MG9 to MG5 firmware, losing imei

Hi there,
I'm just wondering why my phone is losing its imei (or rather, its changing to the generic 0049xxx) after flashing the latest MG5 firmwares (I tried three different versions now). I first came from MG1, then flashed the MG9 when it came out. Now, when I flash any other firmware, my imei gets f'ed up.
I havent rooted my phone yet, I'm just flashing firmwares I downloaded from sammobile. Is it just because of this MG5 firmwares not being compatible? Will I still be able to flash newer firmwares when it goes out?
Thanks in advance, cheers!

I have downloaded the August version for the united arab emirates , it seems to see my imei , but whenever i lock the phone (or screen idle closes the display) 90% of times phone freezes and I need to restart it.

it seems that in the latest roms samsung(for S3,S4) change the efs structure ... thats why imei gets mess if you try to change rom after.but if you change the modem with old one it may works....

Gotcha thanks!

i have the similar problem .
updated from G1 to G5 via samobile,
same problem ... no network registration
..
since i was rooted i used cutsom rom legend and crash . working fine for the moment \
but i need to solve this issue if i want go on stock
BTW i have some EFS back up folder can it help in recovering the IMEI issue

who flashed the MG9 firmware had their EFS partition modified.
So in case if you have to go back to earlier firmware you will have problems with IMEI. You have to:
- Restore EFS (that is backed up before this change) or
- Flash MG9 modem which can still read the modified EFS.

Flashing or restoring efs backup doesnt work after flashing mg9.
You need to return to your firmware when you first get your phone out of the box with clean install and wiping everything in cwm before getting into download mode.
Then after flashing the firmware, root then restore efs backup.

so what is new
once you flashed the MG9, the efs partition format has been changed, so if you downgrade (regardless if to the original stock) you must restore the efs partition from the backup you made or just flash MG9 modem.

May be your imei data was corrupt.
Did you make backup for the EFS data?
If so just restore it.

i have the same issue with a friends phone, no EFS backup, he won't tell what he did to the phone but now imei is null/null and doesn't have a baseband, anyway to fix it?

similar problem
I have a sm-n900 exynos and I have lost my imei and baseband during a Samsung flash. I have a TWRP backup, efs.img backup by dr.ketan's backup tool but nothing is able to restore my efs. I have scanned emmc blocks for bricked blocks and all blocks come back as non-corrupted. may be the partition is corrupted .how do I erase my efs partition to rebuild it. I have tired to flash PIT from ODIN but that too doesn't work.
tried this post http://forum.xda-developers.com/showthread.php?t=2567133&page=36
but need a guide to identify the partitions and how to rebuild them. by any chance anyone know if I could extract twrp backup to files to restore efs or from efs.img so I can use the nv_data.bin, since tried restoring the backups and it didn't restore I feel the partition might be corrupt and hence not being re-written. so might be I have to rebuild the partitions by formatting as explained in this thread. but I don't know exactly the steps for exynos variant. I tried using terminal on twrp but mkef2 command shows mmbcblkp03 doesn't exist which as I have read in posts is the efs partition on this phone and reboots to twrp recovery. and mmbcblkp12 show filesystem too small and reboots to twrp recovery

weird thing is, i sometimes find the imei and the baseband and sometimes i dont, phone's not rooted yet, trying to find a way to root it without trippong knox since is not mine, but maybe im able to recover the efs i hope it works

Same problem here...
Hey guys, I'm experiencing the same problem since i installed VN kit kat rom. I searched for the efs backup and i found it but when i use odin to flash it it doesn't work. I tried flashing back to stock but that doesn't work. Can soneone please help me?

HI just one question my friend has the exact same problem (IMEI null/null) baseband is unkown !!! the device is SM-N900 running 4.4.2 right now he flashed the file but the problem still exist !!! pleeeeeeeeease help !!
this file only works if the device is running official 4.3 ??? or we can flash it on stock 4.4.2 !!!
it seems wiered to me that others on this forum flashed the file and it worked with them !!!!!
pleeeeeeease help

You can still flash it if you have 4.4.2. The file i uploaded to be flashed is just to flash the baseband not the rom itself.
Btw did you flash the file with cwm recovery?

