Hello!!!
I have one question, it is possible to go back to 4.2 or 4.3 after install 4.4.2?
If yes, how can I do this?

No.

It is possible, but it will change your KNOX status to 0x1 and this could void your warranty.

[Q] Bought used 9506. What are my options (root)

I have bought a used S4+ i9506. It has been updated to stock 4.3 and knox status is 0x0.
I see that there's very little development around this device. I have a few questions.
What are my options if I want to root? Are there any?
If so, are there any way of rooting it without tripping knox?
Anyone know if an official 4.4.2 is on it's way? Norwegian phone with csc NEE.
1. Kingo app -> HERE. It doesn't void ur warranty (KNOX: 0x0)
2. NEE doesn't have android 4.2.2 still (Pic attached)

[Q] [GT-I9506] Is it possible to downgrade 4.4.2 to 4.3 for towelroot

So is it possible? I have seen guides for this kind of thing but it only had link for kernel and that was for i9505 not i9506 so i'm curious how you can root this model without tripping knox, i'm really confused, any help will be accepted, thanks.
I think that you can, but Knox will be tripped

In general custom roms doesn't have knox. But if install a custom rom the knox counter will be triggered and your warranty will be void. And it doesn't exist any official Samsung firmware without know. Any firmware without know isn't a official firmware anymore.
I hope this helped you to understand.

[GT-I9505] CUSTOM ROM that WILL NOT TRIGGER KNOX WARRANTY BIT 0x0 to 0x1

Do you have any working Custom ROMs that will not trigger Knox Warranty Bit 0x0 to 0x1?
Or rather any working suggestions to avoid bootloader to be locked when flashing non-knox enabled firmware?
Please Confirm if the following were TRUE or NOT.
SITUATION 1:
Official Lollipop 5.0.1 to Official Kitkat 4.4.2
KNOX will retain at 0x0
SITUATION 2:
Official Kitkat 4.4.2 to Official Lollipop 5.0.1
KNOX will retain at 0x0
SITUATION 3:
Official Kikat 4.4.2 to Official Jellybean 4.3
KNOX will retain at 0x0
SITUATION 4:
Official Jellybean 4.3 to Official Kitkat 4.4.2
KNOX will retain 0x0
SITUATION 5:
Official Jellybean 4.3 to Official Kitkat4.4.2
KNOX will retain at 0x0
SITUATION 6:
Official JB 4.2 to Official JB 4.3/KK 4.4/LP 5.0.1
KNOX will retain at 0x0
SITUATION 7:
Official JB 4.3/KK 4.4/LP 5.0.1 to Official JB 4.2
KNOX will issue at 0x1
Downgrading to JB 4.2 will restrict user to upgrade to higher Android Version.
But User can flash Custom ROM all they want?
The bootloader isn't locked by flashing any kind of firmware.
Your device either comes with a locked bootloader or an unlocked bootloader. Verizon and AT&T phones usually have a locked bootloader.
You can find some info here.
But it's seems a lot of hassle and isn't really worth it unless you are using KNOX or count on the warranty.
