Hello,
So bought my note 2 from amazon, international version, sim free.
So i rooted it and fired a custom firmware on it.
Decided i prefer having the functionality of the s pen and wanted to reinstall the original f/w.
So managed to get an original samsung firmware (BTU) csc.
All is well on it apart from my sim card does not work in it (no service).
works fine in my old phone still.
It doesn't allow me to update it over the air and kies is a nightmare.
So im stuck with a tablet at the moment that I cant update.
I think I may not have the correct original firmware but I dont know how to determine which one will work!
Any input would be appreciated....
Thanks
Dan
You seem to have stumbled upon the problem introduced by Samsung in their newest kernels (they are used in newer ROMs).
The kernels cause IMEI number to not be recognised after flashing old firmware once the new one was installed. The only recourse is to root again and flash back one of the newer roms (Phoenix, Omega or Android Revolution will do nicely) or try to find original Samsung firmware for your region, but it has to be one of DM6, DF1 or DG1 at the end of the name and flash it using Odin.
Look here and remember to match your phone model number as well as firmware region.

I hope you've managed to keep a backup of the EFS partition. It's really important that you do.

Efs partition is where your phones unique identifiers like imei are stored. If it gets damaged or wiped and you have no backup then your phone is a brick, pure and simple.

Try and Flash an official dme6 or dmf firmware as per above poster. If imei is still blank then your phone is a brick.
I don't know why there are so many how to root blogs on the Internet and none of them tell you how to back up efs or why it's critical. It's a complete tragedy.
I've had to restore imei once to save my gs3. Was very lucky I'd flashed an omega rom earlier and the aroma installer asked me if I'd like to do a backup and told me it's important. I heeded the developers advice and backed up said files to drop box. Now I always do it immediately after rooting - all custom recoveries give an option to back up efs.
I hope it's not too late, it's sad for people to have to learn the hard way, best of luck.

Ive just read that if you flash the latest modem you should be alright. The post to guide you on this is by Dr Ketan in the original android development section.
I dont think your phone is bricked I think if you flash the very latest modem you should be alright. Just remember when flashing anything to your phone you should always make a nandroid back up first and copy it to your pc just in case for safe keeping plus a copy of efs folder. I hope for your sake you can sort this. And remember to read thoroughly all instructions before anything else. Look here and click the read this first it should help you..

Well I flashed the oldest note 2 rom I could find 4.1.1 and I have an imei number back!
Still won't connect to my phone network.
I does show networks now at least!
Emergency calls only.
So if I install the new modem on this old firmware would that work?

I'd suggest you backup your efs before trying anything else.
Does your baseband version display now?
If you've already had your baseband updated to the new versions then you can't use it with Perseus kernel. The new modems are interdependent to the new kernels and Perseus hasn't been updated in awhile.
If baseband is newer one then you need an up to date kernel and flashing a newer firmware will obviously address this.

You have nothing to lose at the moment your phone is a semi brick. I think by reading Dr Ketans guide you will be able to get that phone working again. I take no responsibility from the following link but I think you need to give it a go. If you havent backwd up your efs folder than this link may help you. Id say download this latest modem and recovery and again I take no responsibility for your device.

check if your IMEI no is correct. if it begins with 00 it means efs has changed. u need to restore it from ur backup. guides how to do it are available in the forum.

If you use the search feature and tap in "lost imei" all your questions will have answers. It looks like you have an n7100. And by the look of things you were on mc3 4.1.2 and flashed an older rom of 4.1.1 I dont think you can do that..

for that u will need to flash stock rom via odin. do not panic. this thing has become very common now. search in android development section of note 2.guides are available todouble bled it ok. just do not panic.read the guides carefully and double check what u r doing.
I had a problem like this except it happened when I flashed a rom. The rom corrupted my SD Card so I lost my backup and even after flashing stock it did not work. Eventually I sent it in to Samsung. Now I have learnt my lesson to keep a backup on multiple locations

Go to a alternate servisse centre and ask to change your IMEI with a Box! only way to solve the problem! tried all that is possible and this is the only solution! it´s not about crime we are talking here! it´s about solve a problem!

