Help! - Samsung Galaxy Note 8 Questions and Answers

Hello guys!
Six months ago I bought a used note 8 SM N950F once I tried to install another rom (custom one) after backing up the whole mobile by twrp, after installing the rom, the phone couldn't detect sim cards and imei, when I returned to the backed up rom everything were fine.
I searched for my phone's imei and the result was these imei numbers belong to another samsung device, samsung ace I think.
What is the problem? I can't use any rom exept the original stock rom which already installed to this device, help me finding a solution to install another roms with working sim cards.

Which ROM u tried? And also did u make a backup of efs?

Could I make an EFS back up and use this back up for the other rom?

Yes i think it can be done
... Quite a few tutorials to do that online. Go ahead and Google it.... I have not done it myself. So i will not be held responsible if anything goes wrong. But it should work. All the best.

You need to return that device immediately it's never going to work you cannot use ANY efs folder from ANY other devices and even if they do flash they will not work!! Stop wasting your time and send it back!!

[Q] Galaxy S, sim card doesn't work after flashing rom

Hi everybody,
yesterday I flashed my phone with the original rom it was shipped and now the sim card does not work. The phone was network locked and I'm afraid that now it does not recognize any rom because of this.
I tried to do the procedure of simlock by rooting the phone but no codes appear after I launch sgux in the file.
Does anyone know how to solve this problem?

it could well be that your sim is dead if you left it in the phone while flashing. happened to me and it was quite weird, i could make and receive calls and messages, but 3g was dead. the guys at the 3 shop were quite amused as they have not seen anything like it before. anyway, try the sim in another phone, see if that works. ultimately flash to an unbranded rom and try a different sim on your phone.
Hi... I need some help please...

You say you have the original shipped rom .
If thats the case just flash that back if it truly is the original shipped rom .

Darky rom problems as usual ask the chief suspect .Its probable you did not flash correct CSC file for your network .

Samsung I9000 Galaxy s doesnt recognize sim card

Hi everybody.
I got this weird problem with my cellphone. I have an international I9000. after factory reset my phone doesnt recognize sim anymore. I tried it with other sims too but my efforts were not successful. I tried flashing with other roms but again nothing happened. what am I supposed to do now? have you ever had the same problem?
Hi i have had the same problem when i flashed my phone, if you have a backup you need to copy the EFS folder back onto your phone as it contains your phone info emei modem details, if you do not have a backup then you will need to find the original rom for your phone, do a search for EFS and EMEI on here there is lots of info on this problem. good luck and the best of regards....
thank u very much buddy I have tried flashing with xxjpu but the problem still exists. what do u exactly mean by original rom?
Help me please guys

Flashing an official ROM should not mess with your EFS. What do you mean you lost your GSM network? Have you checked your APN?

The ROM I was using was flashing with cloned IMEI after flashing my N920C with fresh version of official ROM the GSM network is gone and when I install my Sim Card it is shows only "emergency call". I checked while the IMEI is gone or not and saw it is still there. I need a solution for activate GSM network and see GSM signal. Some of my friends said that my ./efs file is corrupted so I need patched ROM that can fix my ./efs file automatically after flashing. Is there any why to recover it ?

I understand your situation now. As far as I know there is not a way to recover your EFS. I could be wrong. I have heard of others getting their EFS back after flashing official firmware. You may be out of pocket on a repair. Good luck to you.

I am sure Samsung can fix it. You will have to pay though. You could also try searching for efs recovery because you might get lucky. I do not know a whole lot about it but from what I have seen, if flashing official firmware does not fix it you are out of luck. I am not sure about future releases of ROMs that may fix it.

Thanks for your replay. I fixed my phone and its working now. I did these steps:
1- Untar the official ROM.
2- Delete Modem file from the rom.
3- Re-tar the ROM.
4- Flashing using Odin.
5- Fixing EFS by repairing it using z3x box.
Thanks again :fingers-crossed:

URGENT: Re-installed Stock Firmware (update-6.0.1) - NO NETWORK ACCESS

Hey, everyone, I need some help:
On my SM-920G, I re-installed stock 6.0.1 (last official update before 7.0) and, now, I don't have access to the network (says emergency calls only). IMEI and serial number are both intact. What can I do to regain access to my network? I know it's not a motherboard problem because it happened after flashing stock software. I WOULD REALLY APPRECIATE YOUR HELP.
Thank you,
VinceLupe

Did you install the right firmware for your region? You should check that or flash right modem file. If all else fails use kies to restore phone to factory or flash a custom rom and check if everything works.

