[Q] No service on Galaxy S5

Hi, i really need help on this one. My phone keeps saying no service , but 4G works fine. If i turn on flight mode and disable it again , i got connection for about a minute before going back to no service. I tried a different Sim card, same issue. Both simcards work fine on my S3.
does anyone know a solution? Thx

Impossible to say since you provided no details as to which S5 model you have, which firmware, which carrier, et cetera.
Try to discern a pattern in when the issue happens. Possibly you could try updating your firmware. Or open a carrier support ticket.

[Q] network problem (very strange)

Hi guys, first of all i made searches and etc. and found nothing, this is very strange issue,
i have an s4 (I9500) and cell network is not working well. in E mode (i mean 2G) all internet voice and texts are working as should be.
in combined mode, if internet open then no network, or sometimes E with data but no 3G anyway. when internet disabled all is good.
in WCDMA mode, if internet is open, then nothing no internet, no voice no text. when internet disabled all is good again.
strange thing is i can use 3G very different way.
check 3G or combined mode first
make a call
after connected call open network data ( internet)
in a few seconds i have 3G internet. but if call ends no data again and after while no network either.
for troubleshooting in 3G mode before signal lost i see H or H+ sign on my phone but only up arrow shows no down arrow i think that mean 2 thing
1- i send a request to carrier but no returning
2- i cant send a request but phone try to send.
it was the same in 4.4.2 firmware, now i have 5.0.1
i try to patch modem with other firmwares modem files but i could find only 4.4.2 modem files. and tried all of them but no luck
so i want to use 3G mode, my phone has warranty but glass broken and in my country it is avoid warranty.
i have no box jtag or z3x box only have cwm mode and odin with usb. so is there any solution to my problem.
my phone info :
Android version: 5.0.1
Baseband version: I9500XXUHOD4
KERNEL VERSION: 3.4.5-4727708
Build number: LRX22C.I9500XXUHOD4

Check the SIM Card and change it for one new.

Factory reset your device then. This look like hardware problem anyway

I already tried that too, factory reset, clean to install New rom, and no luck...
Looks like to me software problem too but i cant fix it.. Thats why i choose title as strange i dunno what to do now..

I think im having the exact same problem, it has been like this for the past 3 months. Unable to find any solution. Tried pretty much everything. The problem started 3 weeks after I installed cyanogenmod. Flashed back to stock rom but it didnt fix it.
Let me try to explain it:
I ONLY got internet + a normal cell signal when im on GSM mode.
As soon as I switch to WCDMA - WCDMA/GSM or LTE/WCDMA/GSM I dont have any internet or a cell signal, leaving me with the only option which is GSM, but that gives me Edge internet which is really slow.
The things I tried so far:
- Different ROMS
- Stock ROM
- Updated my APNs manually and automaticly
- New sim card
- Opened my S4 to check for any damage or water damage, everything looks fine!
I tried my SIM card in my friends phone, I got perfect 4g then.
Im starting to believe its a hardware problem

When turn of data in 4g or 3g Mode can you see signal? Can you make a call?

International Tab A with S Pen

Found someone selling the international version of the Galaxy Tab A with the S Pen, model is SM-P585 for $160 and got him down to $130, haven't looked at it yet so don't know if it's in a different language or not, and obviously no warranty. But looks like it's the LTE model, won't be using it. Said it came from Korea, looking at the specs between the US version and Korean version looks the same except the Korean version has 32 gigs of ram vs 16. Only thing that worries me are updates down the road and compatibility with the app store. Will certain apps not load if it sees it as an international version?

hard to say
i did exactly what you are contemplating.
The unit i received boots and works fine via wifi. It does not work on wireless (cellular) networks, even though it has valid SIM card installed. Which is why i'm here, since i am going to try to flash firmware of a different region that has compatible bandplans to where i am. I've researched all that info on the web, and have chosen a "most likely" candidate.
The firmware it arrived with seems to be Singapore and Vietnam based. I'm going to try to flash Malaysian firmware and see what happens.
FWIW, the device will not upgrade via the built in upgrade option (in settings). It returns an error. Current android V 5.0, but i know htere is valid 6.0 firmware available. (which is what i'm going to flash).
I have verified using "System info for android " app, that it sees a network, but is simply not connecting. the curious thing about the situation is, that although the tablet will not connect to the cellular network, it does show the onscreen icon for network strength (which is very strong, 4 or 5 bars). So the device is recognizing a signal, but will not connect. I have used sim cards from several carriers, and "scanned" networks" which gives a list of expected locally available networks, but the device will not connect to any of them.
If anyone reading this has any ideas, i'm happy to hear them.

Good to know thanks. I don't plan on using it for the cellular part just WiFi, don't want to spend money on a data plan. I did find several sites that had marshmallow but you had to use odin I believe. Also found this thread incase it helps you.
https://forum.xda-developers.com/galaxy-tab-a/help/sm-p585-flashing-firmware-variant-t3498225

I had the Tab A 8.0 with S Pen (SM-P355) the international version capable of making phone calls. I don't think it was ever sold in the US. I had no problems loading any apps from the Play store, including banking apps and others that were regional or required authentication, like Uber.
The last version I received (before cracking my screen) was 6.0, pushed via OTA update.

