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.

Hello guys,
I have a note 3 n9005 model I decided to update my firmware with the recently released Polish lolipop firmware using odin and everything was great, after 3 days of use it appears that lollipop is a bit laggy and sometimes hangs for a while that's why I want downgrade to Kitkat, also i would like to mention that I have updated the bootloader while flashing by ticking the update bootloader button in odin.
Now what's the possibilities of using odin again to downgrade to official Kitkat using one package file?
If not possible what if I have flashed a separate bootloader file then used odin with official kitkat is that even possible ?
Furthermore, I was thinking about rooting my Lollipop then flash a custom recovery and then wipe data and cache to install a flashable custom Kitkat.
My request is that I need someone experienced to confirm with me on what should I do without risking bricking my N3, I'm going to die with it if it's bricked
Thanks in advance for your support.
Regards,
Where is the great supporters ? Not even a one reply :crying:

Lolipop is rootable search the forum, and this not my question actually I'm asking what if i rooted it then installed a cwm based recovery to flash Kitkat, will this work or I'm risking for a brick or bootloop or any other problems?
If you have the right answer please answer it with prove, if not this thread is not for bored ppl that don't provide any fruitful feedback.

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.

Now i get back to 4.4.2 GNG8
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.
I'm trying to do this but i fail in every action at odin with this SW rev. check fail. device 2 binary 1 in my SM-N910C and in odin its fail... ( i gets this after recovering my phone at kies after a bootloop )

Hi,
I have experience with the Canadian S4 I337M, currently running custom Validus ROM 5.1.1, originally was on TouchWiz 4.4.2;
I have altough a question that seems quite.. debated, did looked around I can't find a definitive answer and know who I should trust. I wonder if options changed in 2015 rather than 2013 when KNOX was still new.
Out of simple curiosity (I will not attempt it, risky, probably useless and I'm running 5.1.1 anyway): I keep reading that it's impossible to downgrade the S4 to 4.2.2, due to the KNOX bootloader on 4.3 / 4.4, I understand that you cannot downgrade below 4.3 which is the "new" KNOX bootloader.
1. I'm simply curious: On the I337M, what happens if you grab the stock 4.2.2 firmware and flash it with Odin anyway, considering I'm on 4.4 ? My guess, if I'm correct, Odin detect the bootloader version right away and says "FAIL". Correct?
2. I used to think it was possible to downgrade from 4.4 to 4.3, since 4.3 has the KNOX bootloader as well. Is this possible anyway, or will Odin fail (Not going to try it, not worth it)? Considering what I've read just today, 4.4 is also a new bootloader. In any case, since that 4.4 bootloader cannot be downgraded (I guess?), there is no way to downgrade from 4.4 to stock 4.3 either? Odin will show "FAIL" ?
3. Is there any other way to downgrade it anyway? I understand that KNOX 0x1 remain irreversible yet, and to my knowledge, it's impossible to dowgrade to 4.2.2 (Or even 4.3?), but I've been reading that it was possible to downgrade if the bootloader is excluded from the TAR archive, make sense to me, but is that true, was that patched? Should I recompile an ODIN package excluding the bootloader, is that how it's done (Too dangerous, not trying it)? Or maybe by using Mobile Odin / FlashFire, downgrading from 4.4 to 4.3 / 4.2 can be acheived, if the bootloader is left untouched? What happens if we try it anyways? Odin fail, or device does boot but doesn't get past Samsung boot logo?
I'm just wondering, and quite confused by the different opinions that were shared. Remember this is for the Canadian I337M variant.
Thanks for confirming, appreciate!
Hi, I meant SGH-i337 in the title.
I beleive I posted this in the completely wrong phone section last time, so I am posting this here.
My device model is the SGH-I337. I downloaded Odin version 3.12.3, downloaded the official drivers for the Samsung S4 USB, but I can't seem to find stock Lollipop 5.0.1. SamMobile only gives the 4.x versions for some reason. I started following the below link for a method to at least flash an older firmware to my phone, but I want to flash stock Lollipop. Is there even a way to get Lollipop back without root?
https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078
I was able to downgrade, but I still need an official stock 5.0.1 firmware. My virus protection says towelroot is a virus, so I don't want to go that route. If I do an OTA upgrade after I flash the old firmware from the above link, will it brick my phone? It's rootable NB1 ROM. I already tried to install the stock 4.x firmware from SamMobile, but that doesn't work, so it seems I need stock Lollipop.
AT&T never released a stock lollipop firmware that can be flashed with Odin. All at&t updates were released ota.

Hi I am running goldeneye custom rom on my i-337 5.0.1 with ok2 kernel. If you go to that forum thread in development, you will find very detailed instructions to get att s4 to 5.0.1 stock. As a side note I can assure you if you just download towel root on your phone, install and run there is no virus of any sort. Make sure you download from towelroot .com
On second look through I don't think there is stock 5.0.1 using safestrap....
