It depends... on what is your current firmware and what firmware you want to fallback...
It depends on your bootloader. If you're on 4.4.2, then most likely your boot loader is also 4.4. If that's the case, then no, you can't go back to 4.3.
Just out of curiosity, why would you want to? Much has been improved from 4.3 to 4.4, and we also have 5.0 now, which is an entirely new creature...

I currently have 4.2.2 with the old bootloader on i9505. I would like to keep it Knox free, but would also like
to try a newer rom. Is there a rom that is as close as possible to stock Samsung 4.3 (obviously
without Knox or new bootloader)?

Which modem would suit the PDA: XXUEML6 version? The same one that came with XXUEML6 in stock? I have heard conflicting reports about different modem versions playing not so nice and its better to match them with what came with stock rom?
I assume also that XXUEML6 WiFi_FIX will need to be flashed via Odin after flashing a modem?
clarification
So do you mean without knox and without bootloader or do you mean or do you mean without knox but with a bootlaoder as it is the older bootloader that i am trying to find for i9505. i understand some forums say you cannot roll back the firmware from 4.4.2 to 4.2. I however am having the screen rotation problem with the new 4.4.2 so i'm trying to find a way and one way might be to install a custom rom with old bootloader via CWM install zip function to replace the new 4.4.2 bootloader. This will then allow me to roll back the firmware to an older version and kill my screen rotation problems.

Sorry if this is a noob question but will running an old bootloader (say 4.4.2 NA6) with a newer official rom (like 4.4.2 NE4) allow me to downgrade using Mobile Odin Pro?
And if thats the case, are there likely to be any performance issues with running an old bootloader with a new firmware?
KitKat boatloader works on all KitKat roms. Is good to update to latest boatloader to match the rom but no biggie if not.

so then will i be able to downgrade from newer roms to older roms with mobile odin (seeing as it doesnt touch the bootloader) if i have the oldest KitKat bootloader installed?
you can move to all 4.4.2 rom you want but NO downgrade to 4.3 rom
I'm on NA6 BL with NG1 rom

Hello!
I am currently running the latest Verizon of android 4.4.4 on my Verizon note 3. As far as I am aware there is no root for 4.4.4.
Is it possible to flash back to android 4.4.2, then perform one of the older methods of rooting?
Thank you for the assistance!

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

Unfortunately, No. From what I understand, Verizon has "blacklisted" older versions so the bootloader prevents flashing anything older than 4.4.4. I believe you can flash either of the current 4.4.4 ROMS, but that is of little help.

I can confirm this; just had this happen to me and trying to flash anything other than a 4.4.4 stock ROM failed in Odin.
I've been a customer of VZW for 14 years, and I'm so fed up with this locked bootloader war with them that I'm seriously considering jumping ship. Always been happy with everything except this locked bootloader BS.
as the title says... is it working if i flash official lollipop via odin and downgrade it to official kitkat.
currently running on dead x-note development.. i want to try lolipop rom but i'm afraid what if i didnt like lolipop.. will i still able to downgrade it by just flashing via odin?

Hello,
Yes it is possible to downgrade from an official Molitor to an official kitkat (the latest).
I do it, when the flash is end and the mobile show the logo Samsung
You can put out the battery, reboot to the recovery and wipe all user data.
Before do that save all your data.
It's an official administrator from Samsung who say me do so.
Hope that can help you.

Isn't the bootloader required to flash the ROM?
I'm very afraid of trying stock lollipop. I was on Temasek's CM12 build but I had abysmal batterylife. This was probably not attributed to Temasek's build but rather to CM12 as a whole, so I went back to my nandroid containing Crash Rom V19 on kitkat 4.4.2 and I literally have less than 1% drain per hour with the phone idle. I love this batterylife, and I feel I'd like to try and see if stock lollipop TW will give me the same but I would like the option to go back to kitkat if it's worse. I like lollipop a lot but the promise of batterylife seems to hit and miss, makes me stay on kitkat.
I know Crash Rom has a lollipop version, but beside this, which ROM is the MOST stock with the least amount of modifications?
is it possible to downgrade lollipop stock rom to stock jellybean?or do i need to downgrade first to kitkat stock before downgrading to jellybean?i want to do this because i have apps that i used when im on jellybean which is not compatible with kitkat and lollipop.
Using Odin you should be able to downgrade directly to Android 4.3
You will have to do a factory reset in recovery.
I did my factory reset after downgrading the firmware, but guessing you could do it before the downgrade and then not have to worry about the auto-reboot in Odin.
Hi
I have a problem during flashing from 4.4.2 to 4.3. After start the process fails by aboot.mbn. If I remove the file aboot.mbn in the md5-package and start the process again, it works. The mobile flashs back to 4.3, but it hasn't sound and I can't record Video or Soundmemo. Please help! I don't what to do.
I'm looking forward.
Best wishes
Aboot.mbn is the bootloader. You cannot flash a 4.3 bootloader over a 4.4.2 bootloader.

Is there any way to go around the bootloader? Would it help to flash lollipop 5.0.1 and then to flash back to jelly bean 4.3 or the lollipop has a bootloader locker too.
Thank's so much!!
There is no way to downgrade the bootloader to 4.3 once the phone has been flashed with 4.4.2 or newer. This applies to many Samsung phones including the s3, note 3, note 4, etc.

I flashed my S3 from 4.4.4 to 4.3 and tab 3 from 4.4.2 to 4.2.2 without any problems...why it doesn't works on S4?
Are you sure that the ROM you used to downgrade included a bootloader?
For the s3, it may be possible to go to a 4.3 bootloader as there was no bootloader after 4.4.2 but I'm not 100% sure. I have no idea about the tab.

Hi,
yes, there were one. I've rolled my s4 back to 4.3 now, but I have no sound in it...What can I do?

You installed the 4.3 bootloader too? You may want to run Samsung Phone Info from the play store to confirm.

I'm not sure. I removed the file aboot.mbn and converted the md5 archive to tar archive and finaly flashed my s4. It works, but there's only no sound in thy system.

I'm not able to downgrade it from lollipop too. I haven't the option to unlock the oem in the developer options
The OEM unlock bootloader option is only useful where a phone has a locked bootloader. In the case of your s4, the bootloader is not locked and cannot be downgraded.
The aboot.mbn file is the bootloader and removing it means the phone is running a 4.3 ROM on a 4.4.2 bootloader. This is probably why not every works properly.

How can I solve this problem?
You can solve the sound problem by flashing a newer ROM.
You cannot downgrade the bootloader and trying to downgrade may brick the phone by damaging the bootloader.

Why it worked with tab 3 and s3? I saw many videos on youtube, there rolled guys the system back...Well, Ithink it's my fate to have the kitkat. I hate this system.
The s3 and Tab 3 are totally different items. Being able to downgrade a bootloader on one device does not automatically mean every bootloader in a company's product line can be downgraded.
Have you tried running a custom ROM on the phone? You may find those more palatable.

Can I flash for example cyangenmod 12 and then flash android 4.3?
There is no way to run a completely stock 4.3 ROM, including the bootloader, on the s4 once it has been upgraded to 4.4.2 or 5.01.
