You can't :highfive:

Why can't he? Can't he just download a 4.3 ROM and flash it via Odin? I think he can! Warranty will be voided as counter will go up, but that's not the point.

When i flash with odin it shows fail

What if he were to have a nandroid backup? Would that be sufficient? I'm curious to know because I'm still on 4.2.2.

You simply can't. new bootloader comes with 4.4.2.

[Q] Cannot downgrade from 4.3 to 4.2.2 - Galaxy S4 i9500

After upgraded my S4 i9500 from 4.2.2 to 4.3 XUEMJ5 via Kies, I'm having a lot of troubles regarding battery drain and overheating.
I came to the Samsung Services Center yesterday and asked them to downgrade my device back to 4.2.2, but their answer is "Sorry, we cannot do it. Once upgraded to 4.3, there is no way to reverse to 4.2" ?!?!!?!?!
Is it true? Has anybody tried to downgrade your S4 from 4.3 to 4.2
Thanks for your advice!

I had the same issue. There seems to be a problem downgrading to certain 4.2.2 roms. I eventualy managed to downgrade using the South African version (I9500XXUBMH1) . After you've flashed this,you can re-flash whichever ROM you prefer.
Give it a go and let me know.
Cheers
you are you kidding

Are you really serious? So you can downgrade from 4.3 to 4.2.2 using that firmware? What does your knox say in download mode?

Unfortunately it states:
Current Binary: Custom
System Status: Custom
Warrant Bit: 1
But it doesn't really bother me for now, until I have to send it back for repairs I guess
I'm sure the Chainfire guys will eventually be able to reset this counter as the TriangleAway is currently not supporting the GS4 I9500.
Cheers
So is there a specific way you have to flash it or do i just use odin?
Do i flash the roms back to back or what?

s4 i337 to 4.3

hi,
I want information,
if I install the upgrade to Android 4.3 on my s4 SGH-I337,
I lose root and recovery?
thanks
Are you upgrading using official Samsung ROM or custom 4.3 ROM?

If you upgrade to the Official Samsung OTA from 4.2.2 to 4.3 there is a possibility that you will lose your root and 100% you'll lose your custom recovery. Due to the locked bootloader, you won't be able to flash a custom recovery onto your phone.
If you were on MDL and you did the update, you are now locked down...
Should read a little more, before jumping on updates.
Good luck.

Did you do a factory reset BEFORE doing the ODIN flash downgrade to 4.2.2 ?
If not you need to do that and reflash using ODIN.
Also be 100% sure that you are flashing the correct and specific model/baseband
version of the 4.2.2 stock firmware for your phone.
Only use/download ODIN flash stock official firmware from: http://sammobile.com
for best results.
Good luck!

I would factory reset my phone but I would still get a error, does the process only work with the international version of the S4? because as far as t-mobile, I don't think we have any luck in downgrading to 4.2.2

all you need is reflash official 4.3 firmware using odin. once updated to 4.3 it is impossible to downgrade to official 4.2.2.
so just reflash 4.3 official again and your device will boot up. i myself faced this problem .

so it's impossible to downgrade to official 4.2.2, but is it possible to flash a custom stock rom on 4.3 or 4.2.2 (like a modified stock rom)?

You've most likely got the KNOX bootloader due to this you can not downgrade to an earlier version of an official rom. Custom rom's should work fine not sure about 4.2.2 roms.

Would a equalivalent version of a custom rom work? because I plan to install jovy23's stock SGH-M919 4.3 modified rom, but I am not able to install it due to the errors given by CWM and TWRP

You can flash stock rom 4.2.2 through odin to downgrade. You can find the rom in the forum of I9500 or on sammobile.com. But you may face problems with IMEI. Happened to me.

[Q] ODIN flashing older rom.

Hey guys so i have heard that if i install the old firmware for my s4 from sammobile using Odin one from early 2013 that it will give me access to service menu so that i can unlock my phone. So my question is that is it 100% safe to Odin flash the older 4.2.2 rom when i am on 4.3? Can i flash it unlock my phone then upgrade my phone to a custom rom again? Thank you

Do not do this. This will brick your phone. If I am not mistaken, there is a method to unlock mk2 in the general section.

You should ask this in the t mobile s4 forum. I believe your bootloader is unlocked and you can flash an older firmware version. But check there first. This is the att s4 forum. It can't be done on the at&t s4.
Is the service menu missing on the stock T-mo 4.3 ?
Nooo guys i have an unlocked bootloader i have the s4 that is very similar to the tmobile and it's the same as the Canadian versions. And yes the Canadian version which is 1337m and mine which is m919v don't have access to service menus but i have flashed a lot of custom roms simply by philz recovery so doesn't that mean i have an unlocked bootloader?

If you're on 4.3 I believe you also have Knox, in which case I don't think you'll be able to go back to 4.2.2. Read through this http://forum.xda-developers.com/showthread.php?p=40903040

Did you ever take the ota to 4.3? Do you know what firmware your device is on? A 4.3 custom Rom wouldn't have knox but if you took the official update to 4.3 you would have Knox.

Hmm i think then yes i might have knox. I think at one point i might have been on stock 4.3 is there any way that i can check to see if i have knox? And if i have knox i cant flash an older stock firmware for my s4?

Idk, I'm not that familiar with your device. From the little bit of reading I've done I would say no, you can't flash an older firmware. But again, I'd post this question in the t mobile forum. They'd be more familiar with your device.

Did you ever update you device with kies or ever take an over the air update ? It's fine if you were on a stock based 4.3 rom as long as you never took an official update. If so then you can't go back. Just flashing a stock 4.3 rom won't change that status but the 4.3 bootloader would.
You would have know by checking in settings under SE
