[Android General] badabing2003:
People who are having problems mounting /system rw

Did you manage to figure out how to work around that issue.

Dirty Cow worked fine and got the privileged user

Tried with just run-as and also as su

Confirmed I was root in both cases

But every time I try to mount system rw, the screen flashes, adb kicks out of shell and the screen freezes.

All I can do is power off the car.

It doesn't matter if I execute it manually

mount -o remount,rw /system

or execute it through nefarious.sh

every time it's the same story, freeze when it does the remount.

I looked at running processes as root to see if there is any obvious watchdog process that is causing this.

Couldn't notice anything obvious.

Here's the list in case anyone notices something that sticks out.
