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,
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!
Which Android version is better for our i9506 : Jelly Bean 4.3 or KitKat 4.4.2

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?

Hello people, I have been lurking and I was here last year to root my SCH-I545 and I still have the android version 4.2.2 . I know it was impossible to unlock the next version (4.4.2?) so I just moved on and kept using 4.2.2. So where is the official unlock for the latest version for SCH-I545? Is it supposed to be the same as i9500 or i9505 or i9505g? And I want a root of the official verizon version, not cyanogen or watever release group there may be. (no offence). I've tried your stuff but its just buggy sometimes and it feels weird. Sorry I didn't mean to diss the whole community of developers out there, I'm sure people appreciate your hard work and dedication.
But back to the main point, I want to update my rooted Verizon SCH-I545 from 4.2.2 to the latest version, please show me where to go.

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.
