Purchased new?

I am having the same problem. I'm on the May 30 2019 Nightly. I am original owner of phone. Clean install of LOS. Has anyone found answer? i thought it would be like a power saving or mobile network setting but i dont seem to see it.

No fix currently

I have had the same issue with all LOS based roms. I'm running 15.1. Restoring EFS partition from stock 6.0.1 QL1 does not fix it nor does re-flashing QL1 firmware.

[Q] My phone is unable to catch signals after downtime.

So recently in our area cellular services are blocked from time to time due to security measures. Now the really annoying thing is that my phone does not automatically catch signals when the service is back and when I reboot they are back. I have tried switching back and forth from airplane mode but to no avail it just needs a reboot. Infact yesterday when the services were back my data connection started working but there were no signals in the status bar and I couldnt make a call.
What could be the problem? I am running rooted stock rom 4.1.2 with matrix kernel. Or is this possibly a problem with the cellular company?
What version nexus s do you have? What radio is running?

Its the i9023. Radio I dont know but I have never fiddled with this stuff so I suppose its stock radio. Only think I have done is root and custom kernel.
I used to have this problem, wanna know what happenned? My NS died (hard brick).
Most likely won't happen to yours.
The solution might be to flash a new radio that is compatible with the i9023. Radio's can alter your network performance and signal quality. If you're interested, here is a thread with different radio's:http://forum.xda-developers.com/showthread.php?t=1116884. Remember to always backup before flashing, and you can revert to your old radio by flashing it. To check your current radio, go to setting-->about phone, and look for baseband version.
An alternative is to try to flash a new rom, if you dont want to flash a radio.
Another alternative is a factory reset.
BUT, there is a possibility that our phones are designed like that, and none of these solutions will work.
Good luck! keep me updated
I have the KI1 radio. Well I asked a friend with an Iphone 4 and he says it "sometimes" happens with his phone as well so I suppose it's not something completely abnormal.
I don't actually have any signal problem apart from this issue. I never have to restart phone to get signals unless this specific timed ban on cellular services happen, I don't lose signals with some regular very short problem with network. I suppose it's just better to live with it than flashing new radios?
I might flash a custom rom soon so the factory reset solution will be tested then.
Did your Nexus S just randomly died? How do you suppose it had something to do with this problem?

I don't think it has to do with the problem, but i never found a solution because it died. Let me know how the new rom goes!

Also, a radio flash isn't that bad, but if it's out of your comfort area, that's cool

Btw there was also another problem that I didnt mention. Sometimes my phone refuses to turn on data connection and it only comes back with a reboot. This ONLY happens very rarely when I switch from wifi to data and never happens after data connection has started.
Did you have this problem? I just switched to CM10 yesterday and it has once happened so far but its not related to the ROM since it very rarely happened before as well.
I actually did have this problem! With my old ns. How long have you had this phone?

Its about 6 months old. I am experiencing this problem more whenever wifi is on for an extended period, so far I have had it 3 times with CM10.
I went back and forth to airplane mode and it started working so atleast didnt need to reboot.
I think this could be a 4.1.2 problem for me as I dont remember this happening previously.
Maybe try an ICS ROM?

well it's was fun, but i give up..

i've tried to re-flash the rom with the T699UVBMC5_T699TMBBMC5_T699UVBMC5_HOME.tar.md5 and although it seemed to working fine, (internet access etc.) i just can't dial with it anymore (while i can do that with another phone with the same sim) , add to that, the strange wifi connectivity issue i've been getting (as in hopping back and forth between roaming data and my access point) , the sluggish behavior i keep getting along with the extended battery reaching 45 deg Celsius (might be all the bloatware i couldn't remove), and now i can't even find another one (unlocked) in ebay.
just too much, the glide i have still works well sort of..

Through Kies, do a firmware upgrade and initialization.
But it's already version 4.1.2

So it is huge chance it is hardware problem.
If I were you, i would again do flash with T-mobile firmware, but before clean everything.
you mean stock rom? how can i do that?
well i found the stock rom here, http://samsung-updates.com/device/?id=SGH-T699 flashed it, and the phone works, but now, the wi-fi doesn't, i mean when i turn it on, it simply turns itself off again.

Firstly it is not official Samsung site.
Try to do hard reset and then update over the air.
well something must have worked.

eventually i ended up upgrading use kies, that solved the issue with wi-fi (well sort of, i noticed that at least at home, i somtimes see BOTH wifi and 4g icon, like it can't decide which network to use) ,and still able to dial .
so now i have an operational phone, and back to square 2, meaning how can i root with a CWM that blocks all files with signature verification failure.

[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.

Nexus 5 stuck on "Turning wifi on"

Hello all, my old Nexus 5's wifi stopped working back in January for no apparent reason. Everytime I tried turning it on for some strange reason it just Grey's out. The MAC Address is also really weird. I tried looking for a solution but to no avail. I'm starting to think that it's a hardware issue. These are what I've done so far for the past 4 months or so:
- rebooted the phone
- wiped the cache
- wiped data using TWRP
- letting the battery drain and charging it again after a couple weeks
- smacking the back side on my hand (lightly of course)
Any help would be much appreciated. Also, it's not my primary phone anymore so I can't tell whether cellular connection would be working or not.
Just did a factory reset and wiped everything, still nothing. MAC Address is just a solid 2.00.000.00. Also, Bluetooth still works.
Try running a stock 4.4 or 5.01 rom. If the problem still exists, I'd say it's a hardware issue.

Still doesn't work for me. I'm gonna try taking apart the phone to see if the wifi chip is ok, hopefully it's not a hardware issue.
Same problem here, even on custom ROMs and factory images,
Is there any hardware solution? Maybe an external WiFi antenna or something like that?

Not that I know of unfortunately. Guess we'll have to buy a new Mobo for the phone
Hi guys! Since today I hopped on the "activating wifi" train too!
I'm on Lineage 14.1 CAF, and did a full wipe and flash, no changes.
I followed a guide in a post here on XDA to recreate the MAC address file, after that wifi worked for a couple of minutes, then went down again.
I thought about flashing MM stock image, but after reading your posts I think i'll keep my phone this way until I buy an OP6.
Luckily I have 15Gb of cellular data
What I did was I opened the phone and took out the motherboard and disconnected the battery from everything, then took out the heatsink that's on top of the wifi chip. It worked for a bit then it stopped working for good. It definitely has to be a software issue because Bluetooth is working fine.
It could be a hardware problem. I have two Nexus 5 motherboards where the wifi tries to turn on and, eventually, the slider goes back to the off position.

Damn, I guess I'll have to change the motherboard to get it working again. I might just sell it as is or for parts since it hasn't been my main phone for a while. But I did want to give it to my nephew...

MY Nexus5 got the same problem WiFi just stopped working suddenly. The mac got some stupid address like 2.00.00.00. I tried every thing still nothing. I have already rooted my nexus so tried different roms but issue still remains.
Then i just remembered about the ROM UBUNTU Touch i have installed it and WiFi in Ubuntu start working again with original mac address. I am currently using Ubuntu touch and didn't try to reinstall the android rom again.if some one try this and got WiFi working like me please inform me that if the WiFi still works if i reinstall android system.
If you want to download Ubuntu touch download it from ubports

Hi guys i have tested as mentioned before and reinstalled stock room after installing ubuntu my WiFi is working again perfectly :fingers-crossed::fingers-crossed: . Who has the problem of this kind should try doing this method it will reinsert or reset the mac address and get rid of the problem of the mac address of 2.00.00.00.00. and your original mac address will be restored. It worked for me hope it can help you also
