I have a SM-G920F and one day the imei went 3500000000006. This made the phone go "No Network" and no sim would work in it. I then proceeded to repair (not change) the imei to its original imei as stamped on the back with numerous files and fixes to the point I am now abit lost.
The phone is now on Factory Binary bband vers G920FXXU6ERC1 BUILD NUMBER LRX22.FA50_G920FXXU6ARC1 and after reseting the EFS the imei is back to 350000000000006 / 02.
I have tried to "repair" the imei to back to its original imei but which I could do before but now I just get:-
Waiting ADB device... OK

The imei above is not mine that just appears when I try to repair the phone but *#06# says 350000000000005 / 02 and no S/N. The only FW the phone will flash with is
G920FXXU6ERF5_G920FDBT6ERF1_G920FXXU6ERF6_HOME.tar (BTU) using samfirm and the factory binary thats on it at the mo , all the rest fail in Odin.
Is the phone bricked or is it sw repairable ?. If it is repairable could someone please point me to the correct files that I would need and which program/s do I use and the order I flash the phone with the files ?. Any help or guidance would be greatly appreciated. I have spent the best part of a week reading up and flashing the phone but I'm now at the point were I honestly don't know which files , programs to use and in which order. Any help files or links, guides would be greatly appreciated.
P.S. just to make it clear the phone is not blocked it seems it just got corrupted somewere along the line and I am trying to restore the imei back to it's original imei not change it in any way shape or form and hopefully fix the "No Network" which is stopping any sim from been used.

This is what helped me. I couldnt even turn my phone on and computer didnt recognize it.
Thanks for that , I did try it but still the same. I think mines a deeper problem , something to do with a corrupt EFS or NV_DATA.bin. which files and how you repair it I think is my problem

I've soft bricked my g930f but managed to get it going again and it's rooted. However, along the way I have managed to lose my IMEI and some other info. I am currently downloading what I believe to be the original country firmware (trinidad / tobago) and will try flashing that when I have it. I don't know if this will restore the following information that is missing, as well as (I hope) enable me to once more connect with my GSM provider. If anyone knows whether this will work I would value the advice.
Using PhoneInfo, here is a list of the missing information on my g930f:
Country of Origin (this used to be Vietnam but is now blank)
Manufacturing Date
Product Code
Available CSC codes
Mobile Operator (there is actually a single comma in this line)
Baseband version
Modem Board
Hardware Revision
IMEI
Samsung serial number (a bunch of zeroes here)
Does it seem likely that the lack of a correct modem file is the culprit for these missing items? I do have the original IMEI number written down (it's also on the back of the phone.)
UPDATE: I tried this: http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 but it did not fix my problem with the IMEI. I did have a backup of the EFS folder but it may have been taken after the damage had been done.
I am currently still downloading the Trinidad/Tobago firmware from Sammobile and will post what happens when I attempt to flash that.
How did you soft brick your phone? You flashed a firmware for other countries? I'm planning of flashing the unknown firmware from Sammobile too, please keep up updated. Thank you.
I once had a problem with the IMEI, but it was because the phone was blocked by the Mobile Company.
Guys really need help here, I just got a used indonesian g930fd (strangely it shows g930f on phone info) which keep restarting itself after upgrading to nougat (OTA). Also even if I already "power off" the phone, it still restarting (or booting?).
I've tried to factory reset from recovery, still keep restarting. Btw at first factory reset, somehow data partition got corrupted then second one success. Also when my data partition corrupted, the phone doesnt restart/on by itself like I mentioned before, so seems firmware related issue instead of hardware.
I also tried to go to two samsung service center, because first one somehow tell my imei is from singapore and second center tell mine is fro arab (wth) so I can't claim warranty eventho still below 1 year.
My question is:
1. Does reflashing stock (7.0) firmware will fix it?
2. Why phone info show my phone model as SM-G930F instead of G930FD?
3. Is it possible to change Product Code? rite now my product code is definitely Indonesian (SM-G930FZDUXID), originical CSC blank, everything else XID / Indonesia . I kinda have doubt now because two service centers tell different country, also sticker on back cover somehow tell its G930F, and print one on glass cover G930FD
Mind me if these question alrd asked before, but I already tried to search and googled everything and Im still lost here.
here's my firmware information from *#1234#
AP: G930FXXU1DQE7
CP: G930FXXU1DQD7
CSC: G930FOLE1DQCV
Model: SM-G930F/DS
knox: 0x0
Thanks a lot!

