Well, I have a z play bike, upgraded to version 7.1.1 of the Android, patch from July 1, 2017.
My device recognizes my SIM card and the number appears on the same tab, but it is out of service!
I picked up my wife's device for a configuration question.
Moving from here and there, looking and comparing, I saw that everything was really identical, taking something out.
Entering the phone information by typing the code * # 4636 # * # *, I saw that the only thing that differs from my wife's is the option "Cellular radio power" that my device is not active!
Another error was that when I try to make a call, it appears that I have to turn off the airplane mode to make a call being that it is already disconnected and at the moment of the call, on top of the name of the person to whom I am calling, a quick "Radio off" message. I entered the phone application and went to settings> call accounts> Select my chip (TIM), yes it is written TIM !!> but when I click on additional settings it the configuration error of the call (Network error or SIM card). I already tested other chips and nothing, I believe it is the option that I can not activate. Can anyone give me a light ? Sorry my English, I'm Brazilian and I can not understand the language very much. Thank you!
Did you try to hard reset?

Yes, I did. I have already upgraded to version 7.1.1, I have already returned to version 7.0. Before it was in version 6.0 and also did not work. The funny thing is that he reads my chip and shows up to my phone number. When I try to make a call, he asks to turn off the airplane mode and above the name of the person I'm calling the radio appears disabled. I believe it is the power option of the cellular radio that is not activated! One thing is for sure, it is not software. Any idea ?
I litte noob in hardware problems, i have two assumptions, the first thing i think is if install a custom rom and then flash stock rom and lose IMEI (to check type in dialer *#06#*) if this happens and you don't have a EFS Backup, sorry but theres nothing to you make, the only way is changing the motherboard, my second teory is can a problem from Tim Sim Card, you to try others sim cards and see if working in your device, if its works just go in Tim Store and pass your number to other sim card
Obs : i brazillian too and in past i have a lot problems with tim sim card.

If nothing works you can make a last software try, and reinstall all the modem part of system, taked from stock image

HI!
Can anyone out there help me with a registry tweak to display in tf3d the active line of my phone network?
I mean when my "dual SIM" it's selected on business number to show me business or the number instead of VF-RO, and when i change to other line to display the number or personal.
Thank you!
Dual Sim

Thanks for the answer, but I do not use sim adapter. I have both numbers on the same sim, and I have updated the numbers in home and business menu but it's still show up the operator name.
In the operator menu I have option "display current number". This will show me the number but only for 3 sec.
I wonder if I can find that regisrty from "dual number menu" and place them in RIL or something...

Hi. I am not sure how exactly this is achieved, but it is available in Vic's ROMs. So, you could install one of those (which are actually quite good in my opinion). You could also take a backup of your device with this ROM (e.g. with SPB backup) and then, after flashing the ROM of your choice, you could make a restore using ROM upgrade mode. This will keep the functionality of displaying the active line name from your 2in1 SIM.

Let me guess...
You've discovered some hidden menus recently by typing codes in the dialer and find out this one: *#*#4636#*#* that open a "Testing" screen showing options like this:
Phone Information
Battery Information
Usage Statistics
Wi-Fi Information
Then you went to Phone Information
Tried some options (maybe played with SMSC:_________Update / Refresh ) but that was not doing anything so you exited the menu.....
after a while you wanted to send a text or someone was asking you "Did you got my text?" and you didn't....
Here's what hapened: Accidentaly you erased from your phone the "Messaging Center Number" wich is responsible for giving your phone the access to the SMS/MMS central of your provider.....resulting in loosing the ability to send/receive messages.
Don't worry, after having navigated XDA Forums I finally found my way to make it work again (yes that's because I did it that I now now it).
By the way, even if you Factory reset, flash a new rom/radio/kernel that mistake is gonna stay. You need to enter the number again.
in the *#*#4636#*#* hidden menu,
scroll down to "SMSC:"
in the box type: 0791715097960300
press the "Update" / "Mettre à Jour" (first button)
Now exit and Reboot the phone.
To test it, don't try to resend an old test message as it contain old message center number. I even suggest to delete previous text messages from your inbox if possible.
If it worked, everything should be fine by now. (you can even kudo me for this loll)
NOTE:
The real Roger Center number is +17057969300
the thing is that it need to be Encrypted in Hexadecimal PDU format.
(user MarcusVanSciver on XDA shown that link in thread http://forum.xda-developers.com/showthread.php?t=1412261)
That was for Orange Network (european have 8 number to phone number instead of 7 so I had to add a 0 at the end to make it work for Rogers)
after Encryption the number was now: 0791715097960300
This worked for ROGERS, the trick could maybe work for other networks but I can not validate the info. (but for sure this will not be the same number)
This had been tested with stock rom and Custom Rom With Custom Radio and Custom Kernel.

