Help with network signal loss - Galaxy S 4 Q&A, Help & Troubleshooting

2 S4. Both running the same rom. Both running the same kernel. Both have the latest firmware (according to sammobile). They are both International versions.
The only difference is: One was bought from Germany and one from Romania. The German S4 belongs to a friend. The other one is mine.
The problem started this morning-noon. Last night, around 8 PM, I flashed the latest GPE build by Danvdh, with the latest Googy-Max kernel on both devices.
They both worked fine since first boot. But the German S4 started acting up today. It randomly lost network signal.
My S4 works fine. Haven't lost signal or anything.
I can't explain why this happens. Or why it didn't happen until today, around noon.
Someone in the rom thread suggested it might be a firmware/modem issue.
Well.. Firstly: It worked fine with previous builds.
Secondly: Why would it work during the night but in the morning it fails?
Thirdly: It already has the latest firmware..
I thought about a re-flashing the rom. But not until I hear some more opinions

[Q] Updated to MJ7, network problem

Hi,
Bought an N9005 3 weeks ago. It used to work fine. Last week I updated the firmware to XXUDMJ7 OTA. Interesting enough, the modem/baseband got also updated to XXUDMJ7 (from MJ3 if I remember correctly). The weird thing SamMobile doesn't have an MJ7 firmware with MJ7 CSC.
Anyhow, since the update last week, I started to get funny error "Not registered on network" every few hours. Apparently, if I go to indoor with weak signal area then go back to outdoor, the phone shows this error. It won't register back to the network.
Has anyone experienced the same problem?
Any idea how to solve it?
Cheers,
Abdul

[FIXED] [S4 I9505] I have to update modem to fix CM11 issue, but there's no update.

Issue fixed. Updated to XXUGNG8.
Issue: network disconnects when I lock my screen, which results a phone being useless a brick on sleep.
Issue link: https://jira.cyanogenmod.org/browse/CYAN-5379
Solution: update firmware/modem/bootloader.
Solution issue: there's no available firmware update for my device.
Hey everybody,
You guys probably have heard that newer version of Cyanogenmod have issues with network. It seems like there's only way to fix it is updating modem and bootloader.
I have international i9505 with baseband of XXUAME2. I looked it up on Samsung firmware database and it turned out that it is for Russia and last update was in May 2013 and for Android 4.2.2.... the catch is that it's made for i9500. I don't know if it's a mistake or not, database said so.
I bought it last year from some sketchy shop for low, low price in Russia and phone was in french language and was made for french carrier. It doesn't matter because phone works perfectly fine and I wiped it clean by flashing it to Cyanogenmod.
Now recently I just moved to USA, using T-Mobile prepaid plan with my international I9505. There wasn't any issues using Russian baseband until Cyanogenmod updated.
I tried looking for USA T-Mobile baseband firmware for my device but there's nothing to be found. I tried looking for Russia's update for my device. Nothing found, just XXUAME2 that was last updated in May 2013.
How can I fix this new Cyanogenmod issue? People keep saying that updating their firmware fixed the issue, but I can't update my device. What should I do? Should I update to T-Mobile baseband if it's available?
Thanks a lot.
Issue fixed. Updated to XXUGNG8.

Galaxy S5 Plus (SM-G901F) losing mobile signal and gps after Marshmallow update

After updating to Android 6.0.1, the phone is randomly losing mobile and gps signal. It happens about 30-40 times a day, especially when moving around, like driving . Almost every time I look at my phone, I see "No service, network not found" or "gps lost" messages. After about 10 seconds, the signal comes back and everything is ok again. Very annoying and impossible to use navigation apps, like Waze and Google Maps. I have made a soft reset, a hard reset, wiped all data and cleared the phone cache, checked and cleaned the Sim card. Nothing helps. Before update the phone worked brilliantly. Also noticed, that the signal won't drop when using wifi, the problem occurs only when data connection is on. And I'm not the only one, I have 2 friends with the same phone and the same problem. Looks like a software issue. Can somebody help?
PS. I'm from Estonia, and the software version is G901FXXU1CPE1/G901FBAL1CPE1
Thank you in advance...
Hi mate,
I Have the same device although mine uses a custom ROM but the problem I experienced was exactly like yours
Samsung released a new issue of the 6.0.1 for our phone, PDA G901FXXU1CPF6 CSC G901FPHN1CPF2 you can login to the sammobile site and download it
As I said above I have a custom ROM so I only flashed the modem firmware from that release and worked fine after that!
Hope that will help you!
Thanks for your response! But I'm using a totally stock phone and I see, that this firmware is for Netherlands. Does it work on my phone or I have to wait until the Baltic version is released?

Hello,
I don't see any reason why it wouldn't work but just in case make a note of your Access point name settings in the mobile networks tab just to make sure that everything is the same after you flash the new release .
If you follow the steps as described in the sammobile site you won't have any problems.
What I have noticed however is that after I flashed the new modem firmware the mobile hotspot does not work anymore but this has to do with my custom ROM.
It worth trying though the performance of the phone after that is exceptional and the signal strength is higher than before and most importantly, doesn't crash anymore..
Let me know if you need help and keep me posted about your results!
i had that ROM for a while, didnt help in my case, still same issue. I'm currently on XXU1CPG3 with which the issue still persists, gonna try flashing the new TPD CSC ROM (currently the newest) ROM Version CPH9. My baseband is still CPE1, which do you guys have?

