[Q] Mobile network not available & Serial number messed up - Verizon Samsung Galaxy S III

Hi,
My Verizon galaxy S3 has not been able to connect to anything but data (4G LTE only though, not 3G/2G/anything else) recently.
I can remember going through some flashing where I flashed Cyanogenmod (Nightly from around March 28th 2012) and the latest modem.
The issue is that neither calling nor sms works.
I noticed that when I flashed (using heimdall) 4.0.4 back to the S3, the serial number was all 0s (eleven if I remember correctly, so it was 00000000000).
The IMEI is correct, according to the settings.
What should I try to get it working?
Some background info on it: It was purchased at Walmart in mid-March, so it can't be returned to Walmart due to being passed the return window.
Currently I'm running 4.1.2 which I had to flash via Odin (I decided to try Odin since I had access to it for a period of time). It was not possible to update the phone from 4.0.4 to the newest system because of it only downloading about 30 MB (over Wifi, which still works).

http://forum.xda-developers.com/show....php?t=1867442 try this. You can use it to fix your IMIE number and while your at it make sure your ERI number is ok. Then reprovision your sim and you should be fine.

http://forum.xda-developers.com/showthread.php?t=1867442 sorry for posting a bad link. Your imie shouldn't be all zeros. This will fix that. And your Eric should be 5 on Verizon. I don't know about other carriers.

Thanks, I'll give that a try.
And just FYI: The IMEI isn't all zeros, but rather, the serial number is.

Update: Still not working.
I entered the IMEI from behind the battery in and nothing seems to have changed.
One thing I found interesting is that the MEID is not the same as it is when the program says it has changed it.

I dont remember where I found it but look for a program on xda called "Samsung MEID Repair V4.0" or "XDA Samsung Repair Utility (Verizon Galaxy SIII). I believe you can use that program to repair your MEID #.

To be honest, those programs were in the linked page for the first reply you gave me.
They didn't work for changing what the program sees as the MEID.
But the phone reads it in Settings just fine.

I have the common problem, imei number is 004999010640000 / 01 but i have change for the original imei...
helpmeee please :crying:

I'd recommend using Odin/heimdall to restore to stock, then have some Verizon person try to fix it.
That's what I did (be sure to reset flash counter) and they got everything but SMS working, which installing CM fixed.

[Q] cell network loss

Hello!
I have a very strange problem with my Nexus S 9023.
At some moment phone have lost cell network totally. Rebooting device did not help. I tried to reinstall ROM and to change it (same with KRENEL and RADIO).
Sim is ok. No sim works on my phone.
Specs:
Rom - 2.3.4. SuperAOSP ST 8.6
Kernel - Matrix cfs v 6.5
Radio - D1
UPD:
-netmonitor app does not find any signal
-system says "radio version unknown"
-phone was not damaged
-*#*#4634#*#* shows "disconnest GSM: State: DCInActiveState Disconnected with last try at 2:29 fail because No Error". Preferred network type in this window can not be changes from "unknown"
-IMEI is "-"
If anyone have some ideas please help me
Have you flashed a new radio recently? If you have you need to restore the EFS folder using root explorer and reboot. It sounds like you have corrupted the EFS folder somehow if your imei number is not showing.
I found this folder. How should I restore it?

I checked EFS folder with File Expert. And in IMEI folder I have found no files. What should I do now?

Sorry for all of you guys having hard time with this flaw
WOW!
my colleague from service center reports that they have repaired my phone. But it took one week. And samsung techniсians could not propose any solution immediately. They needed some tine to think.
So now i think how to do a full dackup of my phone before next try to receive root and flash it with AOSP