Hey man, this might be a bit old for you but i just got a galaxy nexus. I am having the outgoing text issue. I've tried that number and everytime i hit update it just says update error. Think you mightbe able to help me?
Damn this doesn't work for me
To program the SMSC (Text Messaging) number on Android devices, please follow these steps:
Go to the phone application.
From the phone application, press *#*#4636#*#*. (You will have to press the Call or Send button after entering this code in for some Android devices).
Tap on Phone Information
Scroll to the bottom to where it says SMSC and enter this number exactly as you see on this page (including all symbols): +17057969300
Press Update.
I've been testing this phone for a while and it seems like a lot of the menus have been disabled. I'm creating a list of what works and what doesn't in these next few posts.
Note: I do not provide any support with the use of these codes. The thread is for documentation purposes.
What works:
5689#*993# (HiddenMenu) - Device Testing Menu
##27263# (##BRAND#) - Removes any carrier branding and redetects the carrier based on (NV registry/RUIM/SIM?).
Note: Useful if flashing to Boost Mobile or similar carrier.
##72786# (##?????#) - Resets provisioning and makes phone reactivate.
Useful if you are having network issues. Sprint recommends this if you ever change your services or phone number.
##72786# (##UPDATE#) - Updates cellular data profile and configures service. Also causes a firmware update check.
##786# (##RTN#) - Factory reset. Erases everything!!! RTN is short for return?
##3424# (##DIAG#) - Pulls up DIAG menu with option to enable or disable.
Selecting "Enable" allows Qualcomm Mode when the phone is set to "Charging mode" while ADB debugging is disabled.
##3282# (##DATA#) - Pulls up cellular data settings menu. You can view settings by choosing options and this also lets you adjust PRL settings with your MSL code.
##33284# (##DEBUG#) - Pulls up reception statistics, connectivity, and misc device information.
##564# (##LOG#) - System Error Log. Have options to clear or copy to storage. Viewing it will show Last kmsg, crash log, or ANR log.
Dial Codes That Don't Work
These are the dial codes that are not working on our model.
##PST#
Reserved
I've reserved this post for any comments I may have about the posts above.
Here is an updated list of what works.
What works:
##27263# Removes any branding (sprint) and resets phone to update branding. (useful if flashing to boost or other carrier) (##BRAND#) Reboots phone.
##72786# Resets provisioning and makes phone reactivate. Useful if you are having network issues. Sprint recommends this if you ever change your services or phone number. Reboots phone.
##873283# Updates data profile and configures service - Causes a firmware update check (##UPDATE#) Reboots phone.
##786# Factory reset. Erases everything!!! (##RTN#) Reboots phone.
##3424# Allows Qualcomm Mode while in Charging mode when ADB is disabled. (##DIAG#)

##33284# Network debugging menu. Gives information about network status. ##DEBUG#

##72786# stands for ##SCRTN# which my best guess is sprint carrier return. or in other words carrier settings reset.

Try taking out the sim card and booting up. Then reinsert the sim card and reboot.

Did you solved it? same problem here!
If you have invalid sim on another carrier, try inserting the sprint sim and going to system update menu, then hit unlock uicc and it will reboot, then again go to system update and hit update profile then update prl. Then power off and insert the other sim and it should recognize it. Tell me if it works.

