to monitoring), if that is possible.
A question to ask - a form of social engineering - is this: "do you know of someone in the area that can help me for a small fee?"
[EDIT]
There is one other possibility for a non-rooted phone. I really don't know if this would work (I am speculating here), but the basic idea is to apply a CSC for a closely related device Model (a SM-N90???? Qualcomm model, hopefully for CDMA/LTE) that is for your country and carrier on top of your existing ROM using Odin. Get the CSC file from Sammobile, and:
- wipe the entire phone using the stock recovery. (You can remove the external SD card first if you like)
- boot the phone, shut down, boot into stock recovery.
- wipe the entire phone again in the stock recovery
- boot into Odin and flash the CSC in the CSC slot.
- boot the phone; do a minimal configuration and see if you have the service you want.
Note that @donc113 s advice given above is the right place to start: ask your service (Airtel) to help you before you try anything yourself.
good luck.

when i purchase it was good... there was 4g indicator also.. no verizon boot screen.. but now it dont works..

One of your friends who installed the stock ROM apparently didn't understand the consequences of what he did. Stock ROMs set the APN for Verizon. Did this friend happen to make a backup before he did the ROM switch?
