Is your IMEI something starts with 0049 now?
If yes, your stock rom has the old modem. You need to flash newer stock rom from here http://forum.xda-developers.com/showthread.php?t=1896696

[Q] How do I get a new baseband to fix the signal?

Hi,
I had DMF1 baseband/modem version on my STOCK XEF (France) ROM.
I have used the same Stock (downloaded from samfirmware) and flashed it because I messed up my system through flashing GT-I9000 by mistake.
So I had DME4 Baseband, and I get no signale, Airplane mode grayed out.
I downloaded here a modem.bin , that I flashed through PHONE via ODIN, and I got baseband DMF1.
However, the problem is everytime I restart, I get baseband unknown and I have to restore backup of EFS.
I tried getting a UAE (my country) Modem (XXDLK7) but it is a modem.bin file and I don't know what to do with it, also it is not DMF1 which was the working one I had back then.
Any help guys?
thanks!
GT-N7100
Edit:
I got the XXDLK7 and everything works fine now, but now the IMEI is 004999010640000 / 01. Regardless of how many times I restored the EFS :\
I'm really desperate. I wish I didn't even root the phone.
Edit2L
So now I have two options:
1-XXDLK7, Working , with a Wrong IMEI.
2-DMF1, Works once per EFS restore, but correct IMEI.
:\
I'd go with option 1 if it works fine even the IMEI is wrong :/
There are modems here: http://forum.xda-developers.com/showpost.php?p=31986738&postcount=7
Hope it helps
BTW, I have a friend who owns a Note I with wrong IMEI, works fine and has signal and all, one problem though, he can't lock his phone lol.
with random IMEI the phone can call, answer etc..??

No.
Gladly I fixed this buy patching an OTA update through Odin Mobile with Root and Odin apk, then flashing (without modem) the Stock DME6 ROM.
then restoring EFS.
weird how Samsung couldn't fix it for me :/

n7100 error" not registered on a network"

Hey everybody, Hope u r all doing well..
Here is my problem
I installed leaked rom 4.3 through odin on my N7100 device and was working well
then it started to be slow so I flashed 4.1.2 rom via odin, and found that my imei has been changed to strange one with a message not registered on a network
I searched the forum and figured out that flashing xxdme4 modem will resolve the problem
So I flashed this modem through recovery and the IMEI turned back to the correct one, but still not registered on a network
Things I tried
flashed 4.1.1 stock rom, changed the imei
flashed xxdmb5 rom , changed the imei
installed Ariza Patch on 4.1.2 , it makes my imei 009444 and corrupted it with no network
flashed xxdme4 Modem, it makes my imei correct
also xxdmf1 modem, makes my imei correct
I returned back to 4.3 , the imei is correct and also not registered on a network, I cant make calls
I flashed the new modem of the leaked 4.3 xxuemj5 on 4.3 rom, Also not registered on network but imei is correct
I flashed criskello custom rom 4.1.2, The imei is correct but also not registered..
Here Is the Strange part, when I call the sim in my n7100 from another phone, It rings as it is working, but I have nothing on the screen. also when I turn off my n7100, and call it , it is said that it is turned off. also the signal bars increase and decrease according to the area am moving in.. So I assume that this is not a hardware problem
also I thought to go to warranty , so I flashed stock ddmc3 rom, but the imei changed and when I flash xxme4 modem it is back, and I reseted the flash counter. but the modem is not corresponding to the rom, so it will be refused at warranty, and I cant install higher roms, cuz this is the latest rom for the region Egypt, where I live.
The Sim card is working in other phones, Also I tried many simcards
So I have a working device with 4.1.2 Stock rom and Xxdme4 modem, my imei is correct, baseband and everything
Sorry for ur time reading this, But to make everything Clear..
thanks in advance
Hey there... I actually faced a similar problem with the galaxy s3...similar symptoms.. .sane strange behaviour. ...except that my imei was altered.... I couldn't do anything to rectify it...as I hadn't backed up es folder....If you have backed it up...It may work if you restore it.....I made my s3 by sending it to a repair center...not samsung....and they fixed it....hope this helps...sorry about your phone
thanks for your reply,, I don't have efs backup.
Also My imei is Correct, it it Not Altered.
I am sure it is a software problem and I really need a solution
hope someone will help me.
Is there anyway to completely delete everything, repartition the device and start all over ??
If your imei is correct then use ariza patch it will fix your problem
Sent from my GT-N7100 using xda premium
Thanks for trying to help. But i think u didn't read what i have done above.. my imei is correct with modem xxme4 and when i install ariza. It alters my imei. So ariza generate fake one and doesnt work
Any help??
Not Registered On Network
I am facing the same issue... flashed the Leaked 4.3 jelly bean leaked version bu somehow Wi-fi was not working. So i tried switching back to old 4.1.2 jelly bean. And since tehn I'm facing this issue. And after looking for some solution i came accorss this section on XDA... and realized my IMEI no. has also changed as you mentioned above...
I have no solution to this issue... just guessing because I read somewhere 4.3 comes with region lock feature and once installed you cannot switch back to the previous verison of Android OS... Can this be the issue... ??
If thats the case then I am assuming re-flashing leaked 4.3 should fix it but you mentioed above even that didnt wokrk.
I havent tried anything yet to fix it... downloading the most recent official 4.1.2 jelly bean rom (N7100XXDMG1) available for my region and see how it goes... Though I'm not very positive about it as you have already tried this...
Is there any one who can help us out.. ??

