Hey guys, I'm using the Galaxy S3 and my current carrier is Rogers. I've always been on 4G in the area that I'm in, and with the countless roms I've installed I've never come across any problems. Today I was trying out some new roms, but when I flashed them, I noticed that it swapped from 4G to E(aka Edge). Even if I flash back to my nandroid backup or even a fresh install if the previous rom I was using, I'm still stuck on Edge. Now even though it says I'm connected to Edge, never mind reduced speed, my internet just doesn't even work at all. For some reason even if I'm connected to wi-fi, no matter what I do it says there's no connection. I've read about flashing modems, which I have tried and it seems I'm doing it wrong? I put it on to my sd, boot in to recovery and flash it, but whenever I do I just go in to an endless boot loop. I've spent the past six hours pulling out my hair and trying to get this fixed but no solution yet, so now I've put my hope in to you guys! Any help would be appreciated!
Thanks!
P.S. I'm sorry if I can't reply back right away, I'm currently doing night shifts at work and even though it's 9:45am here, it's technically my bed time, so I will get back to you as soon as I can!
Some extra information if it may help - The rom I was using that worked properly was Triune 2, I've played around with a few roms since, but the one that originally swapped my 4g to Edge was Mark of the Dragon 3.0.
I can think of two possibilities:
1) Some ROMs will reset your phone's internal network settings to only use specific types of networks (e.g. when I first got my phone, the CM10 build I flashed at the time disabled LTE). You can check this by dialing *#*#4636#*#*, going into "Phone information", and scrolling down to "Set preferred network type"; you'll want one of the LTE settings.
2) Reportedly, your phone's IMEI will sometimes be erased during a ROM update (check this in the Settings -> About phone -> Status menu, or in the same "Phone information" menu as above). Check here if that happened.
Hey, I gave number 1 a shot and everything was fine, so I took a look at option 2 and my IMEI isn't gone, but it's showing "0". I searched online and it seems like "0" means it's been deleted, so I'm about to give it a go and see if I can get it up and running. Anyways, thanks for the reply! I'll post and update on how everything works out.
*UPDATE* Alright, problem fixed! I'm back at 4G, everything is running smooth and fast! Took a little bit but everything is working fine, and now I know how to fix this problem if it should arise again, thanks again for the help, I appreciate it!
Hey, I'm back again. Well, I thought the problem was fixed, I was back on 4G all day until a little after I started work at around 10:30pm when my network swapped back to Edge and it's been there since(now 6:57am). My IMEI is still intact as well. I've tried flashing back to stock with odin and injecting the file to see what happens but no luck. Unfortunately I haven't reached the 10 post marker which means I can't ask for help on that part of the forum yet, so here I am in your hands once again, any help from you guys would be greatly appreciated!

Out of curiosity, have you checked the "set preferred network type" setting again?
I've also heard recently that there may be some problems with Rogers APNs in non-standard ROMs, so it might be worth checking your APN settings.
Or, it could be an LTE network outage, unlikely as that seems...
Yes I have and everything is fine. However, I was looking around at a few things some other people have done, not with the exact problem I have, but similar, I tried something out and it worked. Dial *#197328640#>UMTS>DEBUG SCREEN>PHONE CONTROL>NETWORK CONTROL>BAND SELECTION>LTE BAND PREFERENCE>LTE ALL, let it sit there for about 30 seconds and then reset the phone. Do it again, go in to BAND SELECTION and then choose AUTOMATIC, wait 30 seconds and reboot your phone again. I'm back to 4g and actually, it seems faster than when I originally had 4G, but I think I'm just used to how slow Edge is now . Although the other fix got me back to 4G as well, but then it swapped back to Edge so I'll wait for at least 24 hours before I can confirm it completely fixed. Once again thanks for the response! Most helpful forums I've been on!
It hasn't been 24 hours but I thought I'd report back while I'm on my break. I'm still at 4G so things seems to be going well, hopefully it won't go back as it seems like it will stay at 4G. So, unless I'm having troubles again, rather than waiting the 24 hours and posting an update, think of it as a good thing that I don't report anything(or at least I will, since it's my phone ) Thanks again for the help, I appreciate it!

I just switched to Fido (uses the same towers as Rogers) and this advice is what got my LTE working.

Thanks do much for this, I had the exact same problem after flashing MiuiAndroid and Wicked Sensations. Don't know which one effed it up but it was definitely one of those two. Also, I Don't think it is a placebo effect on the speed increase, cause mine is blazing fast after implementing this fix. You should maybe re-title the thread so others in this situation can find this fix, good find and thanks again!
Just want to confirm that this particular code can only be entered from a stock dialer? I I tried entering it from cm10's dialer and it doesn't do anything.

