I have galaxy s docomo sc-02b was working fine until I flash it with GALAXY S - I9000XXJVS - FIRMWARE 2.3.5
after that phone's IMEI disappeared.
I tried
Generate Unlock Windows
MobileTechVideos_Galaxy_S_IMEI
nothing works.
even I flash back to previous firmware it stucks.
please help
No, there isn't. The imei is encrypted data in your efs folders of your phone. Once it is tampered with them you're very likely sol. As any kind of imei altering discussion on xda is illegal you'll probably get no help either. Which is something I actually went through myself when I flashed a bad rom on my nexus s (R.I.P).
-We do what we must because we can; for the good of all of us, except the ones who are dead-
will flashing it back to its original firmware would make any difference or it's blocked forever?

Hi all,
I have an I927 with a standard IMEI (0049...) after unlocking it with Z3X box.
The phone is an AT&T I927 and before unlocking I flashed the rogers kernel and then rooted it (as per http://forum.xda-developers.com/showthread.php?t=1378082) all this worked fine.
I have a back-up of nv_data.bin before unlocking and I have tried placing it back but this phone has some sort of weird extra checks which doesn't seem to exists in other android phones such as I9100 and the IMEI stays broken.
Anybody out there with the same problem and some ideas on about how to repair it?
I'm currently living in Peru and I was using the phone with Claro and it worked for like 2 months but since a few days it seems they blocked the IMEI (can't logon onto the network anymore, and sim works fine in other phone).
Also I've been searching for original AT&T kernel to put that back and then try to put nv_data.bin back to see if that makes any difference (shouldn't but I'm kinda desperate here)
thanks

Hello all
My ATT glider recently experiences frozen screen and Ive heard of reflashing the stock ICS rom may figure this out
The phone was bought from ebay and is now being unlocked on 4.0.4(not sure if its legit unlocked)
But I learnt flashing rom may possibly lead to re-locked of the phone
And found solutions about backing up the EFS files could retrive IMEI and unlocked status (correct me if im wrong)
Not sure which solution to go with
1. spocky12's GalaxSim Unlock here
2. EFS Tool (http://forum.xda-developers.com/showthread.php?t=2019540)
3. EFS Pro here
please advice

firstly, what are the first few numbers of the imei in about phone ?
Are they the same as the imei sticker inside the battery cover ? .. That is step 1.
If yes, then backup your EFS not using a tool but with ADB. There's a tutorial you can find that will explain how, its the most certain way to back it up.
then, once you have it saved and emailed and archived to your gmail account, google drive drop box.. whatever ... and clearly renamed to WORKING-EFS-GLIDE-(date).zip THEN start flashing.

I'm running the PA rom and GalaxSim 2.0.2 worked for me. It's not in the market anymore, but the apk I found worked when I paid for the unlock (after a reboot, that is). I've only had to use it once, but it seems like it'll work as many times as you need it without having to pay again.
There is a thread discussing this at length - http://forum.xda-developers.com/showthread.php?t=2019540
Hello to everybody,
First of all sorry for my english.
So about what is the tread
There is arround 10 bricked phones in Bulgarian Android Forum.Becouse we cant find where is the problem I decide to ask here.
Problem: After flashing stock test 4.3 and downgrade after back to 4.1.2 the result is --IMEI 0049 and Permanent Test Mode.
what we know until now:
Phones bought from shops for phones reported they downgrade back without issues
Phones bought from mobile operators -bricked IMEI
Flashing again 4.3 after brick do not restore IMEI
P.s
Sorry if the tread is on wrong place and 10x for your opinions about problem
Find someone knows English better to translate it for you
Impact on device/How I know I have corrupted EFS
When there is EFS partition is corrupted, device loses IMEI and due to this device can't gets connected to network. Baseband info also sometimes shows unknown.
-Check your IMEI in setting / by dialling *#06# if it is null OR if it starts with 0049** then IMEI is generic and corrupted. In Normal case IMEI which you can see in device setting or dialing *#06# is exactly same you can see on bill/box/sticker under battery compartment
-If you are unable to connect to network in spite of correct IMEI, chance are
A. Your device is Locked to specific Network OR
B. Your device is banned due to tempered IMEI
-If your AP,CP,CSC all are correct and even you are getting error (unknown CSC XXX) on kies update, it may be due to corrupt Product code in EFS. Read This for detail.

If you dont have efs backup then you probably need the z3x box to make repair for your imei and change it to the original one didnt test the ariza patch on this kind of problem but why not give it a shot

