Hi there,

I've got my second N7100 , and it came with the JellyBean 4.3.

I recall the old good times, when the JB 4.1.2 was definitely faster....
The new mobile has never been rooted or upgraded (Knox 0x0), and I was wondering if there is any chance to succesfully downgrade it. I just did the same with a Galaxy S3 with full success and, even f I know they are two completely different devices, it lighted my hopes to do something similar with the Note too, hopefully without increasing the knox counter.

Some info from the current firm (4.3):
AP: N7100XXUEMK9
CP: N7100XXUEMJ9
CSC: N7100ITVEMK2

Downloaded firmware (4.1.2)
N7100XXDME6_N7100ITVDMF1_ITV

(it's an Italian device).

Any info, hope, recommendation?

Thanks!

As far as i'm aware there is currently no hope of downgrading the Note 2 from 4.3 Knox has it locked up tight.
I hunted for a long time after I was seriously underwhelmed by 4.3 and the best I could find was saferoot to root with out tripping knox.
But then you have the problem that The 4.3 "upgrade" locked the bootloader down even tighter so you can't install a custom recovery to flash a 4.1.2 based rom.

All that said there has been some amazing work done by Hashcode and Beastmode I think, who have got Safestrap into a working beta for at least the Verizon Note2. This means you can flash 4.3 based roms for now. (but only the verizon note2 just now...I think)
So there is a bit of hope. I'm running a non network branded Note2 so keeping my eye on how things are going over in the Verizon camp.

4.4.2 is available...why not flash that instead? Its a definite improvement over 4.3.

I'm tempted but the only way to root 4.4.2 just now WILL trip KNOX and I'm not psyched about that.
Also there's a good chance that the 4.4.2 boot loader is locked down tighter yet and we'll have to wait even longer for a work around.
I "upgraded" as soon as 4.3 was available only to find that I'd shot myself in the foot because of the change to the boot loader.
This is just personal opinion...I don't have any facts to back up the guess that the 4.4.2 boot loader is trouble...but I'm waiting for now.

Good point: I have the same feeling and fear at the same time.

Before flashing the 4.4.2 I am waiting to read some positive comments, not olny based on a "first approach" enthusiasm (please let me pass this expression).
I was wondering if any Samsung service center can do the dowgrade, perhaps using some internal software / any ther things that they can use and it is not available for us, "mere mortals" ...

Hmm it's probably something that they COULD do but I don't think that they WOULD do it.
It depends on if they have a "point and shoot" Samsung flashing tool or if they could choose what version of bootloader and firmware to use separately.
Honestly I'm guessing though.

Don't flash anything you are not absolutely 250 % sure and wait patiently. Going up to 4.4x might block you even more without a chance to downgrade at all. Don't believe everything you read 4.4x it's a treat. .kit kat remember.
