I downloaded the froyo OTA update and got the dreaded yellow "!" in the triangle. I tried booting into Recovery Mode. When I try to choose "apply sd card :update.zip", I get: E: failed to open /sdcard /update.zip (No such file or directory) E: signature verification failed Installation aborted Ideas? Edit: I don't see it on the sd card (though it finished downloading and prompted me to install) and I can't get it to prompt me to download again. Oh and if it matters, it was 49.5mb. EDIT: The answers are all here now. Please read the entire thread before trying to alter your phone, just in case there's useful info you haven't seen yet.
