Odd captive portal problem

Hi,
I am hoping someone may be able to assist me with an annoyance I have with my Mate 20 Pro
The wifi check URL is set to xxx.hicloud.com and hicloud.com is blocked on some WiFi networks I use (and the admins will not whitelist it).
I have tried to use the ADB commands to turn it off, change the check URL and change the mode. None seem to work.
Is there any way to permanently disable the captive portal or properly change the URL to a google one on the Mate 20 pro?
Below are the commands (amongst many others) that I have tried with no luck. I have tried setting it to Apples, Googles Microsofts etc.
adb shell settings put global captive_portal_http_url http://www.google.cn/generate_204
adb shell settings put global captive_portal_https_url https://www.google.cn/generate_204
adb shell settings put global captive_portal_fallback_url http://www.google.cn/generate_204
adb shell settings put global captive_portal_other_fallback_urls http://www.qualcomm.cn/generate_204
settings get global captive_portal_detection_enabled 1

Need Help Disabling the Multi User in Android 7

I wanted to disable the multi-user feature in Android in my both Motorola phones, one has Android 5.1 and other has Android 7. I have been successful in Android 5.1 phone through the CMD command using ADB tools, the command I ran is this to disable it:
Code:
db shell settings put global guest_user_enabled 0
And the result is this that the user icon under the notification swipe on the top right does not work now it does not do anything when tapped.
Now the same command I am running in my Android 7 phone is not working and the user panel is same as it is, this is where I need your help, what wrong am I doing or is there any change in the command that is need to be done. I just want it disabled like in Android 5.1.

Retail mode removal

Please could someone kindly show me how to remove the retail mode on my new V60 ThinQ handset.
没root好像删除不了吧,你试试看能不能停用
Mod edit
It seems that you can't delete it without root, you can try to disable it

This worked for me for the LG V60 demo unit...I found this on the net.
1)
Follow those instructions for removal of the app,
What is not included in the above instructions, which is required fo the V60 is "disabling device admin"
So basically
1) install device drivers for LG phone that works.
2) Install Android SDK or for easier way just DL and install Minimal ADB and Fastboot
minimal_adb_fastboot_v1.4.3_setup.exe | by shimp208 for Utilities
Download GApps, Roms, Kernels, Themes, Firmware, and more. Free file hosting for all Android developers.
androidfilehost.com
3) Follow instructions and learn how to run adb commands
4) disable device admin
---------------------------------------------------------------------------------------------
to disable device admin: run commands
adb shell
am start -S com.android.settings/.Settings\$DeviceAdminSettingsActivity
uncheck retail mode admin and deactivate it. reboot from the shell with reboot.
---------------------------------------------------------------------------------------------------
5) remove app
To uninstall Uninstall retail mode app : run commands
adb shell pm uninstall -k --user 0 com.lge.retailmode
reboot from the shell with reboot.
Demo mode locks removed
----------------------------------------------------------
I found the above instructions online. I believe it comes from Root Junky.....same person that made the video above
If you do a full reset, the retail mode gets installed again so you would need to run this same process.
Also If you want to use the playstore. I had to first ADD google account in settings. I couldn't just click on playstore and then add acct.
Have not figured out how to run some google apps like DRIVE

Did you bypass the 50% battery limit? I wonder if it's like the Note 7 where the limit is baked into the software or it's just the retail mode.

This worked great, thank you. After enabling developer tools and USB debugging, step #4 is key. In the video it is done through the security settings, but at least on my V60 they were locked by the admin, so the adb command was required.
No into trying to charge beyond 50% with the phone off, and I´ll have a perfectly functional phone for what I wanted it.
Found from another thread that the phone could be charged 100% when powered off.
To power off, one might need this code L310MC570G.
After removal, did the lg v60 have full storage (128GB or 256GB)? and did the camera work in all modes? Thanks.

How to enable USB debugging for Samsung S21 in recovery mode?

Hello,
There is an stock Samsung Galaxy S21 with stock Samsung / phone operator ROM, where the owner forgot his password (not the PIN code).
I don't want to wipe the phone, as owner wants to access the data store on the phone.
It is clear, that once USB debugging enabled, I can use Android SDK tools (adb.exe) to access the file system to delete the password key files to remove the password (adb shell -> cd data/system -> su -> rm *.key)
Since the phone is locked with password, i can't access settings to enable USB debugging.
Is it possible to enable USB debugging in the recovery menu?
Thank you for your help!
Not possible.
