replace XXXimeiXXX with your IMEI number
To find the IMEI number:
From the Dialler, enter *#06#
Hello
Keeping this short
1- Unknown Baseband/IMEI
2- all codes "*#06#" ... etc , doesn't work " no network"
3- DM mode works
4- G900V Verizon rooted, 4.4.4 firmware.
5- EFS file corrupted, no NV_DATA at all " I'm not sure if s5 got one ".
6- Don't have EFS backup, Or, similar device to try an EFS img backup.
I've tried some of the solutions here that I found relevant, but nothing worked in my case.
Any suggestions ??? Srvc want's to change the board "200$" and not bother to retrive IMEI
Thanks
Finger printer sensor version reads: null
Also on stock recovery: dm-verity verification failed
I think the issue started because I had another n910t phone, I made an ndroid backup of it it with twrp. I then flashed twrp, the same ROM( [ROM][5.1.1][DOK2]N5 Express 3.4D[Feb-21-16][N910T][N910W8][N910T3]), then did a ndroid restore on this new n910t phone and now finger print says null. I registered a finger print on the old phone, no private mode. I never registered one on the new phone or enabled private mode.
I tried a Kies/Smart Switch emergency recovery but no luck.
Any ideas? Possible to downgrade to 5.0.1, then do a Smartswitch emergency recovery?
Found a solution if anyone ever stumbles across this thread.
How it happened:
I did a full Twrp backup, including EFS on a n910T. I received a replacement n910t. I thought I could restore the twrp backup from the old straight to the new n910t. I was wrong. EFS is device depending and contains the individual phone info like imei,S/N,etc. Basically my new phone took characteristics of the old one and the EFS became corrupted. My fingerprint sensor didn't work and I had the "dm-vertiy verification failed. If the dm-verity fails, finger print sensor won't work.
How I repaired my EFS, or what I did to get it to work. Your mileage may vary.
All of this on stock rom: I got the stock from by using smart-switch and doing emergency recovery, entering my model number and serial number. I then cf rooted and flashed twrp using odin.
1. I check to make sure my IMEI and S/N numbers stored in the phone (about device) matched the sticker on the back. My IMEI matched but my S/N did not. My S/N was from my old phone, big whoops!
2. I corrected my S/N by editing the serial number file found under your EFS folder. You need root access to edit it. I use room toolbox lite, root browser to edit it.
3. Because my EFS became corrupted, my phone was in limp mode, eg it was slow and lagging, it was stuck in "factory mode".
4. I took the phone out of factory mode. Again you need root access and root browser. Go to EFS folder/factoryapp/factorymode and edit the file. Change it to off. Also go to efs folder/factoryapp/keystry and turn it off also. Reboot.
5. I entered this command:
mke2fs /dev/block/mmcblk0p13 (for N910G Note 4)
mkdir /efs
mount -t ext4 /dev/block/mmcblk0p13 /efs
6. Do a factory reset, reboot system
7. I then did a stock firmware flash again with smart-switch. Everything works again now. This time I will make sure I back up my efs but don't try to restore it.
Maybe this will help someone in the future.

ok, and the last thing, I can change the imei of the device with the box z3, because unfortunately I had my device with the imei changed without knowing it, so I updated my device from mm at oreo it and changed my imei and now I have no signal, so I would like to patch the certificate that I had before, since you can not do dowgrade
the imei is written on the back cover.you must write that imei.i am not sure if it works with another imei
