what's up everybody quick question, I have updated my phone to 4.4.4 and hate it. my question is because the t mobile mote 3 is an unlocked boot loader can I downgrade to 4.2 or 4.3? Odin of course.
Here is a sreen shot of what i got now.
Downgrade of the bootloader and rom is not possible once updated to 4.4 on the note 3 however you can downgrade the kernel via Odin to NF4 NE6 OR NB4.
I'd suggest just go into factory recovery mode and do a factory wipe along with a cache wipe

so from what i understand about updating the bootloader to MJB, i can only flash custom ROMs based off TouchWiz 4.3 and up, correct?
but AOSP/CM based ROMs can be any version? as long as the bootloader is supported on that ROM? and worst case scenario, i can flash CM10.1.3 (Android 4.2.2)?
currently i'm on S3Rx 2.2, which uses Android 4.1.2. there would be no point in making a nandroid backup, since the bootloader would be updated and i could no longer use this ROM, correct?
i was going to follow this guide:

and then use this ROM:

***************SOLVED:***************
flash the MJB bootloader via custom recovery following the above guide.
then flash the MJB modem via custom recovery with this guide:
http://forum.xda-developers.com/showthread.php?t=1831898
reboot to phone (i did, not sure if necessary tho)
then reboot to recovery, flash new custom ROM.
done.
a mistake i did was i only flashed the bootloader first. rebooted, then flashed new ROM. in which case i had no wifi and data. so i flashed the modem, rebooted, no wifi and data still. rebooted into recovery, factory reset, wipe cache, wipe dalvik, and everything worked fine after that.

You could install the MJ2 bootloader and MJB modem which would allow you the ability to go back. Once you are on MJB bootloader, there is not going back without bricking. If you ever find that you need to revert back for any reason you will be stuck. If this does not bother you, then go for it.

i read somewhere that MJ2 was unstable or something. cause it was a preview leak?
but back to my first question, MJB makes it so i can only flash TouchWiz-based ROMs 4.3 and up? so i will be good to use AOSP-based ROMs of any version?
For clarification purposes:
If you upgrade to MJB you will have the 4.3 KNOX apps (OS) and KNOX bootloader (Firmware). You can easily root following this guide: http://forum.xda-developers.com/showthread.php?t=2538991
Once rooted by following the guide noted above you will have the 4.3 KNOX (OS) removed BUT not the KNOX bootloader. With the KNOX bootloader you will never be able to downgrade the bootloader. What that means is that you can never use odin to flash an older firmware or you will brick!
Now that your MJB is rooted you can flash any ROM you want 4.1.2, 4.2.2, 4.3, 4.4.2 since most custom ROMS dont include the bootloader in the ROM package.
Hope this clears things up?

Yes it does! Thank you!!
I'm on the latest bootloader and modem and I haven't had any trouble flashing any aosp based roms. Only thing I was told you might have to take the bootloader line out of the update script, but so far I haven't had to at all.

just wanted to clarify, i'm already rooted, so i was going to follow the guide from my first post (since this guide has ZIP files i can flash in CWM):
http://forum.xda-developers.com/showthread.php?t=2321310
Flashing in recovery
If you've downloaded a flashable .ZIP from above, copy it to your SD card or internal storage. Reboot your phone into recovery mode (you can do this by holding "Volume Up" and "Home" while powering on your device; let go of the buttons when you see "Recovery booting..." in blue text in the top left of the screen) and install the .ZIP as an update. Reboot, and you're done.
Note: After flashing in recovery, you need to reboot before you (and ROM installers) actually see the new version number.

would i reboot first, then flash a new ROM?
or should i flash the bootloader, then immediately flash the new ROM?
UPDATE: so i ended up just following the ZIP file guide:
http://forum.xda-developers.com/showthread.php?t=2321310
and now i don't have data or wifi. i flashed the modem from here:

ANOTHER UPDATE:
after i went into recovery, factory reset, wipe cache, wipe dalvik. the phone is recognizing wifi and data now. woo!
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
Sent from my leanKernel 2.2 powered stock 4.4.2 SM-N900T
If u have the w8 Canadian variant u can downgrade your bootloader.
thanks

is 4.4.2 that bad for the n900t?
it seems people are trying to avoid upgrading the bootloader. and are trying to downgrade if already on kitkat. whats wrong with the kitkat bootloader?
Wanting to drop stock(latest) back onto my phone as the person buying it wants that. I want to say I remember reading I needed a newer bootloader for 4.4.2. I got my device on launch and got tired of waiting and went to CM11.
What if anything other than clearing data/cache and flashing the stock deodexed/rooted ROM would I need to do? If there is a bootloader, is it a separate odin file? or flashable .zip?

