I flashed the stock UK NF4 rom and then tried flashing the Australian NE3 rom over it but it won't go past the Samsung logo after flashing it.
Nope

My understanding was that you could flash and kk over each other but not downgrade to jellybean.

NF can't be downgraded to NE. AFAIK.
Once the letter upgraded u can't gi back to previous letter series. It will be considered downgraded.
The bootloader is different, and it is the ome which lock the downgrading process.

When did Samsung start doing this? When I had my s3 I was able to downgrade to any version but now I can't even downgrade at all. This is really frustrating. Now I'm stuck on a firmware that cripples my GPS.

With the introduction of JB.
You shouls really research these things beforehand. Mainly because it's mentioned i n pretty much every flash thread.

samsung started this stuff when they started to use KNOX.
They agressively update the bootloader for any patches useful to protect their system evironment. Therefore, in KK, AFAIK, any changes of the firmware letter, means new bootloader.
what most of users do normally (if they have a rooted device), is just flash a newer custom ROM, and stay with their old bootloader (KK). By doing this way, you still can jump any older custom ROM base without any problem.
But once you flash a new original firmware, it will flash the new bootloader as well. And it is non-downgradable.
cheers.

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?

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.

Samsung build some protection so you can't downgrade, for how long that's another story. Anything software can be broken, it's just the matter of effort, keep your eyes open, maybe somebody will find way.

I just read an interesting news. Apparently, some canadian phones ( SM-N900W8 ) when flashed with the newly released Mexican 4.4.2 can downgrade back to a 4.3 firmware. Did somebody who flashed the Poland 4.4.2 tried flashing it and maybe you guys can downgrade to 4.3 after as well? It's just an idea I haven't really tried it.

I also have an S3 i9305 with tripped knox bootloader after upgrading to 4.3. I have not tried to flash stock 4.1.2 on it after that, but it is not a problem to flash a custom 4.1.2 or 4.2.2 custom ROM on it.
Is it only samsung signed ROMs that won't boot if it's downgraded? And custom ROMs is not a problem as long as you don't try to downgrade the bootloader?

Samsung did changes on the bootloader since MJ7, once updates cannot downgrade.
Also new firmware OS need new bootloader, means once up to latest KitKat that need new bootloader, they is no way to revert to older version as of now.

Well for us SM-N900W8 users it's possible to flash back to 4.3. Just took Mexican 4.4.2 for a spin and to me looks the same as 4.3 so I'm back to 4.3 as there's not that many 4.4.2 custom roms out yet.

Also I am wondering about downgrading for 4.4 (when it comes) to 4.3. Is there a surefire way to upgrade and downgrade between 4.4 TW 4.4 CM and 4.3TW? I would not mind voiding my Knox counter.

I played around a bit earlier... The only firmware you can upgrade to 4.4.2 and downgrade back to 4.3 is the mexican telco one for the n900w8, however I had some issues but will play some more tomorrow when I get time. As for KNOX, it's just one of them things we have to live with I'm afraid..
EDIT: I'm gonna mess with the bootloader and see, doubt it can be matched/mixed to work with the N9005 but what's the harm in trying.

Sorry. Can't understand exactly. What exactly means what versions you can run with a new bootloader?
MJ7 is the bootloader that powers CM currently. You need a bootloader to be able to boot into the operating system. Like a key into the phone.
If you upgrade your bootloader to a newer version aka NA6 it locks the phone. Therefore anything that runs lower than NA6 aka MJ7 won't work.
Think of it like, you broke your door, you got a new door and tried to use the old key. It no long works.

hi, can you elaborate?
i always thought samsung doesn't let you downgrade to an older bootloader. but if you install CM (not samsung official updates) the bootloader doesn't get updated so you can downgrade in the future.
unless you upgrade to 4.4.2 official samsung ROM and update the bootloader, then you'll never be able to downgrade again?

I was just wondering if one can update bootloader only or does he have to update the whole firmware. Lets say I'm on 4.3 JB and would like bootloader 4.4,can i just simply flash bootloader only?
Do i have to use Odin or can i use cmd flash procedure as for nexus?
I'm asking because lollipop needs a updated 4.4 bootloader as far as i know..
Any help would be appreciated.

Yes, if you manage to get a bootloader only file.
But do keep in mind, that currently 4.4 bootloader works only with 4.4 ROMs (and those custom CM12 ROMs that are made to work with it). You will not be able to revert to 4.3.
Thank you for response.

It sounds to me like the aboot qfuse counter changed which would mean that there's no going back to any previous FW. It was only a matter of time before they did it since the VZW S4 lollipop update did that.
We won't know until we get ahold of either the update.zip or the odin tar. I have 2 VZW S5's and both refuse to tell me there's an update available even when I Odin back to a stock FW.

It's most likely more of a Verizon thing than a Samsung thing. Although with the 5.1.1 S5 update on T-Mobile, the kernel prevents rooting and T-Mobile phones are on unlocked bootloaders which means they don't care if you root or install a custom rom so maybe it is becoming more of a Samsung thing now.

the thing is, with Verizon, you can choose to not accept the upgrade a few times, but ultimately, it is forced on you...which is why I rooted my S5 the same week I bought it (to avoid unwanted 'upgrades')
