[Q] Connectivity problem, all roms?

Been using custom roms on my Inspire 4g since about March with no serious issues till this week. Sometime around wednesday, my connection to my google account, the connection to talk, market, gmail, etc. Seems to be dropping out and locking up my 4g connection for a minute or two. This is really annoying. I have tried numerous different radio and rom combinations as well as going to the store and getting a new phone. The only thing that keeps it up and running is if I roll back to stock. Any help would be greatly appreciated.
Have recently tested Absolution, CM7, Android Revolution, and TalonRom with recommended radios per developer instruction to no avail. But am up and running fine with roll back to att gingerbread update via hack kit...
Any suggestions?

I was experiencing loss of background data on both my inspire and my atrix with stock gingerbread, until just recently. The only conclusion I came to was that ATT had a problem, at least in my area, with background data staying connected on 4G phones running gingerbread, except on wifi. About a week and a half ago, I noticed that the problem had mysteriously resolved itself, and I was having no more issues with push to email and other apps. I can only assume it was something they fixed with a network solution. Perhaps this fix has caused a problem with the roms you're using. I know that numerous calls to customer service failed to produce an answer for my issues, it seemed either no one could figure it out, or it was a known issue that they weren't acknowledging.

Yes, similar to me. Thanks for the reply. I'll give a Rom a try over the weekend and see if the problem has rectified itself.

Nexus 5 WiFi problem

Hi guys, I am having a strange problem with my nexus 5, or I should say my Wife's Nexus 5. Right what is happening is that when my wife's phone is connected to a WiFi network it does not receive calls. My phone is identical and has no problems at all. The phone has been back to where we bought it from for repair twice and they finally gave us a brand new phone. After getting home and restoring my wife's phone it has the same problem. Both phones are stock and updated to 4.4.4 . I have checked the settings and as far as I can see they are identical. If I reboot the phone it will ring with WiFi on but after a couple of minutes the problem returns.
Now I would guess that an app is causing the problem but I have tried uninstalling and re installing most of her apps but still can't solve this. I have spent ages on the phone to our provider (T-Mobile UK) tried my sim in her phone but still have the same problem. Is there any type of diagnostic software or app I can run to try and pin point the problem?
The phone has been factory reset but still got the same problem! Bearing in mind the phone is brand new and has the same problem as the old one its got to be an app hasn't it, but how to work out which one
Thanks in advance

Well after an evening of uninstalling and re-installing apps and resetting it seems to have cured itself. I am sure it was something to do with the recent system update, as the problem only started recently. The phone is just over 6 months old and we have had no problems until this. Still fingers crossed it seems ok now.

Hi, i'm having the same problem!! When on wifi sometimes calls get through but most of the time it blocks them, I also thought it had to be something about an app but i even booted the phone into safemode which disables all 3rd party apps and the issue was still there. Where you being able to narrow it down to something in particular??
EDIT: Nevermind, i think i found a thread with the solution.

I should have updated ages ago, the problem was in fact being caused by the sim card. Dont know why it suddenly started playing up but it coincided with the software update to 4.4.4 But my phone was identical and had no problem and my wifes did. Compared to hers my sim was relatively new we eventually ordered a replacement sim and there has been no problem since
Sorry I could not be any more help

[Q] Data once lost wont re-connect

i am currently using Resurrection Remix 5.0.2 but was using cm12 nightlys before. The problem is that
the data connection is good but once i loose the connection there is an exclamation mark next to the
signal bar so i presume thats the data lost. It then wont connect again untill i reboot the phone.I have tried
switching on and off data but still no joy..This never happened on kitkat. I thought the problem was CM
related hence why i tried the RR rom but exactly the same is happening. Someone sugested that it could be
the sim card but im not so sure as it works fine before lollipop.I surely can't be the only one experiencing
this? but by the same token i can't find any info on it either ..maybe says something!!
Hope someone can help as i want to stay on lollipop i do like it, maybe the official release will sort it out.
Thank you

It's a ROM issue (radio.img). I was facing same problem on earlier builds of BlissPop ROM, but not no issues..
If you are getting exclamation mark in 2 or more ROMs, then there is problem with your sim-card or the network operator.
I suggest you to contact your concerned network operator and take his help for the same. (If you are facing same issue on 2 or more ROMs, try out Stock ROM CM11s)

Thank you for your reply, so would it be possible to flash a modem from kitkat or would there be compatibility issues with that?

did you check your network type and apn settings

So here is the latest update. I replaced the sim card on Saturday, the problem is is still there. I checked me APN settings they are three UK so that's ok. I've tried cm12,resurrection, blispop and now I'm on sabermod. I'm thinking this oneplus doesn't like lollipop, looks like I will have to revert to kitkat for just now until the official release comes out but I can't see that fixing the problem either as I don't seem to see anyone else with this problem.
Thank you for your help folks

I'm also with Three and have lost my data connection. They replaced the sim on Tuesday and I'm sure it worked until the old number swapped to the new sim. I have a 321 simcard on order and I'll try that once it arrives. My phone is still running Kitkat.

