Hi,
I am newbie for Android and this could be silly question.
Is possible for me to downgrade from 4.1.2 to 4.1.1 with original stock rom (international version N7100) and no root?
If possible, could you write down steps that I need to take?
Yes, I did search the forum but it doesn't comes with step by steps?
Reason is battery drain too fast especially at night.
I had the same problem... You must be rooted first to do it...
Download the correct firmware (http://www.sammobile.com/firmware/)
Install MobileOdin (https://play.google.com/store/apps/details?id=eu.chainfire.mobileodin.pro&hl=en_
Copy the tar.md5 file to your external sd card
Open Mobile Odin and flash the stock rom. It even has an option to root it without effecting the status. My phone is rooted but it still says official. Then use TriangleAway to reset the counter to 0 and you're good to go.
You dont believe you have to be rooted at all, I did this last night, the way I did it was went into stock recovery, factory reset and wiped cache, rebooted, turned off, booted into download mode, connected to pc, opened odin and flashed stock 4.1.1 simple as. It did get stuck once on samsung logo I left it for about 10-15 mins, went back into recovery and wiped and factory reset again, rebooted and all was good and now Im back on 4.1.1 so far its been off charge for 3 hours or so and its only gone down 1% it would have been around 8-10% on 4.1.2 for me
I wasnt rooted before, was on stock 4.1.1 then upgraded to 4.1.2
Absolutely possible. I just did. Steps are,
1- Make a batch backup with Titanium first, on your 4.1.2 ROM.
2- Flash the stock 4.1.1 ROM via Odin.
3- Root it.
4- Go to recovery and wipe data, factory reset, wipe cache partition, wipe dalvik cache.
5- Now you've 4.1.1 fresh ROM, install Titanium and restore all missing apps and system data.
6- Now you've a fresh 4.1.1 ROM with all the data and apps.

Jujuburi said absolutely correct, why you need root to simply flash stock rom.
Just to add.
After downgrading as described by jujuburi above, your device still will have new bootloader and that won't downgrade by procedure said above and so you have to re root with cf auto root or one of the CWM recovery, exynose abuse apk won't work.
Downgrading bootloader is needs different method and no need to describe here as it is not recommended/required at all.

The easiest way to do it without a pc or raising your flash counter is to follow my tutorial.

Okay, that mean if I dont root is 100% i cannot downgrade it to 4.1.1?

It's only a temporary root. Once you load the tar.md5 in mobile odin you have the option to keep it rooted or not. Just simply keep the box unchecked and you'll be good to go. If you're not rooted right now root it with cf-autoroot to keep your status as official on 4.1.2 then install mobile odin and finish the steps.

????? Your guide isn't the easiet way at all. The OP didn't say he didn't have access to a pc? And flashing stock roms via odin doesn't raise flash counter afaik?
Also your link to odin is a paid for version which isn't required.
+1
Absolutely right
-No root needed to flash using Odin, neither flashing stock ROM with PC odin raise flash counter.
hi guys
a have the same sleep drain issue with 4.1.2 and going to odin flash 4.1.1 but do i have to wipe data/cache ? and if so do i have to wipe b4 or after the flash ?? thx
It is not compulsory, but in many cases during downgrading, after flashing ROM device may gets bootloop OR stuck at samsung logo. in such caes you need to do it.
But i do prefer wipe always after flashing ROM for better performance, you can do it after flashing.

Hello all,
I have been reading, viewing videos etc for past 4 days. and have asked questions on youtube to people but no one replied now you are my BIG HOPE..
i have an international version unrooted galaxy note 2. I dont have much details about baseband etc as i never jotted them down before upgrading. But i do have details now after upgrading to 4.1.2.
Baseband- N7100XXDLK7
Kernal 3.0.31-679347