If you're on 4.3 still you will have to Odin a stock 4.3 firmware on to the phone. You can not have a custom recovery on the phone so the Odin way will also replace the custom recovery with stock recovery. Then once your phone is stock, you can then take the update to 4.4.2
If I'm not mistaken, you should download the 4.4.2 fw and Odin that on you phone as well. Even though you are Odining your new fw, the phone must be fully stock or that update will still fail.

Well I was on 4.3 stock then went to Cyanogen 4.4.2. I've now got the deodexed/rooted stock 4.4.2 from the forum here and was able to boot it using leankernel. It works and the buyer is satisfied with it. He know how to flash updated ROMs so he can change later anyway. Thanks for the response though, I was thinking noone was gonna answer.

If you want the newest/latest official stock N900T KitKat firmware why not do the following:
You need to download and Odin flash the official stock KitKat N900T NE6 firmware.
Here is the direct fast download link for it:
http://www.androidfilehost.com/?fid=23501681358537528
The above zip file also contains Odin, CF-Autoroot and TWRP 2.7.0.1 recovery.
Be sure to go into recovery before Odin flashing NE6 and do a factory data reset
and a full wipe. Optional: Then Odin flash cf-autoroot and the TWRP 2.7.0.1.
If you want more information and or instructions here is the link:
http://forum.xda-developers.com/show...60&postcount=2
If you want the older official stock N900T 4.4.2 NB4 KitKat rom you can
download it from: http://tekunix.com/downloads/TMB-N900TUVUCNB4-20140305155920.zip
and Odin flash it instead of the stock NE6 official N900T firmware.
Both the older and newer official Kitkat stock roms come with the required bootloaders/baseband.
Good luck!

So clear data/factory reset and clear cache in recovery. Reboot into download and flash NE6, then cf-autoroot, then TWRP? I didn't see you say exactly when to flash NE6.
hi guys new to the galaxy phone and i have been looking into flashing a rom. i have done all the ground work root and custom recovery but now im trying to flash a rom and i get errors. i looked it up to a point where everything i do want to flash requires a 4.4 or 4.3 update and i am stuck in 4.1 is there any solution to this like start from an older rom and work my way up to a current rom. would that work or odin the phone to a current update if possible to find the update. what options do i have ?
not sure if this is the correct thread
Well I would just flash via Odin up to 4.3 because most Roms require the 4.3 boot loader so yea
Sent from my ATT Samsung Galaxy SIII using TapaTalk
I recommend you not update to the 4.3 bootloader as the 4.3 bootloader can cause problems when trying to flash back to stock. Once you're on a 4.3 bootloader, you cannot downgrade to a lower version. Most ROMs seem to work fine with a 4.1.1 or 4.1.2 bootloader.
If you have the att s3 (i747) and not the Bell/Telus/Rogers s3 (i747m), you cannot use Odin to flash a stock 4.3 ROM as it does not exist. You would need to flash a version of 4.3 that has been custom compiled for flashing via Odin.
I would download the latest version of Philz Touch and flash the tar version via Odin. Copy a custom ROM to your SD card, boot to recovery, wipe cache, Dalvik, data, and flash the ROM.

I've done a bunch of searches on both XDA and google but haven't been able to figure out exactly what all steps I need to take to upgrade from 4.3 to 5.0 while keeping root or re-rooting.
I have downloaded the 5.0 stock firmware for my SM-N900T and have odin on my desktop PC, but am afraid to flash it. Do I need to flash 4.4 first and then 5.0?
No you can go straight to 5
Try this rom.
http://forum.xda-developers.com/showthread.php?t=3021965
If you flash from 4.4.2 to 5.0 via Odin, you may encounter a bootloop which means you'll have to boot into stock recovery and wipe cache. If that doesn't work, you'll have to try a full factory reset/wipe.
