Did you recive an OTA or you just flash a firmware?, im asking this since i got a similar problem, as a matter of fact i still got it but ive manage to fix by simple restaring the phone.
I flash a rom from rusia and i live in central america i was having problems with my 3g it was just not getting any data but if i switched to Edge if will work correctly, so i read some place that it could be a modem problem, so i downloaded and flashed a diferent rom, the problem kinda got fixed but i need to restart the phone in order to the 3g to work correctly, so u can just get another rom to try with a diferent modem.

The problem with mine is that I can recieve data but the thing is the signal disconnects by itself the starts back on again. I updated OTA.

[Q] Update probem

Hello guys,
I have been trying to update my phone OTA. I am able to download the update but when I click "restart&install" it goes to installing mode and at the middle of the process it goes crashing and there is no update. I have tried this 8 times since March.
What do you think would be the problem ? btw, I am using T-mobile version (US).
Thank you

[Q] Has anyone had problems with Android Wear after upgrading to a 5.0 rom?

This has been mentioned somewhere else before but I haven't found a reliable solution .... after upgrading to stock 5.0 (SM-N9005, tried both saudi arabia and poland rom), my LG G Watch R keeps getting disconnected. More accurately, it disconnects when out of range and refuses to reconnect when back in range. Only rebooting the phone lets it connect again. This is extremely frustrating and it's a problem that seems to be localized to the Note 3. I'm considering downgrading back to kitkat (but I'm not even sure how to go about doing that). Anyone know of a solution?

So solution yet, but workaround.
Thanks for replying. Sorry I didnt notice that thread before posting. The only workarounds seem to be using a BT autoconnect app which drains battery or else flashing a 16GB Hong Kong rom with pit file. I had tried doing that recently and ran into all sorts of problems and almost bricked my phone. I was lucky to recover from it. I may have perhaps used the wrong pit file or something, but in any case there's no way I'm trying that again. Can anyone point me towards a quick guide to downgrading back to kitkat? Is it a simple matter of flashing a stock kitkat rom, or will that cause problems?
had this issue on CM11

After installing the Poland ROM it was great. I had no issue.

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?

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

Flash custom kernel...
I try hadeskernel but is not working...but with india latest mm is working fine is the only rom with no bugs for me,but not have my language.
I want to fix bug to working fine wifi with my country rom but I try everything for fixing..
I'm couriosly if this bug is only for me..
We recently got a new VM router and I've been having WiFi problems with my SM-J500FN (2015): Not exceeding download speeds more than 4 Mbps. I hear many others cant get no more than 4 mbps on their J5.
Nothing seemed to change the speed. Wipe cache partition only solved it just for about a minute. Keeping the phone in flight mode with Wi-Fi on does solve this problem but you won't be able to take/make any calls.
Fiddling around with the phone, I decided to turn Android Beam off to see if that would change anything. After that I did a speed test and got a stable 56 Mbps. This seemed to do the trick for me. It hasn't dropped back to 4 mbps since. I did the same thing on my gf's J5 (same model, same problem) and it fixed it as well.
Go to: Settings 》 NYC and payment 》 Android Beam
Now, if NYC is turned off turn it on just to switch Android Beam off.
I don't know what makes Android Beam interfere with Wi-Fi reception on the J5 but someone might be able to explain.
Not sure but this may help with the J5 (2016) too. It's worth a try.
