I did not backup efs.

1 try flash your origin phone modem . Still not work
2 flash origin stock rom. Stock rom from here http://forum.xda-developers.com/showthread.php?t=1957218
This is different version phone forum of yor phone that why you flash wrong rom in wrong phone and mess up your baseband & Imei.
So you need to flash your original stock rom & modem to get its back.

Flashing stock rom will do it? Do i also need to flash modem too or the rom will fix it? and do I flash from odin or recovery?
Which is the correct modem file, ive been searching. Dr Ketan's modem file, is that the one? Flash thru odin?

Yes, flash both by CWM. A lot of user didn't know keep do something like you did.you not only one.
Make sure full wipe and double check your phone model before flash .
Since you said you on sprint so the link I post fr sprint

And could u post the correct modem file for my sprint phone. De-odex or odex which should be the one to choose for stock rom?

[Q] How downgrade to 4.1.1 from 4.3?

Is there a way to downgrade the Galaxy Note 2 N7100 from 4.3 to 4.1.1 firmware because I've been foolish enough to flash a 4.3 custom ROM without making a backup of the EFS. The phone has a service provider sim lock, so I need to downgrade to 4.1.1 or is there any work around to sim unlock my note2 on 4.3 without rollback the firmware to 4.1.1?
EDIT:
I'm currently using my Note2 outside the origin of the phone which is the Philippines, I'm currently residing in Manama Bahrain.

You can try to find the newest version for your phone, country and carrier on http://www.sammobile.com/firmwares/1/
I have not tried to downgrade with Odin, but I'm guessing it would work.

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-

I don't need the newest one, I need to find a firmware with a sim unlock app compatibility.

Then download the last version that worked for you.

I wanted to downgrade to a lower version of the N7100 firmware, preferably 4.1.1 since I need the sim unlock. The phone is locked to a Philippine telecom, I'm currently asituated overseas - I want to use the phone overseas, hence, the need for the sim unlock is dire.
EDIT:
One more thing, the EFS backup and nandroid backup got deleted when I wiped(accidentally) the sd card.

Did you ever find out ? I'm trying to do the same thing.

Yes, what I did was;
Enter download mode > Flash a custom recovery (It was TWRP in my case) > Reboot > Flash a 4.1.2 based ROM
*I was quite lucky though since I flashed a ROM with a separate zip for the new modem, I got stuck in the process of a full reboot after flashing the ROM. Whence, this should be the sequence I'm supposed to do to make the ROM work;
Full wipe > Flash ROM > Reboot > Go on with setup > Wait for the boot sequence to finish > Reboot > Flash newer modem > Reboot
*I got stuck on the first reboot routine*

another issue regarding the downgrade
Hi,
my N7105 is rooted, 4.3 is installed, knox had been installed but was deleted using Titanium backup. Now i want to flash it back to 4.1.2 again, but:
odin doesn't recognize the phone, i don't have any files to try flashing it via recovery mode and the official update function doesn't work, because it's rooted. I also don't know, if flashing via the recovery mode would work at all.
Am i bound to 4.3 forever?
Generally i simply want to downgrade to 4.1.2 as i can't see any advantage in 4.3 or -if possible- would like to try cyanogen
Best regards
Gerald

[Q] 4.1.2 to 4.3 Made device un accessible to mobile network

Hello there,
I live in India and my Note 2 is a Poland made and running with 4.1.2 stock ROM non rooted. But the device status was shown 'modified'. Due to that (i think) i was not able to get any updates. So i decided to download and flash 4.3 ROM via odin. I did exactly and flashing was success. But after that i was not able to connect to my mobile network. It shows the coverage, base-band version, operators around me, IMEI...etc. But failed to register on network. Sadly i found that my IMEI was changed. Then i searched in xda and found out few modem patches. To flash them i rooted device and installed recovery. Then flashed DMG1_MODEM and modem_XXDME4 but nothing happened. Phone is still not registering to network.
What to do ?

I assumed that your device history was imei null or efs corruptted which has been fixed under 4.1.2 version.by upgrading the modem it will surelly broke your efs again.use special box to repair the network, nothing else you can do.

you have to flash the factory-image via odin (i think this would be the poland one in your case). you will get this on sammobile.com. with this it recreates your efs including your imei. (had this problem also)
after this you can try flashing a different rom, but don't forget to backup the efs

Is it safe to downgrade from 4.3 to 4.1 just by flashing factory images via odin ?

If you have flashed the latest bootloader MK4,its not possible to downgrade to 4.1 as of now...

Will flashing 4.1.2 Stock Rom on N7105 mess the IMEI?

Hi all,
I'm planning to flash my phone back to 4.1.1 via Odin and then to to 4.1.2 firmware, found on Sammobile to carry out the unlock method.
However, I am on the DMF2 baseband, and have heard that flashing a new modem over this will mess up the IMEI.
Will this happen if I'm only flashing a stock rom over it?
Thanks in advance!

I used to flash 4.1.1 stock ROMs onto my N7100 from 4.1.2
I would go into a bootloop after flashing it but booting to recovery and wiping data and cache solved my problem. Just backup your EFS to be on the safe side though

flashing new modem will not mess up IMEI.
but to be safe, back up your EFS before you do.
Normally IMEI will be messed up if EFS corrupted during the flashing.
Most of the time, it will happened if you change ROM with different base version (and normally happened when you never read the instructions of the OP very well).
So, when you want to downgrade, please do backup your EFS first (especially if you are coming from 4.3, due to different bootloader/partition of internal storage).

imei lost after flashing

Hi,

Is there a way to restore it?
I tried flashing back to older modem and stock rom, but no luck. i have still no imei and baseband unknown.

Flashing a stock mod fixed this; got loads of help from OP

Flash your original modem, or any latest full ROM in odin

We did try that a few times, it did not work. I was genuinely surprised as we used a Swiss stock rom that restored the imei number and network connectivity.
