Note 7 null IMEI, need to write it back. Donation for sure. - Note 7 Questions & Answers

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?

Galax S GT I9000 IMEI problem after flashing

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?

If you have restored the backup properly, just try to factory reset the firmware...
Which method you had used to backup and restore EFS?

Have no Idea what went wrong. I have no backup of any EFS or anything .
I installed emergency firmware upgrade via Kies and now running stock 4.3 Android UBUEMJ4 Modem , build number : MK4 Status : offical.
I don't even know if i can root my device with current stock firmware.

Professional Help and advise needet.

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.

SGH-I747M from bricked and no IMEI/ESN to working!

Hi,
After several days trying to unlock my phone and getting it bricked I finally managed to have it in a working condition and unlocked! I'm not sure if what I did unlocked it, but at least it's rooted and in working conditions.
So I decided to share my story and all the steps that I took to fix it. I would have written just the steps but somebody might find specific parts of the story useful.
Original Equipment and Status:
Phone: Samsung Galaxy S3 SGH-I747M (LTE version)
Carrier: Telcel
Country: Mexico
Original Stock OS: 4.1.1
Last working OS: Cyanogenmod 11 Nightly 20141221
Backstory
I'm having a roadtrip that will take a couple of weeks and I got a TMobile SIM to use during my trip through USA and Canada, however my phone was locked to Telcel.
CM brought me some couple of issues with the modem and network selection and as I live right next to the border and cross it every week or so, I was having a hard time switching between carriers and international roaming so I have to upgrade the modem to the latest one (From I747MUMBLL1 to I747MUMUEND3) and for some time I was able to select network operators but still it was locked.
No USSD / Unlock Code Fail
I found on the web there is a way to unlock SG3 for free through the hidden menu, but it didn't work for me but found out USSD codes no longer work in 4.3 so I restored the stock ROM for 4.1.1 (I have no idea how I managed to do this, but got it downgraded) I was able to get to the hidden menu and followed this instructions but I kept using multiple modem versions that aren't for JB the hidden menu didn't gave the option to generate the nv_date file. I think this was due the use of newer modem versions that didn't have the option to initialize the file.
Next attempt was to purchase SIM unlock codes without success, the providers I attempted were TheUnlockingCompany and CellUnlocker, neither of them were able to get me a code to unlock the phone
Also attempted to modify the NV_DATA file but well, it didn't exist in the /efs folder, there were other files but nothing related nv_data.bin. So I really needed to have that file to unlock it but no success in initializing it.
Third-party local unlock dealer
As all the attempts previously failed I needed to have my phone unlocked and was running out of time. So I took it to a local dealer who has more experience unlocking phones. This part I don't have all the info in whatever he did, all I know is that he was unable to work with CM and attempted to unlock it with a brasilian stock firmware, which got it bricked and it was getting more difficult to unlock it.
AFAIK I did have the old bootloader, but his attempts included upgrading the bootloader which includes KNOX and any attempt to restore old rom versions gave me the error SW REV CHECK FAIL : Fused 1 > Binary 0 therefore it was impossible now to get back to stock 4.1.1 and attempt the older modem versions which at this stage found out could have solved the original unlock issue but .... too late.
His attempt with the brasilian stock ROM got the phone bricked and now instead of trying to unlock it I was trying to revive the phone, all my attempts in bypassing KNOX and downgrading the bootloader failed - also attempted to get back to 4.2 and 4.3 through CM 10.1, 10.2 and stock 4.1.1 but bootloader was too recent which prevented me to use those CM versions.
I was able to get it unbricked using CF-AUTO-ROOT - this is a life saver at least to be able to boot the phone, everytime I get a bricked status just by flashing this allowed to boot.
Phone kinda working: NO IMEI NOR ESN
Finally I decided to restore but directly to 4.3 stock for my original provider Telcel. The phone works now... kinda. It boots and gets signal, but NO DATA. I just found out IMEI/ESN information got lost and I didn't have any backup, yes I know I should have but whatever I was doing at least was not touching that information, but this other guy got it messed up.
One interesting thing is that even though there was no IMEI information, but original SIM card works to send/receive calls and SMS. Data doesn't work, but at least calls and SMS does.
Phone included KNOX and was preventing me to use the previously mentioned tool CF-AUTO-ROOT and found this tutorial: http://forums.androidcentral.com/samsung-safe-knox/352922-sprint-galaxy-s3-possible-knox-fix-cf-autoroot.html - this actually works but didn't give me the option to remove KNOX.
THe problem now is that any attempt to use SuperSU through USB debugging was blocked by KNOX but apps opened directly from the phone weren't, with this I installed CWR right away and TitaniumBackup, this last one allowed me to uninstall any KNOX crap. Rebooted the phone and no more issues whatsover in root usage.
As I only have 1 remaining day to have this phone in working conditions and it's christmas today I went on in trying to rebuild my IMEI.
Rebuild IMEI WITHOUT BACKUP
After lot of research and no friends which the same phone that could give their nv_data files, I found out THIS guide (again USSD codes not working so I used EFS Pro to switch USB modes) and basically this is what I did:
Download EFS Professional - Epic tool to work IMEI/ESN info and switch USB mode between MTP+ADB and DEV+MODEM+ADB
Download QPST version 2.7 build 323 NOTE: USE THIS VERSION, NEWER VERSIONS DO NOT INCLUDE RF NV Item Manager
Follow the instructions in the previously mentioned guide, but the USB you can switch it from EFS Pro under Samsung Tools.
It is really important to notice the IMEI number needs to be entered with the HEX checkbox enabled and in reverse.
You probably could do this straight from EFS Professional -> Qualcomm Tools, but this worked for me.
At the end of the guide there was no confirmation or any message the NV information was written successfully, so I just rebooted my phone and success! IMEI is back!
Just to test I tested my T-Mobile SIM and it works! - I'm not sure if this unlocked the phone or whatever the other guy did, but well the phone now accepts any SIM.
No Data / Stuck on EDGE
Now that the phone has the IMEI number and is unlocked I found out DATA still was not working.
I used the tools ESN, MEID and EUIMID Calculator to generate the rest of the missing information which was ESN and MEID. I entered this information in EFS Pro -> Qualcomm NV Tools, checked the boxes and clicked on write making sure the select box next to it was set to Phone.
Rebooted my phone and yes the information was there, however STILL NO DATA.
I came across this life savior - Load this file with NV Item Reader/Writer Some people on the thread say even their already working LTE data achieved better speeds with this.
Rebooted my phone and wallah! DATA and LTE are back! AND UNLOCKED!
What did I learn from all of this? DAMN KNOX and ALWAYS ALWAYS backup /EFS or whatever IMEI/ESN/MEID info is, even if you plan to use custom roms or not, or unlock the phone.
Link to useful tools and sites
CF-AUTO-ROOT - Fix a failed ROM update attempt in ODIN and/or apply permanent root.
ESN, MEID and EUIMID Calculator - Calculate the MEID and ESN based on IMEI
QPST version 2.7 build 323 - Qualcomm Product Support Tool - Modem and service editor
NV Item Reader/Writer - NV Information backup/restore
this life savior - Restore DATA LTE
SamFirmware - Stock roms
I think i love you ...
