Cant enable "OEM Unlocking" on Android P preview 1 - Google Pixel Questions & Answers

I flashed the Android P preview 1 yesterday, locked bootloader and I was a happy man.
Today I thought I'll get back to Oreo and now I cant enable "OEM Unlocking" inside Developer Options. The toggle button is always show disabled. When I enable it, it asks for my screen unlock pattern, I give it that and when it comes back to the settings screen, the toggle is set to disabled again.
Any ideas? I really don't wish to be stuck in this version of Android till I buy a new phone
EDIT: I fixed it. I just did a factory reset and I was able to enable OEM Unlocking when I hadn't setup a pattern screen unlock.

I see you fixed it, but I would never recommend keeping your bootloader locked. Just keep it unlocked in case an issue with software happens it is easily fixable

Power Menu

SM-G930V Verizon model. Is there an option hidden somewhere which you can select weather to shutdown device from locked screen or not? There is such option in AOSP ROM I have on my other device, but I was never unrooted long enough to find these options in stock ROM and now am not sure if it is an AOSP only option.
My concern is that if the phone is lost, anyone who finds it could factory reset it before I get the chance to search for it. But I have a chance to find it if it can't be turned off/rebooted when the screen is locked.
I don't believe there is such an option. But while someone who finds your phone can shut it off, they can't easily do a factory reset.

The phone is encrypted. Settings > Lock screen and security > Secure startup, use a PIN. I believe this will prevent button combination on boot. Haven't tried.

Issue with swipe unlock and face rec + pin set it up

hello all,
maybe it is me, I am quite sure I am missing something so I need your help.
I have face rec and pin both set it up. when I attemp to unlock the phone with just a swipe I can unlock it.
tried to let other people do it with same result, just swipe and phone is unlocked.
to be more clear, face rec is working, pin is working too, but with just a swipe phone can be unlocked.
what I am missing? I want to have face rec or at least pin secure to keep phone locked from others
thanks and regards
Check the Secure Lock settings for "Lock automatically" and "Lock instantly with power key".

Just checked mine and it was doing exactly the same until I realised I had smart unlock ( location based) on. I switched it off then everything worked fine.
Check to see if you have smart unlock enabled in settings.

USB Debugging mode

Hello guys.
I'm having a bit of a trouble trying to freeze apps on my PRA-LX3.
I installed Service Disabler from the Play Store but it doesn't work at all. Then I went for Titanium Backup Pro, which always gets me out of trouble. However, even when it says "XXX has been freezed...", it doesn't. No app frozen.
I did some research, and found out USB debugging should be enabled, which I thought I had done. But when I go in developer settings, "USB debugging" is always disabled. I turn it on, go back to TBP, get back to developer settings and "USB debugging" is back off. Even if I just hit the recents button and hit it again to go back to the developer settings screen, it turns back off automatically. I don't know what to do, I really want to disable HiVoice and a few other Huawei crap.
I'd be really thankful if you might help me out here.
activate allow unlocking bootloader.
then "always allow adb in charge mode"
Unlocking bootloader is activated. (Actually, greyed out). I did the whole unlocking process and it worked successfully.
It's the USB debugging which doesn't work.

I tried to use Action Launcer on my One Vision, it started doing EXACTLY that (restart after unlock).
The only way I could solve it was entering in recovery and wiping it clean. Here's how to do it:
1. Turn it off (hold Power Button for a few seconds)
2. Hold Power Button + Volume Down for some seconds
3. When you enter fastboot mode (with the android robot on screen), release the buttons
4. Use Volume Down to choose Recovery Mode and press Power Button to enter it
5. It will show the Android Robot with "No Command" on screen, when you get on this screen, hold the Power Button and press Volume Up then release the buttons, you will get into Recovery Mode screen
6. At Recovery Mode, choose Wipe data/Factory Reset and confirm when asked.
This worked on mine.
(link to procedure: https://www.hardreset.info/devices/motorola/motorola-one-vision/recovery-mode/)
It will wipe your phone clean. If after that it don't work right, you better get your phone to warranty.
Same thing happened to me after changing default USB behaviour in developer settings.
Once I set it to file transfer, my phone rebooted as soon as I put the USB cable in.
It went to a bootloop a couple of times before it booted up to lock screen, but it rebooted again once I entered my lock pattern.
Only way to solve it was to factory reset
Moto is aware of the problem and working on it afaik.
Hopefully it will be fixed with the next update.

