[Q] Going from 4.3 to 4.4,Stock and Bootloader

Hi all i need some quick clarification,
1) I am full aware that if you purchased a Note 3 on 4.3 and you updated to stock via either OTA, Kies or Odin the bootloader is upgraded and you cannot downgrade to 4.3 stock.
2) So my question is if you are stock 4.4 and install root, install custom recovery, Can you still downgrade to a 4.3 rom via custom recovery? or will it not allow me to downgrade at all?
3) Finally You can't downgrade to a 4.3 bootloader correct?

1) correct
2) 4.3 kernels do not boot with the 4.4 bootloader, so no
3) correct

[Q] upgrade question

I have a stock, but rooted, AT&T Galaxy S3 4.1.1 -I747UCDLK3- with ClockworkMod Recovery v6.0.3.1 and would like to upgrade to 4.3. After reading the posts regarding updating I'm a littler confused. I was wondering 1) can the the bootloader be updated with CWM or does it have to be Odin? 2) Is there a specific order that the updtaes need to be done in (For example does the bootloader have to be updated before the ROM. 3) any tips would be appriciated

Any particular reason you want to update the bootloader? Is it to install custom ROMs or modem?
I'm running a 4.1.2 bootloader on an i747m with a kit kat ROM.

Every thing I've read so far says the bootloader has to be updated. I was hoping to keep the stock AT&T ROM and just root it to remove the bloatware. only upgrading for Gear compatibility.

Just upgrade bootloader to mj2, baseband to mjb. You'll be fine long as it's a AT&T i747.

Can't flash Liquid Smooth ROM

Hi first of all I want to ask that I had stock 4.1.2 when I bought the phone, rooted it, flashed mj5 bootloader and successfully flashed the xperia z-ized rom based on 4.3 on my N7100. Then I wished to switch to dn3 rom but I still did not like it so I reverted back to stock 4.1.2 and updated to stock 4.4.2 via OTA updates. My question is, while updating via OTA to stock 4.4.2, can it be possible that I lost my mj5 bootloader and it was replaced by samsung's proprietary bootloader?
After using stock 4.4.2 I thought to check out the LS rom so I rooted, flashed philz recovery but the ROM does not boot at all and while trying to revert back to stock 4.1.2, ODIN displays the fail message. What did I do wrong and what should I do to overcome this? Thanks.

You've locked your bootloader because you upgraded to latest official which also comes with Knoxx.

[Q] Downgrade 4.4.2 to 4.1.1 to unlock

Is it possible to downgrade from 4.4.2 to 4.1.1 to unlock the device?

You just flash the 4.1.1 then probably have to flash your bootloader if it doesn't boot and then flash the jl2 radio

Hi, I have a custom rom, the galaxy project 4.4.2. What I need to do to unlock the phone?
Can I downgrade to a custom 4.1.2 via recovery, and apply the unlock tutorial?

Correct me if I'm wrong, It's the bootloader that has to be downgraded in order to unlock using the hidden menu. But with devices that took OTA updates 4.3 or later, downgrading bootloader will brick the phone. I'm also looking for an unlock option but no luck so far because my Note 2 has OTA 4.4.2. Does anyone have better information about this?

stock s3 i747 4.1.2, what should I do first? I want update, root, xposed in the end

Hi there, just factory reset my i747 s3 att phone. i am on 4.1.2.
Should I root first with chainfire easily or should I update first? I dont even remember how to update this phone from stock. I would like to be at 4.4.2 or above (or are any of the newer versions good, 5/6 etc?) with root and xposed installed in the end. What should be next steps be?
thanks!

Moved to Q&A

If the phone is not sim unlocked, I would flash a stock 4.1.1 ROM from sammobile.com using Odin and use the free method to sim unlock. I would then run OTA updates until the phone is running the latest stock ROM. Running OTA updates is the slowest but easiest method to get the phone running the latest modem and bootloader. Many recent custom ROMs require the latest bootloader and modem to function.
