[Q] Sim card problem

Hello,
I bought my Note 3 mobile and decided to flash C-Rom!
At the morning of one day I flashed the rom successfully. Later I installed all apps I wanted. I have my phone rebooted a lot of times with no problem. Some time at the afternoon of the same day I pick up the phone to stare at it! I activated the LTE option and deactivate it again. This was not the first time of doing it! After that the network signal was missing! I rebooted the phone, but it doesn't ask me for a PIN any more. I used my sim at another phone and it asked for a PIN. I used another SIM at my phone but it didn't ask for a PIN.
After dialing *#06# at Dialer a popup dialog shows up. The title of this dialog is MEID and the content is B0000000!
At settings>About phone>Status> the MEID is full of zeroes but the IMEI seems OK.
At the same screen i see the following:
Network - Searcing for Service
Mobile network type - Unknown
Mobile netwok state - Disconected
Service state - Out of service
My phone number - Unknown
MIN - Unknown
PRL version - Uknown
ICCID - Unknown
Thanks everyone in advance

Very strange.... without doing anything like flashing stock or modem?????

The reason is unknown but it seems like your phone lost a valid IMEI/baseband.
Can you check the Baseband version?
Try to flash the stock firmware, or flash the baseband for your device.

The problem suddenly appeared and that's what makes me feel uncomfortable. The baseband number is N9005XXUENC2. I will try to flash whole firmware, but does anyone know how can I flash only the baseband? I don't want to stay with the original ROM!

Extract modem.bin and NON-HLOS.BIN files from the stock firmware, and flash via Odin.

It is my first Samsung. Could you be more specific? How can I extract those? Can you guide me through?

Do you have the stock firmware file already?

Finally I was able to solve the problem. It is a problem with C-Rom and 4g option. I am going to write a new reply by tomorrow and also to the forum. I appreciate the help guys.
Thanks a lot

The problem is with the LTE activation/deactivation.
I am from Greece with COSMOTE provider. Here, in Greece, at the moment we have to pay an extra fee to the provider in order to have the option of using 4g. The steps as I believe are the following:
1). I am not paying this fee at the moment so I am not able to use 4g.
2). I activate 4g and immediately I deactivated it. I did not want to open it, just touching the selection at the notifications. This option is at the notifications when you slide down the notification bar using 2 fingers.
3). Then the signal goes off and I had to re-flash stock rom once again before flashing the custom rom. The problem has to do only with the signal and everything else works as charm in the C-ROM.
The C-ROM version which has this problem is this C-RoM-KK-v7.1-20140622-hlte.zip

[Q] [q] htc hd2 signal problem

Hi,
I need to know what is with my HTC.
I have the EU version of T-Mobile, Vodafone sim (I was in her shop to change. For new) In another phone runs normally.
So the problem is as follows. I had android 4.0.4 and there ceased to function signal, I put the phone to backup the default Windows Mobile 5.6 with official rom and radio (the latest version). The problem persists. But if I give another card to phone eg. O2, T-Mobile phone works normally. Vodafone card was connected corretly to this time. But not is'nt working.
I tried to choose network manually unfortunately found phone networks - click has been uploaded window "Registration in the network ..." A top searches for signal ... And it makes all the time and after a minute my phone reports that the network is not available. Coverage is here - H, G.
There is no problem in setting mobile network?
Or in ROM, SPL and another?
Thanks for the answer!

does your Vodafone sim work on other phones?
Edit; sorry, you said it did.
Odd that your first one just stopped working.
Which ics rom was it?
which (h)spl was/is installed?
more details please.

[Q] Network register problem, GSM, 3G connectivity issues...

hi to all,
anyone please help me since i got my note 4 n910f i have an issue with it. It doesn't connect to gsm/3g network. Its unlocked/not stolen/not blacklisted etc. The weirdest thing is that after flashing firmware it recognizes sim card and register and just for only one single FIRST time i can even make a call but that's it after ending that call whatever i do it won't register to network or if i manually select search network it keeps searching but won't connect even if it stopped searching after long time it won't show its network name though it show WITHOUT sim card. i have changed sim cards. even used professional help by writing some qcn files etc but after writing those i still got same problem i.e; can call for first time after writing qcn but that will be last.
You people don't think that it calls for first time then won't call until i flash new firmware.
Oh BTW there is another problem whenever i flash lollipop it won't detect in windows but detect every mode on kitkat.

