Enabling USB Debugging on Bricked phone (Stuck on boot)

There were many similar queries about 'How to enable USB Debugging' on bricked phones. I have,also, seen and read many other instructions given on many other sites. But they gave all the same answers. e.g- "turn on your phone, connect to the PC, go to setting, tab Developer and Check USB Debugging". But now my question is : If a phone is bricked and stuck on boot then how do we can enable the USB Debugging when missed on first??? :confused:

Now I bought recently a brand new (used just for 4 days) MICROMAX CANVAS JUICE 2 AQ5001. I have already rooted my new phone with 'Kingroot Application. But after when successfully rooted I tried to replace the chinese application with SuperSu-Me then it got bricked stuck on boot when processing to reboot it.

So can anybody tell me that is there no any other way or methods or a PC applications to get through the phone system setting and enable the USB Debugging? Please.

Help enabling USB-over-ADB Pumpkin Duo Core Kitkat 4.4.4 infotainment system

Has anyone tried and succeeded in enabling USB-over-ADB on an in-car infotainment system? I just rooted my Pumpkin Kitkat 4.4.4 infotainment platform to enable USB debugging but when I connect it to my laptop, nothing prompts and the device doesn't even appear in "Device Manager" under "Unknown Devices"... I also set the infotainment system as "Mass Storage Device" when having a PC connect to it through USB. I though rooting it would solve the issue. I'm doing this for a research project involving Forensics programs but they can't extract anything if they can't find my device.

Please someone help if this is possible as I hit a wall with this...

Knock code enabling / disabling with Tasker

I'm sure the answer is going to be stupidly obvious, but I cannot for the life of me get Tasker to disable the lockscreen (knock code) via a task.

The end goal is simply for me to enable the knock code when I am not connected to my HOME Wi-Fi, and disable it when I am connected to it at home. I've set it up similar to other phones I've used but I simply can't get it to function on the G4 (ever owned LG before so it could be a specific way to do it with them and knock codes).

Tasker is set as a phone administrator. Can anyone either show what profiles/scripts they have that DO work, or walk me through the process?
