Hey guys i have a galaxy s4 19500 running android 4.4.2 kitkat ( argentian (aro) firmware )
My phone was recently on 5.0.1 lollipop (indian ) version and i downgraded to 4.4.2 argentian firmware following a thread here on xda
I was wondering if a downgraded to 4.2.2 JELLYBEAN was possible ?
I mean i know it's super messy becuase of knox but if we take all the precautions like backing up efs partition then can the downgrade be done ?
I really think that jellybean is the perfect firmware for s4 and kitkat and lollipop have both made my s4 experience only worse
It would be awesome if i could go back to 4.2.2 jellybean and enjoy my old device
If you downgrade to 4.2.2 you will brick the device. Since new bootloader( version of Android 4.4.2 i think), you are not able to install 4.2.2 without brick.
@sgalchev: Not true at all. It is possible to replace 4.4.2 with 4.2.2 as I have done it in order to resolve issues I had with my S4. What ends up happening after doing the downgrade is that upon every boot and upon every trip into the recovery you will get a notification that the kernel or recovery is not SEAndroid enforcing. Other than that everything works normally.
Now, downgrading from 5.0.1 to 4.2.2 may be a completely different matter, but I suspect it too is possible.
Yea, shure, but you can't do it without ticking the Knox flag[emoji6] Goodbye warranty...

Hey man it feels awesome to know that it is possible to do can you please give detailed explanation of how you did it
I would really like to do it no matter how much hard or risky it is and i have already downgraded from 5.0.1 to 4.4.2 now i just need to downgrade to stock out of the box jellybean software
@sgalchev: Changing the goalposts? You flat out stated the OP would brick his S4 if he attempted to downgrade. When called on it, you switched your argument to tripping the Knox flag. As he mentioned in his latest post, he had downgraded to Android 4.4.2 from Android 5.0.1, so it's likely his Knox flag is already tripped. Even if it wasn't, I can't comfirm whether the Knox flag will get tripped as my Knox flag was tripped when I bought my I9505. Tripping the Knox flag != bricking the S4.
@tdssmarty16: Keep in mind that while everything worked, it took two flashes of the ROM to do it, and I only kept it on 4.2.2 long enough to verify that the hardware and firmware issues I was having were resolved. I then went back to 4.4.2. In downgrading to 4.2.2 I went to sammobile.com and downloaded the 4.2.2 firmware from them. Other than that, I simply treated it as if I was doing an upgrade through Odin. Unlike going from Android 5.0.1 to Android 4.4.2, going from 4.4.2 to 4.2.2 should be a piece of cake.

okay bro i will try to do it this way thanx for info
Hi I would appreciate alot if someone can teach me how to downgrade form 5.0 to 4.4.2 or at least 4.2.2 . I spent the whole day yesterday figuring out how to do it i'm not good with technology and I'm using a macbook. I'm using S4. Thank you.
Which model S4 do you have? Only certain models can be downgraded to 4.2.2.
Downgrade i9505

I downgraded my i9505 from 4.4.2 to 4.2.2 but had no sound so I went back to kitkat.It is possible to downgrade but I don't know is it possible to be fully functional.
I did it long enough to both check my SIM tray at the time, and to unlock the device. I wasn't getting any signal (expected), but I didn't check sound. I do suspect that if the 4.2.2 modem is flashed a second time everything would work. The only indicator that you were ever on anything higher would be the warning the bootloader pops up on every reboot about SELinux.
No sound,no wifi
I forgot first time to say wifi also didn't worked.I don't care for my warranty because flag was already tripped and now my device is older than 2 years so I can try some solution If someone has one.
anyone active here? it's not possible to downgrade to jelly bean anymore as the bootloader is locked to downgrade max at 4.4 as 4.2 will not work at all
if anyone has a ideea on how to do it (some people did it) i would be verry happy if you could share that info
I have not seen a post where someone running a 4.4.2 or 5.01 bootloader had successfully downgraded the bootloader to 4.2.2

Haven't played with custom rom for awhile as well as rooting/recovery.
Now that Samsung implemented Knox, I'm reading this is changing how to implement roms and upgrading/downgrading stock roms.
I am currently on MDJ from MG1 and did not want to go to 4.3 because of the full blown Knox implementation.
So my questions are:
1. Can I still downgrade from 4.3 to 4.2.2 (MDJ)? I read some in one thread you can but others you can't. Have to make sure which thread I read for I337 vs I337M which seem quite different. Reason is that I can still easily repair/modify stuff on MDJ firmware.
2. I am also considering installing Google Edition 4.4.2 ROM as I believe it does not have Knox. Can I easily revert back to 4.2.2 MDJ from a custom rom?
I've been reading for awhile and I can't seem to figure this out. Must be old age. TIA.

