[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Solarenemy68:
That is part of the KNOX system. Rooting trips it. So Now your phone has been permanently marked in its hardware as tampered. Any system that checks it integrity will now fail it. You will never be able to get OTA updates now. Also if your employer uses KNOX on their servers you will not be able to use this phone to connect to their servers for email now. That is the purpose of KNOX to assure network providers that the phone is stock and not tampered with.

Even if you try to unroot it the KNOX flag will still be tripped. This was an issue on the NOTE 3 as well. Once the KNOX flag is tripped it cannot be reset as it is in the hardware.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] wisnia99:
Thanks for the explanation i really dont care for tripping Knox as long as i can update trough Keis or wait for new roms
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] TheCrzy1:
You can use the Wanam Xposed module to fake your system status and still get System Updates. Thats what I did.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] wisnia99:
So if they do any firmware or radio updates wouldn't it break the root?
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] GalaxyBlaze7438:
I ran into the problem on note 3 if u Odin back to stock u can get updates depending on devs if they have a new root method or not I generally never updated till I found I method to reroot
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Itchiee:
You can still use Odin to flash roms if needed, or the wanam trick....
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] cknicker:
I installed wanam and set my status to official but the OTA system update still fails with the message my phone has been modified. I have galaxy tools installed with native tether enabled if that matters. What should i do to enable the update?

---------- Post added at 01:17 PM ---------- Previous post was at 12:30 PM ----------

The OTA Still errored with a "device has been modified" or some such. I ran triangle away and saw my binary status was 'custom'. I checked the triangle away 'auto reset at boot and that fixed my binary status. Now i well retry the update and rpt back.

With my sprint note 4 wanam doesnt help nor triangle away although binary, flash and counter all look good in T Away
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] jhill110:
Well, if you are rooted and have custom recovery you can't get updates, "ota's" you will have to wait for a dev to come up with a flashable update. Being on 4.4.4 no reason to worry... You are up to date.

Oh, btw, forget about triangle away... It no longer serves any purpose for us...
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Real_JESRadio:
On stock unrooted you still get OTA. Even with Knox tripped. If you have a custom recovery and root dont take the ota if you are promoted. It will brick your phone and you will have to Odin back to stock anyway.

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] jhill110:
Interesting. I came from the S3. Trying to take an ota wouldn't brick the phone but it would stop any future notifications of updates. We were fortunate to have a lot great devs there.

Btw, if you can still Odin the phone is not bricked. Bricked is dead...
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] xxSTARBUCKSxx:
Came from the S3 myself as well. Definitely a lot of active development until after SlimKat 7.0 and then that fell apart just in time for getting the Note 4. The numbers 4 and 3 i am starting to despise.

Slimteam, when i was keeping up with them, stated something about Android 5.0.

Maybe well get a surprise and see SlimPop for the Note 4. Slimpop isnt as euphonious as it looks to the eye...

On Topic: i wasnt able to update after rooting either as the phone is currently already UTD.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Real_JESRadio:
I mean soft bricked. And I should have elaborated, if you have a custom recovery you will soft brick taking an OTA update. Yes, some ROMs eliminate the OTA capability but some stock based ROMs will still get a notification.

---------- Post added at 12:47 AM ---------- Previous post was at 12:45 AM ----------

That is the latest update. A new one is coming soon. But you should be on the latest with that build.

Does anyone know what is in this latest update do I need it if so where can I get it in a flashable format that works with a rooted phone
[Verizon Samsung Galaxy S 4] Verrigan:
Forgive me if this has already been answered... I did a quick search with subject keywords, and didn't find anything..

Will doing a factory reset in phone's recovery remove safestrap? I'm assuming it will not, since safestrap is installed in the system partition, but I just want to make sure..

Also.. Are there any reasons not to do a factory reset in phone's recovery? Using hypderdrive, and having issues with s health crashing.. Did a search that recommended a factory wipe, and want to make sure this is something that's not going to force me to turn on the old computer and start up Odin..

Thanks!
[T-Mobile Galaxy Note 4 General] BotsOne:
Earlier today I was mucking about and decided to play around with the fingerprint scanner for the first time. When I went in to settings and clicked the fingerprint manager, I received an error stating that the scanner is borked, and to reset my device to fix it. Rebooting did not fix the issue.

Soon I found another person with the same issue, who said that he was able to fix it by flashing stock NJ7 via Odin. After a bit of chatter we realized that neither he nor I had set up the fingerprint scanner before flashing a ROM. We basically booted the phone and went straight to rooting it, and flashing ROMs on it.

I can confirm that re-flashing the stock ROM via odin allowed me to set up the scanner successfully, and that the functionality has not been affected by any subsequent ROM flashing.