I was wrong... It tried with other launchers, same problema. I've read that some phones with problem in the fingerprint sensor have this behaivor. As soon as you add fingerprint as the unlock option, It may reboot randomly or when you try to unlock.
I've wiped It again and confirmed this behavior on mine. I'm going after warranty on monday.

I've made new tests on my Motorola One Vision... That's the problem. As soon as you set the default USB mode to file transfer, my phone starts to reboot even without plugging in the USB cable...
I've wiped it clean, started with the bare minimum, just logged on Google Play Store. I activated the default USB mode to "File Transfer" on the Dev Options.... With no lock option, it works OK. As soon as you set ANY locking method (pin, pattern, fingerprint) it reboots when you try to unlock the phone...
Seems like the only way to solve it is to keep the default USB mode unchaged.

Yes. For now we have to change usb mode from the notification panel each time, untill they got it fixed.

You disabled only fingerprint? Are you using any other unlock method, or just swipe? Mine got into bootloop even if I add a pattern.
when device restart swipe down status bar press setings then unlock and remove fingerprint
After you have changed the default USB mode to "transfer" on the Developer Options, you cant do that. If you have any sort of lock in place that's different from "swipe to unlock", your phone will reboot on any try to unlock it, even if you try to get to settings (it will ask to unlock, then when you try, it reboots).
If you get into the "bootloop", the only way to get out of it is to enter recovery and wipe the phone. The only way to avoid the bootloop is to a) don't change default USB mode to "transfer" on Developer Option or b) only have "swipe to unlock" as the lock option.
If you set a) and anything different then b), you get stuck in bootloop.
I was sad because I'd need to make a hard reset on my phone after this bootloop but then I tried to start it connected in my PC through USB and then BAM it worked out, boots without restarting, it worked out for me, it should for yours too!
Just wanted to confirm, for all those falling foul of this little bug, that Riverm4n's previous advice does indeed work. And saves the heartache of a full system reset..
Just wanted to clarify the guidance a little..
So with the phone on, and on the lockscreen, plug into your PC.
Let Windows do it's driver install thing of it's the first time it's been plugged in..
Then type in your unlock code on the phone..
Potentially could still go into the reboot again, just leave it plugged into your PC and the next time the phone comes on typing your unlock code in should see it unlock without rebooting!!
Don't forget to disable the developer settings or change the usb thing back!!!

Yeah the problem is because is enable fingerprint and default USB configuration was changed.
Just like to thank OP for this - just received a new Vision - & while setting up I had enabled Developer mode mainly due to problem with PC not seeing phone & 1 tip I read was for 'USB Debugging' to be switched on
- while in that menu I decided to force USB file transfer over 'cos of the annoyance having to select it each time I plugged phone in to transfer some pics/doc etc over
Next time I picked up phone it was in boot-loop & I thought it was broken ... PANIC STATIONS !!!!
Factory reset fixed it
- & since being new phone I didn't lose too much of the stuff I had been reinstalling/replacing (which were mainly apps to replace missing 'functions' I had on old phone such as a 'repeat notification/flash camera LED' if unread)
Did lose some game progress on a couple of games I have/had, which is annoying (wish we had a APK Data backup that didn't need root & which isn't Helium since that seems pretty unstable for me atm but then again it's not been updated for a while) but I think I can live with that
Once again thanks
Well, happened to me. I certainly wanted to avoid factory reset. It's a known bug being reviewed by Motorola/Lenovo. Happens when you change the USB connection default action in developer mode and you have any sort of screen lock.
Here is what I did to avoid factory reset, I had fingerprint lock with code.
1. After boot you get to screen lock. I you try to unlock with the code it reboots.
2. In that code enter screen, use a finger not enrolled. You'll see a message that fingerprint was not recognized.
3. Enter now your code and the device won't reset this time.
4. Go to developer options and rollback the USB default action to "no data transfer".
or
1. Factory reset
or
1. Wait for a ROM update
or
1. Return the device to seller and get another one
Avoiding factory reset!

Thank you for sharing this, it actually allowed me to fix this without wiping everything! I hope they patch this issue soon. I had just finished setting everything up and I thought I would have to start again.
