is that possible to downgrade from 4.3 to 4.2.2 on my i9505?
I did read some subjects about that the 4.2.2 is better than 4.3 , and the downgrade is impossible because the knox will refuse the downgrade process , so if I root my i9505 and flash any 4.2.2 custom ROM with knox free , after that , is that possible to flash the stock 4.2.2?
thank you my teachers

the only way that I know of to downgrade to 4.2.2 is by flashing the south african 4.2.2 firmware and then you can flash your country's 4.2.2 firmware

[Q][I9500]What Happens if we flash Indian 4.3 ROM on a device with Russian 4.3 ROM

What will happen if i flash a device which has Russia's(or Other Countries) 4.3 ROM , with India's 4.3 ROM? Will it set the KNOX warranty Bit flag.
I bought my phone in India. After i started using Omega ROM which has MG9 modem, i was never able to switch back to Indian Stock 4.2.2 which had MG5 modem, as in MG5 modem i was getting a generic IMEI and the network was not working. So i settled for using the KSA 4.2.2 ROM which has MG9 modem, hoping someday India ROM will get MG9 or higher. My device still shows the Official Status in the Download Mode.
My big problem now i how do i get back to Indian Firmware without voiding the Know warranty. Can i wait for 4.3 to release in KSA and then flash back India's 4.3 so that i dont face the IMEI problem with the ROM's? If i do this will it void the Knox warranty?
Or flash the MG5 ROM of India and get the official 4.3 India update? will this solve my IMEI issue?
I also heard that there is a binary counter for the number of times a Custom ROM is flashed. If we upgrade to 4.3 with non-zero binary counter will the KNOX warranty void flag?

Incase u hvnt installed 4.3 yet -
Oky, heres what u do: revert back to stock 4.2.2 android, then go to software update, (it will b good if u use triange away and remove the no.) and u shud receive update for indian firmware, since bootloader is installed later u wont loose ur warranty(when u will install it for first time the warranty bit says 0 ..)
I installed 4.3 russian fw by mistake and since my warranty bit was 0 samsung installed indian firmware on my phone(had to fight a lil tho ..)
Dnt do anything after flashing 4.3 for first time, since whatever u do will trip a flag, thus voiding the warranty ... i had isssues getting my phone fixed even at warranty bit 0 ..
Hope that helped ...

Hi,
You said that you used OMEGA rom. It means you rooted your phone and installed CWM recovery. Now you installed I9500XWUBMG5 4.2.2 stock rom and updated to stock 4.3 via KIES or OTA. My question is now your KNOX warranty is 0x0 or 0x1.
Could you please confirm I want root my phone.
Thanks.
What will happen if i install russian 5.1.1 to my indian galaxy note 3 neo
hello guys any one here i had flash indian firmware were few days ago bt now i want to back to nepal firmware ...my device is j7 2016 model plz help me to go back to nepal firmware again
@rohit gurung: The forums for your device are here. To install the Nepal firmware you need to download it from a site like Sammobile and flash it to the device just like you flashed the Indian firmware.

Reverting to stock ROM

So my friend asked me revert his S4 GT-I9505 to stock 4.4.2 because he cant upgrade because of root.
He didnt tell me from where he got phone.
I found this
AP:I9505XXUEMJ7
CP: I9505XXUEMJ7
CSC:I9505MOTEMJ8
I cant find any firmware on SamMobile for that
If i cant find correct firmware to revert via Odin can i use some carrier version?
Thanks
- All firmwares are HERE.
- Direct url for android 4.4.2: HERE
*EDIT: Dont try to flash again android 4.2.2 coz ur friend had MJ7 (android 4.3). You can't downgrade. Flash android 4.3 again or android 4.4.2 simply. Good luck.
Thanks man!

[Q] 4.4.2 bootloader which stock 4.4.2 firmwares can i downgrade to?

Sorry for the newbie question i am using samsung s4 from o2 uk and have their 4.4.2 version, i am unlocked now so can downgrade or upgrade to BTU unbranded 4.4.2 versions of which there appears to be 4 available in sammobile.
I understand that there is a new bootloader in 4.4.2 so am i able to upgrade /downgrade to any of the stock 4.4.2 firmwares without tripping knox or losing my imei?
I know to my annoyance that the new bootloader efs v2 in 4.1.2 xxemg4 for the samsung s3 prevented me to downgrade to any of the previous 4.1.2 stock roms due to this much to my annoyance as the battery life was superb on xxemc2 4.1.2 so i don't want to make the same mistake with 4.4.2, does anyonr know if there is another bootloader version in the latest 4.4.2 stock rom that may cause a similar issue?
Bear in mind i only want to be able to up down grade to any of the 4.4.2 that is available not go to 4.3 or up to 5.0 as far as you're aware are all versions of 4.4.2 BTU ok to flash in odin without issues?
no downgrade from kitkat

