Hello folks,
I asked that question a while ago in VomerGuides thread, however the problem wasn't resolved.
The thing is that when I got my sim card and phone from Vodafone (in the Netherlands), whenever I went abroad the sim card was working properly. Then I unlocked my bootloader, s-offed, rooted, achieved super CID and installed custom recovery. After this point whenever I go abroad, and I try to join a network within the particular country the phone says that the sim card doesn't support the selected network.
I talked with vodafone, they said everything is fine with them. They also gave me new simcard in case there was a problem with the old one - nothing has changed. I still have the problem...
Any ideas whether the problem is actually caused by all the manipulations I did, or there is something else?
[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.
Hello I have an unlocked SGH-T989D phone but the problem is it will only detect sim cards from Koodo even though it is unlocked, I've tried flashing many different roms and different radios but nothing is working. Currently on stock 4.0.4 /T 989UVLE1, yes the phone is unlocked I checked multiple times. Anyone know how to fix this?

How do you check if a phone is unlocked if any SIM you try from another company is not read by the phone?
I think you need to try the unlocking procedure again, I don't think it was properly unlocked

What method did you use to unlock it?
I did it with this (http://forum.xda-developers.com/showthread.php?t=2024514) and not a single time was I asked to check with the code that you have showed me
This IS for the T989 though, not sure if you can use it for the T989D or if it's different in a way.
Sorry that I can't help, I hope you get the answers you are looking for

My brother used that method a long time ago and he was able to use different carriers, but now nothing works but Koodo, and I never get asked for an unlock code, just says 'No SIM card'

Yeah, this phone will not ask you for an unlock code, if you follow the procedure correctly it will read any other SIM card on it's own
Try unlocking again with what you have, the stock 4.0.4 and UVLE1 combination, it should be the right one. Do the procedure again until it reads the SIM card you want.
Another possible problem could be that your SIM is damaged or not well placed. It happens to me when I try to fit a Micro SIM on it, if it is not well placed it will not detect it. Try using other SIMs or try it on other phones to see if your SIM is the problem

I tried unlocking it again, doesn't work, tried different sims, and still doesn't work, but those other sims work on different devices. Only the Koodo one works on mine, which was what it was locked to before unlocking.

Well in that case I'm all out of ideas.
One final question, when you insert a SIM on your T989D that is NOT Koodo, do you get an "Invalid SIM", "No SIM" or just an empty signal bar?

It says "No SIM card.|Emergency calls only"

My conclusion is that it's having a hard time reading the SIM card. When you put another companies SIM card in to a LOCKED phone, it will show as invalid SIM (sometimes it even shows signal but is unusable). Since it says "No SIM card", I believe it's more of a hardware problem than a software one.
All I can think of is try moving the SIM card around, turn on. If nothing changes turn it off and move a little again, the turn on and repeat until it reads it.
Apart from that, I have no clue what could be wrong with the phone.
Turn on your phone without any SIM. If you get the same message (No SIM card.|Emergency calls only|) then it is most definitely your phone not reading your SIM correctly. If you get Koodo signal WITHOUT any SIM inserted (which I doubt but it CAN happen) then that means you have a faulty SIM Card Reader on your phone.

It works on Koodo but only if the sim is inserted, also I tried moving the sim around and it still isn't reading. I think this is a software issue.

Sorry man, I'm all out of ideas. I mean I've experienced the problem with the "No Service" thing, but I basically fix it by switching to 2G since I know there are some areas that I can't get 3G coverage. As for your problem, it's basically not reading your SIM entirely (by either software or hardware issues) and I wouldn't know how to get around that.
Best of luck to you
As above really. Not really sure if it's a hardware or a software error here. I've read that the sim card readers can be a little fragile but there was no fuss during the removal so I would be surprised if that was the issue. What I'm wondering is if I've missed something when un-rooting my phone.
I was using a custom ROM, all working fine, but I've got a new phone so I decided to unroot my old one to sell on. I flashed my original firmware using the LG Flash Tool. Firmware file is "UK Vodafone 16G D85510A_00.kdz". It all went great as far as I could tell and I started upgrading. The final upgrade was the install of Marshmallow 6.0.
In order to find out if my phone was locked or not I put my Wife's SIM in. Rather than coming up and asking for an unlock code it simply stated that there was no SIM inserted. I thought that was potentially down to the wrong SIM being in but when I tried mine I was met with the same error.
Have I missed something? Did I need to change the baseband or something during the process?
Any help would be greatly appreciated.
Thanks
I've had kinda same problem since a couple of weeks ago...eventually SIM card gets read for a short while and get back to that No SIM card inserted state.
It has happened with any ROM as well as OG FW flashed through LG tool.
I haven't tried another SIM on my G3 but my SIM does work on other cell phones.
my vs985 is 1 yr old,rooted,all of a sudden my phone starts this problem with sim card non read..I've kdz,and tot all the way back to 10b,phone works great at10b,then stumproot(xda) and sim cards unreadable,or searching for global reading,it doesn't makeany difference to the setting of global or CDMA etc,after 10 times I still lose sim card when I root,I am on 10b root now however to twrp to jasmine or 47a I lose the sim.

You'll need to flash the 35b bootstack before you flash the ROM for things to work properly on 47a(not sure about jasmine). Read bullet point 5 for a link for the boostack... https://forum.xda-developers.com/ve...t/vs985-46a-stock-flashable-firmware-t3304365
did that.my phone started acting up that my sim was searching for global setting while on 47a for over a year,was giving a suggestion to tot back to stock the start over at 10b,my problem is whether I tot or kdz as soon as I root with stump(from xda site) I get sim non readable and searching for settings.this happens well before I even get to bootstocks,or ROMs.this is while trying to get it rooted on 10b,I've read many people are having a problem with sim cards..obviously tot/kdz gets me to stock with no problem,but trying to get from 10b upgraded is where the sim acts up..
as of now,it works and doesn't work.nothing to do with bootstacks,as I'm on 47a and it didn't work,I rebooted and it did work..then 2hrs later it screwed up again..not sure what it is....
download network settings guru apk and choose bands or *#*#4636#*#*
maybe your problem is something else...

OK...I really need to read more gooder So root is killing your signal somehow. Strange...
Can you grab some logs and post them please? Maybe a log before root when things are working, and one after root with a toggle of airplane mode a couple times to see if it kicks an error into the log and hopefully provide a lil info.
Also, does anything in the "about phone" settings info change after you root/lose service? For ex: unknown baseband, no imei, etc.
yes that's the main problem,I lose ime as well as phone number,and the phone says no sim card,and searching for global setting..if I reboot I may get sim card working but 9 out of 10 times the phone sim is unavailable.example is today,all day the phone worked great,then all of a sudden it lost sim card,no imie,phone number..after pulling battery and rebooting 3 times its working again.I'm on rooted 47a.
+1 For network signal guru, I had to unlock the other bands using that program. It took a few minutes.
It seems that the Verizon variants soft-lock the radio bands.
update this morning,when turning on my phone,it reads sim card searching for global settings,after pulling the battery it reboots and reads sim found,search for settings,global found,and phone works normal??, now if I tot to stock,phone is normal at 10b,then root,twrp etc and sim card will not read,after pulling battery it reads sim searching for global settings,4,5 seconds and phone is OK,then bootstacks,47a and lose sim,then pull battery and go thru the exact same thing,now I've gone to Verizon when sim is unreadable and with a new sim I still get unreadable sim,with no imie,no phone number??...
