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.

I have double and triple checked the APN settings. No luck. I feel like a complete retard, but why cant this phone connect to the network?
It doesn't even appear to try. Any suggestions?
I haven't a clue why, but I've been told multiple times that the infuse won't be able to connect to Tmobile data services in any manner.
I'm in the same boat, when did you notice this? I ask because mine just started doing this yesterday. Here's a brief synopsis of what I've done:
- I was running stock GB 2.3.6, from the Heimdall One-Click...had no issues for weeks (only had it a few weeks); once I realized that I can't get anything higher than EDGE speeds due to the hardware requirements, I went ahead and purchased the GN. So, my neighbor told me that she went to T-Mo (same phone) and the gentlemen 'input some codes' etc etc and she now had 3G (can't verify, I didn't grab her phone). I had an idea that he went into the phone testing mode (by doing the *#*#INFO#*#*) and maybe changed some of the network settings in there. So I figured I would give it a shot before I put it up for sale since my GN was coming today. So I went in and tried a few things, all to no avail....and then realized that I had NO data at all.
So at this point I did a factory reset (no luck), flashed the firmware/modem/etc from the Heimdall one-click, reset the APN settings (multiple times)....everything that I know to do with it....and STILL no data. But I can place calls, get texts, etc with no issue.
What's strange is after I flashed the stock GB rom, I went back into the testing mode (I guess that's what you call it???) and was checking a few things:
- if I run the ping test, it comes back null (no surprise) BUT it also lists 'GSM Service: In Service' and 'Network Type: EDGE'...it does show GPRS as disconnected.
I tried my SIM in an unlocked iPhone and it didn't have data connection. But I also put my roommates T-Mo SIM in the Infuse and it didn't have data either. I haven't had a chance to see if my SIM works (data wise) in the GN, because I haven't gotten it yet.
Any ideas on what to do?
**EDIT**
For some reason the data began to work about an hour after I posted this. Maybe the phone knew I was asking the experts and it had no where to hide?? Either way The_Joe I would try to maybe do a factory reset and if that doesn't work, to try to re-install the ROM/OS again.
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?!?!?
Ok here is the problem... I rooted the phone, played with some settings, explored the android platform in general. Somehow, my data has stopped working. I can make calls and send texts no problem, when I try to access internet or google play store, it fells me that I have no data connection available or something of the sort. I have tried flashing different roms, played around with switching between Global and Lte/cdma radio bands. When I switch bands, I get either 4g or 3g, but within half hour it stops working again. After a restart, same thing happens, it worka and then atops. I figure there is something messed up with the modem. Please advise.
Also, anyone else experiencing sudden restarts with CleanRom 5.0? My phone reboots every once in a while for no apparent reason.

Have you tried flashing a different modem?
Worst come to worse, ODIN back to 100% stock and start over.

No clue how to flash a modem
http://rootzwiki.com/topic/34053-of...zon-sgs3-sch-i535-odin-or-recovery-flashable/
Pick the latest from the right column and flash in recovery as you would a ROM.

Looked into it a bit more.... my 4g or 3g works after a restart as long as there is a demand for it, ex. While surfing or streaming radio, as soon as there is no demand, the phone shuts it off and I can't turn it back on. It tells me no signal found for mobile networks. While voice and mssg still work. I refreshed the modem and that didn't help. Short of going back to stock, any other suggestions?
As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
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.
