I've tried unlocking my AT&T Galaxy Note 2 using service mode. I downgraded the phones modem to the 4.1.1 version and it worked. I used my metroPCS sim card and the phone did not ask for the code but it said phone not allowed MM#6. When I try to call someone it says emergency calls only. I was wondering if it is because the phone is still under contract or because I'm supposed to use a blank sim card and not one thats already been used. Please help.
Hey I have my sim unlocked I did it using the hidden menu method I have used it on simple and more recently metro. I got a new Nexus so this is now my backup. The other day I put my girls tmo sim in and it worked fine but today I put my mother's metro sim in and it wouldn't get a signal. But it didn't say insert sim. So did I inadvertently relock my phone to tmo by putting a tmo sim in it?
Also I am on cm 12.1 and I don't have a PC to Odin back to stock so is there a way to unlock the sim without having to go back to stock?
No re lock is possible.
There's no way you can relock your phone , it doesn't work that way, once is unlocked stays forever.
Hii to all
Now I have to say something for most users who have bought it
over some carrier on contract like I have done
I asked when I was buying K5 PLUS are all sim slots locked to the provider I bought from?
She checked it for me on paper and said, yes, the phone can only be used with the carrier
SIM cards only and that was for both slots...
Well I was lazy to check when I got home if she was right or wrong...sometimes they do
not have the right information
But today after QFIL and after i Installed the firmware with QFIL
I tried a different carrier sim card in the sim slot 2 and it works
Both cards works
Tested so far..
So, maybe a try for someone locked to some carrier..
Good luck with flashing and just do it exactly step by step all of
you should not have any issues
Hey I have a att note 10 I recently got unlocked with a unlock code. I put in a Verizon sim card and service works but the carrier profile and apps aren't switching to Verizon from att.
I got the att note 10 unlocked by unlock service that sent me the unlock code.
I'm not sure what to do iv factory reset the device multiple times and I can't seem to get the phone to switch to Verizon software like the boot screen showing Verizon and all the Verizon apps so I can get wifi calling working.
I tried this before with smooth success with a TMobile note 9 that I got unlocked and installed a Verizon sim card then it immediately prompts me to reboot the device to switch all the new sim card carrier settings and apps.
Good day everyone!
I recently got a new phone (Galaxy S21), and I saw that you can bring your own phone to Tracfone, so I gave my Verizon S9 (SM-G960U) to my wife (to upgrade her old Samsung Tracfone phone).
We bought and installed the Tracfone SIM card and everything seemed to be working (she could make and take phone calls).
Little did I realize that Tracfone actually also uses WiFi for phone calls, and thus making and taking calls was not using Tracfone's network while connected to WiFi.
When we started researching why her phone did not work outside the home, we found that the CSC is still set to VZW.
This S9 has the latest April 2021 security update from Verizon (Android 10).
I downloaded an older stock Tracfone ROM, but Odin fails with an Auth error (presumably because the phone is not unlocked nor rooted, and the bootloader is locked).
I also tried just flashing the CSC with a Tracfone CSC, but it also failed with an Auth error.
All of the research I have done to this point indicates that Samsung makes flashing Android 10 Galaxy phones very difficult, and I suspect that I am screwed.
Should I put the Verizon SIM card back in and beg Verizon support for an unlock code? Will that even help?
Why doesn't the Tracfone SIM card override the VZW CSC? I thought the SIM card would take precedence.
Thank you in advance, and I hope I am not repeating another thread (I searched, but I couldn't find anything related to changing CSC or rooting a Samsung Galaxy phone running Android 10).
P.S. I have no objections to performing a factory reset of the phone if it will help.
P.P.S. I would like to run the stock Tracfone S9 image so my wife can get the OTA updates, but I'm willing to do whatever to get it working (I would even be happy with running the existing VZW firmware as long as it works).
