[Q] N900T EFS issue - Galaxy Note 3 Q&A, Help & Troubleshooting

Alright so... I got this N900T and rooted it and tripped the knox warrenty bit.
I installed the latest DomPop and read how the efs partrition had some issues and it being easily borked, and well I didn't wanna risk it. Rather than look into how to back it up properly using better tools, I had remembered a command from the S3, su reboot nvbackup, which is supposed to back up the efs stuff to a safe place on the phone. However, upon finishing that command it bootlooped. Well, i then ODINed back to 5.0. my baseband version is unknown, IMEI is unknown, all of the typical EFS is messed up stuff. So i tried, stupidly, the other command to restore the backup, su reboot nvrestore, and upon running that command it forced itself in download mode unable to boot.
i odined back to the 5.0 firmware about 4 more times and nothing happened.
I searched and searched and i tried following http://forum.xda-developers.com/showthread.php?t=2567133, i tried the the script it links to remake the partrition for the EFS.
My serial is still on the phone, i skipped down to the part about repairing the imei. I put my phone in RMNET+DM+MODEM, however it doesnt get picked up by EFS Professionals NV Tools. Any more ideas or help?
Also, is it safe to flash the 4.4 Kitkat without the phone bricking?
If there is anything i cannot do on my computer, are there services cheapish i can send them to and have them flash my IMEI back onto my phone?
Thanks in advance!

Me can not follow

Okay, so I used "reboot nv backup" without first researching to to back up my EFS partitions. Upon reading further into the stuff, I have found that that method destroys your partitions and shouldn't be used. I then, kind of freaking out used the other function "reboot nv restore" which is supposed to restore the backup, but instead it caused my phone to not be able to boot. So I odined back to stock 5.0. I have tried flashing just the modem, I have tried downgrading to NK3(4.4) but that had not helped me either. My baseband is still unknown and my IMEI is still null.
Is the only way to fix this with a UART cable and box? Are there any paid services I can use online to repair those partitions? I attempted to use EFS Professional, however it couldn't talk to my phone, either the SPC Code or the 16 digit security code wouldn't work so I couldn't write the IMEI back that way.

Not sure how is this going to help but there was a user (other than the poster) managed to recover his imei. I believe you could use any help at this moment.

Sorry, I have tried this and it didn't work. Thank you for looking for me.

Have seen many people with IMEI unknown and none of the threads I have read managed to get it back. As far as I know you are now hard bricked, at least regarding the actual phone part of your phone.

Please Help !! Not Registered on Network. IMEI problem ??

Hello,
I have an S4 GT-I9500 and suddenly am having the "Not registered on network" issue. That is: I cannot receive or make phone calls and SMSs, all the rest of the phone is working OK (including Data Connection 2G/3G, which is confusing for me).
I am on stock rom Android 4.3, Baseband I9500UBUEMK1.
I think that the problem is related to the fact that a few days ago I have rooted the phone, and installed Titanium Backup to delete samsungs bloatware. However, after all deletions (I think that I have deleted only safe things), everything was working perfectly, but suddenly today I noted that I cannot receive or make phone calls.
I have read many many threads in this site, but I am still confused on what is the cause and the solution. I have checked the IMEI, and have found that the IMEI in the back of the phone is 3571****, and the IMEI reported by the phone´status is 35299****. I can´t understand what might have changed my IMEI.
I went with ES File Explorer in root mode to the beginning of the filesystem, and have found the EFS folder ... there are many folders and files in it.
I don´t have a previous backup of this EFS folder, but I have read that there are some cases that the IMEI is recovered doing some procedures...
Please help me !! I don´t have experience flashing ROMS or modems but if there is hope ...
Thank you very much.

Something similar happened to me some weeks ago, but my case was different because I lost my imei but it was a generic one, (started with0049..) Everything was fixed when I installed a stock firmware through odin. Go to sammobile, download any firmware suitable for your model and flash it following these instructions: http://forum.xda-developers.com/showthread.php?t=2265477

Thank you for your answer. Do you think that is better to go flashing directly, or a factory reset should work also ?
Am I going to have any problems with the fact that the phone is now rooted, and (I think) with Knox in "non-stock" ?
Thank you.