You have to get the UICC Profile Update from Sprint.... Call the International Team or chat with them online and ask to be UICC unlock, if asked why, you're about to travel abroad... This UICC Update might affect the Domestic Unlock. At one point my device was domestically unlock, but now it isn't. (Maybe because I did a hard reset.) **Never Reset After Unlock, I learned the hard way lol

Thanks I got it unlocked finally again from sprint...
Other sims are working fine..
When I insert ATT sim card then if network mode is automatic then it shows 3G always and speed is too low tested with speedtest. If I change network mode to LTE-CDMA option then speed test is 4-5mbps but then calling does not work.. When i dial any no with LTE-CDMA mode then it says sim is not valid or there is no sim.
Will ATT not work fully with LTE on automatic mode on sprint LG G6?
Please help.
Thanks in advance.
So here is how it all started. One day i woke up and my phone was continuously restarting and just got stuck on wifi turning on. This is a very common problem and is said to be a hardware issue. A common fix to this, is to open the device and put a couple pieces of paper on the wifi chip to press it against the motherboard. This fixes the problem for most. So this is what i did. But for me, now it identified all the networks in the area but when i connect to a network, it just says "saved"or sometimes "wifi connection failure". The restarting issue is completely gone. I have tried factory reset but no luck. I was unable to find people with similar issue so any help would be highly appreciated!!
I am using android 6.0
previously before adding the papers, the mac address also changed to 02:00:00:00:00:00 but now its back to normal.. but not connecting to wifi.. It just says "connecting" and then "saved".
Please anyone? I am still unable to solve this issue!! ::crying:
BUMP!
Same Issue
Did you find a fix? Im still facing the same issue.
I got the same issue but only with one router. I believe there is something with the router not G3 itself.

This problem arrises due to installing custom rom and restoring qcn and it could not be solved by restoring back to stock etc.
Simple solution to that problem is
First you need to install any Marshmallow firmware custom rom fulmics etc.
Then go to hidden menu
1- on dial pad : *#546368#*850# (850 is for D850 and write for your model )
2- find and click SCV Menu it should be 3rd one
3-click on CRCWIZARD Test
4-click the tab Auto MID
5- uncheck IMEI in MID settings
6- click generate to generate your new MAC's
7- click MID write
8-Click Refresh to be sure that you changed MAC adress
9-Rebbot phone to take effect!
After reboot you will be able to connect any wifi without having wifi saved problem or connection failure

Hello
Here is my issue: I buy a second hand S4 mini plus (i9195i - serrannoveltexx) for its compact size and by considering the simple usage I make of my phone. So far I do not use so much data so I don't care about used network, but recently I start using more data and I notice I never get LTE. I change carrier because I was thinking LTE-cover was the problem, but not. I still have no LTE. So below, is more or less everything I tested:
at beginning, I was few months on stockrom. Then I go to LineageOs 14.1 (thank to dev for the work). In both case I'm almost sure I had no LTE (I checked APN and 4g/3g/2g enable in network menu. And I start to check LTE-cover of each carrier . And I very start to check band used by the different carrier).
I change carrier and I check APN once more : still no LTE.
I come back to stockrom (just in case) : still no LTE
I switch SIM card : my sim card in Oneplus One get LTE and sim-card of my friend do not get LTE with my phone. (So I try copying manually the exact same APN : not working)
I try to flash old stockrom and let OTA update make the work : no LTE
I make necessary to have CSC=XEF as I am in France.
I try flash with pit-file and re-partition.
At the end, the best thing I succes to get was H+ (and for some reason I have it when I clear and restore the NV in 'service menu'), so :
-I contact samsung and they recommend me to go to one of their after-sales office.
-I contact my seller and he tells me that LTE works in germany.
Does someone has an idea how to solve this issue ? something that could block LTE ?
Next step I have in mind :
-I read some topic where double-flash within wipe and clear factory could help (but I have the feeling that will not work because it is more or less what have done to change CSC)
-I would check the activated LTE bands (but in 'service menu', I find a LTE band hexa-value that meet with explanation of binary description (another thread in XDA - thanks to people who write this tuto))
-I am considering go back to LineageOS but 15.
-I am considering to change LTE antenna (this is part of middle frame - I notice if I enable Data when i have 'service menu' opened, the phone seems to looking for LTE first, so I am not sure this is only SW problem ... do you think it is possible that only LTE part of such a SystemOnChip could die ?)
Thank by advance for your help
Best regards

