[Q] No 3G after PDA+PHONE change - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I bought my Galaxy S4 from Colombia about 6 months ago.
Yesterday I was trying to change the PDA + PHONE with some other Samsung original rom and after the phone rebooted there was no 3G signal.
I tried to do Factory reset, and change APNs.
How can I fix that?
Thanks for your help!

1. Install Kies 3 for know ur CSC (pic 1). Go to Sammobile.com and download the latest firmware (correct CSC) for your device.
2. Flash again this firmware and let the process finish till the final. Dial again *#1234# and verify if all is correct like the firmware you downloaded and installed before. Reflash again same firmware if not.

I think that I might also changed the CSC with the Odin.
What should I do in this case?

[Q] Galaxy S5 Locked Vodafone WiFi settings

Hi all,
I bought an S5 that had been locked to Vodafone. I have had it unlocked and flashed it with the UK generic software to remove all of the Voda bloatware. This is all fine but unfortunately it still has the Vodafone WiFi settings in it meaning every time I am on the underground it tries to connect to the WiFi under Vodafone, when I have looked there is no option to forget (remove) the Vodafone settings. I flashed the phone using Odin and followed the guide and used the firmware supplied by Sammobile.
Any help would be greatly appreciated.
Thanks,
Matt
Hi. I have an unlocked Vodafone one I picked up today. Can I ask what CSC you flashed in Odin and died it trip Knox?
Flashing firmware doesn't routinely remove userdata settings. Do a factory data reset from the settings menu and that should resolve your issue. Be sure to backup any files that are important to you first though.
In the alternative, you might be able to reset just the wifi settings by going to the Application mamager in the settings menu and see if you can identify which is the wifi app. If you can, then clear cache and data from the tab for the wifi app.

Flashed mine with BTU tonight. It didn't stick properly the first time and using an app called Phone Info, it said the active CSC was VOD/BTU. I need to factory reset and reflash a few times before it fully applied the new CSC.
Maybe yours is VOD/BTU?

[Q] S4 Problem with network WCDMA (3g)

Hi all, I have a problem with 3g.
I bought s4 i9505 and it was on 4.2, I had problem with slow internet, so I called operator and they told me to turn on WCDMA only in settings..

Might be a corrupted EFS folder.
I have had the same problem for 3 weeks now. I've tried searching for a solution here and in other online sites to no avail. I personally tried flashing a new stock rom, flashed some odd number of modems, tried factory resetting etc. Nothing worked. I'm afraid it might be due to corrupted EFS folder which I still don't know how to repair.

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?
monteiro-ribas said:
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:

so.... I9505XXUGNJ8/
csc I9505YXXGNK1
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

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)

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.
