[Q] Old Bootloader

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

[N910F] Downgrade from POF2 to ANK5?

Is it possible to downgrade the N910F from Lollipop (POF2) to KitKat (ANK5)?
YES, IT IS POSSIBLE.
Before yesterday I've never used KitKat on my Note4.. When I bought the phone I had no time to try it (KitKat) because I've straight rooted it and flashed a Lollipop based ROM.
Then yesterday I wanted to try a KitKat based ROM and I've lost about 30/40min looking in the forum for the answer to the question Is it possible to downgrade the N910F from Lollipop (POF2 or whatever) to KitKat (ANK5)?
I could not find a proper answer.. there was this BOF5 bootloader can not be downgraded but it was always in a "strange contest" and it did not convinced me.. after 30/40min I said ***k *t and I just performed a full wipe from TWRP, flashed ANK5 modem and bootloader via ODIN, and installed the KitKat ROM from TWRP.
Sorry for the Question/Answer but this thread may will help someone to save time.
P.S.: My KitKat adventure lasted only 10min... It looked ugly to my eyes! Went back on POF2 and now trying out AICP

When you flashed that lollipop-based rom, that was a custom rom I assume? Did it contain a bootloader? Maybe you were still on the KitKat bootloader.

Yes, it was a custom ROM. No, it didn't contain bootloader. No, I wasn't on the KitKat bootloader, for sure my bootloader was POF2. Trust me if I tell you that before the KitKat ROM I've flashed too many Lollipop ROMs with many Lollipop bootloaders.

Updating to a newer ROM version.

Hello guys, I've been wondering that is it safe updating my Note 4 which is currently flashed with SimplRom 5.0.1 to the newer SimplRom 5.1.1 version without wiping out my phone? I've already google about this topic but it came out multiple answers so I thought I'll a clearly answer here.
Thanks

Yeah you can do. Just flash the 5.1.1 bootloader and modem beforehand. If you have the N910F then the latest bootloader and modem is POK1

Either way you're going to lose root.
Don't hold me to it, but I think if you flash Jasmine ROM version 4.0 it'll have the 5.1.1 firmware.

[Help] Install twrp in Galaxy s5 sm-g900v 6.0.1

Hey there I just got a new samsung galaxy s5, and I have been searching on the internet since yesterday, and haven't been able to find a thread that gives me information about installing custom recovery or installing a rom based in stock without any bloatware.
My phone is the samsung galaxy s5 sm-g900v (not rooted, i haven't been able to do it, maybe it's not posible yet )
android 6.0.1
kernel version 3.4.0
So my questions are:
Can I flash the twrp.tar file with odin?
Is there anyway to install a rom based in the stock of samsung but without bloatware?
And finally, can I root android 6.0.1 in my verizon s5?
Thanks in advance

you have alot to learn my friend.. if you are on 6.0.1 i dont think you can downgrade. you need to be on a 5.0 and then root then if you have a samsung board you can unlock the boot loader to install TWRP if its a toshiba you cant..

I just got the s5, but i get rid of it,im back on my old lg g2, seems it was imposible to install a clean rom on that device.

6.0.1 is downgradable. If you had a 15 chip then you could get TWRP. Even if you had an 11 chip you could still flash a debloated rom on Lolipop.

I've searched but I'm lost on where and how to downgrade 6.01? Is it just flashing over a 5.0 ? or is there more to it because it's new? And where can you find a guide for rooting 6.01 or downgrading it and then rooting?

I already gave the phone to my gf, but what would happen if I try to flash a stock based debloated rom with my pc? I mean flashing the debloated version of 6.0.1?

Flash a G900V 5.0 Lollipop Odin TAR. If you have a CID 11 chip then you can either:
- Downgrade to lollipop and stay rooted their.
- Stay / upgrade to marshmallow but not have root.

you can downgrade from marshmellow to lolipop however you cannot downgrade to kitkat due to the fact that the bootloader is different

I advise you DO NOT make move to unlock bootloader on locked device.Like install 900f roms 900f kernels. Because i tried this **** and my s5 is turned to trash. Do not try belive me.

Why are you advising those with a locked bootloader not to unlock it? If you have the right emmc, there are like 4 different methods to do it. It's simple!