It is because of downgrade of your rom.
Some time downgrade results in conflict modem and efs data corruptions.
It recommend to immediate take a backup of efs files after root.
Now do fiollowing steps
1. flash DMC3 full rom( Not only modem).
2. Wipe data and cache.
3. Wipe dalvike cache.
4. Reboot device.
It may solve your problem.

DMC3 also older rom for countries mentioned above.
Flash mg1 or simply look N7100 all in one on my signature, look post #6 and download modem for mg1 (it will have kernel, recovery and modem) you need modem only for network issue but I recommend to flash all three as your current rom I think not sds patched.

Just in case anyone is interested, I pulled the APQ8064T/MDM9X15M modem via adb and put it into a flashable .zip
I have never seen this modem anywhere, so I thought I'd share it for those who might want it. If you are on AT&T, you don't probably need or want to flash it, but other networks in other parts of the world, including parts of North America (Mexico) and all of Central America, etc. do use it.
It's direclty from the Panama Stock 980h ROM.

I don't think so. I think what's much more likely is that the modem flashing ability on this device via CWM is non-functional, and anyone who thinks they've flashed a different modem that way actually hasn't successfully done so.
I have been wrestling with the RILJ issue related to my network, and as I understand it, in CM/AOSP, the modem string is just a placeholder. It's not a reflection of the actual modem, but in Stock ROMs, I don't think that's the case, because when I was on Stock AT&T, my modem behaved differently than when on Stock Panama.
The modem.img in your zip is larger then the one in my AT$t V10G zip also...
Niw im back on stock AT$T and this is my modem#

hmmm.....my F240K shows exactly the same baseband on stock i.e. APQ8064T/MDM9X15M....wonder if they are the same...
also if CWM is not flashing modem properly...how can you be sure that you have flashed it?
in CM/AOSP ROMs if modem string is placeholder is that because these ROMs don't flash a modem?
I noticed that the panama modem says AP08064T and the stock AT$T modem AP08064.
The "T" is he only difference in the displayed name. So I can see how it might be confusing lol.....

My suggestion would be to flash the hacked TWRP recovery by MadMack, it can be found in the CM10.2 Unofficial thread. I have used this recovery from day one and have had no problems whatsoever.
Link to Hacked TWRP by MadMack -> http://forum.xda-developers.com/attachment.php?attachmentid=2250186&d=1378908893
It is my understanding, that this recovery is for CM or AOSP based ROM's. I think you must use the CWM or TWRP that are included in FreeGee to flash the Stock ROM variants.
I installed the hacked TWRP and my modem still doesn't change when I flash a different modem.

I have 240L and I really hated the call to korea and other korean network apps on my phone. I wanted to flash some basic stock rom like panama or telcell. but whenever i flashed stock i didn't get my modem to work so I used cwm to flash modem. I have used LOKI recovery and one another apk which is available for download on xda.
In panama and telcell i do get the signal but whenever I tried to make a call my phone restarts. I tried plenty of time then I got tired and flashed a custom rom from Lamhoang ... its working fine but I dont' like the HKFriend kernel its slow!
I still wish if I could get the stock original rom to work with some flashable modem....
one more thing I have 32 gb phone with SD card and in some stock roms i get the 32gb rom but i never got my sd card working.

That question remains unanswered, but the best evidence suggests that the modem is not flashed via recovery in either CWM or TWRP.
I have a chance to pick up another E980 tomorrow in the afternoon for a pretty good price in my area, and if all goes well, I'll be back to the LG OG Pro.

In order to prevent imei loss back up the efs partition. you can google how to do that.
I'd just flash the appropriate modem, or try the rom with the one you're using.

Some people have reported that even after restoring efs partition and re flashing their modem , their imei number still remained 000000. I don't know what wrong they have done, but will it re store the imei number and signal?

