Hi there! I've been reading this forum for awhile but can't find a solution to my problem... 1. I rooted my 2 HTC Desires 2 months ago, what went fine. Have been able to install apps that request root. And on 1 Desire I have put the Nexus1 Froyo OS. 2) Now when receive a OTA: error 3) I tried the manual update: error Both phones came from HTC directly, any Sim Card is useable on them. I first get the error "E:Can't open /cache/recovery/command", then I get: "Verifying update package E: failed to verify whole-file signature E: signature verification failed Installation aborted." Any idea what's wrong? Thanks for helping me out.
