Tutorial about power charging.

Post by hardwiredw10 » Mon Feb 18, 2019 2:36 pm

Hi,

Some people have been able to make the lumia 950 charge with cable using a cad.sys file.
But others haven't. So it would be nice for someone who has been able to positively make this work, start some form of tutorial about this subject. From start to finish with all the caveats and necessary steps and options.

To be quite frank it's the only factor stopping me from experimenting further with my Lumia 950XL.
HW Power stuff is where I draw the line - The rest seems to be software related and I'm happy to experiment and beta -test the devs work.
Also I'm unsure about heat problems and such...

And I'm quite sure other people feel the same.

This worked for me:

1. I replaced the cad.sys in C:\windows\system32\drivers (Windows ARM) with the 55,2 KB sized CAD.SYS from the telegram group. (See below.)

2. Then I changed in Device Manger the USB Driver "USB xHCI compatible device" Driver to "Qualcomm USB Filter Device" The Qualcomm driver is available by click on "Let me pick from a list of device drivers".

3. I noticed that my Lumia 950XL only charges when I use the original Microsoft charger or cable from the Dock. Other USB-C chargers and cabels didn't work.

This is some valuable info for when I get my own 950. I have a Qi pad but I prefer a wire.

This work around works for me ....but windows doesn't refresh as fast as I would like to hope.so it sometimes appear that the charging isn't happening

I can confirm this works.
By the way i was not allowed to overwrite the CAD.sys file from within the phone so i had to boot first in mass storage mode using WPinternals and then replace it via the connected computer. After that i followed the steps above and now i can charge while in WoA.
Thanks a ton for the guide!

P.S. Wouldn't it make sense to move this thread in the tutorials section?
