Hi.
I have Note5 at&t and it has Bootloader.
When I was trying to flash another stock at&t firmware, I've lost my IMEI number. As I learned, in order to get back my IMEI, I have to flash my old firmware, but I didn't memorize my old firmware name. And because of the bootloader, there is no way to learn old firmware's name with the root access. I can't root my device. Is there any solution?
Thank y'all in advance.
hi, i have the same problem, tried to downgrade to marshmallow but got an error, i flashed stock AT&T nougat firmware and now have no imei info or baseband info, i have tried flashing n920aucu4eqk6 and n920aucu4eql1 which are the 2 latest firmware versions but still having same problem...help! please
in case this helps anyone, i managed to solve my issue, i downgraded firmware to a 5.1.1 combination firmware, where the baseband and the imei were still being picked up by the phone, then i reflashed the phone with PK1 marshmallow rom (except i did not flash the CP file), only flashing the BL, AP and CSC files and now the phone is running marshmallow and picking up the imei and baseband information and can make calls and send text and picture messages.
thank you

hi guys, i want to ask something, i am having serious issue here! my phone was running android 4.1.2 but having no imei and unknown baseband. some thread stating if i was downgrading my fw, i will be having lost imei and unknown baseband issue, but in my case, the only fw that working was just android 4.1.2, and in my country, my phone was supposedly running on android 4.3. but when i am trying to install stock fw, i got a bootloop state. i have tried different method as such using xperifirm to download stock fw and updated fw, using pcc, but still suck in bootloop.
and my another question was, when i tried to relock my bl, flashtool showing different imei for my phone.
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

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.

Hi,
Thanks for reply . i have done both still IMEI is 000000000000.
Bump
Any help will be highly appriciated
Believe you can't do anything about it, if you don't have an EFS backup, you can't "recover" the IMEI, Serial #, etc. You can probably use this and change the IMEI to a screenshot of your own IMEI, but I am not entirely sure if it works or not.
Hope this might help.
I'm using a Galaxy M20 (m205f). Trying to root it, I somehow messed up the radio and efs partitions. Tried to install the latest stock Rom and it updated the binary from U4 to U7 with a null IMEI and unknown baseband. The IMEI repair softwares need the modem and the modem version presently is of U7 binary which is pretty recent and no IMEI repair tool supports this modem version yet. Is there any way I can downgrade the modem? There's no lower Android version and no combination file for the U7 binary on the internet so I'm stuck. Can I somehow put an older CP/Modem (from lower binaries) and make it work with the latest firmware?
