Hi guys, has anyone tried installing a 4.3 ROM (not ODIN firmware) on a N9005 (not exynos)? And if yes, how did it work out? Thanks.

It works fine as bootloaders are compatible with the "bootloader generation" and backwards but not forward. For example: You're rocking 4.4 bootloader but want to go back to 4.3....which is fine. In another scenario: you're rocking the 4.4 bootloader but want to upgrade to 5.0, this will not work because for each update brings a new bootloader. So backwards compatible but not forwards, comprende?

First of all Hi everyone!
I bought an S4 for my girlfriend and have a question regarding this Knox bullsh*t. When I bought it out was running 4.2.2 i9505xxubmga firmware. I rooted and installed aosp rom on it. But she doesn't like aosp apparently..
So i wanted to know if it is possible to flash 4.4.2 Samsung rom without upgrading the bootloader to Knox enabled one?

Hey,
sorry, this is not possible with stock Samsung rom. When you upgrade to 4.4.2 knox bootloader will be activated. But it is possible to go back to 4.2.2 mga, this firmware uses the old knoxfree bootloader.
Edit: i think you can install a Samsung based custom rom like imperium rom, this is also knox free and compatible to the old bootloader but I'm quite not sure whether this will enable knox. I think it won't...

You can flash any custom rom you want. 4.4.2, 4.2.2, 4.3 etc. It doesn't matter.
You need the correct modem though if you have the old bootloader and anything above 4.3+ rom. You have to do some searching on the correct modem I can't remember which one it was.
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

Hey guys,
My brother has the S4 i337 model and he's on 4.4.2
This phone is unlocked and he's using Tmobile on it.
For some reason it cannot find 4.4.4 via OTA and Kies
Is this because it's on tmobile or this model didn't get 4.4.4 yet.
Do I need to root it and flash a rom on it?
Thanks

Some models of the Samsung Galaxy S4 just didn't get the update, for instance my i337 didn't even get the 4.4.2 Kitkat update and was stuck on JellyBean. Your best bet is to just flash a 4.4.4 Rom on it. Clears out the bloated stock software.

that's really lame
So to make sure I do this the right way
I have to root the phone first
then install custom recovery
then flash rom right?
Or does the boot loader need to be unlocked?
Any rom recommendations?
I'd like for it to be stock so it's stable since my brother needs this for testing purposes

Yes correct, but if your boot loader is locked then you're going to need to download SafeStrap Recovery for locked bootloaders. Then once you have installed that, there's only very limited amount of Roms you can install because of the kernel, if you find a ROM that changes the kernel your phone won't boot. But a ROM that is fully working is called "GoldenEye ROM" its a 4.4.2 ROM but is really clean, stock, and clears out all that bloated nonsense. There's no 4.4.4 Roms for locked bootloaders yet.

thanks for this info
I'll look into it
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?
I'm looking forward.
Best wishes.
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.

In 2013 there were S4 with 4.2.2. Why I can't roll my system back?
I'm on Phoenix rom on 6.0. 1 and I'm sick of the weird path name it gives the external SD card. It messes with link2sd and my Manga Reader. I was wondering if I can simply flash a kit Kat rom on miui without ruining anything...
no
So I'll have to go back to stock first via Odin?

you cant do that either. Once you progress past 5.0, youre stuck
I directly downgraded to 4.4 with my G900W8. However, you need to be careful with which version you are going to flash. For example, when I flashed any other 4.4 firmware than NCG (Which is the first version of 4.4 released for G900W8), I faced bootloop.

there is a physical fuse that gets tripped in the S5 once you go past 5.0 that is there to no allow you to go back. Not sure if you were on a 4.4 bootloader that allowed you to do this or what, but trying to flash back to 4.4 after being on a 5.0 baseband is very ill advised
I don't think you can down grade to kit kat, but you can go from marshmallow to lollipop. I just did it last weekend. Check this...https://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370
I hope it helps you.
Actually i can downgrade anytime from MM to LP or LP to KK
but i didnt tried MM to KK yet.... tried it many times it works.. unlocked G900F
Edit: im talking about stock rom btw (from sammobile)

then you dont have a MM bootloader. I just re-read some posts that confirm that the phone locks to 5.0 once you get that bootloader. Its not possible to go back, and it doesnt matter if you have the G900F or not

Then if there is a physical fuse, why was I able to downgrade from MM to KK? One difference when I downgraded from MM to KK NCG was that "Powered by Android" logo was changed to old style. I think NCG build of KitKat changed bootloader from MM one to KK one. Baseband wise, I also flashed KK baseband and it worked very well. It might be different on G900F but with my G900W8 I could go back to KK.

not sure, but ive had my G900P for 2 years 10 months and have been constantly on XDA since my OG evo back in the day (the one with the kickstand) and everything ive ever read saya that once you go past 5.0, you cant go back. Not sure what you have going on there, but there are tons of posts going back several years stating exactly this
Of course you can downgrade to kk.
Just download the kk firmwafe. Pull out battery for 5 sec. Then flash trough odin. Did it mant times and no problem with that.
i did that on my galaxy s5 and it works
