Baseband & IMIE Unknown

after flashing a Rom (Gingerbread 2.3.4 T959VUVKG4 ) via ODIN, i have a baseband issue (baseband & IMIE showing UNKNOWN) I tried flashing some modems (ki1.tar.md5 / kh2.tar.md5 & etc) via ODIN but nothing worked for me...
Any suggestion / tutorial ?

I take it you cant connect to network..you probably click something extra on odin or just
Somehow it wipe your emei during flash..
Only way i known to restore this is if you have a backup of your efs folder on your sd card..No dont ask for anyone's else they are not going to give it to you..no one likes having same emei for several reasons!

Hey bro i had the same issue, when i Flashed to 2.3.3 i had noticed my baseband and imei are missing or (unknown) so i thought re flashing it would fix no luck. So what i did that some how magically worked. I flashed back to 2.2.1 and still no luck baseband and imei are still missing so i flashed back to GB 2.3.3 still no luck. So i flashed back to 2.2.1 but this time the only thing i had different was i had my SD and SIM card out of it when i flashed back and it restored my efs folder. Hoped this helped.

hi thr bro...so means u get back to 2.2.1>>>>2.3.3>>>>2.2.1 to get baseband works again? thanks

[Q] No Service. Baseband: Unknown, No IMEI

I have been running a rooted samsung infuse with various roms for the past 6 months. I went to flash the latest modem this morning and when my phone came back on I had no service. At that time I was running CM7 and updating to the KK4 modem.
As I have worked through this problem I have returned to stock via ultimate unbrick. I have searched all over, but cant seem to find a solution.
Details:
Samsung Infuse running Stock 2.2.1
Problem:
No Service
No IMEI - reads null/null
About says: Baseband Version: Unknown
after doing several hours of research and trying various things I have not been able to find a solution.
Any help would be greatly appreciated.

I am not so sure if KK4 would work on 2.2. It is a GB modem.
And flashing back to stock overwrites modem and kernel and all back to stock, except formatting internal SD.

It appears I may have some backups of my nv_data files under:
/efs/root/afs/settings/
with the following files:
.nv_data.bak
.nv_data.bin
.nv_data.md5
can someone tell me if these are backup files and if I just need to move them into some other directory?
What directory does the phone read the normal nv_data files from?
Thanks

If you have a backup of your efs folder why not just try putting it where it would usually go?

well the easy fix that adam outler said would be to delete the efs folder all together and you will get a generic imei number but i never tried that. somehow you wound up with corrupt files in the efs partition. but if you have backups you can try to copy them over the originals.
you can also dd the efs partition and tell it to ignore bad blocks with
dd if=/dev/block/stl3 of=efs.img conv=noerror
this will make a backup of whatever is still good for a last ditch effort to recover what ever files you can.
my guess is that you played with an aosp rom. i believe that converts /efs to ext4 since rfs is closed source. i dont know how our aosp kernels work, since it is all unofficial lb may have had a different way to do it. but im guessing the conversion either corrupted the partition or that the kenrel you have cant read ext4. you might just need to install a voodoo kernel for the phone to be able to mount it. im not really sure.

This was a long time ago. But I believe the solution was exactly what was said above. Delete the EFS folder and have it recreate your IMEI. You should also check to make sure you have a phone compatible modem. Check your modem and reflash another one if that's where the problem could have come from.

Almost same Problem
Even I have the same problem, but with a slight plus point
Sometimes, I get the network, but after a while,it's gone .
If I'm on a call (when I luckily get network) , it gets disconnected within a minute or two .. and in a minute ,I get back the signals (nd sometimes,it takes hours to get back the network)
What could the problem possibly be ??
Is there anyone on the forum to help me out ??
Thanks.
P.S : There is no fault with the Sim,I have tried multiple SIMs , the problem remains same throughout .

[Q] No service, tried everything

I got a p500h from my friend since my razr droid died and I needed something to hold me over until I can save up for the note3. It had 2.2 on it so I flashed CM 10.1 for 4.2.2. When I put my sim card in I had no service.
I checked the baseband and it was unknown so I flashed it for v.20 and it appeared but I still get no service.
I don't have gapps installed because I don't really need it.
And that's pretty much it. I can't think of anything else to try, can someone help? I'm using a non-smart phone in the meantime and it is quite terrible.

Try the old Baseband fix, that did it for me some years ago, not sure if you need the v10 baseband coming from 2.2 but the fix should work. You can find it here on the Forum.
If nothing works, use kdz to flash the Stock Rom and start over.

Thanks, I wanted to try that but when I go to download the milk_os fix at the bottom of this page
http://forum.xda-developers.com/showpost.php?p=14743798&postcount=2
I get redirected to some bull****(lp.downloadsetup.net)
And I just don't trust this thing, is this really what I'm suppose to download?

Is definitely the fault of baseband. Some rom is incompatible with any type of baseband. Try to download from play store an application with baseband-ril match...

