You cannot flash via Odin or via recovery? Is the device rooted (check for supersu in the app-drawer)?
You can always flash via Odin IMHO with your computer. There are also prerooted firmwares available here. Just check the forum.

I can flash via Odin and recovery and all proces is ok but when phone booting I dont have network and I check with some app from play store phone unlocked?

You must have broken efs
Anyway root your device and make efs backup. (read post #4 in first line on my signature)
It will be better if you make nandroid backup too on ext sd card.
Then you can flash any stock rom, in case you get issue then restore efs Or nandroid.
PS : such issue happens once in while, nothing to worry, just keep efs backup always and flash rom, once you are on xda, you can't keep yourself away from flashing )

Got the same problem. Just fixed it. I restored efs with this prog from http://forum.xda-developers.com/showthread.php?t=1922473 thanks to as i9000!!!
Just be sure that your phone is rooted and USB debugging mode is selected. Works perfect for me. Really hope it'll work for you too.

is there anyway to fix IMEI 0049

i am running custom rom and works fine i get my real IMEI but when i install n7100 stock rom with kies or odin i get 0049 fake IMEI and i can't use my phone for calling and all
i want to go back to stock so bed but i cant trying everyday LOL
help if you know how to do it...

Only way to go back is to have previously backed up your efs partition, while you were on your stock rom. Then once you downgrade to older version modem/rom simply restore your efs.

other thread got deleted but i have this copied so i am just going to post here so i can remamber what dr. repied
dr.ketan said:
Indeed flashing older modem (and so ROM) causing this.
I replied on other thread(my prerooted)
Flashing latest ME6/MF2/MG1 should solve this.
OR simply you can flash modem, you can find modem on my All in one thread(look my signature) post #6
And don't flash 4.1.1 , it can brick device.

Please stop creating duplicate threads for the same issue. In any case, changing your IMEI is a banned topic on XDA as its illegal in most countries,
You should have taken a backup of your efs partition before you started messing around (this is in all the guides). If you didn't then that's your fault and your loss.

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.

Big mistake not having a backup when you are flashing. For help just search this forum for invalid IMEI note 2

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.

Do u think it's possible to restore something you don't have???

Only ways flash the stock firmware chances are less but still worth to give a tey or send it for repair.

This question has been posted so many times... and if you lose your IMEI you can't recover it without a backup.
So it was more a consistent response than a lack of help.

Go to Sammobile website or samsung-updates then download a recent firmware for your country and flash the .tar.md5 via Odin.

Which Aroma Installer are you talking about?
Anyway creating an EFS backup is too late for you, sorry.

well to be safe just flash stock rom and try once with pit file and see if it restore if not just take it to service center before hard bricking it

Samsung will repair it alsong as you tell them that it didnt happen because of rooting or flashing roms. But back to your question, Your pretty much screwed without warranty

If you did not backed up .efs, you don't have, well, an efs backup.
I used this method for backing up my efs and I think is the best: here
L.E.: also..if you lost IMEI or it shows you a fake one, than nothing else will bring your IMEI back. (except, of course, the case in which you have an efs backup)

Any idea ???

I lost my imei number a lil. Time ago and I don't know what could be the cause of this
I tried two different things that day i.e.
I flashed a wifi direct file for kitkat 4.4 based rom and then I partitioned my sd card and after sometime I lost my imei no.
So any one can tell me what could be the reason

Reason u already told main.thing is recovery ... do u have a efs backup???