Not Registered On Network - FIXED
Hi,
I re-flashed the Old Stock Jelly Bean, the one I already had on my system (N7100XXDLL4_N7100ODDDLL2_INU). Even after flashing it I was getting the same error as mentioned above and then came across another page on XDA which mentioned about this issue...
I tried installing the relevant modem for my phone rom and region which fixed it... may be the modem that you have flashed is not relavant for your region and rom. You can go through the link and see what I am talking about.... It kinda worked for me...
I flashed Modem DDDMG1 and it got fixed )

I tried xdme4 modem , it restores imei on 4.1.2 but still not registered on network
I had been thru the same problem. I flashed a prerooted 4.1.2, rooted it again as it was giving some error, and then patched ariza. I have done this several times as I have been constantly trying to flash 4.3 which always resulted in emergency calls only, once I lost imei after patching ariza, so I flashed. DLK7 or DL7 modem forgot the actual name but you can search by my name to find that post. I have already posted about the working modem.

Sorry to hear that it didnt work for you.... Seems like you are not getting the correct modem file for your region & Rom, the only thing that I can think of right now is to check with your friend who owns Galaxy Note 2 and can extract the Modem file using the method mentioned in the link i shared earlier :
http://forum.xda-developers.com/showthread.php?t=2044937
And use this file to flash on your Note2. Also, confirm the status of Note 2 of your friend whether it is locked by some carrier/network provider or Factory unlocked, should be same as yours (Not really sure if that can cause any issue but just want to avoid any further issues that might crop up).
All The Best.
Thanks!
efs restoring query??
hello everyone, i ve a efs backup, backedup wen im running on 4.3 (xxuemj5). is it possible to go back to 4.1.2 (N7100XXDMB2) and restore tat backup (backed up on 4.3)? i had a prob (" not registered on a network") last time wen i went back to 4.1.2.
thanks in advance-
Some times we have to replace the SIM card.
When IMEI becomes invalid the service provider blocks the SIM card.
Try your SIM card in some other phone before replacing it.
dear bro.
i had the same problem with my n 7100 i hope this ll work with u
flash stok 4.3 rom n7100zsuemk3 u ll find it at samsung-updates.com hongkong rom
u ll still have not registerd network
flash this modem n7100ddemj9 for android 4.3 i think u ll have to root ur devaice and disable knocks
google this (GT-N7100_ModemMJ9) u ll find it
this worked for me but with this modem u ll get poor signal than other devices . its better than nothing any way .
Dr Ketans roms has an option to fix the network issue in aroma instaler of his rom, can you try with this.. Or other option, if you want to return to the 4.1.2 try flash the rom 4.1.2, install a custom kernel, apply ariza patch and them apply an efs restore.

[Q] N7100 No Wifi after "Emergency Calls" FIX and WiFi Fix (STOCK 4.3)