I do not understand the mechanism behind why this happens, it is just my experience. Perhaps there is some sort of validation that is run the first time you use the scanner, making sure you are running official firmware, and then setting a flag somewhere? How then would that flag be saved for all subsequent rom flashes? Hidden partition or some ****? Hardware flag? I dunno I don't get it, but I figured out how to fix it by golly. Hopefully this helps someone else.

If any others can confirm the same issue, we may want to add this as a step in the rooting/romming how-to threads, so that others don't run into the same issue.

One good thing is that when I flashed stock via odin, it didn't wipe my data. I was able to then flash TWRP and then Dynamic Kat again, keeping all of my settings the whole way through. Ended up not being as much of a hassle as I thought it was going to be :good:
[T-Mobile Galaxy Note 4 General] santos.moreno3:
Thank you for sharing this, I have to say in my case it is not working now i did get the phone rooted and then added jovys rom then did my setup the fingerprint scanner worked for me, then i installed dynamic rom and then the later update of same rom and then the fingerprint scanner is no longer working for me there is a new update for the rom i am going to flash and see if it works now as in a previous version the bloat from samsu g had been removed and with jovys rom being stock rooted it was still there, so i am wondering if it has to do with some of the bloat from Samsung and it being removed that breaks the fingerprint scanner, i will report after i flash the new version of dynamic.
[T-Mobile Galaxy Note 4 General] BotsOne:
I first noticed the problem while I was on Dynamic Kat 1.1 and thought the same thing, that it was something to do with the Sammy apps, but it still didn't work after updating to DK 1.2. I've had it both working and non-working whilst running the same ROM (1.2,) and the only thing different between the two instances was the fact that I configured it while I was in stock in one instance.
[T-Mobile Galaxy Note 4 General] boodies:
This is important information. Hopefully the devs will be able to fix this asap. Thanks!!
[T-Mobile Galaxy Note 4 General] android242:
Wow thank you BotsOne! I'm having the same issue. I'll try this in the morning. Before I rooted, I set up the fingerprint scanner and it worked fine the I switched back to swipe, then rooted. After rooting I installed Jovys rom and lo it hasn't worked since. Does the lock screen have to be set to fingerprint scanner at the time of flashing roms or can you set it up once and move on from that point forward? Thanks again!
[T-Mobile Galaxy Note 4 General] BotsOne:
Honestly I'm not sure. We need a few more people with the same error to get to the bottom of what's going on here. I could be way off with my assumption. We need a bit more info.
[T-Mobile Galaxy Note 4 General] android242:
Cool I'll try tomorrow and report back..
[T-Mobile Galaxy Note 4 General] TEKHD:
Yes, I am quoting the entire op...

Give me some more evidence of this and I will edit the Root & Recovery Guide immediately... I have seen conflicting posts on this matter too... Also, is not clear if private mode does continue to work after rooting or not... Can anyone confirm... (without flashing any roms... from original unrooted to rooted) Private mode... does work or not??? (Private mode is not suppose to work after rooting... but some say it does work???)

Nice post! Come on people... help...
[T-Mobile Galaxy Note 4 General] inphamous36:
Before you back up your rom, disable fingerprint scanner and delete saved fingerprints. If you don't and you go do your backup and ever plan on using the scanner again on that backup, it won't work. One of the guys thinks it has to do with the fingerprints being encrypted so when you restore, it can't decrypt it and locks you out.

I can confirm personally that disabling it before you do your backup then flashing a new rom then restoring your old backup, the fingerprint scanner will still work. Just have to set it up again. But that is a whole lot easier then flashing stock with odin again and starting over.
[T-Mobile Galaxy Note 4 General] BotsOne:
I think this may be an additional problem for flashers, but not necessarily the same one I am addressing. The reason I say this is because I hadn't configured the scanner at all previous to when I discovered that mine didn't work, the error completely prevents me from opening the fingerprint manager. I couldn't even enable the fingerprint function to begin with. Does that make sense?

Not trying to argue just trying to make sure we are on the same page =)
[T-Mobile Galaxy Note 4 General] Z51:
Just noticed my fingerprint scanner isn't working. Wtf lol
[T-Mobile Galaxy Note 4 General] COCODRILO45:
i notice this problem as soon as i flashed first rom the only way o get it working again is flashing back to stock odin but no matter what i do as soon as i flash a rom I get a error message ? here the post another member had the same problem

http://xdaforums.com/note-4-tmobile/help/fingerprint-sensor-error-t2918069
[T-Mobile Galaxy Note 4 General] force70:
Thats not entirely accurate.

