Hi,
For my employer, I developed an app which needs Android 4.1.2 to be executed. Some employees will be equiped with S4 GT-i9500. I would like to downgrade those phones to Android 4.1.2.
I need to know if S4 GT-i9500 is compatible with Android 4.1.2 and if the downgrade from 4.3 is safe.
Thanks in advance you for your help.
Nadir,
i think the best you will be able to do on stock samsung rom will be android 4.2.2.
and i am not sure any custom rom developers will invest time in developing android 4.1.2 rom for the s4.
It can almost certainly be said that you can never expect to find a 4.1.2 ROM for GS4 as it had 4.2.2 as it's initial ROM. So the more viable option would be to make your app compatible with 4.4 (to make it futureproof!), or at least 4.2.2!

im using currently my S4 9505 running on JB 4.2.2. Do we have any stock JB 4.1.2 or Cyanogen 4.1.2 that works on S4? Im planning to go downgrade instead than going to JB 4.3. Because My software Navitel 5 dont work on JB 4.2.2. that why im thinking a downgrade.
any advise from anyone>
thank you.
the galaxy s4 ships with 4.2.2.

there's never been a ROM with a lower version number than 4.2.2 from what I know. I don't think you'll be able to do what you want to do on the S4.
there's no ROM for you to flash, because around here everyone likes living on the bleeding edge, people spend months working out how to upgrade software, never to downgrade. sorry.
ohh i see.. Thanks for the reply and for some info
Hi
I've installed the new official 4.3 rom with knox on my galaxy i9505. Now after KitKat announced I want install this (when they release a rom, AOSP, that fits to i9505 (not the google edition).
I've already rooted my device so it flagged as 0x1.
Is there any way that I'll be able to install the AOSP kitkat 4.4 on my device? (I don't care from the warranty)
I really love the touchwiz 4.3 but the kitkat looks amazing, and it's AOSP - so should work much smoother than touchwiz..

My baseband version is: I9505XXUEMJ5

i didn't see yet, but it should release soon..... doesn't it? and I just wanted to ask you that question in order to make that clear...
By the way, a hypothetical question: can i install android 4.3 AOSP right now on my i9505 after the 4.3-knox-enabled update?

AOSP is custom - Yes
but to talk about KitKat is very very early, with the Knox headaches are not clear let alone to talk about something that is not there

And when do you think KitKat will release to i9505? (just a question.. if it doesn't allowed here to ask I'm sorry)
I've seen that the knox is a bootloader. There is no way to burn another bootloader to device? and in general, android should be open source - samsung doesn't pass the law?
and last question, if I'll install 4.3 AOSP to my i9505, can I do OTA upgrade to 4.4 AOSP and make my device to look like i9505G? I've heard that there is no difference in hardware between the two devices.

Look like Google Edition yes, but turn it into one, and to receive OTA is impossible

Ok thanks a lot
What I understood is that if you update to 4.3 manually you won't be able to update with Samsung released 4.4 later OTA. But will we be able to update to 4.4 manually ?
Which Android version is better for our i9506 : Jelly Bean 4.3 or KitKat 4.4.2
RubenMMS2
Kitkat
KitKat is better, even 4.2.2 was better than 4.3 slowmo..
The SD card restrictions in KitKat create too many limitations for my liking. Even with root and SDFix, some apps still can't access the external SD card. On top of this, there doesn't appear to be any significant improvement in performance or battery life.
Maybe when someone does a good sammy custom rom based on 4.4.2NNE (would I love an Omega rom right now!) it will be a worthwhile update. In the meantime, if you have 4.3, stick to it. As I discovered to my annoyance, there's no going backwards.
Any team will cook for i9506??It's a shame
In my opinion they are almost the same Sh*******t with few changes.
I'm just using the i9506 since 4.4.2.
I'm rooted, debloated and adfree.
For me the system is fast, stable and handy.
I like it and don't miss something.
PS: SDFIX: If you fixed the ext sd write permission than any app should work...
Are you sure you've done it correctly and being rooted?

I am quite pleased with 4.4.2, my only problem is that at the moment you cannot root without activating KNOX.
For this reason I wanted to downgrade to 4.3 where you can root w/o voiding the warranty.
Anyhow, your post surprised me, because you say that even 4.2.2 was better than 4.3
Do you mind to tell me (us) why you think so?
What is wrong with 4.3?
Should I really stay far from this 4.3?
Many thanks in advance.

I moved since a couple of months to v4.2.2.
So far so good.

Hey folks. I have a question. I want to back down to Android 4.4.2 on my Note III - N900V. The performance both in battery life and signal performance absolutely SUCKS.
I'm currently on Stock (rooted) 4.4.2.
I've downloaded Stock Rooted JellyBean 4.3 N900VVRUBMJ7 http://forum.xda-developers.com/showthread.php?t=2518704
However I want to back down on the radio firmware as well. I'm pretty sure for compatibility purposes I need to. I'm having a heck of a time finding it out there. Does anyone know where I can find a pre 4.4.2 radio driver/firmware version?

Sorry for my language
Yes. Stop trying to downgrade to Android 4.2.2. Especially if you've upgraded to stock 5.0.1 at any point in the past.

Yes i know that , but i haven't find any xperia rom for i9505 based on TW unless this one on TW 4.2 JELLYbean
I can't help you there. But if you want an up-to-date Xperia ROM you're going to have to build it. You clearly cannot use the one you found.
