VoLTE fix with Lineage OS if operator of SIM not provisioned - Sony XA2 Ultra Guides, News, & Discussion

## Disclaimer ##
No waranties of any kind given.
This is a guide following a procedure I tested for myself.
If you do not understand a particulary step refer to documentation provided elsewhere already.
## Prerequisites
You already unlocked a device and know what to do.
You are familiar with shell access and editing files.
* OEM unlock possible and code present
* fastboot
* adb (only tested on Linux)
* latest TWRP
* latest Lineage OS build
in case you come from Lineage OS:
* newflasher
* Xperifirm
* latest stock firmware according to your geographical region
## Guide
Reflash stock firmware if you came from Lineage OS or unlock bootloader
Boot into TWRP
Mount system partition
Mount oem partition of active slot
Edit default modem.conf in oem partition according to files found in /system/etc/customizations/modem for your carrier.
In case you already used your SIM before in that phone: reflash cust-reset.ta with newflasher
Insert SIM if not already present and setup phone
Restart to apply customization for your carrier (VoLTE maybe still not working with stock firmware though customization was applied)
Shutdown
Install Lineage OS (all usual instructions apply)

[GUIDE] Enable VoLTE for your non operator handset
I have finally been able to get VoLTE working on my X Performance despite my carrier never having 'supported' my handset (they never sold it here). What you will need? Windows Computer with Flashtool and minimal ADB and fastboot (if you have...

After updating LineageOS 18.1 with built-in updater, my phone was endlessly booting (LineageOS symbol showing for ever).
After following many suggestions, like downloading stock ROM with XperiFirm, installing it with newflasher to slots a and b, sideloading LineageOS again, I finally got the OS running but without sensors and communication devices (WIFI, bluetooth and such). After doing everything again, I have the system running with the sensors and the comm devices but WITHOUT working SIM. :-(
SIM card is recognized, PIN excepted but no radio, i.e. connection to the cell. I get "No SIM card" and I can't connect.
I very much hoped your solution can help getting back to normal but can't since it is very brief and files like modem.conf or /system/etc/customizations don't exist on my phone (at least "find" doesn't find 'em). I can't mount oem partition since TWRP doesn't give me the option.
Could you explain a little more why you had to find that solution in the first place and how exactly you fixed it?
Thank you very much! I'm sure other's will benefit as well.
(I'm a little verbose here because I hope that finding this site is easier with more words in it. Once the explanation is refurbished, many people will be happy.)

Sounds like you forgot copy_partitions.zip referred in Lineage OS installation instructions maybe?
I somehow remember this problem in a different context.

I tested with latest generic uk firmware and modified modem.conf only present in oem partition of stock firmware while trying to figure out the whole process. Applying settings needs to be done on stock firmware this way.

I found no way of modifying required settings in modem partition otherwise so far while thinking about a more generic way which could be applied in Lineage OS directly. Switching SIM / carrier involves applying configurations to baseband which need a reboot so far discovered. I cannot replicate this in Lineage directly.

Thanks for help, xcalc.
I did sideload (ran) "copy-partitions-20210323_1922.zip". No SIM anyway.
I couldn't modify the files you mentioned since I couldn't see them. Couldn't mount oem partition.
I didn't even switch the SIM card. I've been using the same for many years, different phones, different ROMs.
Anyway, thank and take care.

Sim Card Not Detected.

After flashing lineage OS and even resurrection remix, phone is unable to detect sim cards.
SIM cards are detected once I restored the TWRP backup file, but aren't detected on flashing lineage and resurrection ROMs.
Please Help
same issue here, lineage wont work, will flash back to stock so the phone is usable
Flash again oraz try another rom