I don't think factory reset will work, I'd flash the firmware. Flash a stock one, through Odin.
As regards knox... If you rooted the phone you might have knox warranty void 0x1, it depends on the bootloader. When you enter in download mode you will find out. If you still have knox0x0 or nothing displayed it means that warranty void was not triggered. Anyway flash the same firmware that you have now. You can find it in sammobile web page. Hope it works!!!!!
Well, finally I went with the phone to a repair technician who fixed the IMEI problem using a Octopus Box.
The reason the IMEI was altered is still unknown.

[Q] Looking for Stock 4.4.2 for AIO/CRICKET

I have searched everywhere with no luck. My I337Z was 4.4.2 (after OTA) working well, no root, no unlock. Suddenly IMEI and Baseband go null. So what I did first was to restore it to factory settings, which didnt work and also some native apps like Contacts stopped working (not opening). I tried to restore it through KIES, it put my phone in Emergency mode, no escape there...I then went to the Factory files http://forum.xda-developers.com/showthread.php?t=2448794 which got my phone back to 4.2.2 and working...but still no Signal nor IMEI nor Baseband. I flashed MODEM and now it doesn't have any sound, wifi either....I went through KIES again and was able to catch the files it downloads when initializing the device, flash the System, MODEM and CSC, but same results and it is still on 4.2.2. Also when trying to flash Bootloader I get FAIL(Auth) code (I suppose because my BL is not unlocked)
My request:
I am thinking if someone can make a backup of System partition, I could put it into my phone as RESTORE through TWRP (not installed yet) I might be able to revive this device.
EDIT: I am looking build i337ztuubne2 since my bootloader is now ne2 because of the OTA
Suggestions are welcome!! Thanks!!!

KIES 2.6 or 3? You had to be root to get to TWRP. Did the Z model ship with 4.2? I would be surprised, but don't really know. try 3. Start in download mode. I use cricket as well but never a cricket device. I will be in our cricket retailer today, the guys are pretty much ignorant to anything more than activating but possibly one may have a Z/s4 we could pull a nandroid from. Doubtful.
Sounds like you need a warranty replacement. Lesson learned? Always backup EFS!

First, the phone came with 4.2.2, so I used the files that kies 2.6 downloaded (haven't tried with kies 3) but the phone had 4.4.2 when it started acting up. It was updated OTA. As of now, I am rooted with twrp installed, no issues there. Now, if you could extract a nandroid from one of them, would be great! I do want to be on KitKat and not JB. I can flash it through odin 4.2.2 with no WiFi, sound nor calls. I think because the baseband is for KitKat and not for JB

S5 IMEI null and Service mode blank

Hello,
I have this problem with my phone and i don't know how to fix it, the IMEI is Null and when i enter "*#0011#" the ServiceMode is Blank !!
I tried to use GS5_EFS_Backup but it doesn't work ! Also the phoe get hot a lot, and when i put it in charge the battery level of charge is stuck in 10% always.
My phone is rooted.
Help me Please.
Thank you
Sounds like you wiped your EFS partition without backing it up first
Phone is dead if that is the case
Some people have had success backing up another S5 EFS, then restoring it to the dead phone
Otherwise, take it to a repair shop, next time backup before messing about

Thank you Detection for your answer. So where can i find another S5 EFS, and how can i restore it.
Help me Please because i tried already to take it to a repair shop but they don't know how to fix it, that's why I wanna try to repair it myself, and i think its one of the repair shops who wiped the EFS partition without making a backup (because i give to 3 repair shops and they don't know how to fix it).
You'll need another S5, no-one here will give you their EFS backup as it is specific to their S5
A trusting friend / family member or an old 2nd hand S5 if you can find one, is your only choice

