Hi guys,
My company handed out Samsung A6 (FM-A600FN) to all staff as work phones. Some people left and handed back the phones without wiping their data, so the phones are still locked with their passwords. Leavers refused to tell us their password because they use the same password for lots of other things. Now we end up with a number of locked Samsung A6 sitting there, and we have to buy new phones for new starters.
I tried power button + volume up, wipe data, it's still asking for the device password or the previous owner's google account. Is there any way to unlock, wipe or flash these locked phones, without the leavers' password? Obviously I'm more than happy to lose all the data in the device, just want to wipe everything so we can give these phones to new starters instead of buying new ones. Some of these phones are less than 3 months old (people didn't pass probation).
Thank you!
Jay

I've tried this today but it didn't work. When the phone restarted, it's still saying "An unauthorised attempt has been made to reset your device to factory default settings. Connect to a Wi-Fi or mobile network to verify your identity", then asking me to enter password or use the previous google account to log in and verify.
I did choose csc_omc... in Odin, also applied BL, AP, CP, and got to "PASS!" at the end. Then unplugged the phone, boot into recovery --> wipe data/factory reset.
In Download Mode, in the top left corner of the screen, it says "FRP LOCK: ON". Is this causing the problem? Is there any way to switch off the FRP lock?
Thank you!

I have a problem.
When installling TW Roms (latest ones) I get "Enter password to use encrypted device storage" - and no matter what passwords I try - it doesn't go further.
When I clean install other roms, it works.
Any Idea?
Search function doesn't work on this site, maybe there are some others with similar problems, hopefully it is curable!
Hae you ever used encryption or exchange or vpn?

Have you encrypted your phone in the past or perhaps its secondhand?
Try formatting your sdcard + flashing a different kernel using odin and try again..
After trying everything in a similar scenario, I input the wrong password about 15 times on a TW-based ROM - then everything was deleted and it was fine

Nothing kept on saying try again.
I went into recovery (stock recovery) and did factory reset and wipe cache. Still the same screen.

Did you persist enough times? After some point there is a timer that you can't try for a couple of minutes and then a countdown...

after reboot I am still trying. Will update if it gives me anything other then try again.
I do not remember setting up any encryption. Though I did at some point used exchange but deleted that account after a while. So when I updated nothing was on it no passwords.

Yeah no luck. I lost count as to how many time I tried again. It remained the same.
I can only suggest installing the xperia-sized ROM by AminX..... this is the one that let me reset.

SOLVED.
Ok guys just a quick update. I haven't had time and forgot about this thread but here's what I did and I am posting here so that somebody in same situation could benefit. I created a note to self in past and found it.
"In case I ever get that annoying Encryption message.
Do the following:
1) For this method to work you must have access to SDcard or internal memory.
2) If you dont have access, make sure you have Superuser file on any type of Memory (internal or external).
(On the sidenote I will always keep that in internal as well as external card from now on.)
3) Fire up Odin - Install Clockwork Recovery in PDA - Do Not Check reset time.
4) START....
5) Install zip from sdcard... superuser
a) it will fail first time with error code 0.
b) do it again (dont worry about that).
6) Fire up odin again.
7) Rename the MD5 i717 file to TAR. (see NOTE)
8) PDA that ****.
9) START and wait....
10) PASS you're done. Thank PAST ME...!!!! "
NOTE : Now I think this will work for other devices than just I717. You must get a stock rom TAR for your device. Dont get the latest but the one before latest.
After booting is complete and the device no longer asks for passcode. Go into security settings of the device. Then Setup a password lock for your device. Make sure its password lock and is at-least 8 characters. NOTE DOWN THAT PASSWORD
REBOOT.
Device will ask for password to unclock, Enter it and then go to security settings again and disable password unlock it or simply set it to slide.
Make sure you have NOT enabled any device Administrators in security settings. Most commonly people with exchange accounts on phone have that.
After this you can flash the any ROM you intend to flash (On stock rom it will still appear.) and if that encryption screen comes up use the password you setup previously.
Again I cant guarantee this will work for individual devices but yeah It worked for me and my friends device (both i717). Its now a goto method to get rid of it.

