This is my Mom's phone. This began randomly two days ago. IMEI shows up as garbled symbols. Phone number shows as "unknown".
she apparently brought it to the at&t store before she had me look at it -____-
they replaced her sim and also did a factory reset. Same issue.
Is it a hardware problem or is there something I can do software-wise?
I am pretty familiar with android since I've been screwing around with my cappy for almost 2 years now.
The only reason i can think of may be that someone messed up the efs files which is your IMEI...maybe trying to unlock it.....best explanation i have

Should I poke around with adb to see if there are any backups of the efs file?
BTW kies shows this as "unregistered device"
imei garbled
I have the same problem. I am looking for a solution but can not find

My phone has unknown IMEI and baseband. Cannot recognize SIM card. No service. The SIM card works fine in the other phone.
Okay Developers & Non-Developers, Simple Explanation to my Problem.
1)Sprint manufactures a phone with Contract lasting for 1 year. This is a CDMA phone. John buys this phone in USA.
2)After contract is over, John's Friend - Jill Takes his phone to India, Goes to Reliance CDMA Gallery and Unlocks this phone, She gets a New phone Number.
3)Now Jill is happily using the phone. Note that, She has RELIANCE network and her Phone number is "INSERTED" in the phone as this phone doesn't have a SIM Card Slot.
4)Jill deciedes to sell this phone to me. She ERASES everything including her number which was in the phone and sells it to me.
5)I already have a CDMA Reliance Phone. All i have to do is go to Reliance CDMA Gallery and "INSERT" my number in this phone.
6)When I go there, Reliance girl says "The person who used this phone before, we need her number in this". I say"But she deleted this number". She says"Get her number first or the phone is useless".
7)She does not answer her call.
8)My question- Is there anyway i can I) INSERT my Number into the phone?
(II)o something to the hardware so that I can Directly insert my CDMA Reliance SIM?
Awaiting Reply. Panic-Stricken! :crying:
You'd have to flash it yourself through CDMA WS, DFS, or qpst. Google them, but I think Dfs and qpst have free versions.. Make a backup of all the settings first through whichever flashing to you use though!

Alright, so using DFS or QPST i have to FLASH another ROM in my phone? Or REPAIR stuff within it?
First off, I'm not a professional or very good at this
so be careful, in fact, if I were you, I'd have someone else flash the phone for me. Anyways, you're not flashing a ROM, you're flashing your number and and all the other stuff that goes with it to the phone. I'd use a donor cheap junk phone that's already flashed to your line, and copy the settings from there. Then experiment with the settings to get data/MMS working

I have a Cobalt SP300 I bought on eBay. It has a MT6575 SoC that has a 3G radio integrated according to the manufacturer. I know other phones like the Zopo 100 with this same chip can access 3G bands of 850/1900 mhz. I looked up the IMEI number on some websites and it shows it to be a basic flip phone from early 2005. I currently have a feature phone unlimited data plan on my account, that worked fine on 3G on my old phone, but I can only get EDGE on this phone. When I go on the AT&T website and look at my account, it shows the device as unknown. Could it be since the device is unknown they restrict the data to EDGE only?
I happen to have an old 3G flip phone. I can be sure it will never be used again since the pins on the SIM slot broke. If I were to change the IMEI number to that phone's IMEI number, is it possible it would allow 3G?
You can't change your phones imie number its illegal and would get you into serious trouble

I have one which had two legal printed imeis which worked until I pressed factory reset which wiped them. How can I put them back.
There is nothing illegal in this as I have proof they are the phones numbers

You will find no info here on editing the imei as this is illegal and not to be talked about here.

I've searched but couldn't locate info. Can you help?
Can my blocked imei, be used on an alternate Australian provider, or is the block national for all carriers? eg: 123456789123456/2, slash 2 is appended on the end of my imei.
Bought a phone from a homeless person, to help them out, and it was a really a good idea to help out, but now the imei is blocked on my service provider, despite being ok when I tried my sim. I have the same service provider as was on the phone previously and cannot make calls. I get the message that this number is blocked on the Optus network.
I threw the original sim away and can't even locate the owner through the carrier. They don't give out info. So no chance of returning it to the original owner for a reward to recoup my losses.
Samsung Galaxy Note 4 Edge N915G. Phone now has root access..... Tried to manually update the IMEI, back to the original without the /2 appended to the end, but unable to get any of the programs, or terminal emulator codes to work with this latest model. Seems that it's a bit of a problem.
Don't have money to spare (gave it to the homeless), to try out an alternate provider and find it's not working, so your knowledge and help is appreciated.
Back to my original question, can anyone help?

I think, if an IMEI number is blocked, it is blocked throughout the country in all network providers.
To be on the safer side, just change the IMEI number of the phone.
Though this is illegal, you can do it the right way by using the IMEI number of any of your old phone.