Hi mate
Well mate , F and FD models have the same hardware and and use the same firmware , only difference is the SIM tray , they are different to fit one or or two sim cards depending on the models.
The model number is written in the build.prop ( do not know if somewhere else) if it only written there phoneinfo can be fooled , you can double check it by checking your IMEI at this site or other similar
http://www.imei.info/
It will tell you to what phone that IMEI was issued to. Check also with phoneInfo if the phone is original or refurbish
to your questions:
1. Does reflashing stock (7.0) firmware will fix it?
Is a good chance it will, if there is no hardware issues
2. Why phone info show my phone model as SM-G930F instead of G930FD?
do not know , check by your IMEI to see what the real model is
3. Is it possible to change Product Code? rite now my product code is definitely Indonesian (SM-G930FZDUXID), originical CSC blank, everything else XID / Indonesia . I kinda have doubt now because two service centers tell different country, also sticker on back cover somehow tell its G930F, and print one on glass cover G930FD
You can flash any F firmware with the desire CSC code , just download the firmware and flash it using CSC and not home_csc

Thanks for ur response! It's still original from phone info, now not tho since I already flashed new firmware.
Things that I already did:
1. Flashing two same 7.0 nougat for Indonesian version (updato and sammobile)
2. Tried entering recovery mode while charging to check if battery dead, result can't enter recovery mode means battery should be fine.
3. Checking serial number with Smart Switch somehow tell me it's from Arab. I can't restore tho since it keep restarting.
And restart issue still there. One thing for sure it does heat up everytime. While on odin mode, it never restart tho. I still can't find the problem
Is there chance for any other hardware failure somehow aside battery? Thanks!

Hi
It's still original from phone info, now not tho since I already flashed new firmware.
The original check in phoneinfo is regarding the hardware , it has nothing to do with the firmware also you can flash a different firmware to your phone and would be still original
1. Flashing two same 7.0 nougat for Indonesian version (updato and sammobile)
What files did you flash?
2. Tried entering recovery mode while charging to check if battery dead, result can't enter recovery mode means battery should be fine.
Not sure what you mean ...if you cant enter recovery while charging means battery is fine, that makes no sense, i doubt your issue is battery
3. Checking serial number with Smart Switch somehow tell me it's from Arab. I can't restore tho since it keep restarting.
I said check your IMEI to see to what device was asigned to , to see if it was assigned to a G930F or G930FD
Is there chance for any other hardware failure somehow aside battery?
motherboard...but if before of OTA was working fine i would think more in a firmware issue

I am in need of some help. I have a galaxy s7 that the efs files have been deleted, therefore, it wont connect to any network as well as unknown base band. when i type in *#06# mt imei number is null (all zeros). I have tried flashing stock firmware onto the device but that doesnt help. I dont know which combination binary software to install because i dont know the correct pda for the device. i am looking for any help to fix this problem.
note: i have another s7 with all the files i think i need, is there anyway to swap the files into the toher device and have it generate its original imei number ?

You need a backup of the efs folder of that device. If you never did one using a custom recovery like TWRP you are doomed. I believe that there are boxes like the Octopus one that, if you know the imei of the device they can flash that partition/folder and assign the device its imei once again. I don't know if the official service will be willing or able to fix the imei issue, I would suggest reaching out to them and ask.

Dear XDA members,
this is my first post, so please be a bit patient if I do something wrong
I got a very stubborn phone from some relative - he complained that sometimes the voice is fading during voice call. Otherwise the phone was working flawlessly, no other issues/trouble, was working across Europe. It was imported to Europe from Asia, which seems to have some importance, but we'll get there.
When I got it, the first thing I tried was OTA update - however there was some error (it still had 5.11 version back in December 2018). Not thinking too much (and not being aware about CSC codes) I got Odin and flashed it with 7.0 stock firmware. At first moment everything seemed fine, but after some time I inserted my SIM-card and I noticed that phone can't register to mobile network - then I tried another SIM-card from another carrier and result was the same. I tried to flash with few another ROMs with different CSC codes - but the result was exactly the same.
The IMEI and serial numbers reported by phone were in line with info on sticker and engraving on the back cover, but then I found that *#0011# shows IMEI Status: NG.
Wondering if the phone is not black listed I checked it's IMEI at imei.info web site and to my surprise it reported different Samsung serial number than the one on back sticker/cover! I opened back cover and I found that the phone has been manipulated, there's no sticker on the battery with phone info, but is some "Chinese" OK sticker...
I searched the XDA-forum and tried various fixes:
1) deleting nv_data from /efs partition in order to restore factory IMEI, etc., (https://forum.xda-developers.com/showpost.php?p=75927733&postcount=37),
2) flashing with combination firmware (https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516 tried both A and B methods),
3) downgrading to 5.1.1,
4) HEX editing efs partition backup to change Samsung serial number to the one reported by imei.info - I replaced sn in three places, phone reports "edited" sn, but I have no clue if it's not causing any checksum errors, I still have "original" backup,
5) repeating 1,2,3 with "new serial number",
6) installing NexusOS-9.
None of the above made it possible to connect to mobile network, checking with *#0011# after each of the above (except for NexusOS) still shows IMEI: NG
Is there any other way that could help that issue? What does IMEI: NG actually mean?
I checked with some phone repair shops, and none of them seemed to be equipped with Z3X-toolbox, at one place I heard that they can try to fix it, but give no guarantee of success, since the phone looks to be non-original.
As I wrote at the beginning - non-original or refurbished in Asia, the phone worked without any issues in few European countries, so I assume that IMEI is not black listed anywhere.
Thank you in advance for any guidance!