After trying this method for a few hours it turns out that I had to downgrade, only after that there was an override on the encryption password requirement. Just in case you don't mind reinstalling evrything.
So I upgraded to Lollipop not too long ago and did a factory reset, and ever since then everything "Samsung Account" related does not work. Trying to add a Samsung account does absolutely nothing. It's like the button just doesn't work! Because of this, I wanted to reset my device again. However, upon clicking the Reset button, a little Samsung Account screen pops up for a split second and disappears, rendering the factory reset button useless. Furthermore, I'd use Kies to factory reset, but when my Note is plugged into the computer (using the cable it came with), it likes to randomly disconnect and reconnect to the computer, so I can't factory reset that way. Does anyone have ANY ideas as to what I can do that doesn't involve voiding my warranty? Thanks!

Your issue with not being able to do a factory reset may have a lot to do with the
"Reactivationg lock" option, you need to uncheck it before doing a factory data reset..
With the re-activation lock is checked I doubt you can do a factory data reset.
Once the phone has been reset, do the following:
Go to http://Sammobile.com and download the official stock N910T 5.0.1 Lollipop firmware for your phone.
Then use ODIN to flash the firmware, flashing the firmware will not void your warranty and your phone will
be in the exact same condition as when you purchased it.
Before you odin flash the firmware be sure to go into your phone's settings>security and make sure that the
"Reactivation lock" is not checked.
Also be sure you do a factory reset by going into settings>Backup and reset and do a "factory data reset"
before you ODIN flash the official firmware.
Good luck!

Thanks for your reply! However, I can't perform a factory reset by going to Settings>Backup and Reset, because the "factory data reset" button does absolutely nothing when I press it (besides launch something that says "Samsung Account" for literally a split second).

Have you UN-CHECKED the Reactivation lock before trying to do a factory data reset?
You need to do that first then reboot.. The reactivation lock is in settings>Security
Then do a factory data reset.
Good luck!

I just used the recovery to eventually reset because even with the reactivation lock unchecked it wasn't working. All is good now, thanks!

Just factory reset in recovery (twrp/phills'cwm) is not the same
same thing as doing the factory data reset in the phone itself.

How so? I thought it was the same, especially since I don't have a custom recovery. Everything seems to be working fine now too.
For some reason my Galaxy S5 mini (SM-G800) Android 4.4.2 is locked and asking for the alternate password instead of my fingerprint. I already restarted it, took of the battery, but it always goes to the same locked screen on boot.
I also tried the Android Device Manager on my google account. I tried the Lock option, changing the password, but since the phone was already locked, it is not working. By the way, the phone WiFi is on.
I searched a lot and found no solution besides resetting my phone and loosing everything or voiding the warranty flashing some recovery room. The are a lot of photos and stuff that I don't want to loose! So the reset is still not an option.
It seams so stupid that I own the google account registered on the phone, I own the fingerprint to login and I know everything is inside the phone, but I cant login! Any simple email account have a forget password option! Why the fingerprint login does not come back!?? Stupid programmers!!
Some sites says that after about 20 incorrect passwords tries it would give me an option to logging using my google account, but I already tried a lot of password and the only thing that happens is a wait 30 seconds countdown ! Where is that google account recovery options? Is it missing on Android 4.4.2?
Is there any way I can backup my data without voiding warranty?
Bro there are no 4.0.4 version for this device. It coming up with 4.4.2 and 5.1.1 versions

