Hello everybody !
I bought a Galaxy S6 Edge Model SM-G925F with Android version 5.0.1 ... everything is awesome but after 3 months the network deosn't work " EMERGENCY CALLS ONLY " i tried to fix the problem with adjust network settings but this is not the solution. i flashed the phone to Android 5.1.1 but no result,i found the IMEI in the Software isn't the same at the back of the phone. A friend tells me if i can root the phone and write the correct IMEI ... but i really need an opinion or solution of a professional here !
Model SM-G925F
Android version 5.1.1
Baseband G925FXXU2COH2

Where did you buy it as stolen or lost phones are soon blocked once reported and all you have is an expensive paperweight

hello xda !
I'm a C developper who just received his brand new Galaxy S3 i9305 4.1.2, my first android device !
And i love android. But i just realized it's simlocked and my provider bills 170€ (200$) to get an unlock code !
As i don't have that money and i don't wanna spend it unlocking my phone, i decided to downgrade my i9305 to 4.1.1, and to use the desimlock trick. I did it, using my provider ROM (i'm pretty sure it's the right one). My phone seems to be unlocked, but when i tried to do a test call, i got a weird message:
"Phone not registered on network"
WTF ?
I had a hope when i found ARIZA patch, but it failed, it was made for i9300.
I googled it again for a few days, and i found out that it probably is its modem firmware.
I'm not even sure of it and I hesitate flashing it back to 4.1.2.
Any idea of what causes the issue and how to solve it ?
I'm currently using XXALK2 and i'm from France using the Bouygues network, if it helps
Thanks for your help and time, this is my first post here.

So someone can help me ?
Thank you !!
Hi there,
Same problem here and it happened right after MM OTA upgrade.
Does anybody find a solution?
Thanks!!
Anyone??
I've found out that in my case it could be a blacklisted imei number. I've bought about a year ago this smartphone and if I will be able to collect more information I will call the previous owner.
Thanks for your "support" ...

Maybe Your Phone Is Locked To Carrier Network
Which Means U Can only use Simcard From that Carrier
Ask The previous Owner If the is locked or not
Hey Guys , I recently purchased an S6 edge G925F from my local market , in used condition , it came with Android 5.1 Lolipop but when i upgraded it to marshmallow , its GSM capability stopped , which means that it detected my local network but failed to register on my sim network , it would say " could not connect , try later" , G925F roms work completely except sim communication , and when i had this issue , i took it to my seller to repair it , and he refreshed it to lollipop again and said that dont upgrade to marshmallow , because it has GSM bugs etc , and i asked him about what happened and asked that whether it was locked or etc , he answered that my phone got locked (i dont know if its carrier or bootloader or baseband lock) but he said it got locked due to baseband change , My questions are :
Q1. is this a reconditioned phone that was previously some carrier phone that they converted it to G925F ?
Q2. Do locks (network , carrier , baseband , etc) exist for G925F which would produce GSM issues ? like i had ? sim works but fails to register on gsm network
I will be glad if anyone could help me out! (P.S IMEI remained intact , didnt get corrupt, despite no network capability , and i checked , in my country it isnt flagged stolen or etc)

Hello there, this is my first time posting here.
I have a Samsung Galaxy S6 edge (SM-G925I) (TTT Firmware). After updating it to Marshmallow, the phone worked well.
Suddenly, one day, I can't connect to network, can't make calls and can't even connect to 4G/3G/2G.
I am aware of the solutions that have been already posted as:
-Search automatically for network
-Flash Stock ROM Firmware from Sammobile
-Backup/Restore EFS
IMEI and Serial Numbers seem to be the same as on the back of the phone and the phone recognizes the SIM as it shows contacts.
I have already sent it once for repair to some guy, and the phone came with a Movistar ROM 5.1.1 (OJ6), which I didn't like, but surprisingly the Network worked.
I decided to flash my stock firmware, as I didn't want to be stuck in Lollipop, but now the network won't work again.
I would appreciate your help on how to fix this. I have been able to root Marshmallow successfully and I am ready to apply a solution.

I apologize for not mentioning earlier, but it perhaps isn't a hardware issue, as my SIM works on other phones, as other SIMs won't connect in mine.
What is the OS version you are running now?

Currently Android 6.0.1 MM. I flashed 5.1.1 to test before, but no luck.
Would suggest you to switch to MM. And also to go to service center to fix up the device. It might be a hardware issue. Also tell the service center guys you need MM on this and not Lollypop
mine G925I only works on LTE only mode.
cant able to call.
