Any Way to "Sideload" Fingerprint Profiles? - Samsung Galaxy S7 Questions and Answers

I did a factory reset on my S7 today to fix some strange notification reminder errors, and found out that my home button no longer likes to let me register my fingerprints. The button was working fine to unlock the device today before the factory reset, and I've already attempted the clear cache partition method to get it working again. Any time I attempt to register my fingerprints, it simply says "Make sure that the Home key is clean and dry, then try again." I assume this is due to the fact that the home button got scratched a couple of months ago, but again, it was working just fine with the scratch up until I lost my fingerprint profile.
So, is there any way (including if I have to root it) to "sideload" a fingerprint profile or suppress the "Make sure that the Home key is clean and dry" message when setting up fingerprints?
Thanks

Fingerprints are stored securely by the TEE, so there is no way to sideload, not on official firmware at least. The message you see about wiping the button is also hardware initiated. It should display in any situation where a scan is done, not just when registering. So something happened to the physical scanner at some point. I'd recommend just sending it in if you dont manage to fix it yourself.

Samsung pay fingerprint won't turn on

So my wife decided to add another finger on my device to unlock it which messed up samsung pay. It said I needed to verify for security reasons to use it. I ended up deleting the print but now the pay app won't turn on the use fingerprint slider. I have deleted all the fingerprints and turned off the unlock with fingerprint. Then went in the app and went through the process of adding my print. Still not turned on. Not sure what to do from here.

Hm, this is an interesting dilemma. Try going to settings, applications, application manager, swipe to the left until you're in the "All" tab, look for Samsung Pay, delete the cache and the data for the app, the uninstall the app. Power down the phone completely. Once it's off, press and hold the volume up key, power, and home until you see the little android logo and "installing system update". Use volume up and down to scroll to "wipe cache partition" then press the power button to select it. Once it's done, use the power button to select reboot system. The system may take a bit longer to reboot now but that's okay. Once it's rebooted, re-install and log into Samsung Pay. It should work. Let me know how it goes!
OK thanks for the reply. I'll try when I get home from work and post back

Fingerprint and backup lockscreen are taking time to unlock

I am facing difficulty on my PK1 deodexed rom while trying to unlock the screen. After swiping my finger, ut won't unlock and won't give any reason, just stuck. When i try using the backup password, keyboard won't come up for me to type my password until i lock/unlock with power button and change my keyboard back and forth multiple times before working.
I have checked for possible solution online, cleared cache and wiped data on both app manager and Titanium backup app.
Please any information will be gladly appreciated.
Thanks
Solved!!!
I was able to solve it after troubleshootibg by myself.
Found out its peel remote notification causing it. On the lock screen, the remote icon is always visible and accessible. I turned off its notification and viola, fingerprint and password now working as they should.

Disney Killed My S8+

It was hot. I don't think the phone was necessarily feeling the heat like me... but... the way it was acting... maybe so?
The second to last day of my vacation at Walt Disney World (first time!), my S8+ started acting wonky. I tried to take pictures and the application wouldn't work right.
So, I rebooted.
Now, I'm staring at a screen with a textbox at the bottom of the screen and some text near it (I don't recall it verbatim) "Enter your emergency password".
What? What's an emergency password? Typing in the textbox, it was obvious that it wasn't a numeric-only textbox (for PINs) but it was alpha-numeric. I simply don't recall registering anything but a pin and my fingerprints.
Freaking out, I kept trying to restart and worked with the power and volume buttons.
All I continued to see was the Samsung logo.
Suddenly, I got a black screen with text telling me things were being erased. I then see a blue screen with an android bot telling me stuff was being erased.
After a bit, I was back at the language selection.
Gone. Pictures. Data. SSD... entire phone... fully erased. (Thankfully, a majority of my pictures were immediately put into Instagram... the lost pictures I used the phone's camera app because it works better than the Instagram camera).
Don't have my laptop... so I don't have my password database, so I cannot get into ANY applications.
I know there are requirements for Microsoft Exchange, and other applications that require special security for being a device administrator... I'm not aware of Exchange requiring a password for the phone but... who knows? I didn't enter the password wrong too many times.... even as hot as it was I still used my print to unlock the phone.
Man, that is horrible. My condolences. If you can boot the phone into recovery mode (Hold down volume up, then the Bixby button & then the power button...all at once). Once in recovery, do a factory reset and you shouldn't have to enter that 'Emergency Password'. Unfortunately, everything is lost unless you ran a backup into the cloud or on your 'puter.
Sorry for the post if you've already reset the phone as it sounds like you might have since you mentioned the language screen.

Yeah I didn't have the choice -- the phone decided to reset to a fresh install point. Once I got back home I restored to a previous backup after trying everything I could to undelete stuff on my SDCARD.... but none of the software I tried would work... kudos Samsung... your deletion of my SDCARD was VERY complete...
Did you have the SDCard stand alone or merged with the internal storage? I'm surprised that got wiped also.

