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.

[Q] IMEI lost ater installing a custom kernel

Hello guys i've installed merruk kernel 2.0 pre-final and my imei is blank. It don't recognize my sim card. I've made a full backup in CWM but it not worked. I want to revert ext4.zip process and install my stock kernel that i have a backup, is't possible? Will it restore my IMEI?

most likely the ril is not compatible with your baseband
I keep saying you cant use an old kernel with a new firmware baseband or you will loose imei
you can solve this by replacing the ril lib with an old baseband version
see
http://forum.xda-developers.com/showpost.php?p=52449987&postcount=232
try the hyp 8 ril - you can try others if you wish
if you want to return to stock you will have to flash stock rom via odin to convert your system from ext back to rfs
see
http://forum.xda-developers.com/showthread.php?t=2568853
you can then restore your stock nandroid backup as long as you restore it using the kernel and cwm from which it was made on

My current ROM is the stock rom of S5360B, how do i do it without brick my phone in this case? what other methods should i try to restore my IMEI if this method not work?
Current ROM info:
Model: GT-S5360B
Version: Android 2.3.6
Product Code: ZTO
PDA: S5360BUTME2
CSC: S5360BZTOMJ1
MODEM: S5360BUTNA1

The GT-S5360B is exactly the same phone as a normal GT-S5360. It will work without much problems (if any), and it most probably won't brick your phone. Flash the zip for your baseband as per nornal (remember to mount /system)
Any other methods? I'm not too sure, apart from using Galaxy Toolbox to check your efs partition is damaged and backing up your efs partition.

no difference - you can flash 5360 on a 5360b if you want to
the only difference is the B version is branded varient of the 5360
you can use any file you like from the 5360 without any problems plus if you really want the 5360b firmware to flash stock rom via odin at a later date its also on my firmware thread

Ok, I'll try to install the stock rom via odin, hope it works . I have a doubt, I ran the ext4 converter. have i to follow this tutorial http://forum.xda-developers.com/showthread.php?t=2007720 or can i install without re-partition?
If it not working, what ril fix file can i use for my phone?
I'll update the result here.

Never tick repartition in odin
all you have to do is flash pda modem and csc - DO NOT tick anything extra
your phone will convert back to rfs from ext if you flash stock rom via odiin
I posted a load of rils from different basebands in post #2 of this thread - you can use what ever one you want - ril is dependant on rom firmware and kernel being used

The phone doesn't recognized in download mode. It says "unknown device". I've installed Saumsung drivers and it's usb work fine but in download mode it not working.

then click unknown device
update driver
select folder
select the install location of the samsung divers (normally C:\Program Files\SAMSUNG)
if its not there then you havent installed the drivers
note - you do not need drivers for mass storage mode - you only need them for adb (download mode)

It worked! I've installed the stock rom and my IMEI is showing and the sim card is ok. Thank you all. But i have one more question:
I don't intend to continue with stock rom and stock kernel. What should i do to prevent this error occur by installing any custom rom or custom kernel? I've heard that i have to backup the efs, but the efs folder is always blank on galaxy y.

the efs partition is empty on galaxy y because that partition is not mounted
you can backup your efs partition with galaxy toolbox but that wont help you with the problem you had
I keep saying its to do with the ril - you cant use an old kernel with a new firmware and vise versa
to solve this if you use an old kernel with a new firmware replace the ril lib of the new firmware with one from an old firmware
Iv even posted them

Which Note 3 model do you have?

Thanks for the replay.
I have n9005 32gb and i fix the problem.
What I have find out that if u flash higher version of baseband u need to flash the same version that u had and not the base line.
At first I had the following rom:
9005XXUEND3_N9005OLBENC3_N9005XXUENC2_HOME
After a few weeks I flashed the following rom:
N9005DXUENE4_N9005OLCENE5_N9005DXUENE3_HOME
Yestarday I have tried to flash the following rom:
N9005ZHUENE6_N9005ZZHENE6_N9005ZHUENE6_HOME - it stuck in the end with ext4 image faliure.
I have tried to flash the first rom (the base line) 9005XXUEND3_N9005OLBENC3_N9005XXUENC2_HOME and the baseband was unknown, and when i flashed N9005DXUENE4_N9005OLCENE5_N9005DXUENE3_HOME, it fix the problem.

[Q] Galaxy note 3 sm-n900 repair imei without efs backup

Hello everybody, I have a galaxy note 3 sm-n900 and I have flashed another rom on my phone ,
but what I have got is null imei and I don't have any backup for efs file
I have tried to flash a stock rom but still have the same problem.

There is no simple way to enter the IMEI manually.
After flashing stock rom, try to reflash the modem (baseband) 1 or 2 times more.
Does the baseband stick after flashing? Check the Baseband Version with Phone INFO ★Samsung★ app (under FIRMWARE INFO section).

As you can see in the screenshots, your baseband is null so you have to flash the modem or the stock firmware again.
The screenshot shows your original CSC is KSA (Saudi Arabia). Try to download this stock firmware and flash again.
Open Phone INFO ★Samsung★ app > Menu > 'Firmware Browser' > enter KSA into the CSC textbox > tap Go button to search for the firmware.

The problem now is that your baseband is NULL, so you must reflash a vaild baseband.

2. should I try to clear EFS with odin ( when try to flash modem).
3. should I try a custom rom that make sense for this kind of problems ( help to choose !!!).
4. should I apply an update a zip file from CWM mode ( which file should I Use)
5. Is there any ADB command that can batch my IMEI.
6. Is it useful to take EFS backup from another note 3 sm-n900 (what I have to do after that).
I feel so lost, I need a help PROFESSIONAL

[Q] Imei Null on i9505 , Help?

Hello everybody i have imei null on my S4 i9505 , and im wondering if anyone has a efs backup for 4.4.2 ?

An EFS backup won't help as the IMEI isn't stored there any longer. IMEI is stored in the partitions used for the modem, so if you attempted an upgrade to 5.0.1 and got the IMEI issue, reinstall the original modem.
