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.

No that's not possible, Samsung live demo units have missing GSM parts , you can only use them limited with WiFi
That´s not 100% true, you just need the right tools for it, I have assembled the missing GSM parts in an Note 4 Edge 3 weeks ago and it´ss working great.
In addition you need an IMEI (best is when not used in your country, so check syourself an abroad IMEI) and then flash the unit with IMEI and actual SW.
Can u check an LDU S6 Edge for me?

Not trying to be a smartass, but his question was can a activate the GSM part by flashing. The answer is no. Sure you can change the whole mainboard too and have a working phone. Maybe even solder the right missing parts if you have the specialized equipment needed for this. But this is not for the average soul
Buying a Board, checking IMEI and getting the image for the model is much more difficult. But do what ever you want.
your "smartass"
Need some help please
I have a Live demo unit as well, but did not know that the GSM parts were missing, so I rooted it :S Now i cannot seem to get it to boot or flash another firmware on it just to get it up and running again.
Anyway I can get it running again? I just need to be able to undo the root i think, but trying to flash a stock ROM throws the following error:
<ID:0/006> NAND Write Start!!
<ID:0/006> FAIL!
Would really appreciate if you could help.
Thanks!
I've been trying to push a new rom to one of these demo units I've bought off ebay for 2 hours
.
So far
download mode isn't recognised by odin.....WTF?
but the phone is recognised like normal via USB
I put it in developer mode and the stock boot loader allows adb sideload.
but CF-Auto-Root-zeroflte-zerofltedv-smg920i.tar.md5
and twrp-2.8.6.0-zeroflte.img.tar
and a "stock" rom I found
all give wrong footer signature verification failed
There is an update from external storage that doesn't exist!
and update from cache
I don't know how to use that.
So how the help did you root it in the first place?
Without Odin or adb and without root. How do you apply an update? You can't change the recovery....

Hey shadowcliffs
Can You please share those 3 files that you downloaded to recover you SM-G925X LDU?
i flashed lt with the 925f version which messed it up when odin reached flashing modem.img thats when it failed. (probably since it dosent have a modem )
Once i messed up flashing it with a firmware that had modem.img any other firmware couldnt bring it back. (even removed sboot.bin modem.bin cm.bin) out of 925f rom
My original firmware that was on the device is bloated with stuff, but i rather have a working wifialphabet then a bricked device.
So can you please share those files, for i tried everything.
Thank You
You don't need those 3 files, and the AP file (which is 6.6 GB) wont flash anyway. You can just try to flash this recovery for 925x to see if it brings your phone back.

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 !

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
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.
Proud owner of G925I running Alexis Rom. Change the sim card...its metal part has damaged and you will be good to go.

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.
