[Q] Stock 4.4.2 on i9192: mobile signature not working

Hello,
I have a Samsung S4 mini duos. I am not sure where it was purchased, probably UK or DE.
I updated it to stock 4.4.2 from sammobile. Tried several firmwares, but WiFi was not working. These are not working: Sri lanka, Russia, New zealand. The only one I managed to support Wifi was this Panama ROM:
http://www.sammobile.com/firmwares/download/40033/I9192UBUCNG2_I9192UUBCNG2_TPA.zip/
I have also used CSC to set it to SEB (baltics).
Now everything is working fine more or less (battery life is bad on 3G, good on 2G), however I am unable to get mobile signature working. It was working fine on stock rooted 4.2.2. The card is inserted to SIM2, it is working properly: sending messages, calling, receiving calls. However, whenever I try to use mobile signature, I am asked by SMS toolkit (I guess) to check my data. When I click OK, it says ERROR DF 19 00.
My operator says this error is related to phone's software (I have tried it on other phone and it works). Anyone knows what is happening and how do I fix this?
Also are there any other stock roms available, closer to baltic states or UK/DE at least? Maybe Panama has some weird GSM settings.
And why does WiFi not work with other roms, like Russian?
Current version information is attached bellow.

Hi dude i pass for the same problem and the only you have to do is reflash the rom throu odin, for example i flash once the russian one and i did not have wifi working the first time, so i reflash it again and "voila" wifi start working,
look you can flash this rom http://forum.xda-developers.com/galaxy-s4-mini/development/s5-s4-mini-t2987500 via recovery and see if its work for you, use philz recovery to flash it, and in the installation process there will be a part where your select you CSC, and of course this rom have a very good battery improves Gl mate!

Flash rusian firmware until the baseband change
Power off phone using power key a menu
Restart in Odin mode using combo keys power home vol down
Flash firmware in ap
Let it boot and check if has changed

it is strange, but shutting down before flashing actually helped right away.
So now I am running stock russian (EN menu) firmware, however mobile signature is still not working.
Anyone familiar with SIM toolkit errors? Error DF 02 00 or DF 19 00.
Is there a log somewhere?

Sim Unlocked phone got locked again. Please help!

Guys, I unlocked my Sprint Note 4 successfully on 5.0.1 (OF5) using the idone app. Later I Odin it to stock COG5 5.1.1 tar. Once I did that, my hotspot and roaming options disappeared from settings. In order to get data working on my operator (non US CDMA), I had to write a dummy NV Dump and had to change few other parameters (trial n error). I finally got data working but I changed too many parameters. So I decided to ##RTN#, so that I can reset back those parameters and start fresh from begining.
Right after the reboot, it started to display "invalid card". I tried different sim but same result. I tried to Odin back to stock COG5 tar but it didnt help. Now that I'm on 5.1.1, I'm unable to use idone app to sim unlock again. And since I'm on COG5 firmware, cant downgrade as well.
Please help me out guys.

You absolutely CAN use the idone app on OG5. You need to flash that OG5 file from Odin, flash TWRP from ODin, then the Beast Kernel and superuser from recovery. As long as you have the IMEI file from buying your unlock on your SD, it will unlock again. I went through the same issue with one of my Notes just yesterday. You can use the unlock app a million times as long as it's on the same device as the IMEI as originally paid and unlocked. It's a little bit of work, however I did all from A to Z in 15 minutes. Good luck, but it CAN be done. Good luck, and happy flashing.

It worked. Thanks a lot.
Now in the trouble of getting hotspot to work. No hotspot option under my settings. Didnt work even with idone apps.

I see no direct option for hotspot under settings. But i can get to hotspot settings using idone app. But no devices are able to connect note 4 hotspot. It keeps on showing connecting and time outs. Please help me enable native hotspot.

No Signal - won't connect to a network...

Picked up a used AT&T Note 5 recently, everything works except it won't connect to the T-Mobile network. I had previously bought a used(white) AT&T Note 5, factory reset it, put in my t-mobile SIM and bam, I'm up and running.
But with this (black) one I've tried just about everything, adding APN, check IMEI, etc....no dice. Even tried the T-mobile customer service. They tried & checked everything, no go. They even saw the device history and it was running on t-mobile just a couple months ago with the previous owner. I've even ran a ping test and turned the radio off & on in the diagnostics *#*#4636#*#*.
After investigating other threads it seems it could possibly be Marshmallow PE6 that screwed up the radio? But I would think it had been running on that previously.
Any other ideas?

Just try downloading a different firmware(older) and pull the modem.bin out of the tar file and then re-zip it again into a modem.tar file so it can be flashed with odin but don't try going to far back like if you're on Marshmallow don't try flashing a modem from Lollipop because it won't work.. I use 7zip for the extracting and zipping of files.

Well, the plot thickens.
When I checked the IMEI before purchase on Swappa it said all was good. However, they couldn't identify the type or provider of the phone. I didn't think much of it at the time. So I decided to double check the IMEI on a different 2 other checking sights last night and I got the following info(from both!):

Clicked "Network Check" and it said: "IMEI not found on database."
Wtf? Can this be fixed? Is this causing my network issue?