So, I actually had to have an IMEI change... Long story - but, my question now is: is it possible to return to stock (completely stock) and NOT lose my IMEI number? I've heard some people say, "yes," and O be heard some people say, "no." Is it possible?

I don't think there is any risk of losing IMEI if you flash stock with odin, but if you have root then firstly take an efs backup, just in case, efs is where your IMEI is stored.

If you have root then in the root folder you will find a folder called efs. Just copy it and save it to your SD card or your computer. If you have custom recovery then you can save it from the backup option but I guess that won't help much if you flash stock with odin then it will remove your custom recovery. There are also some apps on the play store but I never used them, I use the first method.

Yeah, I'm just on stock, so that won't work - but, now I have another issue:
So, here's what happened... I got my IMEI changed, and all was good. But, then I realized that my phone was rooted. I tried to flash magisk to have magisk installed, and then my phone wouldn't boot up. Afterwards, I flashed stock to restore official device status, but when I did so, I realized that my network wasn't working. My IMEI (clean IMEI) is still showing, but I DO NOT have any access to my network and can't search the web or anything. What could be the issue, and what is the easiest way to fix it?

Did you flash the correct firmware? The same region as it was when it was working? Flashing a stock rom from a different region sometimes causes this and you need to flash the right one or at least the 'modem' file of the right one to get it working. Or you could use Samsung Kies software to completely recover your phone to its original state when it was bought. Also, What do you mean by saying changed IMEI? Did it not show it correctly or got corrupted and you fixed it? or you changed it completely to a different one from the original?
If you have a good IMEI just call your provider and give them your IMEI and your sim card numbers.

CodeNameRedNeck,
So, I have a good IMEI number, but I cannot register the network service. It tells me "Emergency Calls Only" even though it shows a signal in the top right hand corner. Are you saying that I just need to call TIGO (I am in Bolivia) and register my IMEI number as well the SIM card numbers - or, could it be that there is an even deeper issue? Also, which SIM card numbers are you talking about? Thank you, my friend.

Mufrad,
I completely changed the IMEI to a clean one because, apparently, when I traded for the Note 5 (I am in Bolivia, and that's what people do here), the original IMEI was put on the blacklist. So, now I have a completely different IMEI that is clean (unreported), but I do not have any network access at all - furthermore, when I access the menu using *#0011#, it says "IMEI Status: NG" under IMEI Status. I'm not sure if it's a software problem? I have a friend looking at the phone, but I do not have any idea how it's going because he still hasn't been able to fix it.

When my son switched from an iphone to Android we had to call AT&T and give them those numbers before it worked. I had an Xperia phone that I had to do the same with. There are apps that can read your sim card number. It should also be printed on your sim card.