fastboot devices
fastboot oem unlock-go
fastboot erase modemst1
fastboot erase modemst2
That is the most context-less answer I've had in some time.... "unlock bootloader and erase modems firmware" written in commands.
Device is unlocked, that's why it has lineage...
Now why would erasing modem firmware solve the issue? Was I supposed to blindly erase firmware and do nothing more to solve the problem?
I actually solved the problem by flashing a 26s extracted firmware for my china region x520. I am using g it in Europe. I am not linking the firmeware for 2 reasons: 1. Firmware is closed source/leeco proprietary and 2. Posting might induce non-x520 users to flash and have the same issue I had because of flashing wrong firmware. Even here this firmware is not 100% ok as I had to change a build property for getting calls audio (fluence to none, I think thisbis the VoLTE issue). Anyway, if someonr here has issues, flash your original twrp backup (hope u had one, i accidentally deleted mine from my work pc due to space needs). Or else youre gonna have to find a stock ROM/firmware and bite the bullet for the 1.6GB download. AND IT HAS TO BE FOR YOUR SPECIFIC LE 2 MODEL (e. g. X520, x525 x527, x620... If it isn't you will likely not have SIMs/imeis or call settings will orevent u from having sound due to VoLTE support failure)

Maybe you should do some research about the given commands and what they are doing.
Sounds like you do not understand these commands?
Is there really any difference in the extracted firmware from version 26s to e.g. 21s?
Someone wrote there were no updates in modem firmware since 20s or 21s??

Ok sorry !
Were you replying to me @JamBax?
Anyway, I have no idea about the latest modem images already being in 21S. All I know is most people consider 19S as benchmark for telehpony and VoLTE, since 21S apparently has trouble with VoLTE. I don't doubt 21S is the last one available though, and there might never be a new one. Cheap hardware companies will usually have in-house devs for their custom AOSP, but mostly use manufacturer provided hardware-related stuff (such as modem firmware) or outsource it, so those reach support cycles faster. Granted, it doesn't need so much revisions and polish - the more contained features make it easier to reach its prime. The hardware simply won't improve with code up to a point.
I flashed 26S because it's what I could find in a package that was extracted from the entire so-called "firmware" around this XDA subforum (stock ROM aka manufacturer ROM aka EUI). Saved myself downloading 1.5+GB on a data-capped 3G I currently am using.
I'm likely not gonna try 21S/19s or any other endeavor in this x520 as all I wanted was to have the phone ready and usable as a birthday gift. The present subject will likely never use VoLTE in the life-span of this phone, since we don't have LTE on our village anyway and 2G is staying up for at least 4 more years. They are just happy they can now use Facebook much better than with their old 4.5'', 3y-old crappy Huawei (you know, before they could make half-decent chipsets, even now I still think they suck despite topping synthetic charts for CPU. From personal experience, I still can't trust the performance of any chinese chipset, be it Mediatek, Allwiner, Huawei or Xiaomi, and the only asian-designed thing I trust is, obviously, Exynos).
P.S: the phones were used today to make at least 10 calls successfully. I did not try dual SIM though, single SIMs only. Didn't switch any telephony settings either from the standard menu or the hidden test menu, so I take it the phone is doing 2G calls.
No issues on my side
I have installed Lineage OS 14.1 official, and I have no issues with sim card detection. The signal strength is weaker, but it gets detected at least

G610M - AOPS ROMs - No SIM Card / Service

After flashing 610M (csc: TPA) the phone shows "No sim - No service", even tough in sim card management it's there but no carrier is shown.
I tired:
1. IMEIs were there, but I still tried to restore EFS
2. Tried both sim card slots (the second one can at least receive messages, rather weird thing)
3. I tried to flash CP and CSC trough Odin after installation
4. CSC Changers do not work: errors
5. Tried to install similar ROMS: ResurectionRemix, AospExtended and crDroid... same problem over and over
6. Tried flashing latest Oxygen kernel v.5 - no luck
7. Tried installing without GAPPS - no change
8. Tried flashing latest modem from 8.1 official - nothing
Please, help me good people, I'm out of ideas. Currently using Millennium ROM, everything works. No possibility to buy a new phone, but I miss the simplicity and snappiness of AOSP roms. Thank you.
EDIT1:
I found out that even after flashing CSC in Odin. PhoneInfo app shows that there's not CSC or CSC firmware at all. Attached screenshot.
Have you tried checking if your IMEI numbers are blocked in your country?. Could be blacklisted by an operator.
From which state you are probably problem in restricting the device

I use Millennium ROM (which is non-AOSP) right now, and cell service works perfectly. I can try checking of course (will reply later).

