Galaxy note 3 sm-n900 Unkonwn baseband

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 :

[Q] n900 stuck on Samsung logo

Hi guys I've been facing this problem for a few months now. Hope someone can help. I am on vn rom v14. While on this rom I had flashed the clear warranty zip to reset my knox counter to 0. I was curious to see if it would work. Therafter I decided to flash stock firmware. After the flash I was stuck at the boot logo. So then I booted into stock recovery and wiped data factory reset, wipe cache and wiped dalvik cache. The phone then boots up however it doesn't receive any network signal. It can only connect to wifi. Base brand version and imei are also lost. The only solution that I found was to flash the vn rom again and everything is fixed. I seem to be stuck on vn rom as this is the only rom that picks up signal. Tried many other roms and have the same problem. Eventually I have to return to vn rom to use my phone. Can somebody please help me.

After you flash your stock firmware (you lose your imei )
You should install this zip file from twrp or cwm

downgrade lollipop to kitkat 4.4.2

Hello. Today I installed on my notes 3 SM-N9005 lollipop 5.0 version Poland but I found them a few problems: the first is that the vibration of the keyboard does not work. I found two of the slowdowns in the task manager. Now if I want to return to kitkat I can do fleshando firmware via Odin? ??

+1
I asked the same question with no accurate answer, i found a thread on how to downgrade from leaked ver. Of lolipop and not the official one and i won't risk trying this method, what I'm asking for is it possible to downgrade to official kitkat using odin specially that i have ticked update bootloader button when i flashed official Lolipop.
Will this work or we are risking our mobiles for a brick?
Appreciate if someone answered us with a proven record.
Regards,

however I have seen videos on youtube that have made the downgrade from 4.4.2 to 4.3 fleshando only the firmaware dacendo and then wipe data / cache. I think the same procedure also applies to switch lollipop kitkat.

It's safe to downgrade using odin. I did it myself from the leaked and the official release (both of them with the bootloader updated). In case odin complains about size just check my last posts and use the PIT file I provided.

Hi,
I have downgraded from the Polish Lollipop without using a PIT file - successfully. You will need to carry out a data wipe and factory reset, but it worked fine.

I couldn't... flashing ENC2 with Odin gave me size error, flashing with PIT solved that, but my IMEI and Baseband were gone. I gave up at that point, flashed Lolipop again and am back to normal now.

Download N9005XXUGNK2 from sammobile and flash with odin, after the flash complete do a factory reset via recovery or your phone wont boot and will be stucked in samsung logo

No imei

I updated my galaxy s4 i9500 to 5.0.1 using odin. My phone was working well when I saw that i am having no more root access So i rooted my device. But rooting on 5.0.1 was no use. Most of the application's were not compatible with 5.0.1. So i flashed xposed framework and was dumb enough to read the full instructions. After flashing my phone was soft brick. So i went to the forum again and saw the instructions that thr version is not for Touchwiz. So i glashed cm11 and it worked my phone was working again but i noticed that it's been a while and my network signals are not appearing. I thought that the zip file would be corrupted so i flashed ozcan rom. But no success. Then i opened my settings and saw that imei was "Null/Null". And lastly /device/data folder is empty. Would be great if anyone will help.

1. Flash again the lollipop version.
2. Then root it using cf root.
3. Problem solved
ps maybe you should also do a factory reset, but backup first.

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.
