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.

I have a Samsung Galaxy S5 AT&T OA1 (G900A) and I cannot get the phone to take a custom rom flash. First I downgrade to NCE using ODIN 3.09, check install from unknown sources, then I install towelroot and successfully root the phone. Install SuperSU and update the binary, reboot, install Busybox. Shut down and go back into download mode and use ODIN to flash the OA1 kernel. I then install either flashfire or SafeStrap and then instruct them to wipe the phone other than internal memory and flash the rom zip. I have tried several roms and everytime I get back to the same thing... the default recovery screen with a dead android.
Any suggestions or ideas what I am doing wrong?

After downgrading to nce and rooting there is no need to update the kernel back to OA1 as all the kitkat roms are based off the nce build. Our you can root then upgrade to lollipop using this method
http://forum.xda-developers.com/showthread.php?t=3076803 as the devs for the s5 roms have moved to 5.0.

I have tried to do the flash several times without going back to the OA1 kernel too, but I thought that may have been the issue. I figured out quickly it wasn't.
One thing I may have been missing is that I am trying to flash lollipop roms. Is that my problem? Do I need to be flashing a KitKat rom unless I flash the rom to linked to in your post? How do I get a lollipop rom flashed if that's the issue?

You can't flash lollipop roms unless your already on lollipop. You'll have to stick with kitkat roms unless you upgrade using the method in the link that i posted. Once you upgrade to lollipop using that method you'll be able to flash lollipop roms.

Good deal. Which one did you go with. I've ran alliance, twi5ted, and TMS 2.0. I personally like TMS best. Seems like it runs smother for me.

I went with TMS 2.0, but I was hoping to get a Cyanogenmod based rom installed. I have tried several times to install the Fusion rom using FlashFire, but each time I get an unmount failed notice and have to go back to NCE.
What do you like about TMS?

First off you can't flash cyanogenmod cause of the locked bootloader. We have to stick with TW base roms. I like the stability about TMS2.0 plus the fact that the dev is still working on it. Most all the other devs have went to other phones. TalkingMonkeys is a great dev and is constantly working on mods and features.
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.
I am sorry to belabor this, but nothing I have read has explained this. All you get is that once you are on DOK2, you can't go back, but no one seems to know why and no one appears to have tried using Odin to flash a previous firmware and can answer the questions in the previous paragraph.

Try it and report back. The bootloader can never be downgraded once it has been updated but I have heard of people odining back to kitkat from 5.1.1 and them getting it to work. Not sure how it was done but they did it.

You say the bootloader can never be downgraded once it has been updated. Okay, that's what everyone says. But is it true? No one seems to know. And if it is true, why? I find this very odd that no one knows.
My current favorite rom is Alliance since for me it has the best battery life and the least lag of the roms I have tried, so I don't want to take a chance that I can no longer run it if I flash DOK2 and don't like it.

My understanding is that it's part of a new "security policy", I believe implemented by Tmo. My source of this info isn't related directly to my Note 4, but last month I Jumped my tablet to a new Samsung Galaxy Tab S2 that came loaded with 5.1.1. The day after picking it up I got a notification for a firmware update, still 5.1.1 (small size), screenshot of the "release notes" attached below. I didn't take the update and froze updates in TiBu. There's not a whole lot of development for that device yet and I think that I would have lost root if I had taken it.
I'm all for "security", but disabling users' ability to downgrade firmware hardly seems like much of a contribution to that end. IMO this is a disappointing development, and has much greater potential to affect "power users" vs. "regular users" as I doubt that a regular user downgrading the firmware on their device to their determent is something that even happens... ever.

Canadian note 4 dont seem to have the security lock on them since i rolled back to 5.0.1 bootloader but yes it wont let u roll back to any other 5.1.1 bootloader
U can try to download canadian BOE2 firmware and flash that since tmobile nd canada r pretty mch the same
This can be very dangerous so be cautious

I have been try a lot of time for use odin to flash cog2 or cod6 from dok2. And it allway fail in odin. And you will receive a notice in the download mode screen like that o"Odin fai, binary =2>1". So you can't flash succesfull in odin.
And evething can't change. I have read 5.1.1 plicy and it also said that we can't downgrade from t mobile phone.lol
Perhaps development can recompile bootloader without tmo security and use Canadian firm to patch.
I just upgrade from COG2 to DOK2. Is there any difference? Which is better?
I have the N910T.
Dok2 has been reported to have improved performance and battery life than cog2 but cannot be downgraded.

I see. My cook ROM say use DOK2. I didnt know about the downgrade. I guess its ok and thanks for the info.
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...
Sent from my SM-N900A using Tapatalk
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 Rooted awhile back and I am searching the forums to find information on how to update my current 5.1.1 to Marshmallow....
Should I simply flash a new rom with ODIN? Or I need a new Kernel? I'm trying to be overly cautious. Where do I find the new Kernel or Rom? I went to the SkyHigh page that I rooted from originally but it looks like he has not updated since 5.1.1.
Any help is appreciated??
Thanks,

Hi, go a head and download a Marshmallow Firmware from here:
Firmware for sm-n920p
use this tool to download faster:
SamFirm - Samsung firmware downloader
flash via odin and then search for a custom kernel. I used SkyHigh kernel for marshmallow but he isn't building kernels anymore and took all of his links down (Not in XDA) so I guess you are out of luck. But there are other custom kernels you can try.
I believe you would have better results if you search in Sprint Section (If I'm not mistaking N920P is the Sprint variant)

Go to ndroid.site , search that in google. there u can find latest skyhigh kernel

Here's the sprint firmware. https://www.androidfilehost.com/?fid=24545065934258585 You'll lose everything so backup any pictures, music, etc.
That'll get you up to date on MM. Then I'd sign into your google/samsung accounts so you can get onto the phone and take the system OTA to the latest. Then used odin to flash TWRP, twrp-3.0.2-0-M-nobleltespr.tar. Don't let it auto reboot. Rather once flashed manually boot into recovery. If you let it reboot automatically the phone will overwrite TWRP with stock. Once you boot in recovery flash SuperSU, BETA-SuperSU-v2.74-2-20160519174328. Then you have stock MM rooted on latest. That's what I'm running along with systemless xposed.
Though there's also the latest MOAR Rom that has a lot of options you can flash in TWRP. http://forum.xda-developers.com/spr...m-moar-pc3-mm-rom-v3-0-making-smoars-t3364338
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.
