Hello guys ,
Help me out , i got as the Title states a problem , is when I switch from 3g (GSM/UMTS) to 4g ( LTE/CDMA) , i see this red X over signals , along with No mobile network when trying to use Phone Dialer .
The bands Used by my Network are : 900/1800 MHZ .
Btw, When i select 3g under Preferred network mode , everything Works fine , including VOICE&DATA !
Current Build ; NG2
Previously Phone was running on Some Custom i9500 rom , i dont know how Despite of Being SPH-L720 , then i flashed the original Stock Android 4.4.2 , Everything seems to be working fine , except the problem stated above and Also i dont see Any sprint logo , which i think i should be seeing as it is Sprint SPHL720 . I haven't upgraded to Lollipop , as i want this problem to be solved here .
I need some info and stuck kinda here. Experts opinion and senior mods attention is direly seeked.

Hi guys !
I've just bought a samsung galaxy s4 (i9505) (a used one not new) and i flashed Imperium v7 and modem GNF1 and bootloader GNF1 (initially the phone was on stock 4.2.2 and the problem was already there).
My problem is that i don't get the network i rarely see two or three bars but it directly goes to zero (i can see the no network sign) and stays like that until a reboot (as said it drops to no network very fast).
So my question, is it software ? (should i flash the latest samsung stock firmware ?) or is it hardware ? (replace the internal network ship ?)
Or is it a common problem on S4 i9505 and no solution cannot be found ? :crying:
Could it be related to CSC ?
Anyway, i hope anybody can help me because i really like this phone and the rom that i just installed ..
Feel free to ask me about additional informations.
EDIT : I already tried :
1) the modem+bl FNDA => same result
2) force the phone to gsm only => same result (maybe better but even it solves the problem there is no point to not having 3g activated all the time)

It's going to be pretty difficult to narrow this down with what you've posted. You say the problem was "already there" when you got the phone -- how long did you use it on the stock 4.2.2 rom before flashing a new one? Did you see exactly the same behavior before you started mucking with it?
Hi ! Finally an answer So i used it for about 3 days and i really can tell that it is the same behaviour
My fear is that it may be related to hardware .. I am gonna try to flash the latest samsung stock firmware (with its csc and modem) ?
Anyway any idea ??

In general I'd say it's worth getting the phone to "current" stock, or as close to it as possible, and seeing what kind of situation you're in (i.e. if the behavior disappears or changes in any way). If you're seeing it on every configuration, it seems reasonable to suspect that it could be a hardware issue -- especially given that you got the phone used.
Perhaps someone else knows of a more definitive test you can try.
Hey ! Thanks for the idea ! already flashed the latest samsung firmware and same problem .. i stayed in touch with the guy that sold it to me so he took it back to samsung sav where his friend (who work there) told him that this is a famous bug in the i9505 4g serie and that the only solution is a
nvm restore (something like that). Of course he'll do it for free cause we agreed that if a problem come out he'll have to solve it on his own.
Anyway, i hope to get it back tomorrow or monday ! I'll let you know what happened as soon as i get it back !
solution?
Were you able to solve the problem? in case u were, how? i have the same issue sometimes i have 3g network, then it goes to gprs then edge, sometimes when im connected to wifi i cant receive calls, but i can do calls, any idea?
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???????
Hi folks.
I recently bought a refurbished S5 G900H , INDIA
it came with pre-installed kitkat 4.4.2, but without using anything on the mobile i flashed a custom rom .
everything was fine until i discovered that there is a problem with the network .
whenever i try to switch network to WCDMA only i get a notification stating "NO SERVICE".
GSM mode works perfectly fine , i can make calls and use internet but with a slow speed,
the same SIM works absolutely fine with other phone with same network setting at the same location .
so i tried flashing all the stock FIRMWARE available for G900H INDIA from www.sammobile.com . but the issue is stll the same .
also tried flashing different modem available but no help .
some time i get a very weak 3G or H+ network but that too in a ground or open space but not in my home .
i have tried all the SIM from carriers available but the issue is still the same .
i can check my IMEI and baseband .
what else i can do ??
PLEASE HELP ?/:crying:
Strange signal issue
as the tittle speaking , im having a very very strange issue on my note 3 , when i use my main sim card , i get a very low signal ; i have even managed to change it , without any further results , i then decided to use another sim card from another carrier , then i got full signal bars , i have tried to factory reset my phone , but without any results , the only thing i didnt do is flashing my device as i dont want to use lolipop , as it is impossible to go back into an older stock firmware , by the way i did not root my device and im not looking into it , im still not sure if its a hardware issue or software , i am really confused , hope someone could help me
thank you in advance
EDIT : i forgot to mention that when i use my main sim card into another phone i get no problem at all .
EDIT 1 : Tiitle has changed on its own , i am not using a custom rom , and im running android stock 4.4.2 kitkat rom
Hey guys
I don't know where to start but here we go
last week i bought a used Samsung Galaxy Note 3 ! on the system it shows Note 3 N9005 , and there's also the option of 4G/LTE so i was convinced that this is a N9005
everything works fine ; but the network signal is so weak and it only show " E " instead of " H " or " 4G "
And this is really what made me mad : When i verified the IMEI on several websites it shows That it's " a Note 3 N900 " !!!!! i couldn't believe that
cuz on the system it's N9005 ! on the Recovery it shows N9005 ! when i flashed a rom on it I used The N9005 Rom and it works ! on the boot logo it shows N9005
Only on imei verification it shows N900
So please is there any help ! what should i do ?
Run Phone Info from Play Store.
I don't know how to post images
It's not allowed to post images from an url
cuz this is my first post here
But on the app it shows N9005 also and everything is fine
i just can't understand
Weak Network >> Wrong Modem or Wrong settings /Wrong CSC .
IMEI wrong reads like its a stolen phone with a cloned IMEI .
Are you sure you have checked all in Phone Info .
Yeah everything in the app looks fine as a N9005
I tried even more apps wich shows informations about CPU and GPU and it shows the configuration that exist in N9005 not in N900
But whenever i check the imei it shows that this phone is N900 !!!!
I flashed it with several ROMs custum and official ! But nothing changes
Too weak network , it shows only "E"
My brother has the same model "Note 3 N9005" and he has no problem with network : 4G works like a charm ( we are on the same floor) so the problem is not from the network provider
Could you please tell how to change the modem or the CSC or whatever !! I really apreciate your help

is the IMEI at the back under the battery is the same as in About Phone or *#06#?
but i'm suspecting something wrong with your antenna... or you can try *#2263# and change to LTE only
and please do hard format i.e clear data & cache in recovery before and after flash for best result.
Your phone probably has been injected with superimei number. You need to find a repair shop that can rebuild your imei number (or a working superimei number).