2 things that i can think of...
1)Make sure you have the LTE option selected in your Mobile Networks.
2)Take a look at your APN settings for you carrier. Flashing roms sometimes erases these settings.
That's where i would look first...
Cheers

Please let me know if you fix this. I'm having the same problem, and playing with LTE band selection doesn't work. When I force the band selection, the phone won't even go into service. The same thing happens with WCDMA.
Apparently, the nvbackup stores more than the IMEI. Even when you replace the IMEI, nobody seems to get data back. Unless, of course, you had a backup. Which, unfortunately, I was not smart enough to do....
Hey guys, I have the exact same issue as this:
-I flashed CM10.2 from a CM10.1 nightly which wiped my IMEI. I injected the IMEI using NV-items reader/writer.
-Reloaded stock ICS rom, IMEI returned but couldn't get up from EDGE
-Tried using the peoplesarmy's removed IMEI restore tool, didn't do anything
The phone still works, only its on EDGE all the time.
Literally the only solution for me was using my warranty and getting a new phone.
REPEAT: BACKUP YOUR **** OR YOU GOTTA GET A NEW PHONE!

Randomly on Saturday my phone decided it didn't want to have any service so I reflashed the rom which didn't help, I then went to build 29(this is open kang) still no luck so i went back to build 28 and m4 still nothing, I am now on liquid smooth and I still cannot get service. They are both GSM roms and I baseband is not showing unknown. Anyone help?
Luke
Do you have powersave options in the rom? If so, try turning that off, it did work for me (on AOKP 29).
All you need to do is download your radio and flash it! You can find your radio in the development section of the galaxy nexus forum

ndualls and
Neither of the above worked any other suggestion? This just happened out of the blue originally not from flashing
Since it happened out of the blue, did you check with your provider if they have issues? (maybe too obvious, but just checking).
You can try and remove the battery for around 5 mins, and then restart, this way you'll get a clean boot (if Im correct).

You did try going back completely to stock yes?

Are there any APN settings visible under accespoints? If so, check with your providers settings to see if they are set correct.

I have tried going back to stock but the toolkit does it and then it just goes back on the old rom
You might want to check with your network to make sure your phone hasn`t been blocked/barred
The same thing happened to my Galaxy S2 which i i bought from Ebay about a year ago. I tried everything to fix it but later found out my phone was blocked when I took it to a Samsung service center.
I would never buy a phone off Ebay again. people sell you the phone and then report it lost/stolen so they can get a replacement.
Also check you IMEI hasn't been changed
Still no luck with this, have even gone back to stock and it hasn't changed

'm gonna try and make a long story short. Yesterday I purchased A S3 from ATT..Everything was working fine right out of the box no problems, lte and everything..Well earlier today I rooted my phone and everything seemed to be fine, I even flashed a rom and that seemed to be running fine also, but I noticed when I flashed the rom on the tool bar where it shows what data your running other than Wifi, it said H, don't know what that would be but I know it wasen't lte....So I thought maybe something was wrong with my phone, so I took it to the att store and showed them I wasen't getting 4glte..So they looked on the compyter and everything looked right, then they took it to the back where the service center was and flashed it back to factory....AND WHAT DO YOU KNOW??? It worked...I got 4glte right away..It said it right on the toolbar..I was so happy its working again like it should be...So I get home and root the phone again..everything went fine with the root, well it seemed like it BUT WHAT DO YOU KNOW...YOU GUESSED IT..NO 4gLTE...WHAT is going on here...and this was just off a fresh root no roms or anything...So I'm stuck I don't know what to do or if anyone else has expierienced this or knows a fix...I really want to keep my phone rooted so I can run roms and programs like Titanium Backup
So if anyone knows and can help I'd really appriciate it...thanks for your help and time...
I'm keeping my fingers crossed
As you can see from the picture you can see 4g on the status bar, but check out the speeds...and I'm in a great spot for lte..so something is wrong
Its kind of normal that lte dont work on some roms, you could just stay stock and it will all work, Im not sure why root would kill your lte, how are you rooting?

1st wrong thread, this has nothing to do with development, 2nd if ur getting 4g lte issues then speak to the company u got it from, because not alot of places can support lte atm its like a transition thats happenning 3rd what i can suggest you do is grab a tool like odin, and odin back to stock rom and then use snapdragon tool by mskip its the 2nd or 3rd from this forum up, and go from there and that should help u further on in getting back to normal , and if you're flashing jelly bean roms or what not, you have lte still but it'll show as 4g or what not, which rom have you flashed btw.

