This will unlock developer options in your settings, you'll find it right at the bottom. Look for demo mode amd turn it off.
This is the only thing i can think of when you mention retail mode

I never able that setting, so is turned off
Then turn it on once,see if usb debugging or oem unlock is turned off.Then turn off developer options
Finally the solution,
1) change the original branded firmware with one no brand
2) unlock developer option
3) turn on debug usb
4) turn off debug usb
5) clean install of fortnite

Help with resetting tab s3 (t825)

Hi Everyone, I purchased a Second Hand T825 S3 tablet from Ebay. The seller sold it for parts as they don't know what the lockscreen PIN is. Currently when I turn on the tablet it asks for the PIN code. I can access the Stock recovery but when i try to factory reset is says "MDM does not allow factory reset", also when I try to go into download mode it says Binary download mode blocked by MDM.
Can anyone help me out to get this working?
Thanks

Difficult to bypass if MDM will not allow anything to flash.
Does it allow stock firmware to be flashed?
You could try putting in the pin over and over. On some devices this will reset the device after many failed attempts, 15 plus maybe more.

Hey, did you figure out a way to get past the MDM lock ?

[Q] What to do when option "oem unlocking" isn't shown

Hi
I mean, of course, developer mode is activated. I think the vendor does actively block this option. Is it possible to set that option in the shell? Thanks everyone for a tip.
Which model of mobile phone are you using now?(●.●)
Hi Jason
Its the Cat S61. I activated Developer Mode but the Switch for OEM unlocking stays invisible.

Unlock OEM option missing in developer options.

I wanted to do a custom rom on my lenovo tab 3 710f . I did a hard reset today. But when I entered the developer options the oem unlock option is unavailable. There is no such option listed.
Please sort it out.

If you enabled the Developer Options and noticed the OEM Unlock there before but can’t find it anymore, it is a possibility that you’ve already enabled OEM Unlock, at which point the feature will most likely disappear from the Developer Options menu.

You might start by telling what model phone you've got ie: 965f,965u ?
