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!

updated from G1 to G5 via samobile,
same problem ... no network registration
..

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.

HUGE problem with imei. please help

i didn't have an imei on my i9500 for some reason so i flashed a leaked 5.0.1 rom on my i9500 which fixed my imei issue. everything was working (calls etc). since you can't flash gapps on this rom for some reason i switched back to a stock rom and saw that my imei and baseband version were gone again. after some digging i found out that this was an efs file issue, so after (literally) 16 hours i finally fixed it by flashing the 5.0.1 leak with philz touch, backing up my efs file, and flashing a custom rom (hassan rom v7) and my imei appeared again. i wanted to go back to stock 4.4.2 touchwiz so i tried to flash it again but it gave me a fail. and when i tried again it succeeded but my imei was gone again after some more digging a found out that the 5.0.1 was a chinese rom and changed my model name to i9500chn, and they imei worked only when that was my model name.
so now i'm kinda stuck on hassan rom and my phones model is i9500chn. even though i backup my efs folder successfully, if i flash another rom that changes my phone to i9500 it removes my imei and the efs backups won't help (restore is successful but doesn't work).
what can i do in this situation??
PLEASE XDA PEOPLE HELP ME.
anyone???????
please?!
Wasn't there a tool to backup IMEI number? I remember there was something similar for the Galaxy Ace.

Efs got corrupt after flashing 5.0.1 leaked Chinese rom. How to restore it??

HI Devs,
I have flashed leaked lollipop build on my Samsung Galaxy S4 I9500, evrything was working fine, later I decided to go back to stock 4.4.2 rom.
When I flashed stock rom, my phones' efs folder got corrupt, now my phones baseband is unknown, Serial no. is something different, Imei no. is something different.
I tried flashing back that leaked build, again everything started working fine. So I backed up efs folder from there and again flashed stock rom via odin.
After flashing stock 4.4.2, again same issue was there, so i restored the Efs folder and restarted my S4.
But nothing changed.
Can anyone help me in restoring efs back to back.
I want to restore my phone to stock build and with original imei and serial no.

Hi mate
Looks like the problem is the modem and not the efs , try flashing a 4.4.2 modem
There are several people who have the same issue. I don't know if there is a solution. I haven't seen one on this forum. Try google.
You can't downgrade. Once you are on 5.0 then you stay on 5.0

Null IMEI after flashing with Odin

My S4 GT-I9500 was upgraded to lollipop 5.0.1 by the service centre guys and it's not supported by my official android policy.
So after googling a lot i found out a you tube vdo for downgrading lollipop 5.0 to kitkat 4.4.2 on S5 and as shown i did the exact steps i.e. downloaded firware from SAMFIRM & used ODIn to flash it and the entire process went fine, no errors.
But after booting up there is no mobile network connectivity and IMEI number is unknown , IMEI SV is unknown.
Is it possible to make the phone working again, any help would be greatly appreciated.

Hello sumanjit,
I faced this problem today! i was on Lollipop and then tried to downgrade it to Kitkat but that erased my IMEI number. To get it back I again flashed the stock 5.0.1 Firmware. And for downgrading it have a look at this - http://forum.xda-developers.com/galaxy-s4/general/i9500-easy-to-downgrade-official-t3036258 . You need to be rooted on 5.0.1 with a custom recovery.
All the best!

I had Philz Touch recovery. In it select- Wipe data reset.
Then you will be asked to - 1) wipe data reset
2) wipe clean install (something like this).
So select the clean install option.
Boot to download and flash the firmware.
Note: I tried the same and got my IMEI nulled. And I was suggested to follow the same procedure as displayed in that post. I haven't tested the yet. I am still to restore the EFS partition and will report back with any probable solution.
If helped press thanks!
All the best!

Sorry, i got a little confused with the last paragraph. Did you face the IMEI nulled issue even after doing Philz Touch recovery?

Yes my IMEI was nulled. The main problem is the new Lollipop bootloader. But many members claimed here : http://forum.xda-developers.com/galaxy-s4/general/i9500-easy-to-downgrade-official-t3036258 that after following the exact steps they successfully downgraded to KitKat. Now I have XXUFN12 firmware so I am still downloading UUBGNJ1 to check whether it works.
All the best!

Baseband & IMEI unknown after flashing CM14 on SM-N910C

A few nights ago, I flashed CM14 with Nougat on my SM-N910C. Unfortunately, ever since the flash finished, my phone stopped reading any SIM cards. The baseband and IMEI both read "unknown" in the settings. Is there any way to return these? I'm okay with anything as long as it ends up making my phone usable again.
I'm not an expert at this, so please explain stuff your help is appreciated, thanks!
Bump! Please help me out!! Any tips appreciated

Did you made efs backup from twrp before flashing rom ?
If you have efs back up then restore it.
If not then Try flash stock 6.0.1 firmware via odin and do factory reset from stock recovery after flash.