Build Number
JZO54K.N7100XXDLL7
AP: N7100XXDLL7
CP: N7100XXDLK7
CSC: N7100DBTDLL2 (which is germany)
I am downloading N7100XXALJ3 N7100DBTALJ2 from dr.ketans N7100 all in 1 old rom posts of 4.1.1 Oct 2012 as thats what i cuold find for DBT germany firmwares. Is that right one........???????????????????????
like others i upgraded to 4.1.2 and have been facing battery drain problem. first of should i wait till samsung comes up with fix in next update or shuld i revert back to 4.1.1.
I read this post as and it is so confusing-
Battery only lasts 1 day so want to go back to stock firmware 4.1.1 and want flash counter zero and everything legit. one member said root is needed then other said its not. then dr. ketan in the end say just to go back to stock root is not needed and just flash with odin and it wont increase counter as well if flashed with odin pc. is that right that we dont need root to just go back to stock 4.1.1 as he said.?
---------- Post added at 09:44 PM ---------- Previous post was at 09:24 PM ----------
Now i am confused as i have multiple options suggested by all in this thread--
* If root is not needed should i just download 4.1.1 (enquired about the firmware N7100XXALJ3 N7100DBTALJ2) and flash it with pc odin just like bradmax 57 said and keep it all legit and will i still get OTA samsung kies updates in future..?
OR
* Should i root my phone first using cf-auto root with method given in your N7100 all in 1 forum and then flash 4.1.1 with mobile odin and then remove triangle away once and for all.? if we go this way obviously phone will be have full root access with limitation of not being able to flash zip files from pc (but will be ok with mobile odin for that) and cant use nandroid backup and restore - i am not fussed about these things but want my phone to be legit for warranty and do need future updates OTA and from kies.?
Also do i wipe cache, factory reset from recovery before or after flashing 4.1.1 as bradmax57 had to do it twice before flashing as it was getting stuck at samsung logo but on the other hand dr.ketan suggests to do it after flashing 4.1.1..
Kindly help.
Thanks in advance for your precious time.
Here i giving clear answer and you should not have any confusion.
-No need to have root to flash 4.1.1 with Odin
-after flashing, you may stuck at samsung logo, in that case you have to reboot to recovery and have to wipe cache and data
-I don't recommend to downgrade, as latest 4.1.2 having SDS fix, on 4.1.1 you device can be brick without any reason. if you have battery issue, download latest MA6 ROM , not necessary you will have to flash DBT ROM, you can flash any country ROM and whenever your country get same update, same way you can flash that ROM with Odin.
First off a big big thank you to dr.ketan, mazdamiata and jujuburi who assisted me and cleared confusion. I have down graded to 4.1.1 easily and see a massive battery difference already. All i had to do was download stock firmware for my phone csc region and flash it with odin. wipe data , cache in recovery mode as it did get stuck on samsung logo and its all good. no root needed and flash counter etc remains untouched as well..

So you're saying we can flash a different rom to our phones without it breaking? I find that hard to believe. Why would there be different firmwares then from samsung? I need TTT firmwares, so I could flash any DMA6 firmware since mine isn't available yet?

dr.ketan said csc doesnt matter. if we flash rom of different country. the rom has kernal, csc information. the only thing is we will get ota or kies update of that country whose rom we flash. rest i wouldnt know lets wait for a word from dr. ketan or some one on this

You can flash any ROM of N7100 to your N7100, that is that simple.
I never seen a case of bricking by just flashing stock ROM. just selecting own country ROM will help you for better language support, and some priority/selection of application for your country on play store when you search OR google suggest you. You can flash any country ROM which is latest and still not available for your country.
I wanted to try a few custom firmwares on my GT-N7100 Note 2. So I rooted it, installed CWM, backed up original firmware, tested a few roms, restored original.
Problem: Regardless of what I do, I can not restore flash counter to 0. Triangle Away will always leave it at 1. Kies refuses to deal with the firmware as it considers it to be a custom. I have tried several guides on the net, but no luck.
I read somewhere that you might have to download your original firmware in order to be able to reset the counter. When I call *#1234# at this point I get:
AP: N7100XXDMB2
CP: N7100DDDLK6
CSC: N7100OXXDMB1
This is Finland (belonging to Nordic countries). What firmware do you recommend me to restore? I have googled but not found any firmare with all of AP, CP and CSC the same.
What would be the best way for me to restore the phone into original unrooted state?
i m in the same boat (i have a n7105 international), need to 'unroot and back to stock recovery and original firmware' as im returning it back for warranty.
if someone can tell me if the following are correct or not:
My current status:
n7105 - hong kong origin
-CWM recovery & on a custom rom
1. so do i need to flash CWM recovery back to stock recover first?
2. do i need to use triangle away to reset counter to the lowest (lowest is 1 i think, i could never get it to 0)
3. use the 'unroot' option from SU or from Exyno?
4. then do i flash latest stock rom (for my phone origin) via odin?