You need to check your APN settings and make sure you're using the proper LTE APNs for your carrier and make sure that LTE is available in your area 100%.
Also you need to enable LTE on the mobile connections screen within whatever ROM you flash.

but he's saying he's flashing a rom and losing LTE, but apn most the times stick, thats why i was wondering which rom was it, because then we can let them know to make sure their apn sticks make its easier for anyone else that flashes.
I know first hand wali and his partner in crime have stellar ROMs flash one of those guarantee you won't be disappointed

It could also be that he has lte but the icons says 4G for lte I think it's the case for some roms. Because the phone companies made us believe that hsdpa+ was 4G when in fact it's more like 3.7G more or less. What I'm trying to say is did you do a speed test to make sure?
4G might just be lte after all.

lets blame the companies for skrewing everything up with toggles.
run a speed test and look at more info and see what it shows, also check your apn settings via settings/more settings and mobile network then access point names and then take a screenshot if possible by holding power + home button and post it up, because if u should have LTE service ur apns must be LTE otherwise you will be defaulted to regular apn which might throttle you like whoa well i know our ics doesn't do that but not that i hate anyone's ics, Nun, Ariel and Kyan all have done a good job in their ics's.
I don't know if this helps but go to settings and then about, then status and check network, most likely says UMTS or well it does for me on ALL 4.1.1 rom's. But, go to mobile networks and try to connect to another provider than yours, then when it says it cannot connect, re-connect to your own and I bet you will get HS+. Only problem is, if you toggle on wifi or reboot, you will have to do this all over again to retain the higher network connection.
I have not been able to come up with a solution yet and do not know if it is a 747m problem only or if it effects 747 as well.

First of all this is my first time posting here on xda but have read a lot of things on this website, and i apologize if i have placed this in the wrong area.
I have seen other threads about this issue but none seem to be quite like mine.
So i had cyanogenmod on my galaxy s 3 att/rogers, I had it on my phone for a long time pretty much the entire year i have had the phone, when randomly last night my service just stopped. I cant make phone calls, text, or use data. But my wifi still works. so basically my phone turned into a tablet.
Things I have tried to fix this:
1: restored using nanndroid backup (no effect)
2: flash a different rom "PAC Rom" with its kernel (no effect)
3: Restored phone to complete factory defaults using odin (no effect)
4: Tried different SIM card in my phone to see if it would work (no effect)
5: Tried my SIM in different phones (worked)
6: Restored phone to factory default using samsung kies (no effect)
So can you see my delema? No matter what i try the service just will not activate and only says "rogers emergency calls only". this phone is only around a year old.. This isn't a common thing to happen is it?
Anyways I would be very, very happy if anyone could help me fix this problem. I apologize if i get back to you slow as i have to go to work in a couple minutes, my boss is probably going to be pissed I have no phone. :crying:
Nothing? Nothing at all?
I had similar issue I just solved. I had only lost data however. I would suggest maybe checking your apn settings. It maybe flash a modem. I was able to make calls/texts no problem but no data at all. I Google the apn settings and now everything works great

Apn settings were all right. Not sure what has happened.. rogers told me the phone was toast but I have a hard time beleiving that from someone who looks at my phone for 30 seconds and says that. Either way I'm picking my note 3 up friday. Not through rogers, since they were a royal pain in my wallet. Bell ftw
Not really sure if I should mark this as solved due to the fact its not?
It's been said a few times that SELinux settings have an effect on mobile connection on some phones, not all, but some. Mine being one of them, that theory has also been criticized, ironically by those who's phones do not suffer from the issue. Anyways, if your trying a 4.4 ROM and have no APNs, no baseband, IMEI etc grab SELinux mode changer from the market, set to Permissive and be on your way. Why or what causes it is beyond me but changing to Permissive solves it. It takes a few seconds after boot for supersu permissions, a few seconds then for your APNs to be populated and baseband, after that you will get mobile connection working.
Hope this helps someone else fighting the same issues. Here's a video showing before and after, a little wait at the APN screen the second time for them to be populated. Also, sorry for the quality, just easier to record the screen directly compared to holding a camera.

Glad it was of help, just passing on what I have read and tried to make it easier to find so made a thread for it, some of us have the issue but appears the majority do not.
I had the issue initially when installed with twrp, did it once again with cwm, worked like a charm. Good info to keep in mind though.
anybody got the apk handy they can upload? flashed the latest cm nightly not knowing it was 4.4.1, and the store won't connect via wifi for whatever reason.. i'd rather not have to do a clean install to get my phone working again.
Thanks.
Nevermind, I managed to pull it from the woman's unrooted moto x. It's here if anyone else needs it..

just out of curiosity. vAre you guys having any issues with the AOSP roms slowing down the data speeds? I know people have said for a long time since GB I think that the tw roms are much faster than AOSP I never saw that on HSPA+ but I am on simple moble and they just turnrd on their LTE and my phone gets an average of 28 down and 14 up. on tw roms but on AOKP or other AOSP roms it gets 8 up and 3 down. Like the lte is not working. Anyone else have these problems?
I love you.