[Q] Reverse Flashed Galaxy S3 from Cricket back to Verizon

I made the mistake of not meeting at the Verizon store and bought a Galaxy S3 off Craigslist. It has a clean esn but it won't read the 4G sim card. I found out it was flashed to Cricket so I used Odin to flash it back to the original rom that came with the version of the phone which changed it to Baseband version: I535VRLEC but this still won't work it still has the same problem reading the Verizon 4G Sim.
I guess my question is... if there is a different rom I should flash it too? Or is it that once it has been flashed from Verizon to Cricket it can't flashed back to be used on Verizon again?
I would just get a new sim card from Verizon, that may resolve your issues. A few questions:
1) Does it still make calls and texts? The main issue is it doesn't connect to LTE? Maybe I'm not understanding your issue entirely.
2) Does the phone have your phone number and matching IMEI (labeled on the retail box) listed in Settings/About Phone?
You could Odin the stock image VRALF2, VRALEC was a pre-release image. Do not accept the OTA then dial *2767*3855# to reprovision the sim card. Maybe see if this resolves your issues.

Well when I brought the phone in the first time to get it activated I was switching from a Droid X so they gave me a new 4G Sim card. But yeah it won't make calls or texts and it won't connect to there 4G data network or pick up the sim.
So are you saying changing it from VRALEC to VRALF2 might fix it?

Oh yeah and I don't have the box it came in but my phone number did show up in the Settings/About Phone
And at the store they told me it was picking up the Verizon network it just wasn't connecting I guess? so it wouldn't get on the internet or make calls or texts

What I was saying is that normally people Odin to VRALF2 or VRALG1 then reprovision their sim card. That code will work on VRALEC but I was just trying to put you on a common starting point since we here don't really use the VRALEC stock tar in Odin. Primarily what you'll find in the stickies are VRALF2 and newer images. VRALF2 was the "store bought" earliest software version of the Verizon GSIII from the summer. Its worth a try but consider the following first.
Since you said it doesn't call/text then I think you lost your IMEI. Could you check for me under Settings/About Phone? It should be 15 random numerical digits if I'm not mistaken. If its not 15 digits, it will be 0 or several 0's. Don't post the exact number if it is 15 digits, but tell me what you see.

No I didn't lose the IMEI it's still there, all 15 digits.
So is it possible to flash a Galaxy S3 from Verizon to Cricket. Then back to Verizon? Is it just a matter of changing to the right software?

Honestly I know nothing about flashing to another carrier. It's not something that I have a reason to research so I'm not knowledgeable in that area. My suggestion still is to run that reprovision code since you've already Odin flashed to VRALEC.
EDIT: To clarify, my suggestion is Odin VRALF2 then run the dialer code.
Just as a precaution, you should write down your IMEI, ERI, and maybe even your MIN and PRL version and store them somewhere on your computer. Since you don't actually have the retail box, this should be kept safe if we can't get this current situation straightened out. My reasoning is if you do somehow lose these before you're 100% fixed, having them written down may help you if you need to use one of the IMEI or ERI tools in the dev section.

