Device Administrator Locked Device - Huawei Mate 9 Questions & Answers

Anyone else experience this issue.
Been like this from Day one.
You can see an example of normal pin lock and this other random device locked screen for reference

Use screen unlock options on encrypted devices

Hi developers,
I need some help. If it is possible, please acknowledge ASAP. Thanks in advance.
My phone: LG Optimus E975 international version, ROM is official, rooted.
I have activated email exchange account(corporate), so it automatically set encryption on device and I can unlock the screen only with PIN or Password. It disables screen lock options: Swipe, Face Unlock, Pattern (In description there is written: "Disabled by administrator, encryption policy, or credential storage").
I want to use my phone's Swipe/Face/Patthern screen unlock features as before.
I found an app[SkipLock] in playstore
but it enables Swipe options only when WiFi is enabled and only with predefined networks.
Can anybody advice any other app which has similar functionality, but without dependency of WiFi, just always enable Swipe option.
I've searched on playstore, google, etc. and didn't find what I needed.
Thanks,
Hayk

[Completed] LG G3 knock code screen lock method disabled after installing certificate

Hello. After I installed this certificate (lrz.de/services/netz/mobil/vpn/anyconnect/rootcert.crt) I am no longer able to use knock code as a screen lock method. I found out that the name of the certificate is Deutsche Telekom Root CA 2 and disabled it from the trusted credentials menu, but I am still not able to select knock code in the lock screen -> select lock; the options Swipe and Knock Code are white and cannot be selected (It says disabled by administrator, encryption policy or credential storage)
Any help would be much appreciated
Hi, thank you for using XDA Assist. I see you've posted this question here, http://forum.xda-developers.com/lg-g3/help/lg-g3-knock-code-screen-lock-method-t3112921 That is the best place to ask. In the future, please avoid posting the same question in multiple areas. I'm going to close this thread.

Face Unlock and Fingerprint no longer available for unlocking phone

So my Dad uses a Galaxy Note 10 Plus. He works at a high level judiciary position i cant mention, so information stored on his phone are govt. classified stuffs. Security is very vital.
He is almost 70 , so memorising pins and password is not his thing.
Therefore he uses Face Unlock/Face ID feature and Fingerprint scanner for unlocking phone and securing his apps.
But this morning, for God knows what reason, his phone can ONLY by unlocked via GESTURE PATTERN.
The thing is, Dad never uses gesture pattern, he must have set it when he first recieved the phone from the govt. He doesnt recall the gesture anymore.
All the officials have been trying their luck with the gesture unlock to no avail.
He needs to recover his phone data fast.
Is there a way for him to unlock his phone using face ID, fingerprint, or even email authorisation or something like that??
As far as I know, after you've tried many times, you will get a messages "Forgot pattern" on the lower left corner of your lock screen. Touch Forgot pattern and enter Google Account info to clear the lock.
Just hope he can still remember the password for the google account!
Just keep on trying until the phone starts asking you for the account (mail) and it's password.
Use the account data (password) to unlock the phone.
It is possible that his employer has the phone under MDM (Mobile Device Management). That is very common on mobile devices that access secure information from an employer. It allows them to control settings on the phone. If so, they may be the ones that changed the settings and they also may be able to unlock the phone.

Motorola G5 Plus Bootloader

I typed in the command to get oem_unlock_data and got my devices string. I input it into fastboot and it says "phone not eligible". I previously had a Motorola G5 plus and had no issues and aft r checking the phone is definitely eligible. I put the Gmail I use onto the phone from my Motorola account and am still having errors. I read a thread stating my device id may be within settings option of phone and if i take off this setting it may work. I cannot find this option within settings. Any ideas on how to unlock bootloader on an eligible device that is telling me is ineligible? My device also says oem_locked in bootloader screen so I know this is the case. Any input would be highly appreciated.

Go to system settings>developer options, find the OEM unlock setting and toggle it to the enabled position. To enable developer options, go to system settings>about>software info>build number(or wherever your build number setting is located in your device's settings). Tap on the build number 7-10 times quickly, this will enable dev options. Then go back to system settings and you'll see developer options has been added to the list somewhere at the bottom.
Then try your unlock method.