Sounds like you have an old baseband phone, but you flashed a new baseband ROM on it. In that case, simply flash the zip indicated below (I suggest you mount /system in recovery before flashing, even though the script auto-mounts /system, just to be sure). I'm attaching two zips for the sake of completeness; the one you want is the Use_New_BB_ROMS.zip.
Use_New_BB_ROMS.zip -- Flash this zip if you're trying to use a new baseband ROM on a phone that uses the old baseband. If you have no network on 2.3 and above ROMS, your phone probably uses the old baseband, so this is the zip you need.
Use_Old_BB_ROMS.zip -- Flash this zip if you're trying to use an old baseband ROM on a phone that uses the new baseband. If you have no network on 2.2 and below ROMS, your phone probably uses the new baseband, so this is the zip you need.

I tried to flash it but I get an error: can't copy META-INF/com/google/android/updated-binary
Should I be wiping cache for this? Dalvik cache?
I used LGMDP-v1.5 to get bb v.20 on my phone in the first place, I tried to do the same with v.10 after v.20 didn't work but it just went back to baseband unknown. when I tried to download the milk_os fix it just linked me to some phishing page.

What recovery are you using? I've tried with AmonRa & CWM 5.0.2.0 and both work. Other CWM versions will probably work, too. Haven't tried with TWRP.
If this flashed successfully but you still don't have service, then you might have borked something when changing baseband in KDZ. If that's the case, then hopefully others will be able to help you as I've never touched KDZ myself.

I tried it, here's what happened.
First I just flashed it, I checked the baseband, it was unknown. Previously it was v.20 so I tried flashing in v.10 since this was a fix for v.10 AFAIK
Still unknown.
Tried flashing the fix again just to overwrite whatever it needed to overwrite and still unknown.
I'm back to square 1 on this one.

S6 Frozen on logo Please help

Ok to cut a long story short managed to get the s6 in the rom but only when I install a unikernel either v6 or v8.
When in rom the imei is corrupt 350000000006?.
Is the unikernel doing this? if so I've tried loads of stock roms but all seem to freeze on the samsung galaxy s6 logo what can i do to fix this?.
I do have a efs folder as I used es explorer to check and there seem to be a lot of files in there the only one i couldnt see was modem and im unsure if it is kept in there, I have tried flashing a new bootloader and modem but they continue to fail in odin.
Any suggestions?, BTW have managed to revert my imei to original as on the back cover of the phone with software but even so it still says not registered on network even though there are signal bars, Ive tried going to network and search network it finds O2 vodafone etc but it just says unable to connect try later?
There must be some expert on here how can help?, also does anyone think flashing pit file will help?, if so do you know which one i need.
Thanks

Help Needed with Samsung G920P after root

Hi Guys, I know I am an idiot for not following all those guides properly and now I think I have bricked my device?
Well I am in Australia and I have this G920P model on android 5.1.1 (Unrooted). All was working fine, I bought it second hand from someone, I believe this is a U.S Sprint version, But I had my Telstra sim working in it with 4g data without issues.
So I decided to root it (without backing up- I know my mistake) and then flash XtreStoLite rom (again without doing any backup of original Rom). After that My device did not detect my sim card and there is nothing in the IMEI section of the phone.
I tried to flash official G920P rom via odin which installed successfully, and it shows signal on my phone, let me make calls but No Data. Seems like it is not registering my phone on the network properly.
So what have I done to my phone? Any chances to recover it somehow?

Have you the efs folder in your / partition? To check:
-Open any root explorer
-Go to / and check if efs folder exist
-If exists any file into it, tell me.

Thanks for a quick response, I Installed a root browser app and yes I can see EFS folder there and there are a bunch of folders and files in the EFS folder. e.g bluetooth, carrier, cpk, Factoryapp, imei, lost+found.... and so on
Appreciate your help in advance.

Have you checked your apn setting ? Make sure your carriers apn settings are restored.

Ok. I'll look into it. Thanks.

Ok, I have entered my network's pan settings manually and I get can get the data working but it only picks up 3g not 4g. I can make calls too.
But every time i restart the phone it keeps on checking the network status and picks up the signal after 3-4 minutes.
Also its stuck on the Hands Free activation screen and keeps on re-trying it.
Any help would be appreciated if I can get my device back to a normal one. Any other ROM's should i try?

One more question guys, Is there any non - sprint ROM for this device G920P? Because when I bought the device, I had no sprint stuff on it. No boot up splash screen or anything. I did not make note of which build version was it on but it definitely said G920P and it was on android 5.1.1.
Thanks

You may find and extra menu by typing ##scrtn#. I wouldnt reset to defaut as those general would be sprints settings. Try to find your carriers apn settings online.You should be able to cancel the hands free default activation. Are you still rooted?

Stock or custom? If i find it i'll give you a notice asap.

I am now on a stock rooted rom. Would prefer to have a rooted rom. I have tried installing renegade but it get stuck on finding network and stuck in a loop.
Imei number is now showing up. But i wonder what version this phone was on when it was unrooted ? As everything was working perfect and i had no traces of sprint either.