Where is the backup option? :crying:
Is your phone rooted if yes do this reset your phone than download diskdigger app from play store n u will b able to restore your data again
No, it is not rooted. :/
Hey guys and gals,
just wanted to bump the OP. Same story here... In short: Only asks for alternate password, not for a print. Non-rooted phone...
I thought about the following (going on my S3 knowledge here... If S5mini is different please correct me):
I could flash twrp via Odin, boot directly into recovery and then (after backup) delete password.key under /data/system/
That would remove a pin/password lock for sure. But does someone know if that would also clear the alternate password to the fingerprint? Or is that stored elsewhere?
I'm pretty sure factory reset and restoring the backup would do jack because the fingerprint data and the alternate password must be stored in there.
Any ideas/knowledge are/is welcome except some mumbo jumbo restore app...
Alright people, who dares wins... I just tried to resolve this issue and it WORKED! :highfive:
Only downside: This will trip KNOX and void your warranty! But most people don't care, and so do I.
So for all who have this or a similar problem, here's what I did:
1) I took this TWRP version, flashed it via ODIN and removed the "auto reboot" option (this is to prevent the UNrooted system to overwrite the recovery again on boot)
2) The phone I had could not be booted to recovery directly from download mode (as can be done with my S3...), so I removed the battery, reinserted it and booted to TWRP via 3-button-combo
3) I renamed the following files via "TWRP->Advanced->File Manager" to make the system "unaware" of them (choose whatever renaming scheme you like):
/data/system/personalfingerprintpassword.key
/data/system/fingerprintpassword.key
4) I then rebooted to system normally and was greeted with the standard "swipe lockscreen". Done!
On a side note: I then went on to change the lockscreen method to PIN. In the settings it still said "fingerprint" as the current locking method. And when I tried to change that to PIN it asked for the fingerprint. So I swiped the finger - which was recognised - and I could ONLY THEN change the actual setting. So the actual fingerprint data must be stored somewhere else...
Hi guys! I've been looking for help in the site all day now and I've decided to ask for more specific help.
I have a Note5 SM-N920l, I bought it online, I believe it's Korean. It's factory unlocked or international, something like that. And was running the Android Nougat 7.
I successfully rooted it and also installed Magisk. It was working great but while trying to get Pokemon Go to work, another story, I tried switching different settings and I turned off the OEM unlock. From what I understand (I am a noob) that has to do with the FRP. I had turned it on to be able to flash stuff onto the phone and I turned it off again and I forgot to turn it on... and I turned off my phone.
I was stuck in the booting screen with the red letters on top that read "Custom binary blocked by FRP lock". I tried booting into my custom recovery but FRP doesn't allow that. I can get into Download mode but when I try to flash things in ODIN the FRP block comes up and doesn't allow anything. (Tried to flash the firmware)
After trying to flash some things I am stuck with a blue screen that says "An error has occurred while updating the device software. Use the emergency recovery function in the Smart Switch PC software." I downloaded said software and it can't find my S/N. So it has not helped me either. I also downloaded Kies but it is stuck in "Connecting".
I don't know what else to do. I don't mind losing all the data and personal files in my phone, I'd like to know if there is a way to factory reset it or wipe it or remove the FRP. I am desperate, this is my only phone and I really need it. I'd appreciate any help I can get.
I have a N960F/DS i bought it in Singapore and it's been fine so far. However, yesterday i wanted to root my phone and try some custom rom. When i click the oem unlock option, it asked me to factory reset the phone. But i cannot click on the "Delete All" button. It's grey out. So i went to the Recovery mode and select wipe data/factory reset it says MDM does not allowed factory reset and the phone reboot..
That is basically what happen.
Here's some extra info. When i first bought the phone, i used it for a few days and it starts to lag a little so I factory reset it before, and everything works fine after that. I did flash some update via odin and firmware from samfirm. So i thought maybe i flashed wrong firmware. I tried to flash the original firmware, bl, csc etc but it doesn't solve my problem either... Any help???
I searched it online and I saw some solution to this : Apprently you had to flash some mdm fix, but it's for S9. I wonder if I could use it for the Note 9