Hey everyone and thanks for taking the time to read this,
So the story goes as so: After doing some research couple months ago about the capability of the Verizon Galaxy S3 to work on T-mobile, i purchased it, and got it to successfully work on T-mobile(texts, calls, wi-fi). The problem is, i just recently upgraded to include a data plan, and i cannot access the internet, despite taking my phone to my cell phone dealer and contacting T-mobile.T-mobile even sent me a guide to do a mastery reset to factory in hopes to solve this problem, only to tell me afterwards that the phone version SCH-I535 is a "verizon locked-software" and i won't be able to set up an APN to work on the T-mobile network. This was all due to the fact that i was not able to set up a APN for T-mobile, and every time i tried to access it through setting, it brought me to a blank black page with the only option of "Reset to Default". After reading other forums and talking with some people, many have suggested i take this issue to XDA to find a solution.
So, here i am.....Does anyone know if it is possible for me to break/root/ or whatever it is called so i can successfully access the t-mobile network on my phone? Preferably an easier guide since i am sort of a newbie at this sort of stuff.
Thanks again for reading.
Before your Contract change, you were able to receive and make calls successfully with T-Mo Sim right ? Even now you can make calls too correct ? The reason I am asking this is to be able to check if you are really unlocked off of VZW. If you are not unlocked, then that would be the first step.
You are right, the APNs do drive Data Connection. If the stock firmware does not allow you to change APNs then you will have to root. Please post a screen of your Settings > About phone that shows your Rom Version, Baseband and Kernel.

Hey Perseus, thanks a lot for taking the time to reply. I bought the phone in the summer off someone who had verizon. I have always had T-mobile, and considering this phone is GSM, i decided to buy it because it would probably work for T-mobile. I had the phone unlocked, and i am currently using it to make calls, texts, and even use wi-fi with no problem. The only problem at this time is that i recently added a data plan which i cannot currently use. Here is a screen shot of what you have requested.
Thanks again
First try
Settings > More > Mobile Networks > Preferred Network Type.See what it is set to. Change it to LTE/GSM/WCDMA if needed. See the other option System Select as well.
Also separately try the following.
Hit ##DATA# in the Dialer. In the subsequent Menu choose EDIT > OTHERS > LTE APN
If all fails, please Root the phone and then try. The way you go about is
1. Flash a Custom Recovery via Odin. Make sure the version of Custom recovery is for your model D2VZW not D2TMO.
2. Flash a SuperSU zip file via Recovery and then hit fix permissions in the recovery.
Try the APN Settings after that. IF you can actually access them, then set them according to this link.
If all the above fails, I'd suggest a custom Rom for d2VZW.
You will never get 4g trust me I had one... you will just get the E

Ok, so i tried to changed it to LTE and i got no service at all, so i switched it back to Global. I also tried the dialer thing several times, and got the " connection problem or invalid MMI code"
So i guess i am going to have to root the phone? Does anyone know a good video tutorial or written tutorial on how to safely do this? Also, what exactly is rooting?

You have to enable the mmi codes to use them. Anyway as stated above your reply you will never get 3g or 4g just edge (seen it personally) which is pretty darn slow.. Not worth it if you ask me and be paying for data.. If you still want to root it and keep trying to add sons check the Verizon forums.. They could probably help you a lot more than on this side of the forums

Guys, he is not getting ANY data signal at all. His problem isn't getting the specific icon but being not able to change APNs.
@HackThisThing, you are better off following up on Verizon Device forum. That forum does have a video tutorial for Rooting. Here's forum link.
I don't think you will be able to change APNs without rooting. I checked with a buddy of mine who has the same device as you.
Here's a good answer to What is Rooting ?
Even if you CAN fix it, why bother if you can only get 2G? I'd sell it or trade it for a phone that's more compatible with T-Mobile 's network instead of paying for data and only getting dial-up speeds. I get that solving problems is fun, but OP do you want to live with only 2G?

I don't agree with that assessment. Just like the T999L phone, this device will work on LTE Bands just fine. OP just needs to wait for LTE to be rolled out in their area. There's a coverage map and roll out schedule on T-Mo website and the T-Mo News blog.
It's worth a look, but could still leave them with patchy coverage. If it's going to be a while, why wait when it's not hard to just trade the phone? I guess I don't see a reason why hold out on getting a Verizon phone to work when you could just get one that works now with little to no monetary loss. It's just a Verizon S3, not really something worth "waiting" for when they could get the same thing but more functional on their network of choice.
They made an honest mistake and waiting might give them "good enough" service - but other than that they're stuck with dial up speed only and risk bricking a phone they could just trade or sell now.
Maybe I'm just impatient and risk averse.

OP has already purchased this VZW version.
Same Problem...
I have the same problem....
How to get any type of data...?
