A Few Questions regarding unlocks

hi guys i have a Rogers sgh-i317m and recently downgraded it from 4.1.2 to 4.1.1 and got it to work with Wind Mobile, I now want to upgrade it to 4.3 , if doing so will it kill my unlock with Wind Moible? and if not should i use odin to upgrade it or over the air?
My Last question is in regards to a thread i saw somewhere that said you cannot downgrade your sgh-i317 to 4.1.1 once you are on 4.3 , is that true? thanks alot
Unlock is permanent and you can downgrade.
So far I have read is you can not downgrade from 4.3
You can downgrade. Make a nandroid.

[Q] Can I downgrade to try Saferoot?

I came across this thread recently (I own an S4 as well) http://forum.xda-developers.com/showthread.php?t=2565758 and I wondered whether anyone had tried this approach on a Note 10.1 2014.
Unfortunately, I recently upgraded to Kitkat and I'm now running ND2 so it won't work for me. Can anyone tell me what the earliest ROM version I can downgrade to using Odin (if I can downgrade at all) without blowing the Knox fuse.

10.1 unroot

I'm running 4.2.2 on my 10.1 and it is rooted.
It was done long ago and I really do not need the device being rooted anymore.
Not sure how to unroot it so I can upgrade to 4.42.
It might have been posted but I couldn't find it.
Help appreciated.

Beware that some of us believe that upgrading to 4.4.2 via OTA or Kies or installing Stock 4.4.2 as they come is unsafe!!!
New stock 4.4.2 comes with new bootloaders!!
So for us the safest way to upgrade is use one of the many Rom develop in our forrum. Yes I understand many think the opposite,safest is to stick with Samsung Stock as it come from factory. It is up to you.
A few had claim that after you go back to 4.2.2 Official Stock, their programing counter had clear and they in fact go OTA or Kies to upgrade to 4.4.2. Personally I do not know. I do not use Kies.
But here is an example of such Claim:
Samsung Galaxy Tab 3 > Galaxy Tab 3 General > KitKat Update official for GT-P5210 available => http://forum.xda-developers.com/galaxy-tab-3/general/kitkat-update-official-gt-p5210-t2871073
Good luck with your upgrade, I hope nothing happens with those new bootloaders in the future. Who knows maybe you will not be able to clear your counter again! I do not know I am just kidding.
Thanks, that worked, now I am on 4.4.2.
Just a crazy question, what if I want to go back to 4.2.2, can it be done?

You have not said what type of TAB3 10 you have. 3G, wifi or 4G. Nor said what procedure you follow. Ota, Kies or one of the roms develop here.
I do not know if installing 4.4.2 with OTA or Kies can prevent you to go back.
In my case I use 4.4.2 Pimpdroid 3Beta. I found it smooth and nice. But I got upset with 4.4.2 limitations and went back to 4.2.2 with stock 4.2.2. Without any problems.

Unlock KNOX to allow downgrade from 4.4.2 stock to 4.3 stock?

I've read up in a lot of places about my issue of downgrading from 4.4.2 to 4.3. I'm looking to downgrade back to 4.3 because rooting 4.4.2 isn't available yet for my model but for 4.3 it is. Also flash doesn't seem to work in 4.4.2 either. It seems that KNOX has something to do with preventing you flashing older Samsung official versions of Android or something. I tried flashing 4.3 via Odin 3.07 without sucess, but mysteriously the 4.1.1 rom I got from Stockroms.net works but it appears as custom instead of "Samsung Offical". Anyways looking for away to unlock KNOX to allow downgrades.
PS My note 2 is a Canadian Note 2 (SGH-i317M) from Bell(BMC) I posted here under AT&T Due the similar version number and no Bell Note 2 forum.

How to downgrade from 4.4.1 to 4.1/4.3?

How to downgrade from 4.4.1 OEM to 4.3? OEM, no rooting really needed, I tried to go to 4.1.1 first and then flash to 4.3 but it keeps the 4.4.1 bootloader so the charging does not work when the phone is off...
There were no responses for almost 3.5 months however I keep hoping!
I know Note 2 is almost antique, however need to downgrade 4.4.1 bootloader UCUCNJ1 to original 4.1.2 LJ2 or 4.3 as the latest. I was able to go down to 4.1.1 but bootloader remained the same new one. It's an older phone, so there should be a way to get this done.
Maybe there is a way to make bootloader UCUCNJ1 work properly with 4.1 or 4.3?
I believe the bootloader on the i317 is locked and cannot be downgraded unlike the i317m.
Thanks!
All I need is 4.1 or 4.3 even with late NJ1 bootloader I have, as long as the phone would charge while being off
Need SOME advise, there must be a way of doing this.
I know of no way to unlock the bootloader to downgrade it to 4.1 or 4.3.
This is the picture of the real phone, OS 4.1.2 with NE5, correct?
I'd be fine with late NJ1 bootloader working properly with OS 4.1....
I was able to go down to 4.1.1 using this method http://forum.xda-developers.com/showthread.php?t=2618447 sadly NJ1 bootloader did not allow the phone to charge properly while off...
The phone can have a rom and bootloader that don't match but it is unlikely that an older rom will work properly with a newer bootloader.
Have you tried flashing the latest rom to see if that solves the issue? I don't have the 317, I have the 317m and I'm not sure if nj1 is the latest rom for the 317.

Yes I'm back to 4.4.1 everything works as it should (charges while the phone is off without locking the phone up), but I NEED to downgrade to 4.1 or 4.3 as the latest. Getting down from 4.4 to 4.1 or 4.3 is the whole point. The phone is so old, it's hard to believe that my question does not have a positive answer
I see people downgrade from 4.3 bootloader down to 4.1 no problem http://forum.xda-developers.com/showthread.php?t=2502464
I understand your frustration but 4.3 to 4.1 was possible, but 4.4.2 to 4.1 is not.

4.4.2->4.3 would work for me - is it possible?
Downgrading the bootloader to 4.3 from 4.4.2 is not possible based on my everything I have read and heard. I have never come across a post to indicate that the downgrade was successful.
Being in Canada, the phone I had was the i317m which, if I recall correctly, did have a downgradable bootloader. It's been a couple of years since I had a Note 2.
So we can make it official: on AT&T SGH-I317 there is no way to downgrade Android 4.4.1 to any earlier version.
As far as I am aware, once the AT&T Note 2 is on stock 4.4.2, there is no way to downgrade everything to 4.3, although there may be ways to downgrade parts of ROM/modem to 4.3 but not the bootloader.