I set up my stock rom with the FP scanner...backed up in twrp as usual and i have flashed 4 roms since then and had to set it up gain each time and never had a problem. Ive never disabled it once.

[T-Mobile Galaxy Note 4 General] JawjaBill:
So what exactly must be done to preserve fingerprint scanner functionality before flashing a custom rom?
[T-Mobile Galaxy Note 4 General] inphamous36:
Have you tried restoring a backup and using the scanner? That's when it breaks. I can flash roms fine without having to disable it, but it didn't work after I restored a rom that had it enabled. Locked out of it
[T-Mobile Galaxy Note 4 General] keitht:
I can tell you my history. I setup the fingerprint scanner right away before flashing anything as it is a must have feature for me. Later, I flashed a couple different ROM's and never had an issue. Just had to setup the fingerprint again. So my guess is if you set it up before flashing any ROM, you should be good. At least I was. I haven't had to disable before flashing or anything like that.
[T-Mobile Galaxy Note 4 General] TEKHD:
And... We ALL agree that Private Mode is Not working...? Right... No Private Mode since rooting... Right? There is absolutely nobody with Private Mode still working after rooting...
[T-Mobile Galaxy Note 4 General] keitht:
I think once you root the KNOX counter gets tripped preventing private mode.
[T-Mobile Galaxy Note 4 General] TEKHD:
Yeap I know... but there is this:

http://xdaforums.com/galaxy-s5/development/mod-enable-private-mode-knox-0x1-t2904723

That almost nobody seems to know... It's actually possible to regain Private Mode after a tripped Knox... (Not impossible)
[T-Mobile Galaxy Note 4 General] louforgiveno:
Well now....never tried it but just did and its working for me. Rooted, jovy23 deodexed stock, twrp.

The day i got my phone i odin'd update then installed twrp, then wiped everything but int & ext sdcard, rebooted to recovery, wiped again then flashed the deodexed stock rom.....just tested fingerprint unlock last night for the first time, no problems and just now tested private mode and again that works for me.
[T-Mobile Galaxy Note 4 General] keitht:
Oh cool. I guess someone figured out how to correct it. I don't have a need for it so never tried it.
[T-Mobile Galaxy Note 4 General] TEKHD:
Dang! see...???????????????????????? WT#!!!?
[T-Mobile Galaxy Note 4 General] louforgiveno:
Here in action......
[T-Mobile Galaxy Note 4 General] TEKHD:
This is exactly why I posted comment #8 here... there is actually people that still have Private Mode working after a tripped Knox... I am not crazy... see... lol... So we have to figure out how exactly that happens besides the fingerprint issue... 2 things unknown... Private Mode & Fingerprint...

I will personally debunk this whole issue in the next few minutes... I have a virgin unrooted Note 4... (with N910TUVU1ANJ7 updated via OTA)

-> With the fingerprint scanner already in use (one finger scanned 10 times and saved)

-> With a saved picture inside the Private Mode

I will root it right now and post results...

_____________________________________

Okay, DONE IT!

I think I know where the issue is...

A question for [MENTION=2685386]louforgiveno[/MENTION]...

For [MENTION=2685386]louforgiveno[/MENTION] -> On the SuperSu screen where it ask's you to remove Knox... did you remove Knox or not?

I haven't yet removed Knox and I still have both Fingerprint & Private Mode Working... This might explain why the ones that are using Jovy's rom don't have Private Mode... Because Jovy removed Knox completely.

Edit... Few hours later... still working Fingerprints + Private Mode... (I guess I will never disable Knox with the SuperSu Popup...) I have the best of both worlds... Root with Private Mode + FP

Can anyone confirm that by ignoring the SuperSu Knox Popup... everything keeps perfect... (anyone clicked Disable Knox and still have Private Mode?)
[T-Mobile Galaxy Note 4 General] Diablohtr:
Posted this two other places, but thought it useful here too.

I had FP setup on stock rooted, working great.

Created a TWRP backup.

Wipe.

Flash Hyperdrive.

Go to register FPs, get an error message telling me to reboot which doesn't help.

Restore stock rooted, remove FPs.

Wipe.

Restore Hyperdrive.

Still doesn't work.

Thoughts?

So far the FP is working with every ROM, stock ota rooted, jovy, and dynamic. KNOX is disable on my device .. dunno about private mode never use it. and im currently on dynamic 1.1 great ROM.
[T-Mobile Galaxy Note 4 General] COCODRILO45:
i have the same problem i flashed back to stock odin 4 times works fine but as soon as i flash a rom i get the error i tried a couple ideas the members here have brought up but nothing works for me ?
[T-Mobile Galaxy Note 4 General] Mayonesa:
This kinda worries me. Not that the fp scanner is a must have but it is part of the phone

I had them registered before i rooted. Went ahead and rooted the N4 then flashed firekat to find out it wasn't working.

