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 .

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
ok here goes, first off, i apologize if this is in any way redundant to someone's else question. with the amount of people whose phone got wrecked with the 2.3.6 update im sure somebody has had the problem im having.
like many people i just clicked "install" when google pushed the 2.3.6 ota. my phone was running 2.3.4. rooted. when it rebooted, i was greeted with the android exclamation mark.
i happened to have a clockwork backup so i tried restoring my backup. and restore it did, but not the radio. after the google update my radio was something like NO GSXXK1 or so. i tried the radio fix here:
http://forum.xda-developers.com/showthread.php?p=14564429&mode=linear#post14564429
i tried reflashing the stock 2.3.3 rom from google, wiping the bootloader and all. ive in fact tried many many things that ive read on xda and google forums.
now, ive managed somehow to have a running 2.3.4 with cell signal. using the efs file copy method in he link above. that restored my 3g and ability to place phone calls but sms arent working. i did the *#*#4636#*#* thing and notice that smsc is 00, i tried to set to the right value of +17057969300 for Rogers canada but all i get is an update error followed by a crash.
and now, funny, my search button is acting weird, like an eye that keeps twitching.
im not very knowledgeable in this stuff, just enough to get by and install custom roms but clearly im in over my head now.
why did copying my 3 efs file in the root of the sd card restore signal? i dont think these files really belong there, so just what the heck happened?
is there a way i can restore my nexus S to google stock rom when they shipped the phone? i mean, a complete wipe, sd, boot, radio...everything.
if i can start back with the stock phone, i can re-root again and start fresh.
any ideas please??
im physically tired of reading everything, misleading information and constantly flashing back and forth hoping its gonna work. oh and mandatory angry comment: thank you google for effing up my phone!
edit:
the only stock rom i tried i the 2.3.3 stock update available in clockwork. made no results.
current specs:
my phone is a i9020a
current baseband : NO DGSXXKD1
current build: GRJ22
android ver: 2.3.4
core: 2.6.35.7-ge382d80 [email protected] #1

Thanks dude, i had actually done that and did manage to get a signal back. its SMS that just wont work and when do the INFO thing to set the right value, i either get update error or a crash.
i installed stock rom 2.3.4 and install radio uckd1. that made my signal work even without having to move the efs files on the root of the sdcard. but still no sms.
is anybody else getting sms problems? this was working before the 2.3.6 fiasco.
im with rogers canada, in ottawa.
ok, just to loop the loop on this one and hoping it will be of use to somebody else.
my sms issue wasnt related to my phone at all, once i had a signal back, that's as far as the phone was concerned.
i placed a call to rogers to let them know i couldnt sms anymore.
long story short, they tried many things but ultimately, its doing the "hard" reset on the network for my phone that did it. im sure there a better name for it but basically they erased my phone from their network, i had to wait about an hour for the change to propagate. when i powered the phone back, it resynced everything and sms was back online without a single thing to do.
Hi at all...
I need help ....my nexus s shows the dev IMEI004999010640000..so the EFS folder is corrupted.
What i did and what my problem is:
I bought my nexus s a few months ago make a efs folder backup like everyone recommend and everything was fine i run JB-DoubleX no problems at all. One day in the morning nexus s want turn on ....dead... i tried everything...nothing ....so i sent it for repair...last friday it come back with Gingerbread 2.3.4on it then i made the ota update to ICS and then flashed the last bootloader LC2 and radioXXI1 after that i flashed my standard JB ROM Double X. This time i don´t make a new efs-folder backup because i thought i already had made one and phone came from repair with same imei and serial number.
As i recognized that my imei was corrupted i thought no problem i have already a backup so i copy the efs backup folder in my phone like it is discribed in some treads here on xda but mei imei doesn´t change to the right one it stays at 004999010640000 now i run out of ideas.
Also courios things are that i have any problems with playstore or with calls, mms, sms all seems tho work normal.
Can anyone of you help me please...????
I have had this issue since shortly after the Nexus S came out. So over year and half. The phone is still in use by my wife, running latest jb build. Every feature works.
First, try to flash it back to factory stock. If that don't work, copy over the efs folder, but remember to boot into CWM and choose the "fix permissions" option.
Thanks guys for the answers...
But I have allready flashed stock ROM from Google Server (Gingerbread 2.3.x) with fastboot....not working.
Flashed Gingerbrad 2.3.x with Odin....same ...not working followed some treads here on XDA....allways same result....generic IMEI.
So now I have a backup of my efs that seems to mismatch to my phone after repair....so i think there is no hope to get back my IMEI..
I think its a md5 hash problem i believe that the md5 of the nv_data.bin(or an other file in the efs folder) must match to some other md5 somewhere in the system....otherwise the change is locked.
This is not a fact its only what i think by myself.....

