WARNING! THIS WILL BREAK YOUR WARRANTY! I HOLD NO RESPONSIBILITY FOR BRICKS, BOOTLOOPS, ETC. IF YOU END UP HAVING A 500 DOLLAR BRICK, IT IS NOT MY FAULT AS YOU ARE THE ONE WHO DECIDED TO DO THIS PROCEDURE!!!!!!
THIS GUIDE IS FOR THE SM-N900. IF YOU TRY THIS ON ANY OTHER DEVICE, YOU WILL 99.99999% CHANCE OF BRICK!!!!(NO SM-N9005, N900V, ETC.)
Hey guys, so many of you are wondering if you can downgrade from 5.0 to 4.4.2 or from 4.4.2 to 4.3. I see many people say this is not possible, but it is!
you'll require:
A windows machine with a sensible version of windows (no windows 95, 98, etc.. )
OR
A mac that either dual boot windows and os x or running windows in a virtual machine (this is what I'm doing)
Odin - Download here
A SM-N900 device running 5.0 or 4.42
A stable internet connection
USB Debugging enabled on your device. If you don't know how to enable it, check here
Boot loader: http://www.mediafire.com/?edp1iw3qzwhtoij (Only if you're downgrading to 4.3!)
7-Zip - Download here (WinRAR WILL NOT work)
SamFirm - Download here
And last but not least....
A brain
Okay, let's get on with this.
STEP 1:
Download and install everything I listed above!
Back-up all data on your device.
Unzip SamFirm and Odin to respective folders on the desktop
Open SamFirm by double clicking on the exe
You will be greeted with the application. You now need to specify what firmware you want to download. Enter the model name as SM-N900 (All caps!). Next, you'll be prompted to enter your region. For downgrading to 4.3, enter XFU as the region. For 4.4.2, enter BTC. Don't check binary nature and select auto mode. On the right, select decrypt automatically and then press download.
The firmware will now begin downloading. Wait for the download to complete.
STEP 2 (Only if you're downgrading to 4.3! If you're downgrading to 4.4.2, go to step 4) :
Power off the device. Boot to recovery by holding home, power and volume up at the same time. Do a factory reset. Power off the device again and boot to download mode by holding the volume down, home and power buttons. You will be greeted with a warning. Press continue. Open odin and wait for odin to recognize your device. Select the BL tab and select the bootloader.tar that you downloaded. Next, go to the options tab and unselect auto reboot. Then start the flashing process. DO NOT SHUT DOWN YOUR COMPUTER, PHONE OR UNPLUG THE DEVICE DURING THIS PROCESS!
Once the flash has completed, shut down the device and reboot to download mode.
STEP 3:
Next, take the decrypted zip you downloaded. Open the zip with 7ZIP. Extract the tar.md5 file and open that with 7ZIP. Extract the contents of the tar.md5 file. Delete the sboot.bin, then rezip. Select all the extracted files and right click. Click 7-ZIP > add to archive. Select archive type as tar and then recompress.
STEP 4: Go back to odin, and press reset. Go to the AP tab and select the new tar you just created or if you're downgrading to 4.4.2, select the tar.md5 extracted from the zip. Wait for odin to process the file. It may appear that odin has hanged. This is normal. Wait for it process the file. This time, select auto-reboot from the options tab. Then, start the flash. This flash with take a minute or two. After it finishes flashing, the device will automatically reboot. After the splash screen, it may appear that the device has hanged due to the black screen. Wait for a few seconds, and the startup animation will play as usual. At this point, you should be successfully downgraded!
NOTE: IF YOU HAVE MOBILE NETWORK OR IMEI ISSUES, THEN FLASH THIS OR THIS MODEM IN CWM OR TWRP
If this helped you, please press thanks.