Hello
I have SGH-M919. First, it had stock ROM, stock firmware, and it was SIM locked to T-Mobile, so I unlocked it with SRS server service (I live outside the US, so labs in my area didn't have the tools to unlock it, since it's only a US variant. Also, other methods of unlocking did not work for me, unfortunately).
In the unlocking process I had to flash custom modem file with Odin (it was required for SRS to work). After that, I flashed CWM and CM11 and everything worked fine except the GPS. It didn't work: no GPS satellites were found.
How can I resolve this issue? Thanks.
Go to the CyanogenMob forum. There are threads asking the same question regarding CM11

If it might be the modem or kernel then you can try re flashing the modem or trying a new kernel. You'll see a lot of GPS issues being asked about in the CM threads, tho.

Just flash the stock modem since you said it was modified, unless its still needed.. However, many users have lost GPS after flashing aosp/cm.. The fix is simple. First make a nandroid backup, flash a touchwiz ROM, get a GPS lock, and then restore your nandroid.

Sorry, forgot to mention that I already tried flashing stock rom but GPS didn't work (it did work before the unlocking), so it has to be a modem problem. I couldn't find a stock modem file anywhere.
Currently I'm downloading another stock ROM, so I will be able to bring up lbstestmode which might fix my issue.
EDIT:
The new stock ROM works fine, and the GPS was able to find signal. So, I as ou suggested and recovered the Nandroid I made before through the recovery, but now I can't find GPS again. What can I do?
NB4 modem is posted in the general section

Just flash the stock modem since you said it was modified, unless its still needed.. However, many users have lost GPS after flashing aosp/cm.. The fix is simple. First make a nandroid backup, flash a touchwiz ROM, get a GPS lock, and then restore your nandroid.

Is this a permanent fix for GPS?

I have searched for stock modem and found this.
Unfortunately, I do have a KNOX counter in download mode so it doesn't fit.
This guide links to another modem file (that works with the KNOX bootloader), but it is for MK2, and I need BN4.. What can I do?
EDIT:
The issue is FIXED! The GPS works perfectly! Ultimately, I did install the MK2 modem and although I have 4.4.2 BN4 it works just fine.
Thanks for everyone who helped me.

Good! If you experience any issues you could flash the full NB4 firmware as well

I don't think I should, I have a bootloader with Knox (it was stated that it's only good for 4.2.2 bootloaders - ones without Knox. That's why I installed the MK2.

I'm not talking about the modem, but firmware, it will flash the modem in the process and you can flash it with your bootloader.. Like I said, if you experience problems but so far you haven't seemed to

Before I flashed the correct modem files, I flashed the latest stock firmware from Sammobile which I believe contains the NB4 modem. The GPS still didn't work, only the Mk2 modem works for me

Still, the MK2 firmware just works better for me.
Also, if I can't flash the fixed NB4 firmware because the bootloader has Knox, how will it help me if I install the non-fixed version (which is included in the firmware)? I'd be stuck with the bad NB4! There's no way to install the fixed NB4 if I have bootloader with Knox, if I understand this whole thing correctly.
P.S I am not intending to argue or anything, I am just writing what happened to me. So, if someone has the same problem and he googles it he will be able to find some useful info that took me about 2 days to find (and your generous help in this thread, of course!

The firmware will flash with your bootloader.. anyway everything is working for you so there is no need to. If in the future you change your mind or have problems PM me and I will explain or help you with it

Same here
Sent from my SGH-M919 using XDA Premium 4 mobile app
I noticed that I was getting bad cellular reception in an area that should have full mobile coverage. So I flashed the 4.4.2 fixed BN4 modem and the reception is way better (from one bar to 3 or 4), and the GPS is still working.
So, the BN4 modem did flash although I have bootloader with Knox (so it isn't supposed to work according the the modem thread)
P.S. I'm quite confused. Sorry for the noob question, but what's the difference between ROM and firmware? Is the firmware just a package which includes the ROM, bootloader and modem?