XT925, JBBL and CWM 6.0.4.4
Has been running cm-12-20150408-NIGHTLY-xt925_jbbl for a long time.
Decided it was time to update, being JBBL there is only cm-12-20150417-NIGHTLY-xt925_jbbl which is newer.
Flashed that without issue and it appeared to be fine, however no wifi.
SIM, Bluetooth, NFC all ok, but when you turn on wifi nothing happens. Change screens and wifi is back to being turned off.
Hunted around, found a CM13 build for XT925, installs fine, everything works well ... still no wifi.
Went to a CM11 version ... still no wifi.
Rolled back to cm-12-20150408-NIGHTLY-xt925_jbbl which it has been on for about a year ... yep, no wifi.
Checked the baseband version each time and it is always vanquish_u_bp_100700.250.66.01P
I can get my way around flashing some roms, but I am no expert, so not sure if the baseband should change or if it is even related to this issue.
Any ideas or help would be appreciated.
Definite baseband problem
So after a lot more messing around, and reimaging and trying a bunch of stuff, I am now at "Unknown baseband" and have no radio connectivity at all.
There are a bunch of posts about this mostly for Samsung phones, the general theme is to get a stock image and reflash it. Or to try and erase the modem/ modemst1/ modemst2 partitions.
The issue is I cannot find a suitable stock image. Most of the links etc are dead as razr HD is pretty old now.
Its originally an Australian version of the XT925, though really that should not matter, any XT925 firmware should work I think, although I found the Rogers firmware and it bricked the phone pretty badly and took a while to recover it.
So if anyone has a lead on where I can find an image for the radio/modem or patch of that nature or has any good ideas on how to recover from this problem I would be grateful to hear.
Thanks.
some progress
well after more research, got a stock image installed, the trick was to use mfastboot.exe not the regular adb and fastboot.
Now have a baseband version back (same as before found a stock AU image eventually) however same issue as originally had which is now have mobile data connection but wifi doesn't work, auto disables when you turn it on.
Nailed down the problem to the persist partition, it was dead/corrupt.
Problem now is I need to get the files for it somewhere, I have created the wifi/bt mac addresses as there are some guides out there for that, but looks like I am missing some bin files as well.
Anyone able to have a look in their /persist and tell me what SHOULD be there?
finally fixed
After about a day of screwing around, its fixed.
Root cause, corrupt /persist partition.
The fix involved a combination of this guide
http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
and eventually finding a copy of WCNSS_qcom_wlan_nv.bin and a decent stock firmware. As well as a lot of reading, swearing and experimenting.
After running so hot for so long it now has a bit of a bulge at the back, I think after 4years the battery is now going ... lol.
However now successfully running CM13 and I think everything is working.
Hi to everyone,
I have this unusual rom in my phone, as I have read through the internet, the XXU1 stands for a HongKong region.
The problem is, that there's nothing about such ROM on the internet, as if it never existed...
The phone was bought as new through online shop..
It has been unlocked through idoneapps. I use it in Europe. GSM and MOBILE data worked fine until I forced to update it through ODIN to G900PVPS3CPK1.
I was able to get the GSM to work, but the WCDMA network isn't available.. and the messages are split into pieces when I send them. As I've read, that is how they're sent in US.
I had tried many if not all of the roms, modems, kernels etc.. available in this SPRINT galaxy s5 thread..
but none gave me back the mobile network 4G.
So I was wondering if anyone has heard anything about such ROM (my original one) or where I could look for it? Maybe you have an idea what to do?
I searched for you. Here is the result.
https://samsung-firmware.org/download/Galaxy S5 (Snapdragon)/5998/ITV/G900FXXU1BOD3/G900FITV1BOD2/
This page explains it all.
I think you remembered a character wrong, it is an F, not a P. if it is really a P, and you are sure your device model is SM-G900P, then you must buy a new phone with a wrong ROM. I don't think that happens a lot. G900P never has a G900PXXU1BOD3 ROM. I think you flashed a WRONG ROM in the first place. DO NOT flash the ROM in this post until you confirm that your phone's Model Number(you can check this yourself in Settings, About device) is SM-G900F.
Thanks for your response. The sad thing is that the phone is G900P. I have attached the screenshot below. I have made a full TWRP recovery of the rom before doing any flashing. I am able to restore it all except the modem, as TWRP doesn't restore modems.
If I put a newer ROM bootloader and modem and restore the backup - I get a bootloop. If i put an older one I get no signal and the lower buttons arent working. Though I found BOG1 modem to work with my current firmware, but it's not fluent. The phone feels laggy and GPS isn't working...
So I am looking for a complete rom that could work in this phone without any recovery..
Can you find ok4?? Runs awesome for me, use Odin to flash it, you'll lose twrp but then Odin twrp