That s due to a modem you update so go back to original modem. ..

Ohw ok.... When i flashed the file my sim card got the read the first time i restarted my phone. I don't get why it doesn't work for your friend. What you can try to do is to download (google) other basebands for n900 and try to see if those work (it doesn't necessarily have to be 4.4.2 cuz i flashed the same 4.3 file on my 4.4.2 phone and it worked). If that doesn't work you can try to flash a stock rom and then flash a baseband ( while still in recovery mode), try the one i uploaded. just be sure to have a backup of the current rom if the stock one doesn't seem to be solution.

Actually it IS possible for the n900, the knox reset also let's users downgrade if they so choose to.. But he doesn't need to downgrade, he lost his efs/imei and that can be fixed if he made a backup or by using the other options that I listed.

Do not try to recover EFS...
It is not the problem, the problem is that you have unknown baseband (Modem damage)... Please check if it can mount /EFS folder (Check in recovery)
It it fails to mount /EFS, then you will probally need to find someone with a Asansam box to fix it...
Remember to backup you EFS folder

IMEI null/null comes from modem failure. It is not because your EFS is wiped, if your EFS was wiped, then you would get a generic IMEI number 0044.....
But try to go to recovery, do you get "failed to mount /EFS"
But your IMEI null/null could also be a hw failure...
But I would try to flash a 4 part 4.4.2 firmware
Remember to backup your EFS, it is not corrupted...

Original CSC is INU. But showing other CSC is THL (wrong). Modem is blank. SW Version is unknown. My guess is modem and csc related issue. I have tried flash modem, but not affected. CSC also not affected. Why this happen?

Note 3 SM-N900 IMEI null Baseband unknown

Note 3 SM-N900 IMEI null Baseband unknown
Android 5.0
Firmware N900XXUEBOE3_N900ODDEBOB2_N900DDUEBOB1 (India)
How did the problem start? – my kid was playing some game in the phone and when I got it back I noticed the problem. It wasn’t because of flashing custom ROM or rooting. It could be due to firmware upgrade as upgrading was set on automatic but not sure.
What all have I done to solve the problem?
1. Rooted the phone and checked EFS folder. The EFS folder did not have .nv_data.bak file. And I don’t have backup of pre-problem EFS folder.
2. Downloaded stock firmware, extracted the modem file (bin) and flashed it, both with odin and cwm. Didn’t help.
3. Downloaded and flashed with odin stock firmware Android 4.4.2 N900XXUENI1_N900ODDENF1_N900DDUENG1_HOME.tar.md5 AND also N900XXUENG1_N900ODDENF1_INU. Didn’t help.
4. With each of the above stock firmware I flashed the following modem files:-
(1) N900_XXUDNA1_MODEM_CWM
(2) N900_XXUENE1_MODEM_CWM
(3) N900_XXUENF2_MODEM_CWM
(4) N900_XXUENG1_MODEM
(5) N900_XXUBMI2_MODEM_CWM
Didn’t work.
5. Used EFS Tool Samsung N7100 900 to back up EFS folder of a working Note 3 SM-N900 and restored the backedup folder to my phone – didn’t work.
6. Tried GSII_Repair app (both with my own EFS folder and my friends EFS folder. – didn’t work.
7. Tried to install xposed to use imei changer app. But xposed did not install as it is not yet compatible with Android SDK version 21 or processor architecture armeabi-v7a.
8. Tried Kies firmware upgrade and initialization, SM-N900 does not support initialization.
9. Tried secret code and got to Service Mode. But service mode is like a blank page of a lined book – no options shown.
10. And I tried factory reset with each of the above firmwares. Did Factory reset and wipe cache partition before flashing new firmware – didn’t work. Then tried it after flashing – didn’t work.
11. Also tried *#197328640# or *#*#197328640#*#* both didn’t work.
12. Tried fix mentioned in - http://forum.xda-developers.com/showthread.php?t=2507403
13. used advice in http://forum.xda-developers.com/showpost.php?p=52408318&postcount=87. now my phone is running Android 4.3 but imei null and baseband version unknown persists.
Can’t afford a new phone. Could somebody please help? And I hate 13 of anything,

I'll do as you suggest but I have a question. Once I delete dev/block/mmcblk0p3 won't I need to replace it with an uncorrupted file? Doesn't the phone need dev/block/mmcblk0p3 for it to work?

