[Q] 4.4.2 Downgrade to 4.2.2, is this possible yet?

Hey guys, my question is there:
Its possible to downgrade from 4.4.2 to 4.2.2 ?
I have been reading alot of threads with similar question but i gives to many answer.
Im on a rooted 4.4.2 and i will just back to 4.2.2 because i will a !!completely!! Knox free rom and bootloader.
I dont care about the warrenty, my is run out.
I dont will not only a downgraded rom but also a downgraded bootloader.
When someone have trying a to downgrade from 4.4.2 to 4.2.2 please post here the result.
When a downgrade to 4.4.2 is not possible than which is the lowest firmware which i can flash?
Please try to keep the thread clear and give a usefull answer. Thank you guys
And please dont kill me for my english :good:

Once the bootloader has been upgraded to a Knox-enabled version, you cannot downgrade it. The ROM can be downgraded regardless of the bootloader, but running a Knox-free ROM with a Knox-enabled bootloader will result in a "Kernel is not SEAndroid Enforcing" message to appear on the splash screen every time the device is rebooted.

Okay too Bad...
A question more, i have been reading that a downgrade (Rom+Bootloader) is possible to 4.3, because there have the same Bootloader but just less aggressiv. Is that true?
When yes you can share a stock samsung rom 4.3 without knox?
Thank you for the answer

You can downgrade with a custom 4.2.2 rom. You just need to look for one.

Okay that i understand but can i downgrade the Bootloader to 4.3? Because there is similar to our one.

Can we use official ROM
Can we downgrade without using Custom ROM?
If we unpack Official tar ROM and remove the bootloader and modem of it and then repack it to tar.
Can that downgrade the Android version from 4.4.2 to 4.2.2?
Or it is not working?

It's possible to downgrade to stock 4.2.2 but a custom kernel such as KT-SGS4 will probably be needed to get the WiFi working.

Simply reinstalling the 4.2.2 modem files using Odin should be sufficient to get the WiFi working. No need of a custom kernel. It is also possible to downgrade the ROM without going through the routine of unpacking and repacking the ROM. Simply flash it through Odin, although you'd need to flash the modem files a second time to get the radios fully functional, as previously mentioned. Just be aware that the bootloader will not change, so every time you boot the 4.2.2 ROM with the Knox-enabled bootloader you will get a message on the splash screen about the kernel not being in enforcing mode.

I have trying this:
I take a orginal XXUBMF8 4.2.2 delete inside the zip bootloader and some other files repack back to .tar
Flash it all fine but then the error, the software is not authorized and on the top secure fail: kernel.
I tried flash a custom 4.2.2 kernel through odin but the same result.
My DL Modus look so: https://dl.dropboxusercontent.com/u/93311676/DSC_0014.JPG
Now i get back to 4.4.2 GNG8

[Q] rooting/to Downgrade unrooted LP S4 i9505, needing Stock KK Rom !?

Hi guys, i am doing this for a friend, hes on offial 5.0.1 LP accidentally updated it and he doesnt like it.
we need to root it and then downgrade Bootloader and Modem then flash a Stock based ROM yes !?
i have fetched latest KK modem/BL from a thread on xda , one with WiFi fix supposedly.. and the latest KK BL as well.
but i cant find a Flashable Stock KitKat Rom anywhere.. can someone help me with this please !?
and maybe link me to the stock Modem/BL as well.. cause i dont wanna brick his phone.
for now i have only Rooted it with AutoRoot.

You don't need to root it in order to be able to downgrade. You might even trip Knox in the process, so you're on the safer side if you don't do that. But as you have probably already done that, you could back EFS up using EFS Professional or terminal, just in case it gets corrupted during flashing.
I'm not completely sure about the downgrade process and what it takes not to brick your I9505, but you can find stock KitKat firmwares (flashable in Odin) here and here. There are some stock KitKat firmwares here as well, but some of them are offline. You can find some firmwares at SamMobile too, but you will probably need to pay to download from there.
Some pre-Lollipop modems can be found here, some more modems and bootloaders here.

[N910F] Downgrade from POF2 to ANK5?

Is it possible to downgrade the N910F from Lollipop (POF2) to KitKat (ANK5)?
YES, IT IS POSSIBLE.
Before yesterday I've never used KitKat on my Note4.. When I bought the phone I had no time to try it (KitKat) because I've straight rooted it and flashed a Lollipop based ROM.
Then yesterday I wanted to try a KitKat based ROM and I've lost about 30/40min looking in the forum for the answer to the question Is it possible to downgrade the N910F from Lollipop (POF2 or whatever) to KitKat (ANK5)?
I could not find a proper answer.. there was this BOF5 bootloader can not be downgraded but it was always in a "strange contest" and it did not convinced me.. after 30/40min I said ***k *t and I just performed a full wipe from TWRP, flashed ANK5 modem and bootloader via ODIN, and installed the KitKat ROM from TWRP.
Sorry for the Question/Answer but this thread may will help someone to save time.
P.S.: My KitKat adventure lasted only 10min... It looked ugly to my eyes! Went back on POF2 and now trying out AICP

When you flashed that lollipop-based rom, that was a custom rom I assume? Did it contain a bootloader? Maybe you were still on the KitKat bootloader.

Yes, it was a custom ROM. No, it didn't contain bootloader. No, I wasn't on the KitKat bootloader, for sure my bootloader was POF2. Trust me if I tell you that before the KitKat ROM I've flashed too many Lollipop ROMs with many Lollipop bootloaders.

You need wipe/clean data and then flash ROM which you were trying. If you want to upgrade baseband or modem then you could also flash stock rom. I was in a similar situation and I needed to wipe data factory reset before i could install custom rom

flashing from lollipop to kitkat custom rom?

hi guys, i have flashed android 5.0 stock with odin to my n9005 and then got recovery mode on my phone TWRP and flashed a couple of android 5.0 roms.. now im wondering if im able to go to kitkat (x-note) rom without any problems... my phone bootloader modem n stufs etcs are in lollipop's now as i used odin to upgrade it last time.

Yes you can go back to kitkat just flash kitkat firmware with odin and that's all

Flashing a custom ROM should not touch your installed bootloader or modem.
Try flashing a custom ROM with your existing bootloader and modem. If it doesn't work properly, then consider changing the bootloader and modem.
