I bought an AT&T S3 and factory unlocked it, it worked perfectly on T-Mobile's 3G/4G network. But then I decided to flash a custom kernel, stupid me. After rebooting, found out i was stuck on edge and IMEI number was "lost".
I flash the stock rom back on and that didn't work so I used peoplearmy's guide to inject the IMEI number back into the phone. I even tried his other method to get 3G data back, but no go.
So i have the IMEI number back on and everything but I'm still stuck on "EGDE: 2".
I've tried the WCDMA Preferred method but that didn't work. So does anybody know how to get 3G/4G back on?
Any help will be appreciated Thanks.
EDIT: Alright solved this problem. If your having the sane problem just use peoplearmy's imei tool to inject it back in. After that back it up again by putting it in diagnostic mode and using qpst. Then (here's how you get 3G/4G data back on your AT&T S3 with T-Mobile network) use peoplearmy's qnc generator tool to generate a T-Mobile back up and restore that back to your phone and BOOM! Your done! You can find peoplearmy's thread on xda. Or Google "fix/tool qnc" and it should be the first result

Thanks for the reply
I actually tried this already and was able to get my imei back on my phone. But im stuck on "EDGE:2" while before i was able to get t-mobiles 3g/h+, thats what im trying to do.
so i installed TWRP on mu unlocked and S-OFF phone, and rooted the phone. then from the recovery, i made a nandroid backup, wiped the phone, and installed this ROM. even though all traces of Verizon software is now wiped off the phone (i hope!), it still only connects when the Verizon SIM card is in (and it shows the Roaming sign; fyi, i am in Canada now). it won't give me a voice nor a data connection with my Telus SIM card nor with my Rogers SIM card. so, i went into recovery, wiped cache, and afterwards, the phone was stuck in the boot...i had to go to recovery again, wipe everything, and restore my nandroid backup. the phone is now back to stock Verizon software, and it still only connects when the Verizon SIM card is in. it should at least give me voice connection with the Telus or Rogers SIM card, but it won't. something must have happened to the radio when i flashed the ROM, and i can't figure it out.
do you guys have any troubleshooting ideas? can anybody guide me towards a fix/troubleshooting method? i'd appreciate any help...

This ROM is still very early and has some bugs. Making it work for people not using it on Verizon isn't a concern of Santods at the moment. Switch to something that does work for you until he gets the rom further along.

thank you all for your help. it's not just APN though; with that ROM, i cannot even have a voice connection, let alone data. and even though i restored my stock backup (and now running the original ROM that came with the phone), the voice still doesn't work; it only functions with a Verizon SIM card.

Well.. when you were on cm you couldn't get any service? Is your carrier lte/cdma or gsm based? Are you showing global mode when on cm? It also can be a case where some qpst work needs done to enable the extra radio bands needed to pickup your carrier.

i'm guessing by CM you mean CyanogenMod, right? if so, i was never on CM. i was using the stock ROM (4.4.3, Sense 6.0, Verizon bloatware), and then i flashed the Lollipop ROM by santod. the phone initially could connect to Rogers and i had voice and very slow (i.e., EDGE) data speeds, but after flashing the ROM, my phone lost the ability to provide any sort of voice connection except when i'm using my old Verizon SIM card (that shows the Roaming icon, because i'm in Canada now).
i could try CM, if you think it has less possible bugs. do you suggest i do a factory reset while on stock ROM and then flash CM?

Yes. Factory reset on stock recovery. Then flash twrp and sideload the latest cm build. I would probably stay with cm11 for now too.

Well you can do a factory reset on stock Rom and let it boot up and then copy cm over to phone storage for flashing.....or...adb sideload.
When you boot into twrp under the advanced options there's an adb sideload feature. Once the phone is in this mode you can use you pc to send a Rom over using the command "adb sideload nameofROM.zip". Your pc will send the Rom over and the phone will flash it once it's copied over.
Backup the internal sd card of your phone before you factory reset. I've forgotten so many times it isn't funny.

ok, i did all that with MDMower TWRM 2.7.1.2 this time. CM11 is up and running now, but i still have the same issue. my Telus and Rogers SIM cards lead to a "No Service" icon, whereas my old Verizon SIM gives the Roaming indicator. funny thing is that with all three SIM cards, the correct set of APNs is loaded by default when i boot the phone, but selecting those APNs don't change anything. i also tried Global, GSM only, WDCMA preferred, and some combinations of those modes to no avail (the only SIM that leads to service is Verizon's). it seems like the phone is hard-coded for that particular SIM card, no matter what.
any other ideas? could the radio have become corrupted somehow during unlocking/S-OFF'ing/flashing? if so, what is a workaround for this?

