[Q] Downgrade to older stock ROM N9005?

[kylothow]

Hey all!
Is it possible to downgrade from a newer (NE3) firmware to an older (ND3) through Odin or it will brick my phone because of the bootloader?
The only things I know are that 1) Downgrade from 4.4.2 to 4.3 is not possible 2) It's possibile to install a custom older rom on new bootloader and vice versa BUT I don't know if it's possible with stock roms with Odin.
I looked for a solution but nothing found and no one answered me so I opened this thread to find out a solution.
Thanks in advance.

I never actually tried going back to an older version but I really don't see why you shouldn't. As long as it's KitKat 4.4.2 just try it should work. I downgraded my Modem and haven't had any issue.
With the Bootloader worry...did you even change the bootloader? As well as the Modem you have to do that separate to the Rom, as flashing a Rom doesn't touch Modem an Bootloader!!! If you don't know how to do that please just leave it alone though unless you read, read, read a lot on how to do that.

Thanks for the reply, every time I install a new rom I make sure to update the bootloader and modem too, and from what I can read from the Synapse app I have the NE3 modem and NE4 bootloader.
I'm asking how to go back to older roms because going from 4.4.2 to 4.3 updating the bootloader with Odin you obtain only a fancy paper weight, and I didn't know if going from newer to older 4.4.2 bootloader it was the same story.

I'm pretty sure there won't be an issue mate since I flash between custom roms almost daily which are most of the time different models. If you want to be 100% sure wait for someone to confirm as I'm rooted since I got the chance to do so.

Thanks to the developer Civato I read on his FlexKat thread he correctly downgraded his bootloader from NE6 to ND6 with Odin...
So problem solved, this is definitely possible.
Thank you everyone for your replies :good:

Downgrading bootloaders on the same version generally tends to work OK, mainly because on 4.3 Samsung patched the security flaw which stopped you going <MJ7

Kith Kitkat I never had any issues flipping back and forth.--- Until it's a BL upgrade with OS Number change (IE: 4.4.3 if it has new BL) then it shouldn't work.

hi. sorry,this is probably an old thread but I need some help,please and somehow,Google got me here. I want to downgrade (not really downgrade) my N9005 to 4.4.2.
I currently have a custom ROM(resurrection remix v5.6.9,in settings it says that I have android 6.0.1 marshmallow). Also,I have a custom recovery(TWRP). Well,I would like to install the KitKat stock ROM and really did a lot of research but I cannot find it anywhere :'( . Do you know any source? And also,can I flash it with mobile ODIN? When I opened Mobile Odin Pro it said that if I don't have the boot loader for the ROM I want to install then I will experience a soft brick. Isn't TWRP a good boot loader?
Also,does it matter what version of N9005 I own? mine is: XXUGBOJ1. Could I flash smth that is not for this ..base band is it called?...
pls help
I'm such a newbie and I don't wanna mess up

Get a 4.4.2 fw and flash with windows odin. Not really familiar with mobile odin. Find fw for you country csc. Flashing other csc fw sometimes requires pit file so better get the 1 for your country or originally came with the phone.

Samsung updates.com.
I can see a few for Romania with CNX, ORO, COA, ROM, HAT csc.
But they very old. Probably not downloadable.