Ahh, great! When you do just make sure to root, unlock your bootloader, make a nandroid backup in CWM or TWRP recovery, then use the "Comprehensive IMEI /EFS Backup" thread to properly backup your IMEI.
I encourage you to flash roms until you find something you like. I'll suggest that you stay with touchwiz roms then see whether sticking with Samsung's software in its various forms is good enough for you. If not, there's plenty of AOSP to go around!
So you just followed step 5 on the link above and it worked? (flashing with 4.0.4 ROM)
I'm going through a similar issue and been having a hell of a time getting mine to work. Mine was flashed to work on nTelos which is a CDMA provider in my area. I have flashed to just about everything possible (except 4.0.4) and haven't had any luck.
I went to the Verizon store and they tried to activate the phone but they couldn't but game me a sim to use and told me to call back if and when I could get it flashed back.
I tried at one point to take a working sim from another phone but it will not activate..... will not make calls, will not get data etc etc. when I dial 611 it still goes to ntelos.
Someone suggested putting Phone info on and setting the Phone to RUIM but I could not find that setting in Phone Info (even on the correct phone info, after time I found out the original phone info was pulled from the play store and I had to manually download it.
Anyway with the SIM I have and following section 5 as suggested mine does not give the option to accept or deny the OTA so I can try to enter the re-provision code. Should I get hold of the known working SIM to attempt this?
THANK YOU SO MUCH!!
The key to this however is to have a working SIM (the only one in our workplace was from an iPhone 5), I fashioned a nano SIM to mini SIM adapter and got the info on to the phone then my phone could finally be activated however the nano SIM I used got tied to my phone and couldn't be put back to the iPhone 5 it came from lmao... so I had to run to the Verizon store to get my co-workers phone re-activated.
But going down to the 4.0.4 and VRLEC modem then inserting the active sim, reprovision once it activates (it didnt give me the option to not allow it to do anything), then insert the mini sim, call Verizon they got it activated, I just now updated back to 4.1.1 (need to get 4.1.2) and everything is working wonderfully!!
All of this info is extremely refreshing to hear since I have the same problem with one exception. My s3 has a bad charger port. Sent it in for warranty repair and Samsung said it was moisture damaged and corroded and is not covered under warranty (lies). But that is beside the point and another subject.
My question is, can all of this stuff be done through the sd card and not through the USB? I know it is a long shot but any help would be greatly appreciated.
Thanks!
I know this thread is a little old but I just wanted to say thanks, the exact same thing happened to me (phone was previously flashed to cricket but i was unaware until AFTER purchasing and trying to activate)
ODIN Flashing the OMBINATION_I535VRALG1_I535VZWALG1_743127_REV09_user_low_ship.tar.zip package then reprovisioning with the *2767*3855# worked like a charm, I was sweating for a while as the deal was from craigslist
So far as i can tell to do this you NEED to use the VRAL as I tried a few other (newer) stock files and this was the only one that worked
THANKS AGAIN!

No GSM/Edge Connectivity .

We had a few hours network outage due to security reasons. But my G3 didnt recover when the outage was over and is still stuck at "no Service" even after several reboots, clean flash of cloudy and restoration to stock using nandroid. It was working just fine a night before. I have tried restoring Stock from nandroid but still no luck. I have tried different SIM cards too but still no connectivity.
*#06# shows proper IMEI number.
Baseband was shown as Unknown, So I flashed one from xda threads for D850 V10D. Now my Baseband is known. But no luck.
Wifi works fine.
Bluetooth works fine.
Sim Toolkit works fine
SIM contacts are visible
AAT tests USIM1 Passes
I am back to Stock using TOT method.
I even had a bit of luck and caught some signals last night but they came and Whooosh gone again never to return.
It is to be known that I am in Pakistan and D850 is ATT US. Do I need to take care of any unlocking to make it work here that the shopkeeper may already have done before selling it to me ? Because it worked fine before.
Edit::
I checked for unlock code. my phone says "Phone is not personalized". So i guess I am not operator locked.
Previously I had posted this in "G3 troubleshooting" forum assuming it to be cloudy ROM related but I think its much more serious than that. So posting it here in D850 Forum.

Network not available at recently 4.4.2 flashed N8000

Hi guys. I'm posting here in a desperate attempt to solve my problem.
A year ago I purchased an used N8000 with Omega 4.1.2 ROM installed, and worked very good. But a couple of days ago, I flashed my tablet to get the 4.4.2 update, because I need some apps not compatible on old versions.
Everything is ok except for the fact that my sim card is not recognized anymore, if I select the operator manually, I get a "network not available" error.
I made a lot of research, with no results so far to fix the problem. The only thing I learned is that I think it has something to do with the baseband version. Currently I have the N8000XXUDND2 version, the IMEI is ok.
I live in Paraguay, the 3G band of my operator is on 850MHz.
If there's no solution, can I just downgrade to the omega rom by flashing as usual? Or the process is different?
Thanks in advance

I don't even know how can I check the original imei of my device, since I forgot to write it down. On phones they are usually printed behind the battery, but this doesn't have a detachable battery.
If your IMEI is wrong then restore your backed up EFS folder .

