Notsure Can't install security certificate

Hey Guys,

I posted the earlier, piggy-backed on another thread, and didn't get any responses. Thought I'd try it out here.

I have a Nexus 4 with Jellybean 4.2.1 - no root. I exported a websites' security certificate from my PC (using Chrome) then moved the .cer (X509 DER) file to the root folder on my "SD" card. I went into settings/security/install from storage. I get a pop-up identifying the certificate available to install. I click install and it says "install complete". Then I go into "Trusted Credentials" and the new certificate isn't there in the "System" or "User" installed certificates.

I tried an application called "Android Certificate Installer" from the Play Store and it didn't help.

While I can still browse the website, I can't download files from it. I tried the process after uninstalling my launcher (Nova) and security apps (AVG and Lookout) and it didn't help.

I did this process with my Motorola Droid X with Gingerbread (2.3.6) several months ago and it worked without incident.

Any ideas for a fix? Anyone have this problem? Has anyone successfully installed user certificates on their Nexus 4?

Yes. I had that checked when I was trying the install. Thanks for the idea to check the unknown sources.

The problem is fixed, however, I'm not completely happy with the solution. For some reason, it didn't work when I tried installing the certificate for the website. I had to install the root certificate for it to work. I'm not happy with this because maybe that means other websites are also going to be considered secure since I have the root certificate. Anyone know if this is true?

No problem glad to hear you got it somewhat fixed.

Any other site with a certificate signed by the same root CA will also be trusted. Was the signer at least a known certificate authority (with a reputation to uphold)?
