i tried to connect with the network operator telling me that there is no problem with connection the problem is in the phone

Not in this topic I had written. But as I wrote something that could help it - maybe you should do factory reset ??

Region?
Did you obtain the working handset from the same nation as the handset with the problem?
Which nation are you trying to connect from?

I'm having the same issue but, for what it seems, it should be a config file... try posting the question in the Ace-i's forum.. at least it's the same family model as the Ace-M (which I also own).
Maybe it has to do with CSC...

already post question but no one answered it

In case anyone is facing this issue, I resolved it by flashing an S5830C's NVRAM, it has to do with the NVRAM which contains the actual baseband (800/900/1800/1900 etc..), you can find it in the Bootloader package:

Hi, the file is in 7z because it's a whole firmware, but to fix the 3g issue in a S5830C/M you must use ONLY the Bootloader part of the flash, you'll know it because the tar part corresponding to it, has a file inside named like "HEDGE_NVRAM" and something else :silly: make sure to use the PIT corresponding to the cooperve, which you can find in the tutorial by @feetsonfire about how to recover from a brick.
Try first with Odin V3 1.84 if it doesn't work, try it with Odin V3 3.07.
There is no need for doing anything else! No recovery nor anything else related to it, just what I exposed in my post!

Worse and worse modems?

Hi guys,
I was wondering if you encounter the same problems like I do.
Long story short(er):
I own a I9505, with an LTE contract. Over time, and especially once moving to KK, the stability of LTE connection got worse and worse. And there are two problems: instead LTE I have EDGE or worse connection most of the time (the area where I work should have very good network coverage) AND even if appears as connected, internet is not working.
I have tried several (the most important ROMs), the problem is the same. I have tried with the recommended modems (at the moment of install). Finally, I have even switched back to the original ROM for my country. I can say that this was the worse experience of all, basically could not connect to LTE.
So, anyone encountered the same issues?

I feel the same.
I recently flashed the NZ stock firmware via Odin and the NC6 modem that comes with it is terrible!!
I now regularly lose signal and data.

As a mention, this is due to the fact that before the current custom ROM I have installed the official firmware for my country.

The normal is that u flash the ROM at the country of ur phone. No of ur country. You have remains of older firmwares there. Is normal that ur phone will be crazy.
1. Make a backup of ur Internal Memory
2. Make a factory reset (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Conect it to Kies 3
4. Kies 3 will give u the info you need for know ur correct CSC. This will be btw parenthesis close CSC.
5. Knowing ur CSC, take a look for this firmware in Sammobile.com
6. Download and flash it with ODIN (Dont flash a "Black EDITION" if ur phone isnt it)
7. Dial *#1234# again and take a look if u have the same what Sammobile was telling you. If not, flash again the firmware. (Example in pic attached)

Will try that once I get home. As I knew that Black and normal edition only differ on the look... the official one that I flashed was indeed the Black.
All you say makes perfectly sense...

It worked. Up to a point.
I have installed the official firmware and it looked like it was supposed to.
But, as I installed the custom ROM, both CP and CSC file have been modified/changed. So incompatibility still there.
More findings:
if I go in the service menu with *#2263#, if I chose 3G, there is no connection to the network (strange, as I am in the middle of the city, bu tnot unusual). but if I connect to LTE, i cannot make calls anymore. If I choose the mix 3G/LTE, once the LTE signal is lost, it gets back very slow, even if I am back in a zone where there definitely is signal. Basically, if I am on the stairs ro underground parking, lte is lost, 2g is on, and I don't get back lte once I am in the office (or on the street). i MIGHT get it when I change cells....but not a rule.

Your digging around has misled you. The GT-I9505 has 2100MHz support for 3g, as noted here, here, and here. It also has 2100MHz support for LTE. So something else is causing your issue. Are you certain your phone isn't in fact getting an LTE signal instead of 3G?

So in my country all service providers work with 3g at 2100 frequency, why does my s4 doesn't connect to 3g?
Well... sadly after digging around i found out that the phone doesn't support 2100 frequency.
It's the official firmware for this country, was bought in this country but only gets 2g and 4g
any way to solve this mess? most of the data signal comes from 3g signal, if i'm inside of a building i only have gsm data :crying:

i flashed a new firware from sammobile
so... as i search for 3g, only show vodafone, not the network that i need, the phone is locked to NOS. Also should show MEO 3g, and doesn't.
Strephon Alkhalikoi impossible to make that mistake, inside any building with another s4 i get 3g fine
Inside the buildings there is no 4g cover, i really need the 3g

Based upon the information you've provided, you're on the Baltic Black Edition firmware (CSC SEB). The firmware here though doesn't appear to be the problem. The problem is that you need to clear up some confusion here. You're saying you can't get LTE, are using unbranded firmware, yet your phone is locked to a carrier.
In an attempt to clear up things, please provide us with the missing information below, and confirm any already provided information is correct.
1. Model Number
Answer: GT-I9505, based upon the title of the thread.
2. Android Version, found by going to Settings > More > About device.
Answer: 4.4.2, based upon the firmware information.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing and running Phone Info from the Play Store.
Answer: AP and CP I9505XXUGNJ8, CSC I9505YXXGNK1, which using the sammobile.com firmware checker links to the Baltic Black Edition firmware.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Answer: No, if you're able to pull up the firmware version via *#1234#.