The safest thing to do is stay on a version without the knox bootloader. I know for sure I337 can't downgrade, and i think the bootloader isn't downgradeable but the system is or something for the I337M. I'm not sure, but either way the safest bet is to stay without the 4.3 bootloader. That way you can root and use recovery and flash without worrying about knox and you'll easily be able to revert from any custom ROM back to stock as long as you either keep a nandroid backup or the ODIN files for the firmware.

Yeah, I think I'll do that. I also understand the issue with Knox is tripping the counter voiding the warranty but I don't care about my warranty. Going to try Goldeneye when I get the chance or look at some 4.4 roms.
I don't know why Samsung or any other manufacturer just let corporate users enforce Knox or whatever and let the rest of the users alone.
its completely fine flashing custom roms with the 4.3 bootloader for us canadians. the only downside is, you will trip a knox flash counter, it cannot yet be reset. you only see this flash counter in download mode. AND if you have a non-official kernel, or recovery, you get a little yellow message in upper left corner during the first bootscreen.
BUT. if you do not upgrade to 4.3 modem, you will experience data drops (loss of signal randomly) with any custom 4.3 or 4.4 rom.
so you dont have to upgrade to 4.3 bootloaders, but you will need to get the modem, its around, if you are already on 4.3... just flash the phone as normal, you cant go back, but its not stopping you from going forward.
I have the bell smartphone protection plan, if i break the phone, they replace it, and dont care about custom software or booloader flash counters ect. So i dont care either.
For the modem, find a copy of MK6 modem assuming your in Canada, flash it through odin from your pc. If you get a fail, chances are you have a bad download (happened to me) download from a different source then. Before you flash any rom... root.... install custom recovery.... nand backup your current "stock but rooted rom" If you flash a 4.4 rom (not sure if this applies to 4.3) do a full wipe... System/cache/dalvic.... then factory reset... then flash.... I flashed 4.4 the first 2 times without wiping system and though the phone worked fine, data was inconsistant at times.....

I have a Bell S4 with Google Play Edition 4.4.2 running perfectly so far. I had an MDJ modem, and tried flashing many custom ROMs on it. All 4.3 ROMs worked fine, and only AOSP 4.4 ROMs also worked fine. The only problem was the GPE 4.4 ROMs that gave me constant signal drops. So I tried to upgrade my modem to MK6 to fix the issue. Even when I upgraded to Samsung's stock 4.3 through Odin, it still didn't upgrade my modem. I had to manually flash the modem in Odin to get it to upgrade successfully. Then I just flashed a GPE ROM and everything went well.
i new on android ... now i using galaxy note 2 ...
the problem phone is got super user ... what i know is my phone was root ...
can i unroot it ??? because i wanna upgrade it to kitkat if can ...
please someone help me ... new on android ...
which country firmware i need to download ???
will my phone brick if i download wrong firmware ???
If you want to unroot fully download triangle away to reset your counter and run it then uinstall superuser. That's pretty much it if you are on stock with stock recovery. If not you can flash stock through odin and it will be back to factory. There is a stock 4.4 prerooted 4.4.2 available which you could flash without needing to unroot