I did disable knox in su.

I tried going back to my backup where they where working but it asks for a fp but it wont recognize any. I use my backup password to unlock, but the same password wont work when trying to change the lock to swipe.

It has to do with the encryption im guessing. Im going to try to flash the stock full firmware in odin to see if that solves it.

Ill do it over the weekend so im in no rush.

I also have to upgrade from NIH so ill flash the new firmware then as well.

Hope this work

I've always answered yes to disable knox in the past .....i can't remember physically doing it as i was rooting my wife's old phone to backup and merge her to my N3 so it all blurs together. I have wanam installed with disable secure storage checked....has everyone tried that.
[T-Mobile Galaxy Note 4 General] santos.moreno3:
So I went ahead and updated dynamic hoping that would of fixed the problem before I read it didn't work for others then I used a backup I had with jovys rom I had the scanner running then when I backed it up as it had been working but after installing the backup it didn't work as someone else indicated they had the same luck, I did notice my baseband is not NIH Not NJ7 I Wonder If This Has Something To Do With It, How Would I Go About Updating It To NJ7 Or Doing A Complete UNROOT And Reset I Hit Factory Reset But I Am Still Rooted Tried Full UNROOT On Superuser And It Just Hangs There Thanks In Advanced
[T-Mobile Galaxy Note 4 General] fbueller:
Came out of the box, registered fingerprints, installed TWRP, wiped all data, caches, etc. and then installed stock rooted NJ7 knox/carrieriq free. Fingerprints don't work. F'ing hell.

Update: Restored to stock, checked and was now able to open fingerprints but just hit back after hitting the option, DID NOT REGISTER ANY. Then installed TWRP. Rebooted. Fingerprints worked again, but I didn't register any. Then updated to Stock Rooted CIQ/Knox Free NJ7. Fingerprints work.

same here, when i was stock i used the fingerprint scanner.. i never removed my stored finger prints.. rooted flashed recovery and built my rom.. no matter how many times i flash test builds i never have an issue .. odd some r :eek:

Ditto here, looks like the key may been we set up fully prior to any mods and have never removed our fingerprints.

[T-Mobile Galaxy Note 4 General] BotsOne:
Almost seems as though you only need to open the fingerprint manager while running stock in order to use it in the future. Anyone's experience contradict that statement?
[T-Mobile Galaxy Note 4 General] fbueller:
My first run through I registered fingers on stock and then updated to TWRP and Knox Free/CIQ free stock, and it didn't work. So my initial experience contradicts that if you're including registration. If you mean opening the app but no registration, then maybe.
[T-Mobile Galaxy Note 4 General] BotsOne:
I was referring to solely opening the app, not setting anything up. I wonder if someone were to post a logcat while opening the app on a brand new stock install, if it could provide any clues as to what the hell is going on here.
[T-Mobile Galaxy Note 4 General] louforgiveno:
yup....my experience

I tweaked my phone fully before Ever trying/opening fingerprint & private mode

Again......When I Wipe in recovery,

I wipe full THEN reboot BACK to recovery, Wipe and THEN flash new rom......

I suspect that some of the times people hold on to and restore as much system data as they can and don't really wipe it down.....btw flashing stock odin file is not the same as wiping.

UNTIL you wipe it down, errors and problems may follow.
[T-Mobile Galaxy Note 4 General] Diablohtr:
Everyone having problems,

Make sure you are matching the modem baseband to your ROM. NJ7 to NJ7 etc.

Flashing the right modem fixed it for me!
[T-Mobile Galaxy Note 4 General] santos.moreno3:
This fixed it for me as well I was running nih baseband with nj7 roms flashed to nj7 baseband now fingerprint scanner is working
[T-Mobile Galaxy Note 4 General] Mavman42:
I set my fingerprint scanner when I was on stock, when I flashed Dynamic Rom fingerprint scanner still works perfectly.:good:
[T-Mobile Galaxy Note 4 General] fbueller:
Interesting - I did notice that on my initial update to the rooted rom my baseband mismatched. My second run through they're both on NJ7. So maybe this is the fix - make sure your baseband and rom versions are in sync.
[T-Mobile Galaxy Note 4 General] kg6bki:
I can confirm this...I was on Hyper Rom. My Baseband was different from the NJ7...it was on the old baseband...Once I flashed the NJ7 Modem in ODIN...Problem Solved...FINGERPRINT NOW WORKS AGAIN:D
