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.

[Q] How do i restore Null imei number

I recently entered the world of rooting and roms etc and yesterday i tried to flash DN3 ROM V5 for my AT&T note 2 GT-N7100.
The flash went smoothly but after the intial set up of the rom i realised I had no mobile service, so I then checked my imei using *#06# and my imei was found to be Null/Null.
I know that this has something to do with the efs folder in my phone but i don't know how to get mobile data back on my phone.
i have an efs back up SAMSUNG-SGH-1317_20141009_213525.tar i just dont know how to restore it.
PLEASE HELP

The correct international rom would be 7105. So you need to return to the stock rom and modem to fix your phone.

The real question is do you have an i317 or a n7100? Those are two different model numbers and you would need the n7105 version of dn3 for i317, The n7100 rom is not compatible and does not have lte support (hence the no baseband problem). Odin back to stock using the correct firmware, then you can re-root and flash stuff. Just be vigilant and make sure you have the correct files for your device before you flash them.

[Q] No IMEI on stock ROM, Network Unlock fail on DN3

Model : SGH-I317M
Network Locked: Rogers
I was running the official Samsung ROM with CF auto root. I made an EFS backup (Using EFS backup Pro) soon after completing the root.
A few days later I tried to flash the modem on my phone to enable AWS bands. After the process my phone got stock on the logo screen.
Then I downloaded the stock ROM + modem from samsmobile and restored it using Odin. The phone boots fine but has a null IMEI and baseband version. I tried restoring EFS using EFS backup pro and the dd command but no luck.
Then I tried the DN3 rom. My phone works perfectly. It boots fine, the network works fine, IMEI is correct!
The problem now is that I cannot unlock my phone. I have tried ordering an unlock code from 2 different websites. Both of them gave the same code. When I insert a different SIM and enter the unlock code I get a message "network unlock unsuccessful". The support team for one of the unlock sites told me enter the code from the UTMS debug menu. The problem is that this menu is not accessible in the DN3 rom. The other company (Koodo) refused to unlock unless I was on the offical ROM.
I tried opening nv_data.bin stored in the EFS parition and it is all 1's. Hence, My suspicion is that DN3 reads the EFS data from a different partition than the offical ROM (dev/block/mmcblk0p3 .
You could help me in 2 ways : Show me how to unlock my phone in DN3 rom. Help me get the offical ROM from samsmobile working.
Thanks in advance to anyone who responds.

So this is a koodo phone, correct? And you had previously unlocked via the service menu?

No Its not a Koodo phone, it is a rogers phone. It has never been unlocked before. Koodo can unlock phones locked to other carriers as well. I took it to them because they were offering free unlock service for new customers. The agent at the kiosk could not find the UTMS menu so he said he could not proceed with the unlock.
I have also tried getting the unlock code by paying a website $20. I tried entering the code but the unlock was unsuccessful. Their support team said that they can only support people using stock ROM and refunded my money.

Note 7 null IMEI, need to write it back. Donation for sure.

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?