I had no problems with kitkat, if it lost the connection it automatically connected again when I was back in an area with a signal. But this has got me beat, a new sim card and too many roms to count but still the same problem. I am a lorry driver and cover the whole of Scotland and signal is patchy at best and it's annoying to find out later on in the day that data was off and you didn't receive any messages or emails.. Some of them important..

I have exactly the same problem.
I'm from Spain.
I've discovered that if i set network type to LTE it seems to work right.
Today I've moved from blisspop to temasek.
The 3g reconnect doesn't work, as always.
I turn data and wifi off when I sleep so tomorrow I will confirm if LTE works also with temasek.

my connection has always been set on LTE but never makes any difference
At the weekend I installed the official OxygenOs, I have been driving all day and had to reboot the phone 4 times because of this problem, I did half wish that when an official release came it would maybe sort out the problem but no joy. So I can only think it's to do with the oneplus. I'm at a loss now and seriously don't want to go back to kitkat but it looks like this will be the only solution to the problem..

I've tested this night again and if I set network to LTE.
The test I've done is.
- Turn off data and wifi before to sleep.
- Turn off only data when I woke up.
The connection was successful almost inmediately.

Greetings. I ran into similar issue with the CM12s update.
Once I lose the mobile signal for whatever reason, the data connection is not restored. Only way to regain it, is by restarting the phone (haven't tested airplane mode). Sometimes even if I leave WiFi on for long time (overnight), I will not have data connection after turning off the WiFi. I use HSPA connection only, not LTE.
I can not recall having this issue on KitKat. Issue was on the first CM12s update and remains on the second one, both were installed clean, so clean install of the ROM will not fix it. I am not using any custom ROMs or kernels, only TWRP recovery.
Has anyone had such issue and maybe found a solution to this?

Did you ever get this sorted? I've been having this issue, luckily I always have Wi-Fi at home/uni but there are times when it just won't find a Data connection. This happened right after the CM12 update :/

Well decided to a bit of searching, if you go into Settings -> Mobile Network Settings -> Network Operators and manually choose the network rather than the Auto Search option, it seems to have worked for me for the time being.

I am on the same boat as OP. The problems started after updating to Lollipop.
If anyone has found a solution, please let me know. I read about someone installing a 44S modem, but I'm unsure if this will permanently change system files (I wouldn't want it to) and I'm therefore hesitant.

[SOLVED] Phone Doesn't Automatically Regain Data Connection

Hi guys, I am currently experiencing a very annoying problem on my OnePlus One. If I go to a place with bad reception or no mobile data available, my phone won't automatically get connection on good reception area before I reboot it.
Let's say I have good signal strength and working mobile data on my room, but my kitchen has bad signal strength and no mobile data. If I went to the kitchen and let the phone loses reception and mobile data, then go back to my room, my phone will have no reception and no mobile data unless I reboot it. Usually I can just turn on Airplane mode and turn it off so my phone can reinitialize the reception but not anymore.
I noticed this problem since I flashed Cyanogenmod Snapshot 13.0-20160819 (ZNH5YAO0IN). This problem is very annoying especially when I am outside because I often found myself missing lots of Whatsapp texts since I don't realize my phone doesn't have any mobile data.
What do you suggest to fix this problem? Any help is appreciated.

Try changing rom?... We have lots of good Nougat ROMs.
You can flash a new modem, go through the one plus one sections.Only if you're rooted.
Else you try formatting the phone, obviously with data backup.
Hope it'll help. Thanks

This is a fairly common problem with the OnePlus One. It's caused by the modem version you're on. For some (including myself), the problem can be fixed by flashing the c7 modem vs the older c6 ones. But, do be warned, for some this wipes out all radios on your device (Bluetooth, wifi, LTE, etc. all break). So before you try flashing new modems, make sure you have a copy of the one your phone currently has so you can flash it in the event that your radios stop working. (I want to say a nandroid backup doesn't actually save/restore the modem firmware). Do some googling in that direction. Might just lead to a fix.

Pardon my lack of knowledge with modems, but which one from this thread can I flash? I see some marked as H20 or Oxygen update, are they tied to that specific ROM or will they work on any ROM?

They're not ROM specific. They're device specific. You'll just want to try the c7-13 one, I'm guessing. Just keep in mind the cautions I said previously.

I saw a fellow member on the same country as me flashing the C7-11 (latest available on Modem Collection thread) and it worked for him so I figured I might give it a try. So far so good, not a single problem. But hey, thanks very much for pointing me to the right direction! I was close to change my ROM and wipe everything.
Edit: 5 days passed, not a single problem encountered. Suggested fix is proven.

Help , Mobile data not working with custom rom

So I tried pixel experience a while ago and it was all fine but mobile data wasn't working who worked normally when I was using Xiaomi's ROM. So I searched some posts up and saw people switching to Evo X so I tried and it all went fine but internet wasn't working here either. I've made sure I have data and internet enabled and stuff but it just won't come up at all. Anyone know how I should resolve this issue?
