Hi everyone,
I have following problem. I bought used phone with cm10.2.1 installed. After one day i realized problem with hsdpa connection. I put my sim card into another phone and it was ok.Then I started reading about issue and realize it could be problem with IMEI.
I check my IMEI and it seems to be ok. I went back to stock rom using Odin but problem is still there. I think I can connect to BTS, but in my phone mobile network type is Unknown:0.
I don't live in US so i don't have Us sim card, but my friends also in my country with AT&T phone could get access to hsdpa. In my country hsdpa is on UMTS 2100
Is there any way that I can check if my efs is ok? Could it be problem with hardware or rather software?
I found solution posted by umar4u, he attached file to NV writer to repair 3g and 4g issue. Is it save? Can I brick my phone or "only" mess in my efs?
Problem was solved writing NV items. I don't know if I can delete post, so please delete my post

Hey whats up xda. As some of you know the Electrify M as the sister phone to the Razr M. Ive used this phone for the past couple of months on PagePlus and just figured I'd start messing around with it to possibly be able to use it on tmobile/att. In the last 2 days Ive made some progress using a tmobile sim card. It picked up signal but wasn't successful with calls, text or data. I didnt have enough time to fully test it since its my brothers sim but at the moment have a simple mobile sim for testing which for a briefly picked up signal when attempting to register on the network and display (network with limited service found) and not finish afterwards saying something similar to (service not available please try again later). Well now when I try to search for the network on simple mobile card attempts are unsuccessful and displaying (network unavailable). It only displays the phone number and voicemail icon at the moment. I'm currently trying to detect network on simple mobile again and go from there. T-mobile sim belongs to my brother so I'll prob go pickup a prepaid sim soon to test. It still displays signal on lte13/lte14 when tmobile sim inserted but still no signal the active simple mobile micro-sim which I read people have had trouble registering on the network sometimes. If I get anywhere Ill post it in development until then I have to get my post count up to do so.
What did you do to get it to pick up a signal at all?
I've done the 8322 NV edit and tried both GSM/WCDMA and Global modes by going into *#*#4636#*#*. Phone is stuck on "Searching for Service". Even tried a few build.prop edits and using build.prop from my RAZR M. No luck there either. I've tried flashing XT907 modem, also erased modemst1 and modemst2. I also tried with and without flashing XT907's fsg. I don't know what fsg is, but the FXZ always flashes modem, fsg, then erases modemst1 and modemst2. No luck there either. Can't even turn on the radio with the modem FW from XT907.
The fact you managed to get it to show a signal bar at all is further than I got.

fastboot flash modem NON-HLOS.bin
I also did:
fastboot erase modemst1
fastboot erase modemst2
Because that's what the fxz does.
Didn't work for me though. No signal, can't do *#*#4636#*#*, can't get into Status in About Phone, can't get into Mobile networks in Wireless & networks, Baseband version says UNKNOWN. Maybe I got a bad download? It did seem unusually fast. My MD5 sum is C3F9B3BAD2D5454C4E6D6F7803136567.
UPDATE: Downloaded official Aussie FXZ and flashed modem_signed. Same thing. Either there's more to it, or guy that suggested it is trolling.
I found it in an old tmobile hack thread I think.
hello everyone, my friend got this phone and he was using all the time the 2G network. i am from greece, when i got the phone i saw that there was no 3g network. the phone was getting only 2g network. when i checked the imei i wsaw that it had the format 0 /01, i tried to fix it with any solutions but i couldnt, the phone was not even rooted before. i rooted it. tried lots of things but couldnt manage to fix anything.
if anyone knows how to restore the imei please tell me.
If you previous don't have a back-up, you're screwed. You need a special tool box to insert the IMEI back. As the phone progress, it becoming increasingly hard to restore IMEI by just ADB. Plus its against forum rule.

[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.
So I recently noticed that my T999 was not getting any 3g H+ signals and was stuck on edge. The 3g was working in Taiwan (I lent it to my mom who has since upgraded) so I'm guessing it is some sort of authentication problem. Here is what I tried:
When I got back to the states I installed a few custom roms before noticing that the 3g wasn't working. It's possible that the qcn was fine in Taiwan and got corrupted after I came back though I have no way to check this.
I odin'd back to the latest stock rom and it was still stuck on edge.
installed custom stock rom for 4.1.2 so I could access the qualcom usb menu
The IMEI is fine but the IMEI SV is 12 which I don't know if it is correct. So I tried NV item reader writer and made a backup.
I then downloaded an NV items file which is supposed to fix 3g issues after an imei repair (which I did not do) from a thread in gsmhosting.com and wrote that into my device which did not work and is still stuck on edge.
tried same thing with QPST
tried to install SQS3 QCN generator but the author of that program has disabled the server so I can't install it and so cannot repair my IMEI
tested the nano sim card on an T mobile SGS vibrant and a Tmobile lumia 521. Both got 3g.
The nano sim is slightly thinner than a micro sim and the adapter does not compensate for thickness though I don't know if this really matters and I don't have an adapter that does compensate.
At this point I am almost contemplating buying a new IMEI number to see if that does anything. Any help is greatly appreciated.
