Nope, it will trigger Knox....

any idea how this behaves if you did not upgrade the bootloader files? (update with custom created odin tar)
aka could you downgrade if you still have old (MI7) bootloader?

Bootloader

Why all the people is obsesed in downgrade? This only will void ur warranty KNOX 0x1. Having new bootloader (android 4.4.2) and flashing old bootloader ****s ur phone, semibrick or future problems (battery cuts, sound lost, calls problems, no network registered). The unique solution u have is flash again 4.4.2. Im tired of write this pffff

Last Stock Rom without knox bootloader

CAn someone share with me last Stock Rom without knox bootloader?
The Stock Rom rooted with old bootloader would be great.
I still refuse to upgrade to bootloader with knox

You can grab any 4.2.2 formware from sammobile. Those shouldn't have knox in the bootloader.

That isn't correct.
Android 4.2.2 MH1 is the first firmware with all the Knox stuff, including the bootloader. 4.2.2 MGA is the latest firmware without Knox

Okay, sry it seems that I was a little bit wrong, the MGG build is the first 4.2.2 version with the new knox bootloader, but it is still correct that MGA is the last build with the Knox free one.
On my german sources they told that MH1 build is the first Knox version but however. Take a look at this

Knox has been introduced in Oct 2013 along with 4.3 bootloader (as far as i can remenber! one year old.....)
So your request is to come back to a 4.2.2 rom version, why? just to avoid Knox? OK I understand
But In my view you have better to flash a recent 4.4 CUSTOM rom that will preserve your legacy bootloader and will offer all the upto date features. They are many available in the dev section.
Custom Roms do not modify the boot section , so no risk to become knox pointed.
Thanks to Darker Times for his links.

Till now there is no such method to have root without tripping Knox in Lollipop,
You can update from kitkat to lollipop using Mobile ODIN and have root with Knox 0x0...

I updated the bootloader. If I downgrade will it also work with the new bootloader ?

Oh, I updated my Note using MOP and still running Kitkat Bootloader.
and I guess, Once bootloader is updated to Lollipop, then downgrade to Kitkat isn't possible.
If you try to downgrade you may get stuck in bootloop or null IMEI.

Well,
Apart from Bootloader, it is possible to downgrade from lollipop to kitkat without issues. (I can confirm because i have done this before).
My question was if I updated to lollipop and downgrade to kit kat again will the new bootloader trip knox to 0x1 when trying to root ?

No it won't trip Knox unless you flash something which is not officially signed from Samsung. Or unless you play with kernel and recovery.
@tahim. Download Samsung Phone Info app from playstore which shows all details of Note 3.
Thanks to @vndnguyen for this app.

Safe downgrade from 5.1.1 to 5.0.1?[UPDATED-MM]

Hello guys,
I want to try new update but,if I upgrade to 5.1.1 can I later go back to 5.0.1(stock one)?
And any bugs on 5.1.1?I read something abot fingerprint on lockscreen?it true? "
******************************************************
We got new update for N910C,is someone try to flash last bootloader and go back to COH4 or even 5.0.?
********************************************************
Ok now with MM 6.0.1 we can back to 5.1.1(CPB3) but no to 4.4.4

Dunno can you downgrade but, i had fingerprint problem and lag after lockscreen. Full wipe and deactivating smart lock(it was activated by default) seems to solve everything for now.
Pa:it was happening on mobile data.

Yes you can downgrade from 5.1.1 to 5.0.1
I installed 5.1.1 but returns to 5.0.1 with odin without problems

I used odin and firmware N910CXXU1BOE1 [Trinidad y Tobago] afert a hard reset and it's all. I have 5.0.1 in my note 4 n910c

I guess you need to do some steps to revert back to KK , you wanna downgrade from major firmware to another not simple update like 5.1.1 to 5.0.1
be sure what u doing or you may get in bootloop or something worse.

Don't think so.
it was said you cannot downgrade as some security fix.
samsung has put some bootloader and that will brick your phone.
Anyway guys from here can make some hope.

No major steps. Same steps regardless of OS version.

100% you can downgrade. Takes about 5 minutes if you already have the firmware.

Hm, so downgrading to 4.4.4 causes knox 0x1, but to 5.0.1 is warranty-safe?

Me too, I was rooted but found nothing great from doing so. Note 4 didn't run any better. So I had knox 1 anyhow.
5.1.1 is cool.
So yeah you can flash back to kk
