I recently acquired a Permanently Unlocked US T-Mobile Galaxy s7 SM-G930T. Since I have Verizon, I flashed it to the latest Verizon Firmware SM-G930V from sammobile using the latest Odin. Everything went perfect.
The only problem is that the wifi will not stay connected.
It will connect for a few minutes at a time, and then, despite it saying it is still connected to wifi, videos will suddenly not load, apps will not open. I run a speed test and then it will show the little exclamation mark on my wifi signal, only then showing that wifi is not connect or having problems. It's very tedious as I go based off the wifi signal to and since it says it's connected i am missing important notifications despite my mobile data being connected. I have unlimited data with my carrier so i could simply stay connected to mobile data at all times, but i would like to have my wifi working again. Does anybody know what may be causing this problem.
I tried flashing it back to T-Mobile. and once again everything works perfect. except for the wifi. So i believe it may have to do with the firmware, or maybe i need another file or files that i still need to install? I have been researching it for a week and i just can not figure out a solution.
I tried resetting my router, nothing.
Different older firmwares for Verizon from Sammobile, nothing.
Resetting Cache in recovery mode, nothing.
Unchecking Smart switch (function for it to switch between mobile and wifi automatically), nothing.
Unchecked Wifi and bluetooth scanning, nothing.
Can somebody please help?
Just asking, what were the bootloader versions of the T-Mobile and Verizon ROM's you went back and forth with? *Bootloader version can be found in baseband number i.e SM-930TUVS4CRL1, The 4 is the BL.

Bought a brand new unlocked Moto Defy and I'm having some WiFi and data connection issues...
To start things off, I cannot get any kind of data on this phone. I'm able to make/receive calls and texts with no problem but when it comes to accessing data, it's a total fail. I've added APN's for ATT (ATT MMS, ATT PHONE, AT&T PTA), switched the 2G/3G/auto under Mobile Network Settings, and I just can't seem to get data working. I get data just fine on my At&t Samsung Focus with WP7.
Secondly, I cannot connect to my WiFi router. I've reset the router numerous times, disabled WPA security, tried different security methods, and it just doesn't want to connect. The network occasionally shows up with great signal strength but soon after disappears. I went to the same room as the router and it shows up. When I tap on it to connect, it shows "connecting" and then "disconnected". I also get a WiFi symbol in the upper left hand corner with a question mark over it.
And to top things off, I can't seem to format my WP7 memory card so I can't even install any apk's or ROMs. For some reason, the 2GB card that supposed to come with this phone wasn't even in the box!
Any ideas? Starting to get frustrated, this is my first android phone (3rd android device, first 2 were tablets) so I'm eager to mess with this thing.
Uploading a short video showing the WiFi problem.
Thank you so much!
Also, running 2.2.2
Anyone?

So I've installed Cyanogenmod 7 and was able to get to the band settings but when I select USA Band, it says "Set [USA Band] Unsuccessful.
I found a working bp_nvm_default folder for ATT, replaced original with that, set permissions, and nothing has changed.
I am at a loss of what to do now. And after installing CM7, I have no signal what so ever.
Please!!!! Any ideas?!?!?
Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

I did try that. Nothing seems to be working.
Two days ago the Wifi on my wife's N5 stopped working. When Wifi is switched on, it never detects any available WiFi networks. I also have a N5 and mine detects several including our home network. I have flashed the latest factory image, but her phone still is not detecting any networks.
Seems like it is likely a hardware issue, any ideas?
If a stock image and and factory reset don't help, try checking for loose connections.
If nothing works, I think it is hardware- related.
This handset was absolutely fine until it updated to Nougat then it wouldnt sign onto the network. It see's the network fine, just wont ever register on it. Sometimes shows a signal bar but emergency calls only, other times a circle with a 45 degree line through it. I have tried multiple roms and all the same, I should add that Secure Boot is enabled and since it updated to 7.0 I cannot downgrade back again. I have checked the phone hasn't been blacklisted, all comes back clean.
Can anyone help? It works fine apart from this unable to connect to network, try later problem.
Thanks in advance

Hi,
I have a g930p running g930u Nougat firmware. I did an OTA update to Oreo and was not able to connect to my network after.
I'm in Canada and on Public Mobile which is owned by Telus.
I can see Telus, Bell, Rogers, and Freedom when I do a manual network search, but cannot connect to any of them.
I did some research, and I'm wondering if there are some issues with MVNO's.
My IMEI is present, so I don't think there is an issue there.
I was able to use Odin to downgrade back to Nougat. Everything works fine on Nougat.
I tried manually flashing the latest g930u oreo firmware after, and no luck. A factory reset did not help either.
Any ideas?
Thanks!
Same Issue here
Hello,
I seem to have a very similar issue.
Ever since the most recent update (to Oreo 8.0.0) my Samsung Galaxy S7 will not connect to mobile networks. The network symbol shows full four bars most of the time (sometimes the crossed out circle), however never indicators for mobile internet. I don't receive texts or whatsapp messages, neither can I send them, the browser says I'm offline. I can't be called and when trying to make calls, after a split second I get a prompt "Not registered on network" and the call ends.
Internet usage works just fine when using Wifi.
Also, the issue only occurs on default network settings: When I go to settings->connections->mobile networks->network mode and select "2G only", the phone functions as I would expect it to do. All other modes don't work.
Things I've tried without any form of success:
Flight mode on/off
Several reboots
Wiping the cache
Manually searching for network operators (keeps on scanning forever)
Resetting network settings
Resetting my phone to factory settings
Unfortunately I can't cross check my SIM-card with other phones or other SIM cards on my device. Since I've been using both for almost 2 years now, however, I don't think those are the issue.
Device: Samsung Galaxy S7 32GB
Android Version: 8.0.0
Product Code: SM-G930FZKADBT
Baseband version: G930FXXU2ERGC
Build number: R16NW.G930FXXU2ERGE
Network Provider: Mobilcom debitel (Via D2 network, Germany)
I really hope somebody has an idea for a solution, this unnecessary issue renders the phone mostly unusable :/
Hi
A UK user here, I have been experiencing some of the same issues that you have both mentioned. For me however periodically my phone will stop recieving network signal from my phone operator '3' and have completely no signal. This has been happening for a few months now and has happened since the last major update. In attempting to solve the issue, I often reset my phone multiple times to no avail and I simply have to wait until the phone starts to recieve signal again! Very frustrating!
I am not using any type of custom OS currently (or ever previously) and that was my main motivation to join this site, to jailbreak my phone and see if I can overcome these issues through custom fireware or alternatively installing older firmware where this problem did not exist.
The problem is widespread, a simple google of the issue or a visit to the Samsumg forum and you'll find plenty of users reporting the same problem, however Samsung seems to be doing nothing about it. Honestly, I am disgusted! I paid a lot of this phone on its release two years ago and I have simply been forgetten about and no one seems to care at Samsung to provide a solution or any information at all.
Best,