Baseband:
G901FXXU1CPE1, I have a totally stock phone with the latest official firmware.
Latest official firmware from where? ("latest" is region dependent)
Ok, the cph firmware updated the baseband to cph, on my side it's only been a while 14 hrs since flashing but it seems the signal problem is finally fixed

From what I understand it doesn't matter which ROM you are using the baseband is the one that causing this problem..
As I said I have a custom ROM and when I had the CPE1 baseband then I had all these problems.
If you flashed the ROM and your baseband is still CPE1 then something did not go per plan I think..
After flashing ONLY the modem firmware from the CPF6 release to my SMG901F is reported that the baseband version is CPG2 however..
This version works for sure..
I might try the CPH9 release now to see if the issues i have with the mobile hotspot will be solved

I'll try to install that CPH9 release too. Let's see what happens, because I have tried everything else.
To me it seems, that this CPE1 version is having problems with switching between network modes. I checked, that in Settings- Mobile networks- Network mode is set to LTE/3G/2G (automatic connect), but I haven't seen H+, H or Edge symbols on top of the screen. Only 4G/4G+ or no reception at all. Like it's locked in 4G network or something. And sometimes when there is no 4G network coverage, there is also no signal. But that is just my logic...
Ok, I flashed the latest CPH9 firmware and my baseband changed to CPH3. CSC Country turned to Netherlands instead of Baltic. And it seems that the issue is fixed!
I made a little test, I went to the cellar to get bad 4G reception and instead of showing No Service, 4G turned to H without losing the cell signal. Let's wait and see...
Thank you guys a lot for your help! :good:
Hi
1) I have the latest PHN version for SM-G901f stock& rooted. I see the TPD version, will it have dutch language if i flash it ( without wipe anything) in ODIN?
2) What does TPD stand for anyway?
I want to do this because i see TPD has latest security_patch sept 1
With rooted Phone there is no way (as far as i know (3) ) to get security updates without getting the message it as screenshot given under here....

Pliss help me with step to fix it
Hello! It seems all the firmwares ending with CPE1/CPH1 are problematic. You can try some other firmware from http://www.sammobile.com/firmwares/database/SM-G901F/
Select the firmware what seems best for you, don't select the operator-based ones, like vodafone etc. If you click on the firmware and scroll the page down, you will see step-by-step instructions how to install it. Good luck!
Ok but i can't found latest country band FW have same with indonesia network (except FW country singapure now i using it)
So i'll try to download FW update 2016-09-03
Country Unknown
Build date Tue, 13 Sep 2016

Hello.
I have a German unbranded device.
Since I did not want to wait for Samsung I installed the update myself by getting the already released version they seed in Italy since a few days.
Almost the same. Lte and German Sim card working, everything like if is supposed to. I think installing the Italian update is not a problem.
Works like a charm. Much faster then before. Some screens are following. I can recommend it to everyone that doesn't want to longer. St least for me there's is no problem.

Is a factory reset needed? Or can you keep all your apps and settings?

Is your device a T715 or T715Y? Does it even make any difference? I have a T715Y (imported from China, I think) and have downloaded the Nougat ROM (which is noted as being for T715 (but not specifically fore the T715Y) from Sammobile and tried installing it using Odin 3.12 but it fails. I also tried using Odin 3.11 which also fails. Both ran as Administrator.
Current ROM Build Number is T715YDXU2BPJ1
Can anyone give me some idea of where I might be going wrong?

I think you need a rom for your device (https://www.sammobile.com/firmwares/database/SM-T715Y/).
For me the update with the italian version worked great and I now have a german-austrian-italian S2 :laugh:
I have sm t 715 without y. Differences between the both devices I don't know but I'd suggest you wait until the proper firmware is release for your device. As far as I see there is no android 7 rolled out four your device.
Any ETA on Android 7.0 for the real SM-T715Y? Does anybody know anything?
I got the SM-T710 XSA Nougat update some time ago now. But I bought the 4G version off Gumtree and it is still stuck with 6.0.1 which means the lowlife carriers are probably halting the updates.
It is disgusting. With carrierless Samsung Galaxy smartphones, Samsung waits for the carriers in XSA region to start to release their crapware, before they release the official Samsung firmware. I do not know if this occurs in other regions.
FYI, the SM-T715Y is the real Tab S2. The SM-T715 has very few firmware regions and was probably made for dodgy countries with outdated cell towers. Look them up on sammobile.com/firmwares
Thanks people!

AQl7 Firmware

I was wondering if anyone has experienced issues with the latest AQl7 firmware? I've recently been experiencing random reboots on Renovate Note Port 1.1 ROM a couple of days after flashing the latest AQl7 firmware, could it be the reason or am I misunderstanding this?
Thanks for your time.
The latest firmware version for Verizon is AQI6 and I've had no issues since updating 2 days ago. I'm running on stock.

Thanks for your reply. I'm actually talking about AQl7 but I remembered it wrong. I'm currently running a different ROM on the same firmware and will see how it goes. If the random reboot happens again, then I'll probably downgrade the firmware to the previous one (AQH3).
