Ive recently acquired second hand galaxy tab s2. It turned out it was used in store before that (previous owner didn't tell me). So after factory reset & wiping cache (using volume and power buttons) it throws a message after boot:
An unauthorized attempt has been made to reset your device to factory default settings. Connect to a Wi-Fi or mobile network to verify your identity.
further it starts enrolling to store :
This tablet will be enrolled with:
......
and only back & next option
downloading MDM
Knox mobile enrollment
To complete enterprise setup process, this device will be restarted and reset to factory default settings. Tap RESTART NOW to continue
I can't also press HOME & menu buttons, as receiving : Security policy prevents use of Home key
Luckily at some point you can go out to main screen and there's notification :
Hub configuration in progress.´
for this app :
play.google.com/store/apps/details?id=com.airwatch.androidagent
I can go to options, enable developer options, and disable above mentioned hub, so tablet stays fully functional
The question is - will installation of clean firmware (from eg. sammobile) get rid of this, or I'm doomed to use adb all the time it gets unlocked ?
I have found wourkaround for similar issues on youtube, but only to bypass this FRP, but they are not clear if needs to be repeated every factory reset..
Hello ,
I think this tablet is under Knox Enterprise . Only the owner registred (enterprise) may modify or desactivate the Knox count .

I think that this problem has already been discussed before, but I could not find an answer. My skill level is too low...
My TAB is a Hong Kong Retail version, which is unlocked.
After successfully rooting my TAB using Z4root, I installed BootStrap for EURO TAB and then I could successfully install Paul’s Modaco R1 version. I did not experience any problems. Then I installed Richard Trip’s Kernel, and I am not sure if something went wrong (or was already wrong), but somehow I could not get access to the Market anymore.
So I decided to reinstall Paul’s ROM using ODIN, but somehow after a successful start, there was a red FAIL. I guess i probably used the wrong setting and fell into the protected boot trap? I tried to get into the boot mode again, but could not get in.
After many tries to get into the boot mode, I now have:
If connected to an adapter: there will be a phone+triangle+PC error message. Sometimes this message will stay on as long as the TAB is connected to the power adapter.
Sometime the phone+triangle+PC error message will get flash slowly.
I tried to leave it overnight and then charge it and get into Boot mode, but no success.
If I try to attach the TAB to a PC or Notebook, nothing will happen. Nothing will happen even after several hours.
So … what is the best way to solve this problem? Please help.

I did a hard reset and it worked...
Samsung Galaxy Tab: Steps For Hard Reset
by Mitch under Android, Hardware
A hard reset will reset the Samsung Galaxy Tab back to factory default settings. You would perform these steps if you want the device prepared to sell or return to the store, but you may also want to perform a hard reset if there are problems with the device that you can’t seem to solve using any other method.
Note: These steps clear data from the device. SD card data like your photos and music are not erased unless you choose to format the SD card.
1. With the device off, press and hold Volume Up and Power.
2. Release the Power button when you see the Samsung logo, but continue to hold Volume Up until the recovery screen appears.
3. Use the Volume buttons to navigate the menu and select wipe data / factory reset. Press Home to choose the selection.
4. Press Volume Up continue.
The Galaxy Tab should then go through the hard reset process.
If you have access to the OS, you can also perform a hard reset in Settings.
1. Open the Settings app.
2. Select Privacy.
3. Choose Factory data reset.
Hard reset probably won't work as it sounds like a bad flash... Any OS you flash will replace your stock OS which is why people say to backup EVERYTHING...
Right. A hard reset (if it works) removes user installed apps and their data. It won't restore anything, but it should return any user-made settings to the default.
Hi, I assigned a pattern lock and I wanted to make a more complicated one.. and well, I simply forgot the stepps to it. So now, I can't unlock the phone, I kept trying all ways possible, after 5 failed attempts it tells me to wait 30 secconds. So I kept trying but I'm not getting a sign in with google promt, it just tells me to wait 30 more secconds. I tried pressing the soft reset button next to the sim tray and that didn't help.
Everything I found on google says that after 5 wrong attempts I'll be asked for my google id, but I'm not getting such a promt. I even went to Android device manager and tried to put a lock password to it but it says it already has one.
I'm on Lollipop by the way, 5.0.1
How do I get into recovery mode to factory reset it, I'm having trouble finding that too.
have you tried repairing the phone with the pc companion?
[pc companion => support zone => phone software update => repair my phone]
Doesn't Device Manager let you factory erase the phone?
Hey everyone,
So I've searched far and wide for a solution but can't seem to find one, anyways my problem is, I bought a tablet(Samsung Galaxy Tab S2 SM-T819Y) off my friend(he didn't know the security pin but he sold it to me for $50 so I thought why not) so now I'm trying to factory reset it so I can use it.
I've let the battery drain overnight(couldn't turn it off before due to the needing the security pin) managed to get into recovery mode once it was off & I charged it a little so I could boot into recovery mode, once booted into recovery mode I continue to select wipe data/factory reset & get this error "MDM does not allow factory reset"
I've attempted to root the device with no success, every solution I've looked at requires me to access into the actual phone & go into settings to change USB debugging, OEM unlock etc. but obviously I can't do that because I can't get passed the security PIN so please if anyone could help me out it would be much appreciated.
Peace out ladies & gents.
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!

Pixel 5 here
So I updated to the beta and the pixel launcher kept crashing (couldn't even swipe or open app without the screen turning black and pixel launcher crashing) after the install until my phone kept restarting and said I needed a factory reset.
I factory reset the phone but when I go to set up the phone again after entering my wifi info the next screen asks me to "Copy apps & data"
if I hit next it asks me to connect my old phone, which I don't have an old phone. When I select "Can't use my old phone" a message pops up saying that I can restore data without my old phone by signing in with my account. I hit ok and it asks me to verify my pin? I factory reset the phone, why would it ask for that?? ANyway I enter my pin and and I'm back to the Copy apps & data screen.
Only other option is "Don't Copy". If I hit that It puts me in an infinite loop of verifying my pin, then back to the Copy apps & data screen.
Any help would be much appreciate, totally lost. Knew I should've not installed the beta :'(
Exact same problem on my 4a 5g, I cant even unlock my bootloader now.