The only reason I see for this to happen is if on the "lock Screen and Security", inside the "Secure Lock Settings" have enabled the "Auto factory reset".
Biometrics won't trigger a device wipe, they will only force the pin/password field on too many attempts.
You say Exchange. Is this a corporate account? Is there a possibility that someone remotely wiped your device? Log into OWA (the web interface of your Exchange), navigate to Options -> See All Options, then click the Phone tab and see if a wipe was sent to it. Because what you described sounds a lot like a remote wipe. (Though I've never seen the emergency password field.)
Also make sure that you're not violating your corporate policies. Granting admin access to the Exchange app gives your company full control over your device. They can see you accessing your email with it, and if you're doing something that you shouldn't be, they will wipe your device.

No way of knowing but I don't recall ever setting that (I wouldn't).
something corrupted your ROM it sounds like, somehow!
if it was the red box that says like "enter password" I believe it is actually "default_password"

Fingerprint Hardware Not Available

So for the past few days, whenever I try to unlock my Z5 I get a message telling me that "Fingerprint hardware not available". I've tried rebooting as well as turning off the phone for a few hours with no improvement.
The only way the phone allows me to unlock using my fingerprint is if I press the power button and keep my phone on the sensor. If it reads successfully then it unlocks, but if it doesn't, it gives me the unavailable message.
Even if I get the error and it doesn't unlock, I can still log into apps (like my banking app) with my fingerprint.
Any help would be greatly appreciated.
Cheers,

Bump?
Hello,
I think any data that might have something to do with the fingerprint software got corrupted.
I had this problem as well and I tried to mess with the files in the system. But no joy, it was only waste of time.
The only way out for me was, was to do a clean install.
I mean reflashing the ftf file with clear data.
Issue solved - Fingerprint hardware not available
Guys,
I use Xperia XZ, has the same problem of getting a message "Fingerprint hardware not available" whenever I press the power button.
I went to the fingerprint manager under settings, removed all the existing registered finger prints (my index and thumb prints) and added new. And it worked!

Android Phone locks immediately after entering correct pattern

Samsung Note 10, SM-970F
Magisk Rooted
Android 10, N970FXXS6DTK8
It's my GF's, and she uses a pattern unlock along with fingerprint. No new apps were installed or settings changed that she recalls.
Began as phone locking immediately after correct pattern was entered, but using fingerprint would unlock correctly.
With this immediate locking, the phone will by itself turn off the screen then turn it back on for two seconds as though the power button was pressed, then turns the screen off again.
When entering incorrect pattern, it says incorrect pattern and does nothing else.
She tried restarting the phone, which disabled the fingerprint unlock feature until the phone is successfully unlocked once.
Phone still locks immediately after entering correct pattern, and now she can't unlock it using fingerprint.
Now unable to unlock phone.
EDIT: If I repeatedly enter the correct pattern, after a random number of tries it will go to the 'starting phone' screen, but then will either restart by itself or sit there until I restart the phone. It really is random, once it took 7 tries, another time 20 tries. The phone doesn't show up on my windows PC as a mounted device during any of this.
USB debugging was not enabled, so I don't believe I can run any ADB commands. She didn't backup her phone and our focus is at least to get the photos off the camera, at which point doing a factory reset would be acceptable.
I've tried:
Entering a lot of bad patterns, trying to get to an option of unlocking with the google account associated with the phone, but the option never comes up.
Removing the phone case, only external item on the phone now is the stock screen protector.
Starting into recovery, clearing cache, repairing apps.
Starting into safe mode.
Booting in and out of root.
Letting the battery discharge completely to do a hard power cycle.
But no luck. The phone still locks immediately after entering the correct pattern. I haven't tried taking the phone's stock screen protector off, but will probably do that in case there is something wrong with the proximity sensor.
This is the international two SIM version of the Note 10, the only Note 10 variant which was rootable. I haven't worked on the phone for at least a year since it was rooted and setup.
SEU or a hardware failure. Either way when this happens your only option is to backdoor in. If it was a SEU after resetting you're good to go. If hardware it will likely reoccur... Even with a hardware failure many times nothing happens if no lock is set, you still have access. Setting a lock password introduces added failure modes.
SEU's are very rare but they do happen, randomly and just one bit of data is flipped. Interesting they cause no hardware damage. Higher altitudes elevate the risk as does exposure to man made high energy particles. That's one reason why spacecraft have 3 or more redundant computers. Apollo fights have logged half dozen or more SEU's per flight.
I never screen lock my N10+'s, double tap on/off. This is one reason why. Same with PC bios, no password is ever set. Once bitten, twice shy as the user is always the most likely person to get locked out... as I learned the hard way
@blackhawk, I hear you on getting burned with device security. And for any electronic device, secured or not, backups and redundancy are the only reliable difference between your device being useful and useless. It's been hard not to say any 'I told you so' about this, since I was telling her both to use a pin instead of pattern and to let me setup a regular backup. I don't know that a pin would have been different, but I think it would have since the fingerprint was working before the restart.
Do you have any resources you could point me to on how to backdoor into an android with a password/encryption? I know you can unlock a device using ADB, but I believe you need USB debugging enabled first and I don't know how to make that happen without first unlocking the phone.

Samsung repair can do it. A local shop or yourself, maybe. If there's an associated Samsung or Google account, start there. I never had to do that but the information isn't hard to find. The data will likely be lost though.
Meh, it's a very rude surprise.