It should be regenerated after reboot, assuming the block has corrupted and unable to write the efs/imei. I'm not sure if it should be the same for N900.
The guide is for old firmware and for N9005. If efs block isn't the issue, it won't work then. It worked for a very few people though. If you have nothing else to try ....
There is also a thread by mirek on solving softbrick/imei issue just a few topics away.

WIPED IMEI without a BACKUP

Hey, guys, I have a question: I HEARD that the original IMEI of the Note 4 (I have the N910C - TCE) is read from the motherboard, but I also heard that if you don't have a backup of your /efs folder from the original stock ROM then you're screwed?
Do anyone of you all know anything about this? Problem is: I flashed a ROM on my phone and it wiped my IMEI, replacing it with a generic IMEI (350050500009692), and now I can't get it back without a backup of the /EFS folder?
I would REALLY appreciate your guys' help as its been at least a week and a half since I lost network service... if you guys need more screenshots, just ask and I'll post them.

Flash stock rom with odine wipe everything using a pit file...
I hope that will resolve your problem.

My friend have done the same thing. I flashed stock ROM from sammobile with Odin and IMEI was back and network service was back.
http://www.sammobile.com/firmwares/database/SM-N910C/

@webmaster750, should it be my phone-specific firmware or just a stock firmware (regardless of region)? Thank you for the reassurance, man.

Okay, thank you! I already tried to flash another region on 5.1.1 with and without the .pit file, but it would not fix the problem, so do you think I need to flash my firmware for my specific serial number? Like the firmware that would be downloaded from Kies or Samsung Smart Switch?

yep:good:
Make a current efs backup before...

Okay, but why make a EFS backup before when my IMEI is all screwed up?

vince.lupe said:
@webmaster750, should it be my phone-specific firmware or just a stock firmware (regardless of region)? Thank you for the reassurance, man.

Yes, specific for Your country or/and provider.
In my friend case I download and flashed the 5.1.1. CROATIA(VIP) firmware.

Make it the same thing if you can make call if not you should not need it.

Thank you, you guys ☺ Okay, let me get this straight: so, I'm going to flash my firmware for my phone's specific serial number (more specific than my own region) through Odin when available and enable "nand erase all" with my specific .pit file as well? With no backup of my EFS (cannot make a call at all)?

Unfortunately bro you will not get anything, l know my words very disappointing but efs or serial number is special information stored in your phone (emmc)by special partition and if you wiped that ,then you lost your serial number forever,
You have only two way?
1-go to Samsung service and they will repair your phone and will back your stock serial number but that will cost you much money (200) $ or more :crying::crying:
2-anyone with zx3 box or octopus box will fix it but another serial number you will get
Super imei and that will 50$or less

@medo sator, two questions:
1. How do I know if my emmc partition is ruined? What if it's just my EFS folders?
2. What is Super IMEI like you mentioned in your comment above?

I have the same IMEI problem and have used odin and samsung tools pro with no change, also i tried reseting efs and nothing. It's a model SM-G750A galaxy mega 2 and i'm out of ideas or exhausted every search, what can i do?
Thanks,

Ok first install https://www.androidfilehost.com/?fid=24459283995315430 that is MM stock rom for N910C. In odin under options please check auto reboot, reparation, f. reset time, nand erase all, phone efs clear and phone bootloader update. Just in case it asks for the pit click on the pit tab and select the N910C pit you can extract in this firmware. I posted the pit as an attachment just encase you can not figure out how to get the pit file.

Will this work for my sm-g750a galaxy mega 2 also?
