[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] sm 900, null imei and unknown baseband, no backup of efs or anything

hello guys,
i have sm-n900 galaxy note 3, my problem is that i rooted the phone before 4-5 months, at that time it wasnt successful so i flashed stock firmware ( N900xxudna6_n900odddna3_inu ) it was all working well for 4 months, now last night , i wanted to root it again, so i tried by flashing ( cf-auto-root-ha3g-ha3gxx-smn900.tar.md5 ) but it got stuck on screen "firmware upgrade encountered and issue, plz select recovery in kies and try again". so i again flashed back ( N900xxudna6_n900odddna3_inu ) and my phone started up, but no i dont have any signal, it says null imei and unknown baseband, i donno what i m supposed to do, i dont know what efs is or anything, its so complicated and confusing, sm 1 plz help me in simple ways.
P.S : i know there are lots of threads regarding this, but i have very little knowledge about rooting and stuff so i cant understand those technical words, so plz help me,

Search the storage for any backup...

try one of the latest firmwares. if dont solved, no solution. you can send to service. if no warranty sptbox or octopus box fixed it with super imei operation. it cant turned back original imei at this time.

I had the exact same problem when i installed the Stock S5 Final for Note 3 on my phone. Everything appeared fine at first, but i had no sound and the phone was rather laggy. Checking out the baseband and IMEI gave the whole null etc. Even flashing back to stock didn't sort it out. I too had no backup and the sorts, as i'd just bought the phone and wanted it rooted and running custom roms (fortunately i know how to root/flash well). Do you have any sound when booting the phone up? If not, then it looks like you may have the same issue i had.
What sorted it out for me was flashing the newest modem. As soon as i flashed the latest N9005 modem (I have the International Note 3), all started working well and the IMEI returned. I'd suggest trying that route if all else fails. Flash the modem in Odin, then return straight to download mode again and flash the modem again. That usually makes sure it flashed properly.

N910H stuck in bootloop

I tried flashing the stock firmware and now I keep getting the Note 4 logo going on and off every 5 seconds. Tried flashing 2 other roms and both show a failed sign on Odin when they reach hidden.img. I can still reach download mode and recovery mode though. I've also tried installing the stock firmware via Kies and its still stuck in the bootloop.

if you have flashed CM13 from RaymanFX build 8 or higher recently then you have a corrupt IMEI and that causes the BootLoop
also check if the C-roms or stock one are for SM-N910H and not C model , bcuz there are also bootloops caused by Modem , goodluck

I had build 10 from Rayman's CM 13 before this. Is there a way I can fix it? The one I downloaded was for N910H. I even tried one from Kies. Thanks for the reply

I can't seem to find it, could you please link me? Also can I apply these fixes even though my phone is stuck in a bootloop?

The bootloop is gone but I can't connect to my network. I couldn't backup the IMEI file because the phone was completely wiped.

Without the imei, you cannot use the phone for any cellular activities like sms, calls and mobile data. Also, editing imei is considered illegal so you will not find any methods to restore it here.

[Q][SM-A310F] Sim is not detected

Hi everyone, I have a Samsung Galaxy A3 6, and after using this rom JX's check ur SIX aka L'oogleRom 2018 for one week, I decided to reinstall a stock rom. So, i do a full wipe than I try to flash with odin my stock rom but it's noi working ! I tried many different ways but none of the roms work. Worse, my phone doesn't recognize my sim card Help me please

Wiping is still OK? Wipe after (or delete something specific in /data/data that probably changed), I'm guessing it was done before the flash. Or try firmware with a newer modem. If the efs was wiped, well it's not supposed to be wiped. Only if the efs isn't there, load a backup. Else, maybe only the partition/volume is gone and only the content remains, that'll be difficult to restore...

No signal / IMEI after flashing Superman Rom

Hi Guys, hopefully someone will be kind enough to help me out here!
So I flashed my S7 Edge with Superman Rom a week or so ago and loved the Rom itself, however all I have got since is no signal, no imei, and won't read my sim. I've tried everything I can 're flashing Rom, trying to replace efs file (no backup as it got deleted ☹) and tbh I really haven't a clue what else to try.
I did try to refresh a stock nougat Rom through Odin but this now fails due to boot.img ?
So bloody lost.
If anyone has any ideas what to try I would be really greatful.
Cheers
Matt

Thank you mate! ...seems that the firmware I was flashing was not the newest version so couldn't update the boot to flash. Downloaded most recent Oreo and it flashed through dirty. Had to then flash TWRP and new root before installing would complete past the dreaded 'No Command' with yellow triangle screen! (Probably my fault for dirty flash - but just incase yours doesn't fully wipe if you get same problem as me). Rebooted and Oreo installed no probs and both my signal and IMEI have returned!
Custom ROM flashed and all still working no probs.
Much appreciated for the help!