I am on the exact same rom and this is what I did (this is my version tho, thus follow the steps closely):
-1 Reflashed the N7100XXDMA6 Rom again so that the phone will be unrooted.
-2: Download and flash via odin CF_auto root by chainfire (your phone should be stock but rooted now).
-3: Boot up, download and install Triangle away and run it.
-4: Once it reboots after you wipe the counter try to co straight to recovery mode, if youre not fast enough follow step 5.
-5: Start it up in recovery mode (volume up+home+power key).
-6: -wipe cache
-factory reset
-wipe cache.
7 Reboot the phone.
Note afaik resseting the counter only works on stock rooted kernels.

My quote from another thread. Just ignore the rom version, just use yours and it should do the trick
Thanks Matzone!!!

Hi, sorry if his question has been asked before.
I purchased a grey import note 2, I then flashed it with Omega custom rom and I didn't back up the original rom.
Is it possible to check the origin country of this note 2 so that I can look up for the correct stock firmware to flash back to stock rom??
I need to send it for warranty claim, therefore I need to restore to original, but not sure which stock rom should I flash.
Thanks in advanced.
You can flash any stock ROM preferebly from your contry and flash using odin from here
http://forum.xda-developers.com/showthread.php?t=1896696
If you want to flash original firmware which was came packed
open Kies - Tools - firmware upgrade and initialization
it will ask for your serial number (you can find in setting - about device) and flash according serial number. which will be latest for your device.
Wrong section.
Since note 2 doesn't have an international warranty, you will have to send it to the country you imported it from. So flash the firmware of that country.
Sent from my GT-N7100
One more thing to clear
you already have custom ROM, so before sending to warranty make sure your flash counter is reset to 'No'
Just flashing stock ROM won't work
Read post#3 of thread mentioned in my previous post for any details.

Hi dr.ketan,
I've done resetting flash counter to 'No'.
After using Kies 'firmware upgrade and initialization', providing the model and serial number, it has downloaded the firmware and restored it back to stock rom.
So does this mean that the firmware Kies flashes is the official stock rom that my phone should be running?
Thanks.
Yes, bcoz it flashes firmware according to serial number so it means it should use its record.

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
Sent from my GT-N7100 using xda app-developers app
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.
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.

Hmmm...thats what i am actually thinking as of now....but looking for easy alternative like if we get the flashable zip or something of this baseband i can just flash it without taking backup of ROM and reinstall the ROM etc.....
But am looking for a site where i can download these basebands....
i take it you are trying to update the modem/baseband ihere you go. Must be done thru odin.
http://forum.xda-developers.com/galaxy-s4-tmobile/general/foh3-modem-bin-mdl-bootloader-t3191094
IMPORTANT: DO NOT CHANGE THE BOOTLOADER unless u KNOW EXACLY what you are doing...changing bootloader to the wrong bootloader will brick your device and some modem packages conatin bootloader. so make sure that you are getting a ODIN file that only contains the modems and no bootloader!
if you wish to properly update the bootlaoder and baseband properly ....just ODIN the OFFICIAL samsung release for your device and then re-root and reinstall recovery and then your rom.

Perfect....I will use this one....
And on S4 you don't even need to root before flashing TWRP and your ROM of choice. Just double flash the stock release with ODIN, let it boot up and make sure all is well, go into Camera to let it see if it needs a firmware update (happens automatically first time you run stock camera app), and when satisfied your phone is good, go into download mode, take TWRP + whatever else you want.