Note 2 GT-N7100 - No service
I will borrow this thread as I have the same issue.
Hello, friends.
I have a interesting problem and would like to ask you experts for help. I know this is a thread for GS3, but the problem is similar for my Note 2.
BACKGROUND:
I have Galaxy Note 2 N7100 which was working fine for a year and then suddenly died of SDS. I returned it to official service for repair where they said they replaced the chip (i am guessing they replaced the whole motherboard). When I got it back everything was working fine except when I inserted my SIM card phone had no service.
I went back to repair service and after few days they said they don't know what is the problem and how to solve it and I can get another N7100 in around two weeks. At that time I was developing Android App, so I managed to get the broken Note 2 back for developing. Eventually I got a new, working N7105 and they also let me keep the old, broken one.
I would like to get the broken Note 2 working again, as I believe it could be fixed, or at least I could try.
PROBLEM:
After motherboard replacement (because SDS), phone has No service. Phone appears (*#06#) to have a valid IMEI number (3536270500*****) BUT it is a bit different than on the sticker under battery (last 6 numbers are different, * chars). Serial number is also different.
I am guessing it changed with motherboard replacement? Could this be the problem?
Sometimes it shows that the phone has signal and has connected the right service provider, but it is just for a short while. When there is no SIM card, phone has No SIM icon, but shows signal bar, which appears to be working for Emergency calls only.
Phone was never rooted or flashed before SDS happened, so I don't have original EFS backup before motherboard replacement. First thing I did now, was Root, EFS backup and ROM(4.1.2) backup.
PHONE INFO:
Model: Samsung Galaxy Note 2, GT-N7100
Device Type: t03g
Product name: t03gxx
Phone is unlocked and unbranded (at least it was before SDS).
Currently it has [ROM][4.3]N7100XXUEMK9 DeOdexed & Zipaligned installed.
PDA version: N7100XXUEMK9
Baseband version: N7100XXUEMJ9
Bootloader version: N7100XXDME6
CSC version: N/A, but under CSC info it says Sales code: XTC - which I believe is Philippines. I am from Slovenia, Europe.
IMEI: 3536270500xxxxx (www.imei.info says it is valid)
IMEI on the sticker: 3536270501xxxxx has last 6 digits different
S/N: R31C80xxxxx
S/N on sticker: R31C90xxxxx
WHAT I ALREADY DID:
Phone had Stock 4.1.2 ROM installed.
I rooted the phone, did EFS Backup, entire ROM backup with cwm ROM Manager.
Excluded SIM card issue. My SIM card is working in other phones. I also tried other SIM cards in my N7100 and they all have no service.
Tried flashing different modems on 4.1.2 Stock ROM.
Tried Ariza Patch.
I flashed it to [ROM][4.3]N7100XXUEML6 PreRooted, DeOdexed, Zipaligned & KNOX Free
I flashed it to [ROM][4.3]N7100XXUEMK9 DeOdexed & Zipaligned - Current ROM. Because UEMK9 is installed on my working N7105
Tried flashing different modems on 4.3 ROM.
Tried deleting EFS folder to rebuild itself with generic IMEI (0049..). In that case it shows as connected to network every 10 seconds for about 5 seconds and then disconnects. Then copying old nv_data.bin to new EFS. It didn't work so I restored EFS.
I tried other stuff and did a lot of search but I am also quite new to all this rooting and flashing stuff. So if you guys have any suggestions that I could try (even if I already did it) please, do suggest and I will try. If you need any additional info, please ask and I will gladly post it.
I attached some pictures with SIM card inserted and without SIM card.
Hello dear XDA users!
First of all I would like to give offer to one that will solve my problem, I will send him 30 EUR directly to his PayPal account.
I am Note 7 Lover as I am collector of these phones.
I have many succesful Note 7 phones recovered from death updates which were fully discharged.
But I did great mistake which I can´t live with.
I had one Note 7 , fully functioning with all connectivities. I managed to install HydraRom and Hydrakernel there on my own as I did it many times before. I am an idiot I didn´t make backup of the system and mainy EFS in working state.
I broke display a little on my primary Note 7 so I needed to recover my TWRP backup on another phone but I accidentally checked restore also EFS partion from my previous phone.
So the phone just turned on and No service, Baseband unknown. My great mistake.
Tried lots of original ROM restore, reflashing HydraRom or radios/kernels, nothing works.
I read a lot about what i did, I have no backup of EFS partion from the one that has problem. I have only Samsung Box with only IMEI written on it, back cover is changed so there is no IMEI or S/N.
I googled a lot, tried all the programs (Z3x, Chimera, Octopus) but none of them has capability to write IMEI directly to the this N930F phone.
I finally found a software called SAMFIX V1.3 and after clicking Baseband in the HydraRom phone menu is visible
The phone is able to look for carriers (but only one) but had NULL IMEI.
Wifi and Bluetooth works well, but there is no IMEI when i dial *#06# and imei is 0000000000. And Bonus is that the phone acts as Dual SIM, through it is only N930F single SIM. So the phone menu in HydraRom after dialing says 0000 for both IMEIs.
I tried to write IMEI with software IMEI changer via xposed, but it "writes" it only for the system instance.
Phone is still unable to find my carrier of connect to one.
When i tried to see device info with all softwares it says:
PDA Version: N930FXXU2BPJ8
Baseband Version: N930FXXU2BPI5
CSC Version: N930FOXM2BPI5
Please help me to restore EFS somehow, or at least to succesfully write IMEI and S/N (which i don´t really have) to phone and can connect to my network as before my idiosm I did with restoring ROM from "same" but different device.
Who will help me will get 30EUR from me (student) on his PayPal.
Did you tried stock firmware? If not flash N930FXXU3BPL2, and do wipe. https://forum.xda-developers.com/note-7/help/n930fxxu3bpl2-t3520988/page2
Hello!
I tried flashing oficial firmware, didn´t solve my problem, or something called COMBINATION Factory binary but this failed.
Radio and baseband is all OK, I have two other phones exactly with this firmwares and versions and they work all OK.
Problem is with EFS and CERT, before wrongly restoring this partion with TWRP backup from another NOTE 7 SM-N930F the phone worked all OK.
I managed to do with many softwares to write IMEI and S/N and it succeeded!
It is written in CERT file and not only with some IMEI changer for system run instance. It is readable via ADB.
Phone can unlock the SIM card but is unable to load carriers.
I read a lot of this problem and I compared CERT file of a backuped one and CERT on the restored one after my IMEI repair.
The CERT on the recovered one has it´s own IMEI now but has same ImeiSign,PubKey,PubKeySign as the backuped one from what I made restoration with TWRP.
So these codes are OK for the IMEI and S/N on the working one but they are inconert for the not working one because of encrypting.
I tried to flash CERT from the working one to bricked one but this does not work because of some CPID encrypting or so.
Have you please any solution to
1. Fully restore working EFS on the phone to work as before?
2. Try to make calculation for the right ImeiSign,PubKey,PubKeySign for that IMEI?
