Dis yu made a nandroid backup?, or an OFS backup?, couse the probems is the knox app and if yu¿ou have your backup you always can do a restore, the problem is the bootloader. or you can reflash the mk4 rom.

i did not make a back up because i did not know that after update i would have problem with downgrade.this was a big mistake probably from me. after update i rooted my phone and now i can not downgrade to any other firmware except mk4. i just want to go back to mj5 or mi6 or anything else. i think dr ketan told something like this but only for mj5. have you got any other idea for mk4 my friend???because im ready to throw my phone from window....

I did this twice but still nothing. I guess that have to wait for someone of developers to find a way to throw knox warranty away to do after this whatever i want again. Thanks for your trying to help me my friend. But i still want to throw my phone from window

Do you have in download mode warranty void line and if so is it 0 or 1?
I think if you have warranty void line in download mode and it is 0/0 you should wait for a work arround or else you'll loose your warranty even if you flash an official rom (4.1.2 foe exemple) with odin because it will trigger your knox warranty counter!
Don't throw it out the window...it's a good phone
As i know if you flash to a stock rom early to the last version you can lost your IMEI and the problem here is precicely the bootloader and NFS directory, allways is necesary made a nandroid backup, As i read the only option is flash the Stock rom and then try recover the phone and still in MK4 rom, Sorry i don´t see anoter option.

Hi. Hey i flash the mk4 from sammobile and works perfect, but i find that wifi gets a little weak and some time you trhing to do something and a shild appears that says that weathever got block for the pho es safety.

Yes, its possible to rollback to previous version. Download the previous version of Stock ROM from sammobile and flash this ROM via Odin v3.07 then it will roll back to the previous version..
Hit thanks if my post is helpful.

No way to rollback into previous version, as no vendor supports downgrading . If u need your old software, just download Original stock firmware (definitely some older version :silly and reflash it with Odin as @Parth2187 mentioned:cyclops:
This is what I did. I had a nand bqckup of my 4.1.2 stock rooted rom.
1. Flashed 4.1.2 stock via Odin.
2. Root3d and flashed CWM recovery.
3. Once in recovery rolled back my original nand.
Please note if u end up in a boot loop. Make aure u go to stock recovery and do data/factory reset and wipe cache and u r good to go.
Hope helps. Worked foe me.

If you root your phone, you won't be able to receive OTA updates and it will void your warranty. If you unroot you can get the OTA updates.
To root see this thread
If you want to unroot, see this thread.

I don't think a factory reset can unroot a device. I am not pretty sure about this, if u are successful in that, its okay. But factory reset just formats the internal SD card. It wont do anything with /Root directory. When you are rooting a phone, we flash SU to the /root directory.. Then how come a factory reset can unroot a device. Probably impossible! Correct me if i am wrong

+1...factory reset does not unroot...........flashing stock rom through odin and using traingle away ( not in that order ) would unroot the device..we are priviledged that our device has all prequisites for rooting and unrooting...
I tried flashing the old rom with odin but it gives some error :/ maybe my firmware has sm problem :|

Not 100% sure but looks like you flashed with reactivation lock on... Only way I know is to flash original stock rom but you may have flashed the new Kitkat bootloader.
You will need the Kitkat rom for your region to fix...

Mate, flash stock JB... Don't throw a new OS into the mix... It's easier if you use what you have 1st, fix it, then upgrade...

Dear friend ... Seems your skilled about this tablet ... So maybe you can help me with my problem :
I were having problem with my nand memory so I managed to flash a ROM with having the " Wipe NAND all " ticked in Odin and after that I found that the phone wont boot so I thought it might be from the bootloader and updated the bootloader to KK and now I can't get my tablet to even boot android and also I can't mount /data ... is there any solution for me ? ... is there any way to get that JB firmware flashed on my tab ? ... is there any way to even boot the android to pick my files ? ... thanks in advance ...

Your problem is that you have flashed Xkat ROm without first flashing a stock 4.4.2 as clearly mentioned in the installation instructions of the ROM.
I think that now you have to try to flash A Stock 4.4.2 with Odin to get your tablet working again.
Well ...

Dear all,
Well I dont know where to start. But here is what happened with my N7100 Note 2.
I was on the latest 4.4.2, the phone restarted suddenly one day and it just dont boot stuck at samsung logo,
flashed the 4.4.2 stock from sammobile. and it worked fine everything was perfect for a week, till it happened again
flashed the same rom. and here is where the trouble begins.
The IMEI changed to generic 00499XXX.., Serial No: 000000
i managed to downgrade to 4.1.2 with mobile odin, flashed a lot of stocks and customs as well. And after a very hard work for a week i manage to get back my IMEI and serial number back, now I backed up my EFS learned my lesson
Now i flashed the stock rom 4.1.1, phone is unlocked. cant make calls, or sms or data internet.
Now I have service: out of service, Bluetooth address: unavailable (while its in the efs folder the mac is in the file), Device status modified, And when I connect it to USB it wont recognize the phone until I have to dial *#7284# and change USB from modem to PDA, then save and reset. (EVERYTIME) I need a permanent fix as well for that.
Please I need help with those as i cant make my phone work.
Thanks and regards,
Mohamed Selim.
First and most important:
If you ever were on stock 4.4.x you can't downgrade to 4.1.x because of knoxed bootloader.
What you did with mobile odin was no real downgrade cause your bootloader wasn't touched.
Don't try to flash firmware beyond your current bootloader version.
Install Samsung Phone Info app from play store and look for actual bootloader version.

As I said before: YOU DID NOT DOWNGRADE firmware to 4.1.2 with Mobile Odin, check with Info app from Samsung:
You will find bootloader between *ND3 and *NI1 and all are 4.4.2 KitKat
So, whatever firmware you try to flash under 4.4.2 is supposed to fail.

Mobile Odin does everything but doesn't flash bootloader so it is like flashing a custom rom which also doesn't contain bootloader.
PC Odin flashes complete firmware, so this is the only way to really up- or downgrade. Hope you understand the difference.
The only solution I see for you is to concentrate on 4.4.2 equal or up your actual bootloader version.

I really want to help you out and I assure you that I know what I am talking about (take a look into my signature with stock roms and bootloaders).
There is indeed no solution on 4.1.1 and the screenshot doesn't show bootloader version. To believe what I say try to find out what BL version you are on. If it shows XXUFND3 up to XXUFNI1 you have the proof.

XXUFND3 was the first KitKat firmware for N7100 and yours was the second.
Three options:
1) Flash firmware using PC Odin at least ND4, maybe better NE1 or up
2) Flash through recovery any stock KitKat custom rom provided by wesamothman, cosmyndemeter or me
3) Flash through recovery any KitKat custom rom you like from development section here
4.3 custom roms may work also, but not 100% sure.
Beyond 4.3 I wouldn't recommend.

Best and fastest one is XXUFNI1, NH2 and NG3 aren't bad either.
Do a clean installation (factory reset) and after setup device go back into recovery to flash SuperSu.zip.:highfive:

You can get a JB version at http://www.sammobile.com/firmware and flash it with Odin.

First I try with a stoc 4.3 but no succes with odin.
But succeded downgrade with stoc 4.1.2 from SD card.
It's not possible to downgrade, because there's new version of Knox that will block any downgrade. It's the same as normal Note 3
Can anyone please tell me a method to downgrade my device ..

Yes! there may or may not be difference in modem/baseband, but bootloader needs to be compatbible, hence flashed for 4.3 before flashing 4.3 itself
yes
You are able to downgrade , but only if the 4.3 zip has newer build date than your current installed 4.4
See this post
