I was having trouble getting back into TWRP recovery. It just kept freezing on the Team Win blue screen. It stayed that way a few minutes, then held in the power button, and it successfully got back into TWRP. Flashed my old backup again and all issue's were fixed. May have just been dumb luck, but maybe it will help someone.
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.

Hi all, I apologize for my low level of English. I want to tell that to write this report use the google translator.
I also thank in advance the help that you can give me.
Acontinuacion expose my problem:
I followed the steps in a tutorial, to release my samsung i9505 galaxy s4, exposed one of the most important forums, Htcmania.com my country, Spain.
By exposing my problem in the same forum that supra and receiving no response clarification about my problem, I turn to the more important to try to find a solution forum. I go to XDA-Developers.
I do a copy and paste of the report I wrote on the forum that I quoted earlier as I explained my problem well:
My s4 with Android 4.4.2 was completely "virgin" had installed the rom Stock samsung, was not released, was "Yoigo" any advanced recovery had not installed, and had no permits super user "root".
I wanted to release it (Unlocksim) seeking information HTCMania, and I found the following topic "Free S4 I9505 (Unlocksim) in 4.4.2" I followed all the steps in the tutorial. One of the "requirements" was to be root to do a backup of the EFS before touching anything, and to use the application "Region lock away"
So no, I did root, flashing by odin CF-Auto-Root 4.4.2 package.
Being root installed the advanced recovery "CWM" philz touch. And I found myself at this point I made a backup of the EFS system being completely "virgin" that is, with stock rom samsung and android 4.4.2. I followed the steps in the tutorial that I have made previously to unlocksim. One of the requirements to release the phone was change the modem to modem I9505_DXUAME2_MODEM, so I changed the phone modem and followed the guidelines set by the tutorial,
Region to use the application could lock away briefly display an error is possibly to blame for me as I'm seeing. This error could display for two seconds, but from that moment everything seemed to work well, the phone was released. So I changed the modem again for mine.
At this point I decided to choose to install a cooked rom based on stock, namely Omega rom v38.1 for s4 I9505.
And at this point is when my headaches begin to appear. I have experienced problems with the release ... see, the issue is that when the network coverage data is in H + the phone works perfectly, but only if H is not able to load websites etc. This has led me to the edge as I can not be aware every moment of the type of data coverage.
My questions are:
1. Is there a way to stop the phone as he was before unlocksim, ie leave it as it was originally being from Yoigo? (Remember to keep a copy of SAI realized when the system was completely untouched.)
2. How I can solve this problem with the network coverage data?
3. What do you advise me to do?
Please help. Greetings.
you might want to try searching sammobile to see there is a ROM you can download and flash that's for your country and ideally for your phone provider as well. I've run into issues like this on a couple of occasions. One was indeed that the country's ROM I flashed uses differant frequencies and I had the same mobile data connectivity issues you're talking about. This is rare for the international Samsung phones but it does happen. The other scenario I ran into was after flashing a port of the Google Play Edition onto tit, which gave it extended network options, and everything worked quite well but when I restored to stock from a backup on my sdcard I had connectivity issues, once again just like you're describing. In this scenario flashing a fresh stock ROM entirely solved the problem.
Note that in the second scenario I didn't redo the data partition. Presumably flashing the system fixed it or reflashing the firmware partition reinitialized things the way they are meant to work for me.
search for I9505 (or whatever the model of your phone is) where it says search for your device http://www.sammobile.com/firmwares/
Google around the codes if the results aren't revailing enough for what's stock for you and try reflashing in odin. If it persists then backup your apps, wipe the data partition, possibly backup your internal storage as well if you have a stock recover, and try again. Beyond that I haven't had to deal with further problems than that yet but I saw that no one else had responded...
Hey guys. I know for sure there is another thread about a similar problem but the biggest problem I'm having is figuring out what to do next, or better yet, what did I even mess up?
I made a thread a couple days ago here asking about the LTE option on my phone and how there was none. It's an Intl' phone and therefore I guess doesn't work on Canadian LTE networks.
Before we start, I'm using TWRP 2.7.0.0 . My phone is the UAE version of the D802, which is the D80220C. My current custom rom is Liquidsmooth MS3.2 .
So I found a list of modems and flashed the one for Bell. It was for the D803, but the thread I was looking at said it was cross-compatible so I assumed that meant it's okay for me to flash it on my phone.
Even so, I backed up my EFS partitions just to be 100% sure. I even used the .zip file that automatically backs up the current modem files. So I thought there was definitely a way out if it didn't work.
I will give you the full story of what was done and maybe I can get some guidance on maybe something I did wrong.
1) I flashed the D803 Bell modem.
2) Reboot to system, LS3.2 hangs on start up. Tried a hard restart to see if it wasn't a fluke. Nothing. Still hanging.
3) Figured the EFS files were toast, so I ran the restore .zip for my EFS. Reboot, and still hanging.
4) Said WTF? and restored my first stable rooted stock rom. It booted into the rom fine, but when it got to the lock screen I saw the "Service Disabled" and the phone quickly crashed.
5) Didn't even attempt to restart on that rom. So I tried a couple terminal commands to copy the modems1.img and modemst2.img files to corresponding partitions. Copied both just fine, but no change. Still screwing up.
So, this is where I am so far. I am in the process of downloading the D80220C UAE .kdz file so I can try to flash that one first. If that doesn't work, I'm really at a loss.
When I read into this some more, all I see is people who have totally wiped their EFS files and having to spend a whole bunch of time using a bunch of different programs to get in an recover the IMEI number.
What do you guys think?
Some good news right off the bat. I found a KK baseband for D802 and flashed it. So now I was able to restore my LS3.2 rom and boot into it fine. I see my IMEI and MAC address and can get WiFi at last!
Mods, you can delete this thread if you wish.
Hi guys, I am new on this forum and it's (strongly) possible that I post this question in the bad section, if so, please excuse me it wasn't wanted .
In short, that's my problem:
I have a Samsung galaxy J3 2016 (sm j320fn) on which I had installed the resurection remix rom, but for some unknown reason the rom became unstable and applications started to crash one after the other, so I decided to flash an official firmware via odin, everything went well during the flash, however, when starting the device I'm immediately bombarded with a message telling me "The process com.android.phone stopped", after fighting with these messages, I could see in the settings that the version of the baseband was "unknown", so I tried to reflash the firmware via odin, but without success:crying:.
I also noticed that my tel did not ask me the PIN code of my SIM card .
If someone could bring me the solution it would be great, thank you in advance and have a good day.

You will need to format the data partition in recovery after flashing the stock firmware.
If your baseband is unknown the rom you installed could have damaged your EFS. In that case just restore the backup of the EFS you made.
