how do I return to Stock? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Im running stock tmobile rooted with twrp.
Im on COG2.
Cant find the thread to return to stock, remove root & twrp
I want to go to complete stock and upgrade to DOK2
Thanks in advance

Just do a google search for stock cog or dok firmware and Odin it over, backup anything you want to save first though.

i used a few hours ago the samsung smart switch to upgrade from cog2 to dok2. No issues it removed twrp and root...as expected.
going to flash custom kernel to gain root.
Thanks!

[Q] I Want to get back to stock rom?

As the title stated i want to get back to samsungs stock rom and kernal so i can upgrade my phone to 2.3 and get my warranty back.
First of all i need to disable the lagfix and the tweaks of course but after that should i flash back to samsungs original kernal or should i flash back to stock rom first?
My kernal version is:[email protected] #14(2.6.32.9)
Rom: I900XXJPY 2.2.1
Dumb question but i can't just upgrade my phone to 2.3 via the phone's self updater. I just want to be sure.
You don't give a ton of detail here. The first step would be to find a stock rom for your device and region (2.2.1, 2.2, 2.3 all would be OK) on samfirmware.com or ramad's collection here on XDA. Then flash with Odin.
Any stock rom that is right for your location should then update to the latest when you connect to kies (or so I hear I don't use Kies..)
It will contain a stock kernel so don't worry about that. Note though that if your phone is really screwed and that is why you are flashing a stock rom for warrenty then a custom rom might boot up but a stock rom may not.
If its just for resale then you should be good to go.

Thanks for the help man.. My phone is not screwed up but i'm starting notice that it is starting to "fall apart". So that's the reason i want my warrenty back.

[Q] At&t Note 3 bootloop/flash stock help

hi everyone, im a newbie and im having a little trouble understanding and fixing my phone.
so ill start at the beginning, i bought a note 3 from at&t N900A and then moved out of the US (after contract expired and i sim unlocked with the code they gave me.)
I could not connect to at&t servers from outside US to OTA update. (i dont remember if i was mj5 or mi9)
So i learned about rooting while trying to update and decided to use kingo root app and got root access
then i installed safestrap 3.71 for a custom recovery, then i backed up my stock rom and made a new rom slot. Then i resorted my stock rom to rom slot 1.
this is my mistake: i flashed the knoxraid rom from here
http://galaxynote3root.com/att-galaxy-note-3-roms/knoxraid-kitkat-rom-for-att-galaxy-note-3/
however i forgot to do the data/factory wipe. To make matters worse i realized this and pulled the battery out after about 20 seconds (the download bar was about 10% complete)
when i put the battery back in the phone went straight to recovery (recovery and download mode were the only ones working)
i started panicking as this was my first time rooting/installing roms and tried to find a solution
i found one and used this:
http://www.droidviews.com/how-to-unbrick-att-galaxy-note-3-sm-n900a/
i flashed all the files correctly and odin got to about 95% and the said FAIL
i panicked again when i turned my phone on and it went to an error screen saying firmware upgrade incountered an issue etc.
before i harm my device further i would like to know what to do (i can still get to download mode)
odin mode say it is A2 so i belive that is mj5
i want to know: should i reflash stock mj5, and if so please provide link
should i do this: http://forum.xda-developers.com/showpost.php?p=48243768&postcount=1
should i use the N900AUCUBMI9_OneClickBin.exe
or should i flash nc2 files found here: http://forum.xda-developers.com/note-3-att/general/n900aucucnc2-odin-files-t2838117
will the nc2 kitkat brick my device? keep in mind it is running A2 which im sure is mj5
Thank you everyone in advance
NC2 won't brick your device, but it'll upgrade your bootloader to A3 which will prevent you from ever downgrading back to MJ5 (not that you'd want to anyway). I'd just go with NC2 since it's rootable with TowelRoot anyway. Also, in your case I'd recommend using the 4-file method rather than the 1-file method since it's an upgrade from 4.3 rather than just a restore to stock 4.4.2.

You might want to consider adding the Pit file too to repartition your phone just in case anything got messed up in the failed odin flash that would definitely clean everything up. It might be overkill but I don't think it would hurt to do since you're doing a factory reset with the 4-file install anyway

Question about flashing N910TUVU2DOK2 Firmware/Baseband

I'm running an N910T with Rapture 8.2. As this ROM apparently isn't under development or support any longer, I'd like to move to another ROM that is. I'd also like to update my baseband to N910TUVU2DOK2. To update the baseband, do I need to ODIN back to stock and upgrade from there, or can I simply ODIN the baseband and move forward? I believe that I'm currently on COG1, but can't tell because I'm running a backup just now.

