Remove MDM on SM-N910F using Lollipop 5.0.1 - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello,
I just upgraded my demo unit of Note 4 (SM-N910F) to Lollipop 5.0.1.
Now I want to hard reset the unit. I get the message: "MDM does not allow factory reset". I have tried using the CF-Auto-Unit without luck.
How can I reset it?
Thx!

A quick search on Google learned me that this is most likely because it is a demo unit and Samsung does not like you resetting a specially prepared unit.

Seems like rooting and installing a custom recovery is the best way to go for you, or you could just ask Samsung very nicely

I think I have to wait for a correct Lollipop version for CF-Auto-Root before I can continue.
And yes I agree, I don't think that Samsung want me to do it.

Flash the TeamWin Project TWRP recovery to the phone. It fixed it for me.

What if we go back to stock recovery does it show again the same message when we factory reset mdm not allow to reset is there any permenent solution.

MDM denies factory reset? Install "RETAIL MODE", uninstall, and try again.

Guys, I'm *WAY LATE* on this, but maybe it'll help someone else. I've got a Galaxy Note 3 SM-N900V that has the "MDM Deny" problem -- it seems to have been a demo unit flashed to 5.0 and then sold. I fixed this problem without rooting by (of all things) installing the "US GALAXY NOTE 3 RETAIL MODE" from the Play Store. [Note: THIS IS THE STORE LOCKDOWN APP.) After installing, I ran it BUT DIDN'T ENTER THE PASSWORD TO ACTIVATE, and then canceled. The service was still running in the pull-down window; I clicked on it to disable and then uninstalled the app.
The upshot of this was: next time I attempted to reset the MDM denial was gone and I was able to reset successfully. If you're trying to get root and can't do a factory reset in order to get there from here, try this.

[Q] Remove Custom & "Lock" logo on boot screen

Hello all,
I have a Samsung Galxy S5 with AT&T model SM-G900A. Any time the phone reboots, on the "Samsung Galaxy S5" boot screen, it says "Custom" and has an "Unlocked Padlock" logo as if the phone were rooted or something. A while back, I was trying to do a basic root to allow use of Titanium Backup using the Towelroot app, which failed because it said my phone was not supported. I'm not sure if this has caused it, or if, as I read elsewhere, it was caused by my once changing from Dalvik to ART. However, I have since switched back to Dalvik, I know its not rooted because SU and other such apps wont work, and I have even Factory Reset the device but I can not get rid of this. I would like to return my phone to its default state. How can I get rid of this "Custom" and Lock Logo? Your help is greatly appreciated! Thanks so much!

It won't hurt anything as long as Knox isn't tripped but you can download the full stock retail ROM and flash it in Odin or Kies 3.
Update: Phone thinks its rooted?

Okay, so here is an update. After performing a factory reset in order to try and fix this issue, I was playing around and opened the "Softcard" app and received the message that it doesn't work on rooted phones. Since the Towelroot app did not work, I don't understand this. I have also been unable to get SuperUser to install binaries, saying the phone is not rooted. Don't know what this means or if it helps, but thought id give an update. Thanks again!
Would you be so kind as to provide me with a link to the retail ROM and instructions on flashing it through Kies 3? THANKS!
I'd have to do a search. .. or you could. ?

Thanks, I found the file (I hope) and downloaded odin, and it is currently flashing. I will let you know if it a) removes the custom lock and b) fixes the softcard app thinking the phone is rooted. Thanks for your help!
It Worked!!!!!

I would like to report that flashing the stock ROM has fixed both the Custom Lock boot screen as well as SoftCard thinking my phone was rooted. Thank you Rapunzl for your help, you are awesome!

Setting up an exhibit smartphone

I bought an exhibit Galaxy S5 SM-900I, it is set up in "Showcase mode" and I don't have the password to change any settings (I could go back to the store to get it).
I want to root it and flash a stock Lollipop ROM, so I don't need to preserve any kind of data (in fact, I'd like to wipe absolutely everything from it).
As it is right now, I can't even make a factory reset as I get a message saying "the mod does not support factory reset", but also I can get in download mode.
Which steps would be best suited to set up the smartphone? Should I just flash a recovery, root and install a ROM as if it were any other Galaxy S5?
Go to recovery and do a factory reset.

Not quite as simple as that........
The 'showcase' or retail mode is put onto display models in phone stores and usually includes some sort of protection that prevents removal by factory resetting (I ran into this issue with a display model laptop)
The only thing that solved my case was formatting the hard drive and re installing the OS. The same process for android is flashing a firmware (and maybe pit file) with Odin......
I personally would take the phone back to the shop you bought it from, and tear them off a strip for not removing it when you bought it......

I went to the shop and had the retail mode removed. When I bought the phone I had been advised to come back at a later moment because it had to be "set up" and the clerk in charge of it was in holiday..

#1: you cannot un-trip knox.
#2: you do not have to un-root the phone either.
Your warranty will still be good, just do a "Factory Data Reset"
which is under the phones settings.
By doing a factory data reset the phone will no longer be rooted
and any apps which you have installed will be wiped out.
A Factory Data Reset will also wipe all your personal info like your
music, pictures, video and passwords as well.
Good luck,
Have a great day!

FRP bypass with firmware PH1

I bought a G935V on ebay with a cracked screen. I replace the screen and powered back on and seemed ok but now I am stuck on FRP screen. The seller sold the phone as is, I just thought that meant broken screen.
Is there anything I can do or am I sol at this point?
Keep trying to unlock it until the phone does a factory reset. Or boot into recovery and do a factory reset.

I have the same situation. I also bought on ebay.
I changed the firmware to 6.01. (October 2016). It did not help.
No method with youtube works for me. And in my country there is no cdma.
Now I'm looking for a solution. The last option is to carry the guys with programmers ...
I tried the firmware from version U but they are not installed

Unless the device was not updated to nougat, this option is a waste of time. not only the device will be a pain in the guts, it will make you doubt of your skills and life

Help me flash stock ROM back please.

It all started when I rooted my phone (Samsung J5 2016 - SM-J510FN), installed TWRP through Odin, did a reset and flashed Extreme UX (9.0). Everything worked so as a noob I decide to turn off USB Debugging and OEM Unlock. I reboot my phone and get the message "Custom Binary blocked by FRP". So I decide to look up how to fix it. Kies didn't work so I go through sammobile and download the Stock ROM. I searched SM-J510FN and filtered for my country (Greece). I downloaded the first ROM I found and flashed it through Odin. I was really excited. Then I unlock my phone. I get dozens of popup messages of "x has stopped working" and the launcher wasn't working properly. I would appreciate any help. Is it a firmware problem? Should I do a hard reset and try installing stock again? Thanks.

Doing factory data reset should clear out those errors
Thanks for your answer. I don't really know how to do a factory reset because I can't access the device's settings.
Anyone that knows how to do a factory reset without accessing the device's settings?