Sorry for the late reply, you didn't quote me, so I did not get the notification that you have replied.
It's very weird that your bought G900P with a G900F ROM. G900P doesn't support WCDMA network, I don't know if it's blocked by software. But the link in my last post indicates that your reseller flashed G900PXXU1BOD3 for you in order to make WCDMA work. I don't know if you can simply flash official G900PXXU1BOD3, because the system with your phone may be modified in the first place. If you simply want to restore original backup with modem, drop back to TWRP 3.0.2-1 or 3.0.2-0, 3.0.2-1 wouldn't mount external SD card so you have to move your backup to internal storage, I didn't test 3.0.2-0 but I assume it's the least buggy recovery for G900P so far.

My mistake,
I believe I had tried to restore backup with those versions of TWRP. They don't restore the modem part and give me an eror (can't remember exactly how it sounds), but as far as I have read, TWRP does not restore modem. It is impossible. So I can only flash it by ODIN, but there is no such G900PXXU1BOD3 modem on the internet..
I wonder, what if I would simply flash the G900FXXU1BOD3 or never rom with F symbol, could it work out for me? Maybe you have read about someone doing that? So far its my only hope...

I don't know if someone deliberately flash a stock G900F ROM to G900P, it would have most likely bricked the device. But I have noticed a slight difference between the 2 pictures you posted, first 1 says baseband version is G900PXXU1BOD3, idoneapps says it's G900PVPU3BOG1, I don't know which one is more accurate. I couldn't find a seperated modem file of G900FXXU1BOD3, yet there is a way to extract it yourself, simply change filename extension md5 to tar and open it with compression software. After flash modem, restore your backup.
Edit 1: Maybe you need to flash CSC also when you flash modem. But no rush, just try modem only first.

Hello,
Curiously I have the same problem, I bought the mobile by Ebay to a Hong Kong user and it comes rooted and with problems I do not know how to solve, from the beginning the camera did not focus until suddenly by magic, it focused.
Now I want to do a ROM restoration but I am not able to find that version since from what I see in the answers you have offered here seems to be "trick", have you found any solution? I would appreciate it if you told me so please.
Thank you.
A greeting.
