[Q] unknown baseband version, empty hardware version

Here's the story
1. this phone wouldn't boot up after the OTA update, the screen read "firmware upgrade encountered an issue.
please use software repair assistant & try again."
2. used odin 3.09 to reflash pit and the latest nc4 official firmware (I know it can't be rooted, but that's the only choice I have).
3. phone came back alive, worked for t-mobile and verizon sim cards.
Problem:
after a few hours or maybe a day, or maybe a restart, phone won't detect sim card, baseband version shows unkwown, hardware
version is empty, imei, network, MIN, PRL version, ERI version, imeisv, iccid are all "unknown".
What I have done:
phone will be back to normal if I flash the firmware again, I've use odin 3.09 and kies 3 many times.
I also tried flashing different modems, for ex, MI9, MJE, NC2 even NC4. But phone will keep restarting, sometimes the phone is working after
a few restarts. But eventually I will have the same problem again.
I was wondering if someone could point me to the right direction?

When you flashed the different modems, did you check settings/about the phone to verify that the modem flash " took"? Recommend entering Odin from power off, especially when flashing modems. FWIW, I'm not at all sure this will fix your problem, but it's worth a shot.

Yes I did. The baseband version showed MI9 when my phone was still working properly.

OK. Hopefully someone else will chime in with some suggestions.

one more thing I've done many times so far is, sometimes a full reset will bring it back to normal too.
settings -> backup and reset -> factory data reset.
I don't mind bricking my phone, but maybe someone knows other possible way, say, flashing EFS? I don't even know what that is.
I've been searching for the right solution but I haven't found one yet.

Never ever give up!
I'm the OP and I finally got it working. I simply ran EFS Professional v2.1.73, did a backup and restore of the EFS. That's it!

Did you figure out what efs is?

It didn't last long, and using EFS profession for EFS backup/restore never worked again.
I then saw this page the other day,
http://forum.xda-developers.com/showthread.php?t=2610757
So I used odin to flash
pit
official kitkat rom
I also checked these two,
erase nand
erase EFS
the phone booted up fine, I then turned it off and entered recovery mode, did a data and cache wipe, then booted up the phone again, that brought back my imei, my sim card worked again.
Unfortunately I'll lose it again once I flash a custom rom, or perhaps even a reboot.
I'm still searching for a permanent solution. But at least now I can use my sim card with a stock rom

Rom based on which region?

Can you please tell the stock rom based on which CSC ? or country ?
I'm having the same issue. Lost baseband and imei, but never got it recovered. even with stock.

I use this one,

Same boat brother, this is what I've posted. So far I'm a week in this situation, battery pull brings it back, any mod like Xposed with module where you have to reboot looses the baseband, IMEI etc. I have backup of the EFS and restored it multiple time with no joy.
Need some advice guys for Verizon my Note 3, I'm currently stock NC4 ready to. flash this bad boy ROM, after root access with TowelRoot, installation of BusyBox and Supersu no SafeTrap yet. Once I reboot in this state, I have the Baseband unknown under Settings-About Phone status all unknown info on IME etc etc. Off course I loose 4G signal all together. I may reboot again and it comes back. I know about EFS partition corruption and have multiple backup of My note 3 EFs partition. Even with restore it would still happen. I have exhausted all my knowledge learned throughout the years from you guys. But, I'm asking some help again. I am very familiar with all the terms about flashing/rooting so please feel free to throw some genius on how I can fix this thing.

[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

All I want is a reliable stock ROM :(

Hi all,
very new here and to flashing ROMs etc.
Anyway, bought a 2nd hand Note 3 a couple months ago. It had a custom ROM on it and I was experiencing issues with it.
I've since (after Google taught me), managed to get a close to stock ROM on it. But sadly Im still having problems, mainly WiFi and Bluetooth not working.
Can anyone please recommend a reliable, stock or close to stock ROM?
I dont need anything fancy...I just want to be able to use standard features (mainly WiFi).
Thanks all

I've been using the music of life note5 port 5.1.1 touchwiz rom for months and that's been fine for the most part. darkera13 released a s7 6.0.1 port like 2 days ago on the samsungvn forum, it's buggy but usable, but it's second version are sure to fix the little bugs it has (battery life is bad, can't access sd in pc, other bugs that don't affect me). There is one 6.0.1 s5 port here but I haven't tried it. If you really wanna try the latest touchwiz 6.0.1 rom, wait a few days/week or so for a more stable version, otherwise I'd try one of the 5.1.1 note5 ports in here.

Flash a stock rom from sammobile or samsung-updates via Odin .

Thanks

Have tried installing a stock ROM from Samsung Updates but still no Wifi or Bluetooth. Starting to wonder if its a hardware problem. WiFi etc does work sometimes, but then goes off for days at a time.
Really frustrating.

Could be anything. Even hw fault... Could you be more specific about:
What custom rom you had?
Is there any chance you had deleted something from efs folder?
Can you activate wifi and doesn`t find networks or the toggle is grayed and can`t do anything?
For bluetooth, can you activate it and doesn`t find devices or the toggle is grayed and can`t do anything?
Try this from sammobile.

Thanks, Im downloading now and will test it out.
Im not 100% sure what ROM it was as I didnt install it.
I do remember something about CM12 ?
Cant activate Wifi or bluetooth at all. It will try and turn on for either but fail and then grey out temporarily.
Ive only installed a custom ROM and havent done anything with an efs folder.

Could you please check if yout imei is there:
In stock rom it is in about device -> Status
Do not post the numbers here just look if the numbers are there

Anyways I recommend you the following:
Download official kit kat firmware xxugng1 and latest lollipop firmware for your country
Do a factory reset
Flash kit kat with odin
Do again a factory reset (just to go sure)
Reboot and do the setup
Root it with cf auto-root
(If phone takes too long to boot remove Battery and start you phone)
When phone is booted Download triangle away
Launch it and reset status and counter
Than it will ask you to reboot or boot in download mode
Choose boot in download mode
Flash latest available lollipop for your country
Factory reset
And than you should not have any problems
(Do backup before it will wipe everything in your phone)

Check correct IMEI.
Check correct modem s.
Check CSC.
Try another kernel
Could well be that you have the wrong IMEI .
I would be restoring my backed up EFS folder first .

If you had a TWRP backup of your previous rom, you wouldn't have been in this predicament.
Try updating baseband version.
Your safest bet is to download Samsung firmwares from 4.2 - 4.4 and 5 & flash it via odin in consecutive order and check if your hardware works.
Or else it might be a faulty HW issue.

A twrp backup would not necessarily fix the issue if it was a hardware problem and it sounds like it is a hardware problem if flashing the latest stock rom does not resolve the issue.

I never made a back up as the phone came with a custom ROM that started playing up within days of getting the phone.

Yes, serial etc all match.
Just looking at the baseband and the build numbers. Should they match? As mine dont.
Baseband : N9005XXUGBOJ1
Build: LRX21V.N9005XXUGBOK6

No they should not match .
Modems/ baseband are often a different build .

Did wifi ever work properly? If not, it may not be worth fixing.
The easiest solution may be to find another phone that has a smashed screen nd swap motherboards.

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?

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!
