[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?

[Q] New 4.4 bootloader questions!

Well, i was so stupid to flash the new stock 4.4 TW rom just to try it but after reading some topics it seems i am stuck on tw for now and can not go back to cm11.
How far are the developers on getting an AOSP running on the new bootloader? Or has anyone managed to go back to the 4.3 bootloader?
or is it possible to use the stock 4.4.2 kernel on cm11 and solve this problem that way for now?

I have the n9005 so if the crack the problem that should be one of the first devices
I hope that is comes soon, but for now its TW for me.
Just installed the google launcher so it eases the pain a little.

[Q] KitKat Bootloaders?

Been looking around for a bit for this and figured maybe someone could give a yes or no...
Is the KitKat bootloader issue (can't go back to 4.3) a Samsung thing or is it in the Google versions? i.e. if I try an AOSP 4.4.2 ROM does it write an incompatible-with-4.3 bootloader onto my N3?

Bootloader is a Sammy thing ,you can download aosp but has to be jb one if you are on jb , so you need the hiltxx one but they don't get updated any more

Thanks Jay. I have yet to see a decent reason for going to KK so I guess I'll wait... I'm on Alliance ROM (4.3) and Philz Recovery with lean Kernel - phone is very quick, gets around 3 days battery (I'm not a heavy user, but at worst I get almost 2 days from it) and have Wannam exposed running so I can config it how I like it.
If it ain't broke, I don't fix it. (or not until something wonderful comes along using KK... Or if Alliance goes KK... )

That's not true. AOSP KK ROMs work fine on a JB bootloader.

If you have the developer edition of the Verizon S5 bought directly from Samsung, then yes you can flash this and CM12. Since you mentioned safestrap I'm going to assume you have the retail version of the Verizon S5, so no you cannot flash this, CM12, or any AOSP based ROM.

hmmmm

To be honest i am not quite sure of it origins we got it in china and the software that came on it before i flashed the Syndicate rom just said g900 so i take it it had some custom Chinese firmware. (see attached) i have made a backup so i can easily flash to its "original" state
Alsi i am in the UK and running three mobile
Edit: also if i can not flash CM12 how can i get a lollipop rom with Nexus style i hate touchwiz i had been using S4 rom with nexus style lollipop and i like it so much better

I don't think this is possible yet. Our only hope for something other than TW is probably the Eclipse ROM but that's AOSP style.

Thanks