I dont think you follow what I mean I dont want to downgrade from 4.4.2 per se I just want to use the other stock versions of 4.4.2 kitkat that have been released. Am I unable to downgrade from a higher version of kitkat to a lower previous version of kitkat that was avaialble a month before?
Same BTU stock version ie ugn9 down to ufn8 or something

Yes as long as you are downloading the correct firmware for your phone based on model number you will be able to downgrade. Just use Odin and you should be set.
You can flash any 4.4.2. The different versions don't matter.
Are you 100% sure i can up or downgrade to any of the 4.4.2 versions?
I dont want to make a mistake like i did with my s3 whereby i updated to 4.1.2 xxemg4 the latest version of 4.1.2 available but had an efs v2 so was unable to downgrade to any of the 4.1.2 versions below it.
4.4.2 kikat has a new bootloader but they all have the same efs version right? Thanks for the help

Downgrading from stock 5.01 to stock 4.2.2 could have tripped knox and set the screen to say custom.

KK = Kit Kat which is 4.4.2. My mistake because 4.2.2 is Jelly Bean.
I searched sammobile.com for the s4 gt-i9505 and only found firmware for the link in my post above. Following your link, I found the firmware.
As far as I know, Knox did not exist until the 4.3 firmware which leads me to believe that the bootloader on the phone is either 4.3, 4.4, or 5.01 while the modem is older than 4.3. This may be causing the problem. As a test. flash back to stock 5.01 to see if sound and wifi work.

I flashed back to 5.0.1 and Sound & WiFi now works again - what does that mean ?
How do I then Flash back to a Stock 4.2.2 ROM and have Sound & WiFi work after that ?
If it works on 5.01, then at least you know everything is working properly and the problem is the 4.2.2 rom.
i don't believe you can downgrade the bootloader to stock 4.2.2 which means you cannot run a stock 4.2.2 rom on the phone because the phone will have a bootloader that is not compatible with 4.2.2.

WT ??? Does that mean if you upgrade to Stock 5.0.1 you can NEVER downgrade back to Stock 4.2.2 ??
Yes, it certainly looks that way. On my i337m, I can flash back to stock 4.4.2 but nothing older.

Google you s^#(k !! how dodgy is that not allowing people to downgrade if there upgrades are crap!!
Is there another way ??
Can I downgrade back to 4.2.2 with another Bootloader or custom ROM ??
Would surprised if I am the only one in the world that wanted to downgrade and there was no known workaround ...
It has nothing to do with Google as it is Samsung that locks the bootloader.
If a phone could fully downgrade to a stock 4.2.2 rom, including the bootloader, I would not expect to see any references to Knox in download mode.
You could search but I have not seen any posts where an end user was able to downgrade the bootloader to a non-Knox version.

When you downgraded from 5.0.1 to 4.4.2 did you get any Know Issues OR Loss of Sound OR Loss of WiFi ?
Does the downgrade need to be a stock ROM ?
Knox was tripped from 0x0 to 0x1 but everything worked, probably because the everything went to 4.4.2, including the bootloader.
The downgrade does not have to be a stock ROM. Running a 4.3 or 4.4.2 custom ROM such as CM does not alter the bootloader or modem.

Does that mean I can downgrade from Stock 5.0.1 all the way down to Stock 4.3 with no issues except Knox tripped to 0x1 ?
Or does it have to be a customer ROM to have no issues ?
I have never used custom ROM's only Stock ROM's
Some bootloaders can be downgraded to 4.1.1 like I did with my note 2 but the s3 can't be downgraded at all. I think the s4 is limited to 4.4.2 .
Downgrade i9505 to 4.4.2
I downgraded my galaxy s4 i9505 from 5.0.1 to 4.4.2 and knox flag was not tripped.I think it will be tripped only if you flash bootloader without knox.Maybe if you don't care of knox flag and want to run android 4.2.2 you must flash kitkat modem to have working wifi..
Hello mr. Marduj5
I'm also a Galaxy S4 user and want to install stock 4.2.2. I did everything you said... but the only problem now is the microphone and the speakers don't work after flashing Kitkat modem. I had the Connections but the media is now the problem. Thanks for the help...
