I am on a Cyanogenmod Nightly (4.4.4) and I would like t flash back to stock firmware. The highest available stock firmware for my phone is 4.4.2 is it safe to downgrade to this firmware because the bootloader is the same? (I have a SGH-T999 on Mobilicity). The reason for my downgrade is that I am trying to unlock my phone and the USSD codes are not working on the Cyanogenmod dialer.
It'll be fine. Just don't forget to factory reset and back up your data

Okay, so my phone is currently running 4.4.2 Cyanogenmod right now, I had to find out the hard way that I cant jump back to 4.3 due to the bootloader but will it be possible to install the stock 4.4.2 safely once its released? Or is there a way to go back down to 4.3 that I'm missing..

Don't know how you got the impression you can't go back to 4.3 from Kit-Kat based CM. CM, like most stock ROMs, doesn't come with its own bootloaders but relies on manufacturer's bootloader to run. If you went to CM from stock 4.3, chances are your bootloader was unaffected and still remains at 4.3. You can check what bootloader your phone is on by going to settings and seeing what you have under baseband. If it's UCUEMJB then you have the 4.3 (MJB) bootloader and you should be able to use custom recovery to flash a stock 4.3 restore image.
If history is anything to go by, you would be unlikely to get the (newly released) 4.4.2 update OTA if you are not on a full stock (or stock-based) ROM. I would, however, not be in a rush for OTA as we can always trust the good guys in the development community to come up with a manual update process shortly. If you still want to revert to full stock 4.3, then you can follow the instructions in the thread below ...

Your right!
Used the process you gave me and it worked, I had been trying to use odin but I supose a simpler solution was better. Thanks again!
I just switched from stable CM10.1 to stock 4.4.2 this week. It sucks. Performance and battery dropped drastically. Will be going back to CFW asap.
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.
i have stock 4.4.2 NF2 bootloader , what i need to do for change it to 4.3 ?
and is there any way to unlock hidden languages in 4.4.2 ?
Any attempt to downgrade the bootloader will cause a brick. You can, however, flash a 4.3 rom via custom recovery it will run on your current bootloader. Wifi may not work without using ktoonsez kernel though.

I'm currently running CM12.1 on my phone. I love it, but I want to return to stock and give my phone an "out of the box" feel, and return it to the way Samsung made it to be.
I follow the typical instructions found here, but I always get an error (no screenshot available. Sorry!). I'm running Windows 10 and I have the proper drivers installed. Is there something I'm missing?
If the phone is running a 4.3 or newer bootloader, you cannot flash back to stock using a stock rom from sammobile.
Before flashing anything, I recommend verifying the bootloader and modem before flashing anything else. An improper bootloader and modem combination could brick the phone.

Alright. Thanks. A bit disappointed, but thanks anyway. Besides, CyanogenMod isn't bad.
I was just running CM 12.1 / 13 and I was able to revert back to Roger's Stock ROM Android 4.4.2
Try Odin3 and installing the stock rom. But you should always verify the bootloader.

If the OP is running the i747, it is the the AT&T version of the s3. AT&T never released a full firmware release for use in Odin after 4.1.1. AT&T only released OTA updates that upgraded the phones from 4.1.1 to 4.4.2. In order to flash a stock AT&T 4.4.2 ROM, it needs to be done from TWRP.

hey can anyone help me? i've recently reverted my note 2 back to stock via odin and everything seemed fine. When the phone booted and i went through the setup process it always hangs. No matter what i do it always hangs. I've tried reflashing it and rebooting it over and over again but it always hangs. anyone know why this keeps happening?
Are you flashing the latest stock ROM? You're performing a factory reset before booting the ROM for the first time?

Yup latest stock rom, and before i flashed via odin i deleted my previous rom via twrp and formatted internal storage so its 100% clean
I've downgraded a Note 2 sgh-i317m to 4.1.1 from 4.4.2 by flashing a stock 4.1.1 ROM from sammobile.com in order to network unlock the phone. Flashing the stock 4.1.1 ROM tripped knox and could be installed via Odin because the 4.1.1 ROM from sammobile.com did not contain a 4.1.1 bootloader so I wound up with a stock 4.1.1 ROM on a 4.4.2 bootloader. After unlocking, I flashed the stock 4.4.2 ROM again and the the phone worked as it should.
I'm not sure which phone you have and I'm not sure downgrading and upgrading will work in your case but it's something you may want to look into.

I've managed to get the phone working (N7100) and it seems to run fine on Nougat. I did some testing and indeed it would always crash on setup with kitkat roms. I wonder why this is the case....
It is strange that kit kat causes a problem.
Have you tried using a different version of twrp to wipe the system before flashing with Odin? Can't think of anything else that may solve the problem.