How could this be adapted to work on N900t? And do you have pics to confirm that you got bootloader back to 4.3? I thought that was not possible

Sorry the n900t is a snapdragons device so it will not work ��
I am on kitkat right now. I upgraded from 4.3 to 4.4.2 again so I cannot 0ost the pictures. Sorry about that.
Thanks for the quick reply. But I thought it was impossible on all note 3's so it was worth finding out
Bootloader download page asks for decryption key. Please upload it to another file hosting site. Thanks. And as you have downgraded to 4.3 is the battery life better than kitkat or lollipop?

Sorry about that I updated the link. Battery life on 4.3 was good.
Followed all the instruction properly. Flashing Bootloader failed the first time as I used Odin 3.7. Flashed with Odin 3.10 and it worked. Flashing the repackaged tar file didnt work twice. It always got stuck while flashing. Then I used Peazip to repackage and it successfully flashed with Odin.
OP please upload the modem to another site as well. Am stuck without mobile network :/
Tl;dr Successfully downgraded to 4.3. Almost.

The steps i did ->
Downloaded Firm from sammobile -> SM-N900_XFU_1_20131129160104_fifz3b44bv
Downloaded 7 ZIP
Downloaded Bootloader.tar (From the post)
Flashed Bootloader.tar -> OK
Open firm with 7 zip, erased sboot.bin -> recompress to tar -> OK
Flashed recompressed TAR without sboot.bin -> OK
Firts boot -> Black screen with red letters saying something about a Kernel Error
Second boot -> Shows "Samsung Galaxy Note 3" (like usual) reboot, shows the samething again and reboot and then power off
I tried to go into recovery mode -> FAIL
Tried to go into download mode -> FAIL

Try a factory reset and or flash stock firmware .
downloaded twrp 3, was running 5.1.1 on my phone and rooted it. tried to flash a rom and got stuck in a bootloop, now I cant boot into twrp, or anything for that matter. All i can do is hold volume down and power and home and try to ODIN a new bootloader or such and it just fails. what do i do? but when I try to boot into TWRP it goes into a blueish screen with a White exclamation mark saying "An error has occurred while updating the device software. Use the Emergency recovery function in the smart switch PC software. I tried to do that but it didnt even recognize the device. At this point i dont care about the data, I just need a working device
Okay, so I attempted to unroot and flash the stock 5.0.2 software and I got a error on the download screen. It says SW REV. CHECK FAIL. DEVICE: 3. BINARY: 1.
If you have no knox install MM official then flash this kernel tar file (AP) https://drive.google.com/folderview?id=0B40ItdHKfkyQcTA5bnRPWDg0X28&usp=drive_web#list it will boot to mm 5min :good:
Btw you cann downgrade from 5.1.1 to 5.0.1 you just go up not down

Happened to me a lot of times in the past few days trying to get MM, for some weird reason flashing Unikernel always works for me (takes me to recovery screen after, then i select 'reboot now'), and all my data, apps etc are still there

will try and update. thank you. didnt work.
Okay guys so now I need a ROM to flash using ODIN. I tried to download from sammobile but the speeds are too damn slow. What I tried to flash was this file " G920TUVU1AOCG_G920TTMB1AOCG_G920TUVU1AOCG_HOME.tar.md5 " and i got the error 3 to 1.
Download Samfirm from here, XDA itself.
Run samfirm, enter model as G920F and your region code.
It will download from Samsung servers, so high speed.
Now flash using Odin the downloaded file by putting the phone in download mode, (vol down+home+power on).
How did it happen?
Did you try to flash the VOD 6.0.1 and got stuck towards the end at hidden.IMG failing the process?
If yes, then its a two minute job. Just open the 6.0.1 tar archive and look for hidden.IMG extract it anywhere and rename it from "hidden.img" to "hidden.img.tar".
Note flash this hidden.img.tar as AP in download mode, your phone should boot.
I rooted my phone a while ago in like April and for some reason it became unrooted a couple days ago for no apparent reason.
I tried Autoroot without success so then I tried TWRP without success because when I tried to boot into recovery I got a big red screen.
"****" I said but was able to boot up and decided to do a factory restore and then restore the firmware to stock with odin
This proved to be a huge mistake because after factory resetting the phone, it won't boot or go into download mode. It just shows this:
"Recovery not standard enforcing" then

Anything I can do or should I just sell it for parts at this point?:
No, it is hard to brick... but you have to follow the instruction carefully... your error is the consequence of ignoring...
Take a breath and start from the beginning... first install via odin a clean original image
How do I install an image with odin if the phone won't go into download mode?