I also checked the IMEI on the back cover, and it states it's clean, not blacklisted and is for an AT&T Note 5.
Anyone restore an IMEI?

Messing with the IMEI is illegal! Are you sure you didn't buy a fake phone? Do you have a picture of the front of the phone?

Download an app called phone info from the play store over wifi and see if the settings match what they're supposed to for the phone. Is there a sim card in the phone?
http://m.gsmarena.com/samsung_galaxy_note5-7431.php

Yes it recognizes the SIM but still, no network found.
Cosmetically nice phone, guess I'll re-sell for parts.
Thanks anyway, appreciate the responses.

For tmoble you have to unlock it.

Bought in USA, can do something to use in EU?

Hey,
I bought an LG G7 ThinQ (LMG710TM) in the USA, and i does not connect to the LTE/4G mobile data network here in Hungary. Since it's a T-mobile version i thought if i could unlock it, it may work (i can use my Telekom SIM since the beggining to call/send msg), but i can't get the unlock bin trough LG site, because it says it's an LMG710TMP version which is unlockable, but the phone itself says it just te TM version withouth the P on the end.
Anyways should I even bother to try to unlock it, because i didn't really find any infos which frequencies are supported by my own device, so it maybe just blocked by the software or not.
Thanks!!

It's not rooted right?
Enter the service menu and check the bands. If it says "SUCCESS" then that band is supported. If it says "FAIL" it's not.
Bands 2, 4 and 12 are the ones usually used with GSM LTE in America.

Thank you for your help!
And yes, it's not rooted.
I checked the service menu, the listed(pic1,pic2) bands are all working, at least it said "SUCCESS" when i clicked on them, and in Hungary they use band 3,7 and 20.
I set it on 3, tried to reinsert simcard and restart phone, and airplane mode etc,etc little tricks to get it work, but still no mobile data.
The weird thing i found is the LTE Carrier Aggregation(pic3,pic4). It says what is says on the picture and i can't change it, because it tells me i need to restart my phone. I did it but no changes, so it just stuck at those options. I suspect the problem is there for some reasons that i don't know.
On pic5/pic6 those are some infos about the LTE stuff, sometimes it said Not Supported Mode at the Mode Pref, sometimes it said Automatic. Sadly i don't really know what that means, maybe it will provide some infos to you.

Did you contact the mobile provider and ask them to add your phone's IMEI to their service?
In USA, some people who bought the LG unlocked international phones did not have mobile data until they called the carrier and had them register the IMEI number.

You'll most likely need to setup your APN manually. Go to settings-network and add APN info for your provider there!

Unable to flash the desired carrier stock ROM on Galaxy S20 SM-G981U with Odin

I have a model S20 SM-G981U that is carrier locked to SPR. But it was flashed to the latest Metro rom with Odin accidently. My ultimate goal is to carrier unlock the phone.
Now with the Metro rom, it doesn't come with any carrier unlock app to unlock the phone. I tried flashing the phone back to Sprint using the following ROM:
Download SM-G981U / Galaxy S20 5G SM-G981U SPR in Samfw - Samsung firmware download
SM-G981U / Galaxy S20 5G SM-G981U SPR samsung firmware download all model, lastest, fast update, completely free and fast speed in Samfw.com ✅
samfw.com
Odin shows that the flashing was successful, and the phone was successfully factory reset after the flash.

However, the phone still shows that it is on Metro after everything is finished:
What am I doing wrong??
TIA for any help or advise you can give.

The phone detects the CSC to use from the SIM. Do you have Metro SIM?

Oh that was a brilliant suggestion, ShaDis. I had hoped that it was the case. I just removed the Sim card that was in it, a Cricket Wireless sim, and tried reflashing the phone and the same thing happened It's still showing the Metro logo when the phone starts and the same "TMK/TMK/SPR" as the provider software in the Software info screen.

Did you ever get a solution to this issue? I have the same problem with an accidental metro pcs flahs. Thanks

I do not understand what the problem is. Update was successful. What is wrong?

There's no such thing as an "accidental metro pcs flash". The Metro model has the exact same model number as the Sprint model, and the firmware is also identical.
Since T-Mobile bought Sprint, Sprint's devices have automatically been made compatible with T-Mobile. That means that when you insert a T-Mobile SIM into a Sprint device (even if it's still SIM locked), it's gonna give you the popup prompt to "reboot to apply new carrier settings" (as if it were SIM unlocked). That's because it no longer needs to be unlocked in order to be used on T-Mobile.
And, since T-Mobile owns Metro, the same thing probably goes for a Metro SIM.

I found out that they all use the same flash firmware files. When the phone detects a sim card in it, it would show the appropriate carrier's logo. My phone was locked to Sprint previously, so I couldn't get it unlocked by calling T-mobile. So I'm stuck with a phone that will only work with T-Mobile

I was on the phone with T-Mobile customer service for a couple of hours and they kept transferring me back and forth. I gave up with T-mobile. Are you that wise man who knows the answer to my quest?