There is no other solution like flashing the PIT file using Odin and reinstate the stock rom or any other solution !
Nope, not if you've deleted the EFS partition - that contains the IMEI and Radios
Ok thank you, ill try to contact samsung after sales service.
Hi everybody,
I have same issue:
I needed to update SU-binaries and tapped accidentally on CWM/TWRP-Mode instead of normal. After this IMEI is null, Service Mode blank, sudden reboots and unable to install any Apps (always saying no free memory). uninstalling App causes reboot.
I have efs backup made with (PhilZ Touch) CWM, but I'm not able to fix the problem with it.
What I tried:
flashing Stock ROM + updating Bootloader in Odin
this Guide (except Samsung Tool and Terminal Emulator steps, as I can't install any App)
CWM script
I really don't know what else I can do. Does anybody have some other ideas?
Also backing up is not possible, now. EFS Professional says specified PIT file does not exist, even when I choose all partitions.
FIXED. Possible solution.
Fixed. Went to a shop to repair IMEI/EFS.
It seems there is something called "IMEI NV Generator", this should also do the magic and would have saved me some money.

Need EFS/IMEI help - I have backup but still not working

The Story
Don't even know where to start. Okay so I have a SM-935W8 (Canadian Version) and it was working perfectly fine running Project Dream rom the S8 one. I decided to flash angelo's Pixel rom for S7 Edge and for some reason when it booted, the network had a cancel sign meaning no network. Once I finished the initial setup, calling, messaging , and data weren't working. Luckily I have a backup for EFS and RADIO in tar, img. and tar.gz formats. So I downloaded the Partitions Backup app and restored the EFS and Radio files, it said successfully restored. I rebooted my device and the issue was still there, no network. So then I installed the stock ROGERS (Provider) rom from SAM MOBILE and it came up with some DRK error and my phone would not boot. So then I quickly used ODIN to flash twrp and then flash Superman Rom (Love it) and use dm-verity bypass.zip to get past the drk error. Then I attempted many other things but to no avail such as flashing the EFS tar through ODIN which caused a "Software Error" and phone to be stuck on a light blue software error screen so I had to use smart switch to FULLY restore the phone back to booting up, then once again I flashed twrp and Superman rom with dm-verity so I atleast have root and a decent rom to work from.
The Problem and What I Have at Disposal
So essentially, I currently have a new section in settings under Connections called "SIM card manager" for managing sim cards even tho I only have 1 slot, it shows that the SIM is ROGERS and LTE/3G/2G in there, but it can't connect to a network and keeps saying Not Registered on a Network. Also, there are 2 IMEI's since my phone thinks theres 2 SIM slots but I really only have 1 slot. BUT HERE IS THE MAIN ISSUE, THE ROOT OF ALL PROBLEMS, the IMEI is reading as "000000000000000" and the IMEISV is "01". Hence im getting Not Registered on a Network. No secret codes such as *#06# are working, keeps giving the Not Registered on a Network error.
I have the EFS and RADIO backups in img, tar, and tar.gz formats as well as screenshots of all my MAC and Bluetooth addresses, IMEI and Serial #'s and all that information. So essentially I feel fully ready to solve the problem but everything I try keeps failing. My EFS restoration says successful in the APP but upon reboot, theres no change. Flashing the EFS through ODIN messes up phone harder. When I use EFS Professional Tool, where do I place the partitions so they show up in the tool?
I used this post to try to fix it: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516
BUT when I'm flashing the combination through ODIN in AP, it goes to NAND write or whatever and gets stuck, sometimes it gets stuck on Analyzing files or something. I tried every single ODIN version. I really could use some expertise on this issue. A step by step written tutorial, some method anything!!!! Help on this post or even teamviewer or skype for live help would be appreciated. Please help and I'm willing to compensate for successfully helping me fix my issue..
Did you ever sort this out? I'm in a similar situation, except that it does occasionally show my IMEI but also 'baseband unknown'. But still no network access.
i hope i dont risk a warning, but you can use xposed and with root you can change your imei and baseband info.

Thanks, I've done so much to this phone now...
I did try xposed and have tried a different IMEI, it seems like it's a modem issue but there doesn't seem to be a firmware solution - I have tried so many stock roms(All the way back to the first Marshmallow and a bunch in between) and different custom roms too but in the end the error is always there: Not registered to Network.
I saw somewhere in my troubleshooting that some kind of cert needs to be patched because the phone did an update on a modified rom without the OEM unlock being on and then the EFS data was messed up or something like that (all of the research and troubleshooting is starting to blur). It seems like that fix isn't doable without a rather expensive piece of hardware (expensive if your just fixing your one phone I guess) and there isn't any firmware-only fix that can accomplish this patch so I'm stuck again.