Hello,
1. first, try the normal procedure by pressing POWER+VOL DOWN. This will force your device to hard reboot. When the screen comes black press immediately POWER+VOL DOWN+HOME to get on Download Mode
2. Install Odin on your windows and download the official ROM from the SamMobile's site
3. Not that much ahead the last step. Just open the correct files inside the ROM folder with odin and flash it
| IMPORTANT |
If you really can get to Download Mode DON'T forget to flash the BT file (bootloader) inside the ROM's folder. In other words, flash every file inside that folder and your device will boot
There is no chance of getting bootloop with official firmwares. So just be patient in the very first boot
Hello everyone. I tried to turn on normally my j110g. It does enter the download mode but appeared weirdly. No android icon. Just this texts below appeared on the left side of the screen. I tried to flash the stock rom but didn't succeed. When i tried to enter download mode using the usb jig, it goes directly to factory mode. What could be the possible problem and i hope i could get some answer here. Thanks.
ODIN MODE (MULTI CORE DOWNLOAD)
PRODUCT NAME : SM-J110G

In such situations your main hope is to flash stock rom through the Odin,
How you trying to flash stock rom? Is you got success? What is the custom status for system?
Is your phone rooted or custom recovery installed?

That screen is for flash external things like custom recovery, stock firmware (original), bootloader, Modem etc.
This is not for downloading with internet,
& for Odin- first you need download stock firmware of your device the from sammobile website, downloaded file is in Zip format, have to extract it first you will get 'your firmware name.tar.md5 file , install usb driver on PC, then open odin 1st, then connect mobile in download mode you should see in above column 0:[COM-] & in log you will receive 'Added' message something like this it will confirm that your mobile is connected successfully, then in Odin select PDA or AP section select your extracted tar.md5 file, wait sometime for loading tar.md5 file in odin again you will see the file is added in log section then finally you can hit start button...
Wait till receive pass message or this will reboot automatically your device.
Best luck

i agree with you, the only way to solve it , is change your emmc , my phone have the same problem and i couldn't flash it with odin even with 4 file firmware
My note 5 has been in a sort of root/not root limbo where I haven't bothered to update or do anything with it and I just want to get it back to stock. All I remember is that I need a stock rom and a kernel, but it's been so long that I don't remember everything. Anyone wanna help me get back to a usable stock state?
tldr: You will need a computer for this, download n920T Stock firmware from here and then odin it.
Preparation Steps:
1) Back Up all your Personal Data( if you are running TWRP it is recommended to Backup EFS partition and keep a copy somewhere safe)
2) If you are previously running a custom rom you should wipe your System and data partition in TWRP otherwise it will not boot after this.
Actual Steps:
1) Download the stock firmware for N920T only from here .
2) Download Odin from here
3) unzip zip file and run Odin.
4) unzip the stock firmware and extract the ".tar.md5" file.
5) now in Odin on the right side, click on AP button and select the file you extracted in step 4. (if odin goes unresponsive leave it for 5 minutes it will be back after fully loading )
6) assuming you have backedup all your important data now turn off your phone and restart it in download mode by pressing (power and home and volume down button)
7) Press volume up if it gives a warning and enter download mode.
8) now connect your phone with your computer and you will see on top left a box in Id:com will turn blue with your port number written on it.
9) DO NOT change any setting from options tab.
10) Press Start you will see progress and once its done, phone will restart.
I keep getting an invalid error when I try to download that firmware. I crashed my n920t and been trying to flash a firmware to get it back but the only thing working or flashing in Odin is twrp. but I can't get it to boot in twrp. any ideas?