Hello Everybody,
I would like to begin by saying how much I've learned in xda-devs in the last few days just by searching around the forum and Fixing different things here and there.
This is such a great community that I decided to register
OK so heres the deal:
Last week i bought a Note-2 (N7100) running Samsung Android 4.1.2 (Israel Version) + Rooted
I wanted to upgrade to 4.3 but 4.3 isn't yet released in Israel according to sammobile.com and other people I asked.
I found a Stock Deodexed Pre-Rooted ROM here on the forums (I think version was MK4), Flashed it, and lost cellular abilities (there is signal but emergency calls only) and WiFi.
Flashed WiFi FIX by Dr. Ketan, and by installing Devil's kernel (Patched_N7100_MK4_KERNEL.zip) and GT-N7100_ModemMJ9.zip I was able to gain 3G Functionality back.
Phone was working great for a few days, but then I decided to upgrade to Dito Note v3.2 because i wanted Note-3 Functionality.
After flashing it, I lost the ability to register to network again, started receiving "UIds on the system are inconsistent " and phone crashed every few minutes, screen stoped working every now and then.
I immediately looked for a different ROM to flash, (couldn't find the original ROM I flashed but i found DrKetan_Custom_ROM_V6_1).
So i wipe the phone, cache, sd-card and everything besides formatting the internal storage, Installed this ROM but still had the same issues with ULDS on the system, phone crashes and display shuts down while phone is still working).
Desperate, I downloaded Stock firmware (With KNOX) and flashed it to my device (I used Odin 3.09 and flashed everything, BL,CP,AP,CSC that was included within the original ROM). this was the Seri-Lanka firmware if I remember right.
This time phone boots without complaining about system files, but got "Emergency calls only" (IMEI and S/N still ok!).
In addition, I now have bootloader with KNOX.
I then thought, maybe the modem version is incompatible with the Cellular frequencies in my country (Israel Freqs: 850,2100), so i looked for countries with similar freq and downloaded official firmware for Thailand.
Flashed it with ODIN (same as before, BL,CP,AP,CSC basically everything) device boots fine, WiFi was working, but couldn't register on network ("emergency calls only") even if you can see your provider while manual scanning, registers successfuly apparently,but still no service.
Fraustrated, I rooted the device (Knox turned 0x1 but it doesn't really matter to me cause no warranty anyway), installed Philiz and flashed the 2 Fixes I mentioned at the begining (Devils kernel + Mj9 modem).
This resolved "Emergency calls only" issue, but now i cannot open WiFi at all!.
I tried to flash WiFi fix that i found in this forums but it didn't work. I've given everything I have in the last 2 days trying to fix this issue but I cant seem to solve this problem.
Now I'm just thankful that I can start/receive phone calls with my device.
I can't seem to understand, how did I not have signal with stock ROM?
could it be EFS was corrupted somehow so that only MJ9 Modem + Devil's Kernel read it?
How can i FIX WiFi?
Included screen-shots of "About Phone" and "*#1234#"
Thanks ahead,

OK Thanks very much for all of your help.
Does it matter what version of 4.3 I choose to flash via Kies?
In Israel only version 4.1.2 is available and I know that going back from 4.3 most likely will erase my IMEI / S/N.
If i choose a stock rom from SamMobile does it matter what country it comes from?
I don't really understand why are there different modems to different countries, aren't all versions alike?

I don't belive in this approach, I know for sure that there is a way.
after re-flashing with Kies and getting "Emergency Calls" again, i tried to flash only the modem, and i saw that i lost connection with cellular but Wi-Fi was still working. only after flashing Devil's kernel it seems that Wi-Fi stops working..
I just got home and i'm not expecting any calls until tomorrow, I will look around maybe an alternative kernel will solve our problems..

Maybe we just need the correct kernel and modem, the problem is that no one's development. Another solution would be to discover how to downgrade from 4.3 to 4.1. For now, our only option is to wait for more solutions and development

OK, so as I promised yesterday, I had the time to dig in to this subject yesterday and I managed to find a solution to get both, WiFi and Cellular working (together!)
Here are the steps i took:
1) Installed Stock ROM 4.3 with MK4 as the main and BL version (this will install Knox but i already had it) and modem version MJ9 (Odin 3.09)
2) Root the device with CF-Auto-Root-t03g-t03gxx-gtn7100
3) Install custom Recovery (I used philz_touch_6.07.9-n7100.tar.md5)
4) Very important! After device boots it automatically attempts to perform update with samsung! DO NOT LET IT as it will install updated modem version. it is important that we have MK4 Kernel and MJ9 Modem for this to work.
5) Flash via recovery the following files:
a) Patched_N7100_MK4_KERNEL - This installs a patched Kernel only this time because we didn't let phone update version after boot, it will be compatible with Phones version.
b) GT-N7100_ModemMJ9 - This patches the MJ9 Modem.
After performing all the above steps I finally managed to get Cellular connectivity and WiFi together. Hope it works for other people as well.
I still don't understand why Stock Kernel with Stock MJ9 modem won't work, what do those patches contain that allows me to get connectivity to cellular network?
This device is not black-list and IMEI is still original and S/N but for some reason won't work with stock.
Seems to me like some of the ROMs maybe modify EFS so that only patched Kernel and MJ9 Modem will work and it's not backwards compatible.
Can anyone confirm this? and if so, is there a way to convert the "modified" EFS version to stock compatible version? or is the EFS file encrypted with propriety Samsung encryption?