It's written at the bottom back of the tab & on the box seal as well. Or dial *#06#. I tired hard reset & stock rom still imei error
I checked and indeed there's the original imei written at the back of the tab, and it's not the same number as of dialing *#06#. Don't know how to restore though since I didn't back up any efs folder.
You can do a search on XDA there are a number of posts regarding users that failed to backup EFS and null IMEI .
I have the same error, after root, imei and baseband are gone.
don't have efs backup

S7-G930F/FD Issue

Hello everybody,
Yesterday I went to local phone reseller and bought used SM-G930FD for a good price. It's condition is flawless, came with tempered glass aplied also stickers on camera and heart monitor. Tested before purchasing and everything was working. When I came home only then I noticed that it had SuperSU installed and at that moment ran android 6.0 with 2016 security patch. After some reading I loaded the firmware from 2nd post via odin selecting three options :https://forum.xda-developers.com/galaxy-s7/how-to/official-stock-firmware-update-odin-t3369431
1)Auto reboot
2)Re-partition
3)F-reset time
Note that the phone had no "secure startup" option so I didn't need to set pin. After it booted up the phone no longer detected my sim, which prior worked with android 6.0 also download mode says it's SM-G930F, but software reports it being SM-G930FD and I have option to select 2 sims in menu?
Also yes, the knox is tripped, which I didn't notice before purchase, I have few options in mind, which one would you do if you were in my case?
1) Return the phone with reason that there's no signal and choose another SM-G930F which 95 percent will have knox tripped aswell, as they're all used.
2) Solve the no signal issue myself and continue using the phone with knox tripped as the condition of phone is 10/10 (Is my phone more prone to viruses and malware without knox? I came from iphone, but prior used android and take good care of my phone)
3) Ask for refund
Note 2: The seller also gave me a 6 month warranty which might work/might not depends if the seller knows about knox?
Thank you.

Im downloading SEB(Baltic firmware), that should fix the sim issue. Can't tell you why I loaded netherland firmware
Imei should be okay, incase not, how do I check?
Could you possibly check how fast does this file is being downloaded for you? For me 6-10 hours.

Had the same exact issue. I've noticed the presence of SuperSU and I know what does it mean on a Samsung device. Checked both IMEI (*#06* and on the back of the device) and turns out it was changed or swapped to a different one... and just like you, my phone was running Marshmallow with Security patch from 08-2016. I though there was no problem updating it to 7.0 but after phone booted up i've noticed it lost network connectivity (kept on "Emergency calls only"). Started to research and found out that there is a box which is called "Z3X box or Samsung PRO" which modifies the IMEI and then patches the phone in certain way it becomes dual sim even thought is not really (you will see a second IMEI with only zeros and phone becomes G9XXFD but it's really a F only). The solution, at least for me, was to get someone to patch the modem once again using the box i've mentioned and I got signal back. Only downside is you won't be able to factory reset nor update in any way, flash another ROM or remove root because you will lose the patch again and lose signal. Hope I was clear.

You should download the latest firmware from sammobile
To check IMEI *#06#
If it is like 000.. or "null" then it is IMEI problem and then You need a z3x box to properly fix it (or give it to mobile repair shop)
If it is okay , then no problem . . . . .

Yes , z3x box is the best toolbox for changing or repairing IMEI or for doing other useful stuffs
but if IMEI is okay then there is a option to repair network
it directly repairs the efs folder and get the network active again
In my case , I am using S3 i9300 and whenever i flash stock firmware with odin then the network issue always SUCKS even if IMEI is okay !!!!!!!!
There's 2 Imeis, one with numbers, one with 0000

Yes, he could patch the modem using Z3X but like I said he couldn't be able to update the phone nor flash custom ROM's. That's the catch with the S7

Check if the one from *#06# is different from the one on the back of your phone, look carefully because sometimes it can be 90-95% similar

I returned the phone and instead he gave me a golden one. This unit runs 6.0.1 with 2016 March 01 security patch. Only one imei and know is not triggered. The drawbacks are some dents on metal frame, slight burn in of Facebook, didn't came with tempered glass and no more stickers on camera or heart monitor. I plan to flash the baltic firmware via odin, is there any chance it'll trigger knox? I'll do repartition as well

Flashing stock with ODIN will not trip KNOX
Only flashing custom trips KNOX
