You can flash any custom rom you want ie: Kitkat/Jelly bean/AOSP . but you cannot downgrade your phone using odin mate , You need to download a custom rom and then flash Philz recovery or TWRP , Do a nandroid backup and do a fullwipe and flash the rom.

[Q] Reverting back to your original firmware

I've just flashed Echoe 2.1.1 rom over my I9505 and later there is a new firmware update from Sammie - MI1. Will I brick my phone if I flash the new official firmware using Odin? Are there any method where you can safely downgrade to your original rom?

You can Flash Stock firmware using Odin I don't see any issues and if u have a nandroid backup of your old ROM that will also work just fine
B4 doing anything if u have not done Do take a efs backup and nandroid backup and keep it safe somewhere on Pc/ Sd card
and after flashing Stock firmware I suggest full wipe / reset for error free experience

Hi ,
Once you upgrade your bootloader is not possible to go back to 4..2.2 (or 4.3)
You upgrade your bootloader if:
Flash a stock rom 4.3 and higher
you do not upgrade your bootloader if:
root , install custom recovery and flash a custom rom , there are a few good rom based in samsung stock 4.3 and 4.4.2 you can try them see if you like them and if you don't you can always flash stock 4.2.2 and be as you were
Ok, so essensialy i can't downgrade the bootloader to 4.2.
but a official 4.2.2 firmware (without knox) will work on a 4.4 bootloader ??? (again i don't care about knox working or not)

It has been done to 4.3 in this thread: http://forum.xda-developers.com/showthread.php?t=2744061
they have flashed a 4.3 ROM without bootloader over a 4.4 ROM so the result is a 4.3 rom with a 4.4 bootloader

HI ,
Mate if you flash with Odin or OTA (kies) you will change the bootloader , ok? so once you have a 4..4 bootloader installed there is no way to install back a 4,2,2 stock ( official ) firmware , 4.4.2 official firmware includes 4.4.2 bootloader and flashing an older bootloader than the one you have is not possible (yet)
your options are:
4.2.2 bootloader
stay there do nothing
Upgrade to official 4.4 and not be able to downgrade to 4.2.2 official
root , install CWM and install any custom rom you want ( 4.2.2 , 4.3 or 4.4.2 and 4.4.4 ) and if you do not like any of them go back to official 4.2.2
Once you upgrade to official 4.4.2 there is no way to go back to official 4.2.2 , the only way to go back to 4.2.2 would be with a custom rom

If i understood right, you are saying that can be done if i flash a custom rom as intermediate step between official 4.4 and official 4.2 ??

No . I did not say that
Once you are in an official 4.4.2 firmware , the only way to use a 4.2.2 rom would be by flashing an un official 4.2.2 custom rom

Hi,
I guess you mean that you have stock 4.4.2 and want to install a custom rom 4.2.2 , i would try first rom as it is , if you have signal problem i would try a different modem then.
Downgrade from stock 4.4.2 to stock 4.2.2 is not possible at the moment

[Q] Do I need to upgrade bootloader before installing custom rom?

Hi there,
just got my hands on this international Note 3 and looking to root it and install a custom rom. I think I got all the information and softwares on how to root and flash custom recovery. but I'm just not sure if I need to upgrade my bootloader before flashing a custom rom? I don't even know what bootloader i'm on. but I do know that I'm still on 4.3 stock.
please let me know of anything that I need to do before flashing a custom rom.
thanks so much!

ok thank you!
I tried using kies to upgrade to 4.4 as i figured that would be the easiest way, but keep getting an error, so I do need to flash stock using odin. but I'm so confused as to which one to download. right now when I fire up kies, it shows this:
current firmware version: PDA:MJ7 /PHONE:MJ7 /CSC:MJ6 (ZTO)
Latest firmware version: PDA:NG3 / PHONE:NG2 / CSC:NG3 (ZTO)
can someone let me know which firmware I need to download from sammobile.com?
thanks so much.
oh please disregard. I didn't know sammobile.com had a place where we can search by country, etc. it's really cool. so I found what I needed.
thank you.
I was able to do an OTA update, so now I'm on kitkat 4.4; so my question is, now do I need to do anything for preparation in order to root?
thanks.
nothing to do
flash cf auto root and you re done...
thank you! you guys are great!