Hi, as you can see modem version for you is ending with MJ4 so it's not the same as my version.
Look for a version that has modem version ending with MJ9 and then apply the patch (because patch is for MJ9 modem, and not any other modem from my understanding)
Hope you get your device working!!
More explanation
Here are the steps i took:
1) Installed Stock ROM 4.3 with MK4 as the main and BL version (this will install Knox but i already had it) and modem version MJ9 (Odin 3.09)
2) Root the device with CF-Auto-Root-t03g-t03gxx-gtn7100
3) Install custom Recovery (I used philz_touch_6.07.9-n7100.tar.md5)
4) Very important! After device boots it automatically attempts to perform update with samsung! DO NOT LET IT as it will install updated modem version. it is important that we have MK4 Kernel and MJ9 Modem for this to work.
5) Flash via recovery the following files:
a) Patched_N7100_MK4_KERNEL - This installs a patched Kernel only this time because we didn't let phone update version after boot, it will be compatible with Phones version.
b) GT-N7100_ModemMJ9 - This patches the MJ9 Modem.
Hi there, and thanks a lot for your effort, I am really confused about step number 4, I haven't detected any update from Samsung's side, can you please provide more explanation?
Thanks

@Larner had the same issue and i assisted him to recover
Return to stock rom
what I guided first unroot the device completely
Now go to stock recovery and perform a hard reset that should fix the problem if this does not happen nothing can be done.

Hi Tonylee,
i have flash MJ5 bootloader before but its failed
is Blpatch the same like MJ5?? how do i know which bootloader i have now??
is this a stock rom N7100XXDMG1_N7100ODDDMG1_INU_Prerooted.rar ??
i will try your advice and hope it will help me to make my phone work again....
Us an app called Phone Info https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo to.see what bootloader you have installed already. Post here what that is. The blpatch is the dmg1 bootloader, you cannot flash the dmg1 rom if mj5 is installed. Yes the dmg1 rom is totally stock. just pre rooted.
If it fails whilst trying to.flash the mj5 then.its likely you have a mk4 or.newer bootloader wbich means you cannot.flash dmg1.
in that case the only thing I coukd.suggest is to.flash the very latest rom specifically for.you carrier

Im willing to bet then that you have MK9 bootloader. This means you cannot flash any stock rom that has a bootloader MJ9 or older. Only MK4 and newer.

Right as id guessed your on mk9 bootloader. Ignore that now. Your knox warranty is 0x1 which is the tripped state.
You cant downgrade the bootloader lower than mk4. You cant flash a stock 412 rom If it is loaded with a bootloader Which I think Is the norm.
you have your imei so you can flash a stock 4.3 rom for your carrier or a custom recovery and custom rom such as ARHD

You could flash a spanish stock rom but id go with twrp recovery and arhd.
You cant downgrade your bootloader your stuck with what youve got now. Dont fret, im also stuck on mk9 since I flashed an mk9 rom for a developer to test something. If.you want to use 412 specifically there are custom 412 roms but you might as well.go.with 4.3 now

You cant downgrade you bootloader. You cant.flash these roms because they contain a bootloader that is older than mk4 which means it will fail.
the only.option you have for.flashing stock.is.to.flash a 4.3 one.
if you want older android on your phone you will have to go.down the custom.route
the only stock.roms that will flash ok are 4.3 roms or roms that dont contain a bootloader update (most of.them.do.do)

[Q] Not registering on Network / Wrong IMEI after flashing stock 4.3

Hi, I have just flashed Rooted Note 2 on 4.3 to the latest stock ROM which I downloaded from the SamMobile and now it will not register on the network.
The new version I flashed was the same as the old as i found it with the CSC N7100BTUEMK2 on sam mobile.
I checked the IMEI and it says 00499010640000 in status menu which is different from the one under the battery.
I did not perform a backup of anything as I was not worried about losing any data.
Any ideas what has happened to it and how to get the IMEI correct again?
I understand this is something to do with an efs file but in what way it has become faulty from flashing the same rom I cannot decipher
Any help much appreciated! :good:

From my experience:
1) Reflash the ROM.
2) Flash a custom ROM.
Both worked for me.
N7105 rocking AOSB with AGNi kernel,
Click "Thanks" if I was of any help!
Thanks, I have reflashed the current 4.3 rom UEMK9 and a slightly older UEMK4 with a DEMJ9 radio.
I have tried lots of radios - DM3, XXDME4, XXMI6, XXMJ5, XXMJ2, and some other modem.bin
From what I understand its when you go from newer to older roms that you get IMEI problems, so its prob useless to try pre 4.3
Its all a bit confusing to me and which rom has which radio seems like an arcane mystery.
It is quite possible that I flashed a same version 4.3 rom but my old radio was different and not knowing it was such a minefield on Galaxy phones I never checked that or bothered with a back up.
I may have to resort to paying the people at unlocksamsung online £26 to reset my IMEI
Can anyone tell me, is it just the radio that causes the IMEI problem and should I just trawl through flashing radio zips until my IMEI comes back so I can save the efs file?
BTY everything else seems ok SN is correct and wifi works fine, I just can't get on a network without my correct IMEI
Thx
i also have the same issue on my note 2 gt-n7100 and now phone does no respond to the touch post rooting and all..i am tired of rooting and unrooting the phone like 100 times allready and now my phone is stuck in loop
