well i manage to bring back sound and baseband by flashing australian firmware and doing some modem flash over it
after that i tried couple of old roms but still imei remains "/01"
now i flashed back the australian firmware, this time didnt have to flash modem to brig back sound as it booted up normally
but still im struggling to fix my imei number as now i have a wifi phablet instead of working phone??
is it possible to fix the imei number somehow...this whole thing is driving me crazy!!!
Follow this link http://forum.xda-developers.com/showthread.php?t=2567133
Same thing happen to me. U cant bring back ur Ime flashing some roms or firmware. Because Now your EFS is blocked by KNOX. After you upgrade Do not downgrade or flash older modems .
This is the method you can bring back your phone. Before try this method flash the lates firmware then try these commands.
Good luck
Hi guys,
i was the last few days here in this Forum and tried to educate myselfe about flashing and Roms and all that stuff. But to be honest it seems that this problem is beyond everything i can handle. I really hope you guys can help me.
My plan was that i flash a clean (bloatweare free) ROM on my new (secondhand) Note 4. At first i tried the unofficial CM 13 (http://forum.xda-developers.com/note-4/snapdragon-dev/unofficial-cm13-0-910f-g-t3243386) mod. Everything was fine until i recognized that i dont have wifi. All i got was a weird WLAN-MAC (02.00.00.00.00.00). I just coudlnt enable my WIFI.
(ROM-Flashing with odin (3.09) and TWRP Indian Version (twrp-3.0.2-0-trltedt.img.tar)
I just thought its maybe the ROM which just doesnt fit to my mobile, so i tried the official nightly version from the CM Site Version 12.1 (https://download.cyanogenmod.org/?device=trltexx) But no success with that one either. The same problem. At that point i was pretty clueless about whats happening here and i started to panic a little. I was searching a few days about the WIFI Problem but coudltn find any solution. There was a Nexus-thread with the same problem but they didnt find a solution either.
At this point i was pretty sure that i messed up my mobile but i didnt give up.
I found the Nameless Rom (5.1.1.) here in this Forum and i tried it. The flashing was without any problems... and i was really happy that the first setup asked my about my wifi...until i recognized that this time the problem was that my Note4 couldnt find my SIM. Its really crazy
I tried everything. I tried to flash it again with different bootloaders and modems (from the ROM-Thread) and then i recognized that this time my SIM works but my WIFI wasnt there anymore. I dont know what to do anymore.