Sorry, I should have clarified. I have an S7 (SM-G930W8). I only tried this thread because the issue was identical to mine and I couldn't find anything similar referencing the S7 specifically.
For anyone coming across this thread in the future, although mine was an S7 I think the issue would apply to both. I ended up ordering a z3x in order to use the patch certificate. But it wasn't that easy; the firmware had to be downgraded to marshmallow first which wouldn't work in Odin until I tried just flashing the BL and CP files first, then rebooting and flashing the AP and CSC files separately. In fact, the AP file froze the first time but passed on the second attempt. After that, everything was downgraded to android 6 and then the patch certificate option worked and my s7 connects to the network again.
I'm having a similar problem with my sm-g935w8 Rodgers but has been unlocked. A couple days ago i looked at my phone and it was showing a no signal symbol and I look for my phones information and it showed unknown in all categories, the imei say unknown, and it's not reading the sim. Help me

Note 4 N910C Emergency Call only (Not Registered to Network) IMEICERT:PASS (IMEI Ok )

Greetings Folks
I have a N910C and as mentioned in title recently I got stuck in to this issue
How it happened
I had CF-Rooted my phone and Odin flashed TWRP for custom ROMS so I tried a few and was not getting the perfomance thought SimplROM would do it for me in order to install that ROM it said in instructions to install latest Modem and Bootloader
So i tried downloading the ones given in v6C BL was downloaded but CP kept on giving me errors getting stuck at 7% on mega so being stupid I downloaded DPCB(MODEM) While ROM was offering DPK4
So everything went fine until after boot I realized am facing Not Registered to Network
Since I had experienced this before on other phone I went ASAP in dialer to check my IMEI & SN both are still intact
I knew about EFS unfortunately I backed it up on Phone Storage which was wiped for ROM and I forgot (So dont have EFS Backup )
I do recall years ago back when I had S3 I experienced this and sometimes flashing different firmware(CSC ,Modem) fixed it
What I have tried so far
I have already tried several stock ROMs most of em had DPI1 Baseband except 2 other ROMS no luck
tried combination file method too (the one that helps downgrade to kitkat i believe ) no luck
Tried XEO repair Firmware no luck
any suggestions ??
and on that contrary now that I am not on stock is there any way to find out which CSC and Stock ROM this phone originally was one or came with with IMEI or Serial I believe ?
Thanks in Advance
Anyone??
under the battery there's the serial number
install on your pc samsung smart switch program
run it with option of emergency software recovery - device initialisation
input the model of your phone
input the serial number
start
have patience and a good connection
your phone will (eventually) get the latest official firmware
https://www.blogtechtips.com/2017/06/24/easily-restore-samsung-device-firmware-with-smart-switch/
at least you'll have a working phone with stock rom
from here on you can try again and get informed better on what to do
good luck

Hey there bud I have almost tried most of fixes I could I'll give Smart Switch a try as I recall I checked before it didn't have initialization just the recovery mode, while in Kies 3 I did try initialization method by model and SN but it prompted device doesn't support initialization
Anyways do you think it could fix network?

Maybe restore the efs from recovery, if you have a backup that was working.

Yep. Same problem as mine. Im kinda lost now since i dont have anything; even in stock rom it cannot go beyond connecting to my carrier. It only able to read my contact.
Im guessing its a motherboard problem? Isnt it @w41ru5?

I don't know. Usually it's a modem issue when not recognizing the sim.
If it's a 910F snapdragon it might be the infamous eMMC issue.
If you have an EFS backup try to restore it from recovery TWRP.
Assuming its modem problem, its related to motherboard i guess, right?
Finally got the phone working, only to discovered that SIM not working. Really wasting my time and hype!
Plus, its hard to search for n910c replacement board here.

