Hello guys,
I have Samsung Note 9 (SM-N960F) and updated to Pie.
I usually use custom ROMs.
Recently after flashing a new custom ROM, I lost IMEI and signal.
To fix the problem, I flashed stock ROM successfully but IMEI is empty (UNKNOWN). There is not network signal.
I have previous custom ROM TWRP Backups. I restored to the old TWRP backups. But still the IMEI is UNKNOWN and no signal.
I had efs backup of a custom ROM as efs.img. I tried to restore it using Partition Backup app and terminal but no success.
I flashed Alexander's ROM (DEV BASE) as indicated in this post:
https://forum.xda-developers.com/galaxy-note-9/help/lost-imei-please-help-t3847336
But still the IMEI and the signal problem is not resolved.
If you have any idea, please help me fix it.
Thanks.

what fine model you have?
anyways flash back full latest stock firmware for your device and ull get back imei.
use frija or samfirm tool to quickly download firmware.
when you flash dled firmware with odin, flash all .md5 files. also flash csc.md5 instead of home_csc.md5
if you fully flash latest October/November firmware as suggested it will work.
if you skip steps or don't use the latest files then it might not work.
once back on stock with signal, follow dr ketans guide for OEM root fix as per his pinned topic in the note 9 general discussion forums.
then flash back a recent custom rom.
suspected cause of your problems:
-modem mismatch with device model
-modem mismatch compaired to rom base
you should always flash/maintain BL and CP manually with Odin and never through rom zips. and always read rom OP regarding modem and bootlaoder.

Thank you for your info.
Currently I have slow internet connection. Anyways, I have started downloading the latest firmware using frija.
I will let you know after flashing the latest firmware when the download completes.
Thank you.
Exact same thing happened to flashing the same rom. Made my sim cards not detect. My phone has been down for a week. Finally have a day of work yesterday and fixed it by flashing stock bl, cp, and csc then flashing back to tgp rom.

Thank you bobber10113 for your guide.
I followed your guide and downloaded October firmware update and flashed.
But the problem is still there. No IMEI, No baseband.

Previously, I flashed October update. The flashing process completed successfully but the problem (IMEI & UNKNOWN) was not resolved. I posted the problem is not resolved here.
Then I downloaded another more recent update from another region and flashed and the problem is gone. My phone is full life.
Thank you bober10113. You helped me fix this problem.
Thank you m. murray too. I appreciate your help.

Hello guys
I used the mini tools to root my phone.
Installed BLN kernel without any problem.
My phone is on I8190LUBAMA1 and CSC I8190LZTOAMA1
i was looking at samsung-updates.com and saw some other firmwares newer than my stock.
Is it safe to download and install the firmware I8190LUBAMG2 ? Is marked as an Mexican firmware(I live in Brazil).
Installing this new firmware, do i lose cmw, root?
Thanks
Sergio

Hi Sergio, it is safe to install the mentioned firmware, however, consider that you are going to lose CWM and root. Furthermore, as the firmware is Mexican, it contains local apps. So, if you are planning to move to this new firmware I suggest you to after do it install the cwm again through Odin and then a Custom Rom in order to get rooted again and remove those local apps. Regards
Reyesteban,
So if i install this firmware, it will update kernel and baseband, right?
Later, when i install a custom rom the kernel and baseband will be keeped from the mexican firmware?
The installation for the Mexican Firmware should be done via Odin? or i could use CMW?

The Firmware, as it is an official one, replaces kernel, baseband and even the boot screen and you just can install it through Odin. And you are right, when installing the custom rom, kernel and baseband will keep the same. However, boot, rom apps and look&feel are going to change...
Hi I'm trying to flash the T-Mobile firmware from sammobile.com, but whenever I try, I get an error at 32% when it says Installing System Update. I attempted to flash CSC,AP,BL, and CP with it saying PASS in Odin. I really need the T-Mobile firmware and am wondering if it is possible to do? I determined that I cant install CSC files and get the error when I try. Any Solutions?
SM-G950U
Odin 3.12.3
T-Mobile Firmware:
PDA: G950USQU1AQD9
CSC: G950UOYN1AQD9
I'm having the same problem with an ATT phone flash with the US "U" unlocked version firmware. When I don't flash the csc it will start up only with the USB plug in but shut down after the beginning startup
Search for a "modified Odin". It was what I used to be able to flash unlocked firmware on a 7 and 7 edge a few months ago. The "normal" Odin wouldn't let me do it, but the modified one did. Though you may need to wait until it's been updated....I haven't checked it in awhile.
Still no solution to avoid the error to 32%?
Try this Odin. This is the one I used to flash the Canadian firmware on mine.
I managed with odin version 3.12.5! But only with BL AP and CP!
When I add CSC I get the error at 32%!
So a priori everything works, I no longer have the Verizon overlay (nor the logo at startup) more by cons I have duplicates in the settings menu ...
What is the CSC file?

