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.

hello Guys, i have a galaxy note 3 sm-n900 on my hand right now, the problem is that i have no data, unknown baseband and no imei (Null/Null)......is there any solution ??? thank you...
In normal case all this missing comes from factory, if you need help from others you must explain how this happened, what rom you are using etc etc

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?
Fixed it!!!
If you have a n900 and your imei is null and your baseband is unknown all you have to do is to flash the file beneath with cwm recovery and voila!

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.
Maybe start with these :

If you don't know what you are doing my advice would be to
go to http://SamMobile.com and download the official kitkat
4.4.2 SM-900 firmware and flash it using Odin.
Be sure to do a full wipe including system, data, cache, dalvik
and last but not least a factory reset in twrp or cwm recovery
before you start the odin flash.
You will need to re-root your phone afterwards and install twrp
or cwm recovery. This is the surest way to resolve your network
and other issues.
This will give you a fresh clean start.
This will solve it.
Do you have twrp or cwm backup.
if not reflash VN rom 14.1 and you should get it back. secondly you can flash the modem attached.
1. wipe the device including internal memory in the twrp memory. put the phone in download mode. flash the modem via cwm rcovery
2. go back to recovery do just a factory reset.
3 now get any 4.4.2 stock rom for your region from sammobile and flash it using odin.
when the phone is rebooting and you see the Samsung logo pull the battery. put the battery back, go back to recovery do a factory reset. then let the boot complete.
it should be fine.
if it help don't forget to press thanks

sorry didn't understand you I was answering the op.
if you flashed vn rom earlier you should just do it again. just make sure you do a factory reset , and dalvik wipe.
If you need further help just look in the vn-rom thread for flashing procedure. anyway

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!

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.
