Help, cell signal acting weird after ROM

Hi, I just put in Darky's rom onto my Bell Samsung galaxy but my cell signal seems to be weaker and sometimes just loses signals. This hasnt happened before and I'm wondering what the problem is. The bars would go up to 3 then 2 then nothing and then back up to 3. Thank You.
Edit: It appears im on GPRS network and I believe I was on GSM network before so does that make a difference? I'm on Rogers network btw.
I also have speedmod k12h on it as well.
It seems im on the GSM 1900 and I guess I lost GSM 850? Anyone wanna help me?
Dont have data plan as well

Darky's rom
You have changed the firmware including the modem .
I would ask Darky for solution its his rom .

Help!! No GSM Signal only works on 3g signal

I am unable to connect to GSM only network ... My N4 while roaming out of city limits doesnot catch GSM signal .. it only works with 3g signal .. I noticed this issue just a week back and it has kept me worried .. Can someone point me to a proper direction with regards to this issue.. I flashed the latest available radio JDQ39E but still no luck.. there is no GSM signal.. My nexus 4 has the latest 4.2.2 rom in it.:crying:

Where are you at? Which network? There are areas (rare but there are) where t-mobile is wcdma (3g) only.

[Q] Odd LTE Signal Swap Issues

I seem to be having the strangest LTE / 4G signal issues with the S4. I get 4G fine but when i leave a 4G area it drops to H+ or if the signal on 4G is weak it drops to H / H+ during this transition i am left without any signal for seconds to minutes as it switches.
Is there any way to find out what my LTE modem version is as i know my GSM one?
I am not too sure if this switch is normal to be lost without signal as GSM > H > H+ works fine and i still have signal

Check your baseband version and try to flash through ODIN the right one for your location

how do i do this? i can only see GSM modem not LTE. i know both versions maybe different

Mate the baseband of your phone is the same for both the gsm and lte configurations of your phone. If that won't work you can still check your carriers vpn configurations to see if there are correct

i just searched forums :

**If you are having the old bootloader XXUB flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1.tar file with odin by selecting phone.
**If you are having the new bootloader XXUD flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUEMJ5.tar file with odin by selecting phone.
So this means that even if it says the LTE modem is different to the GSM modem you are saying that the help about the modem for GSM and LTE is in fact the same?

From my knowledge you cant flash anything you like.You need to flash the correct modem for your region.Whats the version of your bootloader and your country so i can link you the correct file

I am experiencing the same thing, the switch from H+ to 4G doesn't drop the actual signal from the network whereas from 4G to H+ the signal drops leaving me no service at all for a few seconds.
I am starting to think that this is the normal behavior because it's like this since I got the S4. Oh and I have the latest modem for my country as well if that helps.
Perhaps someone with knowledge on how the modem works can chime in?

Thanks chickentuna for your reply
Ok the 4G works perfectly fine in Hong Kong, London but as soon as i leave london and go to areas with 4G but low signal, i get the horrible loss of network until the phone does a search. I think its more network / phone related but would just need to learn to disable 4G out of the main cities.
asbanoglou thanks for trying you can flash any modem but whether or not it will work is another matter. I understand bootloader, different modems and csc i am looking for something a little more non generic. I first assumed this was the firmware / modem combo but after trying multiple ones this does not seem to be the case unless there is a long standing issue with the S4 and LTE.
As a future note to get the modem versions you dial *#1234# . More > About does not give you the full picture but thanks for those who tried to help

I can't use 3G/4G in my On5 G550T2, it's only using 2G

Whenever I switch to 3G only, my SIM Card signals go down and when I search for network operators, none of the operators are found. I'm living in Pakistan and my area is 3G/4G granted and my SIM Card is also 3G/4G but whenever I keep it to Auto, my signals come back and my phone runs 2G or E instead of 3G. It used to run 3G before but when I installed the latest firmware on my device using Odin, it never switches or finds 3G operators or network. I didn't remember the version of the old firmware installed. Can anyone help me?
I have searched the whole internet but none of the fixes are working.

What firmware did you flash in Odin? Was it the latest firmware for the g550t2 and for your country?