The Canadian firmware you got it or? On sammobile I find it not:
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/
The Canadian firmware is stock or operator?
I would have access to all the bands?
Its the firmware with the "w" at the end. Please read this thread for all the information on doing this and make sure you want to do it.

so to do this we actually have to go to the canadian firmware first, do the csc change then flash the Tmo firmware? You can't just flash the Tmo Firmware via the modded Odin? Just to save confusion.
I would imagine it's worth it just to get the proper network options, VOLTE, WiFi calling and such.

This is the exact thread that I used. Follow the steps and you can skip engboot. If you flash the full Canadian firmware, its impossible to reverse. So, only flash whatever is in the steps. I successfully went from Verizon To T-Mobile and then back to Verizon. https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
This tread also helps, who wants to flash their phones: https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
I have been reading all sorts of threads for the past week on how to do this correctly. I think I got it down, just need some confirmation.
I got an international Note 8 SM-N950F 128GB.
I updated to the latest SW via the OTA - Baseband: N950FXXS4CRG6, Build Number: R16NW.N950FXXS4CRG6.
During Setup, I did not put in my SIM at all, I Logged in to the samsung and google accounts.
Waited 7 days and now have the OEM unlock option available.
I want to use the device on USA T-mobile, and root the device and install Xposed and Viper.
Can this be confirmed as the correct work flow?
I will be following Dr. Ketan's Guide to Root and Backup EFS. https://forum.xda-developers.com/galaxy-note-8/how-to/guide-how-to-root-note8-efs-backup-t3677038
1) Flash TWRP via Odin
2) Flash the OEM Unlock Fix, which should also install Magisk.
at this point, I shall boot into the Stock ROM and ensure the OEM Unlock is available, and Backup the EFS partition using the app from Dr. Ketan's post.
Question is: at this point, after backing up the EFS, I can flash a custom ROM, correct?
3) Backup EFS
4) Install Custom ROM.
- I am thinking https://forum.xda-developers.com/galaxy-note-8/development/rom-lightrom-t3768385
5) Flash the Tekhd Tmobile CSC Detonator https://forum.xda-developers.com/ga...ent/n8-s8x-s9x-oreo-t-mobile-efs-csc-t3772374.
A lot of Roms state they support Multiple CSC's. So, would this CSC Detonator be needed?
5) At what point in time Can I update Magisk or TWRP to the latest ones?
I just want to end some confusion I have. If you all on T-mobile can tell me the steps you took to get this working, I'd greatly appreciate it! Thanks for all your help.

hello,
any update from your effort to get volte ?
i think if you are on oreo, just need to flash the current detonator version for note 8 and see if it works. you can only use 1 CSC file (either multi or not) per phone.

I would like to do the same thing. thanks in advance.
I have a ATT s7 edge. I was running on g935AATT4CRE4. Oreo. I found a firmware that was a 935U firmware. I flashed it with Odin with no problems. I liked it a lot. I wanted to go back and compare the 2. I know, kind of dumb. I had issues flashing original firmware listed above. I did some research, I downloaded latest att software and flashed it. Worked fine. Here is Build number G935AUCS8CRK1 . Now I cannot go back and flash the 935u firmware. I have noticed the 5th digit from the end is now 8 and not 4. Could this be issue? Any ideas.
This is snapdragon
G935UOYM4BQD2 this is unlocked firmware

You are correct. There is an 8 version on the U firmware that will work though
Any idea where I can find the u version?
Found it on Sam mobile. Thanks
Is there a place to download this firmware without paying?
I found version 8 935u firmware. Used odin correctly. It flashed and said passed in green. Kept rebooting to samsung power on screen. What am I doing wrong?
You need to download and flash the SM-935U 8.0 firmware that matches your baseband version exactly if you scroll down you will see an USA(AT&T) version that matches your baseband that is the one you need.

So just to clarify. My baseband is G935AUCS8CRJ2 can I flash this Unlocked firmware? G935UUEU8CRJ2
If so, do I use all of the parts in Odin, or just AP?
