I'm in an annoying chicken-and-the-egg loop. Android Browser (the stock browser) is rejecting a bunch of sites certified by Comodo certificate authority. I'm on Comodo's site trying to download their AddTrust External CA Root, but I'm not getting the prompts to allow the download. The download never completes.
I want to try a sidestep the Android Browser problems by installing the CA root certificate in the certifcate store over a tether using ADB. Unfortunately, I can't find the ADB commands to do it:
$ adb --help 2>&1 | grep -i cert $
How do I use ADB to install the damn certificate?
If I can't use ADB, then what tool does Android provide to install one?
The phone is a Samsung Galaxy S4 with Android 5.0.1. It is stock and not rooted.
I'm familiar with Add & remove certificates from Google Help and How to install trusted CA certificate on Android device?. The Stack Overflow question is old, and it predates ICS where the store changed.