You always need to Odin to the full firmware that matches the ROM you want to use. Please keep in mind that once you go to 5.1.1, you'll be stuck on lollipop bootloader.

Thanks! Should I ODIN to stock, or straight to the new ROM? I rooted and flashed my old note 2 gobs of times, but the note 4 I'm not that sure about.

You use Odin to put stock firmware on and to root and add TWRP. You use TWRP to flash ROM's.

I have gone back and forth between 5.1.1, 5.0.1, and 4.4.4 roms by using odin to flash the COG2, COD6, or ANK4 firmware first, then using odin to flash autoroot and TWRP. Then use TWRP to flash the desired rom. I have no problem going from lollipop to kitkat and back. I have used the COG2 firmware for all the 5.1.1 roms, like Texxodus, Resurrection, Slim, CM12, etc. I have used COD6 for 5.0.1 like Alliance, I have used ANK4 for Firekat. I have never had a problem reverting between any of them.
Why is DOK2 different? Does it trip some kind of hardware switch, like knox? If I was on it and used odin to flash, say, the kitkat firmware, what happens? Does odin no longer work when you're on DOK? Does it crash? Does the flash appear to work but it stays on DOK? Does it flash the firmware but bootloop? Does it brick the phone? I always thought that odin flashed firmware to the lowest level so that as long as you could connect the phone to a PC and had a good firmware load, you could restore it.

Going to lollipop

So I'm in nc2 and wanna jump up to a new rom. Thinking alliance, biggins or Arya mod. What all are you guys running and how'd you do it? I can seem. To find the thread on how to do it. Did you use safestrap or flashfire? If you used flashfire, how do you use that? I must have the stupid on the search here lately...

You got it easy.
Root with towelroot, Install SuperSU, Install Busybox, Install Safestrap 3.75. Done.
Reboot to safestrap and flash what you need. Don't worry about flashfire, you probably won't ever need to use it. Or at least out of my experience I've not had to use it. (For the note 3 that is)
I'm much more versed in rooting and roms than you assume. I'm on dk7.1 and have odind many times. Just curious as to the actual process of switching to lp. And what would need done to go back to kk if necessary
Sent from my SM-N900A using Tapatalk
Before you flash, just back up your kk rom. And then when you flash the rom, make sure to flash the kk kernel so safestrap is still accessible

It doesn't matter what ROM you are currently on you can always odin back to NC2 and then upgrade to NL1 or OC1/2.
Examples:
If you're on OC1/2 and want to go back to NL1, you would full odin back to NC2, re-root and such. Then flash a NL1 based ROM.
If you're on NL1 without root and want OC1/2, full odin back to NC2, re-root, etc. Then flash a OC1/2 based ROM.
I've never even head of nl1. And Don you need to flash the kernel and radio or is just the kernel necessary?
Sent from my SM-N900A using Tapatalk
It depends on the ROM you plan on going to.
AllianceROM v12 doesn't require a kernel flash
UrDroid Stock Deodexed requires an OC1 flash (optional OC2 patch available)
OC1 is 5.0
OC2 is a security patch for OC1
NL1 is 4.4.4
NJ2 is 4.2.2

Are you sure about alliance? I tried to flash that and got stuck on the Galaxy Note 3 screen
Sent from my SM-N900A using Tapatalk
I've ran Alliance v12 more than a few times on both my phone and my girlfriends phone, I've not once had to flash a kernel if you get stuck reboot into the stock recovery and look at the top, if it says OC1 then your on the right kernel. But flashing it definitely won't hurt anything.
This is taken out of the changelog for AllianceROM v12
ROM will automatically flash OC1 Kernel so after install, just hit reboot.

Also make sure you're on version 3.75 for Safestrap.
i have done this many times over within the past hour and safestrap wont install... i have used these exact steps b4 last year but it just wont work now....

N910T Back to Stock... Help Please.

HI Just wanted some advice. Im on 6.01 Overdrive rooted but would like to go back to stock as I feel I'm not using any rooted featured and also I'm getting problems with Oculus etc.
My Question is what's the best Firmware to flash in Odin that if I decide to go rooted again it won't block me or upgrade my bootloader. I'm on Baseband PE3 at present.
Do I need to wipe anything? Or is an Odin Flash enough. Thanks
I use epg2. You can flash the dev base for that. I pulled the boot.img from it and flashed over to remove root. The 910t had guides to get you back to lp from anything before pj2. Haven't bothered upgrading past that point.