I would bet they are using a frequency that's not currently unlocked on your radio. There is a lengthy how to posted on Google about how to enable Qualcomm radio bands.

aha, great! i know that Verizon HTC One M7 uses
CDMA 800/1900 MHz
GSM/GPRS/EDGE 850/900/1800/1900MHz
UMTS/HSPA 1900/2100MHz
LTE 700MHz (Band 13)
according to this Wikipedia page, Telus has a HSPA+ network on 850/1900 MHz (so at least the 1900 Mhz band should give me something, shouldn't it?), it has CDMA service that's supposed to shut down completely in 2015 (it is out of service in some places in Canada, but i'm not sure about my area), but has no GSM service at all.
thanks for the tip about enabling radio bands; i'll search for it...
[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.
i having same issue in M919
Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution
Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.
I'll try to be brief. lol .Before finding this site I brought my unlocked S4 mini to wind to see if it will work. The guy found the 1700 freq in the phone service menu and changed something and said it won't keep on 1700 then he said something about the nv write. After a while he handed it back and said it wouldn't work. I put my bell sim in afterward it said no sim. it won't find any bell sim now. I tried a friends telus sim and it finds the sim fine and shows voicemail notifications but when I tried to call it says not connected to network. I can see the networks but when trying to connect, the signal drops and phone says "network not available try later". After it tries to connect the signal returns to normal.
So I found this site
I successfully rooted the phone with S4Mini_RootKit_v2.zip. It worked fine but had the same network problem. I fully rooted with cm11, then 12. Same problem.
I loaded a pit file gotten gaciously from sammobile. Same problem
I've returned all firmware to factory and undone root but still same issue.
The imei and serial number match the sticker on the back so they are not invalid.
The wifi and bluetooth and general operations are normal.
I'm guessing that the nv was rewritten and to recovery as well? But I really don't know as I am very new at this but have been doing a lot of reading.
1. Is there a way to restore the nv without a backup from my phone?
2. Is there a way to restore the service programming back to factory default? (I've seen this question asked before but only found the answer it is proprietory, whatever that means)
I have qpst and efs professional and a qcn file I was able to download from the internet
3. This qcn file is from unreliable source. Could I damage my phone more than it already is, and can i edit my imei and sn into it?
Thanks very much.

I painstakingly manually edited using qpst and restored all changed setting to a previous copied save.
Ok So I have a T-Mobile Samsung Galaxy s3 (SGH-T999L) (LTE Version). I previously rooted it and installed custom ROM using Cyanogenmod, then changed to TWRP later. Then, i wanted to revert to stock and unrooted my phone. I was told to install latest firmware and did so (Android 4.3 T999LUVUBOH1). Since then, i went from T-Mobile to MetroPCS. The phone is unlocked. When trying to use metropcs sim card on s3, it works for about 5 minutes (able to call & text), then all of a sudden i get NO SIGNAL and cannot do ANYTHING! I used my husband's metropcs sim card and same thing happened. Then, I tried my mom's AT&T sim card and it did seem to work fine for awhile. I tried accessing mobile networks to change APN while I had my mom's sim in there and was able to but when i insert my sim card it says: "Insert Sim to access network services" and there IS a sim in there. Our sims work fine on other phones. I don't understand what's going on. I've tried to flash a modem and even rooting it again, but Odin keeps failing or not responding. I cannot flash ANYTHING!!! Please help!
Flash back to a stock ROM and make sure everything works. Once this is done, call MetroPCS to see if they need to register the phone's imei on their system.
Thanks. It had official stock Rom already on it. I can try again if Odin decides to work for me. I have USB debugging on. I'll let you know what happens. I will also call Metro PCS. thanks again.