[Q] Voice: out of service. S5-G900F

someone save me please... I've been struggle for two weeks...
I'm using S5-G900F, its a Hongkong version, and I'm currently in UK with giffgaff. last month I tried few new rom and then I can't use voice service any more. However I still have internet. Some detail below:
APN
1. I 100% sure its not an APN problem
IMEI
1. IMEI seems ok, start 4 digit 3524****
SIM card related
1. At first I assume it's a SIM card related problem, I tried 2 SIM with different ISP, neither work.
2. Also, I put those 2 SIM on my iphone4 to verify that the SIM is good, and both card work.
3. I also checked the SIM card cable, I put one piece of paper above the SIM to tight the contact, still doesn't work.
Phone related
1. Before I brought the phone, I had check the bands it supports, and it is capable to used here. And the phone work perfect (well, with stock firmware its really slow) before everything happen.
2. Since I brought this phone in HK and now I'm in UK, I tried to flash both latest UK and HK firmware (lollipop), neither work.
3. I also tried only flash baseband from that two firmware plus one old-version baseband. none work.
4. For those flash mentioned above, I do full wipe.
Rom
The rom I tried list below (in time sequence)
1. XtreStoLite (the BL/baseband is extract from Brazil stock firmware. After that problem occur, but I didn't realize)
2. CM12 (this two are all from this forum)
3. TGY-G900FZHU1BOA1-20150120092320 (HK stock firmware, 5.0. Try to recovery the voice)
4. BTU-G900FXXU1BOB7-20150223084756 (UK stock firmware, 5.0. Still trying)
5. Also 2 baseband/BL from XtreStoLite thread (Another is an old-version. Still).
So now for everyday, I had to carry two phone... one just to make sure I don miss any call.... I have tried and still no clue... really need some help here.... Help please...

Can anyone help me please....

Was the phone service working for you before you tried a new ROM?
I have the same issue. Can't make or recieve calls. Internet is working though.
When you try to call someone, do you get 'call ended' message almost immediately after dialing out?
Also, when you go to phone / settings / additional settings (or more settings) - does the 'network or sim card error' pop up?
Can't figure this out... Hopefully someone would be able to point us to right direction, other than to replace it
And of course I did a factory reset, new roms, modems, everything there is to try. nothing helped

could it be because of Region Locking? Maybe it's locked again after flashing?. I want to buy this phone but I am not sure if it will get region locked again after it gets updated or custom flashed.

Yes, before I flash those ROM everything goes well. I'm currently using CM12 so I don't have the setting you mention. But anyway I never seen that pop message before. I guess the SIM card work good as the phone can connect to the internet (not wifi, cellular internet).

CustomRom or stock?

Same problem,
You got any solution?

Hi all,
The problem is with the baseband. Unlocking the bootloader corrupts the EFS for some devices like mine, though the IMEI was shown properly.
I had to totally restore my baseband, calls are fine now even on non-VoLTE network.
Check out this thread.
https://forum.xda-developers.com/k6-power/how-to/guide-restore-baseband-k6-note-imei-t4007861
And for the second SIM issue which a few people experience:
1. In stock ROM, primary mobile data SIM is set to LTE/WCDMA/GSM by default, but that is not the case with custom ROM (atleast in my case).
2. To get the second SIM slot work properly, manually set the network to GSM for your second slot (in case if your second slot is not your primary mobile data slot).
3. If you have changed the primary data SIM to your second slot, you have to set the first slot to GSM manually from network settings (this will not change automatically) and set your second slot to LTE/WCDMA/GSM. Your second slot will receive signal and connect to the network now.
Thanks,
tfr.
