[SOLVED]IMEI Null , Unknown Baseband - (*update) and recover IMEI

[SOLVED] [temp. fix] IMEI Null , Unknown Baseband
Confirmed working with i337 and i337m
Original problem:
Hi
I have received an i337 s4 with imei nul/nul and with no baseband (unknown) - see attached pics.
The user stated that he played with some menu from Samsung secret codes.
It's on stock recovery, download mode doesn't show any flash counters, binary and sys status as 'official' and write protection 'enabled'
Also the home screen shows a certain menu with a notification 'update device information' see attached pic.
I have done a factory rest via stock recovery, still showing the same issues.
How can I solve this hopefully?
update SOLVED:
Thanks to Colonel Sander aka Quasimodem for all the help, here and over hangout.
After having problems with QPST/ EFS pro etc, in repairing, I flashed his efs.img , this removed the home screen error notice and the phone was working normal - still with IMEI = null / null and baseband = unknown
Today he made a flashable zip, which helped me fully flash his efs,
package_extract_file("flash_image", "/tmp/flash_image");
set_perm(0, 0, 0777, "/tmp/flash_image");
ui_print("Installing EFS...");
assert(package_extract_file("efs.img", "/tmp/efs.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p10", "/tmp/efs.img"),
assert(package_extract_file("m9kefs1.img", "/tmp/m9kefs1.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p13", "/tmp/m9kefs1.img"),
assert(package_extract_file("m9kefs2.img", "/tmp/m9kefs2.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p14", "/tmp/m9kefs2.img"),
assert(package_extract_file("m9kefs3.img", "/tmp/m9kefs3.img"),
run_program("/tmp/flash_image", "/dev/block/mmcblk0p15", "/tmp/m9kefs3.img"),
delete("/tmp/efs.img"));
delete("/tmp/m9kefs1.img"));
delete("/tmp/m9kefs2.img"));
delete("/tmp/m9kefs3.img"));
delete("/tmp/flash_image");
After the flash I got back my baseband :victory:
My IMEI has changed from null / null to a 0 / 00 this is not a problem over here, and my network is fully active and amazingly still UNLOCKED.
I would hopefully inject my original IMEI with Z3X box service if I couldn't repair over the QPST and other similar softwares.
Thanks all.
UPDATE:
I have added the EFS zip, this works confirm with i337 and i337m
But this does NOT work with i9505 (I would not advice to flash it on i9500)
Follow all the procedures before going for a flash.
Thanks to @Quasimodem for the original zip.
UPDATE Feb 24 2014: HOW TO RECOVER IMEI
Unfortunately I do not have the phone myself now, but here is success report of recoveing IMEI after flashing this EFS:
Ziida said:
Thanks! Flashing through TWRP didn't do it for me so I installed CWM tonight based on your suggestion and it's worked! My baseband became readable and my IMEI went from "null / null" to "0 / 00"
To anyone else coming into this thread: CWM was a bit of a hassle to install, so I had to use this guide (mind their typos...).
Anyhow, the most exciting part is after flashing the good Captain's EFS file my phone was recognized by QPST again!! I went ahead and flashed the AWS .qcn file from this thread, and now my IMEI number has returned!
I hope you have similar luck, dogmatism!

I have a backup of my EFS, it may be possible to Hex edit it, and change the IMEI to yours, then manually insert the EFS files with ADB or Terminal Emulator

Yes pm me your imei and I'll try to edit my efs files... I'll pm you an untouched copy too if you want to have a crack at it...

check pm.
I have also installed stock ROM. but it is as if nothing changed. :what:
I wonder if I should flash a custom recovery and format the system manually and then Odin flash the stock ROM.

That's not going to do anything for this particular issue. I'm about to zip up my backup and send it your way, and dig around inside the files myself. This is repairable somehow.

I will watch this for awhile, and see what happens. Just trying to figure out what you guys are trying to accomplish...carry on.
My suggestion is be careful with IMEI as if you let someone have your #, and at any point that person plugs in that # in his device and hits the network, you will get both devices blacklisted from the carrier. I am hoping you guys know this.

i have to first root then. give me some time.
I think you sent your efs via dropbox link, i have it downloaded already thanks.

[Q] IMEI null/null, baseband unknown, no EFS backup

Hello everyone;
I flashed BAM-Android on my Galaxy S4 i9505 yesterday (first flash) and the network was working very poorly, every 2 min I would lose the signal.
Therefore I flashed other AOSP and Custom roms, flashed other modems to test better options and this morning I noticed my IMEI was null/null and my baseband was "unknown".
I tried flashing a stock samsung rom twice but it didn't change either. I bought my phone on ebay so no warranty at all. I don't have a backup of my EFS partition.
After browsing through forums I didn't find any solution... Do you guys have any other idea ? Or have a efs.img in stock so I can flash it in my phone ?
Thanks a lot !

You cant flash other phones's imei on ur phone.No other option than service centre

Don't you have IMEI written on your box or receipt?
Using other phones's IMEI is kind of identity theft

Go to service center. Cant do anything. Or you could grab someones IMEI and null theirs. Having 2 phones with same IMEI is illegal and your carrier might penalize you.