And I start to check LTE-cover of each carrier . And I very start to check band used by the different carrier).
I change carrier and I check APN once more : still no LTE.
I come back to stockrom (just in case) : still no LTE
I switch SIM card : my sim card in Oneplus One get LTE and sim-card of my friend do not get LTE with my phone. (So I try copying manually the exact same APN : not working)
I try to flash old stockrom and let OTA update make the work : no LTE
I make necessary to have CSC=XEF as I am in France.
I try flash with pit-file and re-partition.
At the end, the best thing I succes to get was H+ (and for some reason I have it when I clear and restore the NV in 'service menu'), so :
-I contact samsung and they recommend me to go to one of their after-sales office.
-I contact my seller and he tells me that LTE works in germany.
Does someone has an idea how to solve this issue ? something that could block LTE ?
Next step I have in mind :
-I read some topic where double-flash within wipe and clear factory could help (but I have the feeling that will not work because it is more or less what have done to change CSC)
-I would check the activated LTE bands (but in 'service menu', I find a LTE band hexa-value that meet with explanation of binary description (another thread in XDA - thanks to people who write this tuto))
-I am considering go back to LineageOS but 15.
-I am considering to change LTE antenna (this is part of middle frame - I notice if I enable Data when i have 'service menu' opened, the phone seems to looking for LTE first, so I am not sure this is only SW problem ... do you think it is possible that only LTE part of such a SystemOnChip could die ?)
Thank by advance for your help
Best regards

Some older Samsungs eg Note 1 had reception problems due to poor connection (possibly oxidised contacts) that could be fixed by simply tightening the screw a fraction that secures the pcb or antenna so it was grounded (from memory) properly, though of course it could be your actual antenna that has failed. (possible cleaning contacts might be worth a shot if tweaking screw doesn't fix)
(or modem/baseband issue if software, try flash again or try another version, backup your baseband radio settings first with twrp or an app)
edit: also try reset network settings before paying for new antenna (edit: though suppose flash with pit etc should have done this)
Hello,
Some news on the topic:
I try to tighten the screw and I also try to clean LTE antenna contacts : I use very very thin sandpaper (usually used to polish) to be sure there is no oxidation
I also make the mistake to erase all EFSs and EFS_Backup
Reminder : in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'NV backup test' / 'Erase all EFS 1/2/3' => So never do this if you have no backup
After this, I lost my IMEI... no way to restore it with IMEI tool... What a pity because I was hoping to only set my IMEI in order to test with completely clear EFS. Finally I restore my IMEI thank to my very first TWRP backup (thank to TWRP team that it works for me because it seems not always the case)
I try 3 times consecutive reset factory : 2 in recovery and 1 in settings.
I try to activate new LTE band but it seems that as I am in StockRom, update is not properly done.
In fact just after the work with QSPT and QXDM, I can find the nez band in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'LTE band & CA combination. but after reboot I lose it. Probably I'll make the work one more time after coming back to LineageOS.
One last thing I want to try is going in front of 4G antenna and check signal power seen by the phone but I'm thinking this is not the true problem. I explain:
service menu (*#0011#) start to show Basic network information and if I force LTE_only (in service menu), I can observe these information. strange thing I see are sometime state goes to 'TAU_init' (and also 'deregistr' or 'register'). Some other time MCC-MNC goes to 151515-1515. I have the feeling the phone is trying to connect but something goes wrong and I do not know what...
if someone has an idea, I am still looking for.
Best regards
