Hey guys, Whenever I try to do stuff in recovery mode (like installing the Voodoo lagfix or backing up using ROM manager), I get a "signature verification failed" message. My phone is a froyo 2.2 Samsung Galaxy S GT-i9000, rooted (used z4root) and has OCLF 2.3 installed, but I had this problem even before it was rooted (when I tried to install the Voodoo lagfix). This are the messages I get when I try to backup my ROM using ROM manager: update media, please wait update media, finished -- Install from package... Finding update package... Opening update package... Verifying update package... E: failed to verify whole-file signature E: signature verification failed -- Appling Multi-CSC... Istalling Multi-CSC Installation aborted. Help will be greatly appreciated!