No that won't work. Each phone has different partition structures. Efs is not the same in S2 as in S4. Btw you can't use efs from one S4 on another S4. Efs is unique for each phone (IMEI, wifi mac, serial number...)

[Q] IMEI null/null, No SIM card - unable to find fix

Hey, I started flashing custom ROMs to my S4 (GT-i9506) about three months ago and everything was okay, but just recently I tried to return to my stock i9506 4.4.2 ROM and i succeeded in doing so, but afterwards I noticed that my S4 wasn't recognising my SIM.
At first I assumed it was a faulty SIM card (my SIM had multiple scratches on it), so I bought a new SIM card and yet the problem persisted. I tried to make calls and etc but my phone retuned an error stating, "Mobile network not available". I decided to check my settings and I noticed that my Baseband Version was labelled as "unkown".
After seeing this I searched for solutions online and came upon S4 service codes, I used the "*#06#" code and it returned a message saying "IMEI... null/null". Yet again I searched for a solution and came upon none to help me
I soon found out that my problem had something to do with the EFS parition in my phone. I re-rooted and installed ES File Explorer and opened up my EFS folder. In her everything looked ordinary, but then I noticed that my .nv_data file was missing, which, if i remember correctly, is responsible for important functions such as the IMEI and Baseband
I tried every solution I could find online and nothing fixed my issue - I'm only writing this as it's the only option which doesn't require me to go to my local Samsung Experience Store.
TL;DR
My GT-i9506 doesn't know its own IMEI and Baseband version and I'm all out of solutions at this point.
Am I better off going to the Samsung Store?

IMEI no longer inhabits the EFS folder, so you're not missing anything. Flash the modem for your ROM again through Odin and see if that corrects the issue. If it does, use Wanam's EFS Backup to properly backup the hidden partitions where the IMEI is now stored.

Flash the latest stock lollipop rom for your device and you will be fine. Sounds to me you were on Lollipop stock and you downgraded to Kitkat.

Tried this too, but failed also

I don't know which of the hidden partitions the IMEI is stored in. I only know where it's not, and that's not in the EFS folder. However, based on the partition names, the IMEI is likely stored in any or all of the following partitions: m9kefs1, m9kefs2, m9kefs3. While unlikely, it could also be stored in the following partitions: modemst1, modemst2.

Hi, I used to use Optimus G, it has IMEI in m9efs* and Modem in modem, modemst*. I never had IMEI problems but on S4 it is really scary. Will backing up EFS in TWRP, manually dd'ing EFS, modemst*, m9kefs* block10 make me stay on safe side?

Just use Wanam's EFS Backup tool. It backs up all those partitions, so no need to run commands in a terminal.

Have you tried flashing stock with Odin?

Have you still got a radio signal (Make calls / text etc) ?
If not, you might have lost your EFS partition, which afaik, needs a professional repair to fix unless you backed up that partition first

Might be too late if the EFS partition is corrupted and you don't have an IMEI and can't make calls
There are a couple of threads kicking about on XDA S5 forums where people have managed to recover their phones with similar problems, have a read through the Q&A forum and see if you can find them, some fixed by flashing stock, not sure how that worked, but apparently it did
Read others saying they backed up a working S5 EFS and restored it to the broken one
Have a read and see what you can find

so you saying the only thing i can do is to flash a new imei with octoplus or some other kind of boxes.
and if i recover imei from other phone it will not cause network problem becuase there is two phones with the same imei ??

The law in most countries states that the only IMEI number you can use in your phone is the one it came with.....
Nobody here on XDA is going to give you advice on how to change your IMEI for that reason......it's against the law..... *and* as such, it's against XDA rules as well......

Hi!
Really need your help
I flashed my phone and sold it.

Today I checked the phone and saw, that no IMEI were present.
I restored the IMEI, but there is no network connection.

i use an A2017G stock
https://www.pic-upload.de/view-34346603/Screenshot_2017-11-22-11-27-05.jpg.html

I sometimes get problems just after flashing, and GSM/Wifi 5Ghz take up to 5 minutes to initialize. Deactivating and reactivating the sim card helps. Did u try that?
- Else, I'd get a 7.1.1 factory image and start over, that baseband is *exactly* the same as mine and I only have that "5-minutes-without-wifi-and-network" bug.
- Try looking for wifi just after booting the phone : if you only see 2.4Ghz networks and no 5Ghz network, just turn the sim car off and on, and it's ok, just that bug.

reflash a full stock firmware, if you have imei, you must have then, then if you want, do the process again to get twrp

Hi Folks,
i've done some reading and my problem is a broken EFS sector due to TWRP recovery.
Even after manual IMEI restore, the EFS is broken and causes the no service issue:
https://forum.xda-developers.com/axon-7/how-to/investigation-recovering-efs-twrp-t3522171
Only option is to get a EFS copy from another device, push it on my one and change the IMEI to my own manually.

If efs was ’restored’ using the signed twrp used for unlocking then there is no fix for that.