loose imei, not detect sim card

Hello,
I'm french, excuse my langage...
I have 2 note 8, an N950F (single sim) and an N950FD (double sim). I specify immediately that the 2 have already worked and that I have only one sim (one being for me and the other as a gift for my wife lol)
- On the N950F, install via odin 3.14 of twrp 33.1.2, then hadesrom 12 then magisk 20.4 => everything is ok
- Purchase of the N950FD, hassle with installing twrp because I had to put my sim in it to change the time and have access to the usb options, in short, it works, then same as hades and magisk => everything is ok
I have well customized the N950FD, I made a full save (all partitions) with twrp and I said to myself I do a full install on the N950F ...
At the time I did not watch out ...
I calmly use the N950FD and then, I still hack the N950F, I install other custom roms to see, lineage 17, etc etc and all that I do it without sim, with the dex dock connected in ethernet, in me saying that when I'm done, my wife will just put her sim there ...
And then something bothers me, it's a small prohibition logo at the top left instead of the network. I tell myself that this is normal because I did not put a sim, so I take that of my N950FD and there bah it is not recognized ...
I do not panic, I tell myself that I made a false manipulation, I wipe, I reinstall hadesrom and same concern, I take another custom rom and same concern ... I redo a full install with twrp and same concern .. .
I take a stock rom (the last, then the first, always in 4 files either with the csc or with the home-csc), I flash with odin 3.14 and 3.13 and always the same problems, the rom remains blocked on the screen samsung, the first with "samsung note 8 powered by android". So I tried the last rom with 3.14 and 3.13 then the first and still the same problem, it does not start (I waited 5 minutes roughly) despite the wipes ...
Since I no longer have twrp, I reflash, it works, I tell myself that the custom was still installed and I reflash via twrp hades (I tried the stock rom file but it didn't work) and again same concern, the sim is not recognized ...
I try the flash of the hades kernel, it works but the sim is still not recognized ...
When I go to the phone * # 06 # I do not have imei, but a black screen, when I go to parameter / connection / sim card manager => black screen with the message "com-android-phone does not respond" ...
I looked a little on the net, but nothing conclusive, I specify that all my files come from XDA but that given my English I prefer to try to find an answer in French ...
I do not have a backup of the N950F it would have been too simple, I tried another sim than mine but ditto it is not recognized and before making a tablet I would like to try everything to recover it. ..
It would seem that flashing a stock rom solves the problem ... But as said above, my phone remains stuck on the samsung logo despite the wipes
I still tried other things like just flashing parts of a stock rom but I still have the same problem ...
I also tried the flash of a stock with the extra pit and the nand erase and distribution options ... and similar, no start ...
I even reinstalled twrp after a stock, save it, "mix" it with another backup I had (efs and modem from the stock and the rest of the custom) but then again, it doesn't work, such reboots well but still no network access and no recognized sim card ...
Finally, I looked at chimera tool, but no tutorial in French so no way to see how it works or if it will meet my need ... taking an exclusive samsung license on chimera does not cause me any concern IF it allows me to do other things than what I have already tried ...
I also looked at the prog to change the imei because there is nothing left, not even 0, no no, a black page just like when I go to the sim card settings, I have a black page. ..
I also flashed several custom roms from different countries but it didn't work ...
By cons I observed that I had the location for 2 sim, still inactive ...
How to put the note 8 in single sim and recover imei and then the network ???
there, I block ... if you have ideas I am taker, thank you all ...

If you didn't take a backup of your /efs folder which is where all of the phones important information is stored such as your IMEI then you are screwed because you can't flash any other phones EFS FOLDER.. However if you have a backup efs folder, restore it.
the concern is that I do not have a backup of the efs file ...
is it possible to put an efs file of another note 8 n950f and where to find this file on the net?

MrMike has already answered this, you can't share or use any other EFS.
The fact you can flash a custom rom and it will boot tells me you don't have a hardware issue, try flashing stock again as this can sometimes fix the EFS file, it has done for me in the past and a few others users. Although I can't tell you why you get stuck after flashing stock, this is the best way for you to hopefully resolve your issue as you don't have a EFS backup.
Except by flashing a stock, is there a way to restore the n950f to factory condition?
because with odin, if I flash the last stock, it does not start even if I make the wipes and if I try an old stock, odin blocks ...
can the chimera program allow me to find an original n950f?

Not that I am aware of, I am only aware of restoring by flashing stock with Odin or by using Samsung smartswitch.
You can't flash older filmware than what is already on the phone, that is why Odin is blocking that, but when you flash the latest filmware does Odin give you the green pass?
I am not familiar with the Chimera program so can't speak on that.
Yes with odin I have the green pass, but then the note 8 does not start, it remains blocked on the logo, even if I do the wipe ...
I even tried to save right after with twrp and recover the efs but it does not work ...
If I find a broken Note 8 can I recover the efs file by saving it and then putting it on my own?

Thanks for your help, how to start it in stock rom?
I specify that it starts in custom rom ...
the first photo is before the installation of the stock rom with odin, the second is at the end of the installation (odin ok, pass in green), the third is after the restart which has not worked (blocking on samsung note 8)

Could you please explain to us all in here how you're going to fix his /efs folder when he never made a backup of it.. Where are you planning on getting him an /efs folder that held all of his phone's information when he accidentally deleted it?
