Will flashing 4.1.2 Stock Rom on N7105 mess the IMEI? - Galaxy Note II Q&A, Help & Troubleshooting

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).

EFS problem hindering flashers?

Recent stability update is not allowing the flashers to downgrade or limited to only roms with particular modems as it is causing to corrupt the IMEI.
Though our clever developers have found many solutions it has become a hindrance to many of flashoholics like me.
What do you think? Can there be a permanent solution to this? and most important why Sammys have done this. I do not think this is some kind of bug. It is done on purpose,like preventing people from frequenting flashing?
what do you say?
I agree with you, efs problem and partition table corrupt are such problems which make people to think before flashing

I am not flashing any rom for the moment.
Do asop roms suffer from efs problem?
After an update my IMEI has changed from what is under battery cover to something like 004999xxxxxxxxx after which I can't make phone calls any more , after checking I've discovered that the EFS file doesn't contain the IMEI anymore, when happened this my phone was not rooted so obviously I have no backup.I've flashed back the original ROM many times but it's still the same.
Do you think there is a way to find a solution to this?
Please give detailed description of what happened like which was previous rom and which rom you are now on and trying to flash....

Latest update is not allowing the downgrade of modems, so please reflash the nordic rom so that atleast you will have your IMEI back. I was on ARHD 17.0 , tried Omega rom which is DME6 and reverted to ARHD 17.0. In the process I lost IMEI. So I reflashed Omega and I had my IMEI
NOw ARHD 18.0 is also DME6 and I can flash it but not below that
Ok will try it.
Just one question please,do I need CWM installed on my rooted phone to flash a modem?

[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...

[Q] N7105 No IMEI with 4.3 firmware

Dear all,
I have searched the web and flashed my phone for over 20 times in order to fix it after my serious mistake, I got no clue and decided to ask for help here. My phone is N7105 bought in Hong Kong. I would try to describe my issue using the fewest words...
- How things happen
1, I downloaded the latest 4.3 TGY firmware from sammobile, flashed it using mobile odin pro as I want to keep the root. After that I cannot connect wifi. Searching the web revealed that this is due to the old bootloader issue as BL did not update if flash by mobile odin.
2, Biggest mistake here. I know I should try to flash the firmware again by PC odin. However as I was not able to have a PC access yesterday I decided to see if some quick fix can help. I found a wifi fix in XDA (wifi_fix_for_MJ2.rar). I know it is for N7100 not N7105, but as It stated it is a fix I though nothing harm (very wrong!!!) and flashed it. After that my phone got the wifi back but have IMEI damaged. The phone is not able to reconize my sim after that.
3, I flashed the 4.3 TGY firmware by PC odin after I got back to home. (So the bootloader is 4.3 now). IMEI still cannot be fixed and SIM cannot be read.
- What resolution I have tried
Now I fully understand what's going wrong and I tried the following fix, but they all not working.
A, Using PC odin to flash the latest 4.1.2 firmware. This not working as odin refuse to flash, should be the 4.3 bootloader prevented this.
B, Using PC odin to get root and CWM <- OK. And then got a 4.1.2 firmware in CWM update zip format, put it in ext sd card and flash it in CWM <- OK. My phone seems to downgrad to 4.1.2. IMEI still damaged, no SIM. And phone is unstable (may hang after a while if it put idle, need reboot). Although it is 4.1.2 now I think the BL is still 4.3, as I still can't flash any 4.1.2 firmware by PC odin. And everytime I flash 4.1.2 firmware by PC odin it will appear fail on screen, and also render my phone dead. My phone would then cannot boot up and require to flash a 4.3 firmware again...
C, Tried to use Kie firmware restore feature. It flashed the 4.3 firmware but can't fix the IMEI issue.
D, Tried the EFS Professional but I don't know how to use it as I don't have a EFS backup before.
E, I got a param.bin from a thread of XDA (not sure if it is a good one or not, but the writer said it is for N7105). I flashed it using PC odin, status unchanged. (http://forum.xda-developers.com/showpost.php?p=47861647&postcount=242&nocache=1&z=8137774079208057)
- What help I am seeking for
1, Any EFS backup from you for N7105 which I can try? Maybe I can edit my own IMEI no. inside it?
2, Any way to restore the EFS data from flash?
3, Anyway to get back to a true 4.1.2 BL such that I can free to use PC odin to try different 4.1.2 rom? Currently I can only try to obtain CWM zip rom and it did not help.
4, Any other way which you can suggest?
Thank you so much for reading my help request...:crying:

Yes, it helped!
I searched this thread before but it was intended for I9305 but not N7105, so I did not apply the fix before. But the file Param_Bin_I9305.tar turn out worked for N7105!
Still if there is a way to downgrade my BL to 4.1.2 I am very much appreciated.
It helped for my issue also.
Quick description what was my situation as it may help others:
Got a N7105 with a 4.1.2 ROM. For some reason installed rom for a AT&T version 4.4.2. Got a NULL/NULL imei and no wifi, mobile or anything on phone.
Trying to resolve the issue installed stock rom 4.3 (from sammobile) and stuck on loading screen. Few attempts later and waiting at least 20 min after each odin installation I've lost all hope. Installed ParamBin file from the mentioned thread and what a surprise - phone booted and all is working fine.
Thanks for this post, saved me.

[Q] Questions about going back to stock.

Hey guys,
I was running Cyanogenmod 11 for a while which I installed using the automatic tool online. During the summer I flashed Dirty Unicorns but I have issues with the camera and random rebooting. I just got a Galaxy Gear for Christmas and I've read that its only compatible with touchwiz roms.
I'm trying to go back to stock and I am ok with losing my root access.
I have an SGH-1747m on Baseband I747MVLUEMK5 and my service provider is Bell. The android version is 4.4.4 currently. Whats the easiest method to do this? I've read some concerning information that going back to an earlier version of android will soft brick your phone, but I believe the most current Bell firmware is still in Jelly Bean.
Is it as easy as downloading the correct firmware and flashing it using Clockworkmod Recovery?
Thanks
You should download the stock ROM from sammobile.com and flash it in Odin to get back to stock.

The latest version available for my baseband is 4.3. Will I run into problems going from 4.4.4 to 4.3?
Flashing in Odin will flash everything, including the bootloader and modem.

Thanks. So if I'm understanding correctly I just flash the latest firmware released by my carrier (4.4.2)? Is there anything else to watch out for when choosing the firmware?
Also, before flashing should I make a backup with Clockwork Recovery or any other program? Will Clockwork Recovery still be present after flashing with ODIN?

Yes, flash the latest firmware for your phone. Be sure it's firmware for the i747m and not anything else. Always make a backup if you ever screw up or want to go back to where you are now. You will lose everything by flashing the stock firmware with ODIN, even clockwork mod recovery.
Thanks. When I made a backup before going to Dirty Unicorns I used Clockwork Recovery. If Clockwork will be deleted by flashing with ODIN, how would I utilize that backup if I needed it? Should I use another program to back up?
EDIT: I flashed it and everything went smoothly. Sincere thanks to everyone who gave me help!

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.
