Hi,
I'm having a few problems trying to sign a file to change my GPS settings.
I downloaded a zip file that did change the settings, which totally broke my GPS.

I tried to revert to the original files by creating a zip file with my original GPS files, Signed it and got a signature verification failed when I tried to install.

I tried modifying the original zip files with 7 zip but got failed to verify whole-file signature, and signature verification failed. when I tried to install.

Signing the zip file edited with 7zip got me back to just getting signature verification failed.
I'm using a GSII running ICS 4.0.4 from Orange.

Any help would be greatly appreciated.
