USB Debug option greyed out - Samsung Galaxy Note 20 Ultra Questions & Answers

Friend got Google locked out of their Note20 Ultra. Has anyone ever experienced an issue with being unable to enable USB Debugging due to the feature being greyed out? He would like to be able to use his phone again so we're hoping someone here knows why and how it can be either fixed to be able to enable it or a work around to get past this.
Thanks in advance!

Autostarts freezes even with USB Debugging Enabled

I am trying to use autostarts, which is an application that disables things from running automatically. I have seen people say that the app freezes when trying to disable something, and to enable USB debugging. I have it enabled and it still freezes when I try to disable something. Anyone else have this issue or know a way to get it to work? Thx
I had the same issue a couple days ago. I have a Samsung Epic but hopefully this will help you to.
I had the same problem when I didn't have USB Debugging checked in the settings menu. So I read the forums and found out that is what I had wrong but that didnt work either.
So I got it to work by making sure USB Debugging and Stay Awake was on. Rebooted the Device and had it on the charger while I did it and Autostarts started to work like normal.
Hopefully this was somewhat helpful and it works for you

Issues accessing usb diagnostic mode in Lollipop/cm12/pa

Ok, after searching quite a bit, there doesn't seem to be any way of configuring usb diagnostic mode (sys.usb.config diag,adb) in CM12/PA 5.0.2. I've tried several times, and the closest I get is adb working and the diag port either constantly turns on and off, or doesn't read at all. I'm thinking it might be due to the fact that I can't seem to fully shut off mtp in storage. It only turns off (meaning the screen to switch doesn't open) after I issue the diag,adb command. I'm not sure, but I'm leaning towards this being some sort of new setting for Lollipop, which, if so, I guess I can try writing a script that might allow diag access. But, if anyone has any insight into this, please let me know. Thanks for reading.

Shameless bump is shameless. For shame...
Hello, did you find something out?
I'm looking for a solution too. I think we are screwed until there is an OS update that fixes it

hi guys...
any news from diag mode for CM12..?

Unlock method option disappeared from settings

I know it might because of the KNOX and I know it will disable some options like USB debug due to some sort of "security policy". But I uninstalled it one day ago, rebooted this phone 3 times, now the USB debug is working but unlock method option still not appear in the settings. Does anybody know how to get this thing out? Any help will be appreciated

cant unlock huawei mate 9 mha-al00 chinese phone.

I cant figure out how to unlock my Huawei Mate 9 model MHA-AL00 Chinese phone. The ABD tools don't seem to work. There is no enable OEM unlock option in the developer options. I have the unlock code. Can anyone help me? I really want to root it.
I had the same problem....
I had the same problem with my MHA-AL00. It just wouldn't accept the code no matter what I did. I did a lot research and finally found the solution. Surprisingly simple once you know it. I mean....it literally only takes 2 secs to fix.
Unfortunately, I won't be telling you how to fix it, because of your stupid remark. Have a nice day.
Did you enable USB debugging in developer options? You might have to toggle it a few times until you get the approve dialog on your phone. Make sure USB is plugged in.
As far as I know you only need that for AL00, there is no OEM unlock toggle.
Crap, he is serious ???

I tried all that to no avail. However finally I found the solution... for some reason it cannot work if you have this "Find my phone" enabled. Once I disabled that and restarted my phone it worked. It is know to cause this problem.
@kubinski Please check your PM's

can someone help? can't switch usb port settings to manufacture mode, it says "not support in this state".

I need to connect to hcu client, and to do it I need to enable manufacture mode for USB settings. I tried to do that but it did not work, reporting "Not support at this state!". If I close the window, the changes do not save. What state? - I didn't get it, if someone can explain to me what am I doing wrong and if someone can help me with finding the code, I'll be glad with any help I get.
Thanks for reading, hope you can help!
