Hello to everybody,
I want to ask something.I am in Cyprus and from here i take my Note 2.
The official version for Cyprus is 4.1.2 PDA: N7100XXDMB2 CSC: N7100VFGDMA1 MODEM: N7100BUDMA1.
I flash it with the leaked MJ5 and i know that it changes the EFS folder format and new bootloader with warranty bit.
I don't have EFS backup from 4.1.2.
So the question is :
Is there a safe way to downgrade it back to official for Cyprus.
latest 4.1.2 jb install odin your problem slove

I think you don;t understand correctly my question.
I know that it is safe to restore it to latest JB (ends with MG1 or later) because it is after June and EFS folders have same format.
The official JB for Cyprus is Before June .
This is my question.
Or at least if there is a way to do it
latest jb ends with mg1

If you are currently on leaked MJ5, then you will have the new Knox bootloader. So, if you want to downgrade, go to Dr Ketans thread and
1) Flash patched bootloader through Odin
2) Flash wifi fix through Odin
Then you will have old bootloader and you can easily downgrade
Thanks everybody for help ,but i am still not clear.
I know this about DrKetans bootloader patch.
My basic problem with downgrading is :
Even before MJ5(new boot) if you try to downgrade back to stock from first leaked firm it causes IMEI brick. If i downgrade to stock witch is lets say MG1(brazil) i will not have this problem. But this is firm for Brazil.
I want to downgrade to official for Cyprus witch is firm before June.2013= possible IMEI brick.
Any other opinions ?

Use a root explorer (probably the easiest way) to make a copy of your efs folder from your current ROM.Go through the steps to downgrade you phone as was posted before and if you loose or corrupt you imei then restore it by copying it back to system/ with the root explorer again.The 4.1.2 firmwares changed the modem.pit file way back on XXMEG4 and as far as Im aware it is the same as the modem.pit file in 4.3.If it doesnt work resoreing the efs folder then you also need to just flash the XXEMG4 modem too.Thats fixed it for a lot of people Ive seen with this issue.

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.

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.

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

Hello I have the same problem with my note 2 upgrade to 4.3 and I can not release my computer does not recognize the codes, just like you want to know how can I go back to 4.1.1,,,, help!!

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...

So using the phone like a tablet without GSM is the future for me ?
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).

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.

You'll not get any problem if you flash a proper rom on your device for upgrading, but backing up the efs is always advised.

Flash your proper official rom (Download it from Sammobile.com or Sampro.pl), After flashing, go directly to Recovery menu (By pressing Vol up + Menu and then Power key) and hit >>"Wipe data and cache"<< it'd get your IMEI back.