Weird, I have the same model as you and I've flashed a few AOSP roms (Havoc OS, DotOS) and no problems with my signal.
Well, if it works in TW, then it could be the radio firmware in the AOSP roms that is causing the problem with your signal. Im not sure how you can flash the radio firmware once you are in an AOSP rom, but you could try making a backup of the radio related partitions with the Millenium ROM installed and then try to flash the backups once you flash an AOSP rom.
Make a full backup just in case something goes wrong.

Thanks for the reply. I did try to restore EFS and Modem partitions after flashing DotOS, but no luck. I looked at the *#*#4636#*#* menu; and there's a signal (decibels change). It's like it doesn't read SIM cards (I've tried another one with different carrier).

MOTO G6 - IMEI 'Unknown', Baseband 'Unknown' - NEED HELP PLEASE!

Hello everyone, I am new to all of this development stuff for Android devices and I know I screwed something up big time.
I had an update recently on my Moto G6 XT1925-6 phone to Pie and there were several bugs happening from calls dropping, data and service dropping erratically, youtube videos would skip forward several times or not download at all. I found the post on here to downgrade from Pie to Oreo Stock ROM and followed it exactly as I could. Everything went according to the guide, but now after rebooting the phone and going through the setup, the phone wont detect my SIM, and there is no service. Under the IMEI Information, everything is 'Unknown' and under SIM status everything says 'Not Available'. Also, under Mobile Network, Data Roaming, Preferred network type, and System select is greyed out. CDMA subscription is the only thing available to tap. The issue with that is, this phone is originally GSM.
Please, I am not knowledgeable in messing with Android systems and I know I shouldn't be messing with something I know nothing about. I do have ADB Minimum installed on my PC, the phone is unlocked bootloader but is currently not rooted after the stock ROM was flashed.
Stock ROM: ALI_RETAIL_8.0.0_OPSS27.104-92-4-5-1_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
One more thing to add, I did the fastboot IMEI check command and it came back with one IMEI so it is still present in the phone somewhere.
Any help would be greatly appreciated! Thanks in advance!

What version of Pie did you upgrade to and when you downgraded did you flash the bootloader and gpt.bin files? Can you link the post that you followed?

First, thank you for your reply and help in this matter!
After the update from the phone itself, it said it was Android Pie v9.0.0. I don't know anything further than that on which version of Pie if there are several.
When I attempted to flash the bootloader and the gpt.bin during the steps on the forum guide, adb gave me the 'couldn't open' and the 'Failed' result for those two things. Reading one of the replies to this guide, someone stated that they didn't flash either of those and it worked perfectly.

I have successfully downgraded from Pie PPSS29.55-24-2 to Oreo without flashing those files but today when I flashed the newest Pie PPS29.118-11-1, I got these results.
Only solution was to reflash the latest Pie. If you took the OTA update as it appears you did you are most likely in the same boat I'm in stuck on the latest Pie.

Okay, thank you for the information. Unfortunately I will have to reupdate to P.O.S. Pie. Could you point me to the correct version of Pie that will work? It was the OTA update to PIE that I did so if you could let me know which one you labeled would work, then I can get started. Maybe point me to a guide if you know of one to do it properly.
Thanks a million!

I can't tell you exactly which firmware to download, but It looks like you are using the Retail version by your post mentioning "Stock ROM: ALI_RETAIL_8.0.0_OPSS27.104-92-4-5-1_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml". If so I would flash this one.
As for a guide some people use RSD lite but I prefer this method.
download the attachment and extract it
extract the firmware to the folder Place_Extracted_Firmware_Here.
double click 2-rsd-flash-flashfile-windows.bat, this will create a file called flashfile.bat (It will Wipe your data).
boot your phone to bootloader, connect it to pc.
double click the flashfile.bat and let it run
reboot
hope this helps