Hello,
A friend of mine has a new S6 which is unlocked to work with any network/sim. The phone was working perfectly for a few months.
Now for some reason, it gives the message that no sim detected. Signal bars show up. But no connectivity.
The option in settings Select Network Operator is gone, and no longer there.
I have tried re-flashing stock 5.1.1 ROM and still the same problem. Tried flashing previous 2 modems and got the same error, so flashed back to current one.
Current Baseband: G920FXXU3QOKN
Kernel Version: 3.10.61-5896496 [email protected]#1
Another thing to note is that the phone shows signal bars perfectly, even though there is the no sim message. Also, on removing and re-inserting the sim, it reads the sim and asks to reboot, after which it comes to the same situation.
Any help would be appreciated.
Thanks,
I have same issue, and would gladly fix it. :/

IMEI was reset to 350000000006, then some Russian guy fixed it with Z3X box, SIM was able to register, but reception was awfull (lots of missed incoming calls, etc.). then I flashed some more fw and modem to check wheter it would fix dropping signal issues, and then it started not to recognize SIM.
So to sumarize, IMEI (with my EFS, not @tazaga one) is fine in the IMEI info, in SIM info everything is unknown, and mobile networks menu is missing from settings.
I changed SIM for a new one, just to be sure, and is detected only when inserted/removed, then phone wants to restart to enable mobile networks, but after restart, nothing changes.
Serial number was changed, but I corrected it in a file in EFS folder.

Ya by the sounds of it something is still funky in your efs folder
As far as my problem is concerned, the IMEI and the SERIAL number both match the inside and outside. So its not that.
Any other suggestions as to what it could be? Or how to fix?
Flash stock with smart switch but before that make efs backup ( in case things goes down )
Already tried smart switch and also Odin to flash stock. Neither worked.
Would flashing an EFS backup from another phone with the exact same model work?

well I tried to flash @tazaga efs, IMEI gets unknown right after that, but managed to boot up without custom kernel after Smart Switch initialization.
Beside that nothing changed, still no SIM and no mobile networks menu, and sadly couple hours later, phone went to a boot loop.
I took it to some 3dr party repair shop, without restoring original efs and bootable fw/kernel, they said they cannot repair it, but will give phone to some "software specialist" who may be (I seriously doubt it, according to my prevoius experience with 3rd party sw specialists (last time it took me half a day to reach the state phone was in when I deliverd it to them)) able to fix it with a 50-50% chance of fixing it.

Dude it it can be fixed its just you need octoplus box or z3x box

I understand that, but I kinda doubt that no SIM issue is somehow tied to IMEI
Because with my efs backup (which was made after Z3X repair) IMEI is fine, but still no SIM.
I was kinda hoping that it could be something else in the EFS folder that made SIM undetectable, but even with your efs backup (thank you once again for it) SIM is not detected, so I guess that no SIM issue is tied to something else that is corrupted, or accidentally switched off.
I just dont know what could it be, because I was messing with service mode and codes unknown to me to try fix poor reception, so god knows what I did to put the phone in state in which is now.
Perhaps I am just trying to provide every information possible, and exchange it with others who have same issue, or more experience than me, so we can together figure out what has caused this and how to fix it, and help others who will have same issue in the future (and obviously I am not the only one with such issue).
And as I pointed out 3rd party repair shops didnt proove quite usefull (perhaps their services are just flashing/rooting/unlocking, but I can do that by myself without paying someone else to do it)
We will see next week, what will guys from repair shop say, but I am not very optimistic about that.
If nothing else I can still give some money to that Russian guy with Z3X, who fixed IMEI in the first place, I guess he won`t mind
And sorry for the OT.
This problem still going on with exact answer..
I also have same issue on customer's phone.
I've tried backup cert and efs then repair efs (on octoplus).
after repairing efs, it changed IMEI to 3500...006 but still no sim card.
Seems like I can't fix even with Octoplus.
Hopefully someone finds way to fix this asap ;(
So apparently EFS and stock firmware has been ruled out. I already tried different modems using Odin.
Anyone have any other ideas? I mean other than the Sim Not Found thing, I can't even see the network selection option in settings, and using *#*#4636#*#* only gives an error that not registered on network.
well @ariza27 made similar fix for S3...
http://forum.xda-developers.com/galaxy-s3/help/solved-siii-network-problem-update-sn-t1918601
I guess there is nothing to do but wait for developers to create something for S6.
If I am understanding that problem correctly, the SIM/Network problem in the S3 came from the SN or IMEI changing due to upgrade or flashing.
This phone has the same SN/IMEI inside and outside. And its not just refusing to register the SIM, the network options have disappeared as well. I had hoped flashing stock would help, but no cigar.
One thing though, would completely erasing the data partition, and wiping the entire firmware, and then installing stock or even another ROM help? Because even when flashing through odin, it preserved the data for some reason.
Can someone send me their EFS backup for G920F on v.5.1.1 Stock with baseband/modem G920FXXU3QOKN?
I don;t know if those things affect EFS or not, just want to be on the safe side. I want to try comparing the backup from my phone and one other and then try and restore using the 2nd one.
As far as the IMEI and SN changing goes, I am looking into how to prevent that in the first place on in the even that it happens to restore it.
Any help is appreciated.
Bump! Anyone?
Your imei number has been blocked/blacklisted because of a reason like lost or stolen phone, reported by previous owner, the only way to fix it is to replace the motherboard of the same model from a supplier on aliexpress website, there price is about $350.00 Australian dollars thats including EMS express postage,you get it around 4 or 5 working days, dont waste your money or time on anything else it won't work, I had same problem, now after new motherboard my galaxy s6 edge is working fine, expensive though.
Any luck with this issue?

The phone was purchased new. And Already spoken with both Samsung and Vodaphone regarding this and they say the IMEI and the phone are clear. The phone is in another country from that of purchase, but since there is no country lock or phone lock, this is not the problem.
And no such luck yet.
