Can't add fingerprints - "Fingerprint setup was cancelled"

After restoring a twrp data backup, I cannot add new fingerprints in settings. It just repeatedly says "fingerprint setup was canceled" on the menu where you actually press your finger down repeatedly. I can click try again but it still says canceled. I RUU'd and the fingerprint setup does work in the first-run setup wizard. I restored a new backup from the faulty phone on the new phone and again cannot add the fingerprints.
Using 3.0.2-7-test3 version of twrp. backup of my 2.28.617.8 data and boot on a phone sent from RMA due to the last one not having GPS functionality. I have both phones still (about to send the "old" one back to RMA). Backup has patched boot and root for magisk. Adding fingerprints works on the rooted phone I'm backing up. I also tried deleting the 3 locksettings.* files from data/system to no avail. The new phone is perfectly functional, so far as I can tell, except I can't add fingerprints. The home button works for waking up screen when no security is enabled as well as long pressing for google now.
Any ideas what could be bugging out the add fingerprints dialog?

Did you ever find a solution as I am having exactly the same issue...

Rom update utility (RUU) did the trick in the end.

Thanks - I ended up doing a complete wipe and re-install of the LeeDroid ROM I am currently using and haven't had any problems since...

Any way to backup finger prints?

Title says it all, I constantly switch ROM's and would love to be able to just backup my finger prints and restore them whenever I install a fresh ROM without re-setting all 4 finger prints each install

Don't think so.. Could give alot of issues also. Is it really needed for that extra 30s you spend?

Can't. Even a full nandroid backup messes up fingerprint data.
That thing is secure for a reason. If you could simply back up fingerprints and restore them, you'd have a huge security hole.
Example: backup fingerprint on your device, get hold of someone else's device, restore your fingerprint to it.
Kinda pointless then, isn't it?

The files that matter are locscreen.db but the problem is if you copy that file later when you try to unlock the new rom won't accept even the correct password so as rom changes it messes up the pattern and pin hence there is no way currently

Rooted N4 issue after reset

So I gave my mother my note 4 rooted Ultimate Note7 Hybrid SM-N930P and I wiped everything before I gave it to her. But when setting up her phone it asks for pin number for screen lock so I make one. Then when trying to unlock it it won't allow it. It looks to go to the next screen but flashes then goes back to lock screen.
Any help would be appreciated.
Thank you

Maybe a little late to reply but what did you wipe?
Recommended way to turn phone over to another user is to remove fingerprint(s) and accounts while booted. And make sure the reactivation lock isn't enabled.
You can factory reset after the above.
Maybe you can still factory reset but if that doesn't work, I don't know why it wouldn't unless reactivation lock is enabled.
Did you try the factory reset? Did that work or no?
Edit: if it's just a persistent fingerprint issue, try this but read the whole thread.

Flash this zip file from twrp or any custom recovery and it will bypass any lockscreen security lock. pin/pattern/password/fingerprint.

I wiped it from recovery mode with the TWRP
It isn't a finger print issue. It's the 4-12 digit pin number

Trying to help so I won't debate the issue. It's important to recall if you went back through setup wizard and were prompted for original user and account password.
I still don't know what partitions you wiped. You likely need to root again if you wiped data or factory reset. I thought a factory reset would remove fingerprints.
The reason I think it's a fingerprint issue is the prompt for pin after reboot. I think that still applies since it asks for one and won't unlock. On initial prompt after you wiped it, did you input your personal backup pin to unlock and set another pin? Original pin should be wiped but if not your accounts and likely prints still exist.
I may be wrong but you may have to restore a stock backup or go back to stock tar in Odin if the two suggestions given aren't helping. I'd suggest the same stock tar as before in case it is factory reset protection causing the issue. You may have use your original Google or Samsung account user and password to unlock it.
But before following through with Odin, one important thing to look for in phone's display is reactivation lock while phone is booted to download mode (for Odin). If enabled, factory reset protection is applied. I wouldn't flash but pull battery and factory reset and sign in with original user and password. The prompts should direct just that. After setup wizard, remove anything of yours like fingerprints and accounts and factory reset within system Settings app.
As I said in my initial reply, you need to remove your accounts and check for fingerprints and remove those if applicable. Then factory reset. I didn't mention it before but factory reset in system Settings app is recommended to avoid issues handing phone to another user. Not sure but it may be a more sanity check to ensure you've removed accounts and fingerprints and encrypted data. I forgot to mention encrypted earlier.

TWRP backups, move to new phone

So my old 5x died with the BLOD - I managed to get into recovery using TWRP build for 4 cores and grab a full backup. This was running 8.1 Developer Preview.
I have a new 5x now, obviously I want to move from the developer preview to the latest build, which I've flashed fine.
Can I simply restore the "data" partition from my old TWRP backup to the new phone via TWRP or would this cause untold problems!?
I have tried just restoring everything, but the phone just hung for 4 hours doing nothing when I tried this.

Yes, just restore the data partition. The only problem you might run into is if your other 5x had security on it, pin,etc, you may have to re-flash the firmware and then not use your old data partition (even if you know the old pin, etc, ). I ran into that on another device. I haven't tried on my 5x though. To get around that issue I had to remove any security before making the backup.
Oh, also, absolutely not try to restore the efs partition from your old device. You'll never be able to use the phone if you do.

Cool - I'll give it a go and see what happens. After taking the backup from the old phone I disassembled it and tried to do a solder reflow - it's a dead brick now
So if this doesn't work I guess it's a manual task - which isn't the end of the world - just very annoying.

Sooo close to working - data partition went in fine, everything looked great - 2000 messages and notification popped up as it caught back up... but I can't get into it as the "PIN" code is wrong.
Was the same PIN I used on both phones but it's not working, and the fingerprint won't unlock it either!
Ah well.

Do a more thorough search of this forum. You can bypass the pin by deleting a certain file. Your question about requiring a pin after restoring a backup pops up once in a while and i think here is an older dedicated thread.

That's the same problem I had. Good to know it's the same on the 5x. Next time set security to none before you make the twrp backup. I know to do the same now.

I think you're referring to the files in /data/system related to lock settings. You can delete them from twrp but, at least in my case, twrp required a pin to get into it.

File to wipe Android-PIN: /data/system/locksettings.db
File to clear TWRP-settings: /sdcard/TWRP/.twrps

Cool - thanks all.
Managed to use TWRP to delete old PIN stuff, all the fingerprint stuff which also didn't work and had to reset all my networking.
But appears it's all back together and working and just like my phone hasn't died.
Appreciate the pointers.

Stuck at lock screen after failing an update

Recently, phone updated itself automatically to 11.0.3 version from 11.0.1. Now it is stuck at lock screen and none of the gestures or buttons working in lock screen(only long pressing power button restarts phone). Phone is china version. I can access to the fastboot and recovery. Can I fix it without installing new rom on it?

Deleting the lockscreen password seems to fix it for me, had this happen a few times. You can do it through twrp, delete locksetting* or gesture* from /data/system.
If you can't mount data, then formatting data is the only way, wiping isn't the same.

You can try flashing back to your previous ROM but I think your only options are going through TWRP to save your data or formatting data.
Maybe someone else can chime in
