I think it is not possible to downgrade, because of the Knox bootloader, but wait for an expert answer.

Bad experience with KK 4.4.2 brasil
First, wi-fi not working. after 3 fw reinstall with odin and routed, everythink ok, but, I see battery dropping like crazy.
I decide to downgrade from TWRP ... I install 4.2.2 ML1 by Ladyslav.... all thinks OK, but the modem not changed... modem from KK.
I try to reinstall ML1 Modem with odin, and I loose my IMEI/modem not found ( and kernel error or locked ... not shure )

Hey...I downgraded from germany KK NE6 to Brazil UBUBNE2. I think brazil UBUBNE2 has knox 2.0. I need an expert to confirm this, if you have a look at download mode on any kk firmware you will find this on the second last line :: BOOTLOADER RP SWREV : 2
That is the same revision of knox bl on ububne2 brazil JB firmware. I downgraded from GER NE6 to BRAZIL UBUBNE2 and I confirm this works.
GOOD LUCK.
IMPORTANT :: I need experts and senior users to please have a look at what I mentioned above. Thanks.

Hi why you downgrade from NE6 to UBUBNE2 ? Battery ?
I guess that I9195XXUCNE6 will take only 24hours of battery life anf about Max 3:30 hours on display time.
Any tests ?

@heget
back then when i flashed kk firmwares the modem did not upgrade...it remained on ububne2. as a result of this i faced hell of a lot issues....i thought it was something wrong with the rom...later i realised the modem was at fault..then flashed it and it worked...right now i am on xxucnf7 deodexed stock kitkat...its superb..very good battery life..check out the "post battery results" thread in general section..u will find my report there..
here it is

You can flash an official firmware using Odin. Your custom recovery will automatically be replaced if you flash an official firmware.
Although you can flash a custom rom....:good:
Hit thanks if i helped you
There is no harm in upgrading to 4.3 but some user reported big problems like unable to make calls, or IMEI lost, also unable to downgrade to 4.1.2 mostly. Biggest problem is excessive battery drain, wifi disconnection and unable to connect to slow network. You might wait until an official firmware airs for your phone. Maybe thats bugs free. You might then need to flash stock 4.1.2 to get over the air (OTA) update. You might be informed that you have got an update, or you can browse sammobile.com and search the firmware portal for your country. If you need information just post it here. I suggest to stay at 4.1.2 4.3 isn't a major improvement...

Why don't you try flashing a custom roms? Check out ProBam ROM: http://forum.xda-developers.com/showthread.php?t=2336271
One of the best ROMs I have seen. Really fast and stable
You might need to re-root after flashing.
DON'T
My suggestions is:
Don't "DO" if you "NOT SURE"
Don't "TRY" if you "CAN'T TAKE RISK"

firmware change?

Jason, you are fine to flash any ROM as long as it is for your specific model e.g. N7105 (yours) and not for another model. Being on 4.1 you may find your current bootloader causes intermittent problems on a 4.3 ROM. There are two solutions, upgrade your bootloader to MJ5 prior to flashing 4.3 ROM or flash 4.3 ROM then flash drketan's wifi fix.
I also recommend NOT flashing from Sammobile, instead go to Android development forum here on XDA and select an appropriate ROM. That way the Knox feature present in latest 4.3 ROMs can be avoided.
I have deliberately not included links for you - instead read & read install instructions from the ROM thread of your choosing. You will be fine as long as you understand each step & all the terms & points mentioned in ROM thread.
Good luck

update by country?!

Hey Guys
I'm a Newbie in Android stuff
I've Got a Note 10.1 2014 edition today and I was under the impression that the KK 4.4.2 update has been rolled out for it. read about it and watched a couple of KK video reviews. but now I see that it was P605 the LTE version!
unfortunately I bought the 3G version SM-P601 with the Baseband version of : P601XXUBMJ8 supposed to be for UAE I guess! not sure...
I checked in the firmware section in samsung website and saw that for some P601 devices like Indian versions, the 4.4.2 update is out!
is it possible for me to get those on my device without having to root?! and if yes, how?!
tnx in advance
Did you try the ota update check on your tablet? What does it say? I had to run the update from my pc. You can try that too. If both oc this fails you can update via odin if you can get your hands on the update file ... Usually a zip file.
Sent from my X9006 using Tapatalk
yea, I checked on both PC an Tablet updates both said the firmware is up to date!
I can download the zip file for other basebands, but I'm afraid flashing that would cause problems...
anyone can guide me what to do?
and this is from samsung firmware website
I Guess I can download Indian or Chinese 4.4.2 but can I have it on my tab with odin with no problem?
Ok! I can't post the image!

DO NOT downgrade to 4.2.2 if you had a higher version. (I'm not sure about CM though)
Download the 4.4.2 version and flash that.

Most probably... be sure to download the right firmware for your phone.

Flashing with different region firmware.

Hi guys, I have Galaxy Note 10.1 SM-P605. My one is most likely a Malaysian variant. Baseband version: P605XXUCOE1. I still haven't got the lollipop update on this variant. Now kinda planning to flash it with the Finland version. So I have some questions here before I do...
1. Will there be any sort of problem because of different baseband/ region?
2. Will I have to face any issue with knox or official OTA updates in future?
Thanks in advance.= :fingers-crossed:
I can only answer half of your questions, as my device is rooted, so i don't get official updates anyway. Flashing a different region firmware never caused me any troubles, not on my 10.1, or my Galaxy Note4, so it won't affect the functionality of your device.
As for Knox, it will trip Knox as you are flashing a kernel not for the same region...
It may just bootloop. Make sure you have a stock rom to go back to, mind you this may not work if the bootloader is upgraded to a newer version, say KK to L or L to MM....

Glad to know man, btw I am having only 1 problem that is it's not showing my operator's name on lock screen or in connection settings, instead it's showing the 5 digit number code of my operator. Thats not a major issue I guess, must be some conflict with regions.