Radio off / no network - LG-H990DS - do I have any options?

Hello,
Hoping someone may be able to help me
So this morning I lost the ability to make voice calls and use mobile data on my LG V20 (H990DS variant - totally stock). In the top right-hand corner where it shows the mobile network strength I have an empty box with an X in the top corner. Everything else on the phone is working hunky dory. Strange as the phone is stock and this didn't happen after an update, etc. Obviously it could be a hardware failure but I'd like to rule out it being a software problem as I really quite like the phone!
The phone knows a SIM card is installed as it knows the IMEI, APN settings etc. However it just won't connect to a network. I've checked the settings and the service state is set to "radio off" and the mobile network state is "disconnected" which makes sense given I can't get onto a mobile network.
Question is how do I turn the radio back on? I've tried what I think is the obvious stuff:
1) Removed the battery, left off for a couple of mins and rebooted (hoping it will then rescan and find the network) - no change
2) Factory reset - no change
Given I have the H990DS variant do I have an options? I say that as I thought this variant wasn't particular friendly in terms of flashing, ROMS, etc.
I'm a n00b but can follow instructions so if anyone has ANY advice I'd appreciate it!
Thanks muchly in advance.

see if the sim card is getting network in some other phone

Sounds like a hardware failure
Sent from my LG-H910 using XDA Labs

It could indeed be a hardware failure but I find it odd that it can read the SIM (knows the IMEI, APN settings, the number, etc) and I seem to recall when I first got the phone I had to jump through some hurdles to get the SIM to work.
Is there no way to toggle the radio on/off? I've tried *#*#4636 ... but it won't give me access to the phone information section to reset the radio here ...

did you find a fix?

Urgent : Unlocked at&t s7 No Signal at all; sim slot/antennae fine

Hi guys,
Been into android modification since 7 years but gave up since my last 2 phones. So i got this unlocked at&t galaxy s7 in uae and it worked like charm, the network and coverage. I then started usingthe phone in pakistan too and it worked well even here. So one day i connected to gear vr so that i can initiate the oculus data installation as first time setup but the gear vr kept on disconnecting automatically. I have used it before too but never had problem. Then i rebooted the phone and i find that i have no signals at all even though my sim contacts are being displayed and there is no “no sim” message on statusbar even. But dont have any signals at all. I then inserted my sim to iphone and it was working perfect. Then i inserted different carriers sims to s7 but yet they werent working even. I then cleared the cache, factory reset, cleaned the sim slot and the sim , but no success. I left ky ohone turned off for days andeven drained battery 100% many times to calibrate and perform hardware reset but no success. I then sent the phone back to uae for repairing from my friend as i thought that the antennae were the one’s responsible but before he even thought of disassembling the ohone, he inserted uae sim and it worked perfectly. Call and data were working perfectly. Any idea what is the problem? Kindly let me know pleaseeee. Is there any problem with frequency? Like gsm or cdma? But the phone worked before. I tried to enter the settings of manually selecting networks but there was error popup “No service and signal”. Signal strength 0asu -113dvm

Forgot to tell, my phone has never been rooted, i even tried to enable/disable “Enable hd LTE features” but no luck. Its on 7.0. Dont recieve OTA. Not blacklisted either. Pakistan doesnt have CDMA. I have even noticed it recieving weak signals compared to my iphone when the phone was working ok. And my radio is showing to be off and when i turn it on from the dial code menu. It doesnt keep turned on and it turns off automatically. I still have the imei amd baseband version. Dunno what the issue is.

Kindly reply guys
Please help

Manually enter your carriers information you'll have to ask them or look it up online sure its easy to find they might even help you in store
Its not good for you to buy these US phones outside of the US because changing CSC to INS/INU/PAK could prove to be difficult being it was never supported by snapdragon G930A model but only exynos G930F although it's not impossible
/system/csc/others.xml is where your answers are waiting for you unless you update to oreo then it'll be in /system/omc/cscfeature.xml and cscfeature_network.xml
You will need a root file manger to be able to see what I'm talking about then you will have to figure out what those "strings" mean
Unless you want to mod and figure out make your phone awesome just flash other US firmware that uses gsm network only i think ATT only uses gsm and you can root to debloat ect.
Here's a method for rooting
https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616/amp/
I'm sure there's people in your surrounding area that are into androids and rooting that understand and can help you figure things out if you know any one woth a G930F/G935F INS/INU/PAK thatd be awesome. If your imei number is truly gone from your phone its should still be on the back of the phone
I know this isn't the best help but you aren't the first post I've seen of Pakistanian with US S7 tryjng to figure it out.. idk if he ever did but if you learn you can help others as well
*note: when I say change csc I don't mean flashing firmware in odin, that is impossible. I mean porting it yourself with root like in the link below this one
*another note: I am not saying use the link below as anything other than an example because again that link was developed for Eynos phones and not your snapdragon so it probably wouldn't work but just so you have an idea of csc