Total Noob Question - OEM Greyed Out, Need OEM unlocked asap Pixel 3

Hello there and thank you for your patience, I had previously considered myself smart until yesterday. You see I'm new to all this, just a bb, but I find it fascinating.
So I sold my phone pixel 3 to someone who want to have lineageOS on google Fi and wants to make sure the OEM is unlocked. Phone has sim card slot
Not knowing anything I looked it up completed the steps to get developer options, OEM greyed out, ok so I proceed to look up articles and videos, finally found what seems to be a legit solution here
https://forum.xda-developers.com/pi...izon-pixel-t3796030/post83674835#post83674835
after downloading more software than I needed and making several attempts to access the adb command prompt on my macbook pro, I decided to borrow my friends pc to try and do it
Downloaded https://developer.android.com/studio/releases/platform-tools platform tools, unzipped, shift right click in folder, no command window option
I decided to after following the instructions on the phone, just hit the up volume key and power to turn it on, it says "no command" I'm guessing because I dont have the window up and cant seem to figure out how to get it up
Now I'm. back on my macbook pro and I'd like someone to please help me, preferably on macOS but I'll take any help I can and go back to my friends broken pc if I have to (touch screen broken and keyboard doesnt work, I got a keyboard, but the broken touch screen goes crazy and it's really frustrating.
Anyway sincere gratitude to anyone who can help me as I am desperate
Update: went back to pc unzipped platform tools, shift right clicked and there was an option for powershell window, however it did not recognize any adb commands :/

I know nothing about macbooks, but according to this article you have to change some system settings to open a terminal window.
https://www.groovypost.com/howto/op...nal-window-specific-folder-windows-mac-linux/
Can you open a terminal window in any folder? If so, just do a cd command to the platform-tools directory.
Regarding your powershell window, it sounds like you are not in the platform-tools directory. Do a dir command. Do you see the adb file? If so, try ./adb. If not, do a cd to the platform-tools directory.
Do you have a Verizon branded phone? If so, you probably cannot unlock the bootloader. The link you pointed to is for a Pixel, not a Pixel 3.
If your OEM button is grayed out you are done, you can't unlock that phone.
Hi All,
Apologies, this is my first post, I cracked something trivial, but didn't find the steps or the same situation anywhere, so posting my version of events. This guide is based on the following situation
Bought a Google Pixel 3 XL - CARRIER LOCKED phone off ebay (Locked to EE)
- Running Android 10 - working fine - pre wiped
- EE SIM installed
- Wifi Connected
- Based in the UK
- I need to root this phone to perform security testing
So, for me, because the phone is locked to EE, when I did tried to enable OEM unlocking in dev options, I got the dreaded OEM unlocking unavailable on carrier locked devices.....:
Details:
Enable DEVELOPER MODE
SETTINGS > ABOUT PHONE > Hit “Build Number“ 7 times > Enter your pin/pattern
Go To Enable OEM Unlocking
SETTINGS > SYETEM > ADVANCED > DEVELOPER OPTIONS > OEM UNLOCKING option
However,
You end up with “OEM unlocking unavailable on carrier locked devices” and the option greyed out and disabled (Silent sobbing in the corner by my wallet)​​(See attached my mocked up screen shot of this)​​OEM unlocking is step 2 of every rooting tutorial I’ve seen (the 1st being DEV OPTIONS!) (Silent sobbing in the corner by me!)​
Reading many forums, all hope was lost, lots about Verizon phones, and specific IMIE numbers called out for versions to watch out for, blah blah until a passing comment about getting the Carrier (EE) to unlock.​
EE do this for FREE if YOU bought the phone from THEM….or they charge £8.99 for 2nd hand phone unlocks
1) So, call EE on 150 (UK)
2) Give them the IMIE number of the phone
SETTINGS > ABOUT PHONE > IMEI number​
3) They fill out a form and send to their back office “unlock team”
4a) Short Story – I called back and was advised to update my phone...the end​
4b) Long Story - I was told this would take 24 hrs, and they would send me an email with instructions…this never arrived, so I called back, only to be told there was a back log and it would take 1-10 days!! 5 days later, no email, no codes, no love! so I called back begging for an escalation, I was told there was a note on the account saying it was done! and the phone just needed an update….(no code, no email, no call, if I was waiting at a restaurant for you EE, I'd of left!)​
5) Next update Android to the very latest version
SETTINGS > SYSTEM > ADVANCED > SYSTEM UPDATES​​6) Wait the age for it to install and “optimize” the apps
7) I checked for more updates, found “A security patch”, went through the process again….7 more times! (took me a couple hours!)….I repeated this process until there were no more updates to collect (back to step 5 you go!)
8) Check:
SETTINGS > SYETEM > ADVANCED > DEVELOPER OPTIONS > OEM UNLOCKING option = still locked for me at this point.​
9) Perform a FACTORY RESET
SETTINGS > SYSTEM > RESET OPTIONS > DELETE ALL DATA (FACTORY RESET)​​10) Let it Reboot
11) Re-set up
Enable DEVELOPER MODE...again​SETTINGS > ABOUT PHONE > Hit “Build Number“ 7 times > Enter your pin/pattern​​Go To Enable OEM Unlocking...again​SETTINGS > SYETEM > ADVANCED > DEVELOPER OPTIONS > OEM UNLOCKING option​
BOOM! OEM unlocked! (for me at least)
Long oand short of it - get EE to unlock and confirm > update the [email protected] out of the phone > perform factory reset
I hope these saves time for someone out there
D2