Please help me. I dont know what to do anymore :/ I am a noob, so please forgive me if i missed to give you important information. If you give me advice i will give you any information you need about my mobile!
Thanks for your help!
This is a really weird issue. I have never heard of this before. Try flashing the stock ROM with ODIN.
Good luck.
Thank you for you replay. I was thinking the same and read a little about it.
I have downloaded SamFirm and tried to download the correct firmware for my mobile. But unfortunatly thats not so easy as i thought.
MY modelnumber is SM-N910G. Since my mobile is manufactured in Thailand i assume that the software needs the region code from this country but i cant find the right one. Is Thailand even the right one?
Based on the pictures attached in the orignal post can you maybe help me to find out which code is the correct one?!
if someone finds this thread and has the same problem: I solved it by installing Dr.Ketan's ROM
I've flashed 139-63 stock rom and after that, fingerprint and both sim's are not detected by the OS. No network (wifi works), no fingerprint.
Tried many roms, still no luck. Is there any one who experienced this problem and fixed it? Please help me. :crying:
Likely need to flash ROM/firmware specific to your model number. Maybe someone here can post it if you provide model
i am also facing this problem i have also tried many firmware which say its for moto g4 plus xt1643 huh but non of them works then i restore my backup now and phone is working but still no fingerprint because its says it is moto g4 in model number
XT1643. Tried every firmware available on internet. No luck.
I have sent my phone to the service center after relocking bootloader. They are trying for a board replacement. I don't what happened to the phone. There was no problem when flashed the firmware for 2-3 times. Suddenly something went wrong. Kindly let me know when you get a fix for it.
http://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1643-updated-signed-t3460695 try this thread faced same issue worked for me
Please flash this rom https://drive.google.com/file/d/0B1N6dGU7FEXsSjR3QUtsRU1RTVk/view
This is correct Rom for Indian Varient XT1643, I got my everything working.
Downloaded firmware, flashed using mfastboot, still no luck. Fingerprint is absent from the setup wizard and in the OS, and one IMEI is available. Not both.
Have you faced this issue?
Hi there I have downgraded my ROM n soft bricked it. But after unbrick imei was lost so I used qfs tool to feed the imei and it worked but since then I can't use any marshmallow or lollipop ROM on my phone and even if I install it my imei get changed to 1234567123. N even if I repair the imei still I can't use volte. Even after flashing modem n using patches. Any idea what might b issue n what will b solution for it . thanks in advance
After following the directions to root a Samsung Galaxy Note 4 Verizon - SM-N910V from this thread: Easy Guide for How to Root Verizon Galaxy Note 4 I noticed I could no longer see my SIM card and also had no cell signal. Then I noticed my IMEI was blank and CSC and other Information in the 'About phone' > Status was missing. I followed the direction in the above thread carefully as I'm not new to all this and know the details are critical when rooting and flashing. I read through many threads here referring to solutions and found many referred to restoring nv_data.bin, .nv_data.bin and so on. None of those existed on my phone. Interestingly none of those files existed on other rooted Samsung phones I have where they were said to be even though those phones had no problems and had good IMEI numbers showing, cell phone working and so on.
In the process of trying to find a solution one involved using the Service Menu which can be accessed on rooted phones by various means - normally using *#0011# in the dialer and following up with some other key input to access it. On my phone all I saw was a big BLANK with no Menu showing up. It seemed everything I tried was a dead end. I tried the Dr. Ketan's IMEI Tool SGN4 with no luck either. Some of the solutions suggested that if you had DOWNGRADED a ROM the fix was to flash a newer Modem firmware. But in my case I had not downgraded - I had upgraded from LL 5.0.1 to 5.1.1. But when I looked closer I realized the directions that helped me root this phone did not upgrade all the firmware. The modem was still 5.0.1. So even though I had upgraded rather than downgraded I decided there was a good chance that upgrading the Modem might be the solution - at least for the IMEI. To my surprise it fixed all the problems.
Note that you should always do backups (preferably a complete backup with TWRP or similar) before flashing anything new.
So if you have any of the above problems the solution was actually fairly simple and easy. Get the updated modem firmware - in my case the BPA1 version (which you can find a lot of Galaxy Note 4 firmware in a thread here on XDA) and flash the newer Modem firmware using the latest Odin into the 'CP' (old term was Phone) slot and upon reboot you should see your Service Menu reappear, your IMEI will show again, you can see your SIM card and your Cell service will work once again.
I got my firmware from links in this post by hsbadr: https://forum.xda-developers.com/no...mware-firmware-kernel-modem-recovery-t2902574
Make sure you know how to use Odin and look around here on XDA for help with that or how to access the Service Menu. You don't need to access the Service Menu to fix the above problems but having access to the Service Menu can be helpful for many purposes.

so wait.....you had a note 4/with the original KitKat firmware on it still? i don't understand why you were attempting at 5.0.1 the root method was intended for 5.1.1 bpa1 but it would probably work at a lower api. but that still doesn't explain why u were rooting at that point unless this is way old and your just now posting thread .

No this did not have KitKat on it. It had Lollipop 5.0.1. This is what I did just in the last week or so - not old. I followed directions by Tripper511 as that was the only way you could root this verizon Note 4. Do you know of some root method for 5.0.1 - I couldn't find any anywhere and Tripper said you HAD to be on 5.1.1 for his method to work. It did work so all was good. You aren't confusing versions are you ? Kitkat = 4.4.2 and 4.4.4. Lollipop = 5.0, 5.0.1, 5.1.1 and so on.

incredible bud ... I bought this device new and it came with that firmware . 4.4.4 was never released to the general public due to stagefright exploit but if preorder u got it (I work for Verizon BTW) that was almost 4 yrs ago . you managed to find a note 4 with original firmware .... did you just buy it ? I remember we had them new for 149 now (new was thinking i should get another) but I didnt realize the firmware was still what it rolled out with. I would have thought they would update . but maybe they need activation becuz vzw only ota and Sammie NVR messed with it long note 4 really similar to note 3

Not sure of the history of the phone - it had broken S-pen sensor but other than that looked totally new - no wear at all - no screen burn, no nicks or wear anywhere. Bought it used from a guy on CL. I was surprised also that it only had 5.0.1 on it.
I followed Easy Guide for How to Root Verizon Galaxy Note 4 as well but I already had root. That allowed me to skip the root process and get full TWRP and TB backups. It all went smoothly except I had no IMEI, wouldn’t see the SIM card, same symptoms as OP when finished. I restored EFS and then modem from TWRP but it didn’t help. I went back to 5.0.1 and everything worked but got a backup of 5.1.1 first.
Droidzer, the modem firmware you link to is for T-Mobile Samsung Galaxy Note 4 (N910T) and I don’t see 5.1.1 anywhere. Is this a mistake? I’d like to do the same as you and restore the modem.
Edit; I found the sm910v modem firmware. I'll give the upgrade another try soon.