You seem extremely knowledgable on this subject, would you mind if i picked your brain ???? Ive been having a similar problem:

NOS (formerly PT Multimedia, ZON Multimedia and ZON Optimus). You will have to flash the latest firmware for your locked device. Download, unzip and flash this firmware via ODIN: HERE.

thanks but as i said before, i've tried many stock firmware, including that... that was te first one because i also thought that was something related to simlock
i will send the phone to warranty, or try at least

@Joku1981: If I didn't have to work today I would have told him the same thing.
@monteiro-ribas: If you intend on having the phone swapped out, you might want to flash the correct firmware that Joku1981 provided the link to before sending the phone in. I do hope you let us know if you get your issue resolved and whether it actually was the phone or, alternatively, the service.

My original post in modems:
Ok guys, my kingdom for a solution, please !!!
Here's the deal, I have a samsung galaxy S4 GT-I9505 bought in hong kong, worked flawlessly for over a year on Telcel Mexico network, took a trip overseas to France bought a sim put it in the phone, worked great !!!!, came home put in my original sim and since then my S4 has been unable to maintain a stable 3g connection, usually connects for a under a minute and reverts back to edge. I've tried many different things recommended on this and other forums:
1.- removing/replacing sim card
2.- removing/replacing battery for over 4 hrs
3.- tried different sim cards from different carriers with same result
4.- wipe and clean install with different firmwares
5.- installed cyanogenmod latest
6.- under network modes, tried selecting every combination of lte, 3g, 2g, automatic network registration and selecting my preferred network.
7.- tried flashing over 30 different modems
8.- flashed latest firmware from sammobile specific to my phone (I9505ZHUFNL1_I9505ZZHFNL1_TGY)
9.- took it to a "technician" and he managed to return my phone in the exact same condition with the exception that now the wifi didnt work (i managed to fix this on my own)
10.- installed advanced signal status from play store which gave acces to other goodies such as selecting radio band between automatic, europe and usa, tried everyone of them with no solution.
Tried to be as thorough as possible, hope someone out there has a solution. I thank you all for your time and experience. Happy Holidays !!!!! I hope I am posting in the correct area, i searched and found this is the place where my problem seems to be discussed
P.D. Since im flashing GPE right now the screenshots no longer reflect what im on but I do have a nandroid back up of this rom and I am about to restore it.
Hope I was thorough, thanks for any help

Downloaded SRS tool from another link which finally gave me access to Samsung Remote Unlock Client, followed the steps in the guide, used the file provided in this guide and everything seems to be working for now, gonna test for a couple of days and will update.
I have attached the files I successfully used. Great many thanks to the OP and to the 123unlock team, had this problem for over a month and fingers crossed this appears to have solved it. THANKS

it worked

desperately in need of help s4 i337m no sound can't call etc

Hi everyone I've been lurking around the forums the past week trying to find a fix to my problem and I just find anything that will fix it. I'm hoping one of you that has a bit more experience with this can help me.
OK so here's my problem
My Samsung galaxy s4 i337m was rooted but I wanted to unroot to update cause I'm new to it and never used my root for anything
I looked around and downloaded a stock ROM and flashed it in with oden and I had no WiFi no sound couldn't make calls no videos so I tried flashing another custom ROM and it let's me use data and text but no calls no video no sound I usually only get 2-3 hours of down time here to look for a fix and I have been all this week but can't seem to work the problem out
Does anyone know how to fix this so I can call my kids again I'm not gonna be homeor anywhere close to a place to get a new phone for another month
And to sweeten the deal I'll send 25$ PayPal to the person that can get this fixed for me
Thanks for your time

1. It's the correct firmware for your device and the latest. Yes. Problem of sound/wifi are related to wrong baseband normally. Reflashing it 2 times solve the problem.
2. We will try other options.
3. You have to install STOCK ROM for dial *#1234# first.

1. Go to Settings - Connections (TAB) - More Networks - Mobile Networks - Access Point Names (APN).
2. Take a look: HERE or HERE.
3. Reboot your device when you finish of add that settings.
4. You will have the data back

No signal [FIXED]

The problem got fixed a year ago.
The problem was the hardware and not the software
I've replaced the corrupt phone.

how you changed csc as u explained? usually flashing a diferent firmware with another csc will completly wipe the phone a d restore efs info, be sure ur flashing a different csc not included in the original csc pack (oxm and btu r the same csc for example).

maybe thats the problem, ILO and CEL r both the same CSC (OXM), if you dont flash other CSC it will not completly wipe the efs carpet, try downloading BVO from sammobile and flash it.
before flashing twrp or anyyhing first try your signal with completly stock BVO.

is wifi working ok?
had problems with my first s8 regarding gsm/wifi signal, got it exchanged to get it to work(it was stock untouched)

I will try this out, even though i did deleted the efs folder using odin(Checkbox EFS Clear) and even nand erase all.
Pretty sure it wont work cuz i live in israel, but i will try anyway.

after a full clean flash of the official firmware go to factory reset from the phone settings, if that doesnt work im out of ideas, but after a clean flash, do all the process without the sim card and put it after the factory reset

After a minute without doing anything suddenly, my signal is back but it crashes every time i use it like to answer a call, i guess my antenna is defect, i will return my phone for a replacement.

Hi, have you been able to solve the problem? It happens exactly the same

Yes i have a similar problem, apps crash, phone lags all the time. I use 2 bluetooth devices connected all the time, location is always open, nfc is disabled, i use nova launcher prime. Phone is not rooted. Call drops when there is no reason. Cellular signals complete goes away even though it was at full service a moment ago, then after 10-15 seconds, it comes back again. This phone is making me really sick. I was using galaxy s5 before this and it had a better performance than this one. I have galaxy s8 g950f by the way.