I know it might all sound too overwhelming cause that's how i felt when i was in your situation but reading a lot of threads and gaining as much knowledge i somehow understood what i needed to proceed ahead and flash newer custom ROMS,since you are 4.1.2 and rooted in order to upgrade to 4.3 or 4.4.2 custom roms you don't need to unroot or use triangle away,all you need is custom recovery (philz touch 6.26.0 or twrp 2.7.0) ,you need mj5 bootloader(i'll explain about bootloader in detail below ) and last but not the least backup your current 4.1.2 stock rooted ROM as well as EFS partition.You can visit dr ketan's thread on how to back up your efs incase your imei goes corrupted chances are rare but it has happened with people so backing up EFS is must.Now after you have taken care of 4.1.2 ,you can proceed with flashing a custom ROM,since you want to flash 4.4.2 there are several deknoxed,dedoxed and pre rooted ROM's available by developers and they are just like stock samsung ROM.
Now comes the tricky part and it depends on an individual how he goes about bootloader part. Since you are on 4.1.2 stock rooted ROM your bootloader is outdated,there are few 4.3 Jellybean bootloaders but MJ5 bootloader is the BEST cause it's deknoxed ,meaning it won't void your warranty so even if you upgrade to 4.4.2 you can always go back to 4.1.2 stock ROM ,unroot your phone ,reset the flash counter via triangle away and then take it to service center.If you flash MK4/MJ9 bootloaders which is built in if you officially upgrade to 4.3 you'll be KNOX ,so when you root your phone knox will be triggered and warranty will be null,there's NO WAY currently to reset knox once its triggered. There are no benefits of knox but samsung has its own theory of implementing it for security purposes.Also one cannot downgrade back to 4.1.2 if they flash a knox bootloader you'll be stuck on 4.3 or 4.4 roms
So let's say you flash mj5 bootloader ,then flash the kitkat ROM from one of the links available on xda only draw back being on 4.3 jellybean bootloader (whether its mj5/mk4/mj9) you cannot charge your phone when turned off when on samsung touch wiz kitkat ROM.Kitkat bootloader is available but it's KNOXED which as stated earlier knoxed bootloader will void your warranty but you'd be able to charge your phone when turned off.
I know this is a lot of information at once for you to understand but main thing you should worry about is backing up EFS partition and which bootloader you choose, once you take care of those two things, ROM flashing is easy if you follow the correct steps on how to flash it (mainly making sure you clean your internal memory of phone clean).I am on mj5 bootloader and just this morning i flashed 4.4.2 ROM and everything is running smoothly,no fc no bootloop nothing.
If some one can help me with my troubles it will be greatly appreciated, I recently purchased a SG Note 3 Brand new sealed and brought it to a store to unlock and the person tried and said this phone was new and was not able to be software unlocked unless by code which was more expensive so i declined.While waiting in the mean time i started reading xda forums for info on rooting my note 3,Where i discovered Canadian SM-900W8's weren't locked to a specific carrier.I proceeded to get my phone rooted and then discovered my phones knox was tripped and shows i have an custom software on it,other then bringing it to the store i haven't done anything else to my phone.
So my questions:
1.Should i do an EFS back up then Restore to official then re-root? while reading forums read somewhere sometimes restoring to official can also damage the EFS partition?
2.Should i proceed rooting my phone in the state its in or do i restore with official Firmware then proceed to root?
3.Is update 4.4.2 able to be rooted if yes,should i restore my phone straight to 4.4.2 then root?
4.if i update to 4.4.2 do i loose the ability to switch between Canadian carriers.
5.Is Knox 0X1 able to be reset for Qaulcomm yet?
6.Am i missing anything else before i begin ?

1. You don't need to restore something that's not broken.
2. Since you already tripped KNOX, yes.
3. 4.4.2 can be rooted.
4. 4.4.2 doesn't prevent you from doing anything related to carriers when compared to 4.3.
5. No
6. Flash stock using Odin by updating to 4.4.2 official Sammy NB7 ROM. Then begin there.

Follow my guide in my signature. If you update to NA2 bootloader, you are able to downgrade.
Hello
I recently got my S4 i9505. I'm planning to root it
I have Android version 4.3
I used to flash costum roms on my s2 but I'm not really planning to do much flashing on my S4. not soon anyway
So as I connected the phone to Kies to make sure the drivers were downloaded so I can proceed with rooting
Firmware update popped up
I'm not sure what the best option for me now.
Should I root now and then I'd be able to flash a costume KK rom? and are there any stable ones that are better than the stock?
Can I use kies to update my rooted phone?
Maybe I should stick with JB 4.3? Which one is better 4.3 or 4.4.2?
I remember facing some issues when I update my s2 back. So I searched for the KK Update for the s4 and some people weren't so happy with their KK update
I know that doesn't represent the majority but still it could happen to me
So I confused myself
What is your advice to me?
sorry for the long post
Also I have an extra question What is KNOX? and do I need it?

First, the most problems in 4.4.2 are fixed, so if you flash the officical, latest firmware of your country you shouldn't have any problem.
An important thing: if you flash a custom rom, your warranty will be set 0x1, that means, you lost your garanty if you flash a custom rom, that's the so called KNOX. You can use knox like a second system on your phone, with all secure data in it, you can only access with a passwort and all datas are locked without this passwort.
Root your phone after the software update if you want to root it.

thank you for your input
hello guys would be possible to downgrade to 4.3 because I downgraded to kitkat lollipop by following a guide posted here on xda and everything went well I also downgraded the bootloader now I wonder if it would be possible to the same thing with jelly beans . Thank you all . P.S. Sorry for my bad english
While you can downgrade to 4.3, depending on when Knox was introduced, you may or may not see warnings on boot regarding the kernel not being SEAndroid enforcing. Just keep in mind that once you have a Knox-aware bootloader you cannot replace it with a bootloader that isn't Knox-aware. I mention this because it's possible to go back to the very first ROM available for your device, which likely did not come with Knox.