SM-G900F - Need original firmware

Hi guys,
My S5 was on 6.0 and have upgraded to 9 Pie but something went wrong (or I screwed up something) and I need to re-upload the original firmware, unless you have better suggestion.
Currently, I have TWRP installed as well as Android 9, however, when I turn my S5 on, I get: Set Warranty Bit:Kernel
It stays there for 30 secs then the phone boots up and everything looks fine, it connects to wi-fi etc.
One other strange thing is that I get a message on the home screen saying: unsupported SanDisk SD Card
I tried a new one, same message.
Before I started this process, I connected the phone to my PC and copied both the Phone and the Card folders, so I am good, data wise.
Basically I was thinking to go back to the very first OS, I think 4.4.2 and then re-load Lineage 16 using TWRP.
If I read the baseband version # is: G900FXXU1ANCE
If the procedure above is correct, would you be able to provide me a link to download the firmware?
I tried all the known sites, but their speed sucks, so I thought to ask here as somebody may have a link.
I will use Odin latest version to install it.
Thank you!
Alex
Access to the original/official firmware for SM-G900F would be extremely helpful for me as well.
I'm running LOS 16 with pico GApps very happily on my S5, however I have mobile data connectivity issues. Data connects and disconnects at random; this is device-dependent (swapping the SIM into other devices gives fully functional data connectivity).
My baseband is G900FXXU1BOA3; I believe updating the modem might fix this?

Fox, you may download the official firmware at https://samsung-firmware.org/model/SM-G900F/
Select your region to get the right ***.md5.tar file to flah via Odin latest.
This will reset your handheld to out of box - original recovery reinstalled - you must reflash it also via Odin if you want to go back to custom Rom..
Good luck
.
Thank you.
What would be my region?
I purchased it in the US unlocked, but US is not a choice when it comes to region.
Would I be able to see the region the phone is from from the baseband #?

If your reference to the baseband version# is correct -> G900FXXU1ANCE, then the region is BTU -> check this address to download the original firmware:
https://samsung-firmware.org/downlo...agon-__/1806/BTU/G900FXXU1ANCE/G900FOXA1ANCE/
After flash via Odin, reboot and optional reinstall TWRP via Odin to use other custom Roms.
Are you sure you did everything before resuming to scratch. Personaly I would have done the following:
- back up in TWRP (at least data) + back up in google drive if you use google or titanium, (anyway save your picts, ...) if rooted, it is possible to save the file containing SMS, ... search in XDA,
- format (not wipe) !!!! WARNING THIS WILL ERASE ALL !!!!!
- clean install the ROM (lineageOS or else) + optional Gapps (I use Pico),
- reboot and restore data (as shown in 2 above)
(The Roms I use on my two KLTE by personal preference order are Havoc, DotOS, Bootleggers, Resurection Remix, MSM-Extended. I also use LineageOS.

That site is very buggy, if I search my model and enter all the other info I get to Lollipop 5.0, if I click your link, although I am registered, it does not allow me to the link you provided, I mean I can get to it but when I try to login, it takes me back to the home page, so there is no way to get to your same link while being logged in.
How do I get do the download page it is a mystery to me.
Also, how do you know from the base band that it is BTU region?
Thank you

Men, the subject of resuming to firmware has been discussed and is described in the net literature! e.g. in XDA Q&A.
This discussion is now not a thread anymore but a dialog and I’m sure it will be closed by XDA moderator for redundancy.
The warnings given when you flash a custom Rom are clear. It also implies “before all” to backup, but also keep all materials to resume to original firmware, …. Now I cannot help anymore because you have problem with downloading the firmware.
Last advice – google baseband# - there are probably other web options or torrents
!!!!Also use the thanks button!!!!

Before I started this process, I connected the phone to my PC and copied both the Phone and the Card folders, so I am good, data wise.
Basically I was thinking to go back to the very first OS, I think 4.4.2 and then re-load Lineage 16 using TWRP.
If I read the baseband version # is: G900FXXU1ANCE
If the procedure above is correct, would you be able to provide me a link to download the firmware?
I tried all the known sites, but their speed sucks, so I thought to ask here as somebody may have a link.
I will use Odin latest version to install it.
Thank you!

1. Its normal to have the "Set warranty: kernel" text. As my device does too. Just simply ignore it. It won't harm your device.
2. Basically you can search websites that had official Samsung stock firmware. Search your region of your device and (IMPORTANT!) your model, in your case, is G900F. (Wow same as mine but different region, Snapdragon rocks).
3. To your network problem, I think you need to wait. There is no other option.
Thanks!