The firmware, not the physical one.
Did you try to flash the 4 files repair firmware?
This is an example, I don't know what phone you have
https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=7081
Did you try the SmartSwitch pc program?
"...4 file repair..."- what? Ive google it until im almost run out of data here and you have a possible solution? You must be active in note4 forum.
One thing i noticed that, the IMEI and Serial Number are different from the sticker included.
I will try it, but not immediately; waiting for thurday-friday for data renewal.
My phone is n910c
EDIT : just checked the page you gave. I have few question;
What should i do with the files? What are the step? What are the program needed?
Is it related to SmartSwitch as you mention; need to use it?
Thanks!

1. It's good you still have the IMEI. Not so important if they're different from the sticker. Where did you buy the phone from?
2. So if you go to check the 4 files repair, you need to search on that site the files for a 910C.
3. Did the phone worked on your country provider? If yes, maybe you need to search for the 4files corresponding to your region code.
4. These 4files have to be flashed with Odin

5. SmartSwitch is an alternative to get the latest firmware for your phone according with the model and serial number.

the "firmware.gem" are useless. the error says i need another package (i assume a quota) to download the needed files.
im currently testing "zfirmware", but have a doubt since it only give 1 type file (which country is it i dunno). but yeah, since my phone like that, it wouldnt hurt to try
EDIT : yep, nothing changed. the device not even bricked.

If something does not work, why do you give up so easy?
http://www.mediafire.com/file/a2fdo0xm9nat5jt/N910CXXS2DPJ3_N910CZTO2DPE2_ZTO.zip - this is marshmallow
https://androidfilehost.com/?fid=24269982087001472 - this is for lolipop
Put the phone in download mode, open Odin and try.
And try the smartswitch also.

I tried files from LP and MM. It didnt work. And also smartswitch.
I was hoping that it will brick the phone (if i ever missed a step or incorrect file) but it didnt.
Might as well try looking for replacement board (or even a refurbished note4).
Thanks though for the suggestion @w41ru5!
Greetings again folks reading your replies above I have been trying almost every fix there is out there
First of all about Emergency Calls Only/Not Registered on Network
It can be due to several causes its can be Hardware ie faulty modem
it can be bad network coverage
it can be bad simcard
it can be SW with EFS problems or maybe even on rare occasion a modem file that you flashed
EFS can be either bad IMEI with CERT : FAIL or Just Network with IMEI and SN intact
just dial *#0011*# and see if you have CERT : PASS ( also someone with good IMEI/CERT and working network can share screenshot so i can compare whats wrong)
I am certain mine is EFS related because it happened after flashing modem DPCB modem via ODIN (I had TWRP EFS backup but the blunder I made was backing it up on phone storage and being careless forgot it was there and was wiped for custom ROM flashing process)
So far what I have tried
Combination File Method (and even downgrade to KK 4.4.4 )
Repair Firmware that include AP,BL,CP,CSC and even PIT
Kies 3 or Older Smart Switch says (Device doesn't support initialization ) since initialization feature was removed by Samsung on newer Smartswitch(since it was being used for wrong reasons? read somewhere)
Several different firmware's
OTA update
My IMEI CERT says PASS if only we had a network patch like Ariza Patch (for Galaxy S3) for Note 4 then we would be in luck so far at this point I dont think flashing ROM's would even help with bad EFS our only luck is Box e.g Z3x or Octo dont know if we are allowed to talk about those here (ill edit post if not)
these box applications have Network Patch for most Samsung models but I don't see one for N910C in most versions
for those with bad IMEI they can try writing good cert or efs on note 4 since they have already lost it I am sitting on it because my EFS is good on that part and for some reason box app isnt allowing me to back up my CERT if I am able to back up current cert then ill give those a try but I would prefer current IMEI since in my country IMEI should be verified to use the phone or you have to pay tax
I know its Bad EFS for sure because using Box application I chose reset EFS(after backing up current faulty EFS with good IMEI) upon reboot phone's imei was changed with no SN network came back for few seconds then gone again ,this happened to many users that have tried resetting EFS so I restored my original EFS
if anyone here with N910C and root can give me EFS folder I can corelate if any file required for network is missing since i have good IMEI
Cheers!