XDA forums has one. Tip: if your region isn't there, the replies have all the filmwares you can have.

Men, the subject of resuming to firmware has been discussed and is described in the net literature! e.g. in XDA Q&A.
This discussion is now not a thread anymore but a dialog and I’m sure it will be closed by XDA moderator for redundancy.
The warnings given when you flash a custom Rom are clear. It also implies “before all” to backup, but also keep all materials to resume to original firmware, …. Now I cannot help anymore because you have problem with downloading the firmware.
Last advice – google baseband# - there are probably other web options or torrents
!!!!Also use the thanks button!!!!

I have downloaded the firmware and this evening I will try to upload it and see what happens.
I still I have no answer to my question: how did you figure out that my firmware is BTU?
I mean, I gave you my baseband version #: G900FXXU1ANCE and when you eventually find it in any firmware sites you are given the choice to choose among many countries, expect USA and Canada.
Since I bought the phone in the US I still wouldn't know which country the firmware is from.
Would you mind to shed some light on this?
Thank you!

Thank you for your feedback John.
I am not sure that message is normal, if you google it they all say it is an issue with the firmware and that you need to go back to the stock one to fix it.
Is there anyone else with lineage having that same message?
Also, when I try to format my SD Card, it gets stuck to 40% and then it goes to the homepage.
I tried also a brand new card, same story.
It gives a message but it goes away after a few secs., I believe it is a Java message, but I can try again and take a picture of it.
Thank you,
Alex

I tell you my experience:
No matter the country you bought your device. As example, I leave in France, I bought mine in Hong-Kong, but choose an international device (G900F).
Before flashing anything, I checked all information in settings and recovery.
Pict below is original out of box G900FXXU1BOC7
Recovery information after latest update G900FXXS1CQD1
It happened recently 2 times my device was stuck because encription issues – I recover by reflashing original G900FXXU1BOC7 via Odin
I personally downloaded firmware as G900F – BTU, because I check the version at each updates and this sticked to BTU ONLY.
May be the site SamMobile will be more meaningful for you, because you see Countries/Operators and updates history.
https://www.sammobile.com/samsung/galaxy-s5/firmware/SM-G900F/BTU/
For your device, you have to grab the search to find the closest original (which you have) to latest update (if you have it).
For the Kernel yellow tag at warmup, this is done when you flash TWRP. No issues since 2 years operation with that using LineageOS, Havoc, DotOS, AOSP, Bootleggers, RR, ViperOS. If you flash original firmware, it will disappear because twrp is erased and original stock recovery flashed.

When it said that you go back to stock one to fix it. Then want if it is not stock? The message is still there. Its normal if you want to install a custom ROM other than the stock one. I reinstall the stock and install custom ROM again once. It still happened.
I don't know how to remove the text but still have a custom ROM tho.
As for the SD card message, I encountered times before. Maybe you need to format using the computer.

When I reflash the stock ROM TWRP is still there. However no "Set warranty: kernel" appeared. Maybe its just when you install a custom ROM or something, I don't know.
OK guys,
Lineage 16 is installed, everything went smoothly, however when I connect the USB, the phone just shows as 'SM-G900F' on my W10 PC and cannot be expanded, basically no Phone and SD Card folders.
I can see them in the phone no problem, but once I connect it, I am not prompted with the usual message on what I want to do, like file transfer etc. and on the left menu appears only the model of the phone.
I had no issues when I flashed the original firmware, so it must be related to Lineage.
I also installed the Android USB drivers, but no go.
Changing the USB Preferences, to PTP or File Transfer only allows me to see the phone, no SD.
I also tried a new SD, no success.
I am stuck again... Jeez it takes days to get this stuff to work, you do one step ahead and another back
Ideas?
Alex
Anyone?
Shall I ask the question in the Lineage section?
'Set warranty :kernel' means you are running a custom kernel. Any modified boot.IMG can cause this message. It doesn't mean you need to use stock room. This appears even in stock rom with magisk or SuperSU.

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?

By root device and download Root Explorer, browse to the efs folder the delete everything EXCEPT the 'FactoryApp' and 'prov_data' folders it should restore IMEI
